We studied the kinetics of lysine, methionine, and threonine in six high-yielding dairy cows at peak lactation (stage 1) and 6 mo later (stage 2). The cows were fitted with cannulas in the rumen and… Expand
Oxygen uptake in fowl eggs incubated in air and pure oxygen.
1. The oxygen uptake of small (bantam hen) and large (white leghorn) domestic fowl eggs was measured during incubation in air and pure O2. 2. A 2 hr exposure to pure O2 increased the O2-uptake from… Expand
Body temperatures in pigeons and budgerigars during sustained flight
- A. Aulie
- 1 June 1971
Abstract 1. 1. During flight birds have more than eight times higher heat production than during rest. 2. 2. This resulted in hyperthermy in pigeons during all flights at ambient temperatures between… Expand
Effect of cold acclimation on the oxidative capacity of skeletal muscles and liver in young bantam chicks
1. 1. The effect of intermittently cold exposing newly hatched bantam chicks on the activities of cytochrome c oxidase of skeletal muscles and liver, have been investigated. 2. 2. The cytochrome… Expand

Considerable heterogeneity unrelated to the effect of gravity has been demonstrated for both local ventilation (V) and perfusion (Q) in the lung. Local ventilation and perfusion are well matched, so… Expand

Abstract o 1. The O2 consumption, EMG from m.pectoralis major and body temperatures during cold exposure were measured and the weights of pectoral muscles, leg muscles and liver recorded in ptarmigan… Expand
Concentrations and Flow of Free Amino Acids in Ruminal and Duodenal Liquid of Dairy Cows in Relation to Feed Composition, Time of Feeding and Level of Feed Intake
The main purpose of this study was to examine sources of variation in free amino acids (FAA) in the rumen and their relative contribution to the total duodenal amino acid supply. Six cannulated… Expand
Metabolic thermoregulatory responses in eggs and chicks of willow ptarmigan (Lagopus lagopus).
Abstract 1. 1. The CO2 production in eggs and chicks of willow ptarmigan has been measured during cold exposure. 2. 2. Fourteen-day-old embryos showed no sign of thermoregulation. In the fully… Expand
Effects of hypoxia on the metabolism of embryos and chicks of domestic fowl.

Oxygen consumption and blood lactate concentration were measured in embryos (days 17-20) and chicks (days 0-7) in air and in 7-8% O2. The specific oxygen consumption in air increased up to day 4… Expand
Human pharmacokinetics of iohexol. A new nonionic contrast medium.
The pharmacokinetics of iohexol, a new nonionic, water-soluble contrast medium, have been determined after intravenous injection in 20 healthy volunteers, at four different dose levels (125-500 mg… Expand
