The effect of young ram’s genotype on mineral metabolism

The article presents the results of studying the features of mineral metabolism in the body of purebred Romanov sheep (group I), its crossbreeds of the first generation with Edilbai – ½ Romanov × ½ Edilbai (group II) and the second generation – ¼ Romanov × ¾ Edilbai (group III). It was found that due to the effect of crossing, crossbred sheep of groups II and III outperformed purebred peers of group I in terms of calcium and phosphorus intake with feed by 3.93‑20.39% and 12.23‑14.63%, their deposition in the body – by 15.30‑25.07% and 16.20‑17.88%, the value of the utilization factor from the accepted – by 0.38‑1.92% and 1.56‑4.57%.
