1. Physical-Chemical and Sensorial Quality of Eggs Coated With Copaiba Oil Biofilm and Stored At Room Temperature for Different Periods
ABSTRACT The present study aimed at evaluating the effects of a coating based on copaiba oil on the quality of eggs stored for different periods. Eggs were coated with copaiba oil solutions (4, 8, 12, 16, or 20% copaiba oil) or not (control) and stored for 1, 7, 14, 21, 28 or 35 days at room temperature. The following parameters were evaluated: egg weight lo

3. Effect of Egg Weight on External and Internal Qualities, Physiological and Hatching Success of Japanese Quail Eggs (Coturnix coturnix japonica)
ABSTRACT This experiment was conducted to evaluate the effect of egg weight and egg physical characteristics on embryonic development, hatchability, and hatchling weight of Japanese quails (Coturnix coturnix japonica). In total, 689 eggs were classified in two categories: small (<13.5 g) or large (≥13.5 g), and different external eggshell and internal qual

4. Physical-Chemical Characteristics of Designer and Conventional Eggs
ABSTRACT The objective of this study was to compare the internal and external quality of conventional and designer eggs. In total, 120 Tetra SL laying hens were randomly allotted to two treatments (K and P groups), with 12 replicates of five hens each. The control group (K) was fed a standard layer diet, producing conventional eggs, and the P group was fed a

5. The inclusion of coffee in commercial layer diets
This experiment aimed at evaluating the effect of the dietary inclusion of caffeinated and decaffeinated coffee on the performance and internal and external egg quality of commercial layers. One hundred and twenty 25-week-old Hy-line Brown layers, with 1575 ± 91 average body weight, were distributed according to a completely randomized experimental design w

11. EFEITOS DAS DIFERENTES RELAÇÕES CÁLCIO:FÓSFORO DISPONÍVEL E FITASE SOBRE O DESEMPENHO PRODUTIVO, QUALIDADE DOS OVOS E TECIDO ÓSSEO DE POEDEIRAS DE OVOS DE CASCA MARROM / EFFECT OF RELATION CALCIUM:PHOSPHORUS AVAILABLE AND PHYTASE ON THE PERFORMANCE, EGGS QUALITY AND TIBIA ASH OF BROWN EGG LAYING HENS
Two experiments were conduced to the effect of relationship between calcium and phosphorus available (8/1; 11/1 and 14/1) in diets based on maize and soybean meal. Each experiment used 144 brown egg layer (UFSM V and UFSM P strain) from 28Th to 36Th weeks of age. The evaluated parameters had been body weight, fed intake, fed efficiency, egg production, album
