The Effects of a Dietary Immunomodulatory Supplement on the Immune-Metabolic Axis in Growing Beef Cattle

Creator:: Armstrong, Shelby A.
Abstract:: To evaluate the immunologic and metabolic effects of OmniGen-AF® (Phibro Animal Health corporation, Quincy, IL; OG) supplementation in growing beef cattle, we designed three studies using replacement beef heifers (8.5 and 10.5 months of age) and steers supplemented across backgrounding, transition, and finishing periods. In Study 1, the effect of...

Effects of two forms of intrareticular selenium supplements on beef cow selenium status and on the transfer of selenium from dam to offspring

Creator:: Campbell, Donald T.
Abstract:: Two concurrent studies were conducted to evaluate the effect of selenium (Se) supplementation on beef cows. Trial 1 was designed to evaluate the safety and efficacy of two intrareticular Se supplementation delivery systems. Trial 2 was designed to evaluate the transfer of Se across the placenta and through the colostrum...

Canola meal as a protein supplement in dairy rations

Creator:: Sanchez, Jorge Ml.
Abstract:: A four months continuous feeding trial was conducted to evaluate Canola meal as a single protein supplement in complete dairy rations. Thirty high producing Holstein cows in the second week of lactation were randomly alloted in groups of ten to one of three isonitrogenous (15% CP) and isocaloric (1.6 Mcal/kg...

Urinary estrogens and progestins in pregnant pony mares

Creator:: Riad, Mohamed Tarek
Abstract:: Urinary steroids have been studied during early and late pregnancy in domestic horses or sporadic samples at various stages of pregnancy in wild equidae. In our studies, urinary estrone sulfate (E1S) and pregnanediol glucuronide (PdG) were monitored throughout pregnancy in six pony mares by enzyme immunoassay (EIA). Both hormones were...
