How to strengthen the heat prevention and cooling work of raising pigs in summer?

With the coming of summer, with the increase of temperature and humidity, pigs are easy to get sick, so it is necessary to control the ambient temperature in pig houses and strengthen the work of heat prevention and cooling to ensure the safety of pigs through the summer and improve the efficiency of raising pigs. Pig raising in summer should pay attention to the following points:

Build a shed to shade the sun

Most of the pigs raised in rural areas are open pig houses, so a temporary Arbor should be built in front of the house to shade the sun to prevent direct sunlight. Can also build a shed around the house, or plant grapes, pumpkins and other vines, let its vines climb all over the Arbor to shade.

Adjust the diet structure

In the middle of summer, the energy feed in the diet should be relatively reduced, which can increase the green feed. The energy feed is 50%-70% of the diet in peacetime and 40%-50% in summer, and the green feed is increased from 0.5 kg to 1.5 kg. The feed should be fresh and hygienic without mildew.

Feed pigs at night

The feeding time can be carried out at 7 p.m., 11:00 and 4 a.m. three times a night, and 0.5% saline and green succulent feed can be fed at 10:00 and 2 p.m. During the day, as long as the pigs are fed reasonably and meet the needs, the daily gain can also reach 0.5 kg.

Adequate supply of clean drinking water

Water is the best solvent and means of transport for all kinds of nutrients, and the removal of waste in the body is also carried out by water. Pig water accounts for 1 / 3 to 1 / 2 by weight. In summer, the daily drinking water of pigs is 23.8% of their own, and 0.5% of salt water can be drunk to regulate body temperature.

The temperature in the house should be lowered.

Cool water can be used to wash the floor and walls in the ring to cool down. The connecting pipe with tap water condition can be washed several times a day. If there is no tap water, the floor can be washed with water in a basin to reduce the temperature.

Wash pig body with water to cool down

1. Rinse the pig body with spray or shower 2-4 times a day to help dissipate heat.

two。 The water coming out of the well at a low temperature can be basked in the sun for a while before washing the pig body with water, which can not only dissipate heat and cool down, but also make the pig body clean and hygienic.

3. However, when flushing the pig body with water, it should be arranged before feeding and cannot be washed within 30 minutes after feeding, let alone suddenly flush the pig head with water to prevent the strong contraction of blood vessels in the pig head and shock.

Take a bath to cool down

You can dig a shallow pool in a corner of the piggery and pour in clean water so that the pig can soak in the pool at any time to promote the distribution of body heat. If the circle is small and unconditionally dig the pool, you can dig the pool nearby, in the afternoon, release the pig, let the pig freely turn over and soak for 10-20 minutes.

Feed to prevent summer heat

1. Vinegar or sauerkraut juice. It can be taken internally each time, increasing or decreasing according to the size of the pig.

two。 White lentils. White lentils have the effect of relieving summer heat and invigorating the stomach. According to the pig weight, you can use 20-50 grams, fried juice to drink soup.

3. Mung bean soup. Take the right amount of mung beans, add 20 times water and boil until the skin is rotten, cool and drink soup to eat beans.

4. Pan-fry the plants of plantain and light bamboo leaves into soup and mix them with feed to feed the pigs.

5. Watermelon peel. Use 2000 grams of fresh watermelon peel, mash and mix with 100g sugar, once every other day.

Improve the hygiene of pig body and pig house

The pigsty should open all ventilation holes to make the pig body cool and comfortable. the sanitary sand can be laid 3-5cm thick and dissipate heat through the contact between the pig body and the sand. Spray the walls and floor with 20% lime milk every day for disinfection, and disinfect all feedstock with 3% carbonic acid solution.

Safety and epidemic prevention should not only do a good job of immune injection in accordance with the immune procedure, but also do a good job in prevention and treatment of diseases such as sow uterine inflammation, piglet yellow and white dysentery and other diseases in high temperature season.
