Fermenting Beds Note on Pig Raising in Summer There is no special requirement for the summer breeding of the goldfish fermentation bed, and the basic and common feeding methods have the same precautions. The optimum temperature for growing pigs is 18-25 °C. Since pigs do not have sweat glands and there is a layer of fat under the skin, it is difficult for pigs to dissipate heat. In the summer, high temperature, high humidity, and strong solar radiation have caused great adverse effects on pig production. In order to maintain the pig's growth and production performance in hot summer and reduce the loss of heat stress, the majority of farmers must fully consider the harm of high temperature on pigs, and take effective measures to reduce heat and heat. The following are recommended 10 practical techniques for raising pigs in the summer:
1. Strengthen ventilation: The most important aspect of breeding pigs is “ventilationâ€. In high temperature environment, the pig's blood flows to the skin, the pig's body surface temperature is high, and enhanced ventilation can increase the heat away from the body surface and help to dissipate heat. Suggested measures: Open the north and south windows of the pig house (a window with a floor to a window); For pigs with hot and stressed pigs and lactating sows, consider adding ceiling fans to enhance ventilation and heat dissipation.
2. Reducing heat radiation: Heat radiation is a very important heat source for increasing the calories of pigs. Do not ignore the negative effects of heat radiation. Thermal radiation includes direct sunlight seen from the see, but also includes invisible infrared radiation. In order to reduce direct sunlight, the sun must not be allowed to shoot directly into the body during the summer; for reducing infrared radiation, the roof of the pig house should be insulated (for example, with a foam board ceiling) to reduce the radiant heat of the roof; in short, take measures to prevent The roof is too hot and eventually controls the room temperature of the fermentation bed.
3. Increase the evaporative heat dissipation of pigs: Although pigs do not have sweat glands, they can wet the body surface and reach the goal of evaporative heat dissipation. It is recommended that the pig should be sprayed and cooled properly at the hottest time of the day. This will not only reduce the dust generated due to drying, but also reduce the body surface temperature of the pig. However, remember that the humidity is not too high, and the fermentation bed is not afraid of wetness. Control the moisture!
4, pay attention to drinking water: hot summer, the pig's drinking water increased significantly. Ensuring adequate drinking water is very important for relieving heat stress. Suggestion: Keep pigs drinking water frequently. It is best to have automatic drinkers (flow rate of drinking fountains, more than 1 litre per minute for sows); keep the temperature of drinking water as cool as possible (water directly from underground deep wells is best; prevent water pipes Water tank under the sun, causing drinking water too hot);
5, reduce the rearing density: Golden Dolphin fermentation bed requires 1.2 to 1.5 square meters to raise a pig, the summer pig to heat, the body is fully stretched, the breeding density is not conducive to the pig's heat, so the majority of product users must be raised as required to ensure fat pig The lying area is 1.2~1.5 square meters.
6, appropriate to improve feed nutrient concentration: In high temperature conditions, the pig's appetite and feed intake decreased significantly, directly reduce the pig's production performance, especially the biggest impact on lactating sows. Therefore, in addition to piglets, it is recommended to raise the protein and amino acid levels of feed by 1-2%; at the same time, increase the vitamin supplementation level; minimize the proportion of indigestible, heat-producing roughage in the feed (for example, do not feed or Reduce the use of grass powder and reduce bran; summer pigs have low digestibility (because the high temperature distributes blood to the skin, and the blood allocated to the digestive tract decreases), and it is advisable to feed digestible feeds. It is also recommended to add enzymes to the feed. Increase the digestibility; add about 0.5% baking soda to pig feeds except piglets to alleviate the acid excess caused by heat stress and maintain acid-base balance in the body.
7. Adjust feeding methods: The key to feeding in the hot season is feed intake. The main task of feeding is to allow the pig to eat the ideal amount of feed as much as possible. If we let it go, pigs may eat too little. The result is that the pigs are not long, the sows have no milk, and the resistance to disease is greatly reduced. Suggested feeding methods: Use wet material as much as possible to feed the pig (Practice proves that the wet material feeds the pig, the pig eats fast, the body heat is less, the heat stress is light, the feed intake is much); in a relatively cool time of day Feeding pigs (a day's temperature changes around 10 °C, if you still feed the pigs in winter, the pigs are not appetitive at noon and afternoon temperatures. It is recommended to feed the pigs early in the morning, feed them at noon, and late in the afternoon. Feeding pigs can be fed once at night. Carefully feed the pigs and don't add ground. There shouldn't be leftovers in the troughs, otherwise the feeds will not be eaten by the bad pigs.
8, to maintain the fresh feed and palatability: high temperatures in the summer, the feed is likely to mold deterioration, a great impact on the pigs. Suggestion: The feed should not be stored for a long time; crushed and processed feeds are more likely to be mildewed, it is recommended to feed the pigs now; the mycotoxin adsorbent can be added to reduce the harmful effects of mycotoxins, such as the feedstuffs fed by the Golden Baby II feed starter fermentation more.
9. Maintain pig house hygiene and pig health: Because of the cleanliness of the bed, the pigs rarely get sick, but in the summer the bacteria multiply very quickly. Once the pig is infected with the disease, the pig's fever and not eating may lead to serious consequences. , even an outbreak of the disease. Therefore, it is recommended to strengthen hygiene and disinfection work during the high temperature season (Goldbread fermentation bed can be normally sterilized).
10. Reducing Other Stresses: Modern pigs have very low stress resistance, and stress increases the secretion of stress hormones (such as adrenocorticotropic hormone) in pigs. It not only increases the heat production of pigs, but also increases the heat burden on pigs, and it also reduces Pig immunity. It is recommended to minimize the stress on the pigs. Be sure to treat the pig tenderly. Do not act rough, mix the groups frequently, feed at a time of confusion, and suddenly change the feed, people, and the environment.
