Results maidang rutong granules can promote the dilation and hyperplasia of acinus cavity and conduit in mammary gland , reduce the mammary interlobular fat connective tissue , significantly increase pituitary acidophil number and serum prolactin level , increase the milk volume of lactation rats and their offspring ' s body weight 结果麦当乳通颗粒可促进乳腺腺泡腔及导管扩大增生，减少乳腺小叶间脂肪结缔组织，明显增加垂体嗜酸性细胞数量和血清泌乳素水平，从而显著增加母大鼠的泌乳量，并显著提高其所喂养的仔鼠体重。
A single - factor experiment was designed to research the effect of nutrition level on body weight of multiparous sows during gestation through investigating the effect of gestation nutrition on the reproduction performance of multiparous sows in subsequent 3 parities and based on regression analysis of feed intake as well as lactation weight loss and reproduction performance during gestation 摘要采用单因子试验设计，通过对妊娠期不同营养水平连续3胎经产母猪生产的研究，建立妊娠期采食量与泌乳损失及繁殖性能等之间关系的回归方程，研究妊娠期不同营养水平对经产母猪体重变化的影响。
In conclusion , the rat mast cells belonging to mucosal mast cells without specific antigen . the level of cell immune is enhanced in non - lactating not in lactating period , although the whole immune level is great high in lactating period . . the immune of mammary gland may be a independence system . the immune properties and immune level obviously varied in physiological cycle 由此可知，在无特定抗原刺激条件下，大鼠乳腺肥大细胞是黏膜型肥大细胞；静止期乳腺的细胞免疫比泌乳期高；乳腺免疫具有相对独立性；泌乳期乳腺免疫状态高于静止期；乳腺体液免疫没有随生理时期而发生变化。
