Difference between premix and concentrate

  Premix: premix is a kind of intermediate compound feed product composed of vitamins, minerals and carrier in a certain proportion
The nutrients contained in it can be effectively attached to the carrier after pretreatment, but additional energy feed and protein feed are needed to ensure the normal metabolism, growth and breeding of animals

Advantages: relatively low cost; It can ensure the purchase quality of additional corn and soybean meal, avoid the impact of mycotoxin on breeding, and flexibly use rice, sweet potato and wheat to replace energy feed corn, and sesame meal and peanut meal to replace protein feed soybean meal, which can make full use of local agricultural and sideline products to reduce feeding costs; Daily * addition, such as Chinese herbal medicine, probiotics and feed peptides, is convenient and easy

Disadvantages: the amount of labor increases, which increases the labor cost; We need to stock raw materials and increase the investment of certain funds

Concentrate: concentrate refers to the feed made by mixing various protein raw materials (such as fish meal and soybean meal) with a certain proportion of premix according to the livestock and poultry feeding standards
The protein content in the concentrate is more than 35%, and the contents of various essential amino acids, vitamins and inorganic salts are sufficient, so it is not necessary to add them separately

Advantages: when the price of soybean meal is high, the feeding cost can be reduced; There is no need to buy extra soybean meal, which reduces the amount of labor

Disadvantages: the cost is 0
1-0
2 yuan / kg higher than that of premix; The content of soybean meal is low, which is suitable for feeding local varieties

Full price material: full price material is a mixture made of protein feed (such as fish meal, beans and other meal), energy feed (such as corn, wheat and rice), roughage (such as wheat bran and straw, which are only used in low standard mixture) and premix through crushing, mixing and granulation
Directly used for feeding livestock and poultry, it can fully meet the nutritional needs of feeding objects

Advantages: pellet feed is convenient; Easy storage and low moisture; It is not easy to waste compared with powder; The cost of manpower and material resources is relatively low; The full price material is matured, digested and absorbed better, and the full price material grows rapidly

Disadvantages: high cost, 0
2-0
4 yuan / kg more expensive than premix; Uncontrollable composition of feed; Granulation at a high temperature of 70-90 degrees will destroy vitamins (the titer will be reduced by about 50%), reduce the activity of acid and enzyme preparations by about 80%, and reduce xylanase by 90%; It is difficult and uneven to add medicine for treatment and prevention * and it needs to be comminuted again
Add medicine in the medicine pot and mix the concentrated material inside, and the meat is fat

Combined with the advantages and disadvantages of these feeds, the most suitable way for rural farmers is premix feeding, which has relatively low cost and convenient feed sources
However, it is worth noting that premix can not be used as the only feed source to promote animal growth and development
Some corn energy feed and soybean meal protein feed must be added to ensure the comprehensiveness of nutrition
