A single-visit-multiple subject formal survey technique was used to collect data from 75 small-scale dairy farming households which were selected at random and were interviewed using a pre-tested, semi-structured questionnaire. Seventy-three (97.3%) dairy farming was practiced under an intensive management system. Among the selected dairy farms, only (33.3%) were kept in good hygienic condition. Artificial insemination was common (69.3%) breeding system practiced in most dairy farms of studying area. This study discovered that only a few dairy farms (2.7%) undergo periodic vaccination. It appeared from the study that morbidity loss of animals was primarily caused by mastitis which calculated (42.7%), black leg (32%), lumpy skin disease (21.3%), milk fever (17.3%), heart water (10.7%) and foot rote (5.3%) in order of their decreasing order. The results of this survey revealed that mastitis was ranked as the number one disease of dairy animals while foot rote was list reported disease in the study area. Morbidity loss of production and productivity was estimated to the financial loss of (812,600 birrs) per year. Not only morbidity loss, in some farms, mortality was also common problems of the study area. Mainly common diseases such as heart water (6.7%), milk fever (5.3%), back leg (2.7%), and lumpy skin disease (1.7%) were major causes of mortality in few farms. This in turn estimated the financial loss of (625,000 birrs). Eventually, overall annual financial loss as a result of mortality and morbidity was estimated to be (1,437,600 birrs). The outbreak of lumpy skin disease and blacklegs could be controlled through improving veterinary services with respect to adequate vaccination and heart water (seasonal tick infestation) would be alleviated by spraying. The aim of the study was to assess assessment on economic losses due to animal health and production constraints in Jimma town intensive dairy farms, Jimma, Ethiopia.

Economic losses due to bovine mastitis is estimated to be $2 billion in the United States alone. Antimicrobials are used extensively in dairy farms for prevention and treatment of mastitis and other diseases of dairy cattle. The use of antimicrobials for treatment and prevention of diseases of dairy cattle needs to be prudent to slow down the development, persistence, and spread of antimicrobial-resistant bacteria from dairy farms to humans, animals, and farm environments. Because of public health and food safety concerns regarding antimicrobial resistance and antimicrobial residues in meat and milk, alternative approaches for disease control are required. These include vaccines, improvements in housing, management practices that reduce the likelihood and effect of infectious diseases, management systems and feed formulation, studies to gain a better understanding of animal behavior, and the development of more probiotics and competitive exclusion products. Monitoring antimicrobial resistance patterns of bacterial isolates from cases of mastitis and dairy farm environments is important for treatment decisions and proper design of antimicrobial-resistance mitigation measures. It also helps to determine emergence, persistence, and potential risk of the spread of antimicrobial-resistant bacteria and resistome from these reservoirs in dairy farms to humans, animals, and farm environments.

Milk Fever Prevention

Despite being studied extensively, there are still many knowledge gaps in milk fever prevention and it is still a prevalent disease. Various interventions have been used in its prevention; however, none has proven to be entirely effective. The study aimed to assess the effectiveness of high dose vitamin D3 parenteral (intramuscularly) administration and the mechanism of its action by studying blood minerals and biochemical bone markers. Further, we assessed the potential of biochemical bone markers, measured in the close-up dry period, as predictors of clinical milk fever after calving. The study was conducted on 56 high yielding, clinically healthy dairy cows, before their 4th or higher lactation. They were divided into three groups based on season (summer and winter) and administration (vitamin D). The winter group was considered as the control group. Cows (n = 13) were parenterally administered a single dose of 10 million IU of vitamin D3 (DUPHAFRAL® D3) ranging between 10 and 2 days before calving (median = 3 days). Each cow was blood sampled once during four sampling period ranges: ~1 month before calving, 10 to 2 days before calving, 12–48 h after calving and 10–20 days after calving. The samples were analyzed for blood minerals, bone specific alkaline phosphatase (bALP) and C-terminal telopeptide of type I collagen (CTx), alkaline phosphatase, and estradiol. Values were compared between samplings and groups. A receiver operating characteristic (ROC) analysis and logistic regression were used to assess the diagnostic accuracy of biochemical bone markers in predicting milk fever. In this study high dose vitamin D3 supplementation did not statistically reduced the incidence of milk fever (milk fever incidences were 15.4, 39.1, and 25% in the vitamin D, winter and summer groups, respectively). A significant effect of vitamin D3 administration on blood minerals or biochemical bone markers was not found at any sampling. We found that the use of biochemical bone markers in the close-up dry period to predict clinical milk fever was applicable only in the winter (housed) group. The area under the curve (AUC) for bALP was 0.804 and 0.846 for CTx using ROC analysis. The bALP curve had the best ratio at the cut-off point 13.85 U/L with 90% sensitivity and 64.3% specificity. While CTx had the ratio of 90% sensitivity and 78.6% specificity at the cut-off point 0.149 ng/mL. Close-up dry dairy cows with CTx ≥0.121 ng/mL had a 3.8 times higher chance of succumbing to milk fever. We were unable to prove that high dose vitamin D3 parenteral administration is a viable technique for milk fever prevention. Biochemical bone markers are a promising tool for predicting milk fever; however, further studies are needed to confirm their clinical use.
