Prevalence of Giardia duodenalis genotypes in pre-weaned dairy calves.
To determine the prevalence of Giardia genotypes in pre-weaned dairy calves, fecal samples were collected from a minimum of 18, 1-7-week-old dairy calves per farm on two farms each in the states of Vermont, New York, Pennsylvania, Maryland, Virginia, North Carolina, and Florida. Samples cleaned of fecal debris and concentrated using CsCl density gradient centrifugation were stained and examined...
متن کاملNutrition and Immunity for Pre-weaned Dairy Calves
Dairy calves are extremely susceptible to gastro-intestinal disease during the pre-weaned period. The risk for enteric disease decreases as the calf ages; therefore, it is important to break the pre-weaned period up into at least 2 distinct phases that likely need to be managed differently, early life (1st and maybe the 2nd week of life) and the remaining time the calf is fed fluid. When a calf...
متن کاملNew insights on ill-thriftiness in early-weaned buffalo calves
AIM The present study was designed to: (1) Investigate the effect of weaning time on various metabolic indices and growth pattern in buffalo calves compared to cow calves under field condition and (2) Shed light on the potential relationship between early weaning, growth metabolites, and suboptimal growth (ill-thrift) in buffalo calves. MATERIALS AND METHODS A total number of 18 neonatal calv...
متن کاملMetaphylactic Use of DRAXXIN (tulathromycin) in Weaned Dairy Calves at High Risk for Infectious Respiratory Disease
• Metaphylactic antimicrobial treatment of weaned dairy calves immediately prior to movement from individual to group housing offers an opportunity to prevent bovine respiratory disease (BRD) in these high-risk animals. • The efficacy of DRAXXIN ® metaphylaxis in high-risk dairy calves was evaluated in 6 controlled research trials conducted in different regions of the US. • A single metaphylact...
متن کاملPrevalence and genotypes of Giardia duodenalis in post-weaned dairy calves.
To determine the prevalence of Giardia genotypes in post-weaned dairy calves, fecal specimens were collected from 3 to 11-month-old dairy calves per farm on two farms in Vermont, New York, Pennsylvania, Maryland, Virginia, North Carolina, and Florida. Specimens cleaned of fecal debris and concentrated using CsCl density gradient centrifugation were stained and examined by immunofluorescence mic...
