Answer- (i) In animal farms the poultry bird and farm animals vaccinated because vaccination helps animals to defence against disease and remains healthy.

Vaccination is very necessary for animals as vaccine not only provides immediate relief from the existing microbes but it mimics the antigen and also stimulates the immune cells inside the animal body to produce antibodies and avoid disease. 

(ii) Yes it is absolutely right that it is very to remove parasites from dairy animals because the dairy animals are mostly affected for infected by the parasites. The external parasites for example: ticks, fleas, lice e.t.c. suck animal’s blood and causes anaemia while the internal parasites such as worms and flukes damages or harms the internal organs of cattle. That is why it is very necessary to remove parasites from dairy animals.

(iii) A sick animal can be identified by several symptoms. Some of the symptoms that can help us to identify a sick animal are as follows:

1. A sick animal can be identified by its improper feeding.

If there is proper clean shelter of animals so that the animals will also remains healthy. This will also increase its production.
