A cross sectional study of prevalence and risk factors associated with subclinical mastitis and intramammary infections, in dairy herds linked to milk collection centers in Rwanda

Subclinical mastitis: Prevalence and risk factors in dairy cows in East Java, Indonesia

“…In contrast, a previous study showed that cows with an SCM history and reproductive disorders are more likely significantly associated with SCM prevalence [35,36]. This study showed that analyzing the breed as a factor for all of the farmers raises FH, and this breed has been reported to have a higher OR (OR=5.1) than other breeds [19,35]. The floor material of the cage was also reported to significantly affect the risk of SCM, especially the floor with spilled feed showed a prevalence of 64.2% [34].…”

“…Significant differences were noted in the impact of the appearance of mastitis diseases. Other management practices that are also significant for SCM are lactation stage, breed, calf suckling, and parity with strong correlation [19]. Decreased milk production can occur in cows identified with SCM in the 1 st month of lactation and will continue through the entire lactation period.…”

“…); fungi (Penicillium spp., Aspergillus spp., Alternaria spp., Fusarium spp., Absidia spp., and Aureobasidium pollulans), yeast (Candida etchellsii, Candida albicans, Candida guilliermondii, Candida parapsilosis, Candida kefyr, Candida famata, Candida krusei, Chrysosporium spp., Geotrichum candidum, Trichosporon spp., Rhodotorula spp., and Saccharomyces cerevisiae), and algae (mostly Prototheca zopfii and in small amounts of Prototheca wickerhamii) [13][14][15][16]. The incidence of SCM in Indonesia and several developing countries is relatively high, that is, Central Java (46.41%), Boyolali Indonesia (65%) [17,18], Iran (67.20%) [14], Rwanda and North-West Ethiopia (62%) [19], and Kenya (50.9%) [20]. The incidence of SCM in East Java was reported to be approximately 70% in 2018 and increased to 85% in 2019 [21][22][23].…”

MILK Symposium review: Microbiological quality and safety of milk from farm to milk collection centers in Rwanda

“…The MCC technicians and milk transporters guided the research team to enlist farmers located in all provinces (east, south, west, and north) relative to the MCC. Dairy farmers included in the study per MCC corresponded to farmers whose lactating cows were previously screened for subclinical mastitis and described in a study by Ndahetuye et al (2020). Based on these estimations, the number of dairy farmers included in the study were 50 in MCC1, 14 in MCC2, 64 in MCC3, 55 in MCC4, 58 in MCC5, 56 in MCC6, 45 in MCC7, and 64 in MCC8.…”
