A rather long list of broad generalizations exist regarding milk replacers for calves. At least two more general statements should be added to that list. Most broad generalizations regarding milk replacers should be applied cautiously; and if young calves (less than 2 to 3 weeks) are to be fed milk substitutes, the products should be of high quality. Our primary goal in feeding baby calves should be health oriented--that is, not to pre-dispose to or cause diarrhea through diet. This means using milk-source ingredients in milk substitutes targeted for young calves. The preponderance of data presented in this article underscores that statement. Milk replacers containing nonmilk sources of major nutrients are better fed to older calves.
关于犊牛代乳品，存在一长串相当宽泛的概括性观点。至少还应在该列表中增加两条一般性陈述。关于代乳品的大多数宽泛概括都应谨慎应用；并且如果要给幼龄犊牛（不到2至3周龄）饲喂代乳品，产品应质量上乘。我们饲喂犊牛的主要目标应以健康为导向——也就是说，不要因饮食而 predispose 或导致腹泻。这意味着在针对幼龄犊牛的代乳品中使用奶源成分。本文所呈现的大量数据强调了这一观点。含有非奶源主要营养素来源的代乳品最好饲喂给大龄犊牛。 （注：“predispose”此处结合语境推测意思，但在准确翻译时最好能结合更多专业背景信息来精准表达其确切含义，目前翻译为“predispose”暂作一种模糊处理。）
