摘　　要：１０２４羽罗曼蛋鸡随机分４组，分别饲喂二氢吡啶添加量为０，１００，１５０，２００ｍｇ／ｋｇ的４种饲粮，结果表明：二氢吡啶可以显著地改进蛋鸡的产蛋性能，其中添加１５０ｍｇ／ｋｇ效果最佳，产蛋率提高了１１．０８％，料蛋比降低了１０．３６％．蛋重随日粮中二氢吡啶递增呈上升趋势．二氢吡啶使血清尿酸含量显著降低（ｐ＜０．０５）；二氢吡啶使血清Ｃａ浓度、Ｐ浓度下降（ｐ＜０．０５），具有降低破蛋和异常蛋的作用（ｐ＜０．０５）；二氢吡啶可促进浓蛋白和蛋黄的合成（ｐ＜０．０５），降低蛋黄中胆固醇的含量；添加二氢吡啶还显著地提高了脂肪酶活性（ｐ＜０．０５），降低了血清甘油三酯和总胆固醇含量（ｐ＜０．０１），降低腹脂率和肝脏中脂肪含量（ｐ＜０．０１），防止脂肪肝的发生；二氢吡啶还可以提高血清超氧化物岐化酶活力（ｐ＜０．０１），对血清ＧＰＴ与ＧＯＴ无明显影响，因而具有保护生物膜的作用．The experiment was conducted to study the effects of diludine on laying performance and egg quality in hens,and approach to the mechanism of the effects by determining indexes of egg and serum parameters 1024 ROM hens were divided into four groups, each of which included four replicates of 64 hens each, The treatment groups received the same basal diet supplemented with 0, 100, 150, 200 mg/kg diludine respectively for 80 d The results were as follows: Addition of diludine to diet improved hens laying performance, of which 150 mg/kg treatment was best, its rate of lay was increased by 11 08% ( p <0 01), egg mass conversion was decreased by 10 36% ( p <0 01) Egg weight were increased with the increasing of diludine added Diludine significantly dcereased the serum concentration of uric acid ( p <0 01); Adding diludine significantly decreased the serum Ca 2+ and inorganic phosphate content , and increased activity of alkine phosphatase (ALP) of serum ( p <0 05), so it had significant effects on reducing egg breakage ( p <0 05) and abnormality ( p <0 05); Diludine significantly increased the albumen height, Haugh value ( p <0 01), shell thickness and shell weight ( p <0 05), 150 and 200 mg/kg diludine also decreased total choleasterol in egg yolk ( p <0 05), but increased egg yolk weight ( p <0 05); In addition, Diludine could enhance the activity of lipase ( p <0 01), and decrease the content of triglyceride (TG3) ( p <0 01) and cholesterol (CHL) ( p <0 01) in serum, it reduced percentage of abdominal fat ( p <0 01) and liver fat content ( p <0 01), had ability to prevent hen from fattyliver Diludine significantly increased activity of SOD in serum ( p <0 01) when it was added to diet for more than 30 d However, no significant difference were found in activities of GPT and GOT of serum between the control and treated group, It was inferred that diludine could prevent membrane of cells from oxidation
