Mycoplasma bovis (M. bovis) is a highly infectious pathogen of cattle causing pneumonia, polyarthritis, otitis, and less frequently, subcutaneous abscesses, abortions and meningitis. Ineffective drugs treatments, culling of infected cows and loss of milk production can lead to significant economic loss on dairy farms. The early detection of cows excreting M. bovis bacteria to prevent mastitis o...

Profitability of different grouping criteria was simulated in a dairy farm with 153 lactating cows that were divided into three groups of high (79), medium (40) and low (34) cows based on the milk records. Animals were reassigned to the new groups based on the following criteria using a decision support tool and the same three groups scenario: fat corrected milk 4%, days in milk (DIM), dairy me...

backgrounds and aims: healthy milk and dairy products are important in human nutrition  because of the high value of the food. contaminated raw milk is the mainly way of transmition of brucellosis to humans.unpasteurized milk and dairy products can contagion to human and cause mallta fever. so brucellosis is an important zoonotic disease in human and animals especially domestic animals. the aim...

The major problems for the dairy practices in the tropical country are low milk yield and short lactation period of either pure exotic or crossbred dairy cattle. Many factors affect milk production in dairy cattle in tropical areas including high environmental temperature and humidity, lower genetic potential for milk production in indigenous cattle and inadequate supply of food during the dry ...

monthly and seasonal concentrations of milk protein and urea and their relationships were investigated in 614 milk samples from 61 industrial holstein dairy herds in urmia, iran. milk samples were prepared monthly interval up to 12 months. the amount of 10 ml milk was prepared from each dairy herd when they were delivering to the milk factory. milk protein and urea concentration was evaluated b...

the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...

BACKGROUND Observational studies, mainly from Western populations, suggest dairy consumption is inversely associated with adiposity. However, in these populations the intake range is limited and both diet and obesity may share social patterning. Evidence from non-Western developed settings with different social patterning, is valuable in distinguishing whether observed associations are biologic...

has been a hotly debated issue in the US. The initial issue was the effect of drugs, chiefly antibiotics, on cheese manufacturing processes. Reports in the press highlighting contamination of milk and other dairy products with antibiotics and other animal drugs quickly raised the issue of food safety and resulted in the intervention of governmental agencies regulating the use of animal medicati...

Lameness of dairy cattle is an economic and welfare issue. It is the third most important health related economic loss facing the dairy industry, following fertility and mastitis. Most economic loss due to lameness results from costs of premature culling, veterinary treatment, increased labor, discarded milk, prolonged calving interval, and reduced milk production (Kossaibati and Esslemont, 199...

SURÝNEK JAKUB, VRTKOVÁ IRENA, KNOLL ALEŠ. 2016. Mycoplasma bovis Was not Detected in Milk from Dairy Cattle in the Czech Republic. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 165–168. The aim of this study was to screen selected Czech dairy cattle farms for presence of Mycoplasma bovis. Between 2012 and 2014, 160 individual samples of cow milk, 60 colostrum sa...
