摘要
为揭示蛋氨酸锌在山羊体内存留与分布的规律，将１０头体重为９ｋｇ左右的健康浏阳黑公山羊分成两组，分别饲喂６５Ｚｎ－Ｍｅｔ与６５ＺｎＳＯ４两种不同来源的同位素锌，研究螯合盐中锌在山羊体内的分布与存留．结果表明：在试验前期体内富集的锌，蛋氨酸锌组为４８．４１ｍｇ，硫酸锌组为３５．４０ｍｇ，前者比后者多富集１３．０１ｍｇ，存留率分别为４０．３７％与２９．５０％．各组织器官中锌的存留量分别为２．３６，１．３０ｍｇ，蛋氨酸锌组比硫酸锌组多存留８１．５４％，差异达显著水平（ｐ＜０．０５）．两组在组织器官中锌的分布规律几乎相同，单位含量均以肝、脾、胰含量高，骨、蹄含量低．停止饲喂６５Ｚｎ后的第３ｄ，两组山羊体内存留趋于平衡，６５Ｚｎ－Ｍｅｔ与６５ＺｎＳＯ４分别为４．８８ｍｇ与４．７４ｍｇ，在组织器官中的存留量分别为２．０７ｍｇ与２．３６ｍｇ．
Ten healthy Liuyang black goats,male,9 kg per one,are divided into two groups. They are fed with 65 Zn Met and 65 ZnSO 4 respectively. This aims at studying the remains and distribution of Zn,from chelate salt,in their bodies. The result shows that before the experiment every goat,fed with 65 Zn Met,has 48.41 mg of Zn in its body,while the goat,fed with 65 ZnSO 4,has 35 40 mg of Zn. The former is 13 01 mg more than the latter. As for the remaining rate of the two groups,it is 40 37% and 29 50% respectively. In the goats tissues and organs,the remaining Zn of the 65 Zn Metgroupis2 36mg,whichis81 54%morethanthe 65 ZnSO 4 groupwhichis 1 30 mg. From this,the gap between the two can be seen clearly (p<0 05). On the contrary,in their tissues and organs,the distribution law of both groups are terribly close to each other. Unit content in liver,spleen and pancreas is high,while in bone and hoof is low. The third day after the goats are fed with 65 Zn,Zn in the goats of both groups reaches almost the same level. One is 4.88 mg,the other is 4.74 mg,and the remains in organs is 2.07 mg and 2.36 mg respectively.
