Science in Pig feeding

Scientific pig raising advocates live feeding with less loss of nutrition, which not only improves the labor efficiency of raising pigs, but also reduces the production cost of raising pigs. There are many methods of raw feeding, and the feed can be made into dry powder, wet mix, water and pellet. The pellet is to press the mixed feed or compound feed into strips of different sizes with a feed granulator. It is easy to feed pigs with pellet feed, which can avoid pig food selection and ensure the full price of feed nutrition and the palatability of feed. The specific methods are as follows:

One is limited feeding. The pig diet is controlled in a certain amount of sub-feeding. The effect of limited feeding on empty and pregnant sows, boars and growing-finishing pigs (later stage) is better, but attention should be paid to timing, quantity and quality.

Timing refers to fixed daily feeding time, generally feeding piglets 4 times per day, lactating sows 3 times, and other pigs 2 times 3 times; regular feeding refers to fixed daily and each feed amount, which should be stable, when more and less, suddenly and suddenly less; quality is to pig feed quality should be strict requirements, diligent inspection, to ensure feed hygiene, non-toxic, stable quality, can not be fed moldy and deteriorated feed. The feed mix of pigs should not change too much, but should be increased or decreased gradually.

Second, unlimited feeding. Refers to allowing pigs to eat at will, generally loading one week or several days of compound feed into an automatic trough, allowing pigs to eat freely without restriction, in order to meet the nutritional needs of pigs. Unlimited feeding is usually used for piglets, growing-finishing pigs (Prophase) and lactating sows to give full play to the growth and production potential of pigs. It can not only increase the weight gain rate or milk yield of pigs, but also reduce the production cost of raising pigs.
