Efeitos da energia da dieta sobre desempenho, rendimento de carcaça e gordura abdominal de frangos de corte

Abstract: Um experimento foi realizado com o objetivo de avaliar o efeito do nível de energia da dieta sobre desempenho, rendimento de carcaça e porcentagem de gordura abdominal de frangos de corte. Foram utilizados 2400 pintos de um dia da linhagem Ross 308, criados em boxes até 42 dias de idade. O delineamento experimental adotado foi o inteiramente casualizado em esquema fatorial 6 x 2 (energia x sexo). Os tratamentos consistiram de combinações de seis níveis de energia (2.900, 2.960, 3.020, 3.080, 3.140 e 3.200 kcal… Show more

“…The founded results are correlated to those discussed by MENDES et al (2004) during 1-21 days. VASCONCELOS & SANTOS (1997) and NASCIMENTO et al (1998) also reported improvements in GAIN and FCR with increased dietary levels of energy; however, reported no differences for feed at this stage.…”

“…A conversão alimentar (Tabela 7), tanto dos machos quanto das fêmeas, nos períodos de 1 a 40 e de 1 a 45 dias de idade não foi influenciada (P>0,05) pelos níveis Tabela 6 -Consumo de ração (g) em frangos de corte machos e fêmeas nas fases de 1 a 40 e de 1 a 45 dias de idade Mendes et al (2004), que observaram pior rendimento de coxa+sobrecoxa quando fornecidos níveis mais baixos de aminoácidos.…”

“…Levels of substitution of corn for babassu flour mesocarp (%) CV Replacement of corn with babassu mesocarp flour in balanced rations for broilers in the period from 1 to 21 days Energy is one of the limiting factors of consumption and the broilers regulate their feed intake primarily to meet their energy requirements (MENDES et al, 2004). The experimental diets were formulated to be isocaloric (2950 kcal/kg) in order to meet the requirements (kcal / kg) of poultry regardless of the level of substitution of corn with the BMF, which may explain the absence of effects on the feed consumption of the birds.…”
