Here, economic losses caused by cattle parasites in Mexico were estimated on an annual basis. The main factors taken into consideration for this assessment included the total number of animals at risk, potential detrimental effects of parasitism on milk production or weight gain, and records of condemnation on livestock byproducts. Estimates in US dollars (US$) were based on reported yield losses in untreated animals. These estimates reflect the major effects on cattle productivity of six parasites, or parasite group. The potential economic impact (US$ millions) was: gastrointestinal nematodes US$ 445.10; coccidia (Eimeria spp.) US$ 23.78; liver fluke (Fasciola hepatica) US$ 130.91; cattle tick (Rhipicephalus microplus) US$ 573.61; horn fly (Haematobia irritans) US$ 231.67; and stable fly (Stomoxys calcitrans) US$ 6.79. Overall, the yearly economic loss due to the six major parasites of cattle in Mexico was estimated to be US$ 1.41 billion. Considering that the national cattle herd registered in 2013 included 32.40 million head, the estimated yearly loss per head was US$ 43.57. The limitations of some of the baseline studies used to develop these estimates, particularly when extrapolated from local situations to a national scale, are acknowledged. However, the general picture obtained from the present effort demonstrates the magnitude and importance of cattle parasitism in Mexico and the challenges to maximize profitability by the livestock industry without adapting sustainable and integrated parasite control strategies.

The Impact

The profitability of livestock activities can be diminished significantly by the effects of parasites. Economic losses caused by cattle parasites in Brazil were estimated on an annual basis, considering the total number of animals at risk and the potential detrimental effects of parasitism on cattle productivity. Estimates in U.S. dollars (USD) were based on reported yield losses among untreated animals and reflected some of the effects of parasitic diseases. Relevant parasites that affect cattle productivity in Brazil, and their economic impact in USD billions include: gastrointestinal nematodes - $7.11; cattle tick (Rhipicephalus(Boophilus) microplus) - $3.24; horn fly (Haematobia irritans) - $2.56; cattle grub (Dermatobia hominis) - $0.38; New World screwworm fly (Cochliomyia hominivorax) - $0.34; and stable fly (Stomoxys calcitrans) - $0.34. The combined annual economic loss due to internal and external parasites of cattle in Brazil considered here was estimated to be at least USD 13.96 billion. These findings are discussed in the context of methodologies and research that are required in order to improve the accuracy of these economic impact assessments. This information needs to be taken into consideration when developing sustainable policies for mitigating the impact of parasitism on the profitability of Brazilian cattle producers.

ABSTRACT: Infection by Fasciola hepatica is an important cause of economic loss in cattle raised in Brazil and others countries. In slaughterhouses, the losses are mainly associated with condemnation of livers; however, it is believed that these losses can extend to diminished carcass yield and productivity throughout the life of the animals. Three slaughterhouses with a daily routine of approximately 15-20 cattle slaughters were monitored from July 2016 to November 2017. After sample collection, weighing, and liver assessment, statistical studies were conducted to determine disease prevalence and measurement of economic losses caused by fasciolosis through condemnation of the organ of choice of the parasite. Of the 210 livers assessed, 79 (37.6%) were condemned because of presence of F. hepatica, 87 (41.4%) were considered appropriate for human consumption, and 44 (20.9%) were considered inappropriate because of some other macroscopic lesions. The aim of this study was to estimate the prevalence of fasciolosis, correlate epidemiological and clinical-pathological aspects, and estimate the economic losses caused by the disease. It is estimated that the losses in southwestern Rio Grande do Sul state could reach R$ 36,943,532.60 (37.6%; 95% CI = 30,753,525.80 - 43,526,55.65) or US$ 11,437,626.20 (37.6%; 95% CI = 9,521,215.40 - 13,475,713.80) only because of condemnation of livers.

Beef Suckler

Endoparasites are one of the major health issues in beef suckler cows and can cause economic losses. As studies on the parasitological status of beef suckler cow herds are rare, the aim of this study was to evaluate the status quo of the parasite burden in herds at four representative locations in Germany. Additionally, the farmers’ pasture management and deworming strategies were documented. Based on these data, the second aim of the study was to develop recommendations for improved deworming and pasture hygiene management. A total of 708 faecal samples were examined with parasitological routine methods. Results revealed Fasciola hepatica, gastrointestinal nematodes (GIN), Eimeria species (spp.), Moniezia spp. and Dictyocaulus viviparus as the most frequent findings. Clinical signs of parasitic diseases were not found during the farm visits. Statistical analyses showed a significant effect of the age status of the animal on the parasitological status in general. Due to the percentage of occurrence, detailed statistical analysis was performed for Eimeria, GIN and Fasciola hepatica, confirming the effect of age status. Assessing the parasitological status of beef suckler cows as routine procedure could help to establish an improved parasite-control management on a farm-individual basis.

