Effect and effect of Environmental temperature on Pig growth

Raising pigs

The production of fattening pigs has a certain adaptability to the environmental temperature of pig sheds. Too high, too low or alternating cold and heat will cause respiratory syndrome, white dysentery and other nutritional deficiencies and other diseases in finishing pigs. The alternation of cold and heat, sudden change of temperature and instability will affect the production performance of pigs to some extent.

Heat stress has a serious effect on the production of fattening pigs. too high temperature will lead to a decrease in feed intake, slow weight gain, and even increase the incidence of acute sudden death and increase the mortality of fattening pigs. such as gastrointestinal bleeding, acute gastric volvulus and death caused by acute heart and lung diseases, which bring huge losses to the production of fattening pigs. At the same time, too high temperature is also easy to breed pig house bacteria, which increases the incidence of fattening pigs.

In the cold season, due to the low temperature, productive finishing pigs are easy to suffer from all kinds of respiratory diseases and intestinal digestive diseases because of the simplicity of sebum and digestive system. The respiratory diseases of growing and fattening pigs can be easily caused by unstable temperature, dry and wet environment and ventilation in pig sheds. The main clinical manifestations are cough, asthma and respiratory acceleration, body temperature is generally not high, appetite is good and sometimes bad, growth and development is slow. Some acute respiratory diseases can lead to death.
