Scientific cooperation with pig feed
One must be diverse and reasonable to ensure comprehensive nutrition. In green, coarse, and fine feeds for pigs, the green material has many water contents, large volume, easy to digest, good palatability, and contains a variety of vitamins, minerals, and good quality protein; coarse and bulky, coarse High fiber content; with reasonable, can increase the contact surface of feed and digestive juice, and have a laxative effect, so that pigs have a sense of fullness, but difficult to digest; fine material is characterized by small size, high nutritional value, easy to digest , but lack of minerals and vitamins. Second, we must pay attention to the relationship between dietary volume and feed intake. Measure the size of the feed volume available for the calculation of feed dry matter content. According to the requirement of 2.5 kg - 4.5 kg feed dry matter for every 100 kg body weight of pig, the ratio of three kinds of green, coarse and fine feeds is generally arranged according to 5:3:2 air-dried matter, and a pregnant sow of 150 kg weight, Every day feed dried matter is calculated at 5 kg. 2.5 kg of air-dried material is from green material (1 kg of dry material for 1 kg of green material requires 15 kg of green material); 1.5 kg of air-dried material comes from coarse material; 1 kg is from fine material. . Third, it is necessary to make the compound feeds good palatability and easy to digest. In compound feeds, such as high energy content and protein content, and containing less crude fiber, the palatability is good and easy to digest; on the contrary, less energy and protein, and more crude fiber, poor palatability is difficult to digest. When formulating pig feed, green fodder should be used more often, and roughage should be used less, and the quality of co-cooked roughage should be better. Fourth, according to different herds, choose different types of diet. In general, pigs, breeding boars, fattening pigs can be used as finishing materials, ie, concentrates can account for more than 50% of the total weight of the diet; sows and gilts can use green materials. Green fodder may account for more than 50% of the total weight of the diet; shelf-fed pigs may use bran-type bran, which means bran feed may account for more than 50% of the total diet weight.
