  An analytical study was conducted on food animals slaughter figures for Ebonyi State from 2000 to 2005 and results of analysis of the trends in volume and magnitude showed that, in terms of number, cattle was the highest slaughtered animal specie followed by goats, pigs and donkeys. The least were sheep and horses. The prevalence of foetal wastage among food animals slaughtered in the State between 2000 to 2005 revealed that a total number of 9,780 cattle (9.15%), 876 sheep (41.32%), 6170 goats (64.12%), 1183 donkeys (64.20%), 499 Horse (44.94%) and 1203 pigs (36.14%) slaughtered in the state were pregnant. This translates to a ratio of 1 in every 11 cows, 1 in every 2.5 ewes, 1 in every 1.5 does and donkeys, 1 in every 2.2. mares and 1 in every 2.7 sows. The slaughtering of pregnant animals was significantly (p< 0.05) high during the dry seasons of November through April and festival periods reflecting the high levels of female animals slaughtered during these periods. Though the trend in the number of pregnant animals were not consistent, there was no significant differences observed among the food animals across the years even when the figures ranged widely (51 to 87 for cattle, 13 to 49 for sheep, 250 to 600 for goats, 36 to 72 for donkeys, 8 to 18 for horse and 8 to 16 for pigs), respectively. Percentage foetal wastage among the goats and donkeys was constantly high across seasons and years. In view of the high level of foetal wastage among food animals in the state, policy efforts must concentrate on instituting routine veterinary checks at control posts and abattoirs. Above all, producers and middle men must be better informed about the seasonal breeding patterns of food animals in order to avoid disposing of them during the calving season.

  Data on 1010 Nigeria sahelian goat kids accumulated for nine years in the Small Ruminant and Multiplication Research Unit, Department of Animal Production, Ebonyi State University , Nigeria, were analyzed for the estimation of genetic parameters of growth traits. The heritability, phenotypic and genotypic, correlations were evaluated for birth, 3, 12 and 18 months live weights. The year of rearing, sex and parity had significant effects except birth type (p<0.05) in all the different periods of growth from birth until 18 months of age except birth type which was neutralized at 18 months of age. Sex effects continued at 18 months with males displaying superiority (p<0. 05) over the females. Live weights traits had high heritability and the correlation was positive and high. This study further suggests that selection can be adopted as a technique for improving weaning, yearling and maturity weight by selection for heavier kids from weaning age.

  In Abakaliki and Nigeria in general, goats are kept primarily for meat yield, so production traits of interest are the number of young weaned per breeding female per year and their growth rate. The assessment of the reproductive performance and growth of cross bred local (RSG F1) an adapted breeds of goats in Nigeria provide vital information to understanding its productive potentials. Reproduction data of 1,1304 kids from 510 does were collected for 9 years in the Small Ruminants Research and Multiplication u it of the Department of Animal Production, Enugu State University, of Science and Technology, Abakaliki Campus, Nigeria. The reproductive performance evaluated included prolificacy, fertility, kidding, post-weaning growth, mortality and gestation length. Growth traits studied were birth and 72 weeks of live weights and average daily gains. Statistical analysis showed significant effects (p<0.05) due to season of rearing with early and late rainy displaying superior values over other seasons on live weights. Sex of kids and types of birth had significant effects (p>0.05) on birth and 72 weeks live weights with males, singles and twins displaying superiority over females and triplets kids, respectively. Average daily gains were significantly affected by sex, type of birth and season of rearing. The overall mean for gestation days was 131.210.73 and was affected by season, sex and type of birth. Single birth males, early and late rainy seasons recoded more number of days of gestation than others. Conclusively the crossbred Nigeria Red Sokoto goats (RSG F1) have high reproductive performance under certain season of rearing with the males having higher meat yield potentials.
