2, as early as iron. After birth, piglets need to consume 7 mg of iron daily, while only 1 mg of iron can be obtained from breast milk. If the piglets intramuscular injection of 1 ml of ferritin, the effect is better.
3. To increase the birth weight and weaning weight of piglets. The bigger the piglet's primary weight, the better it is to raise, the faster it gains weight, and the weaner weight is greater. According to the experiment, weaning pigs with large weaning weights were reduced by 1-2 months compared with the weight of weaning pigs under the same feeding conditions.
4, provide suitable temperature and humidity. The high temperature and humidity in the pig house will lead to a decrease in feed intake and a decrease in daily gain. If the temperature is too low, the energy consumption is large, the feed intake is large, and the feed payment is low. The pig house temperature should be controlled at 20-30°C for piglets, 15-20°C for pigs, and 50-55% humidity.
5, provide adequate clean drinking water. To ensure that fattening pigs have a strong metabolic ability.
6, feeding to take "four changes." The number of feedings will be fixed, the feeding time will be determined, the feeding amount will be set, the feeding standards will be set, and the moisture-removing and seasoning materials will be fed to the pigs as dry powder. The piglets were fed 5-6 times a day, medium pigs 4-5 times and big pigs 3 times. The feeding time should be relatively fixed every day. The amount of feed fed should be balanced each time.
7, a reasonable breeding density. It is appropriate to occupy 0.8-1 square meters per pig. 3-4 months old pigs accounted for 0.6 square meters, 4-6 months of age accounted for 0.8 square meters, 7-8 months of age 1 square meter. Each pig occupies 1.1-1.2 square meters in summer and 0.9-1 square meters in winter.
8, the implementation of the same nest breeding. Piglets from birth to fattening slaughter, the implementation of the same litter of the original circle feeding method, than after weaning transfer polymixing method is effective. Due to the reduction of stress stimuli, daily gains of 7-8% can be increased, and the fattening period can be shortened by 20-30 days.
9, castration early. The earlier the age of castration, the lower the stress on the piglets. The castration was 20-25 days old and was castrated after weaning at 60 days. The daily gain increased by 5-6%, and the slaughter period was shortened by 15-20 days.
10. Prevent epidemic and deworming in due course. It is necessary to strictly follow the epidemic prevention procedures for vaccine injection and drug repellent work for swine fever, swine erysipelas, and swine plague.
Ten Methods for Raising Feeding Rate of Finishing Pigs
1, make full use of the advantages of hybridization. With binary hybrid pigs, the daily gain of purebred pigs can be increased by 15-20%, and the crossbreeding pigs are increased by about 25% than purebred pigs.
