Animal Unit Equivalent (AUE) and Daily Forage Need of Baloochi Sheep while Grazing on Lowland Rangelands in Kerman Province

Hosein Arzani; Saeed Barkhori; Javad Moetamedi; Hosein Azarnivand

Volume 41, Issue 4 , March 2011, Pages 351-362

  Information on animal daily forage needs is essential for an estimation of rangeland grazing capacity. Accordingly, weight and Animal Unit Equivalent (AUE) for each individual class of animal should be determined. Live weights of Baloochi sheep as based on average live weights of 3 and 4 year old ewes ...  Read More
