A prospective follow up study was conducted in Addis Ababa town attends on different selected farms for fifteen months from January 2015 to April 2016. The aims of this study were to determine the current status of parturient paresis, associated risk factors, and to estimate the economic loss of parturient paresis that is attributed in dairy herds. Parturient paresis is a condition of third to ...

In dairy cattle, bedding and its management contribute predominantly to the comfort of cow, udder health milk quality. The aim study is assess effect different materials such as concrete floor, rubber mats, coir pith dried solid manure on hygiene yield in crossbred cows. Twenty-four cows with six animals each group were selected for one lactation period spread over three seasons. control (T1) w...

The aims of the present study were (1) to evaluate the influence of using mobile (n=47) or fixed (n=45) milking machines in Azorean herds on the apparent prevalence of several milk pathogens in bulk tank milk (BTM) and (2) to determine whether separated subclinical mastitic cows can serve, in real time, as predictors of milk pathogen prevalence for the remaining animals at the herd level. The u...

Oral health includes freedom from disease in the gums, the mucosa and the teeth. There has been a striking reduction in dental caries and periodontitis in industrialized countries, although the proportion with severe disease has remained at 10-15%, and the prevalence increases in less developed countries. If left untreated, these diseases may lead to pain, and impaired quality of life and nutri...

Bovine mastitis remains the most common and costly disease of dairy cattle worldwide. A complementary control measure to herd hygiene and vaccine development would be to selectively breed cattle with greater resistance to mammary infection. Toll-like receptor 1 (TLR1) has an integral role for the initiation and regulation of the immune response to microbial pathogens, and has been linked to num...

The objective of this study was to characterize the clonal profile, virulence factors and antimicrobial resistance, particularly oxacillin resistance, of Staphylococcus aureus isolated from sheep milk. Milk samples were collected from all teats for the California Mastitis Test (CMT), somatic cell count, identification of S. aureus, investigation in these strains of genes encoding toxins (sea, s...

The objective of this research project was to ascertain the hygiene quality and some physicochemical properties of milk obtained from mares of the Wielkopolska breed at different periods of lactation. Colostrum and milk for analyses were collected on days: 1, 2, 3, 4 and 5 of lactation and afterwards at 15-day intervals up to day 150 of lactation. A significant influence of lactation on levels ...

This study examines the impact of traditional hygienic milking practices employed by rural small-scale dairy farmers on quality raw milk. While advancements in technology have revolutionized milk production methods for both small- and large-scale farmers, producers, particularly countries like Zimbabwe, continue to rely heavily hand as their primary method harvesting. To investigate this issue,...
