Observation

This question was well attempted by the candidates. Though most of the candidates were unable to give the correct names of the parts labeled in the diagram, they could state the management practice that had been carried out on the part labelled II. They could also give reasons for carrying out debeaking and mention the devices that could be used to carry out debeaking as required in 3(a, bi-iii). However, most of the candidates could neither state the precautions that should be taken when carrying out debeaking nor name bacterial diseases of chicken as required in 3(b)(iv) and 3(c) respectively.

The expected answers include:

3. (a) Name of the parts labelled II and III
