Abstract

This study was conducted to estimate maintenance requirements and net growth requirements of calcium (Ca), phosphorus (P), potassium (K), sodium (Na) and magnesium (Mg) for Dorset×Thin-Tailed Han crossbred male lambs during 35 to 50 kg of body weight. Twenty-five 6-month-old Dorset×Thin-Tailed Han crossbred male lambs weighted (34.54±0.40) kg were randomly divided into 5 groups, which were baseline group, intermediate group, and last group 100%, last group 60% and last group 40% (feeding levels were 100%, 60% and 40%, respectively). baseline, intermediate and last groups were slaughtered at 35, 43 and 50 kg, respectively, to determine the contents of Ca, P, K, Na and Mg in animal tissues, and to establish the mathematical models for predicting maintenance requirements and net growth requirements. The results showed that during 35 to 50 kg of body weight, maintenance requirements for Dorset×Thin-Tailed Han crossbred male lambs were 0.73, 0.72, 0.32, 0.32 and 0.13 g/d, respectively, and net growth requirements were 13.47 to 14.00 g/kg EBW, 7.18 to 7.41 g/kg EBW, 0.13 to 0.17 g/kg EBW, 1.20 to 1.73 g/kg EBW and 0.45 to 0.58 g/kg EBW, respectively. The study proposes models of mineral requirements for Dorset×Thin-Tailed Han crossbred male lambs during 35 to 50 kg of body weight.
