EFFECT OF SUBSTITUTION OF KOCHO FOR MAIZE ON FEED INTAKE, DIGESTIBILITY, AND BODY WEIGHT GAIN OF SHEEP FED RHODES GRASS HAY AS BASAL DIET
(Hawassa University College of Agriculture, 2014) AMAN GETISO
A study was conducted to evaluate the effect of substitution of kocho for maize on feed intake, digestibility, and body weight gain of sheep supplemented Rhodes grass hay as basal diet. Twenty four yearling male Adilo lambs with initial body weights of 15.03 ±1.96 kg (mean ± SD) were used. Animals were grouped into six blocks of four animals, and fed with 74% maize + 25%noug cake + 1% salt (T1), 46.25% maize + 27.75% kocho + 25% noug cake + 1%slt (T2), 27.75% maize + 46.25% kocho + 25% noug cake + 1% salt (T3), and 74% kocho + 25%noug cake + 1% salt (T4). Rhodes grass hay was offered as a basal diet ad libitum. The supplements were offered at the rate of 300 g/d during the feeding and digestibility trials of 72 and 7 days, respectively. There were no significant differences (P>0.05) in dry matter, organic matter, acid detergent and Metabolizable energy intake, dry matter and organic matter digestibility and weight gain among treatments. Lambs in T1 had the highest (P < 0.05) CP intake (49.03 g/d) followed by T2, T3 and T4 with 42.85, 39.35 and 33.50 g/d, respectively. Nitrogen intake was lowest (p<0.05) for sheep fed T4 and highest (P<0.05) for sheep fed T1, T2 and T3 diets which had comparable values among themselves. The highest (P<0.05) N retention was for T2 and the lowest (P<0.05) was for T1 and T4, while T3 had an intermediate value. The study conducted inferred that kocho can replace maize without any unfavorable effect on nutrient intake, digestibility and weight gain. It was concluded that kocho could be used as an alternative good energy source to replace maize in areas where its economic advantages are practicable.

ASSESSMENT OF MANAGEMENT PRACTICES, PRODUCTION PERFORMANCES, AND SOME EGG QUALITY TRAITS OF CHICKENS REARED IN LOKA ABAYA DISTRICT, SIDAMA ZONE, SOUTHERN, ETHIOPIA
(Hawassa University College of Agriculture, 2019) HAILU DUKAKO
This study was carried out in Loka Abaya District, Sidama Zone of Southern Ethiopia. So far there are limited studies conducted in Loka Abaya targeting comprehensive description of the production performance, associated constraints, management practice, and egg quality traits of backyard chicken in rural communities. The objectives of the study were to assess chicken husbandry practices, production, and reproduction potential and evaluate some egg quality parameters in the study. The agro ecology was arranged systematically, Kebeles were selected purposively, and random sampling was used to select 120 chicken rearing households from two agro ecologies. Household survey, key informant interview, and focus group discussions were employed to draw out appropriate data using pre-tested semi-structured questionnaire, interview schedule, and discussion guide. Concerning egg quality determination, households who have native chicken and cross chicken ecotypes were identified from each agro ecology and, 200 eggs were collected for quality parameters generally. Chi- square test and ANOVA were employed to analyze the statistical difference between two agro ecologies. Accordingly, the result revealed that the mean flock structure of chicks, cockerels, pullet, hens, and cocks, were 5.4 (0.01TLU), 0.9 (0.01TLU), 1.5(0.01TLU), 4.5(0.01TLU) and 0.8 (0.01TLU) heads per household, respectively and mean flock size of chicken 9.4(0.01). The current finding also indicated that the major feed resources were scavenging and supplementary feed (47.5%) and types of supplementary feed was maize and wheat (52.5%). Regarding housing, watering, and chicken constraints; 50.8% of respondents house their chicken with family, 89.2% of respondent provide water freely and predator were major problem followed by disease. Based on survey result the primary purpose of chicken production in the study area was income generation. The current finding also showed that majority of farmers in the study area, purchased veterinary drugs@Oxytetracycline 20% to treat their chicken (47.5%) and also used ethno veterinary medicines (39.2%) and used “Ash “during hatching or egg incubation time to protect eggs from contamination of human hands (90%). The result also indicated that the major determinant factors that affectinfluencing the chicken husbandry practices in the study area include presence of predators, disease, feed shortage, lack of adequate veterinary services and lack of knowledge about modern chicken husbandry practices were identified as the major determinant factors that influence poultry production in the study area. Regarding egg quality parameters; there were difference (p<0.05) between egg weight, egg width, albumen height, albumen weight, yolk color, specific egg gravity, and Haugh unit. An understanding of factors influencing the decision of the respondents were associated with improvement in poultry husbandry critical when formulating technologies regarding with husbandry practices that support chicken production.
