Smallholder farming systems in sub-Saharan Africa have undergone changes in land use, productivity and sustainability. Understanding of the drivers that have led to changes in land use in these systems and factors that influence the systems' sustainability is useful to guide appropriate targeting of intervention strategies for improvement. We studied low input Teso farming systems in eastern Ug...

The potential of fallen stock data to monitor the health status of animal populations has been noted in previous studies. However, further research is required to implement these systems for surveillance. This work presents a novel approach to determining the baselines associated with bovine fallen stock, comparing patterns between subpopulations and identifying subpopulations in which an abnor...

Bovine tuberculosis (Mycobacterium bovis) was discovered in northern Michigan white-tailed deer (Odocoileus virginianus) in 1994, and has been known to exist in Michigan cattle herds since 1998. Despite efforts to eradicate the disease in cattle, infection and re-infection of farms continues to occur, suggesting transmission among cattle, deer, or other wildlife reservoirs. The goals of this st...

BACKGROUND Parasitic nematodes are one of the most important causes of production losses in most cattle-producing countries of the world. The aim of the present study is to make a through estimate of helminth and protozoan infection prevalence in dairy cattle around Taiwan. METHODS Coprological techniques, including direct fecal smear, simple flotation, and simple sedimentation, were used to ...

Horizontal transmission is recognized as a major infection route for bovine leukemia virus (BLV), and cattle with high viral loads are considered to be a major infectious source in a herd. However, a correlation between viral loads and the risk of infection has been insufficient to use as a foundation for BLV control strategies. In this report, we examined the epidemiology of BLV infection and ...

A model of the epidemic dynamics of heartwater within a cattle production unit was presented by Yonow et al. (1998). Here, the model is expanded to a region consisting of several farms to study the effect of environmental variability on control strategies. We have shown that: * In a region, where the environment of each farm is modelled with constant epidemiologic parameter values, while the be...

Mitochondrial DNA (mtDNA) sequence data and amplified fragment length polymorphism (AFLP) patterns were compared for the lungworm Dictyocaulus viviparus, a nematode parasite of cattle. Eight individual D. viviparus samples from each of 8 herds in Sweden and 1 laboratory isolate were analysed, with the aim of describing the diversity and genetic structure in populations using different genetic m...

This survey aimed to evaluate the level of lead (Pb) pollution in cattle in the vicinity of the Shiraz oil and petrochemical industries using hair samples. Dairy farms located within 10 km of the Shiraz oil and petrochemical industries were identified and divided into four groups. Farms that were located in the radial zones of 0.5-1.5 km, 1.5-5 km, 5-7 km, 7-10.5 km were considered as groups A,...

Leptospirosis is a zoonosis of worldwide distribution, caused by Leptospira interrogans. It is a well known cause of bovine reproductive losses such as abortion, infertility, stillbirth and birth of weak calves. Inthis research, the relationship between the seroprevalence rate of Leptospira spp. infection and abortion inindustrial dairy farms of Hamedan province, Iran was studied. A total of 80...

Aim: To know the gastrointestinal parasitic infections in cattle of Meghalaya, India. Materials and Methods: A total of 676 faecal samples of cattle were collected for a period of two years from different organized cattle farms of Meghalaya for detection of gastrointestinal parasitic infections, using standard techniques. Results: Out of 676 faecal samples examined, 191 (28.25%) faecal samples ...
