Relative ratios of serum concentrations of selected fatty acids and carnitine metabolites in geriatric dogs (>7 yr) vs. mature adult dogs (≤7 yr) at baseline (initial) and after consuming control* or treatment foods for 194 days.

†The ratios are the average concentration of an analyte for dogs in the geriatric group divided by average concentration of the same analyte for dogs in the mature adult group.§Because there was no age by diet interaction, concentrations for dogs consuming different diets are combined across time.aThere was a significant effect of age on these ratios (P≤0.05).bThere was an effect of age on these ratios (P>0.05, P*,£, ¥, ¶,#,‡ See Table 1 for rest of key.

† 该比值为老年组犬各分析物的平均浓度与成熟成年组犬对应分析物平均浓度的比值。
§ 因未检测到年龄与日粮的交互效应，不同日粮饲喂组犬的浓度数据将按时间合并。
a 年龄对上述比值存在显著影响（P≤0.05）。
b 年龄对上述比值存在影响（P>0.05，P*,£, ¥, ¶,#,‡ 其余关键信息详见表1）