ASSESSMENT OF REPRODUCTIVE MANAGEMENT AND EVALUATION OF BOVIPREG FOR PREGNANCY DIAGNOSIS OF DAIRY CATTLE IN SIDAMA ZONE OF SOUTHERN ETHIOPIA
(Hawassa University College of Agriculture, 2019) MULUGETA TESFAYE
The assessment of breeding practice and reproductive management and evaluation of Bovipreg kit for early pregnancy diagnosis of crossbred dairy cattle was conducted in three districts of Sidama zone namely Arbegona, Bona and Bensa. The districts were categorized under high altitude and mid altitude to assess the existing breeding practice and reproductive management of dairy cattle. A total of 90 respondents were randomly selected from 6 kebeles for the survey. The data acquired from the respondents were analysed using the GLM of SPSS. The survey result revealed that the average age at first calving for crossbred was 3.3 years for the high altitude and 3.5 for the mid altitude and had no significantly difference (p>0.05) among the two altitudes, the result also indicate that the mean calving interval of 458.23 days and 439.9 days for the high altitude and mid altitude respectively and had no significantly difference (p>0.05); also daily milk yield of the dairy cattle in the current study area had no significant difference (p> 0.05) between the two altitudes of the study area. As opposed to this there was significant difference (p<0.05) between the two altitudes with regard to lactation length and calving to first service insemination. The breeding practice in the current study areas shown 71.1% of the respondents were using natural mating of bull irrespective to the altitudes, but the pedigree of most of breeding bulls in the study area was not known clearly. The study further revealed that few of the respondents were aware the importance of heat detection to decide time of insemination. Thus in most cases the AM/PM rule for insemination was not followed properly and this is one of the cases to have low efficiency of the AI service in the study area. Due to this and related factors most of the farmers gradually shift their breeding system from AI service to bull mating in both study area. With regard to feed the main source of feed for dairy cattle was natural pasture followed by crop residue in both altitudes of the study area. Most of the respondent irrespective of the altitudes agreed that they kept their all livestock species including dairy cattle together with the family dwelling. In addition to survey part of the study action research was conducted to evaluate Bovipreg kit for early pregnancy diagnosis of crossbred dairy cattle in two PAs of Bensa district. A total of 44 crossbred cows were selected and randomly grouped to 2 groups (22 cows per a group) for early pregnancy diagnosis by using Bovipreg at 18 - 22 days post insemination. The groups were test for PD by using blood serum (group 1) and milk (group 2). The accuracy of Bovipreg kit for positive pregnancy was 81.18% for blood sample and it was 72.73% for milk sample and had significant difference (p<0.01) among the two samples. Use of Bovipreg kit can be an effective tool to identify the pregnancy status of dairy cattle much ahead than most of the current existing methods and has a fundamental important to improve the reproductive management of dairy cattle.
