This question was popular among the candidates. In 2(a-b), most of the candidates could state the ways of improving pasture and name the organs of the digestive system of a rabbit. However, majority of them could not state the precautions that should be taken in dipping of sheep as required in 2(c).
The expected answers include:
2 (c) Precautions that should be taken in dipping of sheep
- Adhere strictly to manufacturer’s instruction on the use of the
chemical
- Offer water to the sheep before dipping so that sheep may not drink the dipping solution
- The quantity of dipping material in the dipping tank should be sufficient enough to submerge the sheep
- The bath should be stirred from top to bottom occasionally so that the chemical does not settle
- Avoid prolonged submersion in the dip
- Choose a cool, dry weather to ensure quick drying of water on the body of sheep to avoid licking of the solution
- In case of a dipping pool method, ensure that the sheep swims through the dip in one direction
- On completion, the dipping material should be disposed off properly so as not to pollute the environment
- Do not dip sick sheep or sheep with open wounds/injury
- Rams should not be dipped during tupping periods nor ewes during
lambing
- Ensure the potency of the chemical solution
- Lambs before weaning should not be dipped