Abstract Background Pasture management influences the prevalence and impact of the pasture parasites (PP) in cattle herds, which cause production-limiting disease worldwide. Evaluating farmer management strategies is vital when considering sustainable PP control practices. The aim of this questionnaire-based study was to describe the pasture management and control strategies regarding PP in Norwegian beef cattle (BC) and dairy cattle (DC) production systems with a focus on gastrointestinal nematodes (GIN) and Fasciola hepatica. Results A total of 745 responses from BC (return rate 20.5%) and 1347 responses from DC farmers (30.7%) were included. The mean total pasture time for DC was 4.2 months for first-season grazers and 4.3 months for second-season grazers and cows, while the corresponding finding in BC was 5.4 months. Home pasture was used for most of the pasture period, particularly for first-season grazer dairy heifers (81%), which were also commonly grazed on the same pasture every year (79%). For most farmers it was necessary for grazing areas to be used for cattle for more than one season (77% of BC farmers and 89% of DC farmers). However, changing the pasture during the season was common in both DC (67%) and BC (70%) herds. The majority of DC farmers (60%) stated that they did not consider that they had a problem with PP. Of the remaining 40%, few respondents could specify whether their herds had a problem due to infection by GIN (11%) or liver flukes (12%). Treatment for GIN was performed by 52% of DC and 34% of BC farmers. Diagnostic faecal samples were collected upon suspicion of parasitic disease by 5% of DC and 16% of BC farmers. Veterinarians were stated as a central source of information about parasite management and treatment. Conclusions Potential risks for exposure to PP were identified, such as use of the same pasture every year for first-season grazers and frequent use of home pasture. The perception of problems related to PP appeared low. Regular anthelmintic treatment without concurrent use of diagnostic faecal samples seems to be common practice.

Pioneer Effort

Honeybees are of great importance because of their role in pollination as well as for hive products. The population of managed colonies fluctuates over time, and recent monitoring reports show different levels of colony losses in many regions and countries. The cause of this kind of loss is a combination of various factors, such as the parasitic mite Varroa destructor, viruses, pesticides, management practices, climate change, and other stress factors. Having in mind that the economic aspect of honeybee colony losses has not been estimated, a pioneer effort was made for developing a methodology that estimates the economic impact of honeybee colony losses. Winter loss data was based on 2993 answers of the COLOSS standard questionnaire survey of honeybee winter colony losses for 2016/2017. In addition, market and financial data were used for each country. In a comparative analysis, an assessment on the economic impact of colony losses in Austria, Czechia, and Macedonia was made. The estimation considered the value of the colonies and the potential production losses of the lost colonies and of surviving but weak colonies. The direct economic impact of winter honeybee colony losses in 2016/2017 in Austria was estimated to be about 32 Mio €; in Czechia, 21 Mio €; and in Macedonia, 3 Mio €. Economic impact reflects the different value levels in the three countries, national colony populations, and the magnitude of colony losses. This study also suggests that economic losses are much higher than the subsidies, which underlines the economic importance of honeybees for the agricultural sector.

Kejadian tumpahan minyak di laut bisa terjadi sewaktu-waktu dan dimana saja khususnya yang memiliki kedekatan dengan jalur perkapalan dan aktivitas pengeboran minyak. Hal ini menuntut kewaspadaan pemerintah sekaligus kemampuan untuk menanggulangi kejadian yang terjadi secara cepat. Seiring dengan itu, pemerintah juga harus segera dapat menghitung nilai kerugian atau dampak ekonomi yang ditimbulkan. Penelitian ini bertujuan untuk menyusun pedoman perhitungan dampak kerugian akibat tumpahan minyak dengan pendekatan valuasi ekonomi. Penilaian dengan pendekatan ini memberi keuntungan yaitu terhitungnya seluruh manfaat barang dan jasa yang hilang baik yang bersifat ekonomi langsung, ekologi maupun sosial budaya. Secara total nilai dampak ekonomi dihitung dengan memasukkan tiga komponen yaitu biaya kerugian ekonomi yang dikompensasi, biaya rehabilitasi dan biaya administrasi penghitungan kerugian.Tittle: Economic Valuation Approach for Calculating the Economic Impact Due to Oil Spill on Coastal and MarineOil spills in the sea water can occur at anytime and anywhere especially on sites are closely associated with shipping and oil drilling activities. This issue requires government vigilance and ability in order to cope with it responsively. The government must also be able to calculate the economic loss. The purpose of this research is to compose a guidance of economic valuation for oil spill economic impact. The use of economic valuation give advantages where the loss of all benefits of goods and services, that include economic, ecological and socio-cultural value, are comprehensively counted. In total, the economic impact is calculated based on three components: the cost of compensated economic losses, rehabilitation costs and administrative costs of calculating losses.

