Abstract
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%.
