| dc.description.abstract | Sheep fattening farms have recently been growing rapidly to produce better quality of sheep meat. Selection on their growth can be achieved, however production and quality of carcase should also be tested. The experiment was conducted at PT Tawakal, a sheep fattening farm located in Caringin, Bogor and Laboratory of small ruminant and large ruminant, Faculty of Animal Science, Bogor Agricultural University. One hundred and sixty nine young male sheep (less than one year old) were selected based on physical judging and their average daily gain (ADG) into two groups (fast growing (FG) and slow growing (SG) sheep) having ADG, respectively above 150 g/head/day) and less than 65 g/head/day. There were very significant differences (P<0,01) on carcass weight, meat yield, bone percentage and weight of pelvic fat and kidney between sheep groups. While for carcass percentage, meat and fat percentage, fat and bone weight, fat thickness, loin eye area, pH value, water holding capacity, tenderness and cooking loss, there were no significant difference between FG and SG lambs. It is concluded that this selection on fast growing sheep can be recommended as increase in ADG did increase expected trait, meat yield, but not carcase percentage and quality. Implementation of this selection continuosly can increase growth performance of local sheep as well as sustainability of good quality of lambs for fattening bussiness. | en |
