AGENDA 2. REPORT ON GOAT MILK RECORDING – RESULTS FROM THE ON‐LINE DATA BASE

CONCLUSIONS• Increase members’

interest to the yearly

enquiry, – Especially from the countries with large goat

populations

• On‐line database – to be enlarged with data– On milk composition (fat, protein) – On diseases in goat flocks

AGENDA 3. HARMONIZATION OF THE GUIDELINES FOR GOAT MILK RECORDING

• SECTION 2.3 ‐

ICAR RULES, STANDARDS AND GUIDELINES FOR MILK RECORDING IN GOATS

• Need revision and harmonization – Guidelines are contradictory in some parts and

should be clarified– Some parts are repeated

• Material with proposed changes has been prepared and disscused at meeting in Cork


AGENDA 3. HARMONIZATION OF THE GUIDELINES FOR GOAT MILK RECORDING

CONCLUSIONS• In next month we expect final material• Revised

material

will

be

sent
