in principle
Shelf large, fast weight gain, lean meat, less fat, no disease.
Selection request
The breed type can be selected from the hybrids of purebred bull sperm of Simmental, Angus, Piedmont and local cattle, known as hybrid cattle. The general growth speed and feed utilization ratio of these cattle are high, and the feeding period is short. It is quick and profitable.
The age requirement is to select shelf cattle over 2 years old and weighing over 300 kg. Gender requirements
Generally bulls should be selected as beef cattle, followed by calves, and the second is cows, because the bulls gain the fastest weight, and the feed conversion rate and lean meat ratio are high. Such as the production of high-grade beef, should be selected over 2 years of age bull, first castration, otherwise its crude fiber rough, and the meat smell, reducing food value.
Physical appearance requirements
The ideal appearance requirements for fattening cattle are: the head is more fleshy, the neck is short and thick, the chest is wide and deep, the ribs are open and fleshy, the back and hips are wide, the limbs are short and straight, the skin is soft, the hair is bright, the muscles of the body are full, the whole cow On the side of the body, it looks like a "brick" shape, and it looks like a "bucket shape". It should be noted that the young calves with large heads, large bellies, thin necks, and pointed tips (which are mostly undeveloped in their early development) and big calves that resemble calves (having slender limbs, small abdomens, and shallow bodies) have restricted their fertility in youth. , should not be beef cattle. This type of cattle fattening takes a long time and costs a lot, so it is difficult to increase the amount of meat produced by fattening.
Health requirements
When choosing, you should learn from the original breeder about the origin of the cattle, the history of use of the animals, the growth and development of the animals, etc., and walk through the cows to observe whether the eyes look good, whether the nose is wet, and whether the feces are normal, etc., so as to make a preliminary judgment on the health of the cows. If necessary, the veterinarian should be consulted to diagnose. The severely ill cow should not be selected. The diseased cows should be cured after being cured. Lying requirements
In general, the shelf life of cows is different due to different nutritional status. It can be judged by naked eye observation and actual touch. It should mainly pay attention to the fullness of the ribs, spine, cross, lumbar and hip muscles. If the bones are obviously exposed, the sensation is middle and lower; if the bones are not obvious, but the hand feels It is obviously medium; if the hand feels less obvious, it means that the muscle is fuller, and it is middle and upper grade. When buying, the price of cattle and the length of fattening can be determined accordingly.
