“…The cattle population in India is estimated to be 16.5% of the World cattle population (Ghosh et al ., 2006). In Kenya, immunization of cattle against ECF increased the weight gain by 5–10% and the milk yield by 25% (Nyangito et al ., 1995). From acute and subclinical theileriosis caused by T. orientalis, reduction in milk yield was 288 ± 90.4 and 153 ± 95.9 L cattle −1 per 100 days from a herd of 662 dairy cattle in Australia, respectively (Perera et al ., 2014).…”

“…But its rate due to ECF for calves and mature cattle was 15 and 10% in a farm of Uasin Gishu District of Kenya. After controlling ticks, mortality decreased from 80 to 2–4% in cattle (Nyangito et al ., 1995). While, its rate due to gastrointestinal nematodes in twice treated and non-treated animals were 19 and 14% respectively from 1046 N'Dama cattle during 1989–1994 in Gambia (Zinsstag et al ., 1997 b ).…”

“…The control cost/head in pastoral and ranch herds were US$ 4.90 ± 0.61 and 6.13 ± 0.85, respectively (Ocaido et al ., 2009). While in Kenya, cost of ECF control was US$ 51 and 50 cattle −1 annum −1 for small and large dairy farms from variable cost of US$ 38.64 and 1561, respectively for production (Nyangito et al ., 1995).…”

A systematic review on modelling approaches for economic losses studies caused by parasites and their associated diseases in cattle

Parasites reside inside or outside their hosts and get host nutrition and blood. Here, we have emphasized economic losses in cattle caused by parasitic diseases due to ecto- and endo- parasites (flies, ticks, mites and helminths). We have outlined different methods/models including economic evaluation techniques and dynamic analysis as a major class, used for the calculation of economic losses caused by parasites in cattle. According to already conducted studies, a decrease in production is mentioned in quantity and percentage while financial losses are expressed in the form of account with respect to per head, herd or for the specific study area. The parasites cause the reduced production and financial losses due to control, treatment and mortality costs. We calculated the average decrease in milk production and organ condemnation as 1.16 L animal-1 day-1 and 12.95%, respectively, from overall cattle parasitic infections. Moreover, the average calculated financial and percentage losses were US$ 50.67 animal-1 year-1 and 17.94%, respectively. Economically important parasitic diseases mentioned here are caused by specific spp. of protozoans and helminths according to data collected from the literature. Protozoan diseases include tick-borne diseases, coccidiosis, neosporosis, trypanosomiasis and cryptosporidiosis. Losses due to tick-borne infections were encountered for decreased milk production, mortality, treatment and control. Losses from coccidiosis were due to decreased weight gain, treatment costs and mortality. While abortion losses were encountered in neosporosis. Trypanosomiasis caused losses due to a decrease in milk yield. Moreover, only diagnostic (conventional or molecular techniques) cost was taken into account for cryptosporidiosis. Economically important nematode parasites are Oesophagostomum spp., Cooperia spp., Trichostrongylus spp., Strongyloides spp., Ostertagia spp. and Haemonchus placei. Due to the zoonotic importance of echinococcosis, Echinococcus granulosus is the most economically important cestode parasite. Losses caused by echinococcosis were due to organ condemnation, carcass weight loss and decreases hide value, milk production and fecundity. While, fascioliasis is one of the most economically important trematodal disease, which causes cirrhosis of the liver due to parasite migration, and thus, the organ becomes inedible. So, it would be helpful for farmers and researchers to approach these methods/models for calculation of parasitic losses and should adopt suitable measures to avoid long-term economic losses.

“…FARMSIM is an extension of the Farm Level and Income Policy Simulation (FLIPSIM) model available in Microsoft Excel format which has been used extensively to simulate the impacts of alternative policies and farming systems on representative farms (e.g. Nyangito et al, 1995, Nyangito et al, 1996a, Nyangito et al, 1996b, Richardson and Clair, 1981, Richardson et al, 1983, Richardson et al, 2000). FARMSIM is explicitly programmed to simulate small holder farms in developing countries.…”

HighlightsWe propose a modeling framework that assesses environmental and economical consequences of agricultural intensification.Agricultural interventions were evaluated using IDSS in two study sites in the Amhara region of Ethiopia.IDSS analyses indicate that a significant improvement in family incomes and nutrition can be achieved through the adoption of farming technologies such as irrigation technologies and nutrient management.
