Family or intensive pigs, fed with self-contained pig feed, can significantly reduce feeding costs. In order to improve the economic benefits of raising pigs, we must grasp the following "five notes": 84B China Feed Industry Information Network - based on feed, serving animal husbandry
Pay attention to the standard preparation of feed
Pigs have different nutrient requirements for different feeding purposes and different stages of pig growth and development. Therefore, pigs should be selected according to different production purposes, varieties, age, weight, etc., to choose different feeding standards to prepare compound feed. Standard to prepare compound feed.
Pay attention to the type and proportion of raw materials
The raw material varieties of pig compound feed should be diversified to play a complementary role in nutrition between various raw materials. The proportion of raw materials for commonly used pig feed is: cereals such as corn, rice, barley, sorghum, etc., generally should be 50% to 70%; bran such as wheat bran, rice bran, etc. should generally be 10% to 20%; The proportion of cotton cake (粕) and rapeseed cake should be less than 10%. Animal protein feeds such as fish meal, silkworm cocoons, etc. are 3%~7%; grass powder is less than 5%; bone meal is 20%~25%, and salt is less than 0.5%. It is worth noting that it is not advisable to use toxic cotton cakes (èœ) and rapeseed cakes.
Pay attention to the characteristics of feed ingredients
Master the characteristics of various feed ingredients, such as palatability, the content of toxic and hazardous substances in the feed, and whether the feed is contaminated or mildewed. Poor palatability, raw materials containing toxins should be strictly limited. Seriously contaminated, mildewed feed ingredients should be resolutely banned.
Pay attention to the volume of raw materials
The selected raw material volume should be adapted to the pig's digestive tract volume to ensure healthy and rapid growth and development of the pig. Otherwise, consider increasing the number of feedings to meet their nutritional needs.
Pay attention to the uniform mixing of raw materials
The various raw materials in the compound feed should be thoroughly mixed to ensure the various nutrients required for the pigs to ingest. The uneven mixing of the raw materials can easily cause poisoning of pig drugs or trace elements.

Black Wire
Black annealed wire, which is made of low carbon steel or iron, is often applied for weaving, baling in home use and construction. For example, baling hay in agriculture area.
Black annealed wire is mainly processed into coil wire, spool wire or big package wire. Or further straightened and cut into cut wire and U type wire. Compared with black Iron Wire, black annealed wire is more softer and has higher flexibility.
