Abstract

Sixty-four Baluchi lambs about 5 months of age were divided into four groups with 16 lambs each. All the animals were grazed together. Group No.1 (G-1) was kept as control i.e. on grazing only; while group No.2 (G-2) was offered barley grain @ 200 g/head/day as supplement to grazing; Group No.3 (G-3) was offered ad-lib urea-molasses block (UMB) with 6% cement and group No.4 (G-4) was fed ad-lib IMB having 8% cement. These UMB were fed as supplement to grazing. Experiment lasted for 105 days (July to October) in arid zone of Baluchistan. Daily per head consumption of block No.1 was found to be 92.71 g; while that of block No.2 was observed to be 90.77 g. Growth rate (g/head/day) was found to be 10, 50, 33 and 15 in G-1, G-2, G-3 and G-4 respectively. Expenditure/kg bodyweight gain was found to be rupees 12.00, 3.64 and 7.74 for G-2, G-3 and G-4 respectively.
