Somatotropin-induced protein anabolism in hindquarters and portal-drained viscera of growing pigs
American Journal of Physiology-Endocrinology and Metabolism, 2003To differentiate the effect of somatotropin (ST) treatment on protein metabolism in the hindquarter (HQ) and portal-drained viscera (PDV), growing swine ( n = 20) treated with ST (0 or 150 μg · kg−1 · day−1) for 7 days were infused intravenously with NaH13CO3 and [2H5]phenylalanine and enterally with [1-13C]phenylalanine while in the fed state ...

Influences of nifedipine on vascular conductance of portally drained viscera, liver and kidney
European Journal of Pharmacology, 1989Nifedipine is a potent vasodilator, which induces various dose-related hemodynamic responses in the gastrointestinal tract, liver and kidney. Blood flow was assessed in anesthetized dogs with non-cannulating electromagnetic flow sensors. Nifedipine was injected into a brachial vein at intervals of 2 min in graded doses from 1-16 micrograms.kg-1.

AbstractBACKGROUNDBetaine and conjugated linoleic acid (CLA) may alter growth and body composition in pigs, although their mode of action is not well understood. Portal‐drained viscera (PDV) have a disproportionate influence with respect to their masses, and this may affect the productivity of more profitable tissues. The objective of this study was to

Abstract The objective of this study was to determine whether circulating concentrations or prior exposure to oestradiol-17β (OE2) and progesterone affected their uptake by splanchnic tissues. Catheters were surgically placed in the portal vein, a branch of the hepatic vein, a mesenteric vein and the abdominal aorta of three multiparous ...

Oxygen consumption by and blood flow across the portal-drained viscera and liver of pregnant ewes.
Journal of Animal Science, 1997The energy requirement of ewes increases during pregnancy. In late pregnancy, approximately 40% of the increase in heat production can be attributed to increases in heat production by nonreproductive tissues. The objective of this study was to determine the pattern of oxygen consumption by the portal-drained viscera (PDV) and liver during pregnancy to ...

SUMMARYThe objectives of this study were (i) to evaluate a new surgical procedure to catheterize hepatic vessels as well as the posterior aorta and vena cava, (ii) to test a modification of a downstream dilution technique in order to measure blood flows through splanchnic tissues and hindquarters in rapid succession, and (iii) to improve the ...

A method was developed to measure metabolic fluxes simultaneously across the portally-drained viscera (PDV), liver, spleen, kidney and hindquarter (HQ) in the conscious pig (20-25 kg). For this purpose, sampling catheters were implanted in the abdominal artery, portal vein, hepatic vein, splenic vein, renal vein and caval vein.

1. Addition of the beta-adrenergic agonist clenbuterol to the diet of steers increased blood flow in portal-drained viscera, liver and tissues of the hindquarters. 2. Uptake of oxygen increased with clenbuterol feeding in hindquarters but not portal-drained viscera or liver. 3.

AbstractBACKGROUNDIn terms of whole‐body metabolism, visceral tissues have a disproportionate influence with respect to their masses, and under certain circumstances their high metabolic rate may compromise nutrient availability to the tissues of productive/economic interest.

Metabolic response to i.v., exogenous insulin was characterized in three younger (355 d old, 340 kg BW) and four older (480 d old, 456 kg BW) beef steers. The steers had chronic indwelling catheters to allow measurement of blood flow and net flux of metabolites across portal-drained viscera (PDV), liver, and hindquarters (HQ).
