Efficiency of using premixes based on the "Gorlinka" concentrate in the feeding of laying hens |
|
|
This article presents the results of studying the effectiveness of using a new premix based on processed products, in particular oil cakes. The research was carried out in the conditions of the second-order reproductive productor of the public organization "Svetly" of the Svetoloyarsk region of the Volgograd region in the period from 2015 to 2017. In the course of the scientific and economic experience, the positive effect of the developed premix on the egg productivity of the laying hens of the parent herd, on the morphological and incubation parameters of the eggs, and on the young ones was revealed. The use of a premix on the basis of a mustard protein-containing feed concentrate "Gorlinka" contributed to an increase in the laying capacity of laying hens, as a whole the group received 324 pieces more than in the control. The average weight of the egg from the hens of the control group was 61.97 g, the experimental -62.75 g, which was higher than in the control by 0.78 g. When analyzing the morphological parameters of the incubation eggs, it was found that all parameters are in the permissible limits of physiological norm. The fertilization of eggs in the control group was at the level of 90.33%, which is lower than in the experimental group. As a whole, eggs were taken out by groups in the control group 19.00%, in the experimental group - 14.33%.
