Method for fattening Sinan cattle used for producing snowflake beef

Abstract

The invention discloses a method for fattening Sinan cattle used for producing snowflake beef. The Sinan cattle of native breed in Guizhou is used as the base for producing snowflake beef, fattening diet formula and feed nutrition are improved by a specific 'three-phase type' fattening mode, the cattle weight increasing speed is obviously improved, and the production cost is reduced. The obtained beef has uniform marbling, the muscle is cherry-red, the fat is white, and the beef quality is greatly improved, reaching the extra grade standard in the 'beef quality grading' published by Ministry of Agriculture of the People's Republic of China. In addition, the method has the advantages that the method is simple and feasible, cattle sources are rich, feed cost is low, and operation is flexible. The current situation of depending on foreign cattle breeds or crossbreeds to produce snowflake beef can be changed, and local economic development and technical improvement are promoted.

Description

technical field [0001] The invention relates to a beef cattle fattening method, in particular to a beef cattle fattening method using Sinan cattle to produce snowflake beef. Background technique [0002] With the development of the national economy and the improvement of people's living standards, great changes have taken place in people's consumption structure, which has shifted from the satisfaction of quantity to the demand of quality, and the demand for the quality of beef and its products is constantly increasing. The document "Safety Production and Quality Control of South German Beef" (Zhang Defu, Xia Weimin, Shanghai Animal Husbandry and Veterinary Communication, 2007, 2:73) reported that my country's beef production ranks third in the world at present, but it has always failed in the international trade arena. It plays an important role, the reason is that my country mainly produces ordinary beef, and currently only a few companies have the ability to produce high-gr...

Problems solved by technology

[0005] At present, the cattle breeds generally used in the domestic production of snowflake beef are Wagyu, Angus, Simmental, etc. or their hybrid offspring with local yellow cattle, such as a hybrid rich in snowflake marbling meat quality disclosed in patent CN201210366373.1 Wagyu feeding method, which adopts Japanese Wagyu cattle for feeding and Holstein cow for feeding; patent application CN201210137480.7 discloses a fattening method and concentrate supplement for snowflake beef cattle, which is based on BMY At different periods of beef cattle feeding, different ratios and dosages of concentrate supplements and other feeds were selected to feed beef cattle. The BMY beef cattle were obtained from the three-way crossbreeding of American Brahman cattle, Australian Murray gray cattle and local yellow cattle in Yunnan; the above In the literature, either the intensive fattening feeding method or the selection of different breeds for hybridization lead to high production costs, and are limited by the shortage of cattle, which has become a bottleneck for the development of snowflake beef production

[0006] Patent application CN201210064613.2 discloses a fattening technology of snowflake beef produced by Yunnan yellow cattle. The feed and formula are adjusted according to different fattening stages, and the protein, trace elements, and digestible nutrients in the supplementary concentrate are required. Due to the differences in species, regional ecological environment and feed quality, copying this fattening technology is not ideal for Guizhou
