Picture production techniques of high-grade beef is what - beef cattle - goats - Meat - Focus ...
The production of high grade beef cattle, which in tenderness, flavor, juiciness and other major targets, the level required to achieve the required standard. High-end beef cow body mainly refers to the meat on the inside and outside the eye muscle (the longissimus muscle) and the arm of meat, the four parts of the short loin. This four-part weight of the meat about 5% of live weight beef -6%, or fattening cattle before slaughter weight of 500 kg, then high-grade beef is about the four parts 25-30 kg. per kilogram of high quality beef can be sold for luxury hotels in Beijing, 90-100 yuan. In other words, a high weight of high-grade beef accounts for only 5% -6%, while its total output value has accounted for a cow 46% -47% output, the economic benefits of the high and broad prospects for development can be imagined, summed up the experience at home and abroad, high-grade beef cattle fattening techniques are: (1) strict control requirements of beef cattle fattening selected age 6 months age weaned calves, weighing 200 kg, fattening to slaughter 18-24 days of age, more than 30 days or more, usually not the most high-grade beef production. (2) strict fattening cattle to slaughter weight of 18-24 days before slaughter should reach 450-500 kg live weight or more, there is no such live weight before slaughter, beef quality up to and asked to reach a certain weight before slaughter, the two are indispensable. (3) select high quality products in China is currently no specialized beef cattle breeds. fattening the best selection of high-grade beef cattle breeds of foreign domestic cattle bulls and bull hybrid generation. Hybrid generation of strong heterosis of beef cattle, physical big, fast growth, high weight gain and beef quality, a higher proportion of high-quality meat. In addition, varieties of cattle breeds in China, there are some varieties of meat production performance is also very prominent, for example, Qinchuan After 30 years of systematic selection, and its size has gradually changed from the Battle with the meat-type, equivalent to the average level of outstanding foreign, other varieties of cattle breeds of meat also has good performance, can produce a high-grade beef. (4) General feeding stage (for 4 months) of the feed at this stage to roughage-based diet, concentrate 25% of total diet; dietary crude protein content of 12%; daily feed intake per cow is about 4 kg of dry matter. (5) strength of fattening stage (time of 8 months) If you plan to fattening cattle feed to 18 months old, weighing about 500 kilograms slaughtered after 8 months of feeding should be in this way: 1,250-300 kilogram of body weight phase, the proportion of the diet 55% concentrate, containing 11% crude protein, dry matter intake per head of cattle at 6.2 kg, 55% of feeding period, average daily gain of about 0.7 kg . 2,350-400 kilogram of body weight phase, the proportion of the diet 75% concentrate, containing 10.8% crude protein, dry matter intake 7.6 kg per head, feeding period of 45 days, average daily gain 1.1 kg. 3,450 - stage of 500 kg body weight, the proportion of dietary concentrate 75% -80%, with 10% crude protein, dry matter intake per head of cattle at 7.6-805 kg, 1.1 kg daily gain. This stage is also called meat quality stage, fattening cattle carcass muscle fibers in the mixture of fatty meat can form marbling, and is correct at this stage of the breeding relationship great. (6) is a scientific and standardized management of beef cattle breeding shed or fences to be taken keeping. homes When fed to a cow tethered a fixed, the reins should not be too long to limit the excessive movement caused by consumption of free energy. fence when feeding, fattening cattle within the fenced backyard, about 15 per column, each of the first possession area of 4-5 square meters, ad libitum, free access to water. the proportion of dietary concentrate to rise to above 75%. at this time to pay attention to fattening cattle at any time to digest the situation, with or without belly up, or diarrhea, if it is found to timely treatment, adjust dietary structure and Feeding Amount. fattening bulls can be castrated or castrated before, where a plan to slaughter bulls 18 months of age, to not castrated as well, rapid weight gain, fattening effect. In addition, mature beef cattle production in the high-end processing is an indispensable link. just slaughtered, high acidity, fleshy and stiff, poor taste, not reach the requirements of high-quality beef. effective way to solve this problem is to hang after the carcass splitting row of acid treatment, acid discharge temperature requirements 0-4 degrees Celsius, usually 7 days hanging around time. This beef after full maturation, a number of enzymes within the muscle under the action of the series of biochemical reactions that decrease the acidity of the meat, greatly improves tenderness. So high must ensure that this part of beef production. Currently self-employed and fattening beef cattle farm in rural areas more than the absence of this link, and bleeding on the ground, slaughtering and skinning is also very unhealthy and affect sales. To this end, Under the current conditions in rural areas, only organize themselves into joint-stock production cooperatives, relying on the accumulation of funds or bank loans, the establishment of meat processing and cold storage, mining can guarantee the implementation of this part.
