Question 2
Study specimens C,D,E and F and answer the questions that follow.
(a) (i) State two harmful effects of each of specimens J, K and L in livestock production.
(ii)State two ways of controlling each of specimens J, K and L on livestock Farms. [12 marks]
(b) Mention three other storage pests in farm animal production. [3 marks]
Observation
This question was fairly attempted by the candidates. The question sought to test candidates’ knowledge and familiarity with field and storage pests in livestock production. Majority of the candidates did not give correct response to the questions because they could not correctly interpret the questions. Most of the candidates’ answers were towards the farm animals rather than how the field and storage pests affected their feed.
(a)(i) Many candidates could not correctly state the harmful effects of specimens J (Soldier Ants), K (Weaver bird) and L (Weevil) in livestock production.(ii) Many candidates could not also correctly state the methods of controlling specimens J, K and L. (b) Many mentioned pests that are not even related to storage pests.
The expected answers include:
