Causes of slow Fat gain in raising Pigs in Winter

Pork as a meat product with the largest annual consumption in our country, the demand is relatively large in our country all the year round. And some pig farmers will find that the rate of pig fat gain is very slow when raising pigs in winter. As a result, the cost of raising pigs will increase, and the time of raising pigs will be delayed, thus leading to a decline in the efficiency of raising pigs. So what is the reason why pigs gain weight slowly in winter? The following editor will give you a brief introduction, let's have a look!

1. Improper weaning

When raising pigs, many pig farmers will mainly use one-time weaning method when weaning their piglets. Piglets appear on the market immediately after weaning, and there are many disadvantages of one-time weaning. Because the piglets used to live in a stable and comfortable environment centered on sows. Sudden weaning leads to a sudden change in the growth environment of piglets, resulting in the inability of piglets to adapt in time, thus affecting the fat gain of piglets. Therefore, in the week before weaning, the number of times of sucking breast milk should be appropriate, step by step, until completely weaned, weaning stress can be effectively avoided.

2. The replenishment is not timely.

During the lactation stage of piglets, farmers should do a good job of feeding. If there is no timely feeding during lactation, the piglets will not be able to eat feed normally after weaning. This hinders the growth of piglets and leads to poor growth and development of piglets. Therefore, we still need to do a good job of feeding, and we have to start feeding when the piglets grow to a week. So that the sows can eat feed normally when the milk yield decreases, and ensure the normal growth and development of piglets. At the beginning of feeding, it is necessary to give priority to sweet and digestible feed, and gradually transition to normal pig feed.

3. Improper management

Nowadays, when raising pigs, many farmers raise pigs in the form of a circle of pigs. On the other hand, pigs eat, drink or rest and defecate in one place. Coupled with the failure of farmers to clean the pigsty in time, the growth environment of pigs is very poor. Especially when the temperature is low in winter, pigs are very prone to various diseases and have a great impact on the growth of pigs. Therefore, we have to control the size and eating speed of pigs in a circle of five, so that pigs can grab food from each other, so as to improve the food intake and growth rate of pigs. Then we should do a good job in cleaning the pigsty to ensure the environment of the pigsty.

4. Improper castration of epidemic prevention

When many farmers buy pigs, the epidemic prevention and castration of pigs will be carried out together. As a result, piglets are subjected to three kinds of stress of epidemic prevention, castration and weaning at the same time, which seriously affect the growth of piglets, lead to piglets unable to regain their weight for a long time, and in serious cases, lead to the formation of stiff pigs. Therefore, we should control the castration time according to the different uses of piglets, for example, if they are non-breeding piglets. So boars do it in 3 weeks and sows in January. It is necessary to do a good job of epidemic prevention before feeding after birth and the second epidemic prevention after weaning to avoid diseases such as classical swine fever erysipelas.

The above is a brief introduction to the reasons for the slow weight gain of raising pigs in winter. That's all for today's introduction. This article is for reference only. I hope it can help you all.
