“…The metabolizable energy of corn oil (8,773kcal kg -1 ) approaches to soybean oil (8,790kcal kg -1 ; ROSTAGNO et al, 2011); in fact, NASCIF et al (2004) found that it is higher (corn oil: 8,666kcal kg -1 vs. soybean oil: 8,336kcal kg -1 ). BAIÃO & LARA (2005) reported additional values of 8,886kcal kg -1 (corn oil) and 8,790kcal kg -1 (soybean oil).…”

“…The oils and fats added to the diet of broilers greatly benefit their productivity; however, their use raises the final cost of feed (NASCIF et al, 2004). Nevertheless, corn oil (a by-product of the corn processing industry) has higher energy values than soybean oil (NASCIF et al, 2004;BAIÃO & LARA, 2005), and it is often extracted in large volumes by certain industries, resulting in a greater supply than demand.…”

“…Os valores de EMA e EMAn obtidos para o óleo de soja refinado, o sebo bovino, a gordura de suínos e a gordura de aves foram superiores aos determinados por Nascif et al (2004), trabalhando com pintos de corte mistos (8.672 e 8.827 vs 8.394 e 8.389;7.486 e 7.641 vs 7.333 e 7.329;8.555 e 8.674 vs 7.624 e 7.619;8.600 e 8.720 vs 8.587 e 8.579 kcal/kg de MS,respectivamente).…”

-MG. 4 DZO/UFLA, DZO/UFLA, Lavras -MG. RESUMO -O experimento foi conduzido para determinar os valores energéticos de 12 alimentos para codornas japonesas. Utilizaram-se 280 codornas com 19 semanas de idade, submetidas ao método de coleta total de excretas, em delineamento em blocos casualizados, com dez codornas por unidade experimental. O período experimental teve 32 dias de duração, dividido em quatro ensaios de oito dias, nos quais foram estudados dois grupos de alimentos (protéicos e energéticos), com cinco repetições cada um. Os grupos constaram de alimentos protéicos de origem animal (farinha de carne e ossos, farinha de peixe e farinha de penas e vísceras) e vegetal (farelos de soja 1 e 2) e alimentos energéticos de origem vegetal (milheto, sorgo e farelo de arroz integral) e óleo e gorduras (óleo de soja refinado, gordura de aves, sebo bovino e gordura de suínos). Os alimentos substituíram a ração-referência, à base de milho e farelo de soja, em 20% (protéicos de origem animal), 30% (protéicos de origem vegetal), 40% (energéticos de origem vegetal) e 10% (óleo e gorduras) na matéria natural (MN). Foram avaliados os valores de energia metabolizável aparente (EMA) e verdadeira (EMV) corrigidos pelo balanço de nitrogênio (EMAn e EMVn), e os coeficientes de metabolização da energia bruta (CMEB). As fontes protéicas estudadas, à exceção da farinha de penas e vísceras, apresentaram valores de EMAn superiores aos encontrados nas tabelas brasileiras para aves e suínos; a farinha de carne e ossos apresentou o maior CMEB (74,06%) e a de penas e vísceras, o menor (56,24%). Os alimentos energéticos avaliados, à exceção do sorgo, apresentaram valores de EMAn superiores aos referenciados nas tabelas brasileiras; o óleo de soja refinado e a gordura de suínos tiveram os maiores CMEB (95,81 e 93,32%, respectivamente), enquanto o farelo de arroz integral apresentou o mais baixo CMEB (61,13%).

Two hundred and eighty quails averaging 19 weeks old were submitted to the method of total feces collection as a randomized block design, with ten quails per experimental unit. The experimental period lasted 32 days, divided into four trials of eight days each, where two groups of feeds were studied (protein and energetic), with five replicates each: protein of animal origin (meat and bone meal, fish meal and feather and viscera meal) and plant (soybean meals 1 and 2), as well as energetic feeds of plant origin (millet, sorghum and whole rice bran) and oil and fats (refined soybean oil, poultry fat, beef tallow and swine fat). The feeds replaced the reference diet (corn, soybean meal-based diet), as-fed, in 20% (protein of animal origin), 30% (protein of plant origin), 40% (energetic of plant origin) and 10% (oil and fats). The values of apparent metabolizable energy (AME), true (TME), AME an...

“…Nevertheless, this ability develops quickly after the first days of life. (Table 3), which is dependent on the following factors: the length of the carbonic chain, the number of double bonds, the presence or absence of ester bonds (triglyceride or free fatty acid), the specific arrangement of the saturated and unsaturated fatty acids on the glycerol backbone, the composition of the free fatty acid, the composition of the diet, the type and quantity of triglycerides supplemented in the diet, the intestinal flora, the sex and age of the birds (Renner & Hill, 1961;Leeson & Summers, 2001, Nascif et al, 2004.

The terms fat and oil refer to triglycerides of several profiles of fatty acids. Fatty acids that are not bound to other organic components as glycerol are the so-called free fatty acids. Lipids constitute the main energetic source for animals and they have the highest caloric value among all the nutrients. Linoleic acid is the only fatty acid whose dietetic requirement has been demonstrated. Besides supplying energy, the addition of fat to animal diets improves the absorption of fat-soluble vitamins, decreases pulverulence, increases diet palatability, and the efficiency of utilization of the consumed energy. Furthermore, it reduces the rate of food passage through the gastrointestinal tract, which allows a better absorption of all nutrients present in the diet. The energetic value of oils and fats depend on the following: the length of the carbonic chain, the number of double bonds, the presence or absence of ester bonds (triglycerides or free fatty acids), the specific arrangements of the saturated and unsaturated fatty acids on the glycerol backbone, the composition of the free fatty acid, the composition of the diet, the quantity and the type of the triglycerides supplemented in the diet, the intestinal flora, the sex and the age of the birds. In birds, body fat composition is similar to the composition of the fat from the diet. The apparent digestibility of unsaturated fats is high in the first days of life of birds, whereas apparent digestibility of saturated fats is low. The quantity of oils or fats is assessed by the following methods: titration, moisture, impurities, unsaponifiable, saponification value, percentage of fat, percentage of free fatty acids/ acidity and the profile of fatty acids. The methods initial peroxide value, active oxygen method, osi, iodine value, and analysis of the thiobarbituric acid (TBARS) are specific to evaluate the oxidative stability. Considering diets with the same nutritive values, birds fed with rations containing oil present better performance than birds fed no oil. Moreover, the use of oil or fat in diets for broilers may change both the composition and the quality of the carcass.
