Abstract
When feeding 30-180-day old calves with mineral sorbent vodnite, the number of red blood cells increases by 4.17% (p≤0.05), the hemoglobin level increases by 9.4% (p≤0.05), total protein content by 6.44% (p≤0.01), albumin content by 4.60% (p≤0.001), the phagocytic activity of leukocytes by 12.42% (p≤0.05), the bactericidal activity by 6.47% (p≤0.05), the lysozyme activity by 10% (p≤0.05), the average daily weight gain of calves by 7.4%, the live weight by 7.6% (p≤0.01). In fresh cows fed with vodnite, physical and biochemical characteristic improve and the gross milk yield increases by 45–84 kg (p<0.05). Vodnite used for cattle increases the genetic productivity.
Highlights
In the conditions of increasing technogenic and anthropogenic pressure on the environment, the problem of environmentally friendly additives, immunocorrectors and natural minerals in livestock breeding is relevant
Scientific research was carried out in the conditions of ZAO “Lunacharsk” of Stavropol district of Samara region and the research laboratory of the faculty of biotechnology and veterinary medicine of Samara State Agrarian University. 60 fresh cows were used in compliance with the principle of analogues
The live weight decreased since the 10th (491.3 ± 3.8 kg) to the 240th day of lactation (486.2 ± 3.9 kg)
Summary
In the conditions of increasing technogenic and anthropogenic pressure on the environment, the problem of environmentally friendly additives, immunocorrectors and natural minerals in livestock breeding is relevant. Zeolites can be used as well since they have a unique combination of ion exchange, catalytic, adsorption, detoxification, deodorizing, prolonging effects on the animal body [1,2,3,4]. Their use increases the absorption of nutrients, makes it possible to reduce feed consumption [6,7,8,9]. It is advisable to use zeolites, bentonites, flasks, dolomites, tripoli and other aluminosilicate rocks to eliminate the mineral deficiency in local feed resources, which can prevent secondary immunodeficiency states, macro- and microelementoses, and stimulate natural resistance and productivity of farm animals [10]
