    EFFECT OF INCREMENTAL LEVELS OF AVOCADO POMACE ON PERFORMANCE AND CARCASS PARAMETERS OF BROILER CHICKENS
    (Hawassa University College of Agriculture, 2025) SIDIRAK SINTAYEHU
    The utilization of fruit and vegetable by-products can contribute to the supply of animal feeds, improve feed deficiency, decrease the costs of livestock feeding, and also mitigate environmental problems by converting these wastes into useful human food. This study investigated the effect of different levels of dried avocado pomace meal (APM) in broiler diets on feed intake, growth performance, carcass parameters, mortality and hematology of broiler chickens. A total of 144 day-old coob-500 commercial broilers were assigned to 4 treatments, each replicated into 3 pens with 12 chicks per replicate. Isocaloric and isonitrogenous treatment diet were formulated. The treatments were a control diet without APM (T1), 5% (T2), 10% (T3), and 15% (T4) Avocado pomace meal (APM) inclusion in the total diet. The actual experiment lasted 42 days. Data on feed intake, live weight changes, growth rate, feed conversion ratio, and mortality were taken. At the end of the experiment, two chickens randomly taken from each pen were slaughtered for carcass evaluation. The APM contains 9.07%, 25.61%, 9.23%, 19.07%, 30.55%, and 3070.24kcal/kg DM of ash, ether extract, crude protein, crude fiber, nitrogen-free extract, and metabolisable energy, respectively. The feed intake of broilers decreased (P < 0.05) with increasing levels of APM in the diet. The highest (P<0.05) feed intake and average daily gain was observed for T1 compared with T4 during the entire experimental period. The highest (P<0.05) feed conversion ratio was recorded for T4 and lowest (P<0.05) for T1. In almost all carcass characteristics and non-edible offal the highest (P<0.05) values were obtained in T1 than T2, T3 and T4. The hematological and biochemical profile were similar (P>0.05) among treatment except platelets. The platelets for T3 and T4 were higher (P<0.05) than that of T1. The water holding capacity was similar (P > 0.05) among treatments. The average cooking loss for T4 was greater (P<0.05) than T1. In conclusion poor performance by the birds was observed in APM fed treatments indicating that avocado pomace meal is not a suitable feed for commercial broilers. Further studies are required to establish the causes of the poor performance of broilers consuming APM whether it can be rectified.

    FATTENING PRACTICES FEED RESOURCES AND MARKETING SYSTEM OF SMALL RUMINANTS IN PERI-URBAN AND URBAN AREA OF DODOLA TOWN, WEST-ARSI, OROMIA, ETHIOPIA
    (Hawassa University College of Agriculture, 2025) GAMADA KARICHO CHAWICHA
    The study was conducted in peri-urban and urban areas of Dodola town in Dodola woreda, West Arsi Zone of Oromia Regional State, Ethiopia, with the objectives of identifying and generating comprehensive information on fattening practices, feed resources, and marketing system of small ruminants. The study is composed of two parts; a Survey part and Laboratory analysis part. For the survey parts, a total of 147 respondents were randomly selected from four purposively selected kebeles. The closed and open-ended questionnaire were used for collecting quantitative and qualitative data. The collected data were analyzed using SPSS, version 26 software. Independent sample T-test means comparison was employed for quantitative data. The index was computed for the ranked data. The overall average land holding of the respondents was 1.8±0.2 hectares, out of which 1.6±0.1 hectare was allocated for crop production. Livelihood of the society was highly depended on crop production (61.2%), followed by mixed crop and livestock production (22.4%). The major purpose of small ruminant fattening was to generate income (44.90%), however fattening practice held was a traditional system (85.71), with a low (3.2±0.1) average number of fattened sheep and/or goats per fattening cycles. Available feed resources were seasonal based, thus natural pasture (59.18%) and crop residues (61.22%) were used during wet and dry season, respectively. Improved forage production and utilization as well as urea treatment was not adopted in the study areas. Free grazing (71.43%) was dominant feeding system in the study areas. For the laboratory part; Totally 11 feed samples were taken for laboratory analysis. Six feed samples from both peri urban and urban, three feed samples from urban, and two feed samples from peri-urban area. The average (Mean ± SE) chemical composition (DM, CP, EE, Ash, NDF, ADF and ADL) of feed resources were determined on DM basis. The actual dry matter contents of selected feed types were ranged between 33.9±0.4 of mixed grass in peri-urban area to 86.8±0.1 of screened barley by-product in urban area. The highest (28.6±0.0) CP content was recorded in linseed cake, whereas crop residues contain low (3.2±0.1-4.7±0.0 of barley straw and 3.8±0.0-4.5±0.0 of wheat straw) CP contents in current study area. On the other hand, crop residues contain high content of NDF, ADF and ADL than other feed types selected in current study area. Small ruminants marketing in study area was seasonal, where target markets (71.4%) were used for selling. Producers-small traders (58.50%) selling was identified as the main market channel, with high number of small traders (67.35%) as market actors. Decline in grazing land, feed shortage and disease and parasite were the top three challenges, whereas small starting budget, increased price and high market demand were ranked as 1st, 2nd and 3rd opportunities of small ruminants fattening in current study areas.

