Certain Carcass Quality Characteristics of Saanen Kids in Natural and Artificial Rearing Systems
Öz
In the study, it was aimed to compare certain carcass quality traits of Saanen kids reared naturally or artificially and slaughtered at 80 or 120 days of age. There was no significant difference between the carcass weight and commercial dressing of the natural and artificial reared kids. On the other hand, real dressing percentage showed higher results in artificially reared kids compared to natural reared kids. The effect of rearing type on the kidney knob and channel fat (KKCF) and subcutaneous fat proportion in hind limb was found insignificant, while the intermuscular fat proportion in hind limb was higher in the natural reared kids. Parallel to the increase in slaughter age; carcass weights, carcass compactness and hind limb compactness indices and proportion of flank and neck increased. The effect of slaughter age on proportions of KKCF, subcutaneous and intermuscular fat in hind limb was not detected significant. Meat ratio in hind limb was found higher on kids that were slaughtered younger. Breeders who aim to get high milk yield can rear Saanen kids artificially, without causing any negative effect on carcass quality traits.
