Estimation of Body Weight from Body Size Measurements and Body Condition Scores in Dairy Cows
Journal of Dairy Science, 1997 The objective of this study was to evaluate the use of hip height and width, body condition score, and relevant demographic information to predict body weight (BW) of dairy cows. Seven regression models were developed from data from 972 observations of 554 cows.

Embryonic mortality in Holstein cows on one’s farm
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011 The objective of our research was to evaluate the effect of some factors on the embryonic mortality of Holstein-Friesian dairy cows in a herd. Monitoring was conducted in the course of three years (2006–2009) at a level of (9330–8970) kg/dairy cow per ...

An individual reproduction model sensitive to milk yield and body condition in Holstein dairy cows
Animal, 2013 To simulate the consequences of management in dairy herds, the use of individual-based herd models is very useful and has become common. Reproduction is a key driver of milk production and herd dynamics, whose influence has been magnified by the decrease
