This study was conducted to evaluate effects of dietary multi-carbohydrases (MCS) in a lactating sow diet on productive performance and immune responses of sows and their piglets. A total of 12 sows (218.37 ± 5.5 kg BW; 2 parity) were randomly assigned to 2 dietary treatments: a diet based on corn-soybean meal (CON) and CON with 0.01% MCS. The MCS contained xylanase (2,700 units/g), β-glucanase (700 units/g), and cellulase (800 units/g). Sows were fed the dietary treatments for 28 days (weaning) after farrowing. Blood samples were collected from sows on d 0, 3, and 7 after farrowing and randomly selected 2 nursing piglets in each sow on d 3, 7, and 14 after birth. Measurements were productive performance of sows, frequency of diarrhea of piglets, and immune responses of sows and their piglets. Sows fed MCS had lower ( < 0.05) their body weight change than those fed CON. Piglets from sows fed MCS had higher ( < 0.05) average weight gain and body weight at weaning day and lower ( < 0.10) frequency of diarrhea than those from sows fed CON. Sows fed MCS had lower number of white blood cells (WBC) on d 3 ( < 0.05) and TGF-β1 on d 7 ( < 0.10) during lactation than those fed CON. Similarly, piglets from sows fed MCS had also lower ( < 0.05) number of WBC on d 3 and d 7 and TGF-β1 and C-reactive protein on d 7 during lactation than those from sows fed CON. In addition, piglets from sows fed MCS had higher ( < 0.10) immunoglobulin G and M on d 7 during lactation those from sows fed CON. In conclusion, addition of dietary MCS in the lactating sow diet based on corn and soybean meal improved productive performance of sows and their litters and modulated their immune responses.
本研究旨在评估泌乳母猪日粮中添加复合碳水化合物酶（MCS）对母猪及其仔猪生产性能和免疫反应的影响。总共12头母猪（体重218.37±5.5千克；二胎）被随机分为2种日粮处理组：基于玉米-豆粕的日粮（CON）和添加0.01% MCS的CON日粮。MCS包含木聚糖酶（2700单位/克）、β-葡聚糖酶（700单位/克）和纤维素酶（800单位/克）。母猪在分娩后接受日粮处理28天（至断奶）。在分娩后第0、3和7天采集母猪血液样本，并在出生后第3、7和14天从每头母猪中随机选取2头哺乳仔猪。测量指标包括母猪的生产性能、仔猪腹泻频率以及母猪及其仔猪的免疫反应。饲喂MCS的母猪体重变化低于（<0.05）饲喂CON的母猪。饲喂MCS的母猪所产仔猪在断奶日的平均体重增加和体重更高（<0.05），腹泻频率更低（<0.10）。与饲喂CON的母猪相比，饲喂MCS的母猪在泌乳期第3天白细胞（WBC）数量更低（<0.05），第7天转化生长因子-β1（TGF-β1）更低（<0.10）。同样，与饲喂CON的母猪所产仔猪相比，饲喂MCS的母猪所产仔猪在泌乳期第3天和第7天的WBC数量也更低（<0.05），第7天的TGF-β1和C反应蛋白也更低。此外，与饲喂CON的母猪所产仔猪相比，饲喂MCS的母猪所产仔猪在泌乳期第7天的免疫球蛋白G和M更高（<0.10）。总之，在基于玉米和豆粕的泌乳母猪日粮中添加MCS可提高母猪及其仔猪的生产性能，并调节其免疫反应。
