“…These results are similar to the ones found in literature (Lara et al, 2006;Duarte et al, 2010), which did not show any difference in the carcass characteristics of chickens fed with different fat sources.…”

“…They were then weighed and ground and the humidity, nitrogen, ethereal extract of excreta and ration contents were determined according to the methodology described by Silva and Queiroz (2002) to obtain the digestibility coefficient of dry matter (DCDM), nitrogen (DCN) and ethereal extract (DCEE). Crude energy was measured using a calorimetric pump (Ika ® -Werke, Model C2000), and the nitrogencorrected apparent metabolizable energy value (AMEn) was calculated using the equations proposed by Matterson et al (1965).…”

This research aimed to evaluate the interactions and effects of 2 and 4% addition levels of poultry slaughterhouse fat (chicken tallow) and soybean oil in diets for broiler chickens. Two experiments were carried out using one-day-old male Cobb chicks in an entirely random design with a 2x2 factorial scheme. In the first experiment, 560 chicks were used to evaluate performance and carcass characteristics. In the second experiment, 100 chicks were used to determine the nutrient digestibility, dietary energy utilization and the lipase and amylase pancreatic activity. There was no interaction between the fat sources and the addition levels for any of the analyzed variables, except for the digestibility coefficient of dry matter (DCDM), which was higher in diets added with 2% soybean oil when compared to chicken tallow. The addition of 4% fat in the diet, regardless of fat source, improved the digestibility coefficient of ethereal extract (DCEE) and increased weight gain and feed intake. Moreover, in the initial phase, the addition of 4% fat to the diet increased lipase activity when compared to diets with 2% addition, and a positive correlation between DCEE and pancreatic lipase activity was observed. In conclusion, there is no interaction between fat sources and addition levels, except for DCDM. Carcass characteristics are not influenced by any of the studied factors. The addition of 4% fat increases pancreatic lipase activity and improves DCEE, resulting in greater weight gain, regardless of the tested fat source, making chicken tallow a great alternative to soybean oil.

“…Therefore, the oils studied are digested similarly. Lesson and Summers (2001) state that the biochemical structure of the oils interferes with their digestibility, for example, the number of double bonds in the fatty acid, the carbon chain length, and if it is triglycerides or free fatty acid, which is confirmed by the results of this study.…”

Effect of corn oil on the digestibility and economic viability of broiler chicken feed, and on the bromatological composition of breast meat

et al. 2016

The objective of this study was to evaluate the digestibility, economic efficiency, and composition of breast muscle in broiler chickens fed with a diet containing corn oil as an alternative replacement to soybean oil. We evaluated feed digestibility, crude protein (CP), ethereal extract (EE), apparent metabolizable energy (AME), and apparent metabolizable energy corrected for nitrogen balance (AMEn) during two periods (17-21 and 31-35 days of age). An analysis of breast composition, feed cost (Yi), economic efficiency index (EEI), and cost index (CI) for live weight of the animal and carcass between the two oil sources was also carried out. The design was completely randomized in a 2×2 factorial design with two ingredients (soybean oil and corn oil) and two periods (17-21 and 31-35 days). Digestibility tests were performed with four replicates per treatment and two birds per pen, and tests of breast muscle composition were made with six replicates. There was an interaction between diet and age for digestibility of CP (P < 0.05), which was higher (P < 0.05) at 17-21 days using soybean oil. The digestibility of the feed was higher (P < 0.05) at 31-35 days compared to 17-21 days. The digestibility of EE was not affected (P > 0.05) by treatment or age. The use of corn oil resulted in higher (P < 0.05) AME in 17-21 day olds, and higher AME and AMEn in 31-35 day olds; there was no difference (P > 0.05) in AMEn among 17-21 day olds. In breast composition, there were no differences (P > 0.05) in deposition of EE. For CP level and dry matter (DM), corn oil showed better values, while for breast moisture, soybean oil resulted in higher levels of moisture compared to corn oil (P < 0.05). The economic viability analysis favored soybean oil. Our results suggested that corn oil can replace soybean oil in diets formulated with sorghum, since it has higher apparent metabolizable energy and resulted in better breast composition. ResumoObjetivou-se avaliar a digestibilidade, eficiência econômica e composição do músculo do peito de frangos de corte alimentados com ração contendo óleo de milho como alternativa de substituição ao óleo de soja. Foi avaliado a digestibilidade da ração, da proteína bruta (PB), do extrato etéreo (EE); energia metabolizável aparente (EMA) e energia metabolizável aparente corrigida pelo balanço de nitrogênio (EMAn); em dois períodos (17-21 e 31-35 dias). A análise da composição do músculo do peito, o custo da ração (Yi), índice de eficiência econômica (IEE) e índice de custo (IC) para peso vivo do animal e da carcaça entre as fontes lipídicas foi realizada no final da criação. O delineamento foi inteiramente casualizado em esquema fatorial 2 × 2 com dois ingredientes (óleo soja e óleo milho) e em dois períodos (17-21 e 31-35 dias). A digestibilidade foi realizada com quatro repetições por tratamento com duas aves por unidade experimental e para a composição do musculo do peito foi feito seis repetições por tratamento. Houve interação dieta e idade para a digestibilidade da PB (P < 0,05), que foi...

“…O sexo está entre os principais fatores de controle relacionados às características organolépticas (1) e o perfil de ácidos graxos da carne (2,3) de aves de corte criadas em sistema extensivo ou semi-intensivo. Segundo Souza et al (4) , o sexo, juntamente com outros fatores, contribui para as diferenças de textura, sabor, quantidade de gordura abdominal, pH final, capacidade de retenção de água e cor.…”

ResumoObjetivou-se caracterizar a qualidade da carne de aves da raça Rodhe Island Red em função da diferença do tipo de corte e sexo. Foram utilizadas 30 aves em delineamento inteiramente casualizado em esquema fatorial (2 x 2), sendo dois cortes (peito e coxa) e dois sexos, com cinco repetições por tratamento. As aves foram abatidas aos 105 dias para realização das análises físico-químicas, composição centesimal e perfil lipídico do peito e coxa. A coxa apresentou maior média de pH final, teor de vermelho (a*) e força de cisalhamento (FC). Para luminosidade (L*), o peito obteve a maior média e as fêmeas maior média de FC. A coxa apresentou maior teor de extrato etéreo (EE) e umidade. O peito apresentou maior média de ácidos graxos saturados. As fêmeas obtiveram maior quantidade de ω3 e menor relação ω6/ω3. Foi observado maior índice de trombogenicidade no peito. A coxa mostrou menor conteúdo de ácidos graxos saturados e menor índice de trombogenicidade. As fêmeas apresentaram maior teor de ω3. O tipo de corte demonstrou maior influência que o sexo sobre os parâmetros estudados e a coxa apresentou melhores aspectos físico-químicos e de perfil lipídico para carne de aves neste sistema de produção relacionados à qualidade de carne desejável pelos consumidores. Palavras-chave: ácido graxo; aterogenicidade; cor; força de cisalhamento; trombogenicidade. AbstractThis study aimed to characterize the quality of the meat from Rodhe Island Red poultry, considering the type of cut and sex. We used 30 birds in a completely randomized design in a factorial arrangement (2 x 2), two cuts (breast and thigh) and both sexes, with five replicates per treatment. The birds were slaughtered at 105 days to carry out the physical and chemical analysis, chemical composition and lipid profile of breast and thigh. The thigh showed the highest mean final
