What is the effect of temperature on the growth of piglets? Temperature has the greatest influence on the whole process of growth and development of piglets. It was proved by the experiments of relevant departments that the most suitable temperature for the growth and development of piglets was 3035 ℃ in 1 to 3 days, 28 ℃ in 7 days, 22 ℃ in 30 days and 20 ℃ in 45 days. When the weight of piglets is over 15kg, 2025 ℃; 50`100kg, 1020℃; 1518kg. Air temperature has the greatest influence on the whole growth and development of piglets. It was proved by the experiments of relevant departments that the most suitable temperature for the growth and development of piglets was 3035 ℃ in 1 to 3 days, 28 ℃ in 7 days, 22 ℃ in 30 days and 20 ℃ in 45 days. When the body weight of piglets is more than 15kg, 2025 ℃; 50`100kg, 1020℃; 100kg, 150018 ℃, when the temperature is above or below the above range, the growth rate of piglets will be affected and slowed down. Therefore, in summer, we should pay attention to the ventilation and cooling of the piggery and the cold feeding. When fattening pigs, it is better to have a dark pigsty, so that pigs can sleep more and gain weight. In winter, pay attention to shelter from the wind and keep warm, hot and dry feeding, increase the number of feeding, when the cold air down, should let pigs eat well.
