In summer, the heat is hot and hot, and only the pigs can be safely and summerly to get the best economic benefits. Therefore, the following techniques can be used in the feeding process:
1. Adjusting the diet structure
In the midsummer period, the energy feed in the diet should be relatively reduced, increasing the green feed. Usually, the energy feed is 50% to 70% of the diet, and 40% to 50% in the summer. The green feed is 0.5 to 1 kg per head per day, and is increased to 1 to 1.5 kg. The feed should be fresh and hygienic and free of mold.
2, the implementation of night feeding pigs
Feeding pigs at night can reduce daytime activities and increase pig sleep time. In addition, the outside world has less disturbance at night and the weather is cooler. After eating, the pig can sleep for more than 18 hours a day, which is conducive to the growth of pigs. Feeding time can be carried out at 7:00, 11:00 and 4 am, feeding 3 times a night, and feeding 0.5% saline and green succulent feed once a day at 10 noon and 2 pm during the day. As long as the feeding is reasonable and meets the nutritional needs, pigs weighing about 50 kg can also gain 0.5 to 0.75 kg per day.
3, supply sufficient clean drinking water
Water is the best solvent and transportation tool for various nutrients. The elimination of waste in the body is also carried out by water. The body water of pigs accounts for 1/3 to 2/3 of the weight, and the daily water consumption of pigs in summer is 23.8%. Drink 0.5% saline to regulate body temperature.
4, feed heatstroke
The method is available:
(1) vinegar or sauerkraut juice, pig vinegar or sauerkraut juice, can reduce the body temperature of pigs in a certain period of time, so as to achieve the purpose of cooling and cooling. Each time you can take 250 ~ 500 ml orally, depending on the size of the pig body.
(2) White lentils have the effect of eliminating the heat and strengthening the stomach. According to the weight of the pig, 20 to 50 grams can be used to drink the soup with decoction.
(3) Mung bean soup, take the right amount of mung beans, add water 20 times to cook until the skin is rotten, drink soup and eat beans after cooling.
(4) Decoction with psyllium and light bamboo leaves and water, and mix with the feed to feed the pigs.
(5) Watermelon skin, 2 kg of fresh watermelon rind, mixed with 100 grams of white sugar after smashing, and fed once every other day.
