摘　　要：本试验旨在研究饲粮阴阳离子平衡(DCAB)值对绒山羊生长性能、血清和尿液生化指标及尿结石发病情况的影响。选取年龄(1.5岁左右)、体重(30 kg左右)相近的健康雄性辽宁绒山羊50只,随机分为5组,各组DCAB值分别为0(Ⅰ组)、150(Ⅱ组)、300(Ⅲ组)、450(Ⅳ组)、600 m Eq/kg DM(Ⅴ组),每组10只。预试期15 d,正试期90 d。结果表明:1)DCAB值对平均日增重影响不显著(P>0.05);随着DCAB值的提高,平均日采食量总体呈上升趋势(除了第75~90天);料重比,第1~15天、第15~30天Ⅰ组较高,第60~75天、第75~90天Ⅴ组较高。2)第75、90天时,Ⅴ组血清尿素含量最高,Ⅲ组尿液尿素含量最高;第60、75天时,Ⅴ组血清肌酐含量最高,第90天时,Ⅳ组最高;第15、30、45天,Ⅴ组尿液肌酐含量最高;第45天时,Ⅲ组血清尿酸含量最高,第75、90天时,Ⅴ组血清尿酸含量最高;第15、30天时,Ⅴ组尿液尿酸含量最高,第75、90天,Ⅲ组最高。3)Ⅰ、Ⅱ组无患尿结石羊,Ⅲ、Ⅳ、Ⅴ组分别有3、4、5只患尿结石羊。综合得出,DCAB值为150 m Eq/kg DM时,有利于维持辽宁绒山羊血清和尿液部分相关生化指标在正常水平及预防尿结石的发生。This present experiment was conducted to determine the effects of dietary cation-anion balance（ DCAB） value on growth performance,biochemical indices in serum and urine,and incidence situation of urolithiasis of Liaoning cashmere goats. Fifty healthy male Liaoning cashmere goats at the age of about 1. 5 years and body weight of about 30 kg were selected and randomly divided to 5 groups,each group had 10 goats. DCAB value in different groups was 0（ group Ⅰ）,150（ group Ⅱ）,300（ group Ⅲ）,450（ groupⅣ） and 600 mEq/kg DM（ group Ⅴ）,respectively. The pre-test lasted for 15 d,and the formal test lasted for 90 d.The results showed as follows： 1） DCAB value had no significant influence on average daily gain（ P0.05）; with the increase of DCAB value,average daily feed intake tended to increase（ excepte day 75 to90）; feed to gain ratio was higher in group Ⅰ on day 1 to 15 and day 15 to 30,and was higher in group Ⅴ on day 60 to 75 and day 75 to 90. 2） On day 75 and 90,serum urea content in group Ⅴ was the highest,and urine urea content in group Ⅲ was the highest; on day 65 and 75,serum creatinine content was the highest,and on day 90,group Ⅳ had the highest value; on day 15,30 and 45,urine creatinine content was the highest in group Ⅴ; on day 45,serum uric acid content in group Ⅲ was the highest,and on day 75 and 90,group Ⅴhad the highest value; on day 15 and 30,urine uric acid content in group Ⅴ was the highest,and on day 75 and 90,group Ⅲ had the highest value. 3） No urolithiasis goat was found in groups Ⅰ and Ⅱ,and 3,4 and 5 urolithiasis goats were found in groups Ⅲ,Ⅳ and Ⅴ,respectively. In conclusion,DCAB value of150 mEq/kg DM is beneficial to maintain partial biochemical indices of serum and urine of Liaoning cashmere goats and prevent goats form urolithiasiss.
