ABSTRACT
To lessen the detrimental effects on ruminant growth and health during the dry season, several combinations of non-traditional diets are being researched. In order to better understand the growth, haematology, and serum biochemical indicators of West African Dwarf (WAD) ram lambs, a study was designed that included cassava peels ensiled with urea (UTCP) and graded amounts of Gliricidia sepium fodder (GSF). Sixteen yearling WAD rams with an average weight of 12±1 kg was randomly assigned into four treatments (T1, T2, T3, and T4) in a ten-week trial. The rams assigned to T2, T3, and T4 were fed 90% UTCP+10% GSF, 80% UTCP+20% GSF, and 70% UTCP+30% GSF, in that order while T1 served as the control group. The data did not show a statistically significant difference (p>0.05) among any of the treatments in feed intake. The experimental animals’ final body weight was significantly low in T1 (p<0.05). Although the total weight and average weight gain showed similarities (p>0.05) across different levels of GSF inclusions in the experimental diets, there was a significant increase (p<0.05) in treated groups (T2-T4) as compared to control group (T1). The FCR of the control diet was the poorest (p>0.05) at 8.09, whereas the FCRs of T2 (6.70), T3 (6.89), and T4 (6.56) did not vary (p>0.05). The results also showed that the diets had no significant effect on all the haematological parameters studied except lymphocyte and eosinophil. Lymphocyte was lowest (p<0.05) in T2 (23.33±1.53%) compared to similar (p>0.05) values obtained in the other treatments whereas eosinophil was highest (p<0.05) in T1 (3.00+0.00%) compared to the similar (p>0.05) values obtained in T2, T3, and T4. Additionally, the serum biochemical indices demonstrated typical immune reactions (p<0.05) to the test substances in total protein, globulin, total cholesterol, triglycerides, aspartate aminotransferase, and alkaline phosphatase. In all these except alkaline phosphatase, the animals fed 30% GSF and 70% UTCP (T4) fared better than the animals on other treatments. Therefore, when the grasses in tropical regions dry up during the prolonged dry season, sheep can survive on urea-treated cassava peels and Gliricidia sepium fodder.
