Vitamin E was first described in 1922 as an unknown factor required for impregnated rats to carry their offspring to term. In fact, when vitamin E was chemically characterized it was given the name "tocopherol" derived from the Greek: tokos = childbirth; phero = to bear; and –ol, indicating an...
An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes. A vitamin E-deficient diet of low rancidity produced a severe microcytic anemia with strong immature red cell response and granulocytosis occurring 2 to 4 weeks before a drop in hemoglobin and hematocrit...
We have previously shown that diets enriched with (n-3) fatty acids reduced the delayed-type hypersensitivity (DTH) skin reaction to keyhole limpet haemocyanin (KLH) in geriatric-Beagles. Although the amount of α-tocopheryl acetate in diets of the previous study exceeded requirements, plasma α-tocopherol concentration was significantly lower in dogs fed the high...
Milk fever (MF), retained placenta (RP), and left displaced abomasum (LDA) are three common and costly metabolic diseases in cows during the first days of lactation. Some studies suggest that circulating concentrations of α-tocopherol (ATOC) are decreased by these three diseases. It is, however, unknown if and how long lower...

Cystic ovarian disease (COD) is an anovulatory condition in cattle
that afflicts between 6-18% of all dairy cows in the US. Ovulation is
dependent on the plasminogen activator (PA) family of proteases
and protease inhibitor for proteolysis, culminating in follicular rupture.
Failure of the follicle to ovulate suggests an aberration...
Commercial hog diets in the United States commonly contain lipid sources high in polyunsaturated fatty acids, most notably linoleic acid (18:2). This may result in greater deposits of linoleic acid in pork adipose tissue, contributing to an increased potential for lipid oxidation, high n-6/n-3 fatty acid ratio and increased fat...
