摘　　要：本试验旨在通过研究1～30日龄关中奶山羊羔羊的必需氨基酸营养需要,为建立和完善关中奶山羊饲养标准提供基础参数。选择1日龄关中奶山羊羔羊32只(公母各占1/2),每只为一个重复,按照预先设计的鲜奶+补饲料的人工培育方案进行饲养试验,采用析因法进行必需氨基酸营养需要量研究。经统计分析建立了1～30日龄关中奶山羊羔羊10种必需氨基酸需要量与代谢体重、平均日增重间的回归方程,并据此提出了不同体重(4、6和8kg)和不同日增重(0、100、150和200g/d)条件下关中奶山羊羔羊10种必需氨基酸营养需要量推荐标准。The requirements of essential amino acids for Guanzhong dairy goat kids at the age of 1～30 days were studied to provide the basal parameters for the establishment and improvement of the feeding standard of Guanzhong dairy goat kids. Thirty-two Guanzhong dairy goat kids （half male and half female） at 1 day old were selected and each was a replicate. These kids were fed pre-designed scheme of milk＋supplemetation. The requirements of amino acids were analyzed by factorial method. By statistical analysis,regression equations were established between the requirement of 10 kinds of essential amino acids,metabolic weight,and average daily gain. According to these equations,the amino acids requirements were estimated and a recommendation was proposed under different body weight （4,6 and 8 kg） and different daily gain （0,100,150 and 200 g/d） for Guanzhong dairy goat kids at the age of 1～30 d.
