Effects of high-copper feeding on portal ammonia absorption and on oxygen consumption by portal vein-drained organs and by the whole animal in growing pigs.
Growing gilts that had catheters inserted into the portal vein, ileal vein, and carotid artery and that were trained to consume 1.2 kg of a 16% CP corn-soybean meal basal diet once daily were used. In Trial 1, hourly simultaneous measurements of the O2 consumption by portal vein-drained organs (PVDO) and by the whole animal during the 24- to 30-h postprandial period were conducted in eight pigs...
متن کاملNet absorption and oxygen consumption by Holstein steers fed alfalfa or orchardgrass silage at two equalized intakes.
The objective of this experiment was to compare net nutrient absorption and oxygen consumption by portal-drained viscera (PDV) of catheterized Holstein steers (333 kg) when fed alfalfa or orchardgrass silage at two equalized intakes. The design was a 4 X 4 Latin square with a 2 X 2 factorial arrangement of alfalfa or orchardgrass fed at 65 or 90 g dry matter/kg.75 live weight daily. Blood flow ...

Physiol. 22 l(2) : 427-43 1. 197 l.-Forced treadmill running caused rat muscle and rectal temperatures to increase 8.1 and 5.1 C, respectively. After exercise, muscle temperature fell exponentially but did not reach control values in an hour. ...
متن کاملVariation in the link between oxygen consumption and ATP production, and its relevance for animal performance
It is often assumed that an animal's metabolic rate can be estimated through measuring the whole-organism oxygen consumption rate. However, oxygen consumption alone is unlikely to be a sufficient marker of energy metabolism in many situations. This is due to the inherent variability in the link between oxidation and phosphorylation; that is, the amount of adenosine triphosphate (ATP) generated ...
متن کاملEnergy cost of NaCl transport in isolated gills of cutthroat trout.
Few studies have made direct estimates of the energy required for ion transport in gills of freshwater (FW) and seawater (SW) fish. Oxygen consumption was measured in excised gill tissue of FW-adapted cutthroat trout ( Oncorhynchus clarki clarki) to estimate the energy cost of NaCl transport in that osmoregulatory organ. Ouabain (0.5 mM) and bafilomycin A1 (1 μM) were used to inhibit the Na+-K+...
