Thank you for your feedback.
By Manual Milking Parlor what I meant was a Herringbone Milking Parlor without Milk Meters, Automatic Cluster Removal & Software Automation.
For Buffaloes I have been suggested stationary milking machines which is not very convincing for me. I was planning on having 2 seperate Herringbone Manual Milking Parlor for Cows & Buffaloes.
