Effect of fodder ingredient on meat productivity and development of internal organs of broilers

Abstract

Abstract Annually, there is an increase in the cost of soybean components of feedstuffs, which negatively affects the profitability of poultry farming. The use of cheaper alternative feeds in poultry diets such as rapeseed flour, as well as sunflower kernels and seeds, brings novelty to fodder production and broiler feeding. The purpose of these studies was to determine the impact of unconventional fodder ingredients on meat productivity and the development of internal organs of broilers. The results of the experiment on the use of rapeseed flour in the diets of turkeys show that its introduction into the diets reduces their pre-slaughter living weight and the weight of the ripped carcass. Development of the internal organs of the experimental groups was comparable to those of the control group. The inclusion of sunflower kernel and seeds in the diet contributed to increased meat productivity and better development of internal organs in broiler chickens. Compared to the sunflower core, broilers receiving sunflower seeds and the enzyme preparation Ronozim tended to increase the weight of internal organs, while the greatest differences were established by the relative weight of the gizzard (when using 5% of fodder ingredients - by 0.05%, and when using 7.5% - by 0.03%).
