Our objective was to determine the influence of CP supplementation frequency
(SF) on cow performance, grazing time, distance traveled, maximum distance from
water, cow distribution, DMI, DM digestibility, harvest efficiency (HE), percentage of
supplementation events frequented, and CV for supplement intake for cows grazing
low-quality forage. One hundred-twenty pregnant (approx....
This study was designed to confirm or refute the tenderizing
effect of ultra-hydrostatic pressure on warm excised pre-rigor
muscle, plus to take a thorough look at its effect on some meat
characteristics of economic importance.
Samples for the experiment were obtained from animals (cattle
and sheep) slaughtered at Oregon State...
Bone is much more than a simple, static organ. While its classical functions of mineral storage, organ protection, and locomotion still hold true, further studies into the skeleton have revealed a dynamic system capable of signaling, communication, remodeling, and responding to various stimuli. Overall skeletal health is critically important to...
Several experiments were conducted to examine the toxicity of Senecio jacobaea (SJ) in animals resistant to pyrrolizidine alkaloid (PA) intoxication and to determine the extent of alterations in mineral metabolism as a result of SJ intoxication. Inclusion of SJ into diets containing added copper (Cu) resulted in increased (P<.01) liver...
Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...
The first goal of this study was to evaluate the roles of different intracellular
proteolytic systems in accelerated skeletal muscle protein degradation. Total,
myofibrillar and non-myofibrillar proteolysis were determined in cultured L8/CID
muscle cells. Calpain proteolysis was assessed by over-expressed calpastatin inhibitory
domain (CD). Lysosomal proteolysis was determined in the...
This study was conducted to determine the relationships among the
linear type traits of rump angle, rump width, rump length, rear legs
side view, rear legs position, rear legs rear view, tailhead, vulva
angle, mobility, pasterns, foot angle, and toes with reproductive
performance (days open and times bred) in Holstein...
