Optional method of pig feed

Variety reasonable assurance comprehensive nutrition in pigs green material, coarse material, three feed concentrate, green material containing water and more bulky, digestible, palatable, and contains a variety of vitamins, minerals and proteins; coarse material bulky, high crude fiber content, with reasonable, increase the contact surface feed with digestive juices, and laxative effect, easy to make sense of fullness pig, but it is difficult to digest; fine material is characterized by small size, high nutritional value, easy to digest, but the minerals, vitamins relatively scarce.

Note dietary intake volume and pig feed to measure the relationship between the size of the available volume of feed dry matter content calculations. Press pigs per 100 kg of body weight daily feed required ~ 4.5 kg 2.5 kg dry matter basis, green material, coarse material, fine material to be 5:3:2 three feed dry matter, such as a head weight of 150 kilograms pregnant sows, one day need to press the 5 kg of feed dry matter basis, then 2.5 kg of dry matter from green material (green material 6 kg of dry matter can be obtained one kilogram), 1.5 kg of dry matter from the coarse material, one kg of dry matter from concentrate.
Do feed palatability, and easy to digest with the feed, such as those containing high energy and protein and less crude fiber, it palatable, easy to digest; contrary, including low energy and protein, crude fiber, the palatability poor, difficult to digest. When with pig feed, should be more use of green fodder, less roughage and roughage with the requirements of good quality.

Depending on the selection of different types of diets of pigs in general, pigs, boars, fattening phase of fattening pigs, the choice of fine material type, that is fine material can account for more than 50% of the total weight of the diet; breeding sows, gilts can choose green material type, namely green fodder can account for more than 50% of the total weight of the diet; feeder pigs can choose type of bran, bran feed that can account for more than 50% of the total weight of the diet.
