  The aim of the study was to assess the effect of soymilk on spermatozoa and its use as an extender. Twelve Yankasa rams between 12-48 months old were used for the study. The semen was collected with an electroejaculator, evaluated for sperm concentration and percent sperm motility, live spermatozoa and sperm abnormalities. The best semen samples were randomly assigned to four extenders (Cornell University Extender, CUE), whole milk glycerol extender, soymilk glycerol extender and soymilk-CUE). These samples were stored for 4 days at 5°C and analyzed for semen quality. The result shows the differences between the extenders were not significant for the initial and final percent sperm motility, except for soymilk. There were no significant differences in the extenders for initial and final percent live-spermatozoa except in the spermatozoa extended in soymilk extenders. Out of the four extenders tested for semen preservation in this study, soymilk extender and soymilk-CUE least supported sperm motility and liveability, although soymilk-CUE was better than soymilk. The problem of the poor performance of the soymilk and soymilk-CUE could be due to the concentration of soybean fluid content and/or the antinutritional factors probably present in the soymilk due to the mode of preparation. Further studies are suggested along these lines.

  A study was conducted on 120 day-old broiler chicks fed graded levels of Alphamune G (0.00, 0.04, 0.05 and 0.06%) in a Completely Randomized Design. The experiment was conducted for 8 weeks. Feed intake and weight gain were significantly influenced (p<0.05) by the inclusion levels of Alphamune G. Broiler chicks fed 0.04% inclusion level of Alphamune G had the highest weight gain (35.85 g) with the least feed to gain ratio (2.36). Carcass characteristics also revealed broiler chicks on 0.04% inclusion of Alphamune G to be significantly better than the control diet in weight of keel, drumstick and thigh (20.65, 13.79 and 12.22 g, respectively). Heamatological values did not show any significant effect (p>0.05) except in PCV value where 0.04% inclusion of Alphamune had significantly lower value (31.00%). However all values fall within the normal range. Histological studies revealed morphological changes in broilers fed Alphamune G supplemented diet viz- a-viz the control diet. Alphamune G at 0.04% inclusion in diets of broilers may help improve performance.

  A study was conducted to determine the response of day-old cockerel chicks to graded levels of Alphamune G (0.00, 0.04, 0.05 and 0.06%). The experiment which was conducted for 8 weeks employed a completely randomized design. Feed intake and nutrient retention were not significantly influenced (p>0.05) by dietary inclusion levels of Alphamune G. However, weight gain and feed to gain ratio were significantly improved (p<0.05) for cockerel chicks fed 0.06% inclusion level when compared with the control. The values were 7.78 and 4.58 g/bird/week, respectively. Haematology and serum indices did not show any significant effect as a result of the graded levels of dietary Alphamune G. Histological characteristics revealed slight morphological changes in specific organs of birds fed Alphamune G supplemented diet vis-a viz the control diet. Inclusion of Alphamune G at 0.06% in the diets of cockerel chicks gave the best performance.

  The study analyzed the economics of using cocoa bean shell (cbs) as feed supplement in rabbit production. Data used for this study was collected from an experimental study of performance of rabbits fed graded levels of various treatments of CBS as feed supplement. Gross margin and dominance analysis were used to analyze the data. The study showed that untreated CBS can be used economically at 100g/kg inclusion in rabbit feed while hot Water treated CBS (WCBS) can be included up to 200 g/kg in rabbit feed. The study recommends the use of hot water treatment of CBS at 200 g/kg inclusion for optimum profitability of rabbit production.
