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...

Understanding the intentions of dairy farmers towards mastitis control is important to design effective udder health control programs. We used the Theory of Planned Behavior (TPB) to explore the intentions of North-Western Ethiopian dairy farmers towards implementing non-specified mastitis control measures (nsMCMs) and towards implementing 4 specific MCMs. Face to face interviews were held with...

background:mastitis is the most economically importantdisease in dairy industry worldwide. bulk tank milk (btm)analysis has been suggested for monitoring the udder healthstatus at herd level. objectives: a cross-sectional study wasconducted to evaluate udder health status in 15 holstein dairyfarms located in qom province. methods: bulk tank somaticcell count (btmscc) was analyzed using opto-flu...

BACKGROUND Studies outside the Nordic countries have indicated that subclinical mastitis (measured by milk somatic cell count or the California Mastitis Test), intramammary infections (IMI), or blind quarters in beef cows may have negative effects on beef calf growth. Knowledge on prevalence of such udder health problems in Swedish beef cows is scarce. Therefore, the main aim of this study was ...

The main purpose of this article is to describe interaction between physiology of lactation and milking machine. This is important in order to avoid bad influ­ ences (such as: high somatic cell count (SCC), mastitis, etc.). The paper is divided into two parts: The anatomy part describes udder characteristics needed for healthy udder and high milk yield. The milking machine part describes milkin...

The introduction of the “Milking Protocol” on farm is a mandatory condition for preventing intramammary infections, maintaining cows' productivity, and improving milk quality. Treating udders with hygiene products an effective preventive udder care measure in most dairy herds. choice antiseptic agent health should be based its proven effectiveness, which necessary to register drug as veterinary...

Effect of three hygienic conditions (T1washing and disinfection of udder and teats, milker hands, and a sanitary rinse of milking pails using calcium hypochlorite solution with 200 ppm Cl; T2washing of udder and teats, milker hands and milking pails with normal water; and T3without any kind of preparation of udder and teats, milker hands and milking pails) before milking were studied. Fifteen “...

Cows’ infrared radiation temperature study was carried out at experimental cowshed (120 cows) of Estonian University of Life Sciences. Thermal image scanner Fluke TiS was used for obtaining 640×480 pixels thermal images with resolution of 0.1°C. The temperature distribution pattern of different parts of cow’s body was estimated and analysed with SmartView software. Special attention was paid to...

Infection of the mammary gland with environmental bacterial pathogens is the most significant udder health problem facing the dairy industry in North America. Forty years ago, Neave et al. (1966) stated that the rate of new intra-mammary infection is related to the number of bacteria that the teat end is exposed to, and several studies have made associations between clean housing, clean cows an...

Cattle comfort is one of the main factors which influence profitability of dairy farms due to its association with involuntary culling, cow longevity, and productive life. Productive life has been defined as the number of lactations a cow completes before she is culled. A productive cow that remains longer in a farm allows for fixed and variable costs to be diluted. Furthermore, fewer replaceme...
