Interactions of forage quality and physiological state on forage intake of grazing beef cows in autumn

摘要：

Intake by grazing cattle is affected by quality and availability of forage and by physiological demands, such as lactation and gestation.However, limited information is available on how these factors interact.We tested the hypothesis that autumn forage intake is altered by the interaction of cow physiological state and forage quality using cows in different stages of lactation and gestation grazing forages varying in digestibility.
