摘 要：
为研究桑叶作为饲料来源,其不同添加水平对母猪生产性能、血液生理生化和免疫指标的影响。试验选择胎次、配种时间相近的长白×大约克经产母猪40头,随机分为4组(Ⅰ、Ⅱ、Ⅲ、Ⅳ组),对照组饲喂不同阶段的基础日粮;母猪妊娠期在妊娠母猪基础日粮中添加5%(Ⅰ组),10%(Ⅱ组),15%(Ⅲ组)的桑叶粉。结果表明:Ⅱ组母猪总产数和活产数较对照组分别提高了8.5%和5.5%,差异显著(P<0.05);单核细胞比率、淋巴细胞数、单核细胞都是随着饲喂桑叶粉比例的增加而降低,Ⅰ组、对照组差异显著(P<0.05);红细胞平均体积、平均血红蛋白量、平均血红蛋白浓度和血小板等4项指标大致呈现出随着饲喂桑叶粉比例的增加而增大的趋势,Ⅲ组较对照组显著升高(P<0.05)。桑叶饲料对母猪猪瘟、猪圆环病毒2型抗体水平无负面影响。为桑叶作为饲料开发及进一步利用提供了参考。

摘 要：
The purpose of this study was to investigate the effects of different levels of mulberry leaves on the production performance, blood physiological and biochemical, and immune indexes of sows. Thisexperiment choose the similar parity and breeding time of Landrace×York sows 40 heads, they were randomly divided into 4 groups(group Ⅰ, group Ⅱ, group Ⅲ and control group), the control group wasfed with basal diet; and 5%(group Ⅰ), 10%(group Ⅱ) and 15%(group Ⅲ) mulberry leaves powder wereadded to the basal diet during the gestation period. The results showed that compared with the controlgroup, the total number of sows and the number of live births in the group Ⅱ increased by 8.5% and5.5% respectively. The ratio of monocytes, lymphocytes and monocytes decreased as the proportion ofmulberry leaves increased,there was significant difference between group Ⅰ and control group(P<0.05); the four indexes, such as the average volume of red blood cell, the average hemoglobin quantity,the average hemoglobin concentration and the blood platelet, generally showed the trend of increasingwith the proportion of mulberry leaf powder, group Ⅲ was significantly higher than control group(P<0.05). Mulberry leaves feed had no negative ef-fect on the antibody level of hog cholera virusand porcine circovirus type 2. It provides refer-ence for the development and further utilizationof mulberry leaves as feed.
