In order to get a reliable estimate of brucellosis prevalence in Eritrean dairy cattle, a cross-sectional study was carried out in 2009. The survey considered the sub-population of dairy cattle reared in modern small- and medium-sized farms. Samples were screened with the Rose Bengal test (RBT) and positive cases were confirmed with the complement fixation test (CFT). A total of 2.77%(417/15 04...

This article presents suggestions toward safer animal handling utilizing the results of a qualitative study of women dairy farmers in Finland. A major proportion of injuries (43%) occur in livestock-related work in Finnish agriculture. An even greater proportion of women's farm injuries (77%) is related to animals. We investigated the working conditions often women dairy farmers. Data were coll...

The onset of tetany, when dairy cattle have insufficient magnesium, has a huge impact both economically and on animal welfare. We have previously adapted a model of magnesium dynamics in sheep (Robson et al. 1997) for use with dairy cattle as an aid to understanding aspects of magnesium metabolism which influence the risk of animals contracting tetany (Bell et al. 2005). To estimate this risk i...

were passing meat inspection. Meat inspectors were requested to submit lymph nodes that appeared abnormal as to size, color, or consistency. A total of 2843 dairy animals3 and 6791 beef animals was inspected on collection days. Lymph nodes were submitted from 736 cattle. Four dairy cattle were found to have malignant lymphoma following the histopathologic study. Two of these cows with extensive...

The objective of this study was to identify claw lesions causing clinical lameness in lactating Holstein Frisian (HF) crossbred cows in dairy cattle. Seventy dairy farmers were interviewed at the monthly meetings of Progressive Dairy Farmers Association of Ludhiana, Punjab, India. Ten dairy farms were randomly selected as per probability proportional to size and a total of 450 lactating HF cros...

Cryptosporidium parvum oocysts were detected in feces of dairy calves raised in Rio de Janeiro State and the risk factors involved in the infection were determined. A hundred calves aging up to 12-month-old from 13 dairy farms were sampled. Polymerase chain reaction was used to detect the presence of oocysts. The zoonotic C. parvum species was detected in 45% animals. Statistical risk factors a...
