Abstract

The invention provides a hybrid breeding method of high-quality and high-end beef new variety Low-li cattle, and relates to the technical field of breeding. The breeding method comprises the steps of breeding management, raising management and cow house management. Good beef variety Limousin cattle is introduced to be hybridized with Hezhou local yellow cows to obtain high-quality binary hybridized cattle, then another high-quality variety Lowline cattle are utilized to conduct ternary hybridization with the binary hybridized yellow cow to obtain high-quality beef new variety Low-li cattle, and then artificial breeding is conducted on the new variety Low-li cattle obtained by hybridization by stages to finally obtain the high-end beef. By means of the hybrid breeding method, the high-quality and high-grade beef new variety Low-li cattle have the advantages of coarse fodder resistance, cold resistance and high disease resistance, the dressing percentage and the pure meat percentage are both far higher than those of domestic cattle, through the utilization of hybridization advantages, the close crossing status quo of local cattle due to long-term closeness is changed, the variety of cattle is improved, and high-end beef needed by people is obtained.

Description

【Technical field】 [0001] The invention relates to the field of breeding technology, in particular to a hybrid breeding method for Louli yellow cattle, a new breed of high-quality and high-grade beef cattle. 【Background technique】 [0002] Cattle, also known as Chou, is a viviparous vertebrate of the genus Bovis and the family Bovidae. The ancestor of cattle is the wild aurochs. Beef is rich in protein, and its amino acid composition is closer to the needs of the human body than beef. It can improve the body's disease resistance. It is especially suitable for growth and development, postoperative, and post-illness people in supplementing blood loss and repairing tissues. Eating beef in cold winter can warm the stomach. , is a good tonic product in this season; beef has the effects of nourishing the middle and replenishing qi, nourishing the spleen and stomach, strengthening the muscles and bones, reducing phlegm and wind, and quenching thirst and saliva. It can be eaten by p...
