AI Article Synopsis
- The study focused on the seroprevalence of melioidosis in dairy cattle in Chiang Mai Province using the indirect hemagglutination antibody method, testing 253 samples out of 8,688 cattle.
- The seroprevalence was found to be 2% at a 1:40 cut-off value, with a confidence interval suggesting a range between 0.3% to 3.7%.
- This relatively low prevalence in Chiang Mai contrasts sharply with higher prevalence rates reported in northeastern Thailand, highlighting differences in disease endemism across regions.
Article Abstract
The seroprevalence of melioidosis in dairy cattle in Chiang Mai Province was investigated using of the indirect hemagglutination antibody (IHA) method. Two hundred and fifty-three samples were tested for serum antibodies to Burkholderia pseudomallei. The samples were from a total population of 8,688 dairy cattle in the province; random sampling, stratified by the location of cattle, was used. The seroprevalence was determined as 2% at 1:40 cut-off value, which was estimated to equate to 0.3% to 3.7% (95% CI). This report of relatively low disease prevalence in the animal population corresponds to other prevalence studies of the agent in the environment and the human population in the region. The prevalence is markedly different to that reported from northeastern Thailand, where the disease is highly endemic.

Vitamin D is essential for cattle and can be synthesized in the skin under ultraviolet irradiation. This study investigated the effects of narrow-band UV-B irradiation during automatic milking on blood vitamin D concentration and the influence of hair and black skin areas on cutaneous vitamin D synthesis in Holstein Friesian cows. Fifty-one cows were stratified by milk yield, days after calving, and percentage of black skin, then divided into three groups: shaved and irradiated (80 J/m), unshaved and irradiated (129-305 J/m), and a control group.

Brucellosis is a bacterial disease of many domestic and wild animals with great economic and public health importance. Although it has a major constraint in dairy production, comprehensive information regarding the epidemiology of brucellosis in dairy herds is limited. Besides, evaluating the dairy farmers' knowledge, attitude, and practice (KAP) regarding brucellosis is crucial for generating information that can enhance control programs and public health interventions.

Although peritonitis is highly prevalent in cattle, there have been only limited studies on the pathology of this condition. We describe the gross and histological aspects of primary and secondary peritonitis in cattle based on necropsy reports of 46 cases. Twenty-six were female (26/46; 56.

Microbiota in the gastrointestinal tract (GIT) consisting of the rumen and hindgut (the small intestine, cecum and colon) in dairy calves play a vital role in their growth and development. This review discusses the development of dairy calf intestinal microbiomes with an emphasis on the impact that husbandry and rearing management have on microbiome development, health and growth of pre-weaned dairy calves. The diversity and composition of the microbes that colonize the lower GIT (small and large intestine) can have a significant impact on the growth and development of the calf, through influence on nutrient metabolism, immune modulation, resistance or susceptibility to infection, production outputs and behaviour modification in adult life.

Periparturient dairy cows experience metabolic adaptations to prepare for increased nutrient requirements of the fetus and the onset of lactation. Adaptations include increased peripheral tissue insulin resistance, which can be evaluated experimentally using intravenous glucose tolerance tests (IVGTT). The objective of this study was to determine if prepartum skeletal muscle reserves and supplementation of branched-chain volatile fatty acids (BCVFA) in the prepartum period affected blood glucose, β-hydroxybutyrate (BHB), and insulin concentrations 2 wk prepartum and 1 wk postpartum utilizing an IVGTT.