    BEEKEEPING PRODUCTION AND MANAGEMENT SYSTEM IN DIFFERENT AGRO-ECOLOGIES OF SELECTED DISTRICTS OF SIDAMA REGION, ETHIOPIA
    (Hawassa University College of Agriculture, 2024) ABERA AGENSA ADAMO
    The study was conducted in the Bilate and Gorche districts of Ethiopia's Sidama region with aim to assess beekeeping production, management practices, opportunities, and challenges across different agro-ecologies (highland, midland, and lowland). About 165 beekeepers from six peasant associations across the three agro-ecologies were purposefully selected. A combination of methods including structured and semi-structured questionnaires, key informant discussions, and honey yields data for three hive types (frame, top-bar/Ethio-ribrab transitional and traditional) were assessed. Data were analyzed using SPSS 2022 software. The majorities (98.18%) of respondents in the study area were males and only 1.18% female house households participated in bee keeping production. Majorities (53.3%) of the households were literate and they were able to read and write while 9% were illiterate. The result showed that over 40% of beekeepers had extensive experience (>10 years), while about 28% were relatively new (<5 years). Traditional hives were the most common type owned by beekeepers. On average, respondent beekeepers hold 6.92 colonies, distributed as 3.92, 8.46, and 6.95 colonies per household in lowland, midland, and highland areas, respectively. Traditional hives: Average annual honey yield varied by agro-ecologies (5.56-5.85 kg/hive).Transitional hives (top-bar and Ethio-ribrab) Yields were higher than traditional hives across all agro-ecologies (8.86-12.55 kg/hive). Highest average yields were recorded in frame hives across all agro-ecologies (10.53 12.55 kg/hive). About 70% of beekeepers reported swarming was a common occurrence. Over 91% of beekeepers reported colony absconding, with drought and shortage of food identified as leading causes. The study showed that only 28% of beekeepers practiced honey straining. Birds and ants were the most frequently reported insect pests in the study areas. Three honeybee types were identified based on color and productivity. The majority of respondents (51.52%) did not undertake internal inspection of their bee colonies. The study showed that Vernonia Spp, Croton macrostachyus, Eucalyptus spp, Persea Americana, Coffee arabica and Cordia africana were some of the major honey bee plants identified by respondents in the study districts. The major challenges of beeping were agrochemical application (herbicides/pesticides), bee predators (ant and birds), lack of market access in villages and towns , and limited market information. The main opportunities of honey bee keeping development in the study areas were existing bee colonies, extension services, abundant floral resources and water for bees, employment opportunities, and Indigenous beekeeping knowledge. Frame, top-bar, and Ethio-ribrab hives showed high honey yield potential in mid- and lowland zones. The study suggests that beekeepers in mid- and lowland areas can benefit from adopting frame, top-bar, or Ethio-ribrab hives for increased honey production. Addressing the identified challenges and promoting existing opportunities can enhance beekeeping sustainability and improve honey production in the region. Governmental and NGOs intervention, on introducing appropriate beekeeping technologies with all accessories, strengthening the management practices through training for beekeepers is important

    EVALUATION OF HONEYBEE HIVE DENSITY ON THE AVOCADO (Persea americana m) FRUIT PRODUCTION AND HONEY QUANTITY AND QUALITY DURING AVOCADO FLOWERING IN DARA OTILCHO DISTRICT SIDAMA REGIONAL STATE, ETHIOPIA
    (Hawassa University College of Agriculture, 2023) SOLOMON FIKRIE
