Magnesium in the water of Japanese quails kept under comfort zone and under thermal stress

The objective was to evaluate the increasing levels of magnesium in the water supplied to laying quails (Coturnix coturnix japonica), kept in climatic chambers under thermoneutral temperature and thermal stress, on their performance and morphometry of their organs. The birds were distributed in a completely randomized design, 2x4 factorial arrangement, 2 temperatures (24 and 32 ºC) and 4 levels of magnesium in the water (50, 150, 250 and 350 mg L-1), with six replicates and eight birds per experimental unit. The data were subjected to analysis of variance and the means compared by the Tukey test at 5% probability level. The magnesium levels in the water did not affect (P > 0.05) the production performance and morphometry of the organs, with less water consumption at the magnesium level of 150 mg L-1, and birds kept at 32 °C had a reduction in feed consumption and feed conversion, but without affecting organ morphometry. Japanese quails in the production phase can consume water with magnesium levels up to 350 mg L-1 without having their production performance and morphometry of organs affected and raised in an environment with temperatures of up to 32 °C.

Hyperlipidemia Diet Reduces Superoxide Dismutase Inhibition Rate in the Brain Organ of Rattus norvegicus

Quail (Coturnix coturnix japonica L.) egg yolk is one of the high-fat foods which can trigger hyperlipidemia. The condition of hyperlipidemia can have an oxidative stress effect on the brain. Superoxide dismutase (SOD) is a natural antioxidant that acts as a defense mechanism against oxidative stress. The inhibition rate of SOD decreases when oxidative stress occurs. This study aims to determine the effect of quail egg yolk on the SOD inhibition rate of brain organs on a rat. This study used male Wistar rats aged 2-3 months with 200-300 grams of weight. The rats were divided into two groups. Each group was fed with ad libitum for two weeks. The A groups as control continued ad libitum consumption, and the B group was given additional quail egg yolk 5 ml / 200 g BW for 2 weeks. At the end of the study, the rats were terminated. The brain organs were examined for SOD inhibition rate with spectrophotometry. The mean SOD inhibition rate in the A and B groups was 74.14% ± 6.16 and 24.14% ± 5.65, respectively. The independent t-test showed significant differences in SOD inhibition rate between groups (p 0.001). Furthermore, quail egg yolk significantly reduced the SOD inhibition rate in the brain organ of the rat.

Medidas morfométricas del huevo fértil de codorniz (Coturnix coturnix japonica) sobre el peso al nacimiento

El estudio tuvo como objetivo relacionar medidas morfométricas del huevo de codorniz Coturnix coturnix japonica con el peso al nacimiento en una línea comercial de postura. Se evaluaron 274 aves al nacimiento, cuyos huevos fértiles fueron clasificados en tres categorías según el peso: (1) 10.00-10.99, (2) 11.00-11.99, (3) 12.00-12.99 g para la variable peso al nacimiento, mientras que las variables: diámetro transversal y diámetro longitudinal del huevo, índice de forma fueron evaluadas según cuartiles. Además se evaluó el sexo del ave. Se utilizó un modelo de bloques completamente al azar y correlaciones entre las variables cuantitativas. Se obtuvo una correlación media de 0.65 entre peso del huevo y diámetro longitudinal, y correlaciones bajas entre las variables diámetro longitudinal y transversal (0.15). El peso al nacimiento fue de 7.36±0.038, 7.92±0.036 y 8.47±0.058 g en las categorías 1, 2 y 3, respectivamente y de 7.83±0.0672, 7.81±0.0681, 7.69±0.0665 y 7.85±0.0682 g en los cuartiles 1, 2, 3 y 4, respectivamente. El índice de forma del huevo fue 70.22±0.321%. El peso de las codornices macho fue 7.84±0.0347 y en hembras de 8.00±0.0358 (p<0.05). El diámetro transversal y longitudinal del huevo permite seleccionar visualmente un huevo incubable, siendo el diámetro transversal el más preciso, debido a que no se quieren codornices pesadas al nacimiento.

