Biochemical effect of some feed additives and immunological response in broilder chickens

This study was investigated the effects of dietary supplementation with prebiotics beta-glucan, MOS 500 and Bio MOS [registered sign] on the broilers performance, biochemical parameters and immune response for 5 weeks. One hundred and twenty 1-day-old broiler chickens were randomly assigned to 4 dietary treatment groups as follows: control, beta-glucan [1g/kg], MOS 500 [0.5g/kg] and Bio MOS [registered sign] [1g/kg]. Each treatment was divided into three replicates [ten birds/ replicate]. The overall BW gains of birds treated with prebiotics were significantly [P <0.01] higher than those of the control group. During the experiment, the birds fed supplemental Bio MOS [registered sign] gave the best FCR followed by beta-glucan MOS 500 and then the control group. Addition of these prebiotics were improved the levels of serum total protein and globulin which in turn support the immune function against NDV and IBDV. In addition to, supplementation of broiler chicks by beta-glucan, MOS 500 and Bio-MOS [registered sign] had no effect on the liver transmination enzymes and some kidney function which represent the non pathological metabolism of the liver and kidneys indicating their safety supplementation in broiler feed

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
