There’s a lot of talk these days about different grazing systems. Mob grazing, management intensive grazing (MIG), ultra-high stock density (UHSD) grazing and tall grass grazing systems. Most concentrate on beef cattle production. But can these systems translate to dairy cows? In a system where dairy profitability and milk production is dependent upon excellent forage quality and dry matter intake, can these type of grazing strategies make sense?
Mena Hautau, field and forage crop educator with Berks County Extension, recently decided to take a look at what type of “mob grazing” was already happening on southeast Pennsylvania grazing dairies. A Northeast Sustainable Agriculture Research and Education grant allowed her to observe grazing systems on four dairies which have already incorporated some type of intensive, managed grazing system, and are grazing tall grass, using frequent rotations, and grazing in higher densities. They were also all certified organic, although this was not intentional, and all were being managed by dairymen with more than two decades of experience. The dairies are grazing-based dairies with little grain or total mixed rations being fed. [Read more…]
