Swine exposed to cold air have elevated serum values of total triiodothyronine (TT3) and free T3 (FT3). To characterize the mechanism of these increases, we measured in vivo kinetic parameters after a bolus intravenous injection of 125I-labeled T3 by

The effect of corn-canola meal and corn-soybean meal diets on the form and function of the gastrointestinal tract of broiler (meat-type) and White Leghorn (egg-type) cockerels was measured from 14 to 44 and 14 to 86 days of age or 203 to 1,844 and 11

Fission track analysis (FTA) has been used to investigate the biological uptake of uranium. Examination of fission track maps of black spruce twigs (from areas of uranium mineralization and mill tailings) shows uranium to be concentrated in the inner

A technique of gastrointestinal endoscopy for cattle and sheep is described. To allow passing of an endoscope to specific areas of the gastrointestinal tract, cannulae were placed in the descending duodenum of sheep and the rumen and proximal duodenu

A programmable machine, designed to deliver a pelleted diet from a hopper in independent amounts to six sheep, is described. For commercial alfalfa pellets, the machine dispensed 1.57 g per second of operation over a range of 3–70 sec, with an aver

A variety of factors influence the voluntary intake of ruminants including reticulo-rumen fill or distension (Campling & Balch, 1961; Welch, 1967; Grovum, 1979) and rate of passage of digesta through the gastrointestinal tract (Bines & Davey, 1970).

Total plama cholesterol concentration and radioactivity were measured simultaneously using a gas chromatograph equipped with a flame ionization detector and an effluent splitter. More than 99% of the recovered radioactivity was in the cholesterol pea

Rumen contents were incubated in vitro with acetate-1-14C. Significant amounts of 14C were incorporated into rumen microbial proteins, nucleic acids, and lipids. Serine, glutamic acid, methionine, and cystine were highly labeled, whereas less, or ins

Digesta transfer from the reticulo-rumen to the omasum of a fed steer was filmed in situ using fiberoptic techniques. The reticulo-omasal orifice was not a site of discrimination of the size of digesta particles that leave the rumen. Large particles
