How to choose pig feed

Diverse and reasonable, to ensure comprehensive nutrition. In the three feeds of green feed, coarse feed, and fine feed, the green feed has a large amount of water, large volume, easy digestion, good palatability, and contains a variety of vitamins, minerals, and proteins; High fiber content and reasonable combination can increase the contact surface between feed and digestive juice, and have a laxative effect. It is easy for pigs to have a sense of fullness but is difficult to digest. The fine material is characterized by small size, high nutritional value, and easy digestion. , but lack of minerals and vitamins.

Note the relationship between dietary volume and pig feed intake. Measure the size of the feed volume and calculate the feed dry matter content. According to the calculation of 2.5 kg to 4.5 kg of feed dry matter per 100 kg of body weight per day for pigs, the dry matter of the three feeds for green, coarse and fine material needs to be 5:3:2, for example, a pregnant sow of 150 kg in weight. One-day feed dry matter is calculated at 5 kg. 2.5 kg of dry matter are from green material (6 kg of green material can have 1 kg of dry matter), 1.5 kg of dry matter are from coarse material, and 1 kg of dry matter is from fine material.

To achieve a good feed with a good palatability, easy to digest the feed, such as high energy and protein, containing less crude fiber, the palatability is good, easy to digest; on the contrary, low in energy and protein, containing more crude fiber, then the palatable Poor sex, hard to digest. In combination with pig feed, it is better to use green fodder and use less roughage, and the combined roughage requires good quality.

According to different herds, different types of diets are generally used. For finishing pigs of piglets, breeding boars and fattening stages, fine material can be used, that is, the concentrate can account for more than 50% of the total weight of the ration; breeding sows, The gilts may use the green type, that is, green feed may account for more than 50% of the total weight of the ration; shelf-fed pigs may use the gluten type, that is, bran feed may account for more than 50% of the total ration weight.
