“…These values were lower than those found by Bueno et al (2012), analyzing sorghum hybrids (3386 Kcal and 3250 Kcal), and Rostagno et al (2011), with 3189 Kcal for AME. However, the values were similar to those found by Santos et al (2013) evaluating the same sorghum cultivar used in this study (IPA 1011) for broilers at 14 days of age (2908 Kcal for AME and 2766 Kcal for AME n ).…”

The aim of this study was to evaluate the effects of sorghums grown with different organic fertilizers on the chemical composition, energy values, and nutrient metabolizability coefficients, as well as their use for feeding slow-growing broilers. Two trials were performed. In the first experiment, 200 21-dayold broilers were distributed in a completely randomized design (CRD), with five treatments and four replicates of 10 birds per experimental unit. The treatments consisted of a control diet and four test diets (sorghum fertilized with crotalaria, sorghum fertilized with millet, sorghum fertilized with humus, and sorghum without fertilization), including sorghum at 30% in the control diet. The apparent metabolizable energy (AME), apparent metabolizable energy corrected for nitrogen balance (AME n ), metabolizability coefficients of dry matter, crude protein, and gross energy were evaluated. In trial 2, 200 1-day-old chicks were used in a CRD with five treatments (T1 -control diet with commercial corn, T2 -sorghum fertilized with crotalaria, T3 -sorghum fertilized with millet, T4 -sorghum fertilized with humus, and T5 -sorghum without fertilization) and four replicates of 10 birds per experimental unit. Weight gain, feed intake, feed conversion, and final weight at 28 days were evaluated. The values of AME and AME n of sorghums fertilized with crotalaria, millet, humus, and sorghum without fertilization were 2894 Kcal kg -1 and 2881 Kcal kg -1 ; 2736 Kcal kg -1 and 2675 Kcal kg -1 ; 2727 Kcal kg -1 and 2694 Kcal kg -1 ; and 2994 Kcal kg -1 and 2959 Kcal kg -1 , respectively. The metabolizable coefficients of dry matter, crude protein, and gross energy were 76.04%, 42.01%, and 75.25% for sorghum fertilized with crotalaria; 77.50%, 50.77%, and 75.95% for sorghum fertilized with millet; 77.62%, 46.39%, and 75.54% for sorghum fertilized with humus; and 75.83%, 39.53%, and 74.71% for sorghum cultivated without fertilization, respectively. The dietary use of sorghum cultivated with different fertilizers did not affect (P>0.05) weight gain, feed intake, feed conversion, and final weight. Green manures with crotalaria, millet, and humus (bovine manure) are alternatives that can be used on sorghum crops because they resulted in grains with adequate nutritional composition, energy values, and metabolizable coefficients for slowgrowing broilers from 1 to 28 days of age. Key words: Alternative poultry farming. Productive performance. Metabolizable energy. ResumoObjetivou-se no presente trabalho avaliar o sorgo cultivado com diferentes adubos orgânicos sobre a composição química, valores energéticos, coeficientes de metabolizabilidade dos nutrientes e sua utilização na alimentação de frangos de crescimento lento.

“…A elevação dos valores de fibra nos tratamentos até o nível de 10% não foi capaz de influenciar o CR das codornas, a alta concentração de fibra na ração reduziu o aproveitamento de nutrientes e energia metabolizável, com consequente redução na taxa de crescimento e piora na eficiência alimentar. Dentre outros efeitos esperados da inclusão de fibra nas dietas está a diluição da concentração energética da dieta e a interação com a utilização dos demais nutrientes devido ao aumento da velocidade do trânsito digestivo (3) . A presença de fibra pode provocar a formação de uma substância gelatinosa que dificulta a absorção de nutrients e a formação dessa substancia está relacionada principalmente à fibra solúvel, que é composta em maioria pela hemicelulose (16) .…”

“…Na região nordeste (NE) do Brasil, esses ingredientes são onerados devido à distância dos principais centros produtores de grãos e problemas relacionados à logística. A redução de custos das rações é uma busca constante nas indústrias avícolas; dessa forma, promover estudos para tornar possível a substituição, parcial ou total, dos ingredientes mais onerosos de forma econômica é um fator que contribui para a viabilização da produção (3) . A agricultura irrigada e, mais especificamente, a fruticultura irrigada, promoveu um grande dinamismo na economia do NE e na estrutura urbana (4) .…”

<title>Resumo</title><p>Este experimento foi conduzido com o objetivo de analisar o desempenho e características de carcaça de codornas europeias alimentadas com resíduo da agroindústria da goiaba em substituição ao milho. Foram utilizadas 140 aves, distribuídas em um delineamento inteiramente casualizado. Os tratamentos consistiram em uma ração controle e quatro rações com níveis de inclusão 2,5; 5,0; 7,5 e 10,0% de farelo de goiaba em uma ração à base de milho e farelo de soja. Não foram observadas diferenças significativas (P>0,05) para as variáveis: ganho de peso, consumo de ração, conversão alimentar, eficiência alimentar, peso e rendimento de carcaça e cortes nobres (peito, coxa e sobre-coxa) asas, dorso, pescoço cabeça, pés e órgãos comestíveis (coração, fígado e moela). O farelo de goiaba pode ser utilizado como ingrediente alternativo nas dietas de codornas europeias, no período de 16 a 38 dias de idade, até o nível de 10% de inclusão, sem deprimir o desempenho produtivo e rendimento de carcaças das aves.</p>

“…The treatment was divided randomly into the following groups with different feed preparation: Group A: addition of zinc bacitracin at 100g/ ton of feed; Group B: addition of BthTx-I at 20 mg/kg of feed; Group C: feed with no addition of antimicrobial agent. Feed formulations were made up according to the nutritional requirements proposed by Santos et al (2013). The broilers were monitored until the 28th day for the observation of possible effects of the experiment conducted during the fourth week of breeding.…”

Bacterial resistance is a sanitary issue explained by indiscriminate use of nonprescription drugs, and antimicrobial use in food production for growth promotion. Bothropstoxin-I (BthTx-I) is a phospholipase A2 (PLA2) from Bothrops jararacussu venom, which has a known antimicrobial effect. The goal of this study was the unprecedented evaluation of in vivo antimicrobial activity of BthTx-I in broilers. Microbiological, biochemical, and histological parameters were determined using 84 21-day old broilers that were kept in cages with four birds each at a density of 625 cm2/broiler. The experiment was randomized by three treatments with seven repetitions of four broilers each that lasted seven days. The treatments were: 1) bacitracin zinc diet; 2) PLA2-BthTx-I; 3) without additives. The data obtained from the studied variables was subjected to analysis of variance and an F-test at the 5% significance level. Averages of each variable in each treatment were compared by Tukey’s test. Broiler bacterial cloacal counts showed that BthTx-I decreased the microbial population without reducing body weight, intestinal morphology, or liver or kidney histopathological damage. The toxin showed in vivo activity, being an alternative for better performance in the production of broiler chickens, because it acted by decreasing the microbial load of potentially pathogenic bacteria in the intestinal microbiota of the birds and did not cause muscle, liver or kidney damage at the assessed dosage.
