In the present study, we wil evaluete the effects of inoculation with probiotic or antibiotic on day 16 of incubation on metabolism, chemosensitivity (hypoxic and hypercapnic response), immune response to challenge with lipopolysaccharide (LPS) considering the microbiota-intestine-brain axis, and chick microbiota juveniles. To this end, fertile eggs from Cobb® lineage breeders will be sub…
The indirect calorimetry method, using the respirometry system, is employed for metabolic measurement in poultry birds, with the aim to evaluate the energy metabolism of poultry categories (broiler chicken. Laying hens, and broiler breeders) and the feed energy utilization of different feedstuff used un poultry production. The respirometry system proposed on the thematic project n. 2019/2…
This project aims to establish net energy (NE) system for poultry. It will be determined the requirements and NE values for feedstuffs. The indirect calorimetry method will be used to measure the energy metabolism (FHP, HP and RQ), this method has already calibrated in previous studies in our laboratory. Based on factorial approach, NE requirements will be partitioned into the maintenanc…
The book Incubation Managment will contain 26 chapters, which were written by brazilian and international profissionals, from universities and companies. The content of this book is related to the main advances of incubation knowledgements in the last ten years. Those advances have been relevant to the development of poutry production in Brazil and other countries. (AU)
This study aims to assess the effect of CO2 and broiler breeder age on embryonic development. 6.000 fertile eggs will be incubated according an at random experimental design in 2 x 3 factorial schedule, i.e, two breeders ages (40 and 59 wk) and 3 CO2 concentrations in the incubator (control, 10.000 ppm and 14.000 ppm) from the D1 to D10 (240 h of incubation). After that period the embryos…
The use of feed restriction is necessary to correct problems related to overweight in broiler breeders; however, very few data are available comparing the effect of different feeding programs on adipocite development and their implication on reproductive characteristics. Thus, this project aims to assess the effect of different feeding restriction programs and how they affect fat depositi…

This project aims to evaluate the effect of qualitative and quantitative dietary restriction and genetics on animal performance, carcass characteristics and major bacterial groups present in the digestive tract of broilers. Two experiments will be carried, the first with a commercial line of broilers, and the second with a slow growth line. All animals will be equality created until 21 da…
The use of feed restriction programs is necessary to correct problems related to excess weight in broiler breeders, however, little research has been conducted comparing the effect of different means of feeding on animals' adiposity and its implications on their reproductive traits. Thus, this project aims at evaluating the effects that different types of feed restriction program have on …
