The stage fattening method of shelf pigs

Shelf pigs adopt stage fattening method: piglets are fed a high-energy and high-protein diet before 60 kilograms, with 16 to 18% crude protein in the mixture, 3.2 mega calories of digestible energy, 2 to 3 meals a day, free intake to saturation, and give full play to the advantage of fast growth of piglets in the early stage. the daily gain is more than 1 to 1.2 kilograms. In the 60 to 100 kg stage, using medium energy, medium protein, 13 to 14% of crude protein in feed, 3 mega calories of digestible energy, limited feeding of two meals a day, eating only 80% of nutrients a day, to reduce fat deposition, required daily gain of 1.2 to 1.4 jin. In order not to starve pigs, the proportion of coarse feed can be increased.
