In addition, the following points should be noted:
1, keep proper temperature and humidity.
Under suitable temperature and humidity conditions, pigs can reduce the stress caused by temperature and humidity, and the basal metabolism used to resist bad stimuli is low.
Step 2 drink plenty of water
Provide enough 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. Adequate drinking water is the guarantee for the normal growth of pigs, so clean drinking water can be supplied at any time, and 0.5% salt water can also be drunk.
Step 3 adjust your diet
The growth rate of pigs can be improved by adjusting the diet at different growth stages and under different environmental conditions. In midsummer, the energy feed in the diet should be relatively reduced, and the green feed can be increased. The energy feed is 50-70% of the daily diet in peacetime 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. Attention should be paid to the adequate supply of feed energy in winter, which will help pigs resist the bad stimulation of severe winter.
Step 4 eat at night
Feeding at night helps pigs gain weight. It can be fed three times a night, at 7: 00 pm, at night 1 1 point, and at 4: 00 am 1 time. As long as the feeding is reasonable, the daily gain of pigs meeting the needs of about 50 kg can reach 0.5-0.75 kg.
5. Several special feeds
(1) vinegar or sauerkraut juice: it can be taken orally every time, and the amount can be increased or decreased according to the size of the pig. (2) White lentils: It has the effect of relieving summer heat and strengthening the stomach. Depending on the weight of the pig, 20-50g can be used for frying soup and making soup. (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) Boiling Plantago asiatica and Lophatherum gracile with water, and mixing with feed to feed pigs. (5) Watermelon peel: 2 kilograms of fresh watermelon peel, mashed and mixed with sugar 1 00g, every other day1time. In addition, feed more heat-clearing feed and additives, such as wheat bran, bean cake, peanut cake and artificial salt. , can be added at will according to the conditions, and try to feed less hot feed such as sorghum, wax gourd, cottonseed and distiller's grains.
6, do a good job in health, pay attention to ventilation. The pigsty should be completely ventilated to keep the pigs cool and comfortable. Clean sand with a thickness of 3-5 cm can be spread in the shed, and it will contact with the sand through the pig to dissipate heat. Spray 20% lime milk on the walls and floors every week for disinfection, and disinfect all feeding utensils with 3% carbolic acid solution.
