INFLUENCE OF FEED ADDITIVE MONOCALCIUM PHOSPHATE FOR JERSEY COWS WITH SIGNS OF OSTEODISTROPHY

Abstract

One of the common disorders in highly productive animals is nutritional osteodystrophy, which leads to significant economic losses. Most often, a violation of mineral metabolism is observed in highly productive cows during lactation, when their last caudal vertebrae soften or completely disappear. To achieve the best physiological parameters of Jersey dairy cows, we were tasked with studying the practical significance of using the Monocalcium Phosphate feed additive in the treatment of nutritional osteodystrophy in Jersey cows in industrial livestock farming conditions. The purpose of the research work was to establish the effect of the feed additive “Monocalcium phosphate” in the treatment of nutritional osteodystrophy in cattle. We formed two groups of animals, according to the principle of analogous pairs in age and live weight (n=75). The control group was fed according to the diet generally accepted on the farm. In the experimental group, “Monocalcium phosphate” was administered with animal feed for 30 days at a rate of 100 g/animal. daily. During the first five days, the dose was gradually increased. On the first day, the additive was introduced at the rate of 10 g/ bird, on the second day – 20 g/bird, on the third – 40 g/bird, on the fourth – 60 g/bird, and then 80 g/bird. once. The duration of observations was 30 days. Blood for analysis was taken from the saphenous vein in the neck in the morning, before feeding the animals. The results of the experiment showed that the inclusion of monocalcium phosphate in the diet of animals had a positive effect on the clinical composition of the blood. In particular, in the experimental group the level of hemoglobin increased by 3.2%, total protein - by 6.2%, reserve alkalinity - by 10.1%, Ca - by 2.56% and P - by 17.07% at optimizing the ratio of microelements. Thus, based on the research conducted, it has been established that that the use of “Monocalcium phosphate” in the diets of dairy herds helps to improve metabolic processes in the body of animals, normalize mineral metabolism, and, consequently, prevent nutritional osteodystrophy.
