The objective of this study was to evaluate the effects of the microalgae Schizochytrium sp., as a dietary source of docosahexaenoic acid (DHA), on diet palatability, coefficients of total tract apparent digestibility (CTTAD) of nutrients and metabolizable energy (ME), blood variables and indicators of immunity in dogs. We also evaluated oxidative stability. Two diets containing 0 and 0.4% of microalgae Schizochytrium sp. were evaluated in three experiments. On Experiment I the palatability of diets containing 0% versus 0.4% microalgae was compared. In Experiment II test diets were offered for 30 days to determine digestibility, fecal characteristics, and blood parameters. In Experiment III, the oxidative stability of diets containing microalgae versus anchovy oil was evaluated. There was a higher intake ratio of the diet containing microalgae (p < .05). The ME and CTTAD of nutrients increased (p < .05), except for ether extract after acid hydrolysis, with the inclusion of the microalgae in diet. The amount of monocytes and phagocytic granulocytes was higher (p < .05) in dogs fed 0.4% microalgae. There was greater oxidative stability for the sample containing microalgae. The addition of 0.4% microalgae presented high palatability, increased phagocytic cell numbers, and demonstrated oxidative stability superior to anchovy oil.

微藻裂殖藻 二十二碳六烯酸（DHA）的来源：对狗的饮食消化率，氧化和适口性以及免疫力和炎性指数的影响。

这项研究的目的是评估作为饮食来源二十二碳六烯酸（DHA）的微藻Schizochytrium sp。对饮食适口性，营养成分的总表观消化率（CTTAD）和代谢能（ME）的影响，犬的血液变量和免疫指标。我们还评估了氧化稳定性。两种饮食中分别含有0和0.4％的微藻Schizochytrium sp。在三个实验中进行了评估。在实验一中，比较了含0％和0.4％微藻的日粮的适口性。在实验II中，提供30天的饮食来确定消化率，粪便特性和血液参数。在实验Ⅲ中，评估了含微藻类和versus鱼油的日粮的氧化稳定性。含微藻饮食的摄入比例更高（p <.05）。营养物质的ME和CTTAD增加（p <.05），除了酸水解后的乙醚提取物外，还包括饮食中的微藻类。在饲喂0.4％微藻的狗中，单核细胞和吞噬性粒细胞的数量更高（p <.05）。含有微藻的样品具有更大的氧化稳定性。添加0.4％的微藻表现出较高的适口性，增加吞噬细胞的数量，并证明其氧化稳定性优于cho鱼油。含有微藻的样品具有更大的氧化稳定性。添加0.4％的微藻表现出较高的适口性，增加吞噬细胞的数量，并证明其氧化稳定性优于cho鱼油。含有微藻的样品具有更大的氧化稳定性。添加0.4％的微藻表现出较高的适口性，增加吞噬细胞的数量，并证明其氧化稳定性优于cho鱼油。
