What are the key points to note when mixing pig feed yourself?
Core tip: For household or intensive pig farming, using self-mixed pig feed for feeding can greatly reduce feeding costs and improve the economic benefits of pig farming. However, when mixing pig feed yourself, you must grasp the following "five key points": formulate feed according to feeding standards; pay attention to the types and proportions of raw materials; pay attention to the characteristics of feed raw materials; pay attention to the volume of raw materials; and mix raw materials evenly.
For household or intensive pig farming, using self-mixed pig feed for feeding can greatly reduce feeding costs and improve the economic benefits of pig farming. However, when mixing pig feed yourself, you must grasp the following "five key points": Formulate feed according to feeding standards Different feeding purposes and different stages of pig growth and development mean that pigs have different requirements for nutrients. Therefore, when raising pigs, different feeding standards should be selected to formulate compound feed according to different production purposes, breeds, days of age, body weight, and so on. Pay attention to the types and proportions of raw materials The raw material varieties for pig compound feed should be diversified so as to give play to the nutritional complementary effect among various raw materials. The commonly used raw material proportions for pig feed are: grains such as corn, rice, barley, sorghum, etc., generally should account for 50~70; bran and middlings such as wheat bran, rice bran, etc., generally should account for 10~20%; toxic cottonseed cake, meal, and rapeseed cake, etc., should be less than 10%. Animal protein feeds such as fish meal and silkworm pupae account for 3~7%; grass powder less than 5%; bone meal 20~25%, and salt should be less than 0.5%. It is worth noting that breeding pigs should not use toxic cottonseed cake, meal, rapeseed cake, and so on. Pay attention to the characteristics of feed raw materials Grasp the characteristics of various feed raw materials, such as palatability, the content of toxic and harmful substances in the feed, and whether the feed is contaminated or moldy. Raw materials with poor palatability and containing toxins should be strictly added in limited amounts. Severely contaminated and moldy feed raw materials must be resolutely prohibited to ensure feed safety. Pay attention to the volume of raw materials In order to ensure that pigs can intake the nutrients they need every day, the volume and nutrition of the selected raw materials must be compatible with the volume of the pig's digestive tract, so as to ensure healthy and rapid growth and development of pigs. If the volume and nutrition of the selected raw materials are not compatible with the volume of the pig's digestive tract, in order to ensure healthy and rapid growth and development of pigs, consideration should be given to increasing the number of feedings to meet the nutritional needs for healthy and rapid growth and development of pigs. Raw materials must be mixed evenly Various raw materials in pig compound feed must be fully and evenly mixed to ensure that pigs intake the various nutrients they need. If the various raw materials of the compound feed are not mixed evenly, it is very easy to cause pigs to be poisoned by drugs or trace elements.
