Schmallenberg virus (SBV), an orthobunyavirus discovered in European livestock in late 2011 for the first time, causes premature or stillbirth and severe fetal malformation when cows and ewes are infected during pregnancy. Therefore, cattle of two holdings in the initially most affected area in Germany were closely monitored to describe the consequence for fetuses and newborn calves. Seventy-on...

This article shows the results of studies in course which a comparative aspect LEP polymorphism was studied subpopulations Holstein dairy cattle cows with fatty hepatosis and healthy animals. is first time such are being conducted. In this case, hepothesis about relationship genetic markers, particular leptin gene, risk developing progression liver disease model when determining frequency occur...

BACKGROUND The mastitis subclinical and clinical in cows caused by fungi has been increased specially by yeast of the genus Candida. OBJECTIVE To identify what yeasts were present in milk samples obtained from mammary glands of healthy cows, and others suffering subclinical or clinical mastitis. METHODS From a total of 1,095 milk samples 342 were from mammary glands of healthy dairy cows, 3...

This study identified differences in plasma metabolites among three groups of dairy cows: type I ketotic (K1), type II ketotic (K2), and healthy control cows (C). 50 cows with two or three parities were selected at 7–28 days postpartum. Cows were classified as type I ketotic (K1, 20 cows), type II ketotic (K2, 20 cows), or healthy control cows (C, 10 cows). Plasma metabolomic profiles were anal...

Effects of Monensin on Dry Matter Intake, Milk Production and Healthy Transition Holstein Dairy Cows

Of the acute respiratory viral infections in farms of Udmurt Republic, parainfluenza-3, syncytial infection, infectious rhinotracheitis, diarrhea are most common. For prevention these cattle diseases, inactivated combined vaccine Kombovak and R. is used. Despite widespread use this vaccine, there an ambiguous situation UR percentage ARVI incidence extremely variable. Along with general economic...

We reportedhere data from a productivity veterinary service that was participatory planned and delivered on farms at the Kanihari Union belongs to Mymensingh District of Bangladesh. We used a set of five forms and a breeding calendar on farm visit once in a month to guide service delivery and acquisition of data and to keep the records on general cattle health, reproduction, udder health and fe...

In Black-and-White cattle, polymorphism of blood leukocyte acid phosphatase (AcP) is determined by a pair of autosomal alleles. Blood leukocyte AcP polymorphism exhibits a correlation with the white cell composition and the granulocyte metabolic efficiency in clinically healthy animals. The aim of the study was to determine the relationship between the AcP polymorphism and the lymphocyte prolif...

A bovine-specific cDNA microarray system containing 721 unique leukocyte expressed sequence tags (ESTs) and amplicons representing known genes was used to compare gene expression profiles of peripheral blood mononuclear cells (PBMCs) from clinical and subclinical Johne's disease-positive Holstein cows (n = 2 per group). Stimulation of PBMCs from clinically infected cows with Mycobacterium parat...

The objective of this study was to investigate the relationship between prepartum feeding behavior, measured as time spent feeding per day, and periparturient health disorders, milk yield, milk composition, and milk somatic cell count in Jersey cows. Pregnant Jersey cows were marked with unique alphanumeric symbols and were moved into a prepartum group 4 weeks prior to their expected calving da...
