The invention relates to a fine and rough feed composition for a latter fattening period of high-quality
beef cattle and a feeding method of the fine and rough feed composition. A fine feed is prepared by taking corns and corn germ cakes as main materials, and adding brans,
cottonseed cakes, soybean cakes,
calcium hydrogen phosphate, table salt, baking soda, microelements,
vitamin AD3
powder and the like. A rough feed is prepared from 50% of ensiling corn straws and 50% of fresh brewer's grain. The feed resources including the ensiling corn straws, the fresh brewer's grain, the
cottonseed cakes and the like are sufficiently utilized so that the cost of the feed is greatly reduced and a feeding method of
free feeding of the fine feed for the latter fattening period of the high-quality beef, quantity-limiting and fixed-time feeding, and first-rough feed and second-fine feed feeding is realized;
nutrition needed by
muscle growth of the
beef cattle and deposition of fat between
muscle fibers is sufficiently met; the synchronization of the
muscle growth and the rapid deposition of the fat between the muscle fibers is realized; the beef color and the fat color and luster meet the standard requirements. The dependence on barley and straws by the latter fattening period of the high-quality
beef cattle is completely removed; the beef performance indexes including daily
gain of the beef cattle, the slaughter performance, the high-quality beef block yield and the like are improved.
