摘  要：
为了证明复合植物精油改善仔猪饲料效率的机理。试验根据2×2析因设计,2个消化能水平(DE:14.27和13.37 MJ/kg DM)对应2个添加剂水平(复合植物精油:添加和不添加),采用内源指示剂-盐酸不溶灰分(AIA)法,研究了复合植物精油对仔猪养分和能量表观利用率的影响。选用35 d三元(杜×长×大)猪24头,随机分成4个处理,每个处理6个重复,每个重复1头。处理1(高能量)按NRC(2012)仔猪饲养标准配制;处理2在高能量日粮基础上添加复合植物精油600 mg/kg;处理3(低能量)消化能按高能量日粮减少0.84 MJ/kg DM,其他营养水平均同高能量日粮;处理4在低能量日粮基础上添加复合植物精油600 mg/kg。预试期7 d,正试期4 d。研究结果表明:与高能量水平日粮(DE 14.27 MJ/kg DM)相比,仔猪饲喂低能量日粮(DE 13.37 MJ/kg DM),显著提高了有机物质(P=0.040)、粗脂肪(P<0.000 1)、粗蛋白质(P=0.018)和能量(P=0.018)利用率,有提高干物质(P=0.059)和日粮消化能水平的趋势(P=0.061)。仔猪采食低能量水平日粮,赖氨酸(P=0.001)、甘氨酸(P=0.016)和组氨酸(P=0.082)表现消化率有所降低。添加复合植物精油显著提高了赖氨酸、蛋氨酸、精氨酸、亮氨酸、异亮氨酸、苯丙氨酸、苏氨酸、缬氨酸、天冬氨酸、丝氨酸、谷氨酸、甘氨酸、酪氨酸、脯氨酸,以及总EAA和总NEAA的表观消化率(P<0.05),组氨酸和丙氨酸差异不显著。复合植物精油可以用于改善仔猪氨基酸利用率,有利于氨基酸吸收。

摘  要：
Experiment using twenty-four 35-day-old weaned piglets(Duroc×Landrace×LargeYorkshire) that were randomly allocated to 4 treatments with 6 replicates in a 2×2 factorial de-sign was conducted to assess the effects of com-pound plant essential oil on the utilization rateof feed nutrients and energy of weaning piglets.The piglets were fed corn-soybean meal diets in high-energy(HE,the digestive energy measured was14.27 MJ/kg) and low-energy(LE,the digestive energy measured was 13.37 MJ/kg),or were supple-mented with 600 mg/kg essential oil extract in diets of HE and LE treatment.Apparent digestibility ofdiets was measured by the endogenous indicator of AIA there was an adjustment period of 7 d beforefaeces were collected daily for 4 d.Compared with HE diets,weaning piglets fed LE diets had signifi-cantly higher apparent digestibility of organic matter(P=0.040),ether extract(P<0.0001),crude pro-tein(P=0.018),energy(P=0.018),lysine(P=0.001),glycine(P=0.016),histidine(P=0.082).Addingcompound plant essential oil significantly improved(P<0.05) the apparent digestibility of amino acids(Lysine,methionine,arginine,leucine,isoleucine,phenylalanine,threonine,valine,aspartic acid,glu-tamic acid,glycine,serine,tyrosine and proline),total essential amino acid(TEAA) and total non-es-sential amino acid(TNEAA).Results of this study indicate that compound plant essential oil additionwas effective in improving nutrient digestibility in pigs fed a corn and soybean meal diet from diges-tive energy 13.37 MJ/kg to 14.27 MJ/kg.
