The effect of feeding system on fattening performance, slaughter, and carcass characteristics of Norduz male kids.

The study was conducted to determine the effect of feeding systems on fattening performance, slaughter, and carcass characteristics of male Norduz kids. In the study, 20 male Norduz kids weaned at 2.5 months of age were divided into two groups after weaning. The first group was reared under semi-intensive conditions (SI) on a mixture of pasture and concentrate, and the second group was reared under extensive conditions (E) on pasture only. SI group had higher final weight (35.30 kg versus 32.81 kg), daily weight gain (153.10 g versus 132.14 g), and warm carcass yield (44.84% versus 46.55%) compared to the E group although there were no significant differences. Body organs, carcass parts, prime cuts, and chemical composition of the chop area did not also differ in two groups significantly. As a conclusion, this study showed that semi-intensive feeding systems improved kid fattening performance and carcass characteristics.
