An Investigation into the Situations of Lameness Disease in a Scaleful Diary Farm in Helongjiang Provcince
Summary: Lameness is a common disease among milk cows that is caused by external injuries, bacterial or virus infections, or mal-nutrition. Lameness not only affects milk cows with their breeding and management, but also significantly lowers their productivity. If not dealt with propertly, milk cows with lameness may eventually be laid off. However, limping diseases of a milk cow have complicated causes, higher rates of incidence, longer course, and are often hard to cure, which then seriously affects the milk cow's productivity and life. As a result, such disease can cause huge economic loss to diary cattle industry. By using a 5-grade lameness evaluation method, an experiment was carried out at a scaleful diary farm in Heilongjiang Province, in an effor to analyze the impact of ranching environment and management measures towards lameness of cows.
