Strengthen the feeding and management of newborn piglets to improve the breeding benefit of piglets

Piglet production is an important link in the pig industry, and positive and effective measures are an important way to improve the economic benefits of pig farming. The mortality rate of newborn piglets is high, which will bring great economic losses to pig production. Therefore, careful feeding and management of newborn piglets is the main measure to improve piglet production. In production practice, we should pay attention to the following key points:

Piglets

1. Eat enough colostrum

Since newborn piglets have no innate immunity, antibodies can only be obtained by sucking colostrum. The digestive function of piglets is weak, the stomach digestive juice is lack of hydrochloric acid, and the nutrition of colostrum is extremely rich, which contains a lot of protein, milk fat and high acidity, which is beneficial to promote the activity of digestive tract of piglets and meet the needs of growth and development of piglets. If weak piglets are not sucked enough, artificial supplementary feeding can be carried out to improve the survival rate of the whole litter of piglets. Therefore, after the birth of piglets, piglets should be able to eat and eat enough colostrum as soon as possible.

2. Ensure the ambient temperature

The best environmental temperature for newborn piglets is 32 degrees, and the suitable temperature within one week is 25-30 degrees, so an incubator is installed on the birth bed, with an insulation lamp inside and a thermal insulation pad below. Those who can not meet the conditions can establish a simple greenhouse according to the actual situation. If it is in winter, the construction materials of the greenhouse can be made locally. It is generally required to be 1.2 meters long, 0.75 meters wide and about 1 meter high, and leave a small door at the bottom of one side of the greenhouse for piglet colostrum. Try to make sows and piglets sleep separately to prevent sows from crushing piglets.

3. Supplement trace elements

Iron is an important component of heme. Newborn piglets have very little iron in reserve, with a daily requirement of 7mg to 8mg, and the amount that can be obtained from breast milk is also limited, so if the piglets are not given iron in time, it will lead to anaemia in piglets.

4. Foster care and nesting

Foster care means that when sows die or have no milk after birth, or when the number of piglets born exceeds the number of effective nipples, those piglets without milk are called to be fed by other sows. Combined litter means that sows give birth to less piglets or some piglets die for some reasons. in order to improve the utilization rate of sows, these piglets can be raised together, and before nesting, piglets must be given enough colostrum.

Before boarding and raising, wipe the whole body of piglets with the milk of foster sows (not recommended to use sow urine), and choose to mix at night, so that the sows can not distinguish between self-produced and foster piglets. After that, pay attention to observation to prevent sows from refusing to breast-feed or bite piglets. The delivery period of piglets raised in foster care is similar to that of piglets in the same litter, and it is best not to exceed 3-4 days.

5. Disease prevention

Before eating colostrum, the piglets can be vaccinated with attenuated vaccine of classical swine fever according to the routine dose, and the piglets can be fed freely after 2 hours. In addition, antibiotics can be injected into sow feed to prevent postpartum infection in sows and red and yellow dysentery in piglets. Clean the enclosure every day to keep it clean and dry so as to provide piglets with a clean, quiet and fresh living environment. Observe carefully every day and treat piglets in time when they are sick.
