Invited review: Body condition score and its association with dairy cow productivity, health, and welfare
TL;DR: There is relative consistency in the associations among calving and nadir BCS, and BCS change on milk production, postpartum anestrous, the likelihood of a successful pregnancy and days open, therisk of uterine infection, and the risk of metabolic disorders.

Monitoring Metabolic Health of Dairy Cattle in the Transition Period
TL;DR: Methods, strategies, and interpretation of measurement of peripartum concentrations of non-esterified fatty acids and beta-hydroxybutyrate as indicators of aspects of energy status and disease risk are reviewed.
Journal ArticleDOI
Evaluation of nonesterified fatty acids and β-hydroxybutyrate in transition dairy cattle in the northeastern United States: critical thresholds for prediction of clinical diseases.
TL;DR: Postpartum serum NEFA concentration was most associated with the risk of developing DA, CK, metritis, or retained placenta during the first 30 d in milk, although prepartum NEFA and postpartum BHBA were both significantly associated with development of clinical disease.
Journal ArticleDOI
Metabolic Predictors of Displaced Abomasum in Dairy Cattle
TL;DR: Strategic use of metabolic tests to monitor transition dairy cows should focus on NEFA in the last week prepartum and BHBA in the first week postpartum.
Journal Article
Body condition scoring: a rapid and accurate method for assessing health status in mice.
TL;DR: Evaluated the accuracy of the BC scoring technique in assessing the health of mice that have organ en-largement concurrent with declining health; compare the accu-racy of this method with that of using BW for assessing health status in these animals; and determine the interobserver reli-ability of theBC scoring technique.

Principal components analysis
TL;DR: In this paper, the concept of principal components is introduced and a number of techniques related to principal component analysis are presented, such as using principal components to select a subset of variables for regression analysis, detecting outliers, and detecting influential observations.

A Body Condition Scoring Chart for Holstein Dairy Cows
TL;DR: In this paper, 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.
A dairy cow body condition scoring system and its relationship to selected production characteristics [Milk production]
TL;DR: Dairy cows that increased significantly in body condition during lactation were less efficient producers, had a greater number of days open, and had high body condition scores at the end of lactation.

A Dairy Cow Body Condition Scoring System and Its Relationship to Selected Production Characteristics
TL;DR: In this article, a scoring system with 1 to 5 scale was devised to measure body condition of dairy cows at any point during the lactation cycle, based on appearance and palpation of back and hind quarters only.
