Where do the sheep and the cattle stand? What condition are they in and why
Answers
Answer:
Animals are divided into three groups:
· Carnivores which eat meat,
e.g. dog, lion
· Omnivores which eat meet end plants,
e.g. pig
· Herbivores which eat plants
e.g. cow, horse
The digestive system of omnivores and carnivores is as described in Unit 3. In herbivores the digestive system is very large because they eat large amounts of grass.
· The horse, donkey and mule are herbivores but do not chew the cud. They are non-ruminants.
· Cattle, goats, sheep and buffalo chew the cud. They are ruminants.
The rumen (stomach)
The stomach of a ruminant has four chambers. The first chamber is very large and is called the rumen. The second chamber is the reticulum (honeycomb). The third is the omasum (book) and the fourth is the abomasum (the true stomach). The ruminant chews grass and swallows and it goes into the rumen.
