“…The AME and AME n differed (P < 0.05) among treatments, ranging from 2909 to 3246 kcal kg −1 and 2877 to 3239 kcal kg −1 (Table 5), respectively. The values were lower than those found by Henz et al (2013) in five corn cultivars under organic fertilization for 21-day-old broilers, of 3113 to 3325 kcal kg −1 for AME and 3059 to 3287 kcal kg −1 for AME n .…”

The aim of this study was to evaluate the chemical composition, energy values and nutrient metabolizability coefficients of corn grown using different organic fertilizers and its use for feeding slow-growing broilers. Two experiments were conducted. In the first experiment, two hundred 21-day-old broilers were distributed in a completely randomized design, with five treatments and four replicates of 10 birds per experimental unit. The treatments were a control diet and four test diets (corn fertilized with crotalaria, corn fertilized with millet, corn fertilized with humus, and corn without fertilization), including corn at 30% in the control diet. The apparent metabolizable energy, apparent metabolizable energy corrected for nitrogen balance, and apparent metabolizability coefficients of dry matter, crude protein and gross energy were determined. In the performance trial, two hundred and fifty 1-day-old chicks were distributed in a completely randomized design into five treatments (T1 – control diet with commercial corn, T2 – corn without fertilization, T3 – corn fertilized with humus, T4 – corn fertilized with millet and T5 – corn fertilized with crotalaria) and five replicates of 10 birds per experimental unit. Weight gain, feed intake, feed conversion and final weight at 20 days were evaluated. The AME and AMEn values of corn fertilized with crotalaria, millet, humus and corn without fertilization were 3246 and 3239 kcal kg?1; 2965 and 2954 kcal kg?1; 2909 and 2877 kcal kg?1; and 3265 and 3201 kcal kg?1, respectively. The apparent metabolizable coefficients of DM, CP and GE were: 89.75%, 66.88% and 88.5% for corn fertilized with crotalaria; 84.38%, 58.73% and 81.4% for corn fertilized with millet; 80.38%, 53.45% and 78.95% for corn fertilized with humus; and 89.48%, 68.95% and 87.85% for corn without fertilization, respectively. Feeding broilers with corn cultivated with different fertilizers affected (P < 0.05) weight gain, feed intake, feed conversion and final weight. The treatments using corn fertilized with crotalaria, millet, humus and commercial corn did not differ, with better results in relation to corn crop cultivated without fertilization. The use of crotalaria and millet as a green manure, and humus derived from dairy manure are alternatives that can be used on corn crop as they resulted in grains with adequate nutritional composition, energy values and metabolizable coefficients for slow-growing broilers from 1 to 20 days of age.

“…In this regard, Henz et al (2013) reported that the moisture content of grains is considered an important parameter, because in high humidity conditions and long-term storage, as well as high environmental temperature, fungi contamination can occur, which produce mycotoxins that causes metabolic disorders in animals. The lowest CP obtained (6.85%) was lower than those presented by the National Research Council -NRC (2012) and Rostagno et al (2011).…”

