Chickpeas in combination with feed additives in the diets of the replacement chickens and hens of the parental herd of the egg productivity

The purpose of the research was to analyze the use of chickpeas in combination with feed additives Di–lactocin-Ya and Baksin-KD in the diets of replacement young chickens and hens of the parent herd of egg productivity. Initially, a reconnaissance experiment was carried out to identify the optimal dosage of introducing a new feed additive Di-lactocin-Ya into the diets of the replacement chickens of the cross Hisex Brown. In order to do this from the livestock of chickens aged 15–17 weeks four groups were formed. The chickens of the experimental groups in addition to the main diet were fed with a new studing additive Di-lactocin-Ya in doses of 4, 5 and 6 g per 1 kg of feed. According to the results of the experiment, the optimal dosage of the feed additive Di-lactocin-Ya was established for the introduction of 5 g/kg of feed into the diets of breeding young and adult chickens. The main production experiment was carried out in two stages. The fi rst stage of the experiment was carried out on the replacement young chickens at the age of 14–17 weeks during puberty three groups of were formed for this purpose per 70 heads in each. The second stage of the experiment was carried out on adult breeding hens from the moment of transfer to an adult breeding herd to the passage of the fi rst phase of egg production in the period of 18–40 weeks. For this purpose, three groups were formed per 60 laying hens in each. The conditions of feeding and housing of experimental animals were typical, according to the requirements of the technology. The results obtained in the research give grounds to recommend the use in the industrial poultry egg breeding of diets based on local non-traditional ingredients, including chickpeas with the replacement of expensive soybean meal and the replacement of feed antibiotics with feed additives Di-lactocin-Ya and Baksin-KD.
