For the purpose of identification of a bull castrated under sub-section (2) of Section 9 or sub-section (2) of Section 13 shall be branded on the left cheek or neck with a letter “R” not smaller than four centimetres by four centimetres in size or tattooed on the inner side of the left ear with a mark not less than
1.25 centimetres by 1.25 centimetres in size. If the castration is done by the Licensing Officer, the Licensing Officer shall himself get the animal branded or tattooed. If the owner or other person keeping a bull makes his own arrangements for castrating the bull under subsection (2) of Section 9, it shall be the duty of such owner or other person to have the bull branded or tattooed in the manner stated above. In a case a bull previously licensed and marked with letter “L” is subsequently considered unsuitable for breeding purposes and castrated, it shall be marked with the letter “R” and when this is done, the mark “L” shall be deemed to have been cancelled.
