Mastitis is an inflammation of the mammary gland that can result in an elevated somatic cell count (SCC). It is mainly caused by intramammary infections (IMI). Cows with mastitis can have clinical signs (clinical mastitis) or no clinical signs (subclinical mastitis). Because subclinical IMI are the commonest cause of subclinicalRead more

Comparing dairy farm performance and heat stress abatement strategies in the United States using summer to winter ratios (S:W ratio)

Heat stress abatement is a challenge for many producers around the world. Dairy producers could benefit by utilizing a simple metric to measure heat stress abatement strategies with the goal of motivating improvement in heat stress management on farm. The summer to winter ratio (S:W ratio) was developed by ExtensionRead more

The effect of dry period length on milk production, health and fertility in two cow breeds

Dairy cow health and welfare can, with relatively simple and cost-efficient means, be improved by disputing established management practices and make adaptations to the physiology and needs of the modern, high-yielding cow. Presently, it is generally recommended that the dry period covers approximately 8 weeks, but today’s dairy cows areRead more

Evaluation of casein hydrolysate as an alternative dry-off treatment and milk quality management tool in dairy cows

Many cows will experience mastitis during a lactation cycle, with some undergoing recurrent episodes in a single mammary quarter. The initial focus of our research was the effect of intramammary casein hydrolysate (CH) administered to single mammary quarters of dairy cows mid-lactation in comparison with a placebo (P) or noRead more

Antimicrobial consumption on Flemish dairy herds: quantification, associated factors and mastitis management input as a basis for appropriate use

The overall goals of this thesis were to picture the antimicrobial consumption (AMC) on dairy herds in Flanders, to identify associated factors and to explore whether AMC, udder health and milk quality can be influenced by intensive follow up. The first study revealed that the average antimicrobial use was 20.78Read more
