Study on The Efficient Utilization and Cost-Effectiveness Technology Scheme of Sucrose Chelated Trace Elements for Pigs

利用蔗糖螯合有机微量元素制定商品猪节本增效实用方案,以硫酸盐为参比,通过4次小试、2次中试和2次生产推广,累计60万头商品猪的不同层次的试验研究,通过元素平衡试验、体内沉积量和组织抗氧化指标测定,确定了铁、铜、锌、锰综合生物学利用率分别提高21%、18%、18%和8%以上。通过4个批次的能量和养分净利用率评估研究,确定了蔗糖螯合有机微量元素可以释放的商品猪配方营养参数值分别为:消化能32~64 kcal/kg,粗蛋白2.0%~3.0%,赖氨酸2.0%~3.0%,蛋氨酸0.5%~1.0%,色氨酸2.0%~4.0%,精氨酸1.0%~2.0%,组氨酸2.0%~5.0%,亮氨酸4.0%~5.0%,异亮氨酸0.5%~1.0%,苏氨酸2.0%~3.0%,缬氨酸3.0%~5.0%。制定出了商品猪的蔗糖螯合有机微量元素节本增效实用方案。

To study the technical scheme of high biological availability and increase efficiency by reducing costs of sucrose chelating trace elements in pigs A total of 600000 commercial pigs were used to 4 initial tests,2 final tests and 2 produc⁃tion application,to study biological utilization of sucrose chelating trace elements,by the measurement of the nutrients absorptivity,trace elements deposited and antioxidant indexes.The study were de⁃termined the biological utilization of sucrose chelatediron,copper,zinc and manganese was increased by 21%,18%,18%and 8%,respectively,compared to the corresponding sulfate.Through four net energy and nutrient utilization studies,provedsucrose chelating organic trace elements can reduce the pig digest⁃ible energy 32-64 kcal/kg,crude protein 2.0%-3.0%,lysine 2.0%-3.0%,methionine 0.5%-1.0%,trypto⁃phan 2.0%-4.0%,arginine 1.0%-2.0%,histidine 2.0%-5.0%,leucine 4.0%-5.0%,isoleucine 0.5%-1.0%,threonine 2.0%-3.0%and valine 3.0%-5.0%.The research determined the technical scheme of high biological availability and increase efficiency by reducing costs of sucrose chelating trace ele⁃ments in pigs.
