Productivity of laying hens of the cross Czech Dominant when using the biologically active additive Api-Spira

Abstract

Currently, one of the factors of increasing the productivity of poultry is the introduction of biologically active additives into the feeding diet, which in turn have a diverse composition and their main role is not only to increase production, but also to improve the quality of producing products at low production costs. One of the well-proven is the biologically active additive Api-Spira. It has been studied with a positive effect on broilers, as well as on some farm animals. It contains only natural substances. The purpose of the research was to study the productivity of laying hens of the cross Czech Dominant when using the biologically active additive Api-Spira. The economic effi ciency of using the biologically active additive Api-Spira at a dose of 1,28 g per laying hen (the 2nd experimental group) was higher than in the 1st control group, where the additive was not used. Thus, the level of profi tability of egg production in the 2nd experimental group was 21,5 %, and in the 3rd and 4th experimental groups it was 16,8 %, which exceeded the indicator of the 1st control group by 5,7 and 1,0 abs.%, respectively. Thus, the study of the productivity of laying hens of the cross Czech Dominant when drinking the biologically active additive Api-Spira showed the eff ectiveness of its use. In order to improve the productivity of laying hens of egg crosses, we recommend the use of the biologically active additive Api-Spira with the main diet of 1,28 g per laying hen for 180 days according to the scheme: a month of drinking, a month break.
