Beef for baby food from bulls and castrates

Abstract

The research was conducted to compare bulls and castrates in relation to the morphological composition of carcasses, the yield of beef suitable for the production of baby food products, and the quality and safety of raw meat. The research was based on the results of monitoring the safety of the environment, feed, and meat raw materials during the growing and fattening of steers with a meat productivity direction. The pre-slaughter weight and the yield of lean beef of 16-month-old Hereford bull-calves are higher in comparison with castrated animals of the same age, by 6.4 and 1 %, respectively. The muscle tissue of castrates contained 11.5 % of fat, and bulls 9.7 %. The protein content in the longest muscle of bulls was 19.8 %, and in castrates-17.0. The amount of fat beef that is not suitable for baby food is higher in castrate carcasses by 4.7 % compared to bull calves. A high protein quality index of the longest muscle of bulls (6.5) indicates a higher biological value of beef compared to meat from castrates (4.1). In terms of the content of residual amounts of pesticides, toxic elements, and antibiotics, the meat of castrates and bulls of the Hereford breed had no significant differences.

Comparative characteristics of meat productivity of holstein and black-and-white breeds

“…According to the data obtained, the meat of steers of the presented groups met the requirements of GOST 31798-2012 . The need to assess the safety of meat raw materials for the presence of pollutants in them is noted by many authors [5]. This is due to the need to provide the population with environmentally safe products, including beef, where the content of toxic substances should not exceed the maximum permissible concentrations (MPC), which is of great social importance [4,5].…”

The analysis of the obtained data confirms that the concentration of heavy metals in the muscle tissue of young animals does not exceed the maximum permissible concentration.…”

“…It is possible to solve it in several ways, one of which is the breeding of beef cattle. Abroad, the problem of increasing beef production is solved through the development of specialized beef cattle breeding, using intensive meat breeds [1,5,11].…”

“…When creating the industry of beef cattle breeding in the Krasnodar Territory, it was supposed to meet the needs of the population in beef. Since in recent years the number of beef cattle remains insufficient, in some farms, bulls of dairy breeds are raised and fattened, while their intensive rearing is being introduced [3,4,5,14].…”
