When did the piglet break its tail, and the reason why it was broken after parturition?

The time for piglets to break their tails: within 1-2 days after birth, the tail is cut off 2.5 cm from the root of the tail. The reason for the broken tail of piglets: it can save feed, increase daily weight, reduce tail biting, improve carcass quality, effectively reduce piglet mortality and be beneficial to pig health. The method of breaking the tail of a pig: cut it off with scissors, or burn the tail of the pig, and cut it off slowly with an elastic rope.

First, the time when the piglet broke its tail.

Piglets generally cut their tails within 1-2 days after birth, during which the tail is cut off from the tail root 2.5cm. The recovery period of piglets is relatively fast, only 10-15 days. Before preparing for tail amputation, you need to prepare tools after high temperature disinfection, mainly cotton, alcohol, purple potion, scalpels, one-sided blades and so on.

Second, the cause of the broken tail of the piglet

1. Save feed and increase daily weight

Because the energy consumed by swinging the tail every day accounts for 15% of the daily metabolic energy, it virtually causes a waste of feed. If this part of the energy is used for fat deposition, the weight can be increased by 2%, 3%, and the feed can be saved. At the same time, it can also reduce the anxiety of pigs caused by swinging tail, which is conducive to sleep.

2. Reduce tail biting

The main results are as follows: (1) tail biting is a vice of pigs, and the reason is very complicated. if the piglets are cut off during the period, the occurrence of the disease can be effectively controlled.

(2) according to relevant statistics, tail biting disease can reach 200% in the same group, because the emergence of tail biting disease will reduce the diet and disease resistance of pigs, and is easy to be infected with necrotizing bacilli, staphylococci, streptococci, etc., while reducing the production performance of pigs, and cutting off the tail of piglets greatly reduces the occurrence of tail biting disease.

3. Improve carcass quality.

After the severing of the tail, the intercostal fat deposition of the pig increased, at the same time, the muscle fiber became delicate, the masticatory resistance rate decreased, the palatability was enhanced, and the slaughtering rate could be increased by 4% and 5%.

4. Reduce the mortality of piglets.

The survival rate of piglets can be significantly improved after severing their tails, mainly because suckling sows may inadvertently press the tail of piglets, making them unable to move, and piglets cannot compete, so it is easy to cause death, and some sows are addicted to eating piglets' tails, which can be avoided after cutting off the piglets' tails.

5. it is beneficial to the health of pigs.

It is not easy to expose the anus, and the feces and urine will not stick to the tail, and diarrhea will not throw the feces around because of the swinging of the pigtail, which is conducive to the hygiene of the pigs.

Third, the method of cutting off the tail of piglets.

1. Cut with scissors

Using scissors to cut off the tail is a traditional old method. First disinfect the scissors and the piglet's tail, and then prepare sharp scissors, which can effectively reduce the pain of the piglet. After cutting the piglet's tail, disinfect and bandage it immediately to avoid bacterial infection.

2. Burn off the pig's tail

Use the method of burning the tail to cut off the tail of the pig, it is not easy to be infected by bacteria, but the disadvantage is that the pig is easy to be scalded, during which the soldering iron must be heated well, so that it is fast and accurate. The advantage of this method is that the broken tail is difficult to grow again.

3. Slowly break it with an elastic rope

Using elastic rope to cut off slowly is a chronic method, which takes a long time, and its advantage is that there is no pain. During this period, the elastic rope is tied to the tail, which can make the piglet's tail fall off naturally due to long-term lack of nutrition.
