In recent years, with the popularization and application of cattle cold-finishing technology and straw cattle-raising technology, the cattle industry has evolved from traditional service to meat use. Beef production has gradually become a scale, and short-term compulsory fattening of shelf cattle has been widely used. Market supply. However, due to the small per capita grassland area in China, the number of cattle produced on the shelf is insufficient, and in addition, this type of fattening method has a long period, resulting in a low slaughter rate and low economic efficiency. At the same time, with the improvement of national living standards, the demand for high-grade beef is also increasing, and the application of Yak linear fattening technology can better make up for the above deficiencies and defects. Yak linear fattening has four advantages: First, it shortens the production cycle and improves the slaughter rate. The second is to improve the meat quality to meet the market demand for high-grade beef. The third is to reduce the cost of raising and increase the economic efficiency of beef cattle production. The fourth is to reduce the amount of livestock carried by the grassland and obtain higher ecological benefits. Yak linear fattening mainly includes the following technical steps:
1. Selection of fattening yak breeds Select good bulls such as Charolais, Simmental, Limousin, or Black-and-white flowers to cross-breed with local cows to improve the hybrid yaks.
2. Feeding and management of yaks Eat enough colostrum. Meat yaks are generally naturally breastfeeding. Calves should be fed colostrum 1 to 1.5 hours after birth and they must eat enough food within 7 days. Because colostrum helps in antibacterial, diarrhea and fecal nutrition, it is extremely rich in nutrients. At the same time, add some vitamin A, vitamin D and vitamin E. Feeding management. Early feeding of calves is very important. At the age of 1 week, training and drinking warm water began. In order to promote the development of the rumen of calves and supplement the nutrients needed by calves, feed some green and coarse fodder concentrates earlier: Generally, begin the training at the age of 10 to 20 days, and concentrate the condiments into porridge when starting the training. Add a little milk, feed 10-20 grams on the first day, and gradually increase the amount of feed; 10 to 20 grams of carrots are crushed daily starting at 20 days of age, and gradually increase the amount of feed; after 30 days of age, the mechanism of the hay is set in the column. Its feeding; 60 days of age began to feed silage, the first feeding amount of 100 to 150 grams. As calf intake increases, adequate drinking water must be guaranteed. Calves and cows need to be kept in separate rows, and breastfeeding is regularly released. The yaks must exercise moderately, with the mother grazing in the pastures near the cowshed, appropriate slowing down the speed of grazing, and ensuring the rest time. Calves were weaned at 135 days of age.
3.Fattening technology Before the yaks are transferred into the finishing houses, they are sprayed with 2% caustic soda solution on the ground and walls of the finishing houses. The apparatus is sterilized with 1% benzalkonium bromide solution or 0.1% potassium permanganate solution. Yaks are fed to fattening quail after weaning. The fattening pod is a standardized plastic film shed, and the lining temperature should be kept within a range of 6°C to 25°C to ensure a cool winter and cool summer. In summer, shade sheds should be used to maintain good ventilation. When the temperature is above 30°C, measures should be taken to prevent it from cooling. In winter, double-layer plastic film shall be applied. Ventilation and ventilation shall be taken care of, and harmful gases such as ammonia and carbon monoxide shall be promptly removed. According to the order from big to small, the cattle body should be tied, fixed and positioned. The reins should be 40-60 cm. Feeding for fattening cattle. Pasture, crop stalk, blue (half-dried) straw, ammoniated stalk, micro-storage stalk, root tuber and vine, distiller's grains, beet pulp, corn, rapeseed cake, sorghum, sunflower cake, wheat bran, bean cake, cottonseed cake , salt, minerals, additives, etc., can be fed fattening calves. The calves were transferred to the rearing room and fed for 10 to 14 days to adapt to the environment and feed and gradually transition to the fattening diet. In summer, lush grasses are the best season for grazing. They use the advantages of high nutritional value, good palatability, and high digestibility of wild grasses and use grazing and fattening methods. When the temperature exceeds 30°C, pay attention to the heatstroke and reduce the temperature. You can adopt the nighttime grazing method to make full use of the conversion of forage grass into beef, reduce the cost of raising and increase the economic benefits. Grazing during the day in spring and autumn, supplementing a certain amount of green (half-dried) storage, ammoniating, micro-storage of straw and other roughage and a small amount of fine material at night. In the winter, it is necessary to add a certain amount of concentrate, and appropriately increase the energy feed (cotton-seed cake, etc.) to improve the cold resistance of the calves and reduce the proportion of energy in the basal metabolism. The formula of the diet formula for fattening cattle is as follows: Formula One: 35.2% of cornmeal, 5.9% of bean cake, 29.3% of distiller's grains, 29.3% of hay, 0.3% of salt, plus 1% of compound additive; Formulation 2: 19.6% to 22.4% of concentrate material, Distiller's grains were 26.4% to 27.1%, hay 8.4% to 9.1%, micro straw 42.2% to 44.2%, plus 1% of composite additives. Management of fattening cattle. Feeding fattening calves feed three times a day, feeding grass fodder, feeding ingredients, and finally drinking water. Be careful not to feed iced feed and drink cold water, and drink warm water in winter. Drinking water is usually done 1 hour after feeding. Fattening cattle 10 to 12 months of age with "Bombycide" or "levamisole" an insect. “Bulk killer†requires an oral dose of 0.1 g per kilogram of body weight per dose; “Levamisole†has an oral dose of 8 mg per kilogram of body weight per cow. At 12 months of age, “synthetic salt†is used to stomach 1 time, and the oral dose is Head cattle 60 to 80 grams.Daily daily swab cattle body 1 times, in order to promote blood circulation, increase appetite, keep the body of cattle health, feeding utensils also often wash and disinfect.Fattening cattle to do a good job of disease prevention and control, often observed cattle mining Food, drinking water and ruminants were found to be promptly treated.4 Timely slaughter When fattening cattle aged 18-22 months, weighing 500 kg, and full body muscles, subcutaneous fat can be slaughtered.
Specialist devices for patients after surgery. It is a kit set, including two radial connectors (one blue and one white, also them as pagoda connector), one cornical connector (transparent), and three threaded luer locks. Six of them are universally used to slove all the turing connection problems after surgery. Using them, no need worrying about leakage, disconnection, size dismatching and others. For blue pagoda connector, it suits with the tubing diameter more than 16Fr, and the white one are applied with the tubings from 3Fr to 16Fr.
The urine bag set consists of A drainage bag and A suction device. Qhy-a is the single drainage bag, and qhy-b is the drainage bag + suction device. The drainage bag consists of the bag body, catheter, lifting lug, joint, guard cap, drainage port, drainage bottom plug, anti-reflux device, and current limiting clip.The suction device is composed of negative pressure bottle, drainage tube joint, suction tube joint, suction connection pipe, automatic drainage device, drainage port and bag body.Should be sterile.
