Summary. The purpose of the research on young growth of cattle was comparative study of the influence of the normalized trace elements in mineral and organic form, and the young growth of pigs in the organic form together with sapropel on growth, development, hematological and biochemical parameters. The article presents the results of two scientific-practical experiments conducted in 2010-2011 in the conditions of the Amur region: the first on young growth of large horned livestock of black-motley breed, the second – the young growth of pigs cross-breeds of large white and duroc. In scientific experiments conducted a test of three feed additives manufactured according to the recipes developed taking into account zonal climatic conditions, the actual density of the feed and the use of soy protein. As a result of performed experiments, data were obtained, which suggests that feeding the fodder additives of young growth of large horned livestock contributed to the increase compared with the control of absolute and average growth of 6.7% in the first trial and 14.9% for the second experimental group. With feeding of the chelate compounds of microelements (recipe №2) piglets first experimental group allowed to increase the average growth of 12.2%, and feeding these microelements together with sapropel (recipe № 3) in the second test group to 18.5%. Feed additives positively influenced the digestibility of nutrients in young cattle for protein, fat, fiber and BEV on 3,6%, 1,6%, 4,9%, 4,8%, and piglets protein is 3.0-4.2%, fat – 10.6 12.9%, and BEV – by 7.6%, respectively. The content of the studied microelements in the blood of pigs’ experimental groups оптимизировалось to a maximum of physiological norm. At the same time, the young animals from the control group their content was slightly below the physiological norm.
Keywords: chelate compounds of trace elements, sapropel, piglets, growth, digestibility of forages.
