Embodiment 3:
A kind of compound premix: be by vitamin E, Mercaptamine, biotin, carrier combinations forms.The weight proportion of these several components is: every kilogram of compound premix of the present invention is by vitamin E 55g, Mercaptamine 600g, and biotin 12mg, carrier combinations forms.
Experiment: release-controlled coated cysteamine influences 1 material and the release-controlled coated cysteamines of method 1.1 test material 1.1.1 (containing cysteamine 50%) to piglet growth performance, is provided by Hangzhou Kangdequan Feed Co., Ltd; 1.1.2 experimental animal is the DLY three way cross piglet on foreign trade pig farm, Shengzhou, Zhejiang; Form 1.1.3 the test diet cooperates with reference to NRC (1998) piglet nutritional need, be processed into mash feed, its prescription and trophic level see Table 1.1.2 test method 1.2.1 feeding experiment is chosen DLY piglet healthy about 90 18 kilograms, is divided into 3 groups at random, establishes 3 repetitions for every group, 10 of every repetitions, male and female half and half.Feed respectively and add 0,125, the diet of 150mg/kg cysteamine.30 days experimental periods, free choice feeding, sufficient water supply, routine immunization and feeding and management.1.2.2 data statistics Processing Test data difference conspicuousness adopts the t method of inspection.

2 results and analysis 2.1 speeds of growth and efficiency of feed utilization
Feeding experiment the results are shown in Table 2, compare with control group, interpolation 125mg/kg and 150mg/kg cysteamine make the piglet daily gain improve 13.19% (P<0.01) and 12.31% (P<0.01) respectively in diet, make the material anharmonic ratio reduce by 12.71% (P<0.01) and 11.43% (P<0.01) respectively, but feed intake is not seen notable difference.

This result of the test shows, directly adds release-controlled coated cysteamine in feed, can significantly improve growth in piglets speed and feed efficiency, and 125mg/kg and 150mg/kg additive capacity difference are not obvious.Report in the past thinks that the suitable addition of piglet diet cysteamine is the 80-100mg/kg body weight, calculates by the average feed intake of piglet, and the addition in the daily ration is about 400-500mg/kg.And release-controlled coated cysteamine just can obtain growth-promoting effect preferably at 125mg/kg.Its detailed mechanism of action still remains further to be studied.
This test finds that also the fur of cysteamine test group pig is light comparatively, illustrates that piglet health status is better.
