An experiment was conducted to evaluate the effects of feeding Cassia obtusifolia leaf meal on growth performance and carcass characteristics of broiler Chickens. Two hundred (200) unsexed day old Marshall Broiler chicks were used for the study. Five diets were formulated such that Cassia obtusifolia leaf meal were used at 0%, 3%, 6%, 9% and 12% designated as treatments T1, T2, T3, T4 and T5 respectively. The chicks were weighed and randomly allocated to five dietary treatments replicated four times with ten birds per replicate in completely randomized design. The proximate composition of Cassia obtusifolia showed it contains 93.51% dry matter, 25.44% crude protein, 19.14%, crude fibre, 12.17% ash, 4.06% ether extract and 38.19% nitrogen free extract. The leaf meal also contains saponin (6.26%), phytate (2.97%), tannins (4.52%) and oxalates (2.37%). The result of growth parameters measured were significantly different (P<0.05) except, total feed intake and average daily feed intake. Similarly, live weight, plucked weight, eviscerated weight, carcass weight and dressing percentage did not show any significant difference among treatment groups. The result of the internal organs evaluated showed variation in the weights of pancreas, large and small intestines across the treatments. It was concluded from the results obtained that COLM can be included up to 9% in broiler chickens' diet without adverse effect on the growth performance, carcass and internal organs characteristics.

This study evaluated the growth performance of weaner rabbits fed diets containing sundried soybean milk residue meal (SSMR) at five levels of inclusion. Forty weaner rabbit with an average initial weight of 520±1.04g arranged in a completely randomized design (CRD) were used. SSMR was used at 0, 25, 50, 75 and 100% levels to replace soya bean meal. The result of the growth performance showed progressive increase in parameter evaluated as the level of SSMR increases in the diets. Rabbits fed (100% SSMR) recorded significant higher final body weight 1351.73g which was similar to rabbits fed 25, 50 and 75% SSMR while those on T1 (0% SSMR) had the least value of 1194.50g. However, carcass characteristics and internal organ weights measurements were also not influenced by the treatment diets. It was therefore concluded that 100% SSMR can be used in compounding weaner rabbits without deleterious effect on growth performance, carcass characteristics and internal organ weights.     Cette étude a évalué le rendement de croissance des lapins sevrés nourris selon des régimes contenant des résidus de lait de soja séchés au soleil (RSSS) à cinq niveaux d'inclusion. Quarante lapins sevrés d'un poids initial moyen de 520±1,04 g disposés dans un modèle complètement randomisé (CRD) ont été utilisés. SSMR a été employé aux niveaux de 0, 25, 50, 75 et 100% pour remplacer le repas de haricot de soja. Le résultat de la performance de croissance a montré l'augmentation progressive du paramètre évalué comme le niveau des augmentations de SSMR dans les régimes. Les lapins nourris (100% SSMR) ont enregistré un poids corporel final plus élevé significatif 1351.73g qui était similaire aux lapins nourris 25, 50 et 75% SSMR tandis que ceux sur T1 (0% SSMR) avaient la valeur la moins élevée de 1194.50g. Cependant, les caractéristiques de carcasse et les mesures internes de poids  d'organe n'ont pas non plus été influencées par les régimes de traitement. Il a donc été conclu que 100% SSMR peut être utilisé dans la composition des lapins sevrés sans aucun effet sur la performance de croissance, les caractéristiques de la carcasse et le poids interne des organes.
