A comparison of methods of recovering oesophageal extrusa from grazing sheep

Grass and Forage Science, 1978
AbstractExtrusa samples were collected from two groups of oesophageally fistulated sheep grazing together. One group had foam plastic oesophageal plugs fitted below the fistula to assist in the complete collection of extrusa; the second group grazed without plugs.

ESTIMATION OF THE BOTANICAL COMPOSITION OF OESOPHAGEAL EXTRUSA SAMPLES. 1. A MODIFIED MICROSCOPE POINT TECHNIQUE

Grass and Forage Science, 1975
ABSTRACTExtras samples were collected from ocsophageally fistulated sheep that had been fed mixtures of known proportions of a legume and a grass. The botanical composition of these samples was estimated by two microscope point techniques. When estimates were made by recording hits on each species the legume content of the ingesta was consistently ...

Esophageal Plug and Fasting Effects on Particle Size Distribution and Quality of Extrusa from Grass Pastures

Agronomy Journal, 1989
AbstractDiet selection and mastication by cattle (Bos taurus L.) can be examined using extrusa from esophageal fistulas. Experiments were conducted to investigate the use of an esophageal plug and the influence of a 16‐h fast, prior to collection, on the particle size distribution and quality of masticated forage.

Differences between the in vitro digestibility of extrusa collected from oesophageal fistulated steers and the forage consumed

Animal Production Science, 2009
In a study that included C4 tropical grasses, C3 temperate grasses and C3 pasture legumes, in vitro dry matter digestibility of extrusa, measured as in vitro dry matter loss (IVDML) during incubation, compared with that of the forage consumed, was greater for grass extrusa but not for legume extrusa.

ESTIMATION OF THE BOTANICAL COMPOSITION OF OESOPHAGEAL EXTRUSA SAMPLES. 2. A COMPARISON OF MANUAL SEPARATION AND A MICROSCOPE POINT TECHNIQUE

Grass and Forage Science, 1975
ABSTRACTThe botanical composition of extrusa collected from oesophageally fistulated sheep fed diets of known proportions of a legume and a grass was estimated by manual separation and a microscope point technique. The microscope hits were adjusted for the weight per unit area of each plant component in order to estimate composition by weight.

Reliability of extrusa samples collected from steers fistulated at the oesophagus to estimate the diet of resident animals in grazing experiments

Australian Journal of Experimental Agriculture, 1987
The legume content of the diet of groups of resident cattle (LDR) continuously grazing a number of grass-stylo pastures was determined by the faecal carbon isotope ratio ( 13C) technique on various occasions. At the same time the pastures were sampled by non-resident steers fistulated at the oesophagus (OF steers) and the legume content of their ...
