The harm of insufficient milk in sows

When raising pigs, sows need our attention. If the management is not good, sows are prone to a lot of problems. The lack of milk in sows is one of the very common phenomena, for many beginners, the lack of milk in sows does not feel like a big deal. In fact, the lack of mother branch milk is very harmful. So what are the specific ones? The following editor will give you a brief introduction, let's have a look!

1. Increase the mortality of piglets

If there is not enough milk in sows, the first harm is to increase the mortality of piglets. First of all, if the sow does not have enough breast milk, it is very likely to crush the piglets. Especially in the sow in the first week after delivery, because of this period, the sow's body is relatively weak. Due to the lack of breast milk, and piglets frequently arch sows' breasts, resulting in sows upset, constantly lying up and causing piglets to be crushed to death.

And most importantly, if sows don't have enough milk, many piglets will starve to death because they don't have enough to eat. Because the piglets are unable to eat enough, the blood sugar in the body will be reduced, and the body temperature will drop as a result, and eventually die because of body deficiency. And if piglets do not eat enough breast milk after birth, it will increase the incidence of piglets. Because sow milk contains many antibodies, which can effectively enhance the disease resistance of piglets. If there is not enough milk, piglets will be extremely susceptible to disease and, in serious cases, lead to death.

2. Increase the number of remnant pigs

If there is not enough milk for sows after giving birth, the number of authentic pigs will drop sharply after weaning. This leads to a large increase in the number of residual pigs. Because when sows are short of milk, piglets will weigh less when they are weaned. Especially for piglets that have not reached 11 jin in three weeks, this is called a remnant pig. After the beginning of conservation, the mortality and elimination rate of remnant pigs are much higher than those of normal-weight pigs. And the growth speed of the remnant pig is very slow, its breeding risk is also very high, and even the benefit is not as good as the input cost.

3. Increase the fattening cost

At the time of weaning, the weight of piglets is directly related to the final weight. The weaning weight of piglets is mainly provided by sow milk. If the sow does not have enough milk, it will directly lead to the weight loss of piglets when they are weaned. As a result, the feed consumption is excessive, the breeding cost is increased, and the breeding benefit is reduced. This is also the main reason why many pig farms say they can't make money. For example, when piglets are weaned, for every 1 kg of body weight, feed consumption can be reduced by about 6 kg, and the fattening cost of each pig can be reduced by about 15 yuan. Therefore, the higher the weaning weight, the lower the feeding cost.

The above is a brief introduction to the harm of insufficient milk in sows. That's all for today's introduction. This article is for reference only. I hope it can help you all.