The metabolizable energy (ME) determination for foods used in quail diets, through metabolism assays, takes time, infrastructure and financial resources, which makes the development of prediction equations based on proximal composition of foods to estimate the ME values of particular interest. The objective of this study was to adjust the prediction equations of metabolizable energy (ME) of corn for quail. The chemical compositions of 12 maize varieties were determined and a metabolism assay was carried out in order to determine the apparent metabolizable energy (AME) and nitrogen-corrected apparent metabolizable energy (AMEn) of these corn varieties. The values of chemical composition, AME and AMEn, converted to dry matter, were used to adjust the prediction equations. The initial adjustment of simple and multiple linear regression of the AME and AMEn was performed using the values of crude protein (CP), ether extract (EE), neutral (NDF) and acid (ADF) detergent fiber, mineral matter (MM), calcium (Ca) and phosphorus (P) as regressors (full model). To adjust the prediction equations the statistical procedure of simple and multiple linear regression was used, with the technique of indirect elimination (Backward). There was adjustment of 10 prediction equations, in which 5 were for AME and another 5 for AMEn and the R² values ranged from 0.20 to 0.75 and from 0.21 to 0.78, respectively. For all adjusted equations, negative correlations for MM were observed, which may be related to its dilutive effect of the gross energy contained in corn. In conclusion, the equations that showed better adjustment were AME= 5605. 46 -385 alimentos. Objetivou-se com este trabalho ajustar equações de predição dos valores de EM do milho para codornas de corte. Foi determinada a composição química de 12 diferentes cultivares de milho e realizado um ensaio de metabolismo, com estas cultivares, para determinação da EM aparente (EMA) e EMA corrigida para balanço de nitrogênio (EMAn).De posse da composição química, e dos valores de EMA e EMAn, convertidos para a matéria seca, procedeu-se com o ajuste das equações de predição. O ajuste inicial dos modelos de regressão linear simples e múltipla, dos dados de EMA e EMAn, foi realizado utilizando-se os valores de proteína bruta (PB), extrato etéreo (EE), fibras em detergentes neutro (FDN) e ácido (FDA), matéria mineral (MM), cálcio (Ca) e fósforo (P) como regressoras (modelo completo). Para o ajustamento das equações de predição, dos valores de EMA e EMAn, foi utilizado o procedimento de regressão linear simples e múltipla, por meio da técnica de eliminação indireta (Backward). Houve ajustamento de 10 equações de predição da EM do milho, sendo 5 para EMA e 5 para EMAn, cujos valores de R² variaram de 0,20 a 0,75 e de 0,21 a 0,78, respectivamente. Em todas as equações ajustadas observouse correlação negativa para a matéria mineral, o que pode estar associado ao seu efeito diluente da energia bruta contida nos milhos. Conclui-se que as equações que apresentaram melhor ajustamento foram...

“…The high costs of feeding broiler chickens has aroused interest in new alternative sources of food, which can partially replace energy and protein foods in the diet, aiming at minimizing the costs of nutrition and, consequently, production (FREITAS et al, 2017;HENZ et al, 2013;SILVA et al, 2017).…”

Aqui nós avaliamos a viabilidade da inclusão de glicerina purificada em dietas balanceadas para frangos de corte de 8 a 42 dias de idade. Para tanto, foram utilizados 160 fios de 8 dias de idade da linhagem Cobb 500®, distribuídos em delineamento inteiramente casualizado (CRD) com quatro tratamentos (0, 2, 4 e 6% de inclusão de glicerina purificada) e quatro repetições. de dez pássaros. Foram avaliados o consumo de ração, ganho de peso, rotação alimentar, peso final, biometria de coração, fígado, moela e intestino delgado, rendimento de carcaça, cortes especiais, coxa e sobrecoxa. de proteína e gordura. no músculo do peito.Os níveis de inclusão de glicerina purificaram nas dietas influenciaram (p <0,05) o ganho de peso, um peso alimentar eo peso de corte aos 42 dias, sem efeito (p> 0,05) sem consumo de ração (FI ). The same form, not much effect (p> 0. 05) nos income de carcaça e cortes especiais. Os níveis de inclusão de glicerina não são influenciados (p> 0,05) o peso relativo da moela, nem o peso e a duração do intestino delgado. No entanto, os níveis de inclusão de glicerina aumentaram os pesos do coração e do fígado (p <0,05).Os níveis de inclusão de glicerina purificada nas dietas não afetaram (p> 0,05) os valores de leveza (L *), vermelhidão (a *), amarelecimento (b *), pH ou proteína, mas aumentaram (p <0,05) a deposição de gordura no músculo do peito. Com base em nossos achados, propomos que a inclusão de 6% de glicerina purificada em dietas é tecnicamente viável para frangos de corte de 8 a 42 dias de idade. os níveis de inclusão de glicerina purificada afetaram os pesos relativos do coração e do fígado (p <0,05).
