DEVELOPMENT OF LITHIUM–CONTAINING FEED ADDITIVE AND ITS USE FOR FORTIFICATION OF CHICKEN BROILERS MEAT AND BY-PRODUCTS
The article presents the researches on the development of a feed additive for broiler chickens, including succinic (amber) acid, zinc sulfate, manganese sulfate, copper sulfate, lithium carbonate, L-carnitine, betaine. It was found that the introduction of the developed feed additive to mice food in a dose exceeding 5000 mg / kg per body weight did not affect the general condition of the animals. The experimental results did not allow determining the LD50 of the researched feed additive. The lithiumcontaining feed additive does not have chronic toxicity, does not cause pathological processes in the internal organs of mice and it belongs to hazard class IV (low-hazard substances). It was found that the introduction of a feed additive in amount of 2,350 g per 1 ton of mixed forage for broiler chickens (the concentration of ionized lithium is 66 mg per 1 kg of feed) allows increasing the content of lithium in cooked meat, minced meat and by-products in comparison with samples of products taken from the experimental group. The lithium content in boiled white meat is 0.418 mg / 100 g, which is 211% higher than in the control sample; 0.452 mg / 100 g in boiled red meat which is 426.4% higher than in the control sample. Eating of 300 g of boiled chicken meat fortified with lithium obtained in the process of broiler chickens cramming, this meat provides the recommended daily dose of the specified trace element. The obtained data allow using the raw meat and by-product for the production of lithium fortified food products.
