Feeding technology for producing high-grade beef
In the past, South Korea had the best economic benefit of slaughtering yak of 450 kilograms in 18 months of age when it was fattening beef cattle (high daily weight gain and feed remuneration), but only 40% of the total carcass meat could meet the high-grade annual meat requirements. about. Now, a set of programs to obtain high-grade beef products from changing feeding techniques has been concluded: During the growth period, the feed should be high protein, low energy, mineral and vitamin balance. Concentrates are limited to 1.2% to 1.5% of body weight, roughage feed intake, daily gain of 0.7 kg to 0.8 kg. In the early period of fattening (from 13 months to 18 months), the fine material is controlled at 1.7% to 1.8% and the roughage is free to feed. All feeds at the end of the fattening period are free to feed. To maximize the use of roughage and concentrate feed, the crude protein content during the growth period was 14% to 19%, and the total digestive nutrients were 68% to 70%, ie, high protein and low energy; during the fattening period, it was the opposite, ie high energy and low protein. Meet the deposition of intermuscular fat and form a layered pattern of marble; Extend the rearing period of the fattening, slaughtered from an 18-month-old 450 kg, extended to about 5,000 kg in 24 months of age. According to this program, leg muscles and marble layer white muscle can reach 75% to 82% of the total, the percentage of high-grade beef can be increased by 35% to 42%, and the total economic benefit can be increased by 24% to 27%.
