Pre starter broiler nutrition
2020
espanolO experimento teve como objetivo avaliar o desempenho, peso relativo dos orgaos do trato gastrointestinal e morfometria do jejuno de frangos de corte aos 21 dias, alimentados com diferentes quantidades de racao pre-inicial. Foram utilizados 576 pintos de corte distribuidos em um delineamento experimental inteiramente casualizado, contendo quatro tratamentos, que consistiram do fornecimento de diferentes quantidades de racao pre-inicial (100, 200, 300 e 400 gramas), com seis repeticoes. Ao termino do consumo das respectivas quantidades de racao, as aves de cada unidade experimental passaram a receber uma racao inicial unica, a base de milho e farelo de soja, ate os 21 dias de idade. Os resultados obtidos foram submetidos a analise de variância e regressao polinomial ao nivel de 5% de probabilidade. Houve efeito linear crescente (P EnglishThe experiment aimed to evaluate the performance, relative weight of the organs of the gastrointestinal tract and morphometry of the jejunum of broilers at 21 days, fed with different amounts of pre-starter diet. 576 broiler chick were assigned in a completely randomized experimental design to four treatments, which consisted of providing different amounts of pre-starter diet (100, 200, 300 and 400 grams), and six replications and 24 birds per experimental unit. At the end of the consumption of the respective quantities of feed the birds in each experimental unit began to receive a ration based on corn and soybean meal, until the 21 days of age. The results were submitted to analysis of variance and polynomial regression to the 5% level of probability. The feed conversion rate linearly increased (P
