The effects of stocking density of eggs and larvae were studied related to the morphological deformities appearance, percentage of survival, and growth rate, in order to achieve the most suitable stocking density for eggs and larvae in incubators and rearing tanks. The egg stocking densities were 500, 700 and 900 g per incubator for great sturgeon, 500 and 1000g per incubator for Persian sturge...

Previous techniques that have been used to monitor broiler embryonic temperature and metabolism during incubation either have been invasive to the embryo or have not directly determined internal egg temperature. Therefore, the current investigation was conducted to determine the earliest day of incubation on which temperature transponder implantation in the egg air cell could be performed with ...

to study the putative transfer of antibiotic resistance from broiler breeders to human, hen’s eggs and theirday-old chicks were examined for the presence of bacteria. the most frequently isolated organisms indecreasing order were: streptococcus spp., bacillus spp., staphylococcus spp., klebsiella spp., enterobacterspp. and escherichia coli followed by citrobacter spp., proteus spp. and pseudomo...

A closed colony of Lutzomyia longipalpis was established with specimens collected in the Raposa - Serra do Sol indian reservoir, one of the main foci of visceral leishmaniasis in the State of Roraima, Brazil. Biological observations were made on four generations of a L. longipalpis colony with emphasis on productivity. Aspects studied were the number of laid and retained eggs, and the number of...
