摘　　要：以密码子使用频率为指导进行日粮氨基酸生物配比。在增加外源核苷酸的条件下 ,雏鸡的日增重明显增加。 34日龄对照组与实验组Ⅰ、Ⅱ、Ⅲ、Ⅳ的日增重分别为 (9.5 2± 0 .4 94 )、(10 .4 9± 0 .2 0 4 )、(10 .2 1± 0 .5 4 7)、(11.4 1± 0 .716 )和 (11.2 1± 0 .2 31) g。肝脏中总RNA含量分别为 (3996 .2± 16 1.5 7)、(44 39.4± 174 .96 )、(42 39.6± 91.12 )、(475 8.4±12 2 .93)、(486 4 .6± 172 .0 4 ) μg/g。结果表明 ,外源核苷酸在家禽体内能被利用 。Directed by the usage rate of tricodons on the messenger RNA nucleotide sequence,the biological formula of anino acids for chicken diet were designed.With the supplement of foreign nucleotide,the dialy body weight gams of contrast and experiment unit of chickens were (9.52±0.494)?(10.49±0.204)?(10.21±0.547)?(11.408±0.716)和(11.21±0.231) gram?respectivility.Total RNA contains in liver were (3996.2±161.57)?(4439.4±174.96)?(4239.6±91.12)?(4758.4±122.93)?(4864.6±172.04) μg/g.The results showed that foreign nucleotide can be used in chicken body.The daily body weight gains and RNA as well as DNA contains can be increased when the rate of amino acids tend to balance.