Molecular Detection of Human Pathogenic Gastric Helicobacter Species in Wild Rabbits (Oryctolagus cuniculus) and Wild Quails (Coturnix coturnix)

Wildlife plays a major role in the maintenance and transmission of multihost pathogens. Several Helicobacter spp. have been described to have zoonotic potential; thus, human, domestic and wild animal interactions deserve more attention. In this study, the presence of the DNA of human pathogenic gastric Helicobacter species was determined in gastric samples collected from wild rabbits and wild quails during the national hunting campaigns in Portugal. Eleven out of the 12 wild rabbits (91.7%) and all six wild quails tested (100%) were PCR positive for one or more gastric Helicobacter species. In both animal species, H. felis, H. bizzozeronii and H. salomonis DNA were detected. In addition to these non-Helicobacter pylori Helicobacter spp. (NHPH), H. pylori DNA was also identified in gizzard samples of wild quails. These findings might indicate that wild rabbits and wild quails may act as reservoirs and contribute to the H. pylori and NHPH environment dissemination, causing both Public Health and One health concerns to arise.

Beyaz ve Kahverengi Varyetelerine Göre Japon Bıldırcın’larının (Coturnix coturnix japonica) Canlı Ağırlık ve Zoometrik Yapılarının Belirlenmesi

This study was carried out to determine some zoometric measurements and body weights in two different varieties of Japanese Quail (Coturnix coturnix japonica), white and brown. For this purpose, live weights and variables of twelve different body measurements were evaluated in 30 white and brown varieties (15 males, 15 females), a total of 60 six-week-old quails housed under the same nutritional and environmental conditions. Although higher values were obtained in terms of average body weights at six weeks of age compared to many of the literature reports, there was no difference in terms of the two-color varieties compared in this study, while females were found to be significantly heavier than males. While white quails had higher values than brown ones in terms of head width, beak width, beak length, sternum length, tarsus length and wing length, females had higher values in live weight, body length, chest circumference and tarsus diameter variables according to gender. Positive correlations were found between body weights of six-week-old Japanese quails and the variables of skull length, body length, sternum length, middle finger length, wing length, chest circumference and tarsus diameter. Considering the fact that the consumption of quail will increase for the spread of quail breeding, it can be recommended to carry out more comprehensive studies on the factors that will enable people to prefer quail in nutrition.

Fitoterapia en la producción de la codorniz (coturnix coturnix japónica)

El objetivo de la presente investigación fue evaluar el efecto de una tintura de ajo (Allium sativum) más orégano (Origanum vulgare) en la terapéutica de la coccidiosis y su repercusión en los parámetros productivos de la codorniz. Con cuatro tratamientos: T1 (libre de coccidiostático), T2 (Sulfaquinoxalina Sódica 34 mg + Vitamina K a razón de 10 mL por cada 3.5 litros de agua), T3 (balanceado libre de coccidiostático + 10% de tintura distribuidos en 10 mL tintura/1litro de agua), T4 (balanceado libre de coccidistático + 20% de tintura distribuidos en 20 mL de tintura/1litro de agua). La tintura se elaboró a partir de una solución madre de ambos aditivos por el método de maceración. Se empleó un diseño completamente al azar con seis repeticiones; cada unidad experimental conformada por cinco aves. Para establecer las diferencias entre medias de los tratamientos se empleó la prueba de Tukey (P≤0.05). Se evaluaron las variables: ganancia de peso, consumo de alimento, índice de conversión alimenticia, masa del huevo, porciento de postura. Los resultados indicaron que el tratamiento más favorable fue el balanceado libre de coccidiostático + 20% de tintura (Ajo y orégano) distribuidos en 20 mL de tintura/L de agua (T4). La coprología se analizó con la prueba cuantitativa de flotación en tubo de ensayo para el diagnóstico parasitológico veterinario; al inicio y final de la investigación; se registró una disminución significativa del número de ooquistes de coccidias por gramos de heces en los tratamientos T3, T4 al final de experimento.
