A total of 15 primiparous sows (Landrace × Yorkshire) and their litters were used in the current study to evaluate the efficacy of cellulase supplementation on the production performance of sows and piglets. Pigs were randomly allocated into one of three treatments with five replicates per treatment. The dietary treatments were as follows: (i) CON (corn-soybean meal-based control); (ii) EZ1 (CON + 0.05% cellulase); and (iii) EZ2 (CON + 0.10% cellulase). The supplementation of cellulase had no effect (P > 0.05) on body weight and feed intake of lactating sows. At weaning, back fat thickness loss decreased (P = 0.04) linearly in EZ1 and EZ2 treatments. The average daily gain (ADG) of piglets increased (linear P = 0.06, quadratic P = 0.04)) during days 14 to 21 as well as at days 21 to 25 (linear P = 0.03 and quadratic P = 0.01) with the increase in the level of supplemented enzyme. Dry matter and nitrogen digestibility increased (linear P = 0.01) in lactating sows fed EZ1 and EZ2 diet compared with CON. In conclusion, it is suggested that cellulase supplementation to corn-soybean meal based diet exerts beneficial effects to sows in reducing their back fat thickness loss at weaning and also helps to improve nutrient digestibility. It also helped to improve the ADG of piglets.
本研究共使用了15头初产母猪（长白猪×大白猪）及其仔猪，以评估添加纤维素酶对母猪和仔猪生产性能的影响。将猪随机分为三个处理组之一，每个处理组有五个重复。日粮处理如下：（i）CON（以玉米-豆粕为基础的对照组）；（ii）EZ1（CON + 0.05%纤维素酶）；（iii）EZ2（CON + 0.10%纤维素酶）。添加纤维素酶对泌乳母猪的体重和采食量没有影响（P > 0.05）。在断奶时，EZ1和EZ2处理组的背膘厚度损失呈线性下降（P = 0.04）。随着添加酶水平的增加，仔猪在第14至21天以及第21至25天的平均日增重（ADG）增加（线性P = 0.06，二次项P = 0.04））（线性P = 0.03，二次项P = 0.01）。与CON组相比，饲喂EZ1和EZ2日粮的泌乳母猪的干物质和氮消化率增加（线性P = 0.01）。总之，建议在以玉米-豆粕为基础的日粮中添加纤维素酶对母猪有有益影响，可减少其断奶时的背膘厚度损失，并有助于提高养分消化率。它还有助于提高仔猪的ADG。
