New U.S. Pig Breeding Method

l. Individually weaned: The heavier piglets in the nest are weaned 2-3 days in advance, so that smaller piglets have the opportunity to eat more breast milk, thus achieving a larger weaning weight. According to studies, piglets weighing more than 65 kg at weaning can reach market weight 7 days earlier than those with weaning weight less than 5 kg. 2. One-for-one feeding method: The weaned piglet is transferred from the sow house to the finishing house and raised to the market weight. This reduces the traditional link from the sow house to the nursery house and avoids some of the stress reactions that result from this. The main advantages of this method are faster weight gain, lower labor costs and transportation costs. The disadvantage is that the utilization rate of the pig house is low and it is not possible to do as many households as possible. One-for-one feeding methods also require better insulation performance in the finishing house, and the breeder has a higher level of technology. 3. Isolation and Feeding of Weaned Piglets: The practice is to wean the pigs at 1-2 weeks of age and keep the weaned pigs on a nursery farm far from the sow farm in order to reduce vertical transmission of certain diseases from the sows to the piglet. Isolation and feeding increases the number of litters per sow per year per year per litter, but may reduce the number of litters and litter size in the next litter. 4. Cooperative sow farm: This practice is a sow farm with 1200-1600 sows in several growing farms. Generally there are 8 shareholders in each sow farm, depending on the piglet's stay in the nursery. Each shareholder will receive all weaned piglets produced by the sow farm within a week. When these pigs leave the nursery, the growing farm will receive another batch of all piglets produced within one week from the sow farm. The cooperative sow farm is an important part of the all-in, all-out growing pig farm. And all-in and all-out type is replacing more and more pig farms in an uninterrupted manner. This approach is conducive to improving the management efficiency and implementing more thorough cleaning and disinfection between the two batches of pigs. 5. Sow-feeding methods: Sows consume a large amount of nutrients in the body during pregnancy and lactation, mainly fat, protein and minerals. In the first few weeks of lactation, the sow's backfat can be reduced by 30%. In order for the sow to return to estrus, the nutrient reserve must be quickly rebuilt. The sow stage feeding method includes at least 4 types of feed: post-lactation material, pre-match material, post-match material, and post-pregnancy material. Increasing the intake of 300 kcal per day after weaning can increase the number of litters by about one. The added energy must be in the form of starch. Glucose produced from starch stimulates ovulation. Organic trace elements are also conducive to recovery of trace element reserves in sows. 6, increase the weight of the market: the market weight has increased from 100 kg to 114 kg. Slaughterhouses are willing to weigh more pigs in order to increase processing efficiency. Modern pig breeds can also achieve larger body weight without accumulating excess fat. 7. Detailed records: More than 90% of pig farms have adopted computerized recording methods. Producers will need to combine production records with financial records. 8. Environmental control; The environmental problems caused by the pig industry are mainly odors. Measures to control odors include installing expensive sewage treatment facilities, changing the content of protein and minerals in feed, adding additives such as Yucca phytosterols or enzymes to feeds, and so on. Many pig farms take legal and moral responsibility for environmental protection.
