饲料中蛋白质的问题分析

发布日期:2016-04-27 11:51 来源:http://www.zdslgs.com 点击:

蛋白质是猪生长发育中不可缺少的营养素,缺乏它,生长受阻,发育不良,于是很多养殖户在选择饲料时首先看蛋白,认为蛋白质高,质量就好。
Protein is an indispensable element in the growth and development of pigs, lack of it, growth is blocked, poor development, so many farmers in the choice of feed, the first look at protein, that the protein is high, the quality is good.
因此,很多饲料企业为迎合养殖户的消费心理,有的在标签上作文章,明明粗蛋白只有36%,却写成40%;有的在饲料中添加质量较差的血粉、羽毛粉或非蛋白氮,使饲料中的粗蛋白含量很高,而饲料质量很差。事实上蛋白质的营养最终是氨基酸的营养,况且蛋白质的大量沉积需要能量作后盾,只有饲料中可利用的必需氨基酸含量高且平衡、能量含量高的情况下,饲料中的蛋白质质量才高,蛋白质才能充分利用。
Therefore, a lot of feed enterprises in order to meet the farmers' consumption psychology, some on the label the, obviously crude protein only 36%, was written in 40%; some in the feed to add the poor quality of blood meal and feather meal or non protein nitrogen, the content of crude protein in feed is very high, and feed quality is poor. In fact the protein nutrition is ultimately the amino acid nutrition, besides a lot of protein deposition requires energy behind, high energy content and can be used to feed only the essential amino acid content is high and the balance, only high quality protein feed, protein can be fully utilized.
例如血粉,虽然其粗蛋白含量在80%以上,但因其消化率低,氨基酸不平衡,质量较低。再者,饲料中的蛋白质较高,而能量较低的话,蛋白质不能充分利用,不但不利反而有害。
For example, blood meal, although the crude protein content of more than 80%, but because of its low digestibility, amino acid imbalance, low quality. Moreover, the protein in the diet is higher, while the energy is lower, the protein can not be fully utilized, it is not only harmful but harmful.
