The three elements of scientific raising pigs

Science is of three elements: a good pig: appropriate temperature, humidity and light.

The suitable growth temperature of newborn piglets is 34 ℃ ~ 35 ℃;3 ~ 4 weeks of piglet suitable growth temperature is about 30 ℃;Larger piglet suitable growth temperature is 20 ℃ ~ 23 ℃;A pig growth of optimum temperature is 17 ℃ ~ 22 ℃.Under the appropriate temperature, the growth of pig carcass fat and lean meat is normal, in the high temperature and low temperature environment, slow growth of the fat.When raising lean hogs, therefore, should try to give the pig to create appropriate temperature environment.

The condition of high temperature, high humidity may slow down weight to pigs, with a high mortality rate.Under the condition of low temperature, high humidity, get heat intensifying, the pig weight decreased by 36%, litter size decreased by 28%, per kilogram weight loss is expected to increase by 10%.

Mild and moderate light, good for growth of young pigs and pig breeding.Young pigs often contact sunshine, can strengthen the blood circulation, accelerate metabolism, promote cell proliferation and bone growth, increase the speed of development.Sows, often exposed to direct sunlight can accelerate the development of the egg, promoting estrus ovulation, increase fertility.But the illumination time is too long, easy to make pig activity increases, have an effect on weight gain.

In addition, also has effect on the normal fertility of airflow to the pig.Good air convection in piggery, when high temperature cooling;If the air circulation, adverse to the pig, low temperature, airflow into the cold, but also to the pig.
