The objective of this study was to evaluate productive performance and egg quality of Japanese quails (Cortunix japonica) fed with synthetic and natural pigments. The treatments used were: 0.8% paprika extract (Capsicum annuum), 0.8% marigold flower extract, 4% paprika extract and 4% marigold flower extract and 0.045% synthetic pigment (Canthaxanthin) in feed. A total of 240 Japanese quails at 20 weeks of age were distributed in a completely randomized experimental design with five treatments and six replicates, with eight quails per experimental unit (30 experimental units). There was no difference (p > 0.05) for the evaluated parameters, except for yolk color which showed significant difference (p < 0.05) between the treatments used. The inclusion of 0.8% natural pigments in diet of Japanese quails can be used to substitute canthaxathin because it is effective on improving yolk color without affect performance and the quails egg quality.

The aim of this research was evaluate the productive performance, egg quality and the endoparasites presence on Carijo laying hens in Cage Free system, fed with two experimental diets, one of them supplemented with fresh banana leaf in natura. Were used 196 laying hens with twenty-four weeks of age, distributed in a completely randomized design with 14 boxes, two experimental diets and seven replicates, by treatment with fourteen birds per experimental unit. The variables analyzed were: feed intake; egg production; egg mass: feed conversion per egg mass; feed conversion per dozen eggs; egg weight; albumen weight; yolk weight; shell weight; yolk percentage; albumen percentage shell percentage; yolk pigmentation and the presence of endoparasites. No influence (p > 0.05) were found, for performance and egg production, in Carijo laying hens fed supplemented with banana leaf in natura. For the treatment with inclusion of banana leaf, yolk pigmentation were superior (p < 0.05) when compared to control diet, producing eggs with more yolks orange color. In respect to endoparasite analysis, there was significant effect (p < 0.05) in the percentage of infections present in excretas. Among the treatments evaluated, the one with banana leaf supplementation reduced in 26.54% the endoparasites presence. The inclusion of banana leaf in the diet of Carijo laying hens does not affect performance and eggs quality and decreases the amount of endoparasites of the genus Strogyloides spp.

The present study aimed to evaluate carcass, cut yields and gastrointestinal tract biometry, the meat quality and body lesions of broiler chicken fed with four levels of corn distillers dried grain with soluble in experimental diets. A total of 700 day-old mixed flock Cobb 500 broiler chicks were distributed in a completely randomized design with five treatments, seven replicates by treatment with 20 birds each. The experimental diets were controlled with crescent inclusion levels of DDGS (4, 8, 12 and 16 %). At 35 days of age 2 broilers from each lot was selected, weighted and identified with medium weight from the experimental unit for slaughtering and evaluation of cuts yield, carcass and gastrointestinal biometry. To evaluate hock lesions and broiler meat quality. Quadratic effect was observed in reference to the weight of the carcass and chest can be included the levels up to 11.29 percent and 6.16 percent respectively. For the other variables of income of casting, edible organs and not edible and there was no significant effect on gastrointestinal biometrics, only for the total size of the gastrointestinal tract there was quadratic effect being the level of 4.25% indicated for increased size of the organs. For all welfare and meat quality variables evaluated, there was no difference between the DDGS levels used in broiler diets and control diet. These findings means that the addition of up to 16 % DDGS in diets can be an alternative to feed chicken without inducing body lesions neither altering broiler meat quality.

Abst ractThe objective of this study was to evaluate different levels of inclusion of cottonseed meal in the diet of Japanese quail. Twenty Japanese quails were used in a completely randomized design consisting of five treatments and six replicates, with eight quails per replicate. The treatments used were: basal diet with 0% cottonseed meal; inclusion of 4% cottonseed meal, 8% cottonseed meal, 12% cottonseed meal, and 16% cottonseed meal. Feed intake per egg mass (kg/dz), feed conversion per egg mass (kg/kg), viability of birds, and weight gain were evaluated. The egg quality variables were: egg weight (g), yolk weight (g), eggshell weight (g) albumen weight, percentage of yolk, eggshell and albumen, and specific gravity (g/cm 3 ). Cottonseed meal in the diet influenced (P<0.05) individual feed intake (g/bird/day), yolk weight (g), albumen, and percentage of yolk, eggshell and albumen. No significant difference was observed for the other variables (P>0.05). Cottonseed meal can be added to the diet of Japanese quail without compromising performance or egg quality.

The main objective of this research is to evaluate the inclusion of different natural pigment solutions in diets formulated with maize and sorghum solutions on the growth performance and egg quality of commercial laying hens created in hot climates. Throughout the conduction of this experiment, were used 252 laying hens of the Hisex Brow, in a completely randomized design, with six treatments, seven repetitions, and six birds per plot. The experimental diets were assigned with different energy sources and adding pigmentation solutions, diet 1 (corn), diet 2 (corn + annatto), diet 3 (corn + carrot), diet 4 (sorghum), diet 5 (sorghum + annatto), diet 6 (sorghum + Carrot).  Afterward, being evaluated the performance and quality of eggs. It was observed significant difference with reference t egg production, egg weight (g), gem weight (g), the weight of shell (g), albumin in weight (g), and gem coloration (tons) among the treatments. There was no difference in the parameters of performance and quality of eggs evaluated, only the variable yolk color had a significant effect between treatments. Replacing the energy source of the corn diet with sorghum in the diet of laying hens at peak production provides similar performance and egg quality, which can be a substitute for quality and efficiency. The use of annatto and carrots as a natural pigmentation promotes greater pigmentation of the egg yolks of laying Hisex Brown eggs and does not impair the performance of the birds.
