Ecological and Biochemical Evaluation of the Kalmyk Cattle Meat When Including Mineral Feed Additives in Fattering Bulls Diet

Abstract

The article presents the study results of the Kalmyk breed bulls meat chemical composition, that had been fed local non-traditional feed additives — zeolite and salt. The data shows differences in chemical composition of the average sample bulls meat, in the experimental group dry matter was from 27.09 to 31.02%, meat protein was 2.97% higher, and fat was 2.18% higher than the control group. The ratio of protein and fat in both group meat was 0.62-0.64. In studied meat samples was different vitamin content. In the experimental animals meat, B1 vitamin was 26.8% higher, B2 -5.9%, E - 2.6%, PP - 8.2%. Studies show that the mineral additives in the diet contributes to a greater accumulation of dry matter, nutrients, and vitamins. Under such technology, beef has a great energy density and biological value. The article also reflects the study results of the Kalmyk bulls meat macro- and microelement composition. When analyzing the data, we found that the animals receiving natural feed additives have the best ultimate composition in their meat.
