A brief review of the status of arachidonic acid as an essential dietary nutrient for cats is presented. The reproductive performance of male and female cats given a purified diet containing only partially hydrogenated vegetable oil as the fat source from weaning was investigated. Male kittens did not require a supplemental source of arachidonate for normal body weight gain and successful reproduction. Female kittens given the same diet also appeared to grow normally, came into oestrus and conceived, but produced only a limited number of viable litters. Subsequent supplementation of these queens with arachidonic acid did not result in the birth of viable kittens. It is suggested that completion of a normal pregnancy by queens given a diet based on partially hydrogenated oil for protracted periods may require fatty acids in addition to arachidonate.
本文简要回顾了花生四烯酸作为猫必需膳食营养素的现状。研究了从断奶开始就食用仅含有部分氢化植物油作为脂肪来源的纯化日粮的雄性和雌性猫的繁殖性能。雄性小猫正常体重增加和成功繁殖不需要补充花生四烯酸来源。食用相同日粮的雌性小猫似乎也正常生长、发情并受孕，但只产下了数量有限的存活幼崽。随后给这些母猫补充花生四烯酸并没有导致存活小猫的出生。有人认为，长期食用基于部分氢化油的日粮的母猫完成正常妊娠可能除了花生四烯酸外还需要脂肪酸。
