Daily ration for feeding beef cattle producing snowflake beef and concentrate supplement formula

Abstract

The invention discloses a daily ration for feeding beef cattle producing snowflake beef and a concentrate supplement formula. A daily ration formula is adjusted along the different growth stages of beef cattle, the feed and the concentrate supplement formula at different stages are adjusted to the requirements of nutrient substances in a growth stage, an earlier fattening stage and a latter fattening stage, the intake of nutritional ingredients such as protein, digestible nutrients and microelements in each stage is limited, and specific substances are additionally added, so that the production cost is lowered, the quality of the obtained beef is greatly improved and reaches level 3A of 'grading standard of snowflake beef carcass'.

Description

technical field [0001] The invention relates to a formula of a beef cattle ration and a concentrate supplement, in particular to a formula of a beef cattle ration and a concentrate supplement for producing 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 f...

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 the first-generation hybrid calves selected from Japanese Wagyu cattle and Holstein cows for feeding; patent application CN201210137480.7 discloses a fattening method and concentrate supplement for snowflake beef cattle, which is According to the different periods of raising BMY beef cattle, choose different ratios and dosages of supplementary concentrates and extra feeds such as salt and monensin to feed beef cattle. The BMY beef cattle are American Brahman cattle, Australian Murray gray cattle and native Yunnan Yellow cattle are obtained by three-way hybridization; in the above-mentioned literature, either intensive fattening is adopted, or different breeds are selected for crossbreeding, which leads to high production costs, and is limited by the shortage of cattle, which has become a bottleneck in 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 breeds and regional ecological environment and feed quality, copying this fattening technology is not ideal for Guizhou area; patent application CN201310563063.3 discloses a method of using Guanling cattle to produce snowflake beef, using Guizhou local breed Guanling Cattle are used as the basis for the production of snowflake beef. Through suitable fattening methods and fattening diets, snowflake beef that meets the 3A grade of the "Snowflake Beef Carcass Grading Standard" is produced. Although this method gives the formula of concentrate supplements for different fattening periods , nutrient level and premix composition, but there are no specific requirements on the formula of the diet, the dosage of supplementary concentrates, etc.
