| Abstract | ||
| This study was conducted to investigate the effect of feeding supplemental urea - molasses multinutrient block (UMMB) during late pregnancy and lactation on lamb performance of a nomadic sheep flock in Saveh area. Sixty ewes of Zandi sheep were divided in to two similar groups including control and experimental group. The control group was fed only with range feed only in nomadic manner. Each ewe in the experimental group received 100 grams of nutritional supplementary feed block per day in addition to grazing in rangelands. Results indicated that mean birth weight of lambs in the experimental group was higher than the control group (4.4 kg vs. 3.8kg). There were significant differences among two groups for lambsweaning weight (P<0.05). The weaning weight of lambs in the experimental group was higher than the control group (20.1 vs.17.2 kg). Average daily gain of lambs from birth to 90 days age in the control and experimental groups were 148.8 and 173.4 g/day , respectively which was higher (p<0.05) in the experimental group. In general, the results of this study showed that daily feeding of 100 g Multin-utrient block in ewe during the last two months of pregnancy and the first three months of lactation improved the productivity performance of nomadic sheep flock in Saveh region. | ||
