Intramammary infections in cattle resulting in mastitis have detrimental effects on cows' well-being, lifespan and milk production. In the host defense against S. aureus mastitis antibodies are thought to play an important role. To explore potential ways to increase antibody titers in the bovine mammary gland the effects of various adjuvants on the magnitude, isotype, and neutralizing capacity ...

Clostridium botulinum is an anaerobic spore-forming bacterium prevalent in the environment, and causes botulism in man and animals via toxins. Dairy cattle may be contaminated or infected by feed, water or other environmental factors. Milk may also carry the pathogen. Hence, milk and udder samples need to be tested. The number of clinical cases of bovine botulism in Germany has been increasing ...

A new breeding value estimation procedure for mastitis traits has been implemented in the Dutch/Flemish dairy genetic evaluation. This breeding value estimation uses incidences of subclinical mastitis together with five indicator traits derived from test day somatic cell counts to predict the breeding value for resistance against subclinical and clinical mastitis (SCM and CM, resp.). The mastit...

we reportedhere data from a productivity veterinary service that was participatory planned and delivered on farms at the kanihari union belongs to mymensingh district of bangladesh. we used a set of five forms and a breeding calendar on farm visit once in a month to guide service delivery and acquisition of data and to keep the records on general cattle health, reproduction, udder health and fe...

The role of Staphylococcus aureus and coagulase-negative staphylococcal exosecretions in bovine udder infection was tested by monitoring the cows' response to in vivo inoculation of bacterial exosecretions into udder quarters. Twenty Israeli-Holstein dairy cows were included in the study; two or three of the udder quarters of each cow were intracisternally inoculated with 0.04-0.05 mg/quarter (...

Article history: Received 23 April 2010 Received in revised form 9 September 2010 Accepted 16 September 2010 The aim of this experiment was to study the effects of six different management routines at the time of farrowing on latency to first suckle, heat loss, weight gain and postnatal mortality. A total of 872 piglets from 67 loose housed sows in a commercial pig unit were subjected to one of...

Experiments were designed to investigate the suitability of a combination of a short manual teat stimulation with a short latency period before teat cup attachment to induce and maintain oxytocin release and milk ejection without interruption. In Experiment 1, seven dairy cows in mid lactation were manually pre-stimulated for 15, 30 or 45 s, followed by either 30 s or 45 s of latency period. It...

The aim of this study was to develop a methodology to measure sow udder conformation to use in studying the correlation between udder traits and piglet survival, health and performance. The steps in the investigation were (i) to assess the repeatability of measures, (ii) to determine if there was an important difference between the two sides of the udder, (iii) to assess the extent of variation...

Worldwide, programs to control mastitis are implemented using different strategies to reach farmers. Even though education materials and best practices may be technically optimal, they need to be used to be successful. Thus, effective communication with farmers is essential in order to change their behavior and to improve their farm management. During a Dutch national mastitis control program, ...

The objective of this study was to evaluate the morphometric and reproductive traits of indigenous dairy goat types. It was conducted in three districts (Ebnat, Gonji-kolela and Farta) based on the agro-ecological differences, goat population potentials and experience of the farmers using goat milk. Semi-structured questionnaires, field observations, morphological and reproductive trait measure...
