BACKGROUND Tylosin and Josamycin are macrolide antibiotics. They are used in the treatment of pneumonia, arthritis and mastitis in cattle, and mycoplasma infections in poultry. The incorrect use of antibiotics has lead to the presence of antibiotic residues in foods. The residues cause toxic effects on consumers. RESULTS A simple and sensitive method was optimized and validated for the analys...

This study was conducted to evaluate the efficacy of sodium hypochlorite (NaOCl, 0-200 mg/kg), thiamine dilauryl sulfate (TDS, 1,000 mg/kg), and ultrasound (37 kHz, 380 W) on reducing Salmonella Typhimurim, mesophilic aerobic bacteria (MAB), and coliforms on chicken skin. Chemical and physical treatments were applied for 5 min either singly or jointly, and Salmonella previously inoculated on ch...

The aim of this study was to explore the isolation and culture process of Beijing fatty chicken primordial germ cells (PGCs) and investigate their biological characteristics. The PGCs isolated from the genital ridges of Beijing fatty chicken (Gallus domesticus) embryos after 5.5 days of incubation were co-cultured with mice embryonic fibroblasts (MEF). The results showed that the PGCs of the Be...

BACKGROUND Osteoprotegerin (OPG) has been reported to prevent bone resorption by inhibiting the formation, function, and survival of osteoclasts in a variety of animal models. However, the effects of OPG on bone metabolism in avian species have not been described. The objective of this study was to investigate the effects of chicken OPG (chOPG) expressed in chicken embryo fibroblasts (CEFs) on ...

The Tokay gecko (Gekko gekko), a nocturnal lizard, has two kinds of visual pigments, P467 and P521. In spite of the pure-rod morphology of the photoreceptor cells, the biochemical properties of P521 and P467 resemble those of iodopsin (the chicken red-sensitive cone visual pigment) and rhodopsin, respectively. We have found that the amino acid sequence of P521 deduced from the cDNA was very sim...

Two artificial diets developed for rearing Lygus spp., a fresh yolk chicken egg based-diet (FYD) and a dry yolk chicken egg based-diet (DYD), were evaluated as an alternative food source for rearing the southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae). Survival to adult was 97.3 and 74.67%, respectively, on the fresh and dry yolk diets. Insects fed FYD had 100% surviva...

A rehydratable dry-film plating method for Staphylococcus aureus in foods, the 3M Petrifilm Rapid S. aureus Count Plate method, was compared with AOAC Official Method 975.55 (Staphylococcus aureus in Foods). Nine foods-instant nonfat dried milk, dry seasoned vegetable coating, frozen hash browns, frozen cooked chicken patty, frozen ground raw pork, shredded cheddar cheese, fresh green beans, pa...

The need for chicken eggs is inseparable from the supply chain network. Green aspects in fulfilling networks have an impact on environment such as market cleanliness and egg quality. current condition of Kemang Market management has not led to environmental aspects. purpose this study identify priority criteria that can be applied green activities Market, Bogor Regency. method used Fuzzy Analyt...

this study was conducted at beresa watershed district of guraghe administrative zone, the southern regional state of ethiopia to evaluate the on-farm reproductive and egg production performances of local kei and its f1 crosses with fayoumi and rhode island red (rir) chicken breeds under farmers’ management. the local kei paternal line was mated with maternal lines of fayoumi and rir chickens to...

1. The absorption of zinc in humans from composite meals, was determined by extrinsic labelling of the meals with 65Zn and measurement of the whole-body retention of the radioisotope. 2. Low-Zn (mean 25 mumol) chicken meals with 150 g white bread or 225 g potatoes, carrots, turnips, cabbage or green peas were studied. The effect of a beet-pulp-fibre preparation used as a breakfast cereal, in br...
