| O experimento foi realizado com o objetivo de avaliar o desempenho de codornas poedeiras alimentadas por diferentes períodos com milho moído ou ração de postura durante sete dias após três dias de jejum, método de muda utilizado. Após esse período, as aves foram alimentadas com ração de postura durante as 20 semanas do período experimental. Utilizou-se um delineamento inteiramente ao acaso com três tratamentos (ração de postura por sete dias, ração de postura por três dias e milho moído por quatro dias e milho moído por sete dias), e quatro repetições de 24 aves por parcela. Os resultados mostraram que aves alimentadas apenas com ração de postura nos sete primeiros dias após o jejum apresentaram maior produção de ovos nas seis primeiras semanas do período... |

| Objetivou-se avaliar as alterações físicas, produção de ovos e mortalidade de codornas poedeiras submetidas a muda forçada, durante um período de jejum. Utilizou-se um delineamento inteiramente ao acaso, com quatro tratamentos (0, 1, 2, e 3) dias de jejum, com três repetições de 36 aves por parcela. No início e ao final do período de jejum 2 aves por parcela foram abatidas, pesadas individualmente e sacrificadas para retirada e avaliação do ovário, oviduto, e fígado. Os resultados mostraram que no período de jejum de três dias houve uma redução de 25,64% no peso vivo, a produção de ovos caiu a 2,81% e a mortalidade foi de 4,60%. |

| This study aimed at verifying the possibility of replacing calcitic limestone by marine calcium in the diet of layers. A total number of 321 Hi-sex hens, with 40 weeks of age at the beginning of the experiment, was used. A completely randomized experimental design was applied, with 5 treatments (0, 15, 30, 45, and 60 % of calcitic limestone replacement by marine calcium source) and eight replicates of eight birds each. Treatments significantly affected specific gravity (p<0.05), with the inclusion of 60% marine calcium (T5) presenting the worst result as compared to T1, which included only calcitic limestone as calcium source. It was concluded that marine calcium can replace up to 45% of calcitic limestone with no effects on performance or egg quality. |

| ABSTRACT This study aimed at evaluating beak-trimming methods and intensities on the performance, beak length and uniformity, and egg parameters of commercial layers. During the rearing period, birds were distributed in randomized blocks, with a 2x3 factorial design + two treatments, consisting of beak trimming with infrared (IR) radiation (moderate or severe); three IR intensities (low: 42 nm, intermediate: 46 nm, or high: 52 nm); and two control hot blade (HB) beak trimming treatments (moderate or severe) with eight treatments and five replicates of 21 chicks each, totaling 840 birds. During the growing phase (second experiment) the factorial design was modified to 2 x 3 x 2 + 4, comprising two IR beak-trimming intensities (moderate or severe); three IR... |

| This study aimed at verifying if beak-trimming methods in Japanese quail pullets could optimize production by decreasing stress caused by cannibalism. A total number of 816 day-old Japanese quails was distributed in a completely randomized experimental design in a 2 x 3 factorial arrangement, with two beak-trimming ages (14 and 21 days of age) and three beak-trimming sizes (not trimmed, 1/3 trimmed, or 1/2 trimmed), and 4 replicates of 34 birds per replicate. Birds were submitted to the same management and feeding conditions. Weight gain, feed intake, feed conversion ratio, and mortality were evaluated. There was no significant effect of age at beak trimming on the evaluated parameters (P>0.05), as well as no significant interaction between age at beak... |

| The objective of this study was to evaluate the effects on gamma radiation levels on the physical and microbiological characteristics of chicken breast meat. A completely randomized experimental design in a 4x2x3 factorial arrangement was adopted. Treatments consisted of four radiation concentrations (0, 2, 4, or 8kGy), two package sealing methods (with or without vacuum), and three storage times (01, 07, or 14 days), with ten replicates each, totaling 240 chicken breast fillets. Packaging and radiation had no influence (p>0.05) on chicken breast meat pH, water retention capacity, or presence of Salmonella spp. Breast fillets not submitted to radiation and vacuum packed presented higher water retention capacity (p<0.05) than those radiated at 4kGy... |

| This study assessed the effect of different cage stocking densities on the performance of Italian quails in the laying period. Two hundred and sixty four quails with 30 weeks of age and 280g mean body weight were used. Birds were randomly assigned to 96 x 33 x 16 cm cages and distributed in a randomized block design with 4 treatments (12, 15, 18 and 21 quails per cage or 264, 211, 176 and 151 cm² per quail, respectively) and 4 replicates. Birds were given feed and water ad libitum and submitted to the same experimental conditions. The experimental diet was formulated based on NRC (1994) recommendations. There were no significant differences among treatments for feed conversion per egg mass (kg:kg), percentage of broken eggs and mortality. There was a... |

Foram utilizados 600 pintos machos da linhagem Ross, criados até 42 dias de idade, quando foram submetidos a três períodos de jejum (zero, quatro ou oito horas). A duração do período de jejum afetou (p<0,05) a perda de peso vivo, o rendimento de carcaça, carne de pernas, pés, conteúdo do papo e intestino. Aumentando-se o período de jejum até 4 horas, aumentou-se a perda de peso vivo e o rendimento de carcaça e patas, mas diminuiu-se o rendimento de pernas e o conteúdo do papo e do... |

| O experimento teve como objetivo estudar os efeitos de níveis de cantaxantina sobre o desempenho e a coloração das gemas dos ovos de galinhas poedeiras. Foram utilizadas 384 galinhas da linhagem Hisex Brown, em um delineamento em blocos ao acaso, contendo seis tratamentos (0, 12, 24, 36, 48 e 60 ppm de cantaxantina), com oito repetições de oito aves por parcela. O período experimental foi de 56 dias. A coleta de ovos foi realizada diariamente e a análise de coloração dos ovos foi efetuada com o abanico colorimétrico da Roche. Durante os 14 dias do período inicial do experimento, a melhor coloração das gemas foi obtida com a adição de 60 ppm de cantaxantina, atingindo-se a cor plateau de 14,3 do leque colorimétrico Roche aos 5,43 dias de inclusão do... |

A number of 360 72-week-old layers were submitted to forced molting. Upon return of lay (83 weeks of age), birds were distributed according to a completely randomized experimental design of six treatments with six replicates of 10 birds each. The control treatment consisted of 0.10% dietary supplementation of trace minerals from inorganic sources, which was proportionally replaced by five levels (110, 100, 90, 80, 70%) of an organic trace mineral supplement containing 30, 30, 40, 6, 0.61, and 0.3 g/kg product of Zn, Fe, Mn, Cu, I, and Se, respectively.
