title: [Effect of a ration with a varying amount of fat and protein of plant and synthetic origin on some indices of ruminal content and of the blood in lactating sheep].
abstract: The pH value of the rumen content in lactating ewes given sunflower expeller was 7.10, and that in ewes given urea was 6.70. The amount of ammonia in the rumen of ewes fed expeller was at a dependable lower level than the amount of ammonia with ewes fed urea. In animals fed expeller with the ration the blood sugar, protein, and lipids were higher, while acetone, beta-oxibutyric acid, and cholesterin dropped. In urea feeding, the levels of acetone, betaoxibutyric acid, and cholesterin rose, while blood sugar, protein, and lipids were lower. The Ca, P, Na, K, and Fe contents as well as the activity of the SGOT and SGPT enzymes in the blood of lactating ewes did not change essentially except for the amounts of Mg and Cu.
