The more intake of colostrum, the better the growth and fattening (the lower the cost).

The depressed market has been leading the pig's nerves to test every pig enterprise. However, excessive pig prices will not help the pig farms to tide over the difficulties. Instead, doing what they should do is a wise choice. Concentrating on improving production performance and reducing costs is the only way to get higher profits while waiting for the pig prices to pick up.

1. does intake of colostrums affect piglets' growth and fattening?

The intake of colostrum during the 24 hours after birth affects the performance of the whole growth period. Colostrum is not only a high-energy liquid, but also provides other nutrients and bioactive substances for pigs to stimulate the growth of pigs. Colostrum plays a very important role in helping piglets to survive and their entire life cycle. The Wiegert study assessed how the birth weight of newborn piglets and the intake of colostrum on the day of birth affect the feed intake, daily gain and feed conversion rate of the growth fattening class. Studies have shown that newborn piglets with significant intake of colostrum are best at growth fattening class, but newborn babies are less important. On the contrary, piglets born with high birth weight but small intake of colostrum had a good start, followed by a better conversion rate in the growth class. Therefore, maximizing the intake of colostrum after piglets can improve the performance of growing finishing pigs.

2. how to increase the intake of colostrums in piglets

There are two reasons for the lack of colostrum in piglets: sow is deficient in colostrum and the amount of colostrum in piglets is insufficient. Next, this article will analyze these two reasons to answer how to increase the intake of colostrum.

2.1 how to make sows breast full and increase the production of colostrum?

2.1.1 comfortable environment - feed, water, temperature and oxygen.

(1) to provide adequate feed and clean drinking water to the sows, to provide comprehensive nutrition for the feed, and to use good quality molds and detoxifying agents, such as green Dean, to ensure that sows are not affected by mycotoxins, especially in the 5-10 months of the year. Because mild mycotoxin poisoning can lead to sow breast performance and reduce milk production.

(2) cooling measures should be done in summer to avoid heat stress. Heat stress in summer can not only directly affect the development of sows, but also reduce the intake of sows, thus affecting the ability of lactation. Therefore, pig farms must do the cooling work of piglets.

(3) sows are willing to take good ventilation. The sow house is well ventilated, and the oxygen supply is adequate, so that sows will feel comfortable, and the breast will be full and the milk will be sufficient.

2.1.2 sows secrete enough hormones.

Hormones play a very important role in the development of sows' mammary glands. Enough hormones stimulate breast development and secrete more colostrums. To produce enough hormones, sows need to do the following things: (1) adequate light, 2. Adequate protein content in feed, 3. There is no effect of blue ear virus and circovirus. Sow ear disease can be stabilized by AI new, and Circovirus Disease can be controlled by reasonable immunization procedures.

2.1.3 sows are not affected by postpartum triad (MMA).

Prevention of sow's postpartum triad (MMA), timely detection, timely treatment, and preventive measures. Sulfamethoxazole is an effective broad-spectrum sulfonamide antibiotic. It can effectively prevent mastitis, hystertis and milky free syndrome caused by susceptible bacteria infection in sows, and can prevent the occurrence of MMA in sows. Besides, sows should be injected with antibiotics in time to prevent the occurrence of MMA.

2.1.4 probiotics - promote breast development, enhance lactation and intestinal mucosal immunity (MI, Mucosal immunity)

Probiotics can promote the intestinal health and enhance the function of intestinal mucosal immunity (MI) by promoting the characteristics of natural microbial flora, improving intestinal health and enhancing intestinal mucosal immunity (MI), enhancing sow absorption capacity, breast fullness, enhancing lactation ability, and increasing the content of IgA (anti body) in colostrum, improving the quality of colostrum.

2.2 how to help piglets eat colostrums

The study found that there were two main reasons for insufficient intake of colostrum in piglets during the production of adequate sows. First, sow production was too long; two, the weak piglets born later were unable to compete for nipples, and could not eat colostrum or less colostrum. To help piglets eat good colostrum, we should first shorten the labor process of the sow, control the time within 3-4 hours, the piglets will output as soon as possible, have the opportunity to get more colostrums, and at the same time collect the colostrums artificially to feed the piglets, so that all piglets will get enough colostrum, especially the weak piglets.

2.2.1 shortening sow labor

(1) sows will be able to catch up with the output of about 5 heads, allowing them to move and help the piglets move to the birth canal smoothly. The reason is that the uterus of the sow belongs to the double horn uterus, which is easy to form folds in the abdominal cavity. It is difficult to produce the fetal pig in the fold placenta (Fig. 1).

(2) intravenous drip. Because sows consume a lot of calcium ions (uterine smooth muscle contraction coupling agents) and abilities, intravenous drip of calcium ions and energy is very important for shortening the process of sow labor, especially in the hot summer months. Specific methods: first, the preparation of a good infusion solution (formula: 20% boron calcium gluconate 60ml+ compound cloth phosphorus phosphorus injection 15ml+ vitamin B complex 7ml, mixed in 5% dextran glucose salt solution, 1000ml); when sows produce 5-7 piglets, began to drip.

2.2.2 colostrum management

(1) colostrum collection

Before colostrum collection, clean sows with clean disinfectant (such as diluent or hydrogen peroxide water diluent) and hot towels. When sows were born 5-7 times, the sows were artificially squeezed and colostrums were collected with bottles (Figure 2).

(2) colostrum colostrum

The colostrum can be artificially fed to piglets immediately (Fig. 3). Each time the amount of piglets feeding was determined by whether the piglets were struggling, when the piglets struggled, they said they had enough to eat. To ensure that each piglet is administered at least 3 times (one mark per piglet), each time interval is about 1 hours (gastric emptying), and piglets feed 1 or 2 times per time, reaching a total of 4-5 times.

(3) the main points of colostrum administration

Colostrum dressing must be carried out within 6 hours after the birth of the piglets, because the Fc associated with the maternal antibody (IgA) in the intestinal mucosa of the piglets was replaced after 6 hours (Fig. 4), when the maternal antibody could not bind to the receptors on the intestinal mucosa, it could only be digested and absorbed by the intestinal tract just like ordinary protein. Therefore, colostrum is very important for piglets to be born within 6 hours after birth.

Colostrum is usually used immediately. It can be refrigerated for several hours. It can also be stored at -20 C for a long time. When it is used, it is thawed at 37. When the amount of colostrum in a sow is large, it can be fed to other piglets with poor colostrum. The gilts are kept in the farm for a long time, and the pathogen has long been exposed to the farm for a long time. There are many kinds of antibodies in the colostrum. Therefore, it is possible to select the sows produced by the sows of the multiparous sows to feed the sows with poor colostrum. In addition, the pathogen of the same pig house is similar to that of the sows. Therefore, the colostrum produced by the same sow is better for feeding the same piglets.