    This study was conducted in the Darra Otilcho district of Sidama region, Ethiopia to assess bee keeping activities, impact of honeybee hive density on the quantity and quality of avocado fruit and to determine the effect of hive density on honey quantity and quality produced. 116 bee keepers were selected using multistage sampling method for household survey from highland and midland agro ecologies. 12 Avocado orchards with an area of 1 ha for each orchard were selected purposively based on ownership of avocado tree for experimental work. For this study, Randomized Completely Block Design was applied with four treatments (0 hive (T1) (only for fruit), two hives (T2) and four hives (T3) and six hives (T4) each with three replications. The result of the study indicated that supplementing pollination by honeybee hives per orchard increased avocado fruit set than the control (no hive per orchard). The largest fruit weight (258gm), fruit length (13.2cm) and fruit yield per tree (246kg) were obtained from treatment four. In the current study, supplementing pollination by honeybee hives per orchard revealed better Total soluble solids, Dry Matter and lower Titratable acidity as compared to the control. Pollen determination of all treatment samples indicated that the mono flora of Persea americana honey consisted of 55.27%, 64.86% and 56.96% for treatment two, three and four, respectively. The highest average of the honey yield per hive was recorded from treatment two (17.66kg) and the lowest mean values were obtained from treatment four (12.8kg). The overall mean of honey sample of all treatments obtained indicated that physiochemical parameters except electrical conductivity (0.98) the rest of honey quality such as moisture content (19.75%), Ash (0.5 g/100 g), HMF (18.16 mg/kg), pH (4.48) ,free acidity (28.2 meq/kg), (glucose (31.52 g/100 g), Fructose (36.47 g/100 g) and sucrose (2.35 g/100 g)) were evaluated in this study to comply with national and internal standards. There is statistical variation (p < 0.05) observed between a honey sample of treatments and that of farmers for Ash, electrical conductivity, free acidity, HMF and Sucrose parameters. The current study indicated that the observed result of honeybee production in avocado orchards was valuable for farmers and strongly suggested that honeybee pollination had a significant role in avocado productivity.

    ASSESSING THE EGG PRODUCTION AND EGG QUALITY TRAITS OF SASSO CHICKEN BREED REARED UNDER TRADITIONAL HUSBANDRY PRACTICES IN MIDLAND AND LOWLAND AGROECOLOGIES OF ALETA CHUKO DISTRICT, SIDAMA REGION
    (Hawassa University College of Agriculture, 2023) MULATU TEREFE
    This study was conducted to assess egg production and egg quality traits of Sasso chicken breed reared in two agroecologies under traditional management system. For the assessment of the egg production practices, 165 households were purposively selected from lowland and midland agro ecologies who had three and above Sasso chicken. The egg quality traits were assessed from Sasso chicken breed reared by the households in both agro ecologies. A total of 200 eggs were used to determine the external and internal egg quality traits from sampled households. The collected data were analysed by SPSS Version 26. The results indicated that average age at first egg laying(160) days, average clutch length (22.9) and eggs/hen/year(214)were in lowland agroecology. Average age at first egg laying(149) days, average clutch length(23.9) and eggs/hen/year(232) were midland. Agro ecology had highly significant effect on all external egg quality traits except on egg width. Egg weight(57.58g) and egg length(57.46mm) of Sasso chickens was higher(p<0.05) in the lowland than(53.58g) and (55.80mm) in midland. Dry shell weight and shell thickness in the lowland agroecology was higher(p<0.05) than in midland. Shape endex was higher(p<0.05) in the midland than in lowland agro-ecology. Agro-ecology had also highly significant effect on most internal egg quality traits such as: yolk height, albumen height, albumen weight and haugh unit were higher(p<0.05) in lowland than in midland. The yolk ratio in lowland was lower(p<0.05) than in midland agro-ecology. However, albumen ratio was lower(p>0.05) in lowland than in midland agroecology. In conclusion, the Sasso chickens in the midland agroecology were superior in egg production than lowland. However,the Sasso chickens in the lowland agroecology were superior on most external and internal egg quality traits under traditional production system. It is thus recommended to rear the Sasso chicken hens in the midland agroecology for enhanced egg production and lowland for enhanced egg quality traits.

