If  a  horse   is  found  with the bone, tissues, muscles or tendons of its tail cut as   aforesaid and with the wound  resulting  therefrom  unhealed,  upon  the   premises  or in the charge and custody of any person, such fact shall be   prima facie evidence of a violation of this section by the owner or user   of  such  premises  or  the  person  having  such  charge  or   custody,   respectively.2.  Any  person  who shows or exhibits at any horse show or other like   exhibition in this state a horse, mare or gelding, the tail of which has   been cut or operated upon in the  manner  referred  to  in  section  one   hereof,  is  guilty of a misdemeanor, punishable by imprisonment for not   more than one year, or by a fine of not more than five hundred  dollars,   or by both; provided that the provisions of this section shall not apply   with  respect to an animal the tail of which has been so cut or operated   upon, if the owner thereof furnishes to the manager  or  other  official   having  charge  of  the horse show or exhibition at which such animal is   shown  or  exhibited  an  affidavit  by  the  owner,   or   a   licensed   veterinarian,  in a form approved by the state department of agriculture   and markets, stating either that the tail of such horse was so cut prior   to June first, nineteen hundred sixty-four, or that it was so cut  in  a   state  wherein  such cutting was not then specifically prohibited by the   laws thereof. Said affidavit shall, to the best of affiant's  knowledge,   information  and  belief,  identify the animal with respect to sex, age,   markings, sire and dam, and state either that the cutting was done prior   to June first, nineteen hundred sixty-four, or the  time  and  place  of   such  cutting  and the name and address of the person by whom performed.   The affidavit shall be subject to inspection at all reasonable times  by   any  peace  officer,  acting  pursuant  to his special duties, or police   officer of  this  state,  or  by  a  designated  representative  of  the   commissioner.  In  lieu  of  furnishing such affidavit to the manager or   other official having charge of such horse show or exhibition, the owner   of such horse may specify on the entry  blank  for  the  horse  show  or   exhibition  the name and address of a central registry office designated   by the state  department  of  agriculture  and  markets  where  such  an   affidavit has already been filed and is available for inspection.
