【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(P0.000 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(P0.05),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。
[Abstract]:In order to prove the mechanism of compound plant essential oil to improve feed efficiency of piglets. According to the 2 脳 2 factorial design, two digestible energy levels (DE:14.27 and 13.37 MJ/kg DM) corresponded to two additive levels (compound essential oil: added or not), and the endogenous indicator, hydrochloric acid insoluble ash (AIA) method, was used. The effect of compound plant essential oil on apparent utilization of nutrients and energy in piglets was studied. Twenty-four pigs were randomly divided into 4 treatments with 6 replicates in each treatment and 1 in each. Treatment 1 (high energy) was prepared according to NRC _ (2012) standard for piglets, and treatment 2 was supplemented with compound plant essential oil for 600 mg/kg; on a high-energy diet. Other nutrient levels of treatment 3 (low energy) reduced by 0. 84 MJ/kg DM, were the same as those of high energy diet, and treatment 4 was supplemented with compound plant essential oil for 600 mg/kg. on a low energy diet. The pretest period was 7 days and the positive test period was 4 days. The results showed that compared with high energy level diet (DE 14.27 MJ/kg DM), low energy diet (DE 13.37 MJ/kg DM),) significantly increased organic matter (P0. 040) and crude fat (P0. 000 1). The utilization of crude protein (P0. 018) and energy (P0. 018) had a tendency to increase dry matter (P0. 059) and dietary digestibility energy level (P0. 061). The digestibility of lysine (P0. 001), glycine (P0. 016) and histidine (P0. 082) was decreased. The addition of compound essential oils significantly increased lysine, methionine, arginine, leucine, isoleucine, phenylalanine, threonine, valine, aspartic acid, serine, glutamate, glycine, tyrosine, proline, The apparent digestibility of total EAA and total NEAA (P0.05) showed no significant difference between histidine and alanine. Compound plant essential oil can be used to improve amino acid utilization and amino acid absorption in piglets.
