ABSTRACT: The utilization of grain legumes such as Leucaena leucocephala by the feed industry is limited because of uncertainty about their nutritional quality. Although the analyzed total amino acid and energy contents of many grain legumes are quite similar, their protein qualities and metabolizable energy values are quite variable. Leucaena leucocephala seeds were analyzed for chemical composition and amino acids profile. The analyzed nutrient composition indicated that leucaena seeds are potential source of protein and energy. The protein content was 31.1% and the calculated metabolizable energy of the seeds was 2573.26 kcal/kg. Amino acids profile of leucaena seeds were 1.39% lysine%, 0.36% methionine, 0.35% cystine, 2.62% arginine, 4.63% glutamic acid, 0.87% threonine, 1.38% glycine, 1.11% alanine, 1.11% valine, 0.93% isoleucine, 1.81% leucine and 0.71% methionine + cystine. Antinutritional Factors (ANFs) were 0.75% tannin and 697.50 mg/100g phytate. Leucaena seed was incorporated at 0, 3, 6, 9 and 12% in broiler chicks' diets. One hundred twenty one-day old unsexed broilers (Ross 308) were used. The performance revealed that, the overall feed intake and body weight gain were significantly (p < 0.01) depressed with the inclusion of 6, 9 and 12% leucaena seeds in the diet.

ABSTRACT: This experiment was conducted to assess the effect of feeding different processed pigeon pea seeds on broilers performance. Four isocaloric and iso-nitrogenous diets containing (10%) of soaked pigeon pea seeds, decorticated with added enzyme (multi enzymes with high content of pentosanase), decorticated roasted and control diet were formulated. Parameters measured weekly were feed intake, body weight gain and Feed Conversion Ratio (FCR). Overall body weight, hot carcass weight and dressing percentage were recorded. Results revealed that inclusion of 10% soaked pigeon pea seed, decorticated with added enzyme (multi enzyme with a high content of pentosanase) and decorticated roasted had no significant (p > 0.05) effects on feed intake, weight gain, feed conversion ratio, final live body weight, hot carcass weight and dressing percentage. Inclusion of 10% processed pigeon pea seeds resulted in a similar performance of broiler chicks when compared with the control group.

ABSTRACT: The layers experiment was conducted to evaluate the effect of different levels of leucaena seed (0, 8, 16 and 24%) on 27 weeks of old laying hens. Parameters studied were egg production, external and internal quality characteristics of eggs, haematological indices and plasma constituents. Feed intake, hen-day egg production, FCR (kg feed/kg egg) and FCR (kg feed/dozens of egg) were depressed with the inclusion of leucaena seeds. Thereafter, birds were placed on control diet for two weeks, which revealed improvement of the performance except for FCR (kg feed/dozens of egg) for birds fed 24% leucaena seeds. Higher egg weight, maximum length and egg shell surface were recorded for birds fed 16% leucaena seeds compared to the others. Maximum width, shell weight and shell% were reduced for birds fed 24% leucaena seeds. Internal quality characteristics of eggs were not significantly affected by the dietary treatments except albumin weight, albumin%, yolk index and yolk color score. Yolk color score consistently increased with the inclusion of leucaena seeds.

ABSTRACT: The core objective of this study was to assess the effects of different dietary Leucaena leucocephala seed on the performance and some blood parameters in broiler chick. Seeds were included at 0, 3, 6, 9 and 12% in the diet of one hundred twenty one-day-old unsexed broiler chicks. The results showed that, feed intake, body weight gain and PER were significantly (p < 0.01) depressed with the inclusion of 6, 9 and 12% leucaena seeds in the diet. Feed intake, body weight gain and PER were negatively correlated (p < 0.05) with levels of inclusion of leucaena seeds. However, overall FCR, haematological parameters, plasma albumin, glucose and mortality rate were not influenced (p > 0.05) by dietary treatments. Inclusion of dietary leucaena significantly decreased plasma Ca, Na, total protein and cholesterol. While plasma Glutamic oxaloacetic transaminase GOT, alkaline phosphatase ALP and uric acid were increased with the increase in levels of leucaena in the broiler diets.

ABSTRACT: In the current experiment, Leucaena leucocephala seeds were subjected to three treatments (soaking, roasting and supplementation with 40mg/Kg ferrous oxide). Then treated and untreated leucaena seeds were incorporated in boiler diets at 0, 6 and 12%. Soaking and roasting of the seeds reduced phytate, whereas tannin was not significantly affected. Feed intake and weight gain were significantly (p ≤ 0.05) reduced with the inclusion of 12% untreated leucaena seed, 12% soaked or 12% roasted leucaena seeds. However, feeding diets that supplemented with ferrous had no negative effect on feed intake and weight gain compared with control. Dietary treatments did not affect haematological parameters, plasma GOT ALP, K, inorganic phosphorus (Pi), total protein, albumin, globulin, cholesterol, uric acid and tibia P. Plasma glucose for birds fed leucaena seed diets was not significantly different as compared with those fed the control diet.
