ABSTRACT: Gingivitis is an infectious inflammatory process that generates local and systemic conditions, compromising the masticatory capacity of animals. Virginiamycin controls prevents gingivitis necrotizing in cattle. However, interaction effect with different sera salivary elements remain unknown. The present 6-month longitudinal study evaluated hematological, metabolic, buffering profiles ...

Groups of 120 male and 120 female rats were exposed by inhalation to 0, 2, 6, or 15 ppm formaldehyde vapor 6 hr/day, 5 days/week, for 18 months of a 24-month study. The present communication describes interim findings based on data available after 18 months of exposure. Squamous cell carcinomas occurred in the nasal cavities of 36 rats exposed to 15 ppm formaldehyde. The tumors ranged from smal...

The antimicrobial susceptibility of 201 Listeria monocytogenes isolates from foods, environments, animals and human patients in Japan was determined. All isolates were susceptible to ampicillin, the first choice of drug for listeriosis treatment, chloramphenicol, dihydrostreptomycin, erythromycin, enrofloxacin, gentamicin, kanamycin, lincomycin, nosiheptide, salinomycin, vancomycin, and virgini...

A semi-field study was carried out to evaluate the effect of two medicinal herbs, individually and in combination, on growth performance, carcass traits, nutrient digestibility and immune response of broiler chickens.  A total of 384 one-day-old straight-run Arbor Acres broiler chickens were allocated into 24 floor pens prepared in a commercial broiler house. Pen-groups were fed one of the foll...

Three experiments were conducted to evaluate the effect of feeding pharmacological concentrations of zinc (Zn), from organic and inorganic sources, on growth performance, plasma and tissue Zn accumulation, and Zn excretion of nursery pigs. Blood from all pigs was collected for plasma Zn determination on d 14 in Exp. 1, d 7 and 28 in Exp. 2, and d 15 in Exp. 3. In Exp. 1, 2, and 3, 90, 100, and ...

This study was conducted to determine the influence of fulvic acid (FA) and probiotic (PB) supplementation on performance, nutrient digestibility, blood parameters and immunity of pigs. The trial 1 evaluated the effect of FA and probiotic on nutrient digestibility of pigs at approximately 20 kg. The trial 2 examined the effect on performance, blood parameters and immune response of 80 weanling ...

After both intravenous injection and oral administration, the factor Js/L1 of virginiamycin was rapidly diluted or absorbed. It then disappeared from the plasma stream at a first order exponential rate with a half life of approximately 5hours following a process of both tissue fixation and body excretion. The bile was the main route by which the antibiotic was excreted from the body. The ratio ...

This study investigated the levels of the antibiotic tetracycline contained in cow milk, goat milk, butterfat, soft cheese and yoghurt samples. High performance liquid chromatography (HPLC) standard methods were used for the detection and quantification of tetracycline in 40 dairy products samples. All the analysed samples contained residues of tetracycline antibiotics. The mean tetracycline re...

To characterize the effects of several subtherapeutic antibiotic combinations on the abundance and diversity of fecal microbes, 400 weaned pigs were selected and randomly assigned to 8 groups, where they were continuously fed different antibiotic combinations for 28 days. Then, a total of 48 pigs were randomly selected to collect feces samples for DNA extraction and 16S rRNA high-throughput seq...
