In the article we have studied the influence of breeding Stavropol Rams breed and Australian meat merino for increase a wool productivity at offspring received from crossing with Soviet merino females
The article comprises the results of two research-and-production experiments with meat poultry and pigs grown on local forages including biologically active preparations. The purpose of the research was to study the effect of enzyme preparations Cellolux-F and protosubtilin G3x and probiotic feed additive “Sporotermin” on the intensity of growth, development and metabolic processes, and conversion of rations nutrients into production. The results of the research showed that to improve the physiological and biochemical status and intensity of metabolic processes in the body, and also improving the conversion of feed nutrients into products in composition of chickens and pigs’ mixed feed one should feed the mixture of enzyme preparations Cellolux-F and protosubtilin G3x with probiotic feed additive “Sporotermin”

Most modern chemicals designed to protect crop also actually cause negative effects on the protected plants mostly due to side effects and/or not following the application procedures correctly. It is possible to neutralize the negative effects of herbicides they have on cultivated plants with precise use of immunostimulants which will increase the plants' natural immunity against the negative effects of biotic and abiotic environmental factors
