Aflatoxins Importance on Animal Nutrition
Mycotoxins are secondary metabolites produced by several fungal species, toxic to humans, animals and plants, and have been chemically characterized due to the activity of aflatoxins. Expand
Valine needs in starting and growing Cobb (500) broilers.
Based on the analysis of the starter phase data, it is concluded that the optimal digestible Val/Lys ratio for Cobb × Cobb 500 broilers is 77%, whereas for birds in the finisher phase (30 to 43 d of age), a digestible valine-to-lysine ratio of 76% is suggested. Expand
Digestible lysine requirements of broilers
Considering the most relevant broiler production parameters, in 22- to 35-d-old males, digestible lysine requirement for breast meat yield was higher than those for feed conversion ratio and weight gain. Expand
Digestible valine-to-digestible lysine ratios in brown commercial layer diets
Based on the evaluated parameters, the ideal digestible Val-to-Lys ratio is 92%, corresponding to 0.607% Digestible Val or 567 mg/hen per day of digestable Val. Expand
Estimation of optimal ratios of digestible phenylalanine + tyrosine, histidine, and leucine to digestible lysine for performance and breast yield in broilers
Based on growth and carcass parameters, the estimated ideal digestible ratios of Phe + Tyr, His, and Leu relative to digestible Lys were 112, 38, and 104%, respectively, for broiler chicks raised from 8 to 17 d of age. Expand
Effect of different levels of sunflower meal in diets on the performance of broiler chickens
The inclusion of 20% sunflower meal in the diet of broilers up to 42 days of age did not show harmful effects on performance and the economics viability, and the best economic performances were achieved when the birds were fed diets containing 5% sunflowers Meal in the starter phase, and 0% in the grower phase and total period.

Apparent metabolisable energy and amino acid digestibility of microalgae Spirulina platensis as an ingredient in broiler chicken diets
Overall, the metabolisable energy content and digestibility of AA for S. platensis indicated that the microalgae are potentially an alternative nutrient source for broilers, and the AIA method underestimated AME and AMEn in comparison to the total excreta collection method. Expand
A new species of Demidospermus Suriano, 1983 (Monogenea) parasite of gills of Auchenipterus osteomystax (Auchenipteridae), from the upper Paraná river floodplain, Brazil.
A new species of Demidospermus Suriano, 1983 is described from the gills of Auchenipterus osteomystax Miranda-Ribeiro, 1918 (Auchenipteridae), collected in the upper Parana river floodplain, Brazil.Expand
Inclusion of sunflower meal, with or without enzyme supplementation, in broiler diets
There was a significant increase in weight gain with the use of EC in the starter phase, which is possibly explained by the immature digestive system of birds at this age, and there were no SFM or EC significant effects on carcass or cuts yields. Expand
Spirulina platensis in Japanese quail feeding alters fatty acid profiles and improves egg quality: Benefits to consumers.
Microalgae in quail diets had positive effects on egg quality, and reduced levels of saturated fatty acids that are undesirable, and increased monounsaturated fatty acid levels that are beneficial to the health of consumers. Expand
