| The present experiment concentrated on effects of choline on vitamin stability by making wrapped choline chloride (WCC), a preservation experiment, and a feeding animal experiment. The experiment of making wrapped choline chloride, contrast WCC and choline chloride from market(CCM) in contain, saturation rate of sucking up moisture, and dissolved rate in water, mainly. The preservation experiment including three small experiments:In the trail I , A 4 X 2 factorial design is adopted to test the stability effects of WCC, CCM and soybean on vitamin ,in condition of different storage factions. In the trail II, A 3 X 2 X 2 factorial design is adopted to test the stability effects on vitamin ,in the zeolite-carried and stone meal-carried premixes. In the trail III, A 3 X 2 X 2 factorial design is adopted to test the?stability effects of choline chloride ,storage faction and the kind of carriers on vitamin ,in the condition of trace elements. A 2 X 2 X 3 factorial design is adopted to test the effects between choline chloride, vitamin, and storage time on production performances of broilers in the feeding animal trial. The results of making 慦CC were as follows, WCC and CCM contain 46.21%, and 43.38%, respectively. Contain of WCC is more 6.12% than CCM (P<0.05). Saturation rate of absorption moisture of WCC was 26.98%, and it of CCM was 28.81%, CCM was more 6.35% than 1VCC, and saturation rate of absorption moisture had a significant difference (P<0.05). The results of dissolved rate showed, with PVB dissolving, 42.87% choline chloride had dissolved for twenty minutes, at fifiy minute,95.89% choline chloride had dissolved ,and that showed WCC could be absorbed and utilized by the animals. 1. The results of the trail I showed , choline chloride had apparent effects on vitamin A (VA) and vitamin B2 (VB2). The average losing rates of VA in premixes including WCC, CCM and soybean were more 75. 02% (P<0.05), 78.16% (NO.05) and 59.15% (P<0.05) than them in premixes without choline chloride, respectively. With the storage time running, the losing rates of VA increased, but them in CCM-premixes were more than them in ~CC-premixes in the storage same time, and there had significant difference between CCM-premixes and IYCC-premixes for two months. The average losing rates of VB2 in premixes including WCC, C~M and soybean were more 74.06% (NO.05), 74.57% (NO.05) and 52.33% (NO.05) than them in premixes without choline chloride, respectively. There had no significant difference on the losing rates between CCM-premixes and WCC-premixes through the storage time. In addition there had significant effects on VA, but there had no significant effects on VB2 in storage ways. 3 2. The results of the trail II showed, the losing rates of VA in CCM-premixes, IVCC-premixes and premixes without choline chloride were 12.59%, 11.07% and 5.46% on condition that there were two carriers- zeolite stone meal in different premixes, and the losing rates of VA in WCC梡remixes and CCM premixes were more 50.68% (P<0.05) and 56.63% (NO.05) than them in premixes without choline chloride. The losing rates of VA in WCC-premixes were less than them in CCM-premixes, in the same time, so there had significant difference between WCC梡remixes and CCM-premixes after two months. The losing rates of VB2 in CCM-premixes, WCC-premixes and premixes without choline chloride were 11.99%, 10.78% and 7.19%, and the losing rates of VB2 in YCC梡remixes and CCM-premixes were more 33.21% (P<0.05)... |