AbstractThis research measures the epidemiological and economic impact of COVID-19 spread in the US under different mitigation scenarios, comprising of non-pharmaceutical interventions. A detailed disease model of COVID-19 is combined with a model of the US economy to estimate the direct impact of labor supply shock to each sector arising from morbidity, mortality, and lockdown, as well as the indirect impact caused by the interdependencies between sectors. During a lockdown, estimates of jobs that are workable from home in each sector are used to modify the shock to labor supply. Results show trade-offs between economic losses, and lives saved and infections averted are non-linear in compliance to social distancing and the duration of the lockdown. Sectors that are worst hit are not the labor-intensive sectors such as the Agriculture sector and the Construction sector, but the ones with high valued jobs such as the Professional Services, even after the teleworkability of jobs is accounted for. Additionally, the findings show that a low compliance to interventions can be overcome by a longer shutdown period and vice versa to arrive at similar epidemiological impact but their net effect on economic loss depends on the interplay between the marginal gains from averting infections and deaths, versus the marginal loss from having healthy workers stay at home during the shutdown.

Internal Parasites

The changes in the cattle farming system in Poland observed in the last two decades and related to its evolution into massive scale, specialized farming may have an influence on the occurrence of parasitoses. The study was aimed at showing differences in the prevalence of internal parasites in cattle depending on the herd size, management system and production type. In the period of October to December in 2016 and 2017, the study covered 46 farms with a livestock density from 2 to 160 animals (over 1 year of age), including 25 farms with a confined management system, 12 farms using pastures occasionally and 7 farms with animals using pastures during the whole season. Out of these farms, 36 were oriented towards dairy cattle and 10 to beef cattle. The analytical methods involved flotation, sedimentation and the Baermann technique. In total, 276 feces samples were analyzed. The analysis involved a representative number of samples from each farm, depending on the herd size: from 100% of the animals in the smallest farms to 10% in the largest ones. In total, eleven different taxa of parasites were identified, and their general prevalence was as follows: Eimeria spp. 24.6%, Buxtonella sulcata 25.7%, Strongyloides papillosus 7.6%, gastrointestinal nematodes (Trichostrongylidae, Chabertia, Oesophagostomum) 35.1%, Nematodirus spp. 4.7%, Bunostomum phlebotomum 7.6%, Trichuris spp. 6.2%, Fasciola hepatica 6.9%, Paramphistomum spp 2.5%, Moniezia spp. 2.9%, Dictyocaulus viviparus 2.5%. The forms of parasites were found in samples coming from all studied herds. Invasions of protozoa (Eimeria, Buxtonella) were most commonly found in dairy cattle, in large herds managed in a free stall barn system and in beef cattle, in large herds managed in a pasture system. These herds were also most frequently infected with gastrointestinal nematodes. The invasions of trematodes, tapeworms and pulmonary nematodes were detected only in cattle using pastures, most commonly in large herds..

ABSTRACT: Rabies is among the most common neurological disease in cattle in Brazil, causing significant economic losses. Data on the economic impact of rabies in livestock are available in several countries. However, in Brazil, these data focus mainly on the public health point o view, emphasizing the costs related to the prevention of rabies in humans, in dogs, or wildlife. Specific studies carried out in different regions of Brazil indicate critical economic losses caused by rabies in cattle in this country. However, the studies on the losses caused by the disease in cattle lack a detailed analysis of the affected rural properties based on data from official disease control agencies. The objective of this work was to evaluate the economic impact of bovine rabies, and its mitigation through antirabies vaccination in rural properties in Mato Grosso do Sul, Midwestern Brazil.

Trim Loss

Abstract Non-edible trim loss has been shown to reduce value in market hogs (Johnson et al., 2013). Non-edible trim loss from pork carcasses results from; adhesions, arthritis, and abscess (Keenlislide, 2005). Sow harvest facilities often encounter sow carcasses having one or more non-edible trim loss factors (Knauer, 2007). Non-edible trim loss observed repeatedly in high levels will result in carcass discounts to the seller. The objective of this study was to evaluate the economic impact of non-edible trim loss from cull sow carcasses. Data were collected as a convenience sample from a Midwestern cull-sow harvest facility. This facility focuses on harvesting high quality animals and harvesting “lean” or “boner” sows occurs relatively infrequently. For this study, trim was expressed as a percentage of carcass weight. At this harvest facility all carcasses have some non-edible trim loss. The average total pre-trim carcass weight was 149 kgs (n = 87). The relative percentage of non-edible trim loss was sorted into quartiles. Based on percent trim and average carcass weight the quartiles were classified as 1st Qu. = normal trim (0.5% – 1.2%, n = 22), 2nd Qu. = low trim (1.2% – 2.1%, n =20), 3rd Qu. = medium trim (2.1% – 3.4%, n = 21), and 4th Qu. = high trim (3.4% – 20.9%, n = 22). A 5-year average cull sow price (USDA, ERS) was utilized to calculate the economic loss represented from each quartile of percentage trim. Normal trim, low trim and medium trim showed to have low economic impact. High trim loss had an average economic loss of $9.37 (s.d. = 6.9) on a standardized basis. Substantial economic losses are observed when high trim is measured. Additional work is needed in identifying significant trim loss prior to harvest.
