Effect of Graded Levels of Groundnut oil Supplemented diets on Performance and Rumen Microbial Load of Uda Rams
Abstract
The trial was conducted at the Usmanu Danfodiyo University to evaluate rumen microbial population and fatty acids composition of diets supplemented with graded levels groundnut oil. The four (4) dietary treatments were; Treatment 1 (control) and. treatments 2, 3 and 4 each contained graded levels (0, 15, 30 and 45ml/kg) of groundnut oil. Results showed the presence of Butyrivibrio fibrisolvens, Aspergillus niger, Staphycoccus aureus, and Enterobacter spp in diets containing oils, while Bacillus anthracis, Staphycoccus aureus, and Enterobacter spp occurred in all diets. There was no significant difference in total fatty acid (FA), 18:00, 18:1 cis11, trans18, and 18:3 among the treatments, but 18:2 and Total c18 differed significantly. Groundnut oil supplementation improved fungal load count, but there was no variation in terms of bacteria count. Additionally, total fatty acids as a percentage of dry matter increased with increasing levels of groundnut oil. The study concluded that supplementation of groundnut oil improved Fungi load count though the results showed no variation in terms of bacterial count. The study also concluded that total fatty acids as percentage dry matter increased with increasing levels of groundnut oil. Based on these findings, it is recommended that groundnut oil be used to enhance the nutritional value of cattle feed. However, caution should be taken to ensure proper storage and handling of the oils to prevent contamination by harmful microorganisms. Further research is needed to investigate the long-term effects of groundnut oil supplementation on animal health and productivity.
