Validation of mid-infrared spectrometry in milk for predicting body energy status in Holstein-Friesian cows [PDF]

open access: yes, 2012
Cow energy balance is known to be associated with cow health and fertility; therefore, routine access to data on energy balance can be useful in both management and breeding decisions to improve cow performance.

Body condition score prior to parturition is associated with plasma and adipose tissue biomarkers of lipid metabolism and inflammation in Holstein cows

open access: yesJournal of Animal Science and Biotechnology, 2018
Background Previous research has revealed a strong inflammatory response within adipose (AT) tissue during the transition into lactation. Whether this effect is a result of oxidative stress induced by lipolysis and fatty acid oxidation associated with ...

Impact of prepartum body condition score loss on metabolic status during the transition period and subsequent fertility in Brown Swiss dairy cows

open access: yesJournal of Veterinary Research, 2019
The objectives of this study were to determine the role of a fall in pre-calving body condition score (BCS) in postpartum metabolic status and reproductive outcomes, and gauge the indicativeness of blood metabolites during the transition period.

The evaluation of body condition scoring of Holstein-Friesian cows

open access: yesActa Agraria Debreceniensis, 2008
We carried out the examinations on a farm of 500 cows where We examined the body condition of the stock every month. We recorded the body condition data together with the milk production and calving data. We analysed the daily milk production as well as the body condition.

Metabolic attributes, yield and stability of milk in Jersey cows fed diets containing sodium citrate and sodium bicarbonate

open access: yesPesquisa Agropecuária Brasileira, 2013
The objective of this work was to evaluate the inclusion of sodium citrate and sodium bicarbonate in the diet of lactating Jersey cows, and its effects on the metabolic attributes, productivity and stability of milk.

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

open access: yes, 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.

Impact Evaluation of Score Classes and Annotation Regions in Deep Learning-Based Dairy Cow Body Condition Prediction

open access: yesAnimals, 2023
Body condition scoring is a simple method to estimate the energy supply of dairy cattle. Our study aims to investigate the accuracy with which supervised machine learning, specifically a deep convolutional neural network (CNN), can be used to retrieve ...

Genetic profile of total body energy content of Holstein cows in the first three lactations [PDF]

open access: yes, 2005
Weekly total body energy content (TBEC) was calculated for 444 Holstein cows in their first 3 lactations. These calculations were based on body lipid and protein changes predicted from weekly changes in body condition score and live weight of each cow ...

A Body Condition Scoring Chart for Holstein Dairy Cows

open access: yesJournal 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

open access: yesJournal 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.
