AbstractBovine mastitis is an important animal production disease that affects the dairy industry globally. Studies have estimated the prevalence of this disease in approximately 30% of African countries, with the highest prevalence found in Ethiopia. This is despite the wide cattle distribution in Africa, and the largest number of dairy farms and herds in countries such as South Africa, Kenya and Uganda. Furthermore, the estimated financial losses due to direct and indirect impacts of bovine mastitis are lacking in this continent. Therefore, intensive research efforts will help determine the

One of the most important problems in milk production, causing great economic loses is certainly mastitis. In order to minimize economic losses from mastitis dairy farms introduce different mastitis management programs. These programs include mastitis therapy and prevention. In mastitis control prevention is most important and when mastitis occurs cost of therapy and milk discharge is very important. In our study we examined cost of mastitis treatment and milk loss in different mastitis management programs. We concluded that most costly are mastitis caused by specific pathogens. Cost of milk l

Bovine mastitis remains a primary focus of dairy cattle disease research due to its considerable negative economic impact on the dairy industry. Subclinical mastitis (SCM), commonly caused by Staphylococcus aureus, lacks overt clinical signs and the diagnosis is based on bacteriological culture and somatic cell counts of milk, both of which have limitations. The main objective of this study was to identify, characterize and quantify the differential abundance of milk whey proteins from cows with S. aureus SCM compared to whey from healthy cows.

The goal of this research was to develop a stochastic Monte Carlo simulation model to support decisions around treatment of chronic subclinical mastitis caused by Streptococcus uberis. Factors in the model included the probability of cure after treatment, probability of the cow becoming clinically diseased, transmission of infection to other cows, and physiological effects of the infection.

Goat milk ranks fourth in terms of global milk production and lately it has become increasingly popular among consumers. Unfortunately, mastitis is one of the most common diseases that affects dairy goats, with serious economic consequences and food safety matters. The prevalence of clinical mastitis is lower than 5% and the main aetiological agent is S. aureus. On the other hand, the prevalence of subclinical mastitis is between 5-30%, with coagulase negative staphylococci (CNS) representing the most often isolated microorganisms.The aim of this paper is to highlight the main aspects regardin

As of other dairy animals, dromedary camel could be affected by mastitis, a complex disease occurring worldwide among dairy animals, with heavy economic losses largely due to clinical and subclinical mastitis. Yet, little is known about the occurrence and potential risk factors exposing to lactating camel mastitis in Ethiopia. Consequently, a cross-sectional study was carried out from November 2018 to April 2019 so as to determine the prevalence, associated risk factors, and major bacterial pathogens causing mastitis in traditionally managed lactating camels in Gomole district of Borena Zone.

Purpose: Mastitis is an inflammatory disease condition of udder affecting milk production negatively and having a serious impact on the economy of dairy enterprises. It is considered to be the most costly disease of dairy animals and losses mainly occur through discarded milk, reduction in milk yield, premature culling of animals and replacements. It is usually caused due to the effects of infection by bacterial or mycotic pathogens. Pathological changes to milk-secreting epithelial cells due to the inflammatory processes often bring about a decrease in functional capacity. The general objecti

Mastitis is the most important production disease in dairy farming, leading to considerable inefficiency in production. In 1992, an important paper describing a simple but very useful economic framework for production diseases in animal farming was published. In a systemic literature search, 77 articles were found on the economics of mastitis. Throughout the years, little progress has been made to improve the economic framework regarding production diseases in animal farming, but methodological progress was made in the biological aspect of bioeconomic models. Research focused on the failure co

Abstract:Animals often select for habitats that increase their chance of survival by balancing the need to acquire food, reproduce and avoid predation. Perennial blooms of golden jellyfish (Mastigias papua etpisoni) are present in Jellyfish Lake, Palau, a popular tourist destination. Based on the species’ economic importance and unusual behavioural complexity, increased understanding of jellyfish habitat selection is necessary. We used a novel approach, a REMUS autonomous underwater vehicle, to quantify jellyfish distribution, abundance and habitat, and compared these findings to traditional m

Differences in banding scales for milk quality penalties, as determined by bulk tank somatic cell count (SCC), prevent the use of a single economic value for SCC in an overall economic-genetic selection index (Veerkamp et al., 1998) such as, Profitable Lifetime Index or £PLI. But SCC could be used as a predictor of mastitis as genetic correlation estimates between mastitis and SCC are medium to high (review of Mrode and Swanson, 1996). This suggests that, although deriving a direct single economic value (EV) for SCC based on bulk tank SCC is difficult, a single financial value could still be a

Abstract Increased incidence of protothecal mastitis has been recorded in several countries in the past ten years. The main goal of this article is to draw the attention of scientific and professional community to the emerging issue of mammary protothecosis. The article collates currently known facts about infection reservoirs, predisposing factors for the development of mastitis, clinical manifestations of the disease, and potential transmission routes within the herd as well as the measures for control and eradication. We would like to point out that identification of protothecal mastitis on

Current annual losses due to mastitis in Dutch dairy herds were calculated to av. Dfl 136/cow per yr, which equals approx. 12% of net return on labour and management per cow on a typical farm. Reduction in milk and fat yield accounts for 70% of these losses. Streptococcal infections were found to have the highest economic impact, causing almost 40% of total losses.

Mastitis remains one of the major disease in dairy herds, causing profound economic losses to the entire milk production chain due to changes in the milk quality and milk yield. A one year cross-sectional longitudinal survey was carried out to evaluate milk yield losses associated with occurrence of clinical mastitis cases in one dairy herd. Cows that had clinical mastitis and clinically healthy cows during lactation were included in the study. The traits analyzed were the average of the monthly test day milk yields, cow parities and days in lactation while first case of clinical mastitis was

Mastitis is an inflammation in the breast, which may involve a bacterial infection. Breast infection during breastfeeding is a common phenomenon that requires immediate and appropriate treatment. Without proper treatment, inflammation may lead to the cessation of breastfeeding. Another potential complication is the development of an abscess. Based on the nutritional and immunological value of breast milk, the recommendations of the American Academy of Pediatrics (AAP) and the World Health Organization (WHO) is exclusive breastfeeding up to 6 months of age, followed by continued breastfeeding a

Abstract. Mastitis is the most frequent and important disease in the dairy industry worldwide, which leads to great economic losses in the dairy industry (Nash et al. 2003). Direct selection for resistance to clinical mastitis may be very difficult and indirect selection has been practiced widely. The recommended measure is to record herd milk somatic cell scores (SCS) based on the positive correlation between clinical mastitis and milk SCS (Rupp et al. 1999).

SUMMARY Ovine mastitis causes varying economic fosses in all countries where sheep are kept. A survey of 3128 breeding ewes in 22 farms in two areas with different management practices in Southern Brazil showed that the average prevalence of subclinical and chronic mastitis was 14.1% of ewes with at least one affected gland. From those, 4.49% were also bacteriologically positive. The prevalence in individual farms varied from 0 to 37% of ewes with clinical abnormalities of the udder. The overall prevalence was greater in Area II, where meat breeds predominate and animals are housed at night. I
