What nutrition should be paid attention to in raising piglets in spring and summer?
The temperature rises gradually from March to June, which is a favorable period for the development of production. Four problems should be paid attention to in breeding.
First, pay attention to the change of temperature. The temperature changes greatly in spring and summer, Rain Water is more, the temperature is larger. Pigs like dry environment, how much fat tissue, piglets are easy to be afraid of cold. Therefore, the temperature in the house and the dry environment of the house should be maintained.
Second, pay attention to the increase of protein feed. Especially for piglets after long-distance transportation, due to the stimulation of wind chill and bumps of cars and boats, some piglets have diarrhea and diarrhea, loss of appetite and weight loss. in addition to doing a good job of drying and keeping warm in the barn, they should also supplement nutrition in time and feed full-price formula feed to promote the rapid growth of piglets.
Third, pay attention to feeding green feed. Green feed not only has the characteristics of easy to breed, easy to collect, high yield and good palatability, but also has high protein content, it is also rich in Vividin and minerals, so it has a good feeding effect on piglets.
Fourth, pay attention to timely deworming. During the period from piglet to shelf pig, the worm should be deworded 2-3 times a month.

Prevention of Japanese Encephalitis in Pigs in early Summer
In early summer, the climate gradually becomes hot, and all kinds of mosquitoes (such as Culex pipiens, Aedes albopictus, Anopheles mosquitoes, etc.) begin to multiply in large numbers. Mosquitoes are important vectors for the transmission of Japanese encephalitis virus. After feeding on the blood of sick animals, mosquitoes can carry the virus for life and can carry the virus through the winter, becoming the source of infection in the following year. Japanese encephalitis can infect many kinds of animals and people, and do the most serious harm to pigs, especially it can destroy the reproductive performance of pigs, lead to miscarriage of pregnant sows, give birth to stillbirths, weak fetuses, mummified fetuses, and orchitis in boars.

High temperature causes heat stress and affects the physique of pigs.
The high temperature environment from June to September every year disrupts the secretion of sex hormones in pigs, disrupts the normal mechanism of oestrus, and makes the symptoms of estrus not obvious or non-estrous; high temperature makes pigs focus their energy on resisting high temperature stress, and accordingly weakens the functions of other aspects. this will lead to lack of milk and slow growth due to lack of nutrition for lactating sows and fat pigs that need to eat a lot. High temperature will make it difficult for boar testis to dissipate heat, intensify sperm metabolism and shorten life span, thus reducing sperm motility and even death; high temperature will also make newly fertilized sperm fertilized.
