Background This study evaluated the use of dietary vitamin E and polyphenols on growth, immune and oxidative status of weaned pigs fed peroxidized lipids. A total of 192 piglets (21 days of age and body weight of 6.62 +/- 1.04 kg) were assigned within sex and weight blocks to a 2 x 3 factorial arrangement using 48 pens with 4 pigs per pen. Dietary treatments consisted of lipid peroxidation (6% edible soybean oil or 6% peroxidized soybean oil), and antioxidant supplementation (control diet containing 33 IU/kg DL-alpha-tocopheryl-acetate; control with 200 IU/kg additional dl-alpha-tocopheryl-acetate; or control with 400 mg/kg polyphenols). Pigs were fed in 2 phases for 14 and 21 days, respectively. Results Peroxidation of oil for 12 days at 80 degrees C with exposure to 50 L/min of air substantially increased peroxide values, anisidine value, hexanal, and 2,4-decadienal concentrations. Fee...

222Rn is formed by the decay of 226Ra , then decays into 218Po and 214Po . Po ions electrostatically produced can be collected using a camera with a polarized high voltage then decays 218Po 214Pb particles emitting at 6.003 keV and thereafter decays 214Po 210Pb emitting particles at 7.687 keV. By measuring the concentration of these alpha particles in the camera can determine the concentration of radon in the air in an indirect way . The prototype has been developed using a measuring chamber 2 L stainless steel of a S3204 -09 PIN diode ( Hamamatsu ) bare body as alpha-particle detector . The camera and diode are polarized with a source of high voltage ( +500 V ) to collect ions and detect Po alpha particles that are then produced in the decay chain . Operations and digital functions are implemented on a PIC18F4550 microcontroller and the device has an internal USB module communication fo...

The aim of this study was to evaluate the effect of protein supplementation at service and before delivery on the load of gastrointestinal nematodes in naturally infested dairy goats. Two groups of 17 goats were evaluated: control group (SinSu) without supplementation and supplemented (ConSu) with 19% protein during service and 45 days prepartum. The animals were monitored every 15 days during service and in the 45 days before lambing and monthly during the rest of the trial. The parasitic load (eggs per gram of feces – epg) and their differentiation into genus were determined, in addition to the hematocrit, total proteins, body condition (BCS) and clinical and Famacha grade. The weight of the offspring and milk production at 90 days were recorded. No significant differences were found in epg of the two groups before lambing, but protein supplementation resulted in a lower parasitic lo...
