亚甲基水杨酸杆菌肽对热应激状态下马岗肉鹅生长性能和血液生化指标的影响
|
摘要
为研究亚甲基水杨酸杆菌肽(BMD)对热应激状态下肉鹅生长性能和血液生化指标的影响,选取45日龄的健康马岗肉鹅160只,按体重一致原则随机分成对照组和试验组,每组4个重复,每个重复20只鹅(公母各半)。对照组采食基础日粮,试验组日粮在基础日粮中添加100mg/kgBMD。试验期20d,试验期间温度为30~35℃。结果表明,马岗肉鹅的日均采食量、日均增重、腿肌率、胸肌率、SOD活性、T-AOC活性、T3水平、T4水平、TP浓度均表现为试验组显著高于对照组;料重比、腹脂率、LDH活性、GOT活性、GPT活性、AKP活性、MDA含量、BUN含量,试验组显著低于对照组;屠体率、半净膛率、全净膛率、GSH-PX活性,对照组与试验组间无显著差异。添加100mg/kgBMD可以改善热应激肉鹅血液生化指标,提高肉鹅屠宰性能,提高采食量,促进生长和提高饲料转化率。
The experiment aimed to study the effects of bacitracin methylene disalicylate (BMD) supplementation on growth performance and serum biochemical indices of Magang goose under heat stress.Total of 160 45-day-old Magang geese were randomized into control group and experimental group,with 4 replicates per group and 20 geese in each replicate.Geese in control group were fed with basal diet,while geese in experimental group were fed with basal diet supplemented with 100 mg/kg of BMD.The experiment lasted for 20 d,and the temperature was 30-35℃ during the study.The results showed that daily weight gain (DWG) and daily feed intake (DFI) of experimental group were significantly higher than those of control group.The ratio of DFI to DWG of experimental group was significantly lower than that of control group The leg muscle rate and breast muscle rate were notably higher in experimental group than those in control group.The percentage of abdominal fat was notably lower in experimental group than that in control group.There was no significant treatment effects on carcass rate,eviscerated rate and semieviscerated rate between experimental group and control group.The activities of serumLDH,GOT,GPT,AKP and contents of serum MDA and BUN in experimental group were significantly lower than those in control group.The activities of serum SOD,T-AOC and concentrations of serum TP,T3 and T4 of experimental group were significantly higher than those in control group.There was no treatment effect on the activity of GSH-PX between experimental group and control group.The results demonstrated that supplementation of BMD 100 mg/kg in the diet could improve the serum biochemical indices and slaughter performances of geese under heat stress,also increase feed intake,feed conversion rate and promoted growth performance.
