During recent years in Denmark higher rates of antibodies to Coxiella burnetii have been detected in animals and humans than previously reported. A study based on bulk tank milk samples from 100 randomly selected dairy herds was performed to estimate the prevalence and geographical distribution of antibody positive dairy herds. Using the CHEKIT Q-Fever Antibody ELISA Test Kit (IDEXX), the study...

The efficiency of feed utilization on dairy farms can be influenced by a variety of practices that are beyond the scope of this paper, including many aspects of the harvesting, storage, mixing, and delivery of feed components, as well as the grouping of animals according to nutritional needs. Two practices that will be addressed are: 1) improvement of the biological efficiency of lactating cows...

Genetic improvement programs have done a great job selecting animals with superior genetics for milk production. Selection with emphasis on milk production is generally recognized as the single most important objective of breeding programs in dairy cattle worldwide. As a result of this improvement, the dairy cow has changed significantly over the past 7 decades with a remarkable increase in mil...

Dairy cows are exposed to numerous hematological and biochemical changes, particularly in late gestation and early lactation. Various factors influence a metabolic profile in animals. Reliable indicators of metabolic profile and health status of dairy cows in peripartum period are haematological and biochemical parameters. A transitional period in dairy cows is followed by physiological, metabo...

Results from the USDA:APHIS:VS National Animal Health Monitoring System (NAHMS) Dairy 2002 survey reported that approximately 5% of dairy cows die, on-farm, across the country each year. This is a very high death rate compared with that of beef cows or feedlot animals, where annual death rates were estimated at 1 to1.5%. In the NAHMS survey unknown reasons accounted for the largest percentage (...

Superior germplasm, better nutrition strategies, health care facilities and improved dairy husbandry practices have boosted milk yield its quality with a rapid rate. Per cow productivity has risen up sharply considerable increase in the population of animals. Recent era witnessed extension large farms around world. Demand for high increased quantity is prime concern all farms. With an size anim...

This review paper preSents information on the nutritional and management factors that can predispose dairy animals to laminitis. The suggestions regarding various feeding and management practices that may help in preventing laminitis are also discussed. Lameness in dairy animal is a ~rious problem as it cauSes significant economic loss todairy farmers. The outbreak of laminitis can occur at any...

A cross-sectional survey was carried out in ten states in Sudan to determine seroprevalence and to assess risk factors associated with Akabane virus (AKAV) infection in dairy herds. Serum samples were collected from a total of 361 dairy cattle and tested for antibodies against AKAV using ELISA. The prevalence rates of AKAV antibodies in cattle varied between 69.6% in Khartoum state and 3.3% in ...

Background and Objective: As the most important human food source, milk and dairy products may lead to infectious diseases due to non-compliance with health standards. Brucellosis is one of the critical zoonotic diseases that affect the human population. Humans are usually infected by Brucella spp. via contaminated milk and dairy products and direct contact with infected animals. Methods: This...
