Genetic evaluation of clinical mastitis traits in Holstein cattle
udder health mastitis resistance genetic parameters genetic trend
2018/11/23
The results obtained from different models for predicting breeding values for clinical mastitis (CM) in Holstein cattle were compared. CM was recorded in 30 882 lactations of 12 793 cows in 8 herds fr...
L-selectin gene polymorphism and its association with clinical mastitis, somatic cell score, and milk production in Polish Holstein-Friesian cattle
SELL udder inflammation milk production traits cows
2018/11/23
Bovine mastitis is a widespread disease of the mammary gland, highly contributing to the increase in veterinary costs in dairy industry. In the present study, the genetic polymorphism within bovine L-...
Therapeutic effects of a combined antibiotic-enzyme treatment on subclinical mastitis in lactating dairy cows
mastitis Staphylococcus aureus biofilm enzyme-antibiotic treatment genomic DNA ica genes
2016/6/3
The objective of this study was to evaluate a combined antibiotic-enzyme therapy for Staphylococcus aureus mastitis and biofilm formation. A total of 141 cases of S. aureus chronic mastitis from three...
Factors in Dry Period Associated with Intramammary Infection and Subsequent Clinical Mastitis in Early Postpartum Cows
Dry Period Clinical Mastitis Intramammary Infection
2016/5/20
The objective of this study was to determine cow characteristics and farm management factors during the dry period associated with early postparturient intramammary infection (IMI) and subsequent clin...
Goat mastitis detection using daily records of milk conductivity: comparative results of different algorithms
intramammary infection gland measurements on-line
2015/7/2
Milk electrical conductivity is employed for mastitis detection in cows due to its automation, low cost, and infection detectability at early stage. Nevertheless, the number of publications about its ...
Comparative proteomics analysis of plasma proteins during the transition period in dairy cows with or without subclinical mastitis after calving
dairy cow plasma proteome periparturient
2015/6/23
The transition period is the most critical time of the cow’s lactation cycle that is associated with
the onset of mastitis. In this study, changes of plasma proteins in cows (n = 12) with or without...
Polymorphisms in CGIL4, breeding value for somatic cell count and resistance to mastitis
mastitis CGIL4 somatic cells Czech Simmental cattle German Holstein cattle
2015/6/9
The relationship between a potential marker for mastitis, CGIL4, and the breeding value for somatic cell count (SCC) was analysed in a panel of Czech Simmental and German Holstein sires. Genotyping wa...
The association between the somatic cell count and isolated microorganisms during subclinical mastitis in heifers in Jordan
subclinical mastitis (SCM) somatic cell count
2015/5/25
All isolates except for the CNS group exhibited strongly elevated SCC
(> 1 × 106
cells/ml). However, the coagulase-negative Staphylococci did not have a distinct pattern with respect
to SCCs. The...
The association between the somatic cell count and isolated microorganisms during subclinical mastitis in heifers in Jordan

Mastitis is an important cause of early culling of dairy heifers. The aims of this study were to identify microorganisms that cause subclinical mastitis (SCM) in Holstein heifers in northern Jordan, t...
Prevalence of mastitis pathogens in milk from clinically healthy cows
mastitis bovine intramammary IMI etiology epidemiology macrorestriction
2015/4/16
A total of 669 individual cow milk samples originating from asymptomatic cows from 16 dairy farms were examined for the presence of microorganisms with the potential to cause mastitis. Coagulase-negat...
Dynamics of milk leukocytes in response to intramammary infusion of amoxicillin plus sulbactam during bovine subclinical mastitis
