Formulação de ração para frangos de corte de crescimento lento utilizando valores de energia metabolizável dos ingredientes determinada com linhagens de crescimento lento e rápido

Abstract: GO 3 Aluno de graduação − Instituto Federal Goiano Rio Verde -Rio Verde, GO 4 Aluno de pós-graduação −Instituto Federal Goiano − Câmpus Rio Verde -Rio Verde, GO RESUMOCom este trabalho, objetivou-se avaliar o efeito da formulação de rações para frangos de corte de crescimento lento, com a utilização de valores de energia metabolizável (EMAn) dos alimentos determinados por linhagens de crescimento rápido e lento, sobre o desempenho, características de carcaça, biometria de órgãos digestórios e valores energétic… Show more

“…The higher FC and lower FI in the 10% ASB treatment was due to the higher proportion of soybean oil and meal in the formulation (see Table 1), which provided energy, and initially stimulated but then reduced the FI. The addition of lipids in the diet promotes an increase in caloric density, the extra-caloric effect, which consists of the increase in nutrient availability of the feed ingredients, and the extra-metabolic effect of the fat that results in improvement of the energy efficiency through the increase in feed net energy (Sakomura et al 2004;Santos et al 2014).…”

“…We found no published studies that tested alternative ingredients for feed of slow-growth broilers in the initial phase up to 28 days, in which the birds remain confined without access to the picket. The vast majority of studies evaluate birds in the later growth phase, when breeding takes place semiextensively with free access to the picket for a large portion of the day until slaughter (Santos et al 2014;Veloso et al 2014;Tavares et al 2015). From a productivity point of view, ASB inclusion did not significantly affect weight gain and viability of the broilers in relation to the control, and the feed with 10% ASB inclusion resulted in significantly lower feed intake and lower feed conversion rate in relation to feed with 6% ASB.…”

“…Em decorrência das exigências nutricionais da categoria de aves estudada ainda demandarem de maiores esclarecimentos (NASCIMENTO et al, 2009) a composição nutricional da dieta controle associada a maior disponibilidade pode ter apresentado excessos que contribuíram para a maior deposição de gordura abdominal como reserva energética (SANTOS et al, 2014).…”

“…It is important to consider that there is a great divergence in the literature regarding the nutritional value of this feedstuff, which may change depending on the technological process to which it was subjected (25,26) ; the existing variations between the soils and climates where the wheat grain was cultivated; the species that will utilize it; environmental conditions; nutrient quantity and quality; and proportion relative to other nutrients, which may lead to alterations in its composition and digestibility, as well as other factors (27)(28)(29) .…”
