ABSTRACT

Objetivou-se avaliar a inclusão do resíduo da acerola em dietas de codornas de corte sobre o desempenho produtivo, rendimento de carcaça, biometria intestinal e viabilidade econômica das aves, aos 42 dias de idade. Foram utilizadas 400 codornas europeias, não sexadas, de um dia de idade, distribuídas em delineamento experimental inteiramente ao acaso, com cinco níveis de inclusão (0,0; 3,0; 6,0; 9,0 e 12,0%) de resíduo da acerola, com oito repetições e 10 aves por unidade experimental. Não foram observadas diferenças significativas (P>0,05) para o ganho de peso, o consumo de ração, a conversão alimentar, os pesos absolutos e os rendimentos de carcaça e os cortes nobres (peito, coxa e sobrecoxa). Houve efeito (P<0,05) linear para os pesos absolutos e relativos de fígado e moela. A biometria intestinal das aves não foi (P>0,05) influenciada pelos níveis de inclusão do resíduo de acerola. O resíduo de acerola pode ser utilizado como ingrediente alternativo nas dietas de codornas europeias, até o nível de 12% de inclusão, sem comprometer o desempenho produtivo, o rendimento de carcaça das aves e a viabilidade econômica.(AU)


The objective of this study was to evaluate the inclusion of the acerola residue in broiler quail diets on productive performance, carcass yield, intestinal biometry, and poultry economic viability at 42 days of age. Four hundred one-day unsexed European quail were distributed in a completely randomized experimental design with five inclusion levels (0.0, 3.0, 6.0, 9.0 and 12.0%) of residue of acerola, with eight replicates and 10 birds per experimental unit.No significant differences (P>0.05) were observed for weight gain, feed intake, feed conversion, absolute weights and carcass yields, and noble cuts (chest, thigh and sobrecoxa). There was a linear effect (P<0.05) for absolute and relative weights of liver and gizzard. The intestinal biometry of the birds were not (P>0.05) influenced by the inclusion levels of the acerola residue. The acerola residue can be used as an alternative ingredient in European quails diets up to a 12% inclusion level, without compromising productive performance, poultry carcass yield and economic viability.(AU)

ABSTRACT

A Pasteuria isolate associated with a population of the lance nematode Hoplolaimus galeatus was discovered in Peru. The infective propagules adhered to adult stages and juveniles and were found filling the bodies of males and females. The endospore and central core diameters measured 4.5 +/- 0.4 pm and 1.9 +/- 0.2 mum, respectively, which differed from those reported for other Pasteuria isolates found iu North America on the same host. Examinations of endospore ultrastructure with scanning electron microscopy showed the presence of a thin layer of parasporal fibers surrounding the central core, a thin reduced layer of parasporal fibers in contact with the host's cuticle, and a putative basal core ring.
