    ABSTRACT: Dois experimentos foram conduzidos com o objetivo de determinar o valor energético do milheto (Pennisetum glaucum) ADR 7010 e avaliar o desempenho e a viabilidade econômica dos frangos de corte alimentados com rações contendo níveis crescentes de milheto ADR 7010. No Experimento 1 foram utilizados 72 frangos de corte com 21 dias de idade em um delineamento inteiramente casualizado com dois tratamentos, seis repetições de nove aves cada. A energia metabolizável aparente do milheto foi de 3.362,24 kcal kg-1 de matéria seca e 3.066,00 kcal kg-1 de matéria natural e o teor de proteína bruta de 12,6%. No Experimento 2 foram utilizados 960 pintos de um dia de idade, distribuídos em um delineamento inteiramente casualizado com seis tratamentos, cinco repetições e 32 aves cada. Os tratamentos consistiram de seis níveis de substituição do milhopelo milheto, variando de 0 a 100%. Observou-se efeito linear dos níveis crescentes do milheto sobre o ganho de peso e consumo de ração no período de 1-21 dias e no ganho de peso, no período de 1-41 dias de idade. Em rações isoenergéticas e isoaminoacídicas, omilho pode ser substituído pelo milheto ADR 7010 em nível de 100%, o que corresponde a cerca de 60% de inclusão de milheto nas rações para frangos de corte, sem prejuízos no desempenho das aves e com maior viabilidade econômica. Two experiments were carried out to determine the energy value, performance and economical feasibility of broiler chickens feeding on different levels of ADR 7010 pearl millet. Experiment 1was conducted by using 72 broilers with 21 days of age distributed in metabolism cages. A completely randomized experimental design was conducted, with two treatments, six replicates and nine broilers per experimental unit. Pearl millet replaced 40% of reference diet. Values of apparent metabolizable energy of ADR 7010 pearlmillet were 3,362 kcal kg-1 (as dry matter) and 3,066 kcal kg-1 (as feed basis) and 12.6% crude protein. Experiment 2 utilized 960 1-day-old chicks distributed in a completely randomized experimental design, with six treatments (0; 20; 40; 60; 80 and 100% ofpearl millet inclusion), five replicates and 32 birds per unit. A linear effect was reported of increasing dietary pearl millet levels on weight gain and feed intake in the starting period (1-21 days) and total period (1-41 days). The results were satisfactory for 100%replacement corn, meaning ADR 7010 pearl millet can be included at about 60% in broiler diets without compromising bird performance. Considering the performance results, pearl millet is economically efficient.

    ABSTRACT: The objective of this experiment was to evaluate the influence of Gln and vitamin E (VE) supplementation in the diet of broiler chickens (Cobb-Vantress) on the morphometry of the intestinal mucosa. The design was completely randomized in a 2 x 3 (VE x periods of administering Gln) factorial arrangement. The levels of VE used were 10 and 500 mg/kg of diet and 3 periods of administering (1%) Gln-supplemented starter diet (for the first 7 or 14 d of life or for no added Gln), totaling 6 treatments with 5 replicates of 50 birds per experimental unit. In the growth period (d 22 to 41 posthatch), the treatments consisted only in the respective levels of VE. On d 7, 14, 21, and 41 posthatch, 2 birds per replicate were killed, and samples of the duodenum, jejunum, and ileum were subsequently removed, fixed in Bouin solution, and later embedded in paraffin and stained with hematoxylin-eosin. The parameters analyzed were villus height and crypt depth. An ANOVA was applied to the obtained data, and the means were compared using Tukey's test (5% significance level). Greater development was observed in the duodenum, followed by the jejunum and ileum. On 41 d of life, diets with 10 mg of VE/kg supplemented with Gln (for the first 7 d of life) provided better development of the intestinal mucosa in broiler chickens.

