  • Strategies to consider for getting through current hot dry conditions with reducing pasture cover.

    Pregnancy scan and remove culls to reduce feed demand.

    Avoid condition loss through reducing milking interval, either OAD or 3 in 2.

    Cows feel hot sooner than humans do, once over 21o C Friesians and Crossbreds will start to feel heat stress which will impact production and feed intake (Jersey’s 25o). During hot weather maximise cow intakes by offering cows feed in the coolest part of the day, early in the morning and in the evening. Consider using a sacrifice area with shade for the hottest time of the day. Milking OAD or 3 in 2 can avoid milking in the afternoon heat.

    As pasture covers drop and growth slows consideration can be given to avoiding overgrazing by lengthening the rotation to help with pasture persistence. Some farmers are trying to match rye grass leaf stage development to rotation length by feeding crop and supplement in the morning, using a sacrifice area with shade available during the day and only feeding pasture at night.
