title: Effects of suckling duration on growth, slaughtering and carcass quality characteristics of Kivircik lambs.
abstract: Effects of suckling length (45, 75 and 120 days) and birth type (single and twin) on lamb growth, slaughtering and carcass quality characteristics were investigated using 40 Kivircik lambs. SC-45 and SC-75 lambs were weaned at 45 and 75 days of age, respectively, whilst SC-120 lambs remained with their mothers until the end of the experimental period. Lambs from all studied groups were slaughtered at 120 days of age. Weaning treatment caused a decrease in average daily gain in SC-45 and SC-75 lambs, and therefore, final weight was higher in SC-120 lambs than lambs from weaned groups. SC-120 lambs had higher empty body weight, cold carcass weight, dressing percentage, carcass measurements, carcass fatness (proportions of the kidney knob and channel fat, subcutaneous and intramuscular fat in pelvic limb) and non-carcass fatness (omental and mesenteric fat proportion) than weaned lambs. As a conclusion, the potential losses in meat production due to weaning should be considered before deciding the weaning of lambs at early ages.
