Observation

    This question was poorly attempted by the candidates. Most of them could neither explain the mating systems in livestock management nor draw and label the digestive tract of a hen
correctly as required in 4(a-b). However, majority of them were able to give the reasons why ornamental plants are important as required in 4(c).
The expected answers include:

4(a)      Explanation of systems of mating in livestock management
Stud/ hand mating                                                                                               
This involves keeping a proven sire in a stud where any dam on heat is brought for mating and there after the dam is taken away

Pen mating                                                                                                            
A group of female animals on heat are brought into the male’s pen for mating
OR
Pen mating involves one male and several female farm animals                              

Flock/ pasture mating                                                                                          
This is a system in which both the sires and dams are allowed to move together and mate freely                                                                                         

(b)        Drawing and labelling of the digestive tract of a hen
