Policies Regarding Undesirable Genetic Factors in Dairy Goats

Adopted: October 27, 2016

Reason for Policy

Genetic defects resulting in disease have been identified in numerous animal species. These defects and diseases have wide-ranging effects, from mild and manageable to severe and terminal. Passing these genetic defects on to successive generations may cause unnecessary suffering and losses in productivity.

ADGA feels that it is important to proactively develop procedures and programs to aid in the identification and control of genetically related defects and diseases, and provide guidance in helping to identify and manage specific genetic defects in dairy goats.

Process for Identifying Undesirable Genetic Factors

In determining genetic factors that are undesirable, ADGA will consider all relevant data. In order to make such a determination, experts in the field shall be consulted, and their recommendations will be submitted to ADGA along with trait specific data. Upon consideration of this information, the Board of Directors may approve a policy designating procedures for the identification, recording and reporting of carriers of a genetic defect.

ADGA shall maintain a list of undesirable genetic factors that have been identified through genetic testing and for which a policy has been designated by the ADGA Board of Directors.

Process for Identification of Animals With a Genetic Defect

In addition to maintaining a list of undesirable genetic factors, ADGA will provide and update information that includes description of the condition resulting from the defect, inheritance patterns, and the genetic tests available to determine animal status. Information regarding testing resources will be made available through ADGA to its membership and the public. The testing process will incorporate requirements for approved tests, designated laboratories, test forms, and data release forms. Testing, using the approved test(s,) may be conducted by an alternative, approved laboratory.

To be accepted by ADGA, results must be reported from an approved laboratory directly to ADGA and samples must be identified with either the animal’s registration number, or if unregistered, the animal’s tattoo, DOB, breed, and gender.

ADGA shall maintain a database of accepted test results.

Process for Notification, Publication and Release of Information

Following recognition of a specific genetic defect by the ADGA Board of Directors and the establishment of policies for recording and reporting of that defect, testing results will be accepted by ADGA only if provided directly to ADGA by an approved laboratory. The date of implementation of these procedures and policies shall be made available to ADGA members and the public.

Policies regarding registration/recordation of designated carrier animals and/or their offspring shall be established by ADGA and approved by the Board of Directors for each recognized genetic defect.

Testing results and the identification of carriers prior to formal action by the ADGA Board of Directors may be accepted. Policies and procedures for accepting pre-designation testing will be developed for each specific defect as deemed necessary.
