ABSTRACT Were evaluated the effects of substituting limestone with quail eggshell powder on zootechnical performance, egg quality, and economic efficiency Japanese quails during peak production (11-20 weeks old). The experimental period was 63 days, divided into three 20-day periods. A completely randomized design used five treatments (0, 25, 50, 75, 100% substitution by powder), six repetitions, seven birds per unit, for a total 210 quails. Feed intake, egg/bird/day, bird housed, marketable...
The objective of this study was to evaluate the effects dietary supplementation purified lignin on performance, relative organ weights, serum metabolites, and gene expression profiles broiler chickens subjected cyclic heat stress (HS). At 22 days old, 280 broilers were distributed in a completely randomized design with four treatments, ten repetitions, seven birds per experimental unit. daily HS. A high temperature 32±1 °C maintained for 10 [...]
Objetivou-se avaliar a qualidade físico-química e sensorial de ovos galinha, mantidas sob piso, tratados superficialmente com óleo mineral, gelatina sem sabor 6% soluções própolis (15 20%) estocados refrigeração (Incubadora B.O.D: 7,9ºC 41,9% umidade relativa). Para o experimento físico-química, realizou um delineamento inteiramente casualizado em esquema fatorial 5 x (sem tratamento; 15%; 20%; durante cinco semanas estocagem) seis repetições quatro cada. Foram avaliados: perda peso dos (%);...
Resumo O estudo avaliou o efeito de diferentes doses fitase e duas dietas (milho farelo soja, farinha carne ossos) no desempenho frangos corte na digestibilidade nutrientes das rações. Foram utilizados 1320 Cobb 500 para experimento desempenho, 216 ensaio metabolismo, 252 pintos a determinação dos coeficientes aparentes estandardizados aminoácidos dietas. As aves foram pesadas individualmente distribuídos em delineamento inteiramente casualizado, totalizando seis tratamentos divididos...
Abstract The study evaluated the effect of different doses phytase and two diets (corn soybean meal, meat bone meal) on performance broiler chickens digestibility nutrients in feed. A total 1320 Cobb 500 broilers were used for experiment, 216 metabolism test, 252 chicks to determine apparent standardized coefficients amino acids diets. birds individually weighed distributed a completely randomized design, comprising six treatments divided into 2×3 factorial scheme (two three levels composing...
RESUMO No sistema de criação em piso as galinhas são criadas diretamente contato com o chão que pode ser coberto por diferentes tipos materiais. Objetivou-se avaliar ambiente térmico, comportamento, os índices zootécnicos e a qualidade ovos poedeiras dois piso, maravalha grama sintética. Foram utilizadas 120 da linhagem Hisex Brown®, destas, metade foi criada sobre outra sintética (Tapete Astro Turf®) distribuídas um delineamento inteiramente casualizado medidas repetidas no tempo,...
SUMMARY The current study aims to evaluate the zootechnical performance, quality of eggs, and immune system laying hen's upon supplementing their feed with flour mushroom Agaricus blazei. A total 210 Hisex Brown® hens, 67 weeks old, were distributed in a completely randomized design five treatments (control [0%], 0.04%, 0.08%, 0.12% 0.16% meal) seven replicates six birds per experimental unit. Were evaluated performance (feed intake, egg production [per day housed], marketable production,...
In this study, we evaluated how guanidinoacetic acid (GAA) addition in diets with various metabolizable energy (ME) contents affects the performance of broiler chickens. We also estimated equivalence GAA ME. distributed 1,280 one-day-old broilers a completely randomized design eight treatments, replicates, and twenty birds per experimental unit. Treatments were based on ME levels (2,775-2,875-2,975 kcal/kg; 2,850-2,950-3,050 2,925-3,025-3,125 or 3,000-3,100-3,200 kcal/kg, from 1 to 7, 8 21, 22 [...]
To estimate the ideal digestible (dig) Methionine (Met) + Cysteine (Cys):dig Lysine (Lys) ratio for broilers submitted or not to lipopolysaccharides (LPS) (E. coli) inflammatory challenge, 384 thirteen-day-old male chickens were distributed in a 4 x 2 (four ratios with without challenge) factorial completely randomized design, eight replicates per treatment and six experimental unit (EU). The unchallenged birds received an application of saline solution (SS). diets formulated meet...