    FEED RESOURCES AND FEEDING PRACTICES OF DAIRY CATTLE IN DALE AND WONDOGENT DISTRICTS OF SIDAMA REGION.
    (Hawassa University College of Agriculture, 2023) MISHAME ALEMAYEHU W/AB
    A study was conducted in Dale and Wondo Genet districts of Sidama region to assess feed resources and feeding practices of dairy Cattle. Household survey using structured questionnaire, focus group discussions, field observations and laboratory analyses were applied to generate the data. Feed samples were analyzed for dry matter (DM), crude protein (CP), ash, neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL) contents and for determination of in vitro dry matter digestibility (IVDMD). Purposive sampling was used to select the respondents. A total of 140 respondents (Dale = 80 and Wondo Genet = 60) were purposely selected based on dairy cattle production potential and interviewed individually. The results indicated shortage of feed and land were the major dairy cattle production constraints in both districts of the area. The major feed resources available in the dry season include crop residues 37.1%, hay 25.1% and natural pasture 19.3%, whereas in wet season, 33.6% of the respondents feed their dairy cattle natural pasture, forage and pastures, non-conventional feed resources. Rotational grazing system was practiced highly on communal and private grazing land. The major crop residue used for dairy cattle feeding in both districts were maize stover, haricot bean straw, sugarcane tops, enset pseudo-stem and leaf and bean straws. Majority (85.7%) of respondents were utilizing crop residue for dairy cattle feeding in the study area. The major challenge of using crop residues was the collection and transportation of crop residues from crop land and storage. Private and communal grazing land and also cultivated land boundaries were the major sources of hay production. Desho grass, Elephant grass, Guatemala grass, Phalaris species, Rhodes grass, cow pea and pigeon pea were improved forage cultivated by the farmers in both districts and they can get seeds from government agricultural sectors and NGO. Land and seeds shortage were challenging improved forage production the study area. Residues of coffee, enset by products and banana pseudo-stem and leaf were used mostly as non-conventional feed in Dale district whereas banana pseudo-stem and leaf, enset by products and coffee residues were majorly practiced in Wondo Genet districts as non-conventional feed. Crop residues, purchased concentrate feeds and forage/green leaf and reduction of cattle were used to alleviate feed shortage in both study districts. Most of respondents were providing chopped crop residue for their animals. The highest crude protein contents were found in enset leaf (12.2%) than others feed types. The NDF content of most feed resources across districts was less than 65% and can be categorized as medium quality feeds. Development of improved forages integrated with the dominant farming system, efficient conservation and utilization of crop residue via different treatment options and maximizing the productivity of available individual and communal grazing pasture land using established improved technologies needs attention.

    (Hawassa University College of Agriculture, 2023) MESERET MULUGETA HEWISO
    Pollination is an essential ecosystem service that enables plant reproduction. Avocado is one of at least 105 crops that receive yield benefits from animal pollination. This study determines the effects of honey bee density and hive distance from avocado pollen donor on the number fruit per tree, weight of individual fruit and total weights of fruits per tree. The research was carried out in Darra Otilcho district, Sidama region, Ethiopia. Data was collected through household interview from purposively selected household to know the perception of farmers on pollination and pollinator. For experimental work, four avocado orchards with three replications, totally twelve orchards were selected, each one with an area of 1.5hectare. The treatments were:1)three beehives/1.5ha,2)two beehives/1.5ha,3)one beehive/1.5ha, and 4)control without beehives with three levels of foraging distance ( 50m, 100m, and 150m from the hives) with12 treatments in nested design. The treatments of three and two beehive/1.5ha obtained significant difference compared to the control, with a honey bee per tree of 15.2, 8.7, 6.0 and 2.9, rate of pollination 70, 47.8, 47.8 and 41.1%, efficiency of pollination 16.6, 8.8, 7.2 and 5.4 respectively. As well as total number of fruit per tree 392.2, 309.6, 245.2 and 193.2, average weight of individual fruit 215.3, 204.0, 193.4 and 188.4gm and total weight of fruit per tree, 84.5, 63.1, 47.4 and 36.4 kg for treatments 4, 3, 2, and 1, obtained significant differenceres respectively. The results obtained show that an increase in the density of honeybees per tree, increased the rate of pollination, efficiency of pollination, and total number of fruit per tree as well as average weight of fruit per tree and total weight of fruit per tree. This study recommended three beehives/ha to be introduced in the avocado orchard for effective pollination and increase of avocado yield.

