Body condition score, weight variation and reproductive performance of beef cows in rangelands from the Pantanal region [PDF]

, 2009
Objetivou-se avaliar a influência do escore de condição corporal (ECC) sobre a eficiência reprodutiva de vacas de cria nos períodos pré e pós-parto e a probabilidade de parição, usando o escore de condição corporal e a variação ponderal no período ...

A Body Condition Scoring Chart for Holstein Dairy Cows

Journal of Dairy Science, 1989
Abstract A chart for body condition scoring of freely moving Holstein dairy cows was developed using an iterative process consisting of literature review, interviews with experts, field testing, statistical analysis, and comments from chart users. The chart consists of text and diagrams that detail changes in conformation with body condition change ...

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.

Association between body condition score and live weight in pasture-based Holstein-Friesian dairy cows [PDF]

, 2006
peer-reviewedThe objective was to quantify the strength of the relationship between body condition score (BCS) and live weight (LW) in pasture-based Holstein-Friesian dairy cattle, and to determine the kg LW per unit BCS.

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 ...

BEEF COWS BODY CONDITION SCORING AND ITS MEASUREMENTS RELATIONSHIP

Bulletin Samara State Agricultural Academy, 2020
The purpose of the study is improving the efficiency of breeding work in selection of cows by live weight, body measurements with mandatory consideration of animal condition score. The degree and nature of relationship be-tween live weight and body measurements of beef cows with condition score, regression coefficient were calculat-ed. The research was

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
