[0005] Because this technology in Japan limits the types of feed materials and the divided fattening period, the cost of feed and feeding (fattening cost) is very high. Although the research on reducing the fattening cost has always been a core topic, it has even suffered from Japan's accession to the WTO. Huge pressure on trade liberalization, but no breakthroughs have been made in reducing costs and further improving meat quality

Embodiment 1
[0041] Embodiment 1, fattening of castrated Chinese yellow cattle-Yanbian cattle (hereinafter referred to as "Yanbian cattle") male calves
[0042] Taking castrated Yanbian calves with an average age of 9.3±0.6 months, a weight of 270±12kg, and 3 months of age as an example, they were fattened according to fattening and weight gain procedure 1.
[0043] Step 1: Formulate concentrated feed formula and prepare concentrated feed
[0044] It can be found out from the nutritional requirement parameter table of fattening and weight gain program 1 that under the weight condition of 9-14 months of age, the nutritional standard of the concentrated feed that needs to be modulated is: crude protein (CP) content is 14.5%, digestible protein (DCP) content is 12%, total digestible nutrient (TDN) is 72%, calcium content is 0.60%, phosphorus content is 0.30%. According to this nutritional standard, formulate a concentrated feed formula (see the feed formula table) and prepare a concentrated ...
Embodiment 2
[0058] Embodiment 2, the fattening of castrated male calves of Anqin cattle (the hybrid offspring of Qinchuan cattle and Angus bulls)
[0059] Taking castrated male calves of Anqin cattle (crossbreed offspring of Qinchuan cows and Angus bulls) with an average age of 8.5±0.4 months, body weight of 262±18kg, and age of 3 months as an example, fattening was carried out according to fattening and weight gain procedure 2 .
[0060] Step 1: Formulate concentrated feed formula and prepare concentrated feed
[0061] Can find out from the nutrient requirement parameter table of fattening weight gain program 2, the nutrient standard of the concentrated feed that needs modulation in 9-14 month age stage is: crude protein (CP) content is 14.5%, digestible protein (DCP) content is 14.5%. 12%, the total digestible nutrient (TDN) is 73%, the calcium content is 0.70%, and the phosphorus content is 0.35%. According to this nutritional standard, formulate a concentrated feed formula (see the ...

Abstract
The invention discloses a fattening method for the cattle making snowflake beef. The nine month old stock calves of 270 plus or minus 30 kg weight are selected for fattening and breeding according tothe following fattening and weighting procedure 1 or the fattening and weighting procedure 2, and the fattening degree value is calculated according to the following formula: the fattening degree value is equal to the (weight / stature) multiply 100. When the fattening degree value is more than or equal to the fattening degree critical value of the cattle variety in a fattening degree critical valuetable, then the cattle can be put into market, and then the cattle which can make snowflake beef is obtained. By giving the nutrition requirement value and the forage feeding value in each fatteningstage, the invention integrates the deeper and difficult growth physiological rule of the bones, the muscles, and the adipose of the cattle, and the technologies of nutrition metabolizing and controlling organically, and simplifies into a forage prescription and the control of the forage taking value. The invention can naturally conduct regulating, and can ensure bones, muscles, and adipose to getmaximum development and aggradation during the peak period of the growth. The forage prescription can be changed freely by the executor of the invention according to the classification of the foragematerial and the price change, and the cost of the forage is controllable.
Description
technical field [0001] The invention relates to a fattening method for producing snowflake beef cattle. Background technique [0002] No matter at home or abroad, snowflake (high-density marbled) beef is regarded as high-grade or high-quality beef by the consumer market, with high added value, and has the characteristics of high input and high output in beef cattle fattening. [0003] It is unclear when the technique of marbled beef production was born, but what is certain is that the technique has a long history. With the continuous improvement of modern people's pursuit of beef quality, the technology used to produce marbled beef has also been continuously improved, from the earliest simple extension of fattening time to the later castration of bulls, and early restriction of nutritional intake by using compensation for growth physiological characteristics The technical form of "straight line fattening", "intensive fattening" and "modified fattening" has undergone several...
