ABSTRACT We assessed the effects of different amounts of water-treated black tea waste (BTW) in the diets of laying hens on performance, egg quality, yolk peroxidation, and blood parameters in this study. The experiment lasted for 12 weeks, during which a total of 108 Lohman layers, of 24 weeks old, were randomly allocated to one of six dietary treatments (18 hens each); each treatment consisted of six replicate cages, each containing three hens. Experimental animals were fed a commercial diet that contained 0 (control), 20, 40, 60, 80, and 100% BTW in place of wheat bran. Providing BTW in diets for laying hens, instead of wheat bran, did not have a significant effect on egg production, egg weight, or body weight change. As the amount of BTW in the diet... |

Two hundred and fifty-two Hy-Line W36 laying hens were allotted in a completely randomized design with 6 treatments, 7 replicates and 6 hens per experimental unit in order to determine the ideal ratio of isoleucine (Ile) in relation to lysine (Lys) to laying hens aged 42-58 weeks. Experimental diets contained digestible Ile at different levels, resulting in different Ile:Lys ratios (0.73:1; 0.78:1; 0.83:1; 0.88:1; 0.93:1 and 0.98:1). A basal diet was formulated to provide Isoleucine in levels below recommendations. This diet was supplemented with L-isoleucine to make up the 6 diets. Each diet was made isonitrogenous by varying the dietary contents of glutamic acid and isocaloric by adjusting the contents of cornstarch. All essential amino acids were... |

RESUMO As rações dos animais monogástricos no Brasil constituem-se de milho e farelo de soja. Dentre os entraves do uso de grãos de cereais nas dietas destaca-se a presença de polissacarídeos não amiláceos, constituintes de baixa digestibilidade, não digeridos pelas aves. Desse modo, faz-se importância estudar ingredientes não convencionais e uso de aditivos, tais como as enzimas nas rações. Objetivou-se avaliar a produtividade e o metabolismo de codornas japonesas em postura, alimentadas com rações à base de milho ou sorgo contendo ou não xilanase e β-glucanase. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 2x2, sendo quatro tratamentos, com cinco repetições e sete aves em cada, perfazendo 140 animais. Os tratamentos foram:... |

The functional properties of foods can be preserved when they are coated with edible films, since both the loss of moisture and the transport of O2 and CO2 are reduced. The objectives of this work were: to compare weight loss, Haugh units, and albumen pH between fresh eggs and eggs coated with whey protein concentrate (WPC), under six storage periods (3, 7, 10, 14, 21 and 28 days), at 25°C. During the entire storage period, regardless of whether the eggs were coated or not, the Haugh unit values and the weight loss decreased, and differences between values from the first to the last period were lower for coated eggs. Albumen pH increased. The Haugh unit values for coated eggs were similar to those found in literature references when the same storage period... |
