This study was aimed at determining the productivityof lamb from mating between Garut ewes and Dorper rams. The animalsused were 108 sheep. A total of 98 headsof Garutewes were randomly divided into two groups;the first group was mated with Dorper rams(5 heads),while the second group was mated withGarut rams (5 heads)as a controlgroup. The data observed were birth weight, weaning weight, average daily gain (ADG), reproduction index (RI), and productivity index (PI). Thedata were analyzed with an independent sample T-Test. Birth weight, weaning weight, and ADG of Garut and Dorpercrossbred lambs were 2.20±0.54 and 2.60±0.71 kg; 14.91±3.57 and 16.27±3.69 kg; and 90.21±32.11 and 119.12±42.64 g/day, respectively. Pre-weaning growthof Dorper-crossed lambs washigher (P<0.05) than those of Garut lambs. TheRIand PI of Garutewesmated with Garut and Dorper rams were 3.15±1.38 and 2.87±1.33 head/year; and 32, 10±15.53 and 38.91±21.00 kg/year, respectively. The PI of ewes mated with Dorper rams was higher (P<0.05) than that of Garut ewesmated with Garut rams. It is concluded that the cross of the Garut eweswith the Dorper rams improved productivity by increasing the pre-weaning growth of the lambs. |
