Digestibility, fecal characteristics, and levels of glucose and urea in the plasma were determined in 8 dogs that received 2 different dog foods once or 3 times daily. One dog food (A) was 5 times more expensive than the other (B). Fecal pH and consistency, digestibility of dry matter (DM), organic matter (OM), crude protein (CP), and crude fiber (CF) were determined. Blood samples were taken from 30 min before to 60 min after a meal. Digestibilities of DM, OM, and CP, and fecal consistency were higher, and daily fecal excretion and fecal pH were lower when dogs were fed food A (P < 0.001). The feeding schedule had no effect on plasma glucose and urea. Neither feeding X frequency nor food 3 frequency interactions was significant for the parameters studied.
对8只犬进行了研究，这些犬每天喂食1次或3次两种不同的狗粮，测定了它们的消化率、粪便特征以及血浆中葡萄糖和尿素的水平。一种狗粮（A）的价格是另一种（B）的5倍。测定了粪便pH值和稠度、干物质（DM）、有机物（OM）、粗蛋白（CP）和粗纤维（CF）的消化率。在进食前30分钟至进食后60分钟采集血样。当犬喂食狗粮A时，DM、OM和CP的消化率以及粪便稠度较高，每日粪便排泄量和粪便pH值较低（P < 0.001）。喂食时间表对血浆葡萄糖和尿素没有影响。对于所研究的参数，喂食次数与食物种类之间的交互作用均不显著。
