The purpose of this experiment is to expand the feed of growing sika deer and to explore the effects on growing sika deer of the spent mushroom substrate of (SMS-MP). Twelve immature female growing sika deer were randomly assigned to four groups. The ratios of SMS-MP to replace concentration supplements were 0%, 10%, 20%, and 30%, respectively, and the growth performance, feed intake and apparent digestibility, serum biochemical indexes, blood physiological indexes, serum immune globulin and plasma amino acid of growing sika deer were measured. The results of the current study confirmed the applicability of SMS-MP as a feed ingredient in growing sika deer diets. There was no significant change in growth performance and hematology of growing sika deer when the concentrate supplement was replaced with 10-20% SMS-MP. However, replacing 30% of concentrate supplements with SMS-MP in the growing sika deer diet resulted in significantly decreased Hb and HCT levels. It can be concluded that, as a waste resource, adding a small amount of SMS-MP has no significant effect on the growth of sika deer, and at the same time can reduce the consumption of concentrate supplements, thereby improving the economic benefits of sika deer breeding.
本实验的目的是扩大梅花鹿生长阶段的饲料来源，并探究平菇菌糠（SMS-MP）对梅花鹿生长的影响。将12只未成年雌性梅花鹿随机分为四组。SMS-MP替代浓缩料补充剂的比例分别为0%、10%、20%和30%，并测定梅花鹿的生长性能、采食量和表观消化率、血清生化指标、血液生理指标、血清免疫球蛋白和血浆氨基酸。本研究结果证实了SMS-MP作为梅花鹿生长阶段日粮中饲料原料的适用性。当用10%-20%的SMS-MP替代浓缩料补充剂时，梅花鹿的生长性能和血液学指标没有显著变化。然而，在梅花鹿日粮中用30%的SMS-MP替代浓缩料补充剂会导致血红蛋白（Hb）和红细胞压积（HCT）水平显著下降。可以得出结论，作为一种废弃资源，添加少量的SMS-MP对梅花鹿的生长没有显著影响，同时可以减少浓缩料补充剂的消耗，从而提高梅花鹿养殖的经济效益。
