Effect of adsorbents in diets on production efficiency of broiler with high nutritional and ecological characteristics

Abstract

Metallurgical enterprises are the main source of environmental pollution with heavy metals. Toxicants pose a serious threat to the consumer's health, so scientific research on diminishing their adverse effect on sanitaryhygienic properties of poultry meat is of high importance when organizing effective environmental management and ensuring food security. The purpose of the study is to devise a method for reducing a negative impact of heavy metals on productivity and sanitary-hygienic properties of meat by admixing adsorbents to a formulation of animal feeds. To analyse the concentration of heavy metals, the atomic adsorption method was applied. Experimental data were statistically processed using SNEDECOR application package. In the industrial territory of RNO-Alania, the prudent use of the adsorbents such as citrus pectin in the amount of 200 g/ton and Toxiban Max in the amount of 1000 g/ton admixed to barley-corn-soybean based feeds of local production allows achieving the maximum effect. Due to the synergistic effect of the tested drugs, there was an increase in the number of red blood cells, haemoglobin and bactericidal and lysozyme activities in the blood of the experimental birds; at the same time, the concentration of zinc lowered 1.98 times, lead-2.71 times and cadmium-2.03 times. The broiler chickens of the 4-experimental group were different from the 1-control analogues in weight parameters, slaughter yield and protein qualitative index which increased by 12.9%, 0.74% and 17.8% respectively. Zinc concentration in the examined muscle samples was 3.48 times lower than in the 1-control group, lead concentration-3.11 times and cadmium concentration-3.54 times.

Effect of animal by-products on the growth performance of broiler chickens

“…Today, mostly blood meal is being used as by-pass protein ingredient in ruminant diet (Kamalak et al, 2005;Taylor, 2005). The practice of feeding additives like yeast (Tsugkieva et al 2021) and adsorbents (Temiraev et al 2020) to increase the growth and productivity of broiler chickens has also been reported previously. However, very little information is available of blood meal use in broiler diet.…”

Гематологические Показатели Молодняка Гусей, Потреблявших Витаминную Добавку

“…В опытных группах, при увеличении дозировки кормовой добавки Витаммин у гусят отмечено повышение уровня тканевого дыхания, что характерно при увеличении обменных процессов и как следствие, повышении продуктивности. Полученные результаты согласуются с мнением ученых, экспериментально установившим, что использование различных кормовых добавок, в том числе витаминных, позволяет улучшить продуктивность и физиологические показатели птицы [9,10,11,12,13,14,15,16…”
