Breeding method and supporting fattening feed for a new breed of sheep for meat

Abstract

The invention discloses a method for raising a novel strain of meat sheep. The method includes carrying out crossing on Hu sheep and Australian white sheep to obtain a first crossed generation of flock of sheep; carrying out crossing on high-quality ewes of the first crossed generation of flock of Australian-Hu sheep and Charolais sheep to obtain a second crossed generation of flock of sheep; carrying out athwart crossing and fixation on the second crossed generation of flock of sheep; appropriately introducing 'new blood' into the second crossed generation of flock of sheep to prevent inbreeding depression; ultimately raising the novel strain of meat sheep by means of strict feeding and management and ideal typical individual selection. The Hu sheep is used as a female parent, and the Australian white sheep is used as a male parent. The high-quality ewes of the first crossed generation of flock of Australian-Hu sheep are used as female parents, and the Charolais sheep is used as a male parent. The invention further discloses matched fattening fodder for raising the novel strain of meat sheep. The method and the matched fattening fodder have the advantages that diarrhea of lambs in weaning periods can be reduced by the aid of the fodder, body physiological functions of the sheep, the growth rates of the sheep in later periods and fodder digestion and utilization can be improved, the method and the matched fattening fodder are matched with modern genetic breeding and reproducing techniques, and accordingly the novel strain raising success rate can be effectively increased; the meat performance of the novel strain of the meat sheep raised by the aid of the method and the matched fattening fodder can be improved on the basis that the high reproductive capacity of a variety of the Hu sheep is maintained.

Description

technical field [0001] The invention relates to a method for cultivating a new strain of livestock and poultry and a matching fattening feed, in particular to a method for cultivating a new strain of meat sheep and a matching fattening feed. Background technique [0002] my country is a big sheep raising country, and the number of sheep and sheep products ranks among the top in the world. In recent years, with the rapid development of the national economy and the continuous improvement of people's living standards, people's consumption of mutton has continued to increase. The development of large-scale sheep raising is an inevitable trend in the development of the modern mutton sheep industry. [0003] Hu sheep is one of the important livestock in the Taihu Plain. It has the advantages of early maturity, estrus in four seasons, multiple births a year, multiple lambs per litter, and good lactation performance. However, compared with the world's best meat sheep, the meat produ...

Problems solved by technology

[0003] Hu sheep is one of the important livestock in the Taihu Plain. It has the advantages of early maturity, estrus in four seasons, multiple births a year, multiple lambs per litter, and good lactation performance. However, compared with the world's best meat sheep, the meat production performance of Hu sheep is not high. , can not meet people's growing consumption demand for mutton

At present, my country has not yet cultivated a recognized breed of specialized mutton sheep, and there is still a big gap between the existing mutton sheep and foreign breeds

[0004] In addition, strengthening feeding management is also an important technical measure to consolidate and improve the breeding results, especially the newborn lambs grow and develop rapidly after weaning to six months, and it is also a period of frequent occurrence of diseases, which requires improved nutrition as a guarantee , otherwise these breed characteristics will be difficult to give full play to
