OBSERVATION

 This question was very popular among the candidates.  In 8(a-d), majority of the candidates were able to state what is meant by animal improvement, give the aims of animal improvement, define the terms parturition and gestation period as used in livestock reproduction and name the systems in the body of farm animals. However in 8(e) most of them were unable to mention the advantages of castration in animal production.

The expected answers include:

(e)    Advantages of castration in animal production
-    Castrated animals grow faster
-    Removal of odour from meat
-    Makes animal docile and easier to handle
-    Produces tender meat quality
-    Reduces the incidence of venereal diseases in the flock
-    Animals with undesirable qualities are prevented from mating.
