STUDIES ON MILK SUBSTITUTESⅣ. The effect of supplementing Milk Substitute 5410 with cod liver oil, thiamin or yeast on the growth of rats / 营养学报

ABSTRACT

In a previous communication we have reported that the nutritive value of Milk Substitute 5410 is comparable to that of a cow's milk diet, as measured by the growth of rats, despite its low vitamin A and thiamin contents. In the present investigation, the vitamin A or thiamin content of this Substitute was raised up to the level of the requirement of infants The vitamin A was furnished by cod liver oil, and thiamin was supplied in the form thiamin hydrochloride or yeast. Weanling rats of mixed sexes were used. After 16 weeks on diet, it was found that the male rats were 14-17% heavier in body weight and 4.4-5,8% longer in body length than the unsupplemented controls. These differences were maintained till the end of the experiment when the animals were practically fully grown. The total feed consumption and feed efficiency of the supplemented groups were higher than those of the control, especially in case of the male rats.
