Résumé
To Study on production performance of Magra lamb under different supplementary Feeding in Arid Zone an experiment was conducted by taking 24 Magra lambs of same age (average 5.5 months) and uniform conformation in a randomized block design and according to 8 lambs in each divided in three group, T1 group (Control group) which was kept exclusively on grazing, T2 group (Grazing + Multi-Nutrient Mixture feed group) and T3 group (Grazing + Concentrate pellet feed group). The Multi-Nutrient Mixture of 19.6 percent CP was formulated on dry matter basis using ingredients Wheat Bran 40 parts, Guar Khorma 10 parts, Molasses 40.5 parts, Urea 4.5 parts, Mineral Mixture 3 parts and Salt 2 part. In T3 group were offered pelleted concentrate feed (Saras gold) purchase from Dairy plant having 19.8% CP was fed to meet the requirement of nutrient. The effect of supplementary feed were made by determination of body weight gain, average daily gain, feed conversion ratio and body conformation, haemato-biochemical parameters, wool characteristics and lastly economics of the two supplementary feed were worked out. 115 Highly significant effect (P<0.01) of treatment were observed on body weight gain, average daily gain, feed conversion ratio, blood urea and significant effect (P<0.05) observed on blood protein, fibre diameter, medullation, hairy, pure. Whereas effect on heart girth, length, height, abdominal girth, haemoglobin, blood cholesterol and blood glucose were revealed statically non-significant. The results obtained from the comparative study of two supplementary feeding were beneficial rather than grazing and that supplementary feeds provide uniform supply of nutrients at regular intervals which helps to improve growth performance, blood protein and urea and fibre metrology. The cost of feed per kg additional weight gain was higher on concentrate pellet than Multi-Nutrient mixture while considering the cost of grazing is zero, indicating that Multi Nutrient mixture is economical than concentrate pellet feed under semi-intensive system of management and that Multi-Nutrient mixture can become a feasible and economical proposition for sheep production in arid zone.
