| ABSTRACT This study was performed to evaluate the effects of the association of different digestible arginine and phytogenic additive dietary levels on performance and health status of brown-egg layers. In this study, a total of 504 33-week-old Hisex Brown layers were distributed into a completely randomized experimental design to a 4 × 3 factorial arrangement (dietary digestible arginine levels: 880, 968, 1056, or 1144 mg/kg of feed × phytogenic additive levels: 0, 100, and 200 mg/kg of feed) with six replicate cages of seven birds per cage. The phytogenic additive was composed of extracts of Baccharis dracunculifolia (40%), Astragalus membranaceus lipopolysaccharides (20%), cinnamon, and grape seed (20%). Feed intake was reduced when diets containing... |

| Foram avaliados métodos alternativos de restrição alimentar qualitativa em comparação à técnica convencional de muda forçada. Utilizaram-se 480 galinhas Babcock de 78 semanas distribuídas em três níveis de restrição alimentar (100, 75 e 50%) e três percentuais de redução de peso corporal (15, 20 e 25%), cada um com cinco repetições de 32 aves. Quando as aves atingiram o percentual de redução de peso corporal, determinaram-se o volume globular, os percentuais de ovário, oviduto, moela, intestino e gordura abdominal e o comprimento de oviduto. A partir do 28º dia e durante cinco períodos de 28 dias, observaram-se as características quantitativas e qualitativas de produção pós-muda. O maior período de restrição foi observado no nível de 50% e proporcionou... |

| The experiment evaluated the influence of isolated or associated phytogenic additives (PA) and organic acids (OA) on nutrient digestibility, performance and carcass characteristics of broiler chickens. Two experiments were conducted in a completely randomized design with a 2 × 2 + 1 factorial arrangement of treatments (with or without PA × with or without OA + antibiotic performance enhancer and anticoccidial). In the first experiment, two metabolic tests were conducted to determine the metabolizability coefficients of the nutrients of starter and growth diets. In the second experiment, 2520 one-day-old chicks were housed in 40 experimental units to evaluate the performance and carcass characteristics. The phytogenic additives and organic acids, isolated... |