    ABSTRACT: O objetivo deste trabalho foi determinar o efeito da utilização de um complexo multienzimático sobre o desempenho e qualidade dos ovos de poedeiras comerciais. Foram utilizadas 336 poedeiras comerciais, HyLine W36, com 29 semanas de idade distribuídas em um delineamento inteiramente casualizado com 7 tratamentos e 6 repetições de 8 aves cada. Os tratamentos consistiram de uma dieta basal suplementada com o complexo enzimático nos níveis de 400 ou 500 ppm com valorização do nível de proteína, energia metabolizável e aminoácidos do farelo de soja em 5/5/5, 7/7/7 e 7/7/9%, respectivamente. As variáveisestudadas foram: consumo de ração (g ave-1 dia-1), conversão alimentar (kg dz-1 de ovos), peso médio dos ovos (g), produção de ovos (%), gravidade específica (g mL-1), Unidade Haugh, coloração da gema, percentuais de sólidos totais, de gema, clara e casca (%),espessura da casca (mm) e composição bromatológica das excretas. A adição do complexo multienzimático apresentou resultados produtivos e de qualidade dos ovos semelhantes à dieta controle. The present study aimed to evaluate the effects of a commercial enzyme complex on the performance and egg quality of commerciallaying hens. A total of 336 29-week old Hyline W36 layers were allocated to a completely randomized experimental design with seven treatments and six replications of eight birds each. The treatments consisted of the basal diet supplemented with inclusion of (500 or 400ppm), overestimating the percentages of protein, ME and amino acids of the soybean meal by 5:5:5, 7:7:7 and 7:7:9, respectively. The studied variables were: feed intake (g bird-1 day-1), feed:egg (kg feed-1 egg dozen-1), egg weight (g), egg laying percentage (hen day-1) specific gravity (g ml-1), Haugh Unit, color of the egg yolk, total solids percentage (%), egg yolk percentage, albumen and eggshell (%), eggshell thickness (mm) and chemical compositionof hen manure. The inclusion of enzyme complex in the diet resulted in similar productive performance and egg quality compared to the control diet.

    ABSTRACT: The aim of this experiment was to determine the best level of salt for Japanese laying quails (Coturnix coturnix japonica). Three hundred and thirty-six quails with 13 weeks of age were housed in cages with 118 cm2/quail for 84 days (four cycles of 21 days each). The experiment was analyzed as a complete randomized design with seven treatments (0, 0.15, 0.20, 0.25, 0.30, 0.35, and 0.45% of salt) with six replicates of eight quails per pen. Every 21 days, the productive performance (% of production, feed intake and feed gain ratio [kg/kg and kg/dozen]) and egg quality (average egg weight, egg mass, eggshell percentage and thickness and Unit Haugh) were evaluated. Data were submitted to analyses of variance and regression, and the means, compared by Dunnett test at 5% of significance. Regression equation showed no treatment effect on productive performance. However, by the comparison among the means it was observed that the birds fed diet with salt addition showed higher values of performance and external egg quality than control (without salt). The 0.15% salt level (equivalent to 0.10% of Na and 0.12% of Cl) was sufficient to obtain these results.

    ABSTRACT: The objective of this trial was to determine the energy value of oat, barley, cassava residue and linseed grain (whole and milled) for Japanese quails (Coturnix coturnix japonica). Three hundred and sixty 40-d male quails were assigned to a completely randomized design with six treatments (reference diet + five feedstuffs), six replications and ten birds per pen. The total feces collection was the used methodology. The feedstuffs evaluated were used at a level of 20% replacing the energy source of the reference diet (RD) that was based on corn and soybean meal. The gross energy metabolization coefficient (GEMC) of oat, barley and linseed were higher than the cassava residue. The GEMC (%), apparent metabolizable energy (kcal/kg) and apparent correct metabolizable energy values for nitrogen (kcal/kg) were, respectively: 75.37; 3,425 and 3,395 for oat milled; 75.73; 3,253 and 3,198 for barley milled; 70.76; 2,312 and 2,316 for cassava residue; 76.53; 3,774 and 3,704 for linseed whole; 76.75; 3,955 and 3,929 for linseed milled.
