Ruminal synthesis and biohydrogenation of fatty acids in dairy cows were determined by sampling duodenal digesta through T-cannulas. Fatty acid digestibility in the total tract also was measured. Five diets (concentrate:alfalfa hay:alfalfa haylage:corn silage, 2:1:1:1, DM) in a 5 x 5 Latin square contained either no added fat; 3 or 6% added calcium soap; or(More)
Ruminal degradation, synthesis, and biohydrogenation of fatty acids were examined in vitro. Diets were incubated with ruminal contents, and changes of fatty acids were measured. Two fat supplements, a calcium soap and an animal-vegetable blend, were included in diets at various levels. Addition to diets of acetate and isoacids (collective term for certain(More)
Five lactating Holstein cows with ruminal and duodenal cannulas were used in a 5 x 5 Latin square to determine the site of mineral absorption and effects of sources and amount of dietary fat on apparent absorption. Cows were fed (DM, 17.4 +/- .8 kg/d) chopped alfalfa hay, alfalfa haylage, corn silage, and concentrate at 1:1:1:2 (DM) at 12-h intervals.(More)
The pathogenesis of angiostrongyliasis, resulting from Angiostrongylus cantonensis invasion of the human central nervous system, remains elusive. Anthelmintics are usually used to kill worms, although dead worms in the brain may cause severe inflammation which will lead to central nervous system damage. Therefore, combination therapy with anthelmintics and(More)
Effects of two levels of Ca soap or animal-vegetable fat on digestion of fiber and N and on microbial protein synthesis were studied in five ruminally and duodenally cannulated lactating cows in a 5 x 5 Latin square. Fat was added at 0, 2.5%, or 5% of dietary DM, which consisted of a 60:40 forage:concentrate mix. Treatment did not influence DMI, duodenal OM(More)
Measurement of serum digoxin concentration is recommended as a routine in patients undergoing digoxin therapy because its therapeutic range is narrow. The presence of a high concentration of digoxin-like immunoreactive substances(DLIS) in human serum have been reported in a number of pathophysiological conditions. DLIS which cross-react with anti-digoxin(More)