    (Hawassa University College of Agriculture, 2023) GIZACHEW ENDESHAW DEBALKE
    The aim of the study was to assess productive and reproductive performance of local and their crossbred of different exotic blood level of dairy cows and factors affecting their performance in urban and peri-urban, farming system of aleta wondo district sidama region Ethiopia. A total of 155 small-scale dairy cows owners were purposively selected and interviewed with pre-tested structured questionnaire to obtain information. For Monitoring study from 155 farmers 36 Dairy farmers who have lactating cow by identifying exotic blood level of each crossbred animal (0%, <50%, 50-75% and >75% were purposively selected. Monitoring study was also conducted to obtain milk production based on, lactation stages production system and exotic blood level and parity of cows. The results of the study showed that from the follow-up study, the average daily milk yield for local, <50%, 50-75% and > 75% caws was 2.81L, 8.65L, 17.68L and 20.83L respectively. Daily milk yield of the cows found in monitoring study was support milk yield found in survey study. From the survey results, the overall average lactation length for local and their crossbred of < 50%, 50- 75% and > 75% was 7.65, 8.05, 8.95 and 9.65 month respectively and average mean for crossbred was 8.88 months. The mean age at first service (Months) for local and their crossbred of < 50%, 50-75% and >75% was 42.87, 35.57, 21.88 and 17.54 months respectively and average for crossbred was 24.99, age at first calving (Months), for local and their crossbred of < 50%, 50-75% and > 75% was 49.26, 41.56, 27.86, and 26.61 respectively and the average for all crossbred was 32.01, Calving interval (Months) for local and their crossbred of<50%, 50-75% and >75% was 22.41, 16.73, 13.41 and 12.75 respectively and average for all crossbred was 14.29, Days open till conception (Days) for local and their crossbred of < 50%, 50-75% and > 75% was 201.3, 173.7, 87.15 and 86.1 respectively and average for all crossbred was 115.65, and number of services per conception for local and their crossbred of < 50%, 50-75% and > 75% was 3.53, 3.1,1.6 and 1.4 respectively and average for all crossbred was 2.03. There was observed that all exotic blood level of crossbred and local dairy cows are good performed under urban than peri-urban setting. The present study showed that even if productive and reproductive performance of crossbred cows owned by peri-urban and urban dairy producers in study area was comparatively good, it need to advance breeding strategy to assign right exotic blood level at right production system and also supply of improved genotypes and dairy inputs like (feed, health care and artificial insemination), proper breeding management in the study area suggested.

