Relationship between system of raising Egyptian buffaloes and the effect of climate conditions on the helminthic infection rate, middle delta, Egypt

This study included 1278 buffalos from 160 herds belong to 32 villages in the Middle Delta of Egypt randomly chosen to study factors which can influence infection with gastrointestinal parasites. Relationship between number of parasites, herd size, resources of water and season of the year was investigated. The results showed that Fasciola gigantica infection recorded the highest percentage [48.04%], followed by Neoascaris vitulorum and Eimeria spp. Percentage rates of parasitic infection [single, double or triple] in each animal were 62.80%, 29.43% and 7.77%, respectively. Infection rate tended to increase with herd size in most of the cases. Resource of water had highly significant effect on infection rate. The highest infection was recorded in summer and the lowest in spring or winter. The study also showed a negative and highly significant correlation between infection and number of parasites [0.99]. Herd size did not associate with infection, while temperature and relative humidity correlated significantly with infection rate [0.67 and 0.78, respectively]

Effects of ration and fasciola infection on some blood parameters of ewes

This study was conducted using fourty cross-bred ewes in 5 groups of which one was kept as a control and the others were infected with metacercariae of Fasciola gigantica twice at the beginning of the experiment and 200 days from the first. The four infected groups fed on basal ration or high protein ration with or without mineral mixture. Blood samples were taken from the five groups to assess the concentrations of plasma fibrinogen and serum total proteins, albumin, glubulin, calcium and inorganic phosphorous. Results indicated that ewes total serum protein, albumin and globulin were decreased by Fasciola infection. The decrease was only significant in ewes fed basal ration with or without mineral mixture. Mineral mixture had no effect on the later blood parameters of infected ewes although little improvement in blood serum globulin was noticed .Plasma fibrinogen decreased significantly by infection. The level of plasma fibrinogen was improved by feeding high protein ration but did not affect by adding mineral mixture to any of the ration used. Infection was also found to decrease blood serum inorganic phosphorous but not calcium level .Feeding high protein ration with or without mineral supplement maintained blood serum inorganic phosphorous as that of the uninfected ewes. Blood serum calcium to phosphorous ratio of ewes fed Only basal ration was significantly higher than that of other groups
