1. AVALIAÇÃO DE COMPONENTES DA FIBRA COMO MARCADORES INTERNOS E DE ALCANOS PARA ESTIMAR O FLUXO DE DIGESTA NO DUODENO DE BOVINOS / EVALUATION OF FIBER COMPONENTS AS INTERNAL MARKERS AND ALKANES FOR DUODENAL DIGESTA FLOW ESTIMATION IN CATTLE
The use of ADF as internal Marker of duodenal digesta flow was evaluated, for this the intestinal degradability of fiber was studied. Four Holstein calves (156 33 kg), fitted with duodenal cannula T simple, and one calve fitted on the rumen, fed diet base with black oat and supplement, was used. Seven feeds were weighted on the polyester bags (7x5,5cm; 25

2. Duodenal bulb control of the flow rate of digesta in the fasted and fed dog.
1. Continuous measurement of the flow of digesta near the pylorus, and 5 cm aborally, was assessed in the conscious dog using a chronically implanted flowmeter. The patterns of flow were related to motor activity of the gastroduodenal junction. 2. Electromagnetic measurement of the flow was calibrated in vitro by means of a pulsatile pump. Validation was obt

3. Effect of duodenal cannulation on abomasal emptying and secretion in the preruminant calf.
1. The effect of re-entrant cannulation of the duodenum on digesta flow from, and secretion into, the abomasum of the preruminant calf was studied. 2. Calves fitted with abomasal cannulas and, at the same time or later, with re-entrant duodenal cannulas were given, by abomasal infusion, test feeds containing glucose and minerals. Net volumes of secretory flu

4. Initiation of the migrating myoelectric complex in dogs.
1. Contractile and spike activity in the conscious dog were recorded from strain gauge force transducers and electrodes chronically implanted on the antrum, duodenum and jejunum. The pattern of activity was related to the time elapsed after feeding a daily meal, both in intact dogs and in dogs with antro-jejunal or oesophago-duodenal anastomoses. 2. From 8 t
