The right amount of feed ingredients in science, we should pay attention to feed the scientific feeding, to its full potential weight gain and improve feed utilization. General Growth fattening concentrate ration by about 4 percent weight pig feed, pigs at 60 kg after 3.5% of their body weight can feed can also be determined according to the expected utilization is expected to average daily gain and feed that daily gain × feed efficiency = day feeding amount.

Suitable for feeding pigs according to preliminary growth slow, medium fast, slow growth and development of the law of the late and should be taken straight fattening rearing methods, in order to shorten the breeding cycle, saving feed. At the same time, to implement fine, green, coarse feed mix, and the implementation of the influx of students feed mix.

Pig drinkers.

Pens suitable temperature to keep clean and dry, warm winters favorable, favorable summer heat, pig create a suitable environment for the growth, to reduce the incidence of the disease, reduce consumption, improve feed utilization. Suitable temperatures are generally pig is 17 ℃ ~ 21 ℃, too high or too low for feed efficiency are adversely affected.

Appropriate vaccination and deworming blight do to minimize the incidence, in order to improve feed utilization. In pig production, each year a considerable number of pigs suffering from chronic diseases and parasitic diseases caused by recessive waste feed situation is more prominent. For this reason, good planning and regular deworming immunization can ensure healthy growth of pigs.

Timely slaughter in the early growth stage, rapid growth of bones and meat, feed utilization is high; and with the increase of age and body weight, fat growth than meat, and the long one kilogram of fat needed to feed longer than one kilogram of lean meat more than 2 times higher. Therefore, the longer the feeding period, the heavier the weight, the lower the efficiency of feed utilization. Suitable general hybrid pig slaughter weight is 90 kg to 100 kg.
