What should I pay attention to when raising pigs in summer?

It's very hot in summer. In order to resist heat, pigs tend to lose weight, grow slowly and even die of heatstroke. Therefore, it is necessary to strengthen heatstroke prevention and cooling in midsummer to ensure the safety of pigs in summer and improve the economic benefits of pigs. Now I'd like to introduce eight heatstroke prevention and cooling measures to you.

First, shading, washing and cooling. Most pig houses in rural areas are open, so it is necessary to set up a temporary shed in front of the house to shade them from direct sunlight. You can also build a shed around the house, or plant vines such as grapes and pumpkins, and let their vines cover the gazebo for shade. You can also use cold water to wash the ground walls in the circle to cool down. If there is running water, wash the water pipes several times a day. If there is no running water, fill the pool with a basin to reduce the indoor temperature.

Second, adjust the diet structure. In midsummer, the energy feed in the diet should be relatively reduced, and the green feed can be increased. Energy feed is 50%-70% of the daily diet at ordinary times and 40%-50% in summer; Turquoise feed was increased from 0.5- 1 kg to 1- 1.5 kg. Feed should be fresh, hygienic and free from mildew.

Third, feed the pigs at night. Feeding time can be at 7: 00 p.m., 165438+ 0: 00 a.m. and 4: 00 a.m. three times a night, and 0.5% saline solution and green juicy feed can be fed at 10 and 3: 00 p.m. during the day. As long as the feeding is reasonable and meets the needs, the daily weight gain of about 50 kg pigs can reach 0.5-0.75 kg.

Fourth, supply sufficient clean drinking water. Water is the best solvent and means of transportation for various nutrients, and the removal of wastes in the body is also operated by water. Water in pigs accounts for one-third to one-half of their body weight. In summer, pigs drink 23.8% of their daily water, so they can drink 0.5% salt water to regulate their body temperature.

5. Wash the pig with water and let it cool.

(1) Bathe the pigs with spray or shower, 2-4 times a day to help them dissipate heat.

(2) The temperature of the water coming out of the well is low, so you can bask in the sun for a while, and then wash the pig with water, which can dissipate heat and cool down, and make the pig clean and hygienic.

(3) When washing the pig body with water, it should be arranged not to wash it within 30 minutes before feeding, nor to wash it suddenly with water to prevent the blood vessels in the pig head from contracting strongly and going into shock.

Sixth, take a bath to cool down. You can build a shallow pool in the corner of the pigsty and inject clean water, so that pigs can soak in the pool at any time to promote body heat dissipation. If the small circle digs the pond unconditionally, let the pig out at regular intervals in the afternoon and let it turn over 10-20 minutes.

Seven, diet heatstroke prevention.

(1) vinegar or sauerkraut juice. It can be taken orally every time, depending on the size of the pig.

(2) white lentils. White lentils have the effect of relieving summer heat and strengthening stomach. According to the weight of the pig, 20-50 grams is enough, and the soup is cooked.

(3) mung bean soup. Take an appropriate amount of mung beans, add 20 times of water and cook until the skin is rotten. Drink soup and beans after cooling.

(4) Watermelon skin. Use 2000 grams of fresh watermelon peel, mash it, add 100 grams of white sugar and mix well, the next day 1 time.

Eight, do a good job in pig body, pig house hygiene. Wind holes should be fully opened in the pigsty to make the pigs cool and comfortable. Sanitary sand particles with a thickness of 3-5 cm can be spread in the pigsty to dissipate heat through the contact between the pigs and the sand. Spray 20% lime milk on the walls and floors every day for disinfection, and disinfect all feeding utensils with 3% carbolic acid solution.
