use of enzymes

monica

It is only recently that enzymes have been used in animal nutrition, predominantly for mono-gastract  animals, such as pigs and poultry. When adiministered through the feed, enzymes generally catalyse, in the gaatrointestial tract, chemical reactions which lead to degradation of the feed ingredients. The name of an enzyme generally consists of the name of the substrate which is cleaved under the influence of the enzyme,the ending "-ase" being added.

Enzymes and enzyme complexes which are obtained by fermentation are primarily used for the following purpose:
- increasing the availability/convertibility of feed ingredients(e.g. phytase for cleaving phytate, amylase for cleaving amylose)
- degrading or destroying antinutritive substances (e.g. degradation of B-glucans in barely by the use of B-glucanase)
- supplementing/supporting endogenous enzymes (e.g. proteases in young animals with an incompletely formed enzyme pattern)

這些文字確實(shí)是打出來的，不過是照著書打出來的。 慚愧啊！

專業(yè)英語一直是個(gè)大難題，樓主可有高見:tiaotiao:

水平我深信還是當(dāng)之無愧的，那么是不是可以建議多用英語發(fā)表自己對這一專業(yè)的看法，就算最初寫得不好，長此以往并形成習(xí)慣，是不是會(huì)對語言的學(xué)習(xí)和應(yīng)用大有幫助呢？
