Energy: Weaned piglets are extremely deficient in energy due to stress during weaning, and their digestive energy should be no less than 3.5 kcal/kg. In energy composition, energy gradient supply is the most important. Protein: The piglet diet protein should be within 18%. The lower the crude protein, the lower the diarrhea rate. In pig milk, the dry matter is about 20%, including 9% fat, 5% lactose, 5.5% protein, but essential amino acids. Can't be low. Acidity : The piglet feed is currently controlled by acidity to control the alkali storage of the feed, preferably around 20, which can fully activate the digestive enzymes in the pigs, stimulate the gastric motility, and improve the digestion ability of the piglets on plant proteins. It can kill pathogenic E. coli and Salmonella infected by oral cavity and reduce diarrhea. Diarrhea control technology: Most suckling pigs use high-digestibility materials to reduce the use of plant protein such as soybean meal. This technology controls diarrhea, but after weaning for 1 week to 2 weeks, the corn-soybean-type diet will change. There is a problem of reduced feed intake, diarrhea, and slowing of growth. Some manufacturers have added high-zinc and high-dose antibiotics to reduce diarrhea, but seriously affect the feed intake and pig intestinal development after pig weaning. The subsequent growth has a great impact; some companies enhance their digestive capacity by increasing the endogenous enzyme activity of piglets, and the feed intake after weaning is gradually increased. Material type: powder and dry material have their own advantages, but the higher the grade of the material, the less easy to granulate, mainly the high content of oil and fat, and the granulation is easy to cause vitamin damage and cause antibodies even at low temperature granulation. The activity is reduced, so the high-grade teaching materials such as artificial milk and milk substitute are powdery, but many pig farm owners like pellets, think that waste is less, save feed, but the nutrition is discounted, just like the milk powder that the baby eats. This view must be changed. Dry feeding or wet feeding: wet feeding is more suitable for pig's digestive physiology, because 80% of breast milk is water, wet feeding weaning weight gain is better than dry feeding, but many pig farms think it is too troublesome, if dry feeding, should be less It is better to feed more meals. Use of plasma: In the epidemic of swine fever in 2005, many people blamed the culprit on the use of homologous proteins such as pig plasma. At that time, the positive rate of blue ear disease and circovirus was not very high. There are some risks in using plasma. Now the positive rate of blue ear disease and circovirus is more than 90%. There is a lot of problem without using plasma, because many antibodies in plasma contribute to the success of early weaning. There is a large pig farm that was stable with plasma pig farm. Later, Obey the experts suggest that the breeding farm should not use plasma and other homologous proteins to control the spread of the disease. After stopping the plasma, it will not be long before it has a high fever. Of course, the plasma must use the products of large companies with advanced production technology, and most of the plasma production companies. Biofilm filtration, high pressure homogenization, and instant ultra-high temperature sterilization to kill microorganisms to ensure the biosafety of plasma. Small companies do not have biofilm filtration technology, resulting in ash content of more than 15%, IGg antibody less than 14%, salt 6% or more, large companies with biofilm filtration, plasma ash is about 10%, IGg antibody is not low. At 18%, the salt does not exceed 3%. Tin Lead Copper Alloy Wire,Cored Alloy Wire,Welding Rosin Core,Joined Metals Solder Special Alloy NINGBO XIHAN TIN SOLDER CO.,LTD. , https://www.soldertop.com