    ASSSESSMENT OF AVIALABLE FEED RESOURECES, FEED MANAGMENT AND UTILIZATION PRACTICE IN DAWURO ZONE, LOMA DISTRCT, SOUTHERN ETHIOPIA
    (Hawassa University College of Agriculture, 2022) MATHEWOS MENGSHA FOLLA
    A study was conducted in Loma district in Dawuro Zone of South Nation Nationality People Region to assess the avialable feed resources, feed management and utilization practice. Primary and Secondary data sources and field observations, structured questionnaire and group discussions were employed to generate data. The study district was stratified into highland, midland and lowland agro ecology. Purposive sampling was used to select the respondents. Atotal of 385 respondents (highland=110, midland=110 and lowland=165) were purposely selected based on those having minimum 3 livestock species and interviewed individually. The results indicated that both crop and livestock farming were the main farming activity in the study area. Shortage of feed and disease were the major livestock production constraints in all agro ecology of the area. The major feed resources available in dry season were crop residues , natural pasture , and crop after math, hay and fodder tree in the study area. During the wet season, majority of the respondents feed their animal natural pasture, fodder tree and crop residue crop after math and hay. Fodder tree was the dominanted feed next to natural pasture in both lowland and mid land agro ecology. Continuous grazing system was practiced highly in low land where as zero grazing (cut and carry) system were practice highland agro ecology. Indoor feeding was highly practiced in highland respondents compared with midland and lowland. Majority of respondents in lowland agro ecology had Common grazing land compared with other agro-ecology respondents.Crop residues and purchased concentrate feeds were used to alleviate feed shortage in all agro ecology of the study area. Majority of respondents could not produce, improved forage for their animals due to land shortage,shortage of rain fall and shortage of land were the main reason that affects production of improved forage in lowland and other agro ecology respectivily.The major crop residue used for livestock feeding in both midland and lowland were teff, maize and sorghum and also wheat and barley straw was the dominant crop residue in high land agro ecology. Most of the crop residue was stocking under the shed in the study area. Most highland and midland respondents stock crop residues in open air and stocked under the shed was used by lowland agro ecology respondents. Majority (69.6%) of respondents were utilizing crop residue for livestock feeding in the three agro ecologys. Only 19.2% of respondents were providing chopped crop residue for their animals. With lack of molasses all of the respondents were not treat crop residue in the study area. 26% of respondents in the study area were practice hay production. Spring water was the major sources of water in the highland and midland agro ecology whereas rivers are mainly used by the households of lowland agro ecology. Most of respondents were providing of water for the animal twice in a day with group and individually in the study area. Development and demonstration of improved forages that can be integrated with the dominant farming system, efficient conservation and utilization of crop residue via different treatment options and maximizing the productivity of available individual and communal grazing pasture land using proven improved technologies needs attention.

    The study was conducted during the main cropping season of 2019/2020 at Assosa in Benishangul-Gumuz regional state. The aim of the study was to evaluate herbage dry matter yield, nutritional quality and biological compatibility of oats-vetch mixtures. The treatments included two oat varieties (SRCP X 80 Ab 2291 and SRCP X 80 Ab 2806), two vetch species (Vicia sativa“ICARDA61509” and Vicia dasycarpa “Lana”) and four levels of seed proportions (100%, 75%, 50% and 25%) of the recommended seeding rates of the two forages. Randomized complete block design was used with factorial arrangement and 3 replications. The results revealed that seedling count at emergence, stand count at tillering, plant height, leaf to stem ratio of oat and vetch were significantly (P<0.05) differed among oat varieties, vetch species and seed proportions. The interaction effect of oat by vetch, oat by seed proportions, vetch by seed proportions and oat by vetch by seed proportions had significant (P<0.05) effect on plot cover and vigor score percentage, dry matter yield (DMY) tha-1,and the quality parameters such as, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent Lignin (ADL), In-vitro Dry matter Digestibility (IVDMD) and crude protein yield (CPY) tha-1. The mixtures of 75% SRCP X 80 Ab 2806 + 25% Vicia sativa “ICARDA-61509”(12.35) gave in the higher DMY (tha-1). On the other hand Vicia dasycarpa sown in pure stands had lower DMY compared to oats vetch mixtures (7.45). In terms of quality, increasing the seed proportions of both vetch species in the mixture resulted in higher CP%, CPY (tha-1) and IVDMD% and lower NDF%, ADF% and ADL% contents. Relative yield total of oats-vetch mixtures at 25% SRCP X 80 Ab 2291 + 75% Vicia dasycarpa “Lana” (1.35), 25% SRCP X 80 Ab 2806 + 75% Vicia dasycarpa “Lana” (1.32), 75% SRCP X 80 Ab 2806 + 25% Vicia sativa“ICARDA-61509” (1.20) and 75% SRCP X 80 Ab 2291 + 25% Vicia dasycarpa “Lana” (1.12) were better compared to the other mixtures and pure stands. Generally, mixing of oat varieties with vetch species at different seed proportions of 75% oats: 25% vetch and 25% oats: 75% vetch produced better dry matter yield, nutritional quality and compatibility in the study area. However, the experiment should be conducted for more years at different locations to recommend the best oats-vetch mixtures for Assosa area of Benishangul-Gumuz Regional State.
