薄荷提取物对肥育猪生产性能和生化指标的影响

Effects of Mentha Haplocalyx.Briq Extracts Performance and Content of some Routine Index in Serum of Finishing pigs

研究日粮中添加薄荷提取物对肥育猪采食量、体型及血液生化指标的影响。试验采用单因子设计,选取体重70 kg左右的杜大长三元杂交猪270头,随机分成5组,每组3个重复,每个重复18头。每组在基础日粮上分别添加薄荷提取物0 mg/kg、6.25 mg/kg、12.5mg/kg、25 mg/kg5、0 mg/kg。结果表明,试验Ⅱ、Ⅲ、Ⅳ组添加薄荷提取物显著地减少肥育猪的平均日采食量(P<0.01),分别比对照组下降11.96%(P<0.01)、15.03%(P<0.01)和9%(P<0.01)。除试验I组外,其它三组的体型评分均优于对照组,且分别比对照组提高11.49%(P<0.01)、14.28%(P<0.01)和3.18%(P<0.05)。各试验组血清生化指标均与对照组差异不显著(P>0.05)。

The experiment was conducted to determine the effect of different levels Mentha haplocalyx. Briq extracts on growth performance ,feed intake,and bodyshape to discuss the optimum addition level of Mentha haplocalyx. Briq Extracts in finishing pigs＇ diet. Two hundred and seventy finishing pigs （ about 70±3 kg body weight） were divided into five groups randomly, with three replications per group and 18 pigs per replication. Pigs of the control group were fed a basal diet and the trial groups fed on basal diet supplemented with 6.25mg/kg 12.5 mg/kg, 25 mg/kg, 50 mg/kg,Mentha extracts, respectively. The results of feeding trial indicted that Mentha haplocalyx. Briq extracts reduced significantly feed intake. 12.5 mg/kg, 25 mg/kg, 50 mg/kg of Mentha haplocalyx. Briq Extracts could significantly reduce feed intake by 11.96 % （ P 〈 0.01 ）,15.03%（ P 〈 0.01 ） and 9%（ P〈 0.01 ）. Studies showed that 12.5 mg/kg, 25 rng/kg, 50 mg/kg of Mentha haplocalyx. Briq extracts significantly improved the bodyshape of finishing pigs by 11. 49 %（p〈0. 01） ,14. 28%（ P 〈 0.01 ） and 3.18%（ P 〈 0.05 ） in contrast to the control group 6.25 mg/kg Mentha Extracts had no significantly change. In contrast to control, Mentha haplocalyx. Briq Extracts had no significant effects oncontent of some routine index in serum of finishing pigs.
