Effectiveness of the use of probiotics in the diet of broiler chickens

Abstract

<b>The aim of the experiment was to research the productivity, slaughter qualities and broiler chicken meat quality using a probiotic feed supplement. The research objectives were solved experimentally using zootechnical and statistical research methods. It was found that the probiotics application in the feeding of broiler chickens increased live weight by 11.9%, the average daily gain was higher by 12.1%, absolute by 12.2% and reduced feed consumption per 1 kg increase by 8.9% compared with control. Additional consumption of probiotic feed supplement by broiler chickens increases the pre-slaughter live weight by 12.0%, the weight of ungutted carcass by 12.1%, semi-gutted carcass by 9.9% and gutted carcass by 13.3% relative to control. Consumption of probiotics by broilers increased the level of total moisture by 1.3% in the pectoral muscles, and hygro-moisture was higher by 0.2% in the thigh muscles; the amount of nitrogen was higher by 0.2% compared to the control group.

Influence of Phytobiotic and Synbiotic-Acidifier Blend Supplements on Hemato-Biochemical Indices, Antioxidant Enzymes and Gut Microflora of Broiler Chicken

“…In addition, they can be utilized to modify the gut microflora by reducing the number of pathogenic organisms and decreasing the microbial burden on the animal's immune status (Abdelli et al, 2021). Probiotics are feed supplements that contain live strains of selected beneficial microorganisms or growth stimulants of microbial, animal, plant origin that help to improve the health of the host (Markowiak and Śliżewska, 2018;Poberezhets and Kupchuk, 2021). They are useful in improving the microbiological balance of the intestines and strengthening the intestinal barrier against the influence of harmful factors (Vineetha et al, 2017(Vineetha et al, , Żbikowski, et al, 2020.…”
