A study of feeding value and potential toxicity of pulp mill single cell protein in ruminants

Creator:: Atil, Osman Bin
Abstract:: The objectives of this study were to evaluate the feeding value and potential toxicity of single cell protein (SCP) when fed to ruminants. Three in vivo digestibility trials with lambs, one feedlot trial with steers and one long term feeding trial of high levels of SCP with sheep were conducted...

Genotype x environment interactions in sheep

Creator:: Corum, Kathleen Steele
Abstract:: The 865 ewe production records taken from three lamb crops, were analyzed to study breed effects, heterosis, environmental effects and interactions between them, and breed and heterosis x environment interaction effects on ewe production traits. In each of two environments, approximately 144 ewes were mated in a three breed reciprocal...

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...

Biological and economic effects of flushing and creep feeding in sheep

Creator:: Taiwo, Bolaji
Abstract:: One hundred two mature blackface crossbred ewes were randomly divided into three equal groups to examine the effects of feeding management during mating on blood chemistry, weight change and subsequent reproductive performance. Group I was kept in drylot from 17 days before through 17 days after the start of mating....

Implications of selenium status for various metabolic and performance parameters in beef cattle

Creator:: Drake, Daniel J.
Abstract:: Metabolic and performance parameters of beef calves were compared between Se supplemented (Se) and control (C) dam treatment groups from known Se deficient cattle. Four trials were conducted at three locations involving 50, 36, 25 and 39 experimental dam/calf pairs. Se supplementation was either two 30 gram oral boluses (90%...

Oxytocin synthesis and release by the bovine corpus luteum

Creator:: Abdelgadir, Salaheldin Eltigani
Abstract:: Four experiments were conducted to determine oxytocin concen tration of bovine luteal tissue at different stages of the estrous cycle and to study the effects of prostaglandins F₂α (PGF₂α), E₂ (PGE₂), luteinizing hormone (LH), cycloheximide, colchicine and cytochalasin B on oxytocin synthesis and release in vitro. In experiment 1, luteal...

Effects of sheep grazing to control weeds in a pine plantation on weed reproductive success, trees and sheep performance

Creator:: Milliman, Lisa J.
Abstract:: Use of sheep to control weeds in a ryegrass-white clover pasture in which Knob Cone-Monterrey hybrid pine trees had been planted was investigated in Corvallis, Oregon during 1997-1998. Treatments consisted of an ungrazed control (C) and grazing applications to achieve 25 (L), 50 (M) or 75 (H) percent utilization of...

The NRF2-controlled Antioxidant Response, Alternative Forages, and Selenium supplementation for Improving Ruminant Productivity and Health

Creator:: Ford, Hunter
Abstract:: Oxidative dysfunction can affect dairy animals during periods of heightened stress, particularly during the transition from pregnancy to lactation and during diseases, such as intramammary infection (IMI), and can contribute to increased inflammation, immune dysfunction, and cell death. As such, methods for ameliorating oxidative stress and restoring redox regulation may...
