This study determined association of some morphometric characteristics of udder with mastitis in dairy cattle. For this purpose; 100 animals each negative and positive for mastitis by California Mastitis Test and bacteriology, were selected from amongst those brought for slaughter at Faisalabad abattoir. Morphometric observations on udder were recorded pre-slaughter; whereas, samples from mamma...

1. [U-14C]glucose was infused intravenously into conscious lactating goats exposed to thermoneutral or cold environments for a total of 24 h. The irreversible loss of glucose from the whole body and uptake of glucose by the mammary gland was measured and glucose utilization in the udder was studied by measuring the incorporation of radioactivity into carbon dioxide in mammary venous blood, into...

The objective of this study was to determine the effect of tail docking on somatic cell count (SCC), intramammary infection (IMI), and udder and leg cleanliness in commercial dairy herds. Lactating dairy cows (n = 1250) from eight Wisconsin farms were blocked by farm and randomly allocated to tail docked (D) or control (C) groups. Milk samples, somatic cell counts, and hygiene scores were colle...

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...
