Effect of feeding different proportions of groundnut haulms (Arachis hypogaea) and cluster bean straw (Cyamopsis tetragonoloba) on nutrient utilisation and serum biochemical parameters in dromedary camels.

The effect of feeding different proportions of groundnut haulms (Arachis hypogaea) and cluster bean straw (Cyamopsis tetragonoloba) on nutrient digestibility, nutritive value, nutrient intake and serum biochemical parameters was studied using nine male dromedary camels of Bikaneri breeds (637.5 kg average body weight; 8-9 years of age). Groundnut haulms (GNH) and cluster bean straw (CBS) were fed in one of three ratios, 75:25, 50:50 and 25:75 in treatments T(1), T(2) and T(3), respectively. In all treatments, concentrate mixture was fed as per requirement of the camels. The groundnut haulms were more nutritive as compared to the cluster bean straw. The nutrient digestibility of dry matter, organic matter, crude protein (CP), crude fibre and acid detergent fibre was better in T(1) than T(2) and T(3). Likewise, the CP, digestible crude protein and total digestible nutrient contents were significantly higher in T(1) followed by T(2) and T(3). There was non-significant affect on average daily gain of camels. However, dry matter intake, digestible crude protein intake and total digestible nutrients were better in T(1) as compared to T(2) and T(3). The total water intake per kilogram of dry matter intake (litres) was 2.98, 2.89 and 2.68, respectively, in T(1), T(2) and T(3). The camels in all the treatments were in positive nitrogen, calcium and phosphorus balance. The treatments had a significant effect on serum biochemical parameters like glucose, cholesterol, aspartate transaminase and creatinine. The results may conclude that feeding of higher proportion of groundnut haulms as compared to cluster bean straw has pronounced improvement in nutritional utilisation by the camels.
