Feeding Dairy Cows for Body Condition Score [PDF]

, 2008
Changes in body weight are not a very good indicator of the nutritional status of dairy cows. For example, while the gut contents of a 1400 lb. dairy cow weigh approximately 200 lbs., the cow has a daily intake of nearly 100 lbs.

Body Condition Scoring of Dairy Cows Based on Feature Point Location

IEEE Access
The use of computer vision to estimate the Body Condition Score for cow has demonstrated to be feasible. However, most research has been limited to fixed camera positions, which restricts the technique’s usefulness. This research acquired cow data at various distances and angles to investigate the impact of distance and different depth images ...

Comparison of a classical with a highly formularized body condition scoring system for dairy cattle

Animal, 2014
Body condition scoring is a common tool to assess the subcutaneous fat reserves of dairy cows. Because of its subjectivity, which causes limits in repeatability, it is often discussed controversially.

Associations among body condition score, body weight, and serum biochemistry in dairy cows

Journal of Dairy Science
Body condition score and BW yield insights into body tissue reserves and diet, and serum biochemical measures reflect the metabolic status of cows. Associations between body composition measures and biochemistry are unclear and investigation may reveal important information on the metabolic and physiological status of cattle with varying levels of ...
