| dc.description.abstract | Indonesian local sheep (in Indonesia reffered to as local sheep) have a unique characteristic as a animal tropic which could well adapted in low vegetation and global warming also. The aim of this study is to know the effect of age and birth type on milk yield do the relation with meat producing. Sheep that we used were local type. Local type means crossing beetwen javanese thin tailled ewe, garut and fat tailled ewe (because there are no detailed recording for many years). Ewe that we were used are 92 heads which has 78 single lamb and 14 twin lamb type. Lamb suckling weight differences technique were used to calculate milk yield of ewe. I3 (ewe third years) have given the highest milk yield 443.43 ± 102.62 g/ewe/day. In the contrary I1 (ewe first year) have gotten the lowest one which is 254.53 ± 49.67 g/ewe/day. That could be explained with the maturity stage. The maturity stage in I3 faster than I1 and I2. The second aspect is about birth type, twin type have given higher milk yield 344.95 ± 66,22 g/ewe/day than single type 413.99 ± 128,62 g/ewe/day. Higher milk yield in twin ewe could be explained with increasing of mammary secretory cell. The nutrient requirement in twin type more than single one. | id |
