Comparisons of diets of sheep and cattle grazing together on sown pastures on the Southern Tablelands of New South Wales by principal components analysis

摘要: The botanical and chemical composition of the diets oesophageal fistulated wether Merino sheep cattle (mainly yearlings dry cows) were compared when they grazed together on sown pastures varying widely in yield composition. Sheep consistently different from diets, independent pasture conditions, having lower normal-acid fibre contents (3.8 units lower), higher water-soluble carbohydrates (1 unit) vitro digestibility (4.4 units). Differences nitrogen content diet related, part, to being grazed. It is suggested that differences arise between their mechanical ability be selective. Use principal components technique allowed reasonable biological conclusions drawn multivariate intercorrelated data.
