Key points for attention in self-made pig feed

Core hint: family or intensive pig feeding with self-made pig feed can greatly reduce the feeding cost and improve the economic benefit of pig breeding. However, self-made pig feed must grasp the following "five keys": prepare feed according to feeding standards; pay attention to the type and proportion of raw materials; pay attention to the characteristics of raw materials; pay attention to the volume of raw materials; and mix raw materials evenly.

Domestic or intensive pig feeding with self-made pig feed can greatly reduce the feeding cost and improve the economic benefit of pig breeding. However, self-made pig feed must grasp the following "five keys":

Prepare feed according to feeding standard

The nutrient requirements of pigs are also different for different feeding purposes and different stages of pig growth and development. Therefore, pig breeding should choose different feeding standards to prepare formula feed according to different production purpose, breed, age, body weight and so on.

Pay attention to the type and proportion of raw materials

The variety of raw materials of pig formula feed should be diversified in order to give full play to the complementary role of nutrients among various raw materials. The raw material proportion of commonly used pig feed is: cereals such as corn, rice, barley, sorghum, etc., generally account for 50% to 70%; bran, such as wheat bran, rice bran, etc., should account for 10% to 20%; toxic cottonseed cake, meal and rapeseed cake should be less than 10%. Animal protein feed such as fish meal, silkworm pupa, etc., accounts for 30.7%; grass meal is less than 5%; bone meal is 20,25%, and salt is less than 0.5%. It is worth noting that breeding pigs should not use toxic cottonseed cake, meal and rapeseed cake.

Pay attention to the characteristics of feed raw materials

Master the characteristics of all kinds of feed raw materials, such as palatability, the content of toxic and harmful substances in feed, as well as whether the feed is polluted, mildew or not. The palatability is poor, and the raw materials containing toxins should be strictly limited. Seriously polluted and moldy feed raw materials should be resolutely banned to ensure feed safety.

Pay attention to the volume of raw materials

In order to ensure that pigs can take in the nutrients they need every day, the selected raw material volume and nutrition must be compatible with the digestive tract volume of pigs, so as to ensure the healthy and rapid growth and development of pigs. If the selected raw material volume nutrition must not adapt to the digestive tract volume of pigs, in order to ensure the healthy and rapid growth and development of pigs, it is necessary to consider increasing the feeding times to meet the nutritional needs of healthy and rapid growth and development of pigs.

The mixing of raw materials should be uniform

All kinds of raw materials in pig formula feed should be fully mixed and evenly mixed to ensure the intake of various nutrients for pigs. If all kinds of raw materials of compound feed are not evenly mixed, it is easy to cause drug or trace element poisoning in pigs.
