Observation
This question was well attempted by the candidates. In 4(a-b), most of the candidates were able to define the term animal husbandry as well as state the ways in which farm animals are important to humans.
Also, in 4(c)(i-ii), most of the candidates were able to explain the terms ovulation and oestrus. More so, in 4(d), majority of the candidates were able to list the signs that indicate that a ewe is approaching parturition. However, most of them were unable to determine the expected date of lambing of the ewe as required in 4(e).
The expected answers include:
(4) (e) Determination of expected date of lambing of the ewe

Duration of gestation
May = 31 days
