| 摘要: |
| 为探索酶制剂处理水解羽毛粉提高其蛋白质利用率的效果,首先采用6个不同浓度的复合蛋白酶制剂对水解羽毛粉进行酶解。得出以1. 20 g /kg酶浓度酶解的羽毛粉,可溶性蛋白含量较高。然后采用Sibbald鸡“TME”测定法,测定用1. 20 g /kg酶浓度酶解羽毛粉的氨基酸利用率,并以水解羽毛粉和鱼粉为对照。结果表明,酶解羽毛粉氨基酸利用率显著高于(P<0. 05)水解羽毛粉,而与鱼粉无显著差异(P>0. 05)。 |

| Abstract: |
| In order to improve the availability of protein of high pressure hydrolyzed feather meal, the effect of high pressure hydrolyzed feather meal enzymolyzed
by enzyme preparation was studied in this paper.First, the hydrolyzed feather meal was
enzymolyzed by complex-protease preparation of six different concentrations.The result
showed that the amount of soluble protein in enzymolyzed feather meal by enzyme of 1. 20 g /kg concentration was higher.The availability of amino acid of this feather meal was
determined by means of Sibbalds“TME”method, and then was compared with the hydrolyzed feather meal and fish meal. The result showed that amino acid availability of
enzymolyzed feather meal was higher than that of hydrolyzed feather meal significantly
(P< 0. 05), and the difference of amino acid availability between enzymolyzed feather
meal and fish meal didnt reach significant level. |
