(1) The necessary conditions: Water quality, air, feed, additives, veterinary drugs, and final products meet national or local pollution-free standards, and the production process is conducted in accordance with pollution-free production regulations.
(2) The source of piglets: The first is to purchase binary cross-breed sows at breeding pig farms that have obtained the “Plant Production and Marketing Permit for Breeding of Breeding Livestock and Poultryâ€, and to select terminal fathers for the production of three-way hybrid pigs; second, to obtain “seed breeding animalsâ€. The second-tier breeding ground for poultry production and operation permit purchases three-way crossbred pigs for breeding. Piglets require strong physique, light hair, well-balanced development, flexible movement, and strong appetite.
(3)Fattening technology The first period of fattening (60 kg of weaning), adopting a higher level of nutrition for pigs to feed freely, the digestibility per kilogram of dietary energy is 13-13.39 kJ, the crude protein is over 16-18%; the late fattening period (60 kg to the slaughter), feed intake is 85-90% of the free supply, dietary digestibility energy is 12.55-13 kJ, crude protein is 12-14%, and daily weight gain is over 600 g. Meat ratio 3.2-3.5:1.
(4) The management of finishing pigs is fed 2-3 times a day, each feeding 1 kg of feed water and 2.5-3 kg of water. The herds were reasonably grouped according to their source, body weight and eating habits, and each group was generally about 10 heads. Suitable temperature for pigs is 15-26°C and 60-70% humidity. Keep the pig house clean, fresh air and proper lighting. 15-60 kilograms of pigs occupy 0.8-1 square meters, and more than 60 kilograms are 1-1.2 square meters per head. The pig house is regularly sterilized and epidemic prevention is strictly conducted according to the immunization program. Timely slaughter, generally 90-110 kg slaughter is appropriate.
