Detecção de Salmonella Enteritidis em ovos de codornas japonesas submetidas a dietas com diferentes níveis de cálcio e fósforo

The eggs are pointed in several studies as the main cause of human salmonellosis. Have been identified that eggs are eaten raw or poorly processed are mainly responsible for outbreaks of human infection with Salmonella spp. Besides causing problems to public health, the presence of bacteria impedes or hinders the international food trade, as a sanitary barrier. Several factors predisposing to contamination of the internal contents of eggs for Salmonella spp., including the egg shell quality (shell quality), which is related to levels of calcium (Ca) and phosphorus (P) in the diet of quails . The experiment used eggs of Japanese quail under different diets containing two levels of Ca (2.0 and 3.5%) and two levels of available P (0.25 and 0.45%). Eggs of 120 japanese quails were divided into four treatments with three replicates. The experiment was divided into three production stages: initial, intermediate and final. Were assessed at each stage the presence of bacteria in internal and external content of experimentally contaminated eggs during periods of 0, 24, 96 and 168 hours after immersion in broth containing Salmonella Enteriditis. Salmonella Enteriditis was detected in the shell during all periods of storage, in decreasing amounts in all treatments. None of the treatments within the three production stages analyzed, we detected significant amounts of the bacteria inside the egg, in our experimental conditions. Therefore, the levels of Ca and P in the diets of quail do not determine higher or lower risks to public health represented by eggs

Poultry offal meal traceability in meat quail tissues using the technique of stable carbon (13C/12C) and nitrogen (15N/14N) isotopes

Studies on the detection of animal by-products in poultry meat are rare, and non-existent on quail meat. This study aimed at detectiong increasing levels of poultry offal meal (POM) in quail meat, using carbon (13C/12C) and nitrogen (15N/14N) stable isotopes technique. Sixty four on-day-old male quails derived from a commercial farm were randomly distributed into seven different groups, which were fed experimental diets containing 0, 1.5, 3.0, 4.5, 6.0, 7.5, and 15% of POM. Diets were formulated to contain equal energy, protein, and amino acid levels. Four individuals per treatment were sacrificed at 42 days of age for breast muscle (Pectoralis major), keel, and tibia collection, which were subsequently submitted to analyses. Isotopic δ13C and δ15N enrichment was observed in all analyzed tissues, with the lowest detection level of 3% dietary inclusion of poultry offal meal.

The genetic link between the Chinese bamboo partridge (Bambusicola thoracica) and the chicken and junglefowls of the genus Gallus.

Further comparison of mitochondrial control-region DNA base sequences of 16 avian species belonging to the subfamily Phasianinae revealed the following: (i) Generalized perdicine birds (quails and partridges) are of ancient lineages. Even the closest pair, the common quail (Coturnix coturnix japonica) and the Chinese bamboo partridge (Bambusicola thoracica), maintained only 85.71% identity. (ii) The 12 species of phasianine birds previously and presently studied belonged to three distinct branches. The first branch was made exclusively of members of the genus Gallus, while the second branch was made of pheasants of the genera Phasianus, Chrysolophus, and Syrmaticus. Gallopheasants of the genus Lophura were distant cousins to these pheasants. The great argus (Argusianus argus) and peafowls of the genus Pavo constituted the third branch. The position of peacock-pheasants of the genus Polyplectron in the third branch was similar to that of the genus Lophura in the second branch. Members of the fourth phasianine branch, such as tragopans and monals, were not included in the present study. (iii) The one perdicine species, Bambusicola thoracica, was more closely related to phasianine genera Gallus and Pavo than to members of other perdicine genera. The above might indicate that Bambusicola belong to one-stem perdicine lineage that later splits into two sublineages that yielded phasianine birds, one evolving to Gallus, and the other differentiating toward Pavo and its allies.
