Application of iodine helated forms, cobalt and selenium when feeding young cattle

The article explores hematological and biochemical parameters of blood, dynamics of live weight gain of young cattle of black-and-white breed when being fed feeding of a fodder additive. The experiment was conducted under conditions of dairy complex Priamurye of Tambov district of Amur region in 2017-2018. The researchers arranged experimental groups of calves by means of similar pairs taking into account age, live weight and physiological condition. There were three groups of animals arranged, one control group and two experimental ones. Each group included 10 calves aged 12 months. The conditions of young cattle keeping were similar. The control group calves were fed with basic diet at the farm, the 1st experimental group received iodine, cobalt and selenium in mineral form, whereas the 2nd experimental group received the same elements in helated (organic) form. At the end of the experiment, the coefficients of digestibility of crude protein, crude fat, nitrogen-free extractives and crude fiber were determined on the basis of the data on the amount of nutrients consumed and isolated by animals with feces. When microelements in mineral and helated forms were included in the basic diet of young cattle, microelements in organic form had a positive effect on hematological and biochemical parameters of blood of calves of the 2nd experimental group. Application of elements in organic form in the diets of young cattle increased digestibility coefficients of nutrients. This contributed to live weight gain, average daily and absolute growth of animals in the 2nd experimental group.
