One, pork The growth and development of pigs are characterized by slower growth in the early stages, faster weight gain in the middle period, and faster fat deposition in the later period. Under normal circumstances, the growth of fattening pigs 20-30 kg for the peak period of bone growth, 60-70 kg for the peak muscle growth, 90-100 kg for the accumulation of fat. The weight gain has a great relationship with variety and nutritional level changes. The peak growth period of the breed pig muscle is about 50 kg (3-4 months old), and with the increase of the age, it is 70-80 kg (4-5 months old) After that, the strength of fat growth has increased significantly and gradually exceeds the intensity of muscle growth. The body begins to deposit a large amount of fat. The slaughter benefit is best when the weight reaches 90 kg. Local precocious varieties are most suitable for slaughter when they weigh about 75 kg. At this time, the meat quality is good, and the slaughter rate is also high; the slaughter rate is 7-8 months (90-100 kg) slaughter rate for the two- or three-way crossbred pigs that use the local pig as a female parent and a male lean pig as a parent. optimal. Second, beef cattle The daily gain of beef cattle is faster and slower with age. Bulls generally grow faster than their calves, and calves grow faster than cows of the same breed. Different feeding methods have different weight gains: In the case of house feeding, young calves gain weight faster than calves and heifers, and they have good meat quality and low feed consumption. In free-range breeding, the calf's weight gain and feed repayment are relatively reduced, while the young female calf and calf's weight gain is faster, and the fat and meat are more tender, but feed consumption is more. Compared with free-range feeding, the daily weight gain increased by 19.6%, feed consumption decreased by 26.3%, and weight gain cost decreased by 19.6%. Beef cattle fattening, in the vigorous growth period of 10-18 months, through the use of matching feeding techniques for 80-150 days of concentrated fattening, when the weight reached 450-500 kg, the best slaughter benefit. The fattening of old cows can only allow them to recover the public opinion in the short term, and it is impossible to have greater weight gain and the benefits are relatively poor. Experiments show that the yaks have the fastest muscle growth in the first 6-8 months after birth. Later, with the increase of body weight and age, muscle growth slows down and feed utilization rate gradually decreases. In the latter half of the growth period, the weight of beef increases by 18% for every 100 kilograms of body weight, 42% for every 100 kilograms at 2 years old, and 60% for every 100 kilograms at the age of 3. Therefore, the best economic benefits for the hybrid cattle are 1.5-2 years old. Third, meat sheep The production of mutton sheep is mainly based on grazing and can also be fed. Sheep are fast growing from birth to 12 weeks. It has been determined that sheep can grow at a daily weight of 170 grams during the fast growing period; a sustained growth period of 12-30 weeks and an average daily weight gain of 135 grams. The cumulative growth is still on the rise. Most sheep have the fastest weight gain during 7-9 months of age. Sheep gained about 40 kg in 9 months and about 35 kg in meat goats. Therefore, we should grasp the early growth of mutton sheep. Fourth, meat dog Hybridized improved dogs mostly adopt captive breeding methods, because the activity of meat dogs is small, and the energy consumption in the body is small. Generally, fattening to 4 months of age, weighing about 20 kilograms, can be slaughtered. At this time, the meat dog grows fast, the feed conversion rate is high, and the meat quality is good. If the feeding time is too long, the slow growth of the meat dog is not effective.