ASSESSMENT OF PRODUCTION SYSTEM, MORPHOLOGICAL TRAIT AND EGG QUALITY PARAMETERS OF INDIGENOUS CHICKEN IN WEST ARSI ZONE, OROMIA REGION, ETHIOPIA
(Hawassa University College of Agriculture, 2020) DESTA GUTEMA SHURE
A study was conducted in two selected woredas (Heban Arsi and Negelle Arsi) of West Arsi zone of Oromia Regional State, Ethiopia. Production system, some morphometric traits and egg quality parameters of indigenous chickens were assessed. Using purposive multistage sampling a total of 120 households possessing 5 or more matured chickens were selected for study. A total of 360 indigenous chickens were used for determination of morphological traits. Egg quality parameters were evaluated on 240 eggs collected. Extensive management system was practiced in the study area. About 23.3% of households used purposively made chicken houses. Overall mean age at sexual maturity of hens was 6 months and cockerels 5.86 months. Disease, predators and feed shortages were the three major chicken production constraints. Majority of body feather colour of indigenous chickens were red and Red brownish /Kokima followed by White, black with white tips/Teterma, Black, Grayish/Gebsima and Multicolor/Ambasma. All of the chickens possessed normal feathers with the dominant white and red ear lobe colors, yellow shank colors, pea and single comb and plain as well as flat head shape. Overall mean body weight of chickens was 1.3kg. The wingspan length, shank length, shank circumference, comb length, wattle length, body length, back length and keel length measurements were 32.58, 7.74, 3.82, 3.35, 1.44, 30.79, 18.72 and 9.19cm respectively. The average egg weight, shell thickness, egg width, egg length was 39.88, 0.291, 37.80 and 50.64mm respectively with average shape index of 74.72%. The subsequent average albumen height, yolk height, yolk width and yolk color was 4.02 mm, 13.75 mm, 37.04 mm, and 6.77 colour fan of 1-15 respectively with the corresponding Hough unit score of 69.37%. To sum up, both study woredas and sex of chickens looks to approve the traits of indigenous chickens and egg quality traits under traditional managements system. Detailed Molecular characterizations is recommended to assess morphological traits of indigenous Chickens of the study woredas.
ASSESSMENT OF SHEEP PRODUCTION SYSTEM, REPRODUCTIVE PERFORMANCE AND HABIT OF SHEEP MILK CONSUMPTION BY THE SOCIETY IN ALETA WONDO WOREDA, SIDAMA REGIONAL STATE, ETHIOPIA
(Hawassa University College of Agriculture, 2020) ABIOT GARO DUMO
This study was conducted in Aleta Wondo Woreda, Sidama Region to assess sheep production system, objectives of production, reproductive performance and habit of sheep milk consumption. For the study 158 households (HHs) owning at least one milking sheep were selected from Highland and Midland agro ecologies using systematic random sampling method and data were collected using structured questionnaire, key informant interview, field observation and secondary data. The family size was variable ranging from 2-4(44.9%), 5-8(50%) and above 9(5.1%). The mean total land holding was 0.88±.0534ha per with a difference between agro-ecologies. The average sheep flock size per HH was 3.02 ± 0.08 with a difference between agro-ecologies. Generating income, saving, meat and milk followed by manure and skin in their decreasing order of importance were main purposes of keeping sheep. Mixed crop- livestock production system was the dominant farming system in the area. Natural pasture, crop residues and crop aftermath, improved forage and enset and banana were feed resources available in the area. Mostly tethered system of feeding is practiced with no difference between agro ecologies. Above half of the respondents have no experiences of cultivating improved forages. Although feed types used for supplementation differs, all respondents were supplementing their sheep both in dry and wet seasons. Feed shortage in terms of quality and quantity throughout the year was one of the major problems of sheep production. Pond and deep well during dry season and river and pond during wet season were the main sources of water. Majority of the respondents in midland agro ecology suffer from shortage of water due to drying and pollution from coffee industries in dry season. Majority (58.2%) of the respondents house their sheep in main house with a difference between agro ecologies. Controlled mating was a common practice in both agro ecologies. All respondents in the area were selecting and culling sheep for production using different criteria. About 74.7% and 59.5% of the farmers were not castrating and fattening sheep respectively. For sheep, estimated average age at first service is 7.9±0.07months for male and 9.5±0.11months for female, age at first lambing 13.5±0.11month and lambing interval 8.04±0.06 month with a difference between agro ecologies. Most (76.4%) of the respondents in Highland area are consuming sheep milk whereas the inverse is true for Midland agro ecology with 90.7% due to unawareness. The constraints were land and feed shortage, disease and parasites, lack of improved breed, lack of extension service, water shortage and market price fluctuation. The major opportunities ranked by respondents were high market demand, increase of urbanization, and suitability of agro ecology and government attention for sheep production in decreasing order of their importance. Therefore, to use the available opportunities, the identified constraints should be solved in Aleta Wondo Woreda.
