- What is artificial insemination? [2 marks]
- State four advantages of artificial insemination. [4 marks]

Observation
This question was well attempted by the candidates. In 4(a-b), most of the candidates were able to state the reasons why livestock distribution is concentrated in the savannah region of West Africa but they could not calculate the number of White leghorn fowls that could be kept in a deep litter house. Further to this, most of the candidates were able to define artificial insemination, state the advantages of artificial insemination and define floriculture as required in 4(c-e) but they could not list examples of ornamental plants used as hedges in West Africa as required in 4(f).
The expected answers include:
4(b) Calculation of the number of fowls to be kept in the deep litter house
Recommended space for white leghorn = 3 fowls/m2
Area of deep litter house = 20m x 100m = 2000m2
No of white leghorn fowls to be kept in the deep litter house
= 2000 x 3
= 6000 white leghorn fowls
