TLDR
Cows in the highest quartile for PMN% at both D28 and D42 had lower pregnancy rates, took longer to conceive, and had a lower milk yield than those in the lower PMN%.About:

Journal ArticleDOI
A review of the ongoing discussion about definition, diagnosis and pathomechanism of subclinical endometritis in dairy cows.
TL;DR: The impact of subclinical endometritis on reproductive performance is characterized by decreased conception rates, and prolonged days to first service and days open, and it has been demonstrated that subclinicalendometritis has an impact on survival and quality of the embryo.
Journal ArticleDOI
The relationship between endometrial cytology during estrous cycle and cutoff points for the diagnosis of subclinical endometritis in grazing dairy cows
Laura Vanina Madoz,Mauricio Javier Giuliodori,María Jaureguiberry,J. Plöntzke,Marc Drillich,R.L. de la Sota,R.L. de la Sota +6 more
TL;DR: The risk for false positive test results as a consequence of physiological changes in the counts of PMN during estrous cycle is low and subclinical endometritis diagnosed at 21 to 62 DIM decreases the hazard for pregnancy and increases the calving to conception interval by d30 compared with normal cows.
Journal ArticleDOI
Reproductive tract inflammatory disease in postpartum dairy cows.
TL;DR: Factors that may contribute to postpartum reproductive tract inflammatory diseases in dairy cows are reviewed and their inter-relationships, impacts and treatment are reviewed.
Journal ArticleDOI
Assessing and Managing Body Condition Score for the Prevention of Metabolic Disease in Dairy Cows
TL;DR: Body condition score (BCS) is an assessment of a cow's body fat (and muscle) reserves, with low values reflecting emaciation and high values equating to obesity.

Calving body condition score affects indicators of health in grazing dairy cows
John R Roche,Kelli P. A. MacDonald,Karin E. Schütz,L.R. Matthews,G.A. Verkerk,Susanne Meier,Juan J. Loor,A.R. Rogers,J. McGowan,S.R. Morgan,S. Taukiri,James R. Webster +11 more
TL;DR: The results highlight that calving BCS and, therefore, BCS through early lactation are not effective indicators of functional welfare, with the analyses presented indicating that both low and high BCS at calving will increase the risk of disease.

Defining and diagnosing postpartum clinical endometritis and its impact on reproductive performance in dairy cows.
Stephen J. LeBlanc,Todd F. Duffield,Ken E. Leslie,K G Bateman,Greg Keefe,J.S. Walton,Walter H. Johnson +6 more
TL;DR: Testing for diagnostic criteria for clinical endometritis in postpartum dairy cows found no diagnostic criteria based on palpation of the uterus had predictive value for time to pregnancy, and survival analysis was used to derive a case definition of endomet arthritis based on factors associated with increased time toregnancy.
Journal ArticleDOI
Impact of hyperketonemia in early lactation dairy cows on health and production.
TL;DR: Serum BHBA concentrations at or above 1,200 micromol/L in the first week following calving were associated with increased risks of subsequent displaced abomasum and metritis, and the best threshold for predicting subsequent risk of clinical ketosis from serum obtained during wk 1 and wk 2 postpartum was 1,400 micromols/L.

Neutrophil function and energy status in Holstein cows with uterine health disorders.
TL;DR: In this paper, the authors investigated the associations between peripheral blood neutrophil (PMN) function, energy status, and uterine health in periparturient dairy cows.
Journal ArticleDOI
Prevalence of endometritis and its effects on reproductive performance of dairy cows
TL;DR: Endometritis diagnosed by endometrial cytology late in the voluntary waiting period was highly prevalent and exerted a profoundly detrimental effect on subsequent reproductive performance, making this condition potentially extremely costly to the North American dairy industry.

TL;DR: In conclusion, subclinical endometritis, diagnosed by EC or US, was associated with reduced relative pregnancy rate and no diagnostic criteria based on transrectal palpation of the uterus had predictive value for risk of pregnancy.
