In four trials with growing cattle we observed effects of 1,3-butanediol on rumen fermentation end products, blood components, growth rates, feed efficiency, and body composition. Diets A and C contained 80% grain: 20% alfalfa pellets and 40% grain: 60% alfalfa pellets; in diets B and D, 1,3-butanediol replaced 4% of diets A and C. Feeding 4% 1,3-butanediol caused no significant differences in rumen pH, volatile fatty acid ratios, blood glucose, or blood ketones. Cattle fed 4% 1,3-butanediol had rates of gain and feed efficiency equivalent to and often better than cattle fed the same diet without butanediol. Body composition was not affected by feeding 4% 1,3-butanediol. Results indicate 4% 1,3-butanediol can be fed to cattle without adverse physiological effects and may improve performance. When 6% or more 1,3-butanediol was fed, blood ketones were elevated considerably, animals were hyperactive, gained less weight, and feed efficiency was lower.
在四项针对生长牛的试验中，我们观察了1,3 - 丁二醇对瘤胃发酵终产物、血液成分、生长速度、饲料效率和身体组成的影响。日粮A和C分别含有80%谷物:20%苜蓿颗粒以及40%谷物:60%苜蓿颗粒；在日粮B和D中，1,3 - 丁二醇替代了日粮A和C的4%。饲喂4%的1,3 - 丁二醇对瘤胃pH值、挥发性脂肪酸比例、血糖或血酮没有显著差异。饲喂4% 1,3 - 丁二醇的牛的增重速度和饲料效率与饲喂不含丁二醇的相同日粮的牛相当，且往往更好。身体组成不受饲喂4% 1,3 - 丁二醇的影响。结果表明，4%的1,3 - 丁二醇可以喂给牛而不会产生不良生理影响，并且可能改善性能。当饲喂6%或更多的1,3 - 丁二醇时，血酮显著升高，动物多动，体重增加较少，饲料效率较低。
