Pasture management reshaping dairy cows grazing behavior and performance
Pasture‐based animal production has assumed in the last decade an outstanding importance all around the world (Mannetje et al.2007).This fact is mostly related to economic advantages,animal welfare,and ecological issues ( Murphy et al.1996).The viability of small family farms,through pasture‐based ecological dairying,has been highlighted as a way to revitalize rural communities and avoid urban social problems in South America ( Rizzoli et al.2007).Management methods determine synchronized grazing behavior responses ( Taweel et al.2006).Dairy cows can be expected to anticipate being moved to a fresh paddock after milking and synchronize their behavior to this prediction.This results in reduction of grazing time and intake,especially around reward time ( Arriaga‐Jordan and Holmes 1986).This experiment tested the effect of paddock management in reshaping behavioral patterns of cows to improve use of the pasture resource.
