The body weight of calves fattening calves law 180-200KG, fattening the entire 380 days. Fattening preparation, this stage time is 60-65 days, and dietary forage to concentrate feed ratio is 35:65, the crude protein level of 13%. Pre-fattening, time is 150 days, dietary forage to concentrate feed ratio is 35-45: 65-55, crude protein level of 12% -13%. Fattening mid-time of 90 days, dietary forage to concentrate feed ratio is 55-60: 45-40, crude protein level of 11% -12%. Late fattening time of 80 days, the dietary forage to concentrate feed ratio is 65-75: 35-25, crude protein level of 10%. In fattening preparation period, the main purpose is to adapt to environmental conditions are fattening calves and cattle during this period to get rid of parasites in vivo immunization work. Bred cattle fattening law continued fattening method - fine material type fattening fattening mode start weight 250-270KG, ages 12 - 14 months, fattening of the requirements of 10-12 months. Pre-fattening, fattening 2/3 time for the entire dry matter basis, feed forage to concentrate ratio of 60-65: 40-35 fattening late, time for the entire fattening 1/3 on a dry matter basis, feed forage to concentrate ratio of 75 -80: 25-20 fed ad libitum ways to better support group that should be used to fence fattening method. According concentrate type pattern are: strong growth in beef cattle period, increase the amount of feed into its growth advantage to play the greatest degree of beef cattle, feeding period to make the greatest possible reduction of cattle, reducing the need to maintain the consumption of beef, improve feed. Late centralized fattening Law - pre-more coarse material mode of this fattening mode, the pre-feed a lot of roughage, exercise bovine digestive organs, so that in the latter part has a larger intake and digestion, which can give full play Cattle compensatory growth characteristics and advantages, to obtain satisfactory fattening effect. Begin fattening weight 260-270KG, pre-fattening 150 days, fed quality hay, ammoniated straw, corn silage and other high-quality green fodder, just to make a little fine material. Mid 150 days, this high level of protein, and energy levels are relatively low, this period of growth since the compensation cattle, feed conversion, good weight gain, post-150 days, the meat quality of the protein levels are relatively low, The energy level is relatively high, in order to facilitate penetration of fatty deposits in the muscle and muscle fibers through to form the marbling.
