Adoption of a plant-based diet is a popular lifestyle choice for many owners of canine companion animals. Increasingly, owners would like to feed their canine companions a similar diet. A plant-based dietary pattern has been reported to be associated with some micronutrient deficiencies. Complete dog foods are, by definition, supposed to be nutritionally replete in all macro- and micronutrients. Few studies have reported a full nutritional analysis of complete, dry plant- versus meat-based dog foods.
31 dry commercially available dog foods (n = 19 meat-based, n = 6 veterinary and n = 6 plant-based) were analysed for total protein content and individual amino acids, fatty acids, major and trace elements, vitamin D and all B-vitamins.
Nutritional composition of meat and plant-based foods were nutritionally similar, except for iodine and B-vitamins, which were lower in plant-based foods. The majority (66%) of veterinary diets with lower total protein by design, were also deficient in one or more essential amino acids. Isolated instances of non-compliance to nutritional guidelines were observed across all food-groups. Of the tested nutrients 55%, 16%, 24% and 100% of foods met all amino acid, mineral, B-vitamin, and vitamin D guidelines, respectively.
Adopting a plant-based dietary pattern for your companion canine can provide nutritional adequacy with respect to the majority of macro- and micronutrients, with the exception of iodine and B-vitamins, which could easily be supplemented. Veterinary-renal diets, purposely low in crude protein, often have less than optimal essential amino acid composition. These data provide important new information for owners of companion canines being fed plant-based or veterinary diets.
采用植物性饮食是许多犬类伴侣动物主人流行的生活方式选择。越来越多的主人希望给他们的犬类伴侣喂食类似的饮食。据报道，植物性饮食模式与一些微量营养素缺乏有关。根据定义，全价犬粮应该在所有宏量和微量营养素方面营养充足。很少有研究报告对全价、干制的植物性与肉类犬粮进行全面的营养分析。
对31种市售干犬粮（n = 19种肉类、n = 6种兽医专用粮和n = 6种植物性粮）进行总蛋白含量以及单个氨基酸、脂肪酸、常量和微量元素、维生素D以及所有B族维生素的分析。
肉类和植物性食品的营养成分在营养方面相似，但碘和B族维生素除外，植物性食品中的含量较低。大多数（66%）设计上总蛋白含量较低的兽医专用粮也缺乏一种或多种必需氨基酸。在所有食物组中都观察到了不符合营养指南的个别情况。在测试的营养素中，分别有55%、16%、24%和100%的食品符合所有氨基酸、矿物质、B族维生素和维生素D指南。
为您的伴侣犬采用植物性饮食模式在大多数宏量和微量营养素方面可以提供充足的营养，但碘和B族维生素除外，它们可以很容易地进行补充。兽医肾脏专用粮，粗蛋白含量特意较低，其必需氨基酸组成往往不太理想。这些数据为喂食植物性或兽医专用粮的伴侣犬主人提供了重要的新信息。
