QUESTION 3
  (a)      Define the following terms:

  1. hay                                  
  2. silage.              [4 marks]
  3.   (b)(i)Name two types of pasture.    [2 marks]
                (ii) State four advantages of establishing a grass-legume pasture.          [4 marks]
                (iii)       State three advantages of rotational grazing. [3 marks]
      (c)       Draw and label the digestive tract of a hen. [7 marks]
_____________________________________________________________________________________________________
OBSERVATION

This question was poorly attempted by the candidates.  In 3(a)(i – ii), majority of the candidates could not define the terms hay and silage.  In 3b(i – iii), though, most of the candidates were able to name the types of pasture but majority of them could neither state the advantages of establishing a grass-legume pasture nor state the advantages of rational grazing.

Also, most of the candidates could not draw and label the digestive tract of a hen as required in 3(c).

The expected answers include:
(3) (a)              Definition of the terms hay and silage
            (i)        Hay
This is a cut and dried forage (stored) for feeding farm animals
                                                     
                        Silage             
This is a cut and fermented forage in an anaerobic condition
for feeding farm animals
                             
   (b)   (ii)         Advantages of establishing a grass-legume pasture
              -           It suppresses weed
-           Improves nutritional quality of the forage/balanced diet
              -           Legumes fertilize the soil for grass to grow/nitrogen fixation
              -           Optimal usage of the land
              -           It enhances proliferation of soil fauna and flora leading to
                         improved soil structure, texture and aeration
              -           Reduces evapotranspiration or water loss
              -           It prevents erosion
              -           Legume trails on the grass for more production/High yield/
                          improved income
              -           Legume serves as source of protein for the livestock
              -           It is more acceptable to ruminants
              -          It reduces leaching

 (iii)       Advantages of rotational grazing
-           Prevents overgrazing
              -           Allows for the regeneration of grazed forage
              -           It controls parasites/diseases/pests
              -           Promotes efficient utilisation of pasture
              -           Reduces soil compaction/maintenance of soil structure
