The Growth Performance of Yankasa Rams Fed Gamba Grass (Andropogon Gayanus) and Various Levels of Ensiled Urea Treated Groundnut Shell Meal Supplementary Diet

Abstract

This study was carried out to investigate the feed intake, nutrient intake, and growth performance of Yankasa rams fed gamba grass (Andropogon gayanus) and various levels of ensiled urea treated groundnut shell meal supplementary diet. A total of twenty (20) growing Yankasa rams aged between 7 and 8 months with an average body weight of 11.50 kg were used for this experiment. Five treatment groups were established, with varying levels of UTGSM supplementary diet (0%, 5%, 10%, 15%, and 20%). Parameters such as organic matter, crude protein, fiber, ether extract, ash, NFE (nitrogen-free extract), concentrate, and forage intake were measured. Average total weight gain and average daily weight gain were also determined. The results showed significant variations in nutrient intake among the treatment groups. The results showed that animals on T5 with 20% UTGSM inclusion in their supplementary diet had the highest feed intake, nutrients intake and growth performance compared to the other treatments. It was concluded that 20% level of UTGSM inclusion could replace maize offal 100% in the supplementary diet of Yankasa rams to improved feed and nutrients intake, and growth performance. It was recommended that livestock producers can incorporate up to 20% of UTGSM into small ruminants feed in order to reduce the cost of production especially during the dry season.
