This study was conducted at the College of Veterinary Medicine and Animal Production Farm, Sudan University, at Hillat Kuku, in Sudan. To investigate the effect of feeding different levels of pigeon peas and season on some carcass characteristics of 40 male Nubian goat kids, in replacement of groundnut cakes. Two experiments were conducted, both for 10 weeks, during winter and summer season. Results showed that most of the carcass characteristics were influenced (P<0.05) by dietary treatments

... d season. All parameters values were high for feeding 20% pigeon peas in the winter season. The results have shown that, the highest mean values were 45.77 d ± 0.63,2.42 d ± 0.91 and54.09 b ± 3.41for the carcass yield, shrinkage, and muscles percentage respectively. The lowest values were 44.75%, 6.02% and53.21% for the above parameters respectively for the control groups, fed zero% C.cajan, in the summer season. Bone content, muscle bone ratio, and fat percentage varied significantly with both feed and season, being the highest values were 26.62%, 2.05%, and17.11% respectively, obtained by groups fed 20% pigeon peas in the winter season, while the lowest values were 22.11%, 1.97% and 11.85 for the above parameters respectively obtained by the control groups, fed zero% pigeon peas, in the summer season. It is clear that pigeon peas seeds can be added to ruminants feed up to20% of the ration, without any side effects. On all parameters tested, it was superior to groundnut cakes, especially during the winter season. It was concluded that pigeon pea seeds can replace groundnut cakes in feeding ruminants.
