These studies have been designed to test whether 1,3-butanediol (BD) alleviates milk fat depression in lactating cows, to observe physiological changes in blood and rumen constituents when BD is fed to cows or growing cattle, and to test the effects of BD on growth rates and feed efficiency in growing cattle. In trials with lactating cows, milk fat percentage and total fat production were higher for cows fed BD than for controls. Feeding BD to either cows or growing cattle had no consistent effect on rumen pH or relative concentrations of rumen volatile fatty acids. 1,3-Butanediol feeding had little effect on blood glucose concentrations. Feeding more than 4% BD in diets sometimes caused increased concentrations of blood ketones. In trials where growing cattle were fed 4% BD, rates of gain and feed efficiency were at least as good as and often better than those of cattle fed the same diets without BD. Body composition was not significantly affected. 1,3-Butanediol can be utilized effectively as an energy source for cattle and causes no obvious problems with 4% in diets.

1,3-Butanediol-1,3-dioctanoate (BDDO), a synthetic source of energy, has been shown to be equal to corn oil when fed to chicks recovering from moderate and severe Newcastle disease virus infections. Body weight increments of chicks fed diets containing 10% BDDO were equal to or greater than those of chicks fed 10% corn oil, both with restricted feeding regimens. Kilocalories of metabolizable energy required to produce 100 g of body weight increment over a basal group was used as a means of quantitating energy demand. BDDO was comparable to corn oil as an energy source with no adverse effects. Liver/body weight ratios were greater in the BDDO-fed chicks. Circadian rhythmicity of liver size and liver glycogen content was demonstrated. Chicks fed BDDO had total liver glycogen content threefold that of the corn oil controls, which was attributed to stimulation of insulin secretion. Catch-up growth in the chick following the growth depression of disease appears to be as well facilitated by a synthetic source as by a natural one.
