Оценка эффективности фитодобавки из астрагала нутового в составе концентратной части рациона сельскохозяйственной птицы

Abstract

The article presents the main results of feeding phytoadditive of Astragalus chickpea to egglaying poultry in order to improve metabolic processes and increase productivity. The research was carried out in 2022 at the Perm Research Institute of Agriculture, Perm Federal Research Center, Ural Branch of the Russian Academy of Sciences. The fundamental task of agriculture in Russia is to increase the volumes of livestock production. The use of supplements consisting of local plant resources, such as Astragalus chickpea feed supplement, which has a high content of various biologically active substances, may be a good option for providing the necessary nutrients to poultry.The tested feed phytoadditive has a positive effect on indicators such as egg production, egg laying intensity, egg weight, amount of carotenoids and egg shell thickness. The study is aimed at the possibility of including a feed additive in the composition of poultry feed under conditions of intensified production. When introducing a phytonutrient feed additive into the main diet of laying hens, the following results were obtained: the ratio of protein mass to yolk mass in the second experimental group indicates an increase in the proportion of yolk in the egg composition by 1.25% compared to the control group, a higher content of carotene in the feed mixture, which affected its content in eggs (by 1.9% and 7.0%, respectively, compared to the control group). An increase in shell weight was noted due to an increase in its thickness by 0,34% in eggs from chickens of the second experimental group compared to the control group.
