Problems solved by technology

At present, the problems faced by domestic pig farms: 1. High litter size, many stillbirths and mummies, and small number of live pigs; 2. High number of live pigs and high postpartum mortality; 3. The survival rate of suckling piglets is high, but the nursery piglets The mortality rate is also high, resulting in a low number of fattened sows in the year

Embodiment Construction

[0009] (1) Sow pregnancy technology

[0010] Only by strengthening the feeding and management of sow pregnancy can we obtain piglets with large newborns, large numbers, and strong physiques, laying the foundation for piglet breeding.

[0011] 1. About 20 days after pregnancy (10-30 days) is the first critical period. When the fertilized egg is attached to the uterus to form the placenta, if the embryo is not firmly bonded to the placenta, it is easy to abort and die.

[0012] 1) In terms of nutrition, attention should be paid to the complete price of the feed and the nutritional quality of the feed. Never feed moldy, toxic, or frozen feed, otherwise it will easily cause early embryonic death and abortion.

[0013] 2) After sows are mated, put 1 fetus into the vagina to adjust the uterine environment and nutrition, relax the uterine smooth muscle, promote the implantation of the zygote, and improve the number and quality of embryos.

[0014] 2. The last month of sow pregnancy. At this t...

Abstract

The invention provides a technology for improving the survival rate and promoting quick growth of piglets and is applied to the technical field of pig breeding. According to the technical scheme provided by the invention, embryonic development of sows is good, dead fetuses are a few, birth weight is regular, number born alive is large, sow dystocia incident rate is low and milk of lactating sows is good; the survival rate of suckling piglets is high, and the growth rate is high; the weaning stress of the suckling piglets is small, the attack rate of weaned pigs is low and the growth of the weaned pigs is good. The technology is characterized by comprising a sow gestation technology, a piglet birth technology, a feeding and management technology, a weaning survival technology and a disease control technology. The invention provides the technical scheme systematically on piglet feeding, so that piglet breeding is routinized, digitalized and systematized, the production potential of the sows is fully exerted really, the effects of improving the survival rate and promoting quick growth of the newborn piglets are achieved, the sow feeding cost is reduced, the survival rate of the piglets is improved and the economic benefit of pig breeding is increased.

Description

Technical field [0001] Pig breeding technology. Background technique [0002] Raising piglets well is the foundation for pig production. If piglets are raised well, the number of pigs alive will increase, and the average sow productivity will be higher. This directly reflects the level of pig production and plays a role in improving the economic efficiency of pig raising. Very important role. The current domestic pig farms are facing problems: 1. High litter size, more stillbirths, mummies, and low number of live piglets; 2. High number of live litters, high postpartum mortality; 3. High survival rate of suckling piglets, but piglet care The mortality rate is also high, resulting in the low number of fat pigs in the year. In order to solve the number of piglets weaned by sows and improve the survival rate of nursery pigs, after more than 20 years of clinical practice, I invented this technology. [0003] The difference between this technology and previous technical solutions lie...
