The difference of pig feed formula in Europe and America and the parameter setting of pig feed process

      一、Characteristics of American pig feed formula:

　　1、Because corn and soybean meal is rich in resources, so the pig feed formula is mainly corn and soybean meal, and soybean meal is more used in pig feeding.

　　2、The amount of whey powder added in the teaching materials is large, up to 25%.

　　3、The addition of animal protein: fish meal (can be added to 6%), blood meal and plasma protein;

　　4、Formulation with lysine levels;

　　5、Still need to add some antibiotics in the teaching materials, do not add antibiotics in other stages;

　　6、In the Us, the amount of corn and soybean meal in the formula increased and the amount of animal protein decreased with the increase of the use age.

　　7、More than 21-22% of the protein of the conservation material;

　　8、With the increase of lysine in fertilizer, the lean meat rate of pigs increased, but the fat content decreased.

　　9、Excessive use of DDGS in the formula will make the meat soft;

　　9、Dr. Cheng recommends that soy meal should not be added more than 25 percent of the time, because 11% of the oil in soy meal is indigestible, and using soy protein concentrate or fermented soy meal reduces the indigestible content to 6 percent.

　　二、European pig feed formula features:

　　1、Corn and soybean meal is scarce, and the formula is mainly barley, wheat and oats, so corn is almost invisible.

　　2、Adding wheat to pregnant and lactating sows can increase the content of crude fiber, which is helpful for sows to produce satiety and relieve constipation. The crude fiber level is recommended to be above 6%.

　　3、Formula at the net energy level;

　　4、In Europe, antibiotics are not allowed, so add essential oils - medium chain fatty acids (MCFA) - to your preservatives

　　三、Functions of medium chain fatty acids:

　　1、The shorter the chain of fatty acids, the better the bactericidal effect against gram-positive bacteria. Conversely, the longer the chain, the better the bactericidal effect against gram-negative bacteria, so it is best to use compound (hexanoic, caprylic, decanoic, lauric)

　　2、Medium chain fatty acids for the gastrointestinal tract: kill pathogenic bacteria, reduce the possibility of infection; Reduce the invasion of pathogenic bacteria; Reduce the activity of non-killing pathogenic bacteria;

　　Medium chain fatty acids for the body: change the intestinal morphology; Improve feed conversion rate; Improve immune function; Ensure a high quality of immunity;

　　四、How should the main parameters of pig feed processing be set?
