Udder diseases in dairy cows — field observations on incidence, somatic and environmental factors, and control

Abstract

The present study was carried out at the Department of Animal Hygiene, College of Veterinary Medicine, Helsinki

Nordic dairy farmers’ threshold for contacting a veterinarian and consequences for disease recording: Mild clinical mastitis as an example

“…The intent to take a milk sample and send for analysis in FI was very high, and can be expected to represent the action taken in over 60% of MCM cases. This finding agrees with a previous study (Saloniemi, 1980) stating that approximately 65% of Finnish clinical mastitis cases were treated with phone prescription drugs. Whether such an MCM case in FI will become a recorded case of mastitis depends on whether the milk test result shows an indication for medical treatment.…”

“…In contrast to the other countries, the common practice for dairy producers in FI is to take a milk sample from the cow with MCM and send for bacteriological analysis (Saloniemi, 1980). When the results are ready, the farmer contacts the veterinarian for consultation and treatment may be prescribed without a physical examination of the cow by the veterinarian.…”

Tramped Teats – Clinical Mastitis Disease Complex in Tied Cows. Environmental Risk Factors and Interrelationships with Other Diseases

“…For tramped teats and udder injuries the effect of parity was similar for both systems but a larger increase in risk of clinical mastitis with parity was found in farms with liquid manure system. These results are in agreement with Bakken (1982), Curtis et al (1985) , , Pearson & Mackie (1979), Saloniemi (1980), all indicating increased incidence of mastitis and /or other udder problems with age.…”

“…Ekesbo (1966), Grommers et al (1972) and Karlsson & Gustafsson (1977) have shown that environmental factors such as stall length, amount and type of bedding used, construction of the feed barrier and other factors play an important role with respect to udder health. The increase in risk of mastitis with age was shown by Bunch et al (1984), and Saloniemi (1980). The association of clinical mastitis with teat injuries was reported by Ekesbo (1966), Pearson & Mackie (1979) and Sieber & Farnsworth (1981), with veter inary assisted dystocia and retained placenta by 01 tenacu et al (1989), with milk fever by Cur tis et al (1985), and with ketosis by .…”

Retrospective study of clinical cases presented at veterinary hospitals in Khartoum State, Sudan

“…He mentioned that there were many risk factors associated with occurrence of bovine mastitis in dairy farms such as age, parity, stage of lactation and lesions on the udder as well as general hygienic conditions in the farms. Moreover, Saluiemi (1980) reported that it there was mastitis problem with cows in a loose horse, the cause is as a result of poor milking hygiene or milking machine. Our results regarding foot and mouth disease (FMD) is in agreement with Niema (2005) who found 4 serotypes in serum samples from Table 7.…”
