Mortality due to nephritis and uric acid diathesis was observed during the fall and winter in captive willow ptarmigan. The present study examined how feed protein concentration influences feed and water consumption, plasma uric acid concentration, and mortality due to nephritis and uric acid diathesis in captive willow ptarmigan. An increase in feed protein concentration from 14 to 24 resulted in reduced feed consumption and increased plasma uric acid concentration. Mortality due to nephritis and uric acid diathesis was not influenced by variations in feed protein concentration, but an admixture of 14 % grass meal to the diet reduced the incidence markedly.
在圈养柳雷鸟中,秋季和冬季观察到因肾炎和尿酸素质导致的死亡情况。本研究考察了饲料蛋白质浓度如何影响圈养柳雷鸟的采食量、饮水量、血浆尿酸浓度以及因肾炎和尿酸素质导致的死亡率。饲料蛋白质浓度从14%提高到24%会导致采食量减少和血浆尿酸浓度升高。因肾炎和尿酸素质导致的死亡率不受饲料蛋白质浓度变化的影响,但在日粮中添加14%的草粉可显著降低发病率。
