Therefore, the utilization of agricultural by product is one of the safe ways to attempt this goal. For this end, a study on the level of incorporation of cocoa pod husk on growth performance, haematological and biochemical parameters were carried out. A total of 80 young rabbits composed of 40 males and 40 females with an average weight of 824.30 ± 53.8 g and 826.09 ± 40.61g respectively. There were randomly assigned to 5 experimental rations in a complete randomized designed with 8 rabbits per treatment and each rabbit served as experimental unit. From the control ration R (0-);0% cocoa pod husks and R (0+);20% of untreated hulls, 3 other rations of which three (R1, R2, R3) were formulated with respectively 20%, 25%, and 30% husks treated with ash from bean haulms at concentrations of 12.5 kg/100 litters of water. The results revealed that the initial weight, feed consumption, feed conversion ratio, were not significantly affected (p > 0.05) by the different treatments. However, total weight gain, daily weight gains and final body weight of rabbit fed R1 ration were significantly (p < 0.05) higher (1973.77;23.49;2794.60 g respectively) as compare to other treatment irrespective of sex. Analysis of variance generally revealed a significant effect (p < 0.05) on fasting body weight (2447.43;2476.22;2687.99;2512.52;2425.89 g respectively for rations R0-, R0+, R1, R2 and R3), carcass weight (1270.84 g) and carcass yield (52.37%) was lower for animals feed R3 ration regardless of sex. On the other hand, no significant difference (P > 0.05) was observed in the relative weights of some parts, organs and those of the abdominal fat of the rabbits. Similarly, no significant difference (P > 0.05) was observed for haematological and biochemical parameters studied. Cocoa pod husks treated at 12.5% with bean haulm ash extracts can be incorporated up to 20% - 25% to improve growth performance of rabbits without any negative effect on their health.展开更多

The experiment was laid out in split block design with varieties as main plots (Lady Finger “LF”, LD88 and Okele (local cultivar)) and different nitrogen sources as sub plots (Urea (108.7 kgN/ha), poultry manure (PM) (3.01 t/ha = 108.7 kgN/ha) and cow dung (CWD) (3.83 t/ha = 108.7 kgN/ha). The treatment combinations were as follows LD88 + Urea, LD88 + PM, LD88 + CWD, LF + Urea, LF + PM and LF + CWD, Okele + Urea (108.7 kg/ha), Okele + PM and Okele + CWD. Growth parameters determined were plant height (cm), leafarea (cm2), number of leaves produced, stem girth (cm), internode length (cm) and days to 50% flowering and podding. Flower characters taken were number of flowers produced per plant, number of flowers aborted per plant, and number of pods produced per plant. Yield characters determined were individual pod weight (g), pod length (cm), pod diameter (cm) and pod yield (t/ha). The data collected were subjected to analysis of variance (ANOVA) and means compared using the least significant difference (LSD) at a probability level of 5%. Urea application and poultry manure had significantly different effects compared with cow dung treated plots for the parameters of growth and yield. Highest mean value was observed with urea application. This was followed by poultry manure application. The cultivar Lady’s finger performed better according to the data for number of pods and fresh pod weight. This was followed by the LD88 cultivars. Okra grew taller and had bigger stem girth, greater number of leaves, larger leaf area and higher number of pods and fresh pod weight with urea application. Cultivar Lady’s finger performed better than the other cultivars in most measured parameters. It is therefore recommended that lady finger should be grown by farmers in the study area with their soil amended with urea fertilizer in the study area.展开更多
