The use of laminaria and lichens in the diet of young cattle. I.Yu. KUZMINA (Magadan Research Agricultural Institute, Magadan).
For the first time, in the conditions of the Magadan Region, studies were carried out to study the effect of introducing a new unconventional feed additive of plant origin into the diets of young beef cattle, consisting of laminaria flour (Laminaria) and lichens – reindeer moss (Cladonia alpestris) and Iceland moss (Cetraria islandica). The feed additive contains a wide range of biologically active substances, natural antioxidants necessary for the life of farm animals and capable of exerting a charitable effect on metabolic processes, stimulating growth and development, possessing antimicrobial and anti-inflammatory properties.
The inclusion of a component feed additive in the diets of calves of the dairy period contributes to an increase in the absolute gain by 5.6 kg (relative gain by 7.16 %) (P ≤ 0.05) relative to the calves of the control group. The relative growth rate according to S. Brody is higher in the experimental young by 3.19 % control.
