Experimental reduction of food quality is not compensated with increased food intake in high-arctic muskoxen (Ovibos moschatus)

A total of four barren adult female muskoxen (Ovibos moschatus) were used over a period of 2 years for the purpose of the present study. During the first year, the natural changes in appetite (ad libitum intake of standard pelleted reindeer feed) and body mass were determined in two of the animals....

Description
Summary:A total of four barren adult female muskoxen (Ovibos moschatus) were used over a period of 2 years for the purpose of the present study. During the first year, the natural changes in appetite (ad libitum intake of standard pelleted reindeer feed) and body mass were determined in two of the animals. During the second year, the effect of reduced food quality on ad libitum food intake was tested in all four animals in July when the appetite had been found to be at a high. We found that the experimentally reduced food quality was not compensated with increased food intake in these large high-Arctic herbivores.
