For large pig farms, what kind of environment is most suitable for delivery rooms?

Sows are afraid of heat. If other factors remain normal, when the temperature is too high, it will cause heat stress, abnormal lactation and reduced food intake. As long as the standard of feed intake is not reached, the weight loss of sows during the whole lactation period will be great and the lactation quality will be reduced. With the increase of age, the environmental temperature of suckling piglets can slowly and gradually decrease by about 2 degrees Celsius every other week after birth, and it is better to control the environmental temperature of suckling piglets at about 26 degrees Celsius before weaning.

In the summer from July to September in the south, the temperature is generally between 25℃ and 35℃, and the weather is hot, which has a great influence on the feed intake of sows in the delivery room and directly affects the weaning weight and survival rate of piglets. It is particularly important to do a good job in heatstroke prevention and cooling. In summer, the microenvironment temperature mainly affects piglets (this microenvironment mainly refers to incubators), starting from about 32 degrees at birth to about 26 degrees after weaning.

The delivery room needs a "double environment". The so-called big pig is afraid of heat and little pig is afraid of cold, which is a true portrayal of this "dual environment". In production, piglets use incubators, insulation mats and insulation lamps to obtain the required high temperature (32-36℃). In cold season, the temperature of pigsty should not be lower than 65438 00℃. The pigsty should be kept at 65438 08℃. Piglets aged 2-3 weeks need about 26℃. However, piglets under 1 week need an ambient temperature of 30℃.

Controlling temperature in winter is the key to prevent piglet diarrhea. The suitable temperature of sow delivery room is about 25-26℃, sow delivery room is generally about 24℃, and the incubator of newborn piglets is controlled at about 35℃. In order to balance the health system of big pigs and small pigs, a thermometer should be hung in each delivery room. Use humidity to cool the big pig. The temperature of the big pig standing and lying is different, and the temperature near the door is different from that inside. Heat stress in pigs is essentially that the heat generated by the pig's body is greater than the heat emitted by the pig. To solve the problem, we should also come from this idea. When designing a pig farm, you can do a good job of greening around the pig farm.