ASSESSING MANAGEMENT PRACTICES OF EXOTIC CHICKEN BREED, REARED IN SHEBEDINO DISTRICT, SIDAMA REGIONAL STATE, ETHIOPIA
(Hawassa University College of Agriculture, 2020) ALEMU ALASO ADISO
Exotic chicken management practices, performance and challenges and opportunity infive kebeles of Shebedino district in Sidama Regional state, Ethiopia were assessed. Sample size of HHs for the survey was determined using a multi stage sampling technique and Processed data analyzed by using statistical package for social science (SPSS) version 20.0 soft ware. Five kebeles (2 from highland, 3 from midland and 4kebeles and 1kebele from rural and urban areas respectively) were selected purposively based on potential of production. Total sample size of selected population was 137of which59.85% was male and 40.15% were female. The average family sizes were 5.54 and 5.53 persons with in highland and mid-land of the district, respectively. Age of respondents ranged from 44.5 and 45 years for Highland and Mid-land Agro-ecologies of the district, respectively. Total landholding/HH were 0.5-1 ha (24.8%) and 1.25-1.75 ha (57.67%), 2-2.25 ha (13.13%) and 2.5-3 ha (4.4%) of the respondents both high and mid land agro-ecologies. Average numbers of exotic chicks, pullets, cockerels, hens and cocks per HH were 17, 5.3, 2.6, 7.3and 2.8 respectively, both high and mid land agro-ecologies. Majority of the sample respondents (58.7%) and (63.7%) in the highland and midland of the district respectively; keep exotic chickens primarily for income generation and next home consumption. Commonly distributed exotic chicken breeds were Sasso (49.64%), IB (Issa Brown) (43.06%) and BB (Bovans Brown) (7.3%) in the high land and mid land of the district. Majority of households (71.53%) practice free-scavenging or/and extensive poultry production system and about a quarter of them semi-intensive poultry production system. The exotic chickens rearing experiences of household were ≤ 5 years (8.76 %), 6-10 years (41.61 %) and > 10 years (49.63 %). Majority of respondents (67.9%) used traditional housing with main house. Higher numbers of the respondents (68.6%) obtain from local available feeds.75.9% of the respondents practiced supplementary feeding by maize, kocho, home left over and wheat bran to their exotic chickens. Majority of respondents (82.4%) provided water adi-libitum, whereas 14.7% provided three times per day and the remaining 2.9% offered twicea day. The major diseases reported in the study area, in the order of their importance, were Newcastle, coccidiosis and fowl pox. Bovans brown, Issa brown and Sasso attained sexual maturity at 90-120 days. The predators that most commonly occur and attack exotic chickens were wild cat (local name Ganchara), fox and hawk. Disease, feed problems followed by predators and poor adaptation were challenges of exotic chicken production. Major opportunities of rearing exotic chickens in the study areas were access to market, veterinary service and extension service and adaptation problem of exotic chickens. Government should create awareness on vaccination of chicken against major poultry diseases in the study areas.
