Abstract
The results of research on the products of slaughter of Simmental bulls for various selenium-containing additives in the diet are presented. Determination of the morphological composition of carcasses has shown the advantages of experimental groups of animals over the control in the higher content of flesh in the carcass (6.1-8.2 kg) and a slightly higher ratio of meatness (0.05-0.08). In the carcasses of experimental bulls, bone content decreased (18.7-18.9% versus 20.1% in control). The best results of meat productivity were obtained in the group of animals fed with the preparation Devivit in the diet. In the samples of meat of bulls of experimental groups there was definitely, although biometrically insignificantly (P> 0.05) by 0.28-0.55% less water (76.41-76.14 against 76.69%), and by the same amount more dry matter. The introduction of selenium supplements in the diet of bulls of the 1st and 2nd experimental groups resulted in an increase (compared with the control) in muscle protein content by 2.9 and 4.4 absolute percent (P> 0.05), while the concentration of fat in this case, on the contrary, fell by 14 and 17.1%, respectively (P> 0.05). The level of tryptophan in the animal meat of experimental groups was higher than in the control by 2.29-4.4 mg%, and that of oxyproline, which reflects the worst grades of meat, on the contrary, was by 1.31-4.25 mg% lower. As a result, the protein-quality index (the ratio of tryptophan to oxyproline) in experimental samples of meat was different from the control by 0.2-0.5. Meat quality evaluation on a 3-point scale by tasting the broth showed no significant difference between the groups. However, the tasting score of boiled meat of bulls of experimental groups, which was conducted on a 5-point scale, averaged 4.35, and 4.17 points (in the control), which is 4.1% less than in the samples of meat of experimental animals. In the fattened young, selenium content in the oblong muscle of the back varied within 0042 (control) -0087 mg / kg , which is completely acceptable and safe. From this it can be concluded that beef can be one of the sources of replenishment of the lack of selenium in the human diet
