METHOD OF INCREASING MEAT PRODUCTIVITY AND ENVIRONMENTAL SAFETY OF BROILER MEAT BY FEEDING ADSORBENT AND ANTIOXIDANT

   In recent years, the use of adsorbent and antioxidant preparations in the formulation of feed with a high content of heavy metals is a promising direction in the industrial production of broiler meat. The study aims to study the consumer and hygienic properties of broiler meat when including adsorbent Ferrotsin and antioxidant Selenopyran in diets with high heavy metals and aflatoxin B 1 content. The authors experimentally established the necessity of containing the adsorbent Ferrotsin in the dose of 300 g/t feed and the antioxidant Selenopyran in the quantity of 300 g/t feed into the composition of mixed fodder with excessive concentration of heavy metals. This inclusion of adsorbents and antioxidants in the compound feed composition is necessary to increase the nutritional properties and protective properties of poultry meat. Group 3 broiler chickens significantly exceeded (P < 0.05) the control counterparts by 18.88 % by weight of half-gutted carcass and 18.26 % by weight of the gutted carcass. Also, broiler chickens of the 3rd experimental group exceeded the content of solids in the thoracic and thigh muscles by 1,40 and 0,60, and protein by 0,67 % and 0,67 %. Group 3 broilers significantly (P < 0.05) exceeded the control in protein quality index (PQI) of meat by 18.86 %. In broilers of experimental group 3, there was a reliable (P < 0.05) decrease in the level of zinc by 3.07, cadmium by 2.25 and lead by 3.24 times in the samples of breast muscle relative to the control counterparts. The highest final score was obtained by boiled white poultry meat of the 3rd experimental group. This sample of meat reliably (P < 0.05) exceeded the total sum of organoleptic parameters of the control sample by 0.81 points. In broilers of experimental group 3 in examples of breast, thigh muscles and meat homogenate, the level of selenium was significantly higher than in control due to the presence of this substance in Selenopyran.
