CATDOLL : CATDOLL: Pig pregnancy and delivery process explained in detail: the whole process from conception to birth

Detailed explanation of the pregnancy and delivery process of pigs

Pigs are one of the most important farmed animals. Understanding the pregnancy and delivery process of pigs is not only helpful for farming management, but also helps to improve the reproductive efficiency of pigs. This article will introduce the pregnancy and delivery process of pigs in detail, including pig conception, pregnancy cycle, prenatal preparation, delivery process, etc., hoping to provide reference and guidance for pig farmers.

1. Pig conception process

Conception in pigs refers to the combination of the pig's fertilized egg and sperm to form a fertilized embryo. Generally speaking, sows will accept mating from boars during estrus, and the fertilized egg will develop into a fertilized embryo in the fallopian tube. The estrus cycle of sows is about 21 days, but the highest conception rate is 2-3 days after estrus. Therefore, in order to increase the conception rate, pig farmers can breed in time during the estrus period.

2. Pig pregnancy cycle

The gestation period of a pig is about 114 days, but it can vary depending on the breed. During pregnancy, pig farmers need to provide the sow with a suitable feeding environment and feed to ensure the healthy development of the fetus. In addition, pig farmers also need to conduct regular prenatal examinations on the sow to ensure the physical condition of the sow and the fetus are in good condition.

3. Prenatal preparation of pigs

Before the pigs are about to give birth, pig farmers need to prepare the sows for delivery. First, they need to prepare a clean, quiet and comfortable delivery environment for the sows, which can be a delivery cage or a delivery box. Secondly, pig farmers need to prepare delivery tools, cleaning and disinfection tools, etc. in case of emergency. In addition, they also need to ensure the feeding and nutrition of the sows, to ensure that the sows are healthy and have enough energy and nutrition to supply the growth and development of the fetuses.

4. The process of pig farrowing

The pig's birthing process can be divided into three stages: weaning, delivery, and hindmilk. In the weaning stage, the sow's breasts will swell and the milk secretion will increase. In the delivery stage, the sow will have obvious pre-delivery movements, such as faster nasal breathing and paying attention to self-sanitation, and finally the fetus will be smoothly delivered from the sow's reproductive tract. In the hindmilk stage, the sow will breastfeed and care for the newborn fetus to promote the growth and development of the fetus.

Summarize

Through the introduction of this article, we have learned in detail about the pregnancy and delivery process of pigs. Understanding the conception, pregnancy cycle, prenatal preparation and delivery process of pigs is not only important knowledge for pig farmers, but also helps to improve the reproductive efficiency of pigs. Of course, in actual operation, adjustments and improvements need to be made according to specific circumstances. I hope this article can provide some help and reference for pig farmers.
