The importance of the sense of smell to the grazing sheep

Extract

1. A series of experiments was carried out to assess the importance of the sense of smell to the grazing sheep.

2. The results of the first two experiments described indicated that the sense of smell is of importance in the initial stimulation of appetite, but under the experimental conditions the selection of particular herbage species was not affected.

3. Further experimentation showed that, because of its adaptation character, olfaction can only be of supplementary importance in influencing the food selection of the grazing sheep.
