Resumo: | The objective of this study was to increase the knowledge about the nutritional composition of maize grains and correlate the main physical and chemical variables that contribute to the energetic values of maize grains used in broiler rations. For this, corn grains samples received by a commercial broiler feed factory located in southeastern Goias during the years 2012 to 20015 were analyzed. The parameters evaluated were divided into physical variables such as: Moisture content (%),% (Kg / m³), chemical variables such as:% Ethereal Extract,% Crude Protein,% Crude Fiber,% Crude Grain,% Crude Grain,% Crude Grain,% Crude Grain and the presence of mycotoxins (Aflatoxin and Fumonisin. In the present work, the values, mean, median, maximum and minimum values, standard deviation, coefficient of variation and normality tests and data distribution were described for each physical and chemical variable analyzed. Where there was no normal distribution of the results during the experimental period, revealing variation of these variables. Significant correlations (P <0.05) were found between the physical variables, Density and Humidity (-0.76), Infested Grains and Presence of Fumonisin (0.81); Moderate among the variables Crude Protein and Presence of Fumonisin (0.63) and% of Good Grains and Broken Grains (-0.70); (-0.15), Presence of Aflatoxins (0.28),% Good Grains (0.33) and% of Broken Grains (-0.41), among the variables Crude Protein and (-0.23), Presence of Aflatoxins and% of Humidity (-0,30) and Fumonisins (-0,27), between Presence of Aflatoxins and% of Humidity ( 0.30) and Specific Density (0.28) and the Presence of Fumonisins with Specific Density (0.43). A metabolism test was also carried out with 400 broilers, 14 days old, of the Cobb 500 male lineage, to verify the influence of the specific gravity of the corn kernels on the values of Apparent Metabolizable Energy (AME), Apparent Metabolizable Energy corrected by nitrogen balance (AMEn), in natural and dry matter, Apparent Metabolizable Coefficient of Crude Protein (AMC_CP), Ethereal Extract (AMC_EE), Calcium (AMC_CA), and Phosphorus (AMC_P) were evaluated. For this purpose, different samples of maize with specific densities of 740, 760, 780 and 800 kg / m³ were obtained in a commercial feed factory for broilers, located in southeast Goias. The different fractions of specific density of maize had different bromatological compositions, with variations mainly in the Gross Energy (2.28%), Crude Fiber (21.6%), Ethereal Extract (16%) and Percentage of Infested Grains. The treatments were significant (P <0.05), on the values of AME, AMEn, AMC_DM, AMC_EE, AMC_CA and AMC_P, but did not have trend curve proportional to the stipulated variations for the specific density, not determining which fraction of corn would be of better nutritional quality. What alerts us to analyze all the physical and chemical characteristics of the grains, besides the specific density, in order to determine the quality of the corn received in the feed factory for broiler chicken. |

Para isto foram analisadas amostras à granel recebidas por uma fábrica de ração comercial para frangos de corte, localizada no sudeste goiano, durante os anos de 2012 a 20015. Os parâmetros avaliados foram divididos em variáveis físicas como: Teor de Umidade (%), % de Grãos Bons, % de Grãos Ardidos, % de grãos carunchados, % de grãos Chochos, % de Grãos Quebrados e Densidade Específica (kg/m³), variáveis químicas como: % de Extrato Etéreo, % de Proteína Bruta, % de Fibra Bruta e a presença de micotoxinas (Aflatoxina e Fumonisina). No presente trabalho foram descritos os valores, médios, mediana, valor máximo e mínimo, desvio padrão, coeficiente de variação e testes de normalidade e distribuição dos dados, para cada variável física e química analisada. Onde verificou-se não normalidade de distribuição dos resultados no decorrer do período experimental, revelando variação destas variáveis. Foram encontradas correlações significativas (P<0,05), altas entre as variáveis físicas, Densidade e Umidade (-0,76), Grãos Carunchados e Presença de Fumonisina (0,81); moderadas entre as variáveis Proteína Bruta e Presença de Fumonisina (0,63) e % de Grãos Bons e Grãos Quebrados (-0,70); baixas entre as variáveis Densidade e Extrato (-0,15), Presença de Aflatoxinas (0,28), % Grãos de Bons (0,33) e % de Grãos Quebrados (-0,41), entre as variáveis Proteína Bruta e % de Grãos Ardidos (-0,23) e Umidade (-0,13), Presença de Aflatoxinas e % de Umidade (-0,30) e Fumonisinas (-0,27), entre Presença de Aflatoxinas e % de Umidade (-0,30) e Densidade Específica (0,28) e da Presença de Fumonisinas com a Densidade Específica (0,43). Também foi realizado ensaio de metabolismo, com 400 frangos de corte, com 14 dias de idade, da linhagem Cobb 500, machos, para verificar a