RESUMEN
The current research was undertaken to scrutinize the effect of leaf meal mixture as concentrate mixture in the ration of goats. Leaf meal mixture (LMM) was prepared using equal quantities of ten top-foliages namely Acacia nilotica, Celtis australis, Ficus palmata, Ficus religiosa, Grewia optiva, Melia azadarach, Morus alba, Quercus incana, Salix alba and Zizyphus jujube obtained from district Poonch of Jammu region in western Himalayas. The LMM prepared was substituted for 15% in the concentrate mixture being fed to the goats. The study constituted of two trials. Concentrate mixture offered to the animals was in mash and multi-nutrient block in first and second trial respectively. A total of twelve non-descript, adult male goats were selected for each trial. Goats of 0-14 months age (27.71 ± 2.96 kg live body weight) of for first trial while goats of 12-16 months age (27.02 ± 2.93 kg live weight) for second trial were divided into control and treatment groups as per randomized block design and fed ad-lib wheat straw and concentrate mixture @ (20 g/kgW0.75). No significant variation was observed (p > 0.05) in body weight, feed and DM intake among all groups in both trials. Comparable intake as well as digestibility of various nutrients like DM, OM, CP, EE, CF, NFE, NDF, ADF and TDN were found between the two groups during individual trials. There was a positive nitrogen, calcium and phosphorus balance among all experimental animals in both the trials. Serum enzymes ALT, AST and haemato-biochemical parameters like total protein, albumin, globulin, albumin: globulin and blood urea nitrogen (BUN) showed no significant differences during both trials in all groups, being within normal physiological levels. However, haemoglobin concentration was significantly higher (P < 0.05) in treatment group with respect to the control group in first trial. On the basis of current results, it can be established that leaf meal mixture can successfully be used to replace concentrate mixture up to 15% in the ration of goats without expecting any adverse impacts on their growth and overall health.
