Answer:
Option A, C, and D are correct
A. Horses will chew 1 kg of hay longer than 1 kg of grain
C. Saliva is an important buffer of acid in the stomach
D. Teeth wear more rapidly in grazing than browsing animals
Explanation:
•Horses chewing patterns vary, they chew their feeds in different ways. The mouth of a horse makes larger movements and slower movements when chewing hay, compared to when chewing grains. When a horse is chewing hay, it takes more time than when chewing grains, considering both the hay and grain are of the same quantity.
•Saliva tends to help neutralize acid in the stomach, it also helps heal gastroesophageal ulcers. Saliva has a very strong buffering ability against acid in the stomach. So, we can say saliva is an important buffer of acid in the stomach.
•Grazing animals are animals that feed on low grass, while browsing animals are animals that eat high growing leaves. The teeth of grazing animals such as horse, have crowns that grow to help the constant grazing which makes it wear more rapidly than the teeth of browsing animals such to as dogs and cats. To care for the teeth of grazing animals, filing is done instead of cleaning.
•Horses do not salivate in anticipation of a meal, instead, horses produce saliva when there is food in their mouth.
