The objective of this work was to evaluate the effects of parboiled rice whole bran (PRWB) inclusion in laying diets for Japanese quails, on their performance, egg quality, and economic viability. A total of 448 17-week-old quails were weighed and distributed in a completely randomized design with seven treatments and eight replicates of eight birds each. A control diet (no PRWB) and six diets, containing 5, 10, 15, 20, 25, and 30% of PRWB, were tested. The increasing levels of PRWB did not affected nutrient digestibility coefficient, dietary energy use, feed intake, egg production, egg weight, egg mass, and the economic viability indices. However, there was a linear decrease in egg shell percentage, specific weight, and yolk color. The inclusion of up to...

ABSTRACT The objective of this study was to evaluate the effects of the supplementation of two xylanase products to diets with reduced metabolizable energy fed to meat-type quails during the starter phase (1-14 days). A completely randomized experimental design in a 2 x 3 + 1 factorial arrangement two reduced metabolizable energy (ME) diets, inclusion or not of xylanase, and a control diet with no enzyme addition) was applied, totaling seven treatments with five replicates of 45 quails each. At 14 days of age, jejunum segments were collected for morphometry evaluation. No interaction between the studied factors were detected for performance and jejunal morphometry parameters. Body weight, weight gain, feed intake and feed conversion were not influenced by...

Salmonella Enteritidis in the eggs of Japanese quails (Coturnix coturnix japonica - Temminck &amp;amp; Schlegel, 1849) fed diets with different calcium and phosphorus levels
Provedor de dados: 89

Several studies point out that eggs are the main cause of human salmonellosis, particularly when poorly processed or eaten raw. In addition of causing public health problems, the presence of Salmonella hinders international food trade, and therefore, it is a health barrier. There are several predisposing factors for the contamination of internal egg content by Salmonella spp, including eggshell quality, which is related to dietary calcium (Ca) and phosphorus (P) levels. In this study, eggs from Japanese quails fed diets containing two different Ca (2.0 or 3.5%) or P (0.25 or 0.45%) levels were evaluated. Three production phases were used in the experiment: starter, intermediate, and final. The presence of Salmonella Enteriditis in the eggshell and internal...

The use of carbon and nitrogen stable isotopes for the detection of poultry offal meal in meat-type quail feeds
Provedor de dados: 89
Autores: Sernagiotto,ER; Ducatti,C; Sartori,JR; Stradiotti,AC; Maruno,MK; Araujo,PC; Carvalho,FB; Pezzato,AC.
The objective of the present study was to trace the inclusion of poultry offal meal (POM) in the diet of meat-type quails reared for a long period using the technique of stable isotopes. A number of 320 quails were randomly distributed into eight treatments: vegetable diet (T1), and a diet containing 8% POM were fed until the end of the experimental period (T2) or replaced by the vegetable diet on day 42 (T3), 56 (T4), 70 (T5), 84 (T6), 98 (T7), and 112 (T8). Breast muscle samples were collected from four birds randomly selected per treatment every 14 days. The obtained isotope results were submitted to multivariate analysis of variance (MANOVA) with the aid of the GLM procedure of statistical SAS program. Treatments were different from T1 when birds were...

Effect of breeder age and storage conditions of Japanese quail eggs on hatchability, quail neonate quality, and Bursa of Fabricius characteristics
Provedor de dados: 96
Autores: Araújo,Itallo Conrado Sousa de; Mesquita,Mariana Alves; Café,Marcos Barcellos; Stringhini,José Henrique; Paz,Paulo Henrique Sousa da; Noleto,Raiana Almeida; Leandro,Nadja Susana Mogyca.
ABSTRACT Two experiments were conducted to evaluate combinations of different storage periods and temperature of hatching eggs of breeder quails in two stages of the production cycle (24 and 43 weeks) on hatchability, quail neonate quality, and Bursa of Fabricius characteristics. In each experiment, a total of 1.050 Japanese quail eggs were incubated in a randomized block design in a factorial arrangement of 2 × 5 × 2, with two breeder ages (24 and 43 weeks), five storage periods (one, three, six, nine, and twelve days), and two storage temperatures (28 and 14 °C), totaling 20 treatments with 52 eggs each. Quantitative data were subjected to ANOVA and means were compared by Tukey's test. Qualitative data were subjected to Friedman's test. Polynomial...

Xylanase for meat-type quails from 15 to 35 days old
Provedor de dados: 96
Autores: Grecco,Érica Travaini; Marcato,Simara Márcia; Oliveira-Bruxel,Taciana Maria de; Stanquevis,Caroline Espejo; Grieser,Daiane de Oliveira; Finco,Eline Maria; Zancanela,Vittor; Ferreira,Mariana Fátima Zanon.
ABSTRACT The objective of this study was to evaluate the effect of the supplementation of two xylanases in the diet of meat-type quail on performance, morphology of the intestinal mucosa, metabolization of nutrients, and carcass yield. The experimental design was a completely randomized 2×3+1 factorial arrangement [two metabolisable energy reductions (70 and 140 kcal/kg), with or without the inclusion of two xylanases (A and B), plus a control treatment without xylanase), totalling seven treatments with five replicates and 42 quail each. Total excreta were collected at 28 days of age to determine the metabolisable coefficients of dry matter, crude protein (CP), neutral detergent fibre (NDF), and gross energy (GE). There was no interaction between the...

Provedor de dados: 2
Autores: Gopinger, Edenilse; Moraes, Priscila de Oliveira; Catalan, Aiane Aparecida da Silva; Xavier, Eduardo Gonçalves; Castro, Martha Lopes; Schafhäuser Junior, Jorge.
A trial was conducted to evaluate the use of dehulled and unpolished whole rice in Japanese quails’ diet. A total of 100 80-days-old Japanese quails (149.07 ± 10 g) were distributed in five treatments: 0% dehulled and unpolished whole rice (control diet based on corn and soybean meal), 20, 40, 60, and 80% of whole rice in replacement of corn; respectively, treatments 1, 2, 3, 4, and 5. Productive performance was evaluated through egg production (%), egg weight (g), body weight (g), egg mass (g), feed conversion per egg mass and feed conversion per dozen eggs. The following variables measured the internal quality of eggs: albumen height (mm), yolk color and percentage, egg white percentage and Haugh units. The external quality of eggs was measured through...

Provedor de dados: 2
Autores: Vieira Filho, Javer Alves; Garcia, Edivaldo Antônio; Molino, Andréa de Britto; Santos, Tiago Atônio dos; Almeida Paz, Ibiara Correia de Lima; Baldo, Grace Alessandra de Araújo.
Two experiments were conducted at different times with the objective of investigating how the body weight of Japanese quails at the end of the rearing period may alter the performance during the laying phase. In both experiments, the birds were distributed in five treatments according to their body weights, which were obtained at 42 and 35 days of age for the first and second experiments respectively, and the following categories were considered for said experiments: very light, light, average, heavy and very heavy. For both experiments, the treatments were distributed in a randomized block design, at eight repetitions per treatment for the first one and six for the second one, both at 18 birds per repetition. During the first experiment, sexual maturity,...
