First, sow breeding
1. Step-feeding method: The sow feed is divided into five feed formulations in the five stages of pre-lactation, late lactation, mating, late mating and pregnancy. During the lactation period, the sows' backfat can be reduced by 30% due to the large amount of nutrients stored in the body during pregnancy and lactation. During this time, fat, protein and minerals are added to the feed formulation. Increasing the energy feed 1.26 megajoules per day after weaning can increase the number of litter piglets by one.
2. Cooperative sow farms: There are generally 1200 to 1600 sows on this farm, and there are eight shareholders. Each shareholder accepts all weaned piglets within one week of the sow, and they are raised in the nursery for one week before they appear. Follow all weaned piglets in the following week. This kind of field is an important part of all-in, all-out, and it replaces the way in the past without asking questions, which is conducive to improving the efficiency of feeding and management and thorough cleaning and disinfection of housing.
Second, piglet rearing
1. Individual Weaning Method: Weaned the heavier piglets in the nest 2 to 3 days in advance to allow the smaller piglets to eat more breast milk, thereby increasing the weight of the weaned piglets. Weaning weight was positively correlated with market weight. Weaning weights above 6.5 kilograms were less than 5 kilograms ahead of schedule and were over 7 days ahead of schedule.
2. Isolation and rearing methods: After weaning at 2 to 3 weeks of age, weaning piglets are kept in nursery houses away from the sows, which can reduce the number of diseases and increase the annual number of herds.
Third, fattening pigs
1. One-stop feeding method: Weaned piglets are transferred directly to the finishing house and raised to market weight. The advantages are rapid weight gain, reduced labor and transportation costs, and avoiding stress factors from the sow house to the nursery to the finishing house.
1 Increase market weight: Listing weight has increased from 100 kg to 114 kg. The slaughterhouse wants pigs that are heavy and do not accumulate too much fat.
Fourth, feeding and management
1. Computer records: More than 90% of pig farms use computers to record and combine production records with financial records, which is both convenient and convenient.
2. Controlling the environment: The method of controlling the odor of the pig farm is to improve the sewage treatment facilities, change the protein and mineral content in the feed, and add additives such as Yucca or enzymes to the feed.
