Effects of chelate forms of bioelements on bovine productivity

Abstract

The effectiveness of the use of Biocink on the productivity of cattle has been shown. The body weight gain of the test calves of the black and motley breed of four months of age after 30 days of the experiment exceeded the growth of the calves of the control group by 64,28%. Body weight was 148,52±5,40 kg (29,13% increase). Hematological analysis showed that the number of red blood cells in both groups was within the physiological norm. At the same time, the number of erythrocytes in the control group after 30 days increased by 31.5%, in the experimental group - by 40.5%. The hemoglobin content in the red blood cell in the calves of the control group was 79.8 ± 1.25 g/L (an increase of 10.4%), in the experimental group - 112.7 ± 3.18 g/L (an increase of 32.3%). The hematocrit value at day 30 of the experiment in the control group was 25.46 ± 0.57%, in the experimental group - 35.25 ± 1.47%. The average red blood counts were at the minimum limits of normal. As a result of organoleptic studies of milk, it was noted that the appearance of the product is characterized by an opaque liquid, which complies with regulatory requirements. The consistency is liquid, homogeneous, without protein flakes and stray lumps of fat. Taste and smell characteristic of milk, without extraneous tastes and smells. The color is white, uniform throughout the mass. A positive trend was observed after the use of Biocink, which resulted in a significant improvement in the indicators confirming the quality and safety of milk and dairy products. The use of Biocink in the diet of experimental groups of animals led to the optimization of metabolic processes, which can be explained by the composition of Biocink, which contains complexes of essential amino acids and organic trace elements.