influência da densidade específica dos grãos de milho nos valores de Energia Metabolizável Aparente (EMA), Energia Metabolizável Aparente corrigida pelo balanço de nitrogênio (EMAn), nos Coeficientes de Metabolizabilidade Aparente da Matéria Seca (CMMS), da Proteína Bruta (CMPB), do Extrato Etéreo (CMEE), do Cálcio (CMCA) e do Fósforo (CMP). Para isto foram obtidas diferentes amostras de milhos com densidades específicas de 740, 760, 780 e 800 kg/m³, em uma fábrica de ração comercial para frangos de corte, localizada no sudeste goiano. As diferentes frações de densidade específica de milho, tiveram diferentes composições bromatológicas, havendo variações principalmente nos teores de Energia Bruta (2,28%), Fibra Bruta (21,6%), Extrato Etéreo (16%) e Percentual de Grãos Carunchados. Os tratamentos foram significativos (P<0,05), sobre os valores de EMA, EMAn, CM_MS, CM_EE, CM_CA e CM_P, porém não tiveram curva de tendência proporcional às variações estipuladas para a densidade específica, não determinando qual fração de milho seria de melhor qualidade nutricional. O que nos alerta para analisar todas as características físicas e químicas dos grãos, além da densidade específica, a afim de determinar a qualidade do milho recebido na fábrica de ração para frango de corte.Submitted by Luciana Ferreira (lucgeral@gmail.com) on 2017-01-12T10:15:20Z No. of bitstreams: 2 Dissertação - Lucas Ferreira Batista - 2016.pdf: 4705026 bytes, checksum: d0c97e3720b4867a1ed8298dcc3feb92 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-01-12T10:16:38Z (GMT) No. of bitstreams: 2 Dissertação - Lucas Ferreira Batista - 2016.pdf: 4705026 bytes, checksum: d0c97e3720b4867a1ed8298dcc3feb92 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-01-12T10:16:38Z (GMT).

description |
The objective of this study was to increase the knowledge about the nutritional composition of maize grains and correlate the main physical and chemical variables that contribute to the energetic values of maize grains used in broiler rations. For this, corn grains samples received by a commercial broiler feed factory located in southeastern Goias during the years 2012 to 20015 were analyzed. The parameters evaluated were divided into physical variables such as: Moisture content (%),% (Kg / m³), chemical variables such as:% Ethereal Extract,% Crude Protein,% Crude Fiber,% Crude Grain,% Crude Grain,% Crude Grain,% Crude Grain and the presence of mycotoxins (Aflatoxin and Fumonisin. In the present work, the values, mean, median, maximum and minimum values, standard deviation, coefficient of variation and normality tests and data distribution were described for each physical and chemical variable analyzed. Where there was no normal distribution of the results during the experimental period, revealing variation of these variables. Significant correlations (P <0.05) were found between the physical variables, Density and Humidity (-0.76), Infested Grains and Presence of Fumonisin (0.81); Moderate among the variables Crude Protein and Presence of Fumonisin (0.63) and% of Good Grains and Broken Grains (-0.70); (-0.15), Presence of Aflatoxins (0.28),% Good Grains (0.33) and% of Broken Grains (-0.41), among the variables Crude Protein and (-0.23), Presence of Aflatoxins and% of Humidity (-0,30) and Fumonisins (-0,27), between Presence of Aflatoxins and% of Humidity ( 0.30) and Specific Density (0.28) and the Presence of Fumonisins with Specific Density (0.43). A metabolism test was also carried out with 400 broilers, 14 days old, of the Cobb 500 male lineage, to verify the influence of the specific gravity of the corn kernels on the values of Apparent Metabolizable Energy (AME), Apparent Metabolizable Energy corrected by nitrogen balance (AMEn), in natural and dry matter, Apparent Metabolizable Coefficient of Crude Protein (AMC_CP), Ethereal Extract (AMC_EE), Calcium (AMC_CA), and Phosphorus (AMC_P) were evaluated. For this purpose, different samples of maize with specific densities of 740, 760, 780 and 800 kg / m³ were obtained in a commercial feed factory for broilers, located in southeast Goias. The different fractions of specific density of maize had different bromatological compositions, with variations mainly in the Gross Energy (2.28%), Crude Fiber (21.6%), Ethereal Extract (16%) and Percentage of Infested Grains. The treatments were significant (P <0.05), on the values of AME, AMEn, AMC_DM, AMC_EE, AMC_CA and AMC_P, but did not have trend curve proportional to the stipulated variations for the specific density, not determining which fraction of corn would be of better nutritional quality. What alerts us to analyze all the physical and chemical characteristics of the grains, besides the specific density, in order to determine the quality of the corn received in the feed factory for broiler chicken. |
