The Digital-Dairy™ line of refractometers is specifically designed to help dairy farmers and calf ranchers to rear healthy calves. Among the many problems plaguing dairy farmers and calf ranchers are the management of waste milk and calf milk replacer, calf dehydration, and the measurement of colostrum quality to prevent failure of passive transfer. MISCO Digital-Dairy refractometers are designed for use on professional dairy farms and calf ranches. Rugged enough to withstand the demands of farm use, yet precise enough to give laboratory-quality readings, the new Digital-Dairy Refractometers provide reliable estimates of the percent solids in waste milk, IgG blood levels, blood plasma protein concentration, colostrum quality, and calf hydration. The instruments are easy to use and require little or no training.
