conclusions iglm should be considered as one of the differential diagnoses when granulomas are encountered in breast fnac and biopsy. a definitive diagnosis of iglm can be made by identifying its characteristic histomorphology and ruling out other causes for granulomatous inflammation. an exact diagnosis is essential since the treatment for different granulomatous conditions of the breast varie...
Research emphasis has been placed on heifer development strategies in recent years, comparing traditional, more intensive systems to more extensive systems using less feed and relying on compensatory gain to reach a target BW. Recent research has indicated that developing heifers to a lighter target BW at breeding (i.e., 50 to 57% of mature BW compared with 60 to 65% BW) reduced development cos...
thirtyfrieswal lactating cows were screened for clinical and subclinical mastitis and subsequently classified into healthy, subclinically affected and clinically affected groups each group comprising of 10 cows. polymorphism of cow lactoferrin (ltf) gene promoter was determined by polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp). the results showed that lft gene pro...
The aim of the present study was to compare the occurrence and duration of clinical mastitis in different seasons, stages of lactation period and parities in a Holstein dairy farm in Iran. A retrospective epidemiological survey from April 2005 to March 2008 was conducted on 884 clinical mastitis cases of 7437 lactations. Data of each case including calendar-date of mastitis onset, days in milk ...
A cross-sectional study to investigate prevalence, seasonal prevalence and causative agents of clinical and subclinical dromedary camel mastitis in Saudi Arabia (KSA) was conducted. The prevalence of acute mastitis was 3.6% and of chronic mastitis was 2.2%. Physical tests, California mastitis test (CMT) and somatic cell count (SCC), were done in normal and infected milk specimens to draw a bord...
A 10-month-old Japanese black heifer was diagnosed as having an intra-abdominal cyst using computed tomography (CT). Through a posterior ventral midline incision, the cyst was removed, and the heifer completely recovered after the surgery. CT scans enabled detection of the intra-abdominal cyst and measurements of the diameter of the cyst before the surgery.
Bovine mastitis, which is an inflammation of the mammary gland frequently resulting from bacterial infection, causes the majority of economic losses to the dairy producers. The prevalence of mastitis in dairy cattle is relatively high. Bovine mastitis can be classified based on clinical futures as clinical or subclinical. Both forms produce significant economic losses due to rejected milk, degr...
Coliform mastitis is tremendously important to the dairy industry for several reasons. First, it has become the predominant form of clinical mastitis and current management practices favor an increase in incidence. Second, coliform organisms cause some of the most severe cases of clinical mastitis. Third, as present trends in the dairy industry of increasing milk quality continue, environmental...
segment of the integrated management program in an efficient beef cow production system. The main objective should be to develop an adequate number of heifers to a point where they reach puberty and are cycling regularly at the start of the breeding season. In addition, they should have adequate pelvic area to deliver a reasonable size calf unassisted. Because of her increased nutritional needs...
Coagulase-negative staphylococci (CNS) are a common cause of subclinical mastitis in dairy cattle. The CNS inhabit various ecological habitats, ranging between the environment and the host. In order to obtain a better insight into the host response, an experimental infection was carried out in eight healthy heifers in mid-lactation with three different CNS strains: a Staphylococcus fleurettii s...
