Abstract

The feeding value of mixtures of Panicum maximum and cowpea shell were investigated with Red Sokoto goats, by feeding with Panicum maximum hay at different ratios of 80:20, 70:30, 60:40 and 50:50, in 4 x 4 Latin square designs. The study lasted for 105 days, during which feed intake, weight gain, digestibility and nitrogen utilization were monitored in 20 goats using completely randomized design. Significant (P<0.05) difference in basal diet intake was observed, with animals fed 50:50 diet (166.88g/day) higher than 60:40 (151.25g/day) which was statistically higher than 70:30 and 80:20. Similar trend was also observed in total intake and dry matter intake. The crude protein (CP) digestibility for 60:40 (61.75gday) was significantly (P<0.05) higher than 50:50 (58.06g/day) and 70:30 (56.14g/day) which were statistically similar and higher than 80:20 (54.92g/day), which recorded least value. The crude fibre (CF) digestibility statistically (p<0.05) decreased across treatments from 50:50 (66.82g/) to 80:20 (59.18 and 58.77g/day). Nitrogen intake was significantly (P<0.05) affected by dietary treatment, with 50:50 having higher N intake (6.91g/day), which decrease with decrease panicum in the basal diet. N balance were statistically (P<0.05) higher and similar for 50:50 and 40:60 (3.56 and 3.72g/day, respectively), which were followed by 70:30 (3.04g/day) and least was in 80:20 (2.59g/day). Both nitrogen observed and nitrogen retained as percent of intake for 60:40 were significantly (P<0.05) higher as compared to all other treatments with 80:20 recording the least value. It can be concluded that feeding 60:40 ration of P. maximum to cowpea shell gave the best result in terms of nutrient intake, digestibility and nitrogen balance in Red Sokoto bucks.In conclusion Panicum cowpea shell mixture at 60:40 can be fed to red Sokoto Bucks without adverse effect on intake, digestibility and nitrogen balance.It can be recommended that small scale farmers should include 60:40 of Panicum maximum: cowpea shell in feeding their animals because of its availability, affordability and nutritive value.
