Reduce the use of soybean cake powder (8.31)

In the United States, the standard diet for piglets in the second feeding stage after weaning is based on corn soybean cake, and the energy level of the diet is increased by adding fat For example, soybean oil 4%, corn 56% and soybean cake powder 37% were fed to 11-22 kg pigs However, in the above feed stage, restricting the use of soybean cake powder in the diet can improve the feed intake of piglets, thus improving the speed of weight gain It can also reduce the amount of fat added The shortage of energy and amino acids in the diet can be made up by adding crystalline amino acids to corn The soybean oil, soybean meal and corn were reduced to 3.60%, 32% and 61%, respectively The diets could be supplemented with crystalline lysine, methionine and threonine Therefore, the content of metabolizable energy and true digestible amino acids remained unchanged In this experiment, feed conversion rate and daily gain increased, but the difference was not significant enough In general, the feed cost of each pig can be reduced in a small amount by adopting the above feeding method Source: International pig raising 2000.3 China feed industry information network vzx (author:)
