摘要
Abstract
The study was conducted to investigate the effect of nucleotide diet supplementation on growth performance and nutrient apparent digestibility and some blood parameters,and to determine the best dose of nucleotide additive in diets supplementation.240 21-day-old piglets (Duroc× Landrace× Large white) having similar weight were allotted to 4 groups (control group,nucleotide group Ⅰ,lⅡ,Ⅲ) after weaning,with 6 repetition in each group and 10 piglets for each repetition.All weaning piglets had access to 4 standardized diet supplemented with 0.0％,0.05％,0.1％,0.2％ of nucleotide additive respectively during the 42 days' trial.The average daily growth of piglets in three treatment groups showed a significant increase than the control group(P＜0.05).The digestibility of crude fat was apparently higher in three treatment groups than control group(P＜0.05),nevertheless the digestibility of phosphor and dry matter and gross energy was higher in nucleotide group Ⅲ (P＜0.05).The piglets in nucleotide group Ⅱ showed a higher white blood cell and hematocrit determination level than the control group(P＜0.05).The piglets in nucleotide groups Ⅰ and Ⅱ and lⅢ showed a higher creatinine and blood urea nitrogen level than the con-trol group(P＜0.05).Aspartate transaminase level in nucleotide group Ⅰ was higher than the control group(P＜0.05).In conclusion,the results suggested that the piglets fed with 0.2％ of nucleotide additive showed better growth performance and higher nutrient utilization.关键词
