Abstract

Three digestion and nitrogen metabolism trials were conducted using wether lambs fed rations containing urea as the source of non-protein nitrogen. The effect of diethylstilbestrol (DES) and diallylhexestrol (DAH) upon digestibility of dry matter, organic matter, crude protein (N x 6.25), and crude fiber, and their effect upon the retention of absorbed nitrogen were determined. The effect of these estrogenic compounds on blood glucose and urea N, ammonia N, and amino acid N also was determined.

Neither DES nor DAH significantly influenced nutrient digestibility. DES significantly increased the retention of absorbed nitrogen. In two of the trials this response was significant. DAH did not exert a significant effect upon the retention of absorbed nitrogen in any of the trials. Neither compound had a significant influence upon blood levels of amino acid N, urea N, ammonia N or glucose.
