Brief communication: Ewe ultra-sound pregnancy diagnosis and its use by New Zealand farmers. Paper presented at the Proceedings of the New Zealand Society of Animal Production, Napier.0370-2731https://hdl.handle.net/10182/9972Ultra-sound pregnancy diagnosis can be a valuable management tool for sheep farmers. The benefits include early identification of non-pregnant (dry) ewes which can be culled, freeing up valuable feed for pregnant ewes (Blair 1986) and the identification of single, twin and triplet fetuses, allowing ewes to be fed based on their specific nutritional requirements during pregnancy (Garrick 1998). In addition, selection of lambing paddocks can be made based on the number of fetuses identified (Garrick 1998).65-67en© NZSAP.
