在维多利亚的Goulburn Valley地区,大约90,000公顷灌溉的多年生牧草用于放牧奶牛。从该地牧场所获得的平均乳产量低,如乳脂产量仅为333公斤/公顷。响影牧场单位面积产量的一个重要因素是奶牛采食的牧草比例不当,这可以通过增加放牧强度来解决。增加放牧强度通常可以提高从每公顷牧场所获得的乳产量,同时也能改变牧草的数量、成分和质量。影 About 90,000 hectares of irrigated perennial grasses are used to graze dairy cows in the Goulburn Valley area of ​​Victoria. The average milk yield obtained from this pasture is low, for example, the fat production is only 333 kg / ha. An important factor in the production of a shadow pasture per unit area is the inappropriate proportion of pasture grazed by the cow, which can be overcome by increasing the intensity of grazing. Increasing the intensity of grazing usually increases the amount of milk produced per hectare of pasture, while also changing the quantity, composition and quality of forage. shadow
