The rate of fattening determines the benefit of raising pigs and how to improve the rate of fattening pigs.

Piglets

1. Make use of heterosis. The daily gain of binary hybrid piglets is 15-20% higher than that of purebred pigs, and the daily gain of ternary hybrid pigs is about 25% higher than that of purebred pigs.

2. Replenish iron early. After birth, piglets need to eat 7 milligrams of iron a day, while they can only get 1 milligram from breast milk. Such as piglets intramuscular injection of ferritin 1 ml, the effect is better.

3. Increase the birth weight and weaning weight of piglets. The heavier the piglets are at birth, the better they are to feed, gain weight quickly, and weaning is significant. According to the experiment, under the same feeding conditions, the fattening pigs with large weaning body weight are 1-2 months shorter than those with low weaning weight.

4. Provide suitable temperature and humidity. The temperature and humidity of the pig house are too high, resulting in less feed intake and a decrease in daily gain. If the temperature is too low, the heat energy consumption is high, the food intake is large, and the feed reward is low. Pigsty temperature, piglet 20-30 ℃, adult pig 15-20 ℃, humidity 50-55%.

5. Provide adequate clean drinking water. Adequate drinking water ensures that fattening pigs have strong metabolic capacity.

6. "four determinations and one change" feeding method. That is, determine the feeding times, the feeding time, the feeding amount, the feeding standard, and change the wet mixture into dry powder. 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. Feed quantity should be balanced each time.

7. Reasonable feeding density. Each pig occupies 0.8-1 square meters. Piglets aged from 3 to 4 months old accounted for 0.6 square meters each, 4-6 months old accounted for 0.8 square meters, and 7-8 months old accounted for 1 square meter. Each pig occupies 1.1-1.2 square meters in summer and 0.9-1 square meters in winter.

Fattening pig

8. Feeding in the same nest and in the original circle. From birth to fattening, the effect of feeding in the same litter in the same litter was better than that in the mixed culture after weaning. Due to the reduction of stress, daily weight gain can be increased by 7-8%, and the fattening period can be shortened by 20-30 days.

9. Early castration. The earlier the castration age, the less the stress effect of piglets. 20-25-day-old castrated compared with 60-day-old after weaning, daily gain increased by 5-6%, and the column period was shortened by 15-20 days.

10. Timely epidemic prevention and deworming. In strict accordance with epidemic prevention procedures, piglets should be vaccinated against swine fever, swine erysipelas, swine lung disease and other diseases and dewormed by drugs.
