摘  要:本试验旨在研究α-半乳糖苷酶和木聚糖酶对断奶仔猪生长性能和消化性能的影响。选用135头平均体重为(7.4±0.8)kg的杜×长×大三元杂交断奶仔猪,设9个组,每组3个重复,每个重复5头猪,采用3×3两因子完全交叉试验设计,设3个α-半乳糖苷酶水平(0、0.008%和0.012%)和3个木聚糖酶水平(0、0.008%和0.012%)。试验期为28d,分为前期(1~14d)和后期(15~28d)2个阶段。试验结果表明:1)添加α-半乳糖苷酶和木聚糖酶对断奶仔猪前期和全期的平均日增重、料重比和腹泻率有显著影响(P<0.05);对断奶仔猪后期的平均日增重、平均日采食量和料重比有显著影响(P<0.05);其中添加0.008%的α-半乳糖苷酶和0.008%的木聚糖酶可显著提高断奶仔猪的平均日增重和平均日采食量,显著降低料重比和腹泻率(P<0.05);2)添加α-半乳糖苷酶和木聚糖酶可以提高断奶仔猪各种养分的消化率,其中粗蛋白质、粗脂肪和粗纤维的消化率达到了显著效果(P<0.05)。由结果可知,α-半乳糖苷酶和木聚糖酶可一定程度上提高断奶仔猪生长性能和消化性能,以添加0.008%α-半乳糖苷酶和0.008%木聚糖酶的效果最好,且两者存在互作效应。In order to investigate the effects of a-galactosidase and xylanase on growth performance and digestive performance in weaned piglets, a 3 × 3 cross-over design trial with two factors was conducted and 135 healthy Duroc x Landrace × York- shire crossbred weaned piglets with average weight of (7.4 ± 0.8) kg were randomly assigned to 9 groups (3 replicates per group and 5 piglets per replicate). Supplemental levels of a-galactosidase were 0, 0. 008% and 0. 012%, respectively, and supplemental levels of xylanase were 0, 0. 008% and 0. 012%, respectively. The experiment lasted for 28 d, including early period (1-14 d) and later period (15-28 d). The results showed as follows: 1) a-galactosidase and xylanase had significant effects on average daily gain (ADG), F/G and diarrhea rates during early period and the whole period (P〈0.05), and had significant effects on ADG, average daily feed intake (ADFI) and F/G during later period (P〈0.05); supplementation with 0. 008% a-galactosidase and 0. 008% xylanase simultaneously significantly increased ADG and ADFI and decreased F/G and diarrhea ratio (P〈0.05) ; 2) a-galactosidase and xylanase could increase the digestibility of various nutrients, in which the digestibility of crude protein, crude fat and crude fiber had significant effects (P〈0.05). In conclusion, a-galactosidase and xylanaseon could improve the growth performance and digestive performance of weaned piglets to some degree, and supplementation with 0. 008% a-galactosidase and 0. 008% xylanase simultaneously was the best, and their interaction on growth performance and digestibility performance was found.
