The present study aimed to evaluate the inflammatory response, oxidative status and fatty acid deposition in reproductive tissues of cats supplemented with the dried microalgae Schizochytrium spp. (Thraustochytriaceae) as a DHA source. Thirty-seven cats (males, n 21; females, n 16; 11·5 (sd 0·5) months of age) were divided by sex into five groups. Treatment diets contained algae biomass at 4·0, 8·0, 12·0 or 16·0 g/kg replacing poultry fat (n-6 source). Cats were fed the respective diet for 62 d and neutered on day 58. Blood samples were collected at the beginning of the experiment (day 1), before neutering (day 58) and 4 d after surgery (day 62) for analysis of inflammation and oxidative markers. Acute-phase protein levels were altered (P < 0·01) in the postoperative period, without any treatment effect (P > 0·05). PGE2 concentrations after surgery were reduced linearly (R2 0·8706; P = 0·002) with microalgal inclusion. Blood platelet count was reduced (P = 0·001) after the surgery regardless treatment, but it was higher in the DHA group compared with control (P < 0·001). The DHA deposition (testicles, R2 0·846; ovaries, R2 0·869) and the n-6:n-3 ratio (testicles, R2 0·859; ovaries, R2 0·955) in gonads had a pattern which fitted a quadratic model. DHA from Schizochytrium spp. modifies PGE2 response after the surgery in cats. The physiological roles of the DHA in the reproduction of cats were not investigated, but its gonadal deposition after supplementation was observed.

来自微藻裂殖壶菌属的 DHA。（Thraustochytriaceae）改变家猫的炎症反应和性腺脂质分布

本研究旨在评估补充干燥微藻的猫生殖组织中的炎症反应、氧化状态和脂肪酸沉积。裂殖壶菌属spp. (Thraustochytriaceae) 作为 DHA 来源。三十七只猫（雄性，n21; 女性，n16; 11·5 (sd0·5）月龄）按性别分为五组。处理日粮含有 4·0、8·0、12·0 或 16·0 g/kg 的藻类生物量，替代家禽脂肪（n-6 来源）。给猫喂食相应的饮食 62 天，并在第 58 天绝育。在实验开始时（第 1 天）、绝育前（第 58 天）和手术后 4 天（第 62 天）收集血样，用于分析炎症和氧化标记。急性期蛋白水平改变（磷< 0·01) 术后期间，无任何治疗效果(磷> 0·05)。PGE2手术后浓度线性降低（R20·8706;P =0·002) 含有微藻。血小板计数减少（P =0·001) 术后不管治疗，但DHA组高于对照组(磷 <0·001)。DHA 沉积（睾丸、R20·846; 卵巢，R20·869) 和n-6：n-3 比率（睾丸，R20·859；卵巢，R20·955) 在性腺中具有适合二次模型的模式。DHA 来自裂殖壶菌属spp. 修改 PGE2猫手术后的反应。没有研究 DHA 在猫繁殖中的生理作用，但观察到其补充后的性腺沉积。
