The study was carried out to evaluate the effects of feeding locust bean (Parkia biglobosa) seed at graded levels on the carcass characteristics of “broilers”. Two hundred and forty broilers were used which were randomly allotted to four treatment groups, each replicated four times in a completely randomized design. The diets contained 0% level of LBSM which served as experimental control, while other three diets contained 5, 10, and 15% levels of LBSM. The experiment was divided into two phases (starter and finisher) each of which lasted for 28 days. Carcass weight and dressing percentage were not significantly influenced (P>0.05) by the experimental diet but live weight was significantly influenced (P<0.05) by LBSM. Only the back weight was significantly affected (P<0.05) by the test diet among the prime cuts. Significant difference (P<0.05) were also observed in organs weight except the abdominal fat. Analysis of variance (ANOVA) was used to determine significant difference between treatment groups in term of performance parameters. Where significant difference existed, Duncan’s multiple range test was used to separate the means. Data analysis was carried out using (SPSS, 2013version 20.0). It is concluded that LBSM is safe for feeding broilers and can be included in the diet at starter and finisher phase at (5-15% - 10 and 15%) inclusion levels respectively without any deleterious effect on the growth performance.

A field experiment was conducted during the 2016 and 2017 rainy seasons at Centre for Agriculture and Pastoral Research (CAPAR) of the Usmanu Danfodiyo University Sokoto, Nigeria to study the effect of nitrogen fertilizer and inter-row spacing on Leave length and Leave width of Rhodes grass as indices of growth. A factorial combination of five fertilizer levels (0, 100, 120, 140 and 160 kgNha-1) and three inter row spacing (30, 50 and 70 cm) were used, making fifteen treatments combinations, which were laid out in a RCBD replicated four times. Determination of leave length and leave width was done at 3, 6, 9 and 12WAS using a meter rule. The data obtained were statistically analyzed by using analysis of variance (ANOVA), using the GenStat 64-bit Release 17.1 (software) to elucidate the valid information from the data. The result revealed that, application of 160 KgNha-1 generally produced plants with longer and broader (P<0.05) leaves compared to the rest of the treatments, however there was generally significant (P>0.05) effect of inter row spacing in both 2016, 2017 and the years combined, inter-row spacing of 70 cm showed superiority amongst the treatments in the leaves length and leave width parameters investigated as compared to 50 and 30 cm spacings.

The study was carried out to evaluate the effect of feeding locust bean (Parkia Biglobosa) seed meal (LBSM) at graded levels on the performance of broilers. Two hundred and forty broilers were used which were randomly allotted to four treatment groups, each replicated four times in a completely randomized design. The diets contained 0% level of LBSM which served as the control, while other three diets contained 5, 10 and 15% levels of LBSM. The experiment lasted for 28days. Significant differences of (P<0.05) were observed in feed intake (g/b/d) water intake ml/b/d, final body weight (g/b), body weight gain (g/b) averaged daily gain (g/b/d) and feed conversion ratio (FCR). While no significant effect of locust bean seed meal (LBSM) in broilers diets provide effective mechanism for better performance. But live weight was significantly influenced (P<0.05) by LBSM. Analysis of variance (ANOVA) was used to determine significant difference between treatment groups in term of performance parameters. Where significant difference existed, Duncan’s multiple range test was applied to separate the means. Data analysis was carried out using (SPSS (SPSS, 2013version 20.0).It is concluded that LBSM can be included in the diet of broilers at starter phase from 5-15% inclusion levels while at finisher phase, diets containing 10 and 15% level of inclusion would be used for better performance without any deleterious effect on the growth performance. It could be recommended that, diets containing 10 and 15% LBSM level of inclusion would be used for better performance and economic benefit with better feed conversion ratio.
