Grazing and supplementary feeding combined beef cattle breeding method

Abstract

The invention provides a grazing and supplementary feeding combined beef cattle breeding method. The method is characterized by adopting the way of combining supplementary feeding and grazing, prolonging the grazing time during summer and autumn with no or little supplementation of feed, and additionally and substantially supplementing feed during spring and winter. The feed comprises green feed and mixed feed, wherein the green feed refers to various herbage at grassy hills and slopes, and consists of crop straw, coarse cereals, artificially planted herbage like Lolium multiflorum, Purus frumentum, sorghum sudan grass, medicago sativa, and Trifolium repens, etc., and the mixed feed is proportioned according to the needs of the beef cattle feeding stage. The breeding method provided by the invention combines grazing and supplementary feeding, and has the characteristics of high meat-production rate and high dressing percentage.

Description

technical field

[0001] The invention relates to a livestock breeding method, in particular to a beef cattle breeding method combining grazing and feeding. Background technique

[0002] Traditional beef cattle are mostly raised by grazing, but the effect of increasing meat is low. There is also the use of drug treatment to increase the meat of beef cattle quickly, but it often has a negative effect on the growth of beef cattle and the effect of increasing the meat is not very good, and the meat quality is not good. In particular, Jianyang big-eared cattle have fast growth and strong fecundity, and their main economic traits have stable genetic performance. If they are only raised by grazing, their growth rate will be relatively slow and their meat increase rate will be slow. If they are only raised by feed, their Feeding costs are high. Existing pure fodder raising method exists the problem that is difficult to popularize in vast rural pasture area. Contents of the invent...

Examples

Embodiment Construction

[0012] The feeding method of the present invention combines supplementary feeding with grazing, prolongs the grazing time in summer and autumn and does not supplement or less feed, supplements and supplements more feed in spring and winter, and the feed includes green feed and mixed feed, green feed Refers to all kinds of pastures on grassy slopes, which are composed of crop stalks, miscellaneous grains, and artificially planted pastures such as ryegrass multiflora, Mexican corngrass, sorrel grass, sudan grass, alfalfa, white clover, etc.; The mixed feed is proportioned according to the feeding stage of the beef cattle.

[0013] The mixed feed formula: by weight percentage, consists of 35% corn, 7% soybean meal, 28% wheat bran, 15% alfalfa meal, 12% wheat bran, 2% calcium hydrogen phosphate, and 1% salt.
