Dynamics of changes in the productive quality of hens under the influence of selenium and phyto additives

Abstract

Analysis of the survey shows that when included in the diet of laying hens first experimental group sodium selenite mass index eggs end of the study increased by 1,9 % compared with the control group. In laying hens second experimental group who were given phyto additives also observed an increase in egg weight compared with the control group to 2,27 %. A similar situation was observed in laying hens third experimental group were fed sodium selenite combined with phyto additives, egg weight increased by 2,49 % (p <0,001) compared to the control group. It should be noted that an increase in weight of the eggs increases the mass of its parts. Since the average weight of yolk egg laying hens first experimental group were fed sodium selenite increased by 2,8 %. In laying hens second experimental group who were given phyto additives also observed an increase in the average weight of the yolk by 7,4 % (p <0,001). In the third experimental group, which was administered in the diet sodium selenite combined with phyto additives average yolk mass increased by 7,0 % compared to the control group. Quality eggs directly depend on egg weight and the thickness of the shell and its mass.As seen from the results eggshell mass index increased at the end of the experiment, laying hens first experimental group by 7,8 % (p <0,05) compared with control. In laying hens second experimental group who were given phyto additives also observed increase in egg shell weight by 5,4 % at the end of the experiment. A similar trend of increasing egg shell weight by 6,2 % was observed in laying hens third experimental group were fed sodium selenite in combination with medicines.In laying hens as the second experimental group who were given phyto additives with basic diet and the third experimental group were fed sodium selenite combined with phyto additives indicator index form eggs in both groups was higher by 1.0% compared with the control and amounted to 76,97 g (p <0,05) and (p <0,01), respectively. In laying hens the first experimental group in which diet was administered sodium selenite significant differences from the control group did not. Analyzing the effects on egg production of laying hens sodium selenite combined with feed phyto additives “Fitopank” and “Fitohol” we can conclude that during the experiment observed increase productivity in all experimental groups of hens compared to the control. Thus, in the first experimental group egg production increased by 9,5 %, second group – 9,3 %, in the third – 9,9 % compared with the control group. In addition, the use of feed enriched with sodium selenite and phyto additives "Fitopank" and "Fitohol" possible not only to minimize the number of non-standard carcasses, but also struck out the possibility of their occurrence, which is confirmed by the absence of unusual carcasses in the third experimental group.As the results of our study, weight carcasses likely increases in laying hens first experimental group was 17,9 %, the second research – by 18,5 % and the third 20,4 % (p <0,01), respectively. Thus, we can assume that the enrichment of the diet of hens-layers with sodium selenite and phyto additives “Fitopank” and “Fitohol”, which includes a significant amount of biologically active substances that contribute to the complex action on the body of chickens and, accordingly, positively affect the product category, slaughter output, increase pre-slaughter weight and, as a consequence, an increase in the mass of non-disembowel and disembowel of carcasses.
