The Effect of Ageing on Nutrient Digestibility by Cats Fed Beef Tallow-, Sunflower Oil- or Olive Oil-Enriched Diets

摘要

Nutrient digestibility and absorption decline with age in several mammalian species. The aim of this study was to compare apparent fat di- gestibility of different dietary fats in young and se- nior cats. Three diets enriched with either beef tal- low (high in saturated fatty acids), olive oil (high in monounsaturated fatty acids) or sunflower oil (high in polyunsaturated fatty acids) were fed to 6 young (3.0±0.9y) and 6 senior (11.6±1.4y) cats at 300 kJ metabolisable energy/kg BW~0.75/d in a 3~*3 Latin square design.
