Morphological and Morphometric Characterization of Indigenous Goat in Their Native Environment in West Omo and Bench-Sheko Zone, Southwestern Ethiopia Bayou, Eliyas This study was conducted on Morphological and Morph metric characterization of indigenous goat in West Omo and Bench-Sheko zone of in their native environment. About 660 goats were taken for body measurements of both sexes from 1PPI to 4PPI. Sex, districts and age class effect were considered in this study. The main frequently observed coat color patterns of goats were patchy and plain in Meanit Goldiya and Guraferda area, respectively. The main dominantly observed coat color type were white dominate with black for both sexes in Meanit Goldiya and brown for female and white for male goats were dominantly observed coat color in Guraferda area. Majority of goats had concave head profile in both districts. Body weight of goats increased as the age increased from 1pair of permanent incisor (PPI) to 4 PPI in the studied areas. Body weight and all the body measurements were significantly (P<0.01) affected by age group. Average body weight of males at age of 1PPI, 2PPI, 3PPI and 4PPI were 23.4±0.29, 26.4±0.81, 31.6±0.99 and 34.0±0.55kg, respectively. The corresponding values for female goats were 20.2±0.12, 23.6±0.44, 26.2±0.18and 30.0±0.16kg, respectively. Therefore, the present study suggests that indigenous goat population might possess useful genetic potential for improving productivity under extensive feeding-based production system. Similarly, morphological and phonotypical variations have been observed between the indigenous goat populations; hence a profoundly molecular evaluation is needed to show the level of genetic differentiation and relation between them

Effect of estrus synchronization with prostaglandin (PGF2α) hormone on reproductive performances of Bonga sheep ewes flushed with different local forages in Kaffa zone, Ethiopi Begna, REGASSA; Masho, Worku; Bayou, Eliyas This study was conducted in Adiyo and Telo districts of Kaffa zone, aiming to evaluate the performances of Bonga sheep and their response to estrus synchronization flushed with indigenous feeds under different management conditions. Eight representative kebeles were purposively selected based on CBBPs and sheep population presence. From each kebele, the farmers with ewes were registered and 200 respondents were randomly assigned using Kothari, (2004). In the current study LI 9.4 ± 0.18 months, DO 20.2 ± 0.13 days and LS 1.4 ± 0.04 were obtained and LI was shorter (8.5 ± 0.22 months) in CBBP than 10.5 ± 0.28 months in non-participants. The BWT, WWT and 6 MWT were 3.8 ± 0.06, 16.0 ± 0.10 and 27.8 ± 0.33 kg and the values for PrWDG and PoWDG were136.0 gm/day and 133.0 ± 0.02 gm/day respectively. In the experimental study the onset and duration of estrus were 45.9 ± 2, 43.1 ± 2.37 and 48.0 ± 2.61; 45.6 ± 1.55 hours in short and long flushed ewes accordingly. Estrus response, conception, lambing rate and LS were 68, 70.59, 72.22%, 1.38 and 84, 83.3, 90% and 1.42 for short and long flushing sequentially. Flushing with indigenous feeds in long-term flushing presented better results regarding the positive manifestation of estrus, conception lambing rate, liter size and onset, and duration of estrus. Therefore, long term (28 days) flushing was an effective strategy to increase ewes’ reproductive performance. Keywords: Bonga sheep, Ewe flushing, Reproductive performance, Indigenous feed

Evaluation of flock structure and performances of Bonga sheep under extensive management conditions in Kaffa Zone, South Western Ethiopia Masho, Worku; Begna, REGASSA; Bayou, Eliyas this study was conducted in Adiyo and telo districts of Kaffa Zone, south Western Peoples regional state (sWePrs) of ethiopia with the aim of evaluating the performance of bonga sheep under farmer’s management conditions. to this end, the farmers who have ewes were registered and 200 respondents were randomly selected. the study revealed that both participant and non-participant farmers have been rearing sheep for the purpose of income generation, followed by saving, social value, meat and wealth in decreasing order. the current study also revealed that disease and parasites are the major constraints for both groups, followed by predator and shortage of fodder. lambing interval (li) was 9.4 ± 0.18 months, days open (dO) were 20.2 ± 0.13 days and liter size (ls) was 1.4 ± 0.04, and lambing interval (li) was shorter (8.5 ± 0.22 months) in community based breeding program (cbbP) participants than in non-participants (10.5 ± 0.28 months). the birth, weaning and six month weight were 3.8 ± 0.06, 16.0 ± 0.10 and 27.8 ± 0.33 kg. the preweaning average daily weight gain and postweaning average daily weight gain were 136.0 and 133.0 ± 0.02 g/day respectively. both participants and non-participants’ reproductive and growth performances have shown a remarkable progression. in conclusion, engagement of farmer in cbbP improved lambing interval, birth weight, weaning weight, six month weight, pre-weaning weight average daily gain, and post weaning average daily gain of bonga sheep. Hence, cbbP strategy is likely to be important to attain the designed benefit from sheep production in the area.

Productive and reproductive performance of indigenous chickens in Ethiopia

Productive and reproductive performance of indigenous chickens in Ethiopia MILIKIAS, MATAWORK This study reviews the productive and reproductive performance of indigenous chickens in Ethiopia with the aim of delivering summarized and synthesized information for the beneficiaries and producers. Chicken production encompasses into traditional scavenging, small and large-scale market orientated systems based on the objective of the producer, the type of inputs used and the number and types of chickens kept. In Ethiopia, indigenous chickens produces 10 to 20 eggs per clutch and 30 to 65 small eggs per hen per year in 3 to 4 clutches. Local chickens reach slaughter/market age at 8 to 12 months with 0.6 to 2.5 kg average weight at farmer management system. Indigenous chickens require long time to reach sexual maturity and takes longest time to recover reproductive cycle by local broody hen. The average mortality rate was highest and which affects both productive and reproductive performance of indigenous chickens by reducing survival rate. There were huge number of indigenous chickens existing in Ethiopia but productivity was disproportional to the number of chickens. The major constraint which affects productive and reproductive performance of indigenous chickens are diseases and predators, feed shortages, lack of training and extension services, and lack of proper marketing systems. Conclusively, lowest productive and reproductive performance
