Вплив диференційованого за живою масою утримання та годівлі батьківського стада індичок кросу «Харківський» на їхні відтворні властивості

Abstract

The purpose. To study the influence of technological method — differentiated by live weight growing and feeding of the parent herd of turkeys of cross «Kharkivskyi» on their reproductive properties. Methods. Zootechnical, zoohygienic and statistical. At the age of 30 weeks, all the turkeys were transferred to the parent herd, where they continued to be kept and fed in groups. The nutritional characteristics of the feed, which was fed to turkeys of all groups, were similar and met the requirements. During the studies, egg production, poultry safety, feed consumption were determined according to daily data. Egg incubation parameters were determined by visual inspection, weighing and scattering of all obtained eggs and the results of their incubation. Results. The positive effect of the proposed technological technique on egg production, the yield of hatching eggs and total yield of turkeys per initial turkey was established. The data obtained indicate the advantage of the experimental groups of turkeys compared with the control according to the above indicators, respectively: for the 5th line — by 6.5%, 2.2% and 5 goals.; for the 6th line — by 3.2%, 0.7% and 1.2 goals. In the experimental groups, the lower feed consumption per 10 pieces of obtained eggs was also observed (at growing turkeys of the 5th line — by 9.7%, 6th — by 7.3%). Conclusions. Differentiated by live weight growing and feeding of the parent herd of turkeys of cross «Kharkivskyi» helps to increase their reproductive performance.
