Reasons for culling of Holstein dairy cows in Neishaboor area in northeastern Iran %K Culling %K Holstein %K Dairy cow %K Iran %R 10.22099/ijvr.2009.1709 %X This study was designed to determine the culling rates of 23 Holstein dairy herds (with an average size of180 cows per herd) in Neyshabur area in northeastern Iran over a period of three years from 2001 to 2003.The average annual culling rate was 13.1%, (98.5% involuntary and 1.5% voluntary). Of the total disposals(1612 cows), 53.48% were culled by the end of five years of age. Poor fertility was the most important reason for culling (34.9% of disposals), followed by digestive disorders (12.6%), alimentary problems (10.85%),mastitis (9.6%) and lameness (8.3%). More detailed epidemiological studies are needed to plan and implement healthcare programs. These programs targeted toward diseases that lead to culling would be prerequisite for a profitable farming. %U https://ijvr.shirazu.ac.ir/article_1709_b984f2524572793873b0043bd78e32fc.pdf
