The ambient temperature in summer is suitable for the mass reproduction of bacteria and other pathogens and the spread of arboviruses, and the appetite of pigs will be greatly reduced, resulting in no weight gain or even fat loss.

How can pigs grow faster in summer?

1. It is very important to build a pigsty, ventilate and shade the sun. The sun is hot in summer, we always say that the sun is hot, in the hot environment, it is easy to lead to loss of appetite of pigs. Therefore, there is a ventilated sunshade shed, so that pigs stay in a relatively cool environment, then pigs will eat more smoothly. Pig houses must be well ventilated, and conditional pig farms can install fans and cooling equipment to provide pigs with a suitable growth environment as far as possible.

two。 The choice of feed is very important, feed more fresh green material. Green feed, such as alfalfa and sweet potato seedlings, is not only palatable, but also has the effect of clearing heat and relieving summer heat, which can effectively promote the appetite of pigs; in addition, green feed is rich in nutrients, especially vitamins, which can provide adequate nutrition for pigs.

Good feed determines the enthusiasm of pigs to eat, if you are not interested in eating, why can you expect pigs? Pigs do not like to eat, then, the growth of the pig itself is blocked, and even the phenomenon of losing weight appears.

The selection of feed should pay attention to quality, and the appetite of pigs in summer is decreased, which can appropriately increase the content of protein in feed to provide nutrients for pig growth. When necessary, certain additives and some taste enhancers can be added to promote the appetite of pigs, so as to achieve a better feeding purpose.

3. The time for feeding pigs needs to be adjusted. The time for feeding pigs can be placed in the relatively cool time in the morning and evening to avoid the hot noon period. Especially in the heat season, you can choose to feed at night. 19:00 to 23:00 at night, four or five o'clock in the morning, these periods, the temperature is lower, at this time feeding pigs, the appetite of pigs will increase.

4. Keep adequate drinking water to avoid heatstroke in pigs. In hot weather, pigs mainly rely on a lot of drinking water to cool down. Therefore, in summer, pigs must be provided with sufficient clean and cool drinking water, and it is best to install automatic drinking fountains in pig sheds.

5. Do a good job in epidemic prevention, reduce the incidence of diseases, and do a good job in summer disease prevention. With the advent of summer, mosquitoes and flies are also gradually increasing. At this time, it is all the more necessary to keep pig pens and pig houses clean and do a good job of deworming.

How to prevent and cure pig heatstroke in summer?

1. Build a shed to shade the sun

Most of the pigs raised in rural areas are open pig houses, in which the temperature control ability is poor. Before the high temperature comes, you can lay a thick layer of rice straw, wheat straw and other thermal insulation on the top of the pigsty; build an Arbor above the open space of the enclosure; plant vines (towel gourd, gourd, grape, etc.) next to the enclosure, which can not only shade the sun, but also purify the air of the enclosure, provide melons and vegetables, and plant broad-leaved trees around the pigsty to improve the microclimate around the enclosure. Painting a layer of fresh lime milk inside and outside the walls of the pig house, using the effect of white reflection to reduce the amount of sunlight on the pig house, and has a good disinfection effect.

two。 Adjust the diet

The proportion of energy feed in the diet should be reduced and the protein level should be increased accordingly; more green feed rich in vitamins and minerals and cool feed such as watermelon peel should be fed; seasoning such as salty, fresh or fragrant flavor should be added to the mixture to improve the palatability of the feed and increase the feed intake of pigs; the feed should be fresh and should not be fed with moldy and deteriorated feed. Reference formula: pigs under 35kg, 39% corn, 22% wheat, 15% wheat bran, 7% rice bran, 7% soybeans, 6% vermicelli, 2% bone meal, 1% salt, 1% auxin. 35 kg ~ 60 kg pigs, 37% corn, 24% wheat, 19% wheat bran, 11% rice bran, 5.5% fish meal, 1.5% bone meal, 1% salt, 1% auxin.

3. Adjust the feeding time

Pigs should be fed to avoid the hottest time at noon. Four times a day, once at 4 am, 10:00, 4 pm and 9 pm respectively. This reduces the activity of pigs during the hottest period. Give pigs 0.5% light salt water once a day, provide sufficient green and succulent feed, and keep plenty of cool drinking water in the trough.

4. Cooling in the enclosure

Open all the ventilation holes in the piggery, remove the feces and urine in time, and spray and rinse the enclosure with cold water to minimize the dirty gas in the enclosure, reduce the biothermal effect of feces, and create a cool and comfortable growing environment for pigs. Be careful not to splash the pig with cold water to prevent diseases. Conditional pig farms can install ventilation fans or electric fans on the walls of the houses to accelerate air circulation and achieve cooling effect.

V. Preventive use of drugs for preventing heat

Appropriate amount of heat-clearing and thirst-relieving drugs can be added to feed or drinking water. Plantain 100g, water fried juice mix feed; mung beans boiled into gruel, wait for cool, feed; white lentil 20g ~ 25g, water fried juice feeding; fresh watermelon peel 2000 grams, mashed plus 100g sugar, stir evenly; vinegar or sauerkraut juice 250ml ~ 500ml, mixed into the feed, all have a good preventive effect.

What are common pig diseases in summer?

There are many kinds of pig diseases, including infectious diseases, parasitic diseases, internal diseases, surgical diseases and obstetrical diseases, etc., and infectious diseases are the most serious, followed by parasitic diseases, toxic diseases and nutritional deficiencies (including metabolic disorders). If these diseases are not well prevented, they will cause inestimable losses to pig farms.
