Показатели обмена веществ племенного импортного скота при адаптации в условиях Алтайского края

The main causes of metabolic disorders include the nonconformance of the cattle management and nutrition practices to the level of its inherent genetic performance. Those causes should be controlled during the adaptation of imported breeding cattle. The research goal was to study the adaptation mechanisms (clinical, biochemical, morphological and immunological status) of imported breeding cattle under the conditions of animal farms of the Altai Region. The studies involved Simmental heifers imported from Austria at the age of 19-20 months, pregnant for 5-6 months. It was found that the main indices of the clinical status and morphological blood indices throughout the study corresponded to the physiological range. The immunological status of the animals was also within the physiological range except for the first examination. Most blood biochemical indices of the imported cattle were below the minimum physiological values after the transportation. Later on, increasing metabolic dynamics both in imported and local cattle was revealed, but the increase in the imported animals was more intensive compared to that of the local animals. The comparative analysis of the biochemical indices of imported and local breeding cattle showed that despite the lower initial values of the basic biochemical indices in the imported cattle their increasing dynamics towards the maximum physiological values was indicative of a high genetic potential of the animals and their high adaptation ability.
