At present, the low slaughter rate, low carcass weight, low lean meat ratio, and unreasonable price of pigs and grains in the development of swine production seriously restrict the development of scale and intensification of the aquaculture industry. Local pig breeds in China are characterized by strong fertility and resistance, good flesh quality and gentle temperament. They can make heavy use of green roughage. However, the growth is slow, the slaughter rate is low, and the lean meat is low. The three-way hybrid pig has the characteristics of fast growth, high feed utilization rate, high lean meat percentage, and obvious economic benefits, and is suitable for promotion. Sanyuan pigs have internal Sanyuan pigs and foreign Sanyuan pigs. The internal three-way hybrid pigs mainly use female pigs from China's local breeds as female parents, and use the hybrid pigs whose foreign meat-type pigs are male as female parent, and then use the foreign pigs of imported meat breeds as terminal male parents. Produced by hybridization. All three yuan outside the use of exotic varieties of hybrid.
The breeding of Sanyuan pigs must master and utilize the growth and development of pigs, control the nutrition and environmental factors, adopt advanced feeding and management techniques, increase daily weight gain, reduce feed consumption and production costs. Focus on the following four production technology measures.
Buying pigs and Miao pigs in swine production, especially in the rearing stage of the swarm, often occur when the boar meets the mother to stay and see the seedling bite, and cannot be carefully selected. This is inconsistent with the requirements for scientific swine breeding. of. The following points must be observed when selecting breeding pigs and Miao Pigs: First, the purpose of introduction must be clear; Second, the introduced pig species must be adapted to the local environmental conditions; Third, it is necessary to understand the genealogy; Fourth, it is necessary to identify the good appearance; Pigs should meet the characteristics of breeds, and hybrid pigs should have good body conditions. The fifth is better appetite.
Post-weaning Piglet Management
1. Appropriate dietary nutrient levels The amount of crude fiber in the diet of hogs affects the daily gain and carcass leanness. Every 1 percentage point increase of crude fiber in the diet can reduce organic matter (or energy) digestibility by 2 percentage points and crude protein by 1.5 percentage points, resulting in a reduction in feed intake, a decrease in daily gain and thinning of back fat, and a reduction in lean meat percentage. rise. It is recommended that when crude dietary protein and digestive energy levels are normal: 20-35 kg body weight, crude fiber content is about 5%-6%, and 35-90 kg stage is 7%-8%, but should not exceed 9%.
2. Care at birth: The main task of this period is to ensure that the Miaozhu is born safely, to prevent the premature death of newborn pigs, suffocation, frozen death, and difficult sows of the sow, and to prevent and treat certain diseases of the Miao pig after birth. The Miao pig should be eaten in time. Milk, for the Miao pig to create a suitable temperature and humidity, clean and comfortable living environment.
3. Feeding and management after (twenty) days after birth, this period is when the peak of sow's lactation is about to decline, and the growth of piglets is faster, and the supplementary feed phase is needed. The main task is to allow the Miao Pig to feed the full-price nutritional feed as soon as the sow's lactation is reduced, supplementing the lack of sow lactation and the need for rapid growth of the Miao Pig. Days of care, especially care within three days after birth, the main task of this period is to fix the nipple, prevent the sow from being crushed or stepped to death, observe whether the piglet is diarrhea and other diseases, and timely treatment.
4. Feeding and management during weaning, after the weaning pig has been weaned, the nutrients for growth and development have changed, the physical aspects of the lead period have changed greatly, the resistance and immunity are reduced, and the disease is easy to attack. Therefore, it is necessary to create a good one for the Miao pigs. The environment and configuration of a reasonable feed for feeding.
5, feeding and management after weaning, the main task of this period is to maintain the growth rate of Miaozhu not affected, to protect the Miaozhu not sick, to prepare for fattening.
6, feed formulation: 20 ~ 60kg: corn 53%, fine rice bran 10%, high quality fish meal 2%, 16% soybean meal, wheat bran 15%, calcium hydrogen phosphate 1.5%, 0.23% stone powder, salt 0.19%, additive 2.08% ( Including 486 mg of ferrous sulfate, 505 mg of zinc sulfate, 19 mg of copper sulfate, 6.8 mg of manganese sulfate, 0.24 mg of potassium iodate, 1.0 mg of sodium selenite, and various vitamins: Vitamin A 1230 IU, Vitamin D 189 International Unit, Vitamin E 10 International Unit, Vitamin K 2.5mg, Vitamin B1 1mg, Vitamin B2 2.5mg, Niacin 13mg, Pantothenic Acid 10 mg, Biotin 0.09 mg, Folic Acid 0.57 mg, Vitamin B12 10 μg and Disease Prevention Promote the drug flavomycin 20mg. Less than 2.08%, with rough to make up).

Collagen is the most abundant protein in mammals, accounting for 25% to 30% of the total protein. It is widely present in all tissues from the body surface of lower vertebrates to mammalian bodies. Collagen monomers are long cylindrical proteins with a length of about 280 nm and a diameter of 1.4–1.5 nm. It consists of 3 polypeptide chains that are supercoiled around each other.