ASSESSMENT OF BUTTER PRODUCTION, CONSUMER AND MARKET PREFERENCES, QUALITY AND PRICES IN KINDDO DIDAYE OF WOLAITA ZONE, SOUTHERN ETHIOPIA
(Hawassa University College of Agriculture, 2020) AMANUEL ELIAS LOTA
The study was conducted at Kinddo Didaye district, Wolaita zone southern Ethiopia with the objective of assessing butter production, consumer and market preferences, quality and prices in the area. Based on data collected between April to July 2019. The effect of agro ecology on butter production was analyzed. A multistage sampling procedure was employed to select representative kebeles and households from Kinddo Didaye district. To conduct the study, one sample district (Kinddo Didaye) was purposively based on dairy cow potentiality and butter production. Six kebeles were selected in total (three from midland and three kebeles from lowland). 138 butter producing households were purposively selected based on dairy cow production and butter production from the study district. Besides this different 40 retailers, 10 butter shops and 50 consumers were interviewed. Local cattle are the most dominant milking cows were kept by all six kebeles. Both qualitative and quantitative data were collected, involving household survey. Thus, all (100%) of the respondents were reported that clay pot churn is tool used for butter making. For washing and smoking milk equipments, plant leaves such as Ocimum hardiense (68.1%) and Cymbopogan martini (23.9%) were mostly used in both agro-ecologies. For butter averagely 3.0±0.12 and 2.91±0.01 volume of milk churned at a time in both lowland and midland agro-ecologies respectively. In addition, 17.92±0.13 and 15.04±0.09 liters of milk in both lowland and midland agro-ecologies respectively were used to produce 1kg of butter. Retailers and consumers got quality butter from producer; The destinations of the butter were to different areas in the country, mainly Wolaita Soddo, Hawassa, Addis Abeba and others. All assembler/butter shops sell butter by their shops. Consumers report shows that the quality attributes of butter preferable by consumers were 44% flavor, 32% texture, 20% color and remaining 4% fermentation in study district. The price of butter rise during holy days, non-fasting period and dry season. The challenges of butter production in the area were feed shortage, shortage of grazing area, dry season, price fluctuation and fasting season. The major type of adulteration that reported by consumers were 62.5% banana and 37.5% ‘shenolega’ in the study area
Assessment on Management Practices and Comparative Study on Egg Production and Egg Quality Parameters of Sasso and Local Chicken Breeds in Aleta Chuko Woreda, Sidama Zone, Southern Ethiopia
(Hawassa University College of Agriculture, 2020) AYELE RODAMO BACHO
The study was conducted in midland and lowland agroecologies of Aleta Chuko Woreda with the aim of assessing chicken management practices and compares egg production and egg quality parameters of the newly introduced Sasso chicken breed and that of local chicken. A total of 174 households rearing indigenous and Sasso chicken for at least three years were selected for the survey work based on systematic random sampling method. Three hundred eggs from the two agroecologies, (150 eggs from each agroecology, 75 eggs each from Sasso and local chicken from one agroecology) were collected from 6 Kebeles (3 Kebeles in one agroecology) and tested in Hawassa University poultry laboratory for its external and internal quality traits. Two-way ANOVA was used to evaluate the effects of the two breeds and the two agroecologies using SPSS version 20. From the respondents, 21.8% of the sampled households were female headed. The average number of chickens per households was 4.3. The current chicken breed composition in the study woreda was 62%, and 38% of local and Sasso respectively. The average age of local and Sasso chicken at first egg laying was 7.18and 5.14months of age, respectively. The average number of clutches per hen per year for local and Sasso chickens were 4.06 and 7.8, respectively. About 86.2% of the respondents from Sasso chicken rearers and 77% from local chicken rearers had experience of culling non productive chicken from their flock, with 79.3% of the culling Sasso chicken was caused due to sickness and 65.5% of the culling local chicken was caused by poor productivity. The overall means for egg production per hen per year for local and Sasso chicken was 52.74and 161.4, respectively. From this work, it is recommended that regular training must be given on management practices of the chicken and government should support on disease treatment mechanisms and vaccination of chickens.
