Physiological status of the BLV-infected cows offspring under dyspeptic manifestations correction

Abstract

The BLV-infected cows’ offspring are at risk due to a decrease in their viability and productivity indicators. The purpose of the studies is a comparative analysis of hematological parameters and indicators of body weight gain in obtained from immunocompromised cows calves when correcting their clinical status using the composition we have developed (patent No 2646831) and a broadspectrum antibiotic. According to our data, calves from BLV-infected mothers were born with a body weight of 6-7% less than calves from intact cows. With the correction of dyspeptic manifestations in calves by the proposed method, the average daily gain in animals remained at the level with intact ones (630-660 g / day), and when using an antibiotic, it was 300-500 g per day. Hematological studies have shown that with clinical manifestations of dyspepsia in neonatal calves, hypovolemia and pronounced leukocytosis are noted in the blood, the signs of which decrease by the 12th day of life during therapy. The glucose of blood serum in calves with dyspeptic syndrome was slightly reduced on the first day. There was a change in the blood electrolytes ratio, a decrease in total blood protein and albumin content, compared to intact animals. Thus, our studies have shown that when correcting dyspepsia in neonatal calves from immunocompromised cows using the composition we have developed, the body weight gain retained, which was due to the rapid normalization of the homeostasis in animals.
