The way of raising reserve sows

The reserve sows should pay attention to the feeding mode: high nutrition level before weight 60kg and low nutrition level after weight 60kg. In the feeding technology: the ration feeding period should account for 2.5% to 3.0% of the body weight, and after the body weight is 80 kg, the feeding amount accounts for less than 2.5% of the body weight. It can not only ensure good growth and development, but also control the rapid growth of body weight and ensure the full development of various tissues and organs. The weight of reserve sows is generally controlled at 60 to 70 kg at the age of 5 months, 80 to 90 kg at 6 months, 100 to 110 kg at 7 months and 120 to 130 kg at 8 months.
