How to make piglets eat enough colostrum and fix nipples?

1. Eating enough colostrum colostrum refers to the mixture of secretions accumulated by sow mammary glands in the late pregnancy and protein whose blood is transferred by estrogen and progesterone. High initial lactic acid is beneficial to digestive tract activities and can promote meconium discharge. Colostrum usually refers to the milk secreted by sows within 3 ~ 5 days after delivery, especially within 3 days. Albumin is the most important source of disease resistance in early piglets from colostrum, which contains magnesium salt and has laxative effect. Due to the special physiological characteristics of suckling piglets, it is difficult to raise piglets and the survival rate is low. If newborn piglets can't eat colostrum, it is difficult to feed them, because eating enough colostrum as soon as possible is the only way to gain immunity. Colostrum not only contains enough immune antibodies, but also contains various nutrients and bioactive substances needed by piglets. Lactose and fat in colostrum are the main sources of exogenous energy for piglets, which can improve the cold resistance of piglets. Colostrum plays a positive role in promoting metabolism and maintaining blood sugar level; Piglets can eat colostrum beside sows at any time after birth, which can stimulate the activity of digestive organs, promote the discharge of meconium, increase nutrition and heat production, and improve the resistance of piglets to cold. Therefore, after the pig is born, you must ensure that you eat enough colostrum. When piglets are born, they are weak in limbs and inconvenient to move, especially the weak piglets, who often can't find nipples in time, especially in the cold season, piglets may be frozen and lose their ability to breastfeed. Therefore, piglets are required to be dry after birth, put into an incubator immediately after the umbilical cord is broken, and all piglets are assisted in breastfeeding immediately after birth. It can also be fed with it, so that piglets can eat colostrum as soon as possible and get nutrition as soon as possible. After the sow gives birth, all the piglets can eat enough colostrum. If sows have no milk, piglets should be assisted to eat the colostrum of foster sows as soon as possible.

2. Piglets with fixed nipples have the habit of sucking milk with fixed nipples. Which nipple is sucked several times at first, once it is determined, it will remain the same until weaning. However, newborn piglets often fight for nipples when they start to nurse. Strong piglets scramble to occupy the nipples in front, weak piglets can't find nipples, miss milking time, and eat little or no milk at all. It is also possible that the sow lies on her side, and the lower nipple is buried under her abdomen, which causes the piglets to compete for the upper nipple and bite the sow nipple, which leads to the sow's refusal to breastfeed. In order to make piglets in the same litter develop in a balanced and healthy way, it is necessary to adopt artificial assistance methods within 2 ~ 3 days after birth to urge piglets to form the habit of sucking a nipple as soon as possible.

(1) nipple fixing principle: weak piglets should be fixed to the front nipple, and healthy piglets with large newborn weight should be fixed to the back nipple. In this way, we can make use of the law that different nipples of sows produce different milk, so that weak piglets can get more milk to make up for their congenital deficiency. Although the milk output of the rear nipple is insufficient, the intense action of rubbing and sucking the breast can still make up for the shortage of milk output of the rear nipple, so as to achieve the goal of rapid and uniform growth and development of piglets in the nest.

(2) Method of fixing nipples When there is little difference between piglets in the same litter and there are enough effective nipples, most of them can fix their nipples within 2-3 days after birth without interference. But if the competition between individuals is fierce, it should be managed. If there is a big difference between piglets in the nest, we should focus on controlling the piglets with large size and small size, and the piglets with medium size can choose freely. Every time, the small individual is assisted to suck milk at the front nipple, and the large individual is fixed at the back nipple. Individuals struggling for severe disorder arch need to be controlled manually. They can not arch their breasts first, just put their breasts in a fixed position at the moment before milk release, or simply stop sucking once or twice to correct their milk grabbing behavior. After two days, the whole litter of piglets can basically fix their nipples when breastfeeding.

(3) Using the auxiliary method to accelerate nipple fixation (1) Labeling piglets according to the nursing order, and marking different parts of piglets with dyes that are not easy to fade (such as purple medicine) in production, so as to quickly fix the nursing position. If the breastfeeding position can be kept unchanged for 5 ~ 10 times, it can be fixed on the first day after delivery. ② Training sows to lie on their side is helpful for piglets to identify nipple position as soon as possible. Before the nipple is fixed, the sow can lie on her side, first fix the pig that sucks the nipple, and then fix the pig that sucks the nipple. ③ Fix nipple with "partition". Put a board in the middle of the sow to separate the piglets, so that the number and range of activities of the piglets are relatively reduced, and prevent them from scurrying back and forth because they are looking for nipple positions during breastfeeding.

(4) Signs of fixing nipples Piglets can be fixed on a nipple to arch and rub their breasts when sows are breastfeeding, and there is no phenomenon of bullying, bullying and fighting for nipples. When the sow milks, the piglets all suck milk quietly. Fixing nipples is a meticulous work, which should be done seriously. The speed of nipple fixation is often one of the signs to measure a breeder's sense of responsibility and operational skills.
