What causes deformed oyster mushrooms?
The occurrence of deformed oyster mushrooms should be largely related to the large temperature difference between day and night. Since the onset of winter, temperatures have remained low. To make oyster mushrooms grow quickly, many mushroom growers deliberately raise the shed temperature during the day. Generally, after about three in the afternoon, because ventilation continues, the temperature inside the shed begins to drop rapidly. Since most of the mushroom sheds currently in use are rather simple and poor at retaining heat, at night the temperature can fall to 4-5°C or even lower. Because the temperature is low, the substrate temperature is low. Therefore, the ability of the mycelium to transport nutrients is very poor, and during the day, when the temperature is briefly higher,

Reasonable pig feed formulation is the only way to prevent pigs from losing their appetite
When the temperature rises above 35°C, pigs have low feed utilization and slow weight gain. Therefore, in hot seasons, different feeding methods should be given according to different categories of pigs and different physiological stages of pigs. Boars: feed 2 times a day, and add green feed or thin feed at noon. Mating and exercise are both carried out in the morning and evening; after mating, do not immediately let them go into water to wallow or spray them with cold water. From 1 p.m. to 3 p.m. every day, spray water once on the pigs' bodies and the ground, and reduce light to 8-10 hours. If the number of matings is low, the amount of concentrated feed should be reduced to prevent overfattening and poor libido.
