High-efficiency breeding technology for pigs in pig farms
With the development of China's aquaculture industry, the breeding technology of the pig industry has become more and more scientific. The breeding efficiency of pigs is the main link that determines the cost of raising pigs. Let's take a look at the efficient breeding techniques of pigs in pig farms.
1. Do a good job in postpartum rehabilitation
Oxytocin is injected during the delivery of the sow. When the sow produces 2 to 3 piglets, 40 to 50 international units of oxytocin can be injected. After the complete delivery, the same dose of oxytocin is injected once. In combination with long-acting antibiotic injection, the uterine fetal clothes and lochia are exhausted. The next day, intramuscular injection of sodium chloroprostol 0.1~0.2 mg can reduce the stress of the sow, effectively promote the recovery of uterus and ovary function, and increase the secretion of milk. To avoid the occurrence of symptoms such as endometritis and incomplete dew, significantly shortening the sow empty period and increasing the number of lower fetuses.
2. Inducing sow estrus
Some sows do not estrus for a long time after weaning, which wastes time and increases costs. In the 24 hours after the weaning, the somatic serum of the pregnant horse is 1000 international units, and the sow is induced to estrus. Generally, the estrus rate of the sow can reach more than 90% in 3 to 5 days, thereby achieving the purpose of increasing the annual litter size of the sow.
3. Improve the conception rate and birth rate of sows
When the sow is in estrus, the number of mature follicles on the ovary is much more than the number of calves produced. This difference mainly has three physiological links:
1 sows are not ovulating.
2 Delayed ovulation causes unfertilized.
3 implantation difficulties lead to early embryo death. Promote the secretion of follicle stimulating hormone and lutein by the pituitary gland, thereby promoting the full maturation of follicular eggs and increasing ovulation; concentrating the ovulation process, allowing the eggs to be fertilized in time; enhancing the vitality of the fallopian tubes and uterus, making fertilization and implantation easier. . One hour before the sow breeding, the intramuscular injection of ovulation on the 3rd 25 micrograms can achieve the purpose of increasing the conception rate and the number of calves.
4. Sow delivery control
It turns out that most sows give birth at night, which can lead to difficulty in working arrangements, increased mortality and increased mortality in newborn piglets. 1 to 2 days before the expected sow of the pregnant sow, according to the seasonal and local temperature, select the appropriate time for intramuscular injection of 0.2 mg of sodium cloprosate or 0.1 mg of the inside of the labia. The drug effect time is 22 to 23 hours, so that the sow can be used. In the ideal time of childbirth, the effective rate can reach more than 80%, which can reduce the difficulty of the breeder and reduce the piglet mortality, and can also reduce the dystocia of the sow.
