Economic traits and performance of Italian quails reared at different cage stocking densities Rev. Bras. Ciênc. Avic.
Faitarone,ABG; Pavan,AC; Mori,C; Batista,LS; Oliveira,RP; Garcia,EA; Pizzolante,CC; Mendes,AA; Sherer,MR.
This study assessed the effect of different cage stocking densities on the performance of Italian quails in the laying period. Two hundred and sixty four quails with 30 weeks of age and 280g mean body weight were used. Birds were randomly assigned to 96 x 33 x 16 cm cages and distributed in a randomized block design with 4 treatments (12, 15, 18 and 21 quails per cage or 264, 211, 176 and 151 cm² per quail, respectively) and 4 replicates. Birds were given feed and water ad libitum and submitted to the same experimental conditions. The experimental diet was formulated based on NRC (1994) recommendations. There were no significant differences among treatments for feed conversion per egg mass (kg:kg), percentage of broken eggs and mortality. There was a...

Traceability of animal meals in Japanese quail eggs using the technique of 13C e 15N* stable isotopes Rev. Bras. Ciênc. Avic.
Mori,C; Ducatti,C; Pizzolante,CC; Kakimoto,SK; Denadai,JC.
The objective of this study was to trace the inclusion of bovine meat and bone meal (BMBM) in the diet of Japanese quails by analyzing eggs and egg fractions (yolk and albumen) by the technique of carbon-13 (13C) and nitrogen-15 (15N) stable isotopes. In the trial, 120 Japanese quails were distributed in six treatments with four replicates of five birds each. The following treatments were applied: feed based on corn and soybean meal, containing graded BMBM inclusions (0, 1, 2, 3, 4 or 5%). After 42 days, 20 eggs per treatment were randomly collected for three consecutive days. Ten eggs were used for yolk and albumen sample collection, and ten for total egg sample collection. It was possible to detect the dietary inclusion of 1% BMBM in the egg and its...

Production performance and egg quality of quails (Coturnix japonica) during several periods of the day Rev. Bras. Ciênc. Avic.
Pizzolante,CC; Faltarone,ABG; Garcia,EA; Saldanha,ESPB; Deodato,AP; Sherer,MR; Mendes,AA; Mori,C; Pelicia,K.
Three experiments were carried out to analyze the performance and egg quality of Japanese quails throughout the day when submitted to different lighting programs. In each experiment, birds were submitted to a period of 28 days for adaptation to the lighting program. During the following three days, each day - from 7 am to 7 pm or 9 pm - was divided into six or seven periods of two hours each, and the remaining hours corresponded to another single period. All birds were submitted to the same management practices, and received water and feed ad libitum. The experimental diet was formulated according to NRC (1994) standards. It was observed lower feed intake in the period of 9 pm to 7 am, and a higher incidence of lay from 3 pm to 7 pm, as opposite to hens,...

Protein, methionine+cystine and lysine levels for Japanese quails during the production phase Rev. Bras. Ciênc. Avic.
Garcia,EA; Mendes,AA; Pizzolante,CC; Saldanha,ESPB; Moreira,J; Mori,C; Pavan,AC.
An experiment was conducted at Faculdade de Medicina Veterinária e Zootecnia/Unesp - Botucatu for 168 days to evaluate the effects of protein, Met + Cys and lysine diet levels on egg production and egg quality of laying Japanese quails. Quails with 42 days of age were reared in a completely randomized design. There were 1,944 quails distributed in four replicates of 27 birds per pen, according to a factorial 3x3x2 with three crude protein levels (16, 18 and 20% CP), three Met + Cys levels (0.700; 0.875 and 1.050%) and two lysine levels (1.100 and 1.375%). Birds fed diets with 18 and 20% CP had higher feed intake and egg production than those fed diets with 16% CP. There was significant interaction (p<0.05) between protein and Met + Cys levels on egg...

Emulsifier in broiler diets containing different fat sources Rev. Bras. Ciênc. Avic.
Guerreiro Neto,AC; Pezzato,AC; Sartori,JR; Mori,C; Cruz,VC; Fascina,VB; Pinheiro,DF; Madeira,LA; Gonçalvez,JC.
This present study aimed at evaluating the effect of the addition of an emulsifier to diets containing soybean oil, poultry fat or their blend, on the performance, carcass traits, serum lipid levels, pancreatic lipase concentration and nutrient digestibility of broilers. A randomized block design was applied using a 3 x 2 factorial arrangement, with three fat sources (soybean oil, poultry fat, and a blend of 50% soybean oil and 50% poultry fat) and the addition or not of an emulsifier. In experiment I, broiler performance, carcass traits, serum cholesterol, HDL, and triglyceride levels, and pancreatic lipase activity in 42-day-old broilers were evaluated. In experiment II, dry matter (DM), ether extract (EE), crude protein (CP) and crude fiber (CF)...
