Immediately after the milk or cream has been measured a record shall be made showing the date, the producer's name or number, and the weight or volume of milk or cream received, and such record shall be available to the director at all reasonable times and each producer of said milk or cream shall upon request within twenty-four hours following each daily delivery be furnished a duplicate statement giving the date and the weight or volume of milk or cream delivered, and in addition the person receiving the milk shall furnish to each producer a record of the daily weight or volume of milk or cream received and the test thereof for each period of delivery. Such period of delivery shall not exceed sixteen days and the statement required to be furnished to producers shall be furnished within six days after the end of such period of delivery. If in the opinion of the director it will effectuate the purpose of this act he may require an individual licensee to furnish each producer with a duplicate record of the weight or volume of milk or cream received immediately following each delivery of such milk or cream.
