How to prevent the occurrence of stiff pigs by affecting the uniformity and evenness of pigs

In pig farming, there are one or two stiff pigs in each litter, commonly known as "little old pigs". Stiff pigs are shaggy, dull and slow in growth and development, which seriously affects the evenness and evenness of piglets, and then affects the flock rate and benefit of pigs.

First, the causes of stiff pigs:

The main results are as follows: 1. Poor feeding and management of pregnant sows and lack of nutrition hinder fetal development, resulting in congenital deficiency and fetal stiffness.

2. Improper feeding and management of lactating sows, lack of milk or lack of milk in sows, affecting the growth of piglets and causing fetal stiffness.

3. Piglets suffer from repeated or repeated diseases, which affect the normal growth and development of piglets and form "disease stiffness".

4. The piglets start eating late, the feed is poor and the feed quality is poor, which makes the piglets grow slowly and become stiff pigs.

5. Some inbreeding and promiscuous piglets have weak growth ability, poor development and easy to form stiff pigs.

2. Measures to prevent the occurrence of stiff pigs:

1. The feeding and management of sows during pregnancy and lactation should be strengthened to ensure the supply of protein, vitamins, minerals and other nutritional energy, so that piglets can develop well at the embryonic stage. After birth, you can eat enough milk to ensure that piglets grow rapidly and develop well during lactation.

2. Do a good job in piglet rearing and nursing, create suitable temperature conditions, start eating early, feed in time, and ensure the quality of piglet feed to meet the nutritional needs of piglet growth and development.

3. Do a good job in the hygiene and disinfection of piglet pens to make them dry and clean and the air fresh.

4. Timely elimination of parasites in and out of piglets can effectively prevent slow growth and development caused by parasites. Piglets infected with diseases should be detected and treated early, and corresponding effective measures should be taken in time to avoid repeated infection and shorten the course of disease.

5. Avoid inbreeding and sow mismatch to ensure the quality of their offspring.
