1. Post-hatch fasting and infectious bronchitis vaccination affect growth, gastrointestinal development, and morphometric parameters of the small intestine of broiler breeders up to three weeks of age
ABSTRACT The influence of fasting and vaccination against infectious bronchitis (IB) on growth, gastrointestinal development, and morphometric parameters of the small intestine of newborn broiler breeders was investigated. Weight gain (WG), feed conversion ratio (FCR), gastrointestinal visceral growth, residual yolk sac, and morphometric parameters of the sm

2. Performance of Chicks Submitted to Fasting Post-Hatching and with Maltodextrine Supplementing to Diet as Hydrating and Energetic Additive
ABSTRACT This study aimed to evaluate the effect of maltodextrin on performance of chicks passed through four fasting periods. A completely randomized design was performed, consisting of three treatments (1 - control, 2 - 4% saccharose; 3-4% maltodextrin 20) and four fasting periods after hatching (0, 12, 24 and 36 hours) with four replications, totaling 192

3. Influence of sex, age, and fasting on blood parameters and body, bursa, spleen and yolk sac weights of broiler chicks
The effects of water and feed fasting for 24, 48 and 72 hours post-hatching on blood parameters (mean corpuscular volume, MCV; red blood-cell, RBC; hematocrit, HCT; hemoglobin, HGB; plasma glucose, CGP; plasma total protein, PP, and differential leukocytes count), and on body, liver, spleen, bursa, and yolk sac weights were analyzed. Erythrogram data were ob

4. Desempenho de frangos de corte influenciado pela idade da matriz, tempo de incubação e manejo pós-eclosão / Broiler performance influenced by broiler breeder age, incubation period and post-hatching handling
Foram realizados 4 experimentos com o objetivo de avaliar distribuições de nascimentos em função da idade da matriz, e as conseqüências de períodos prolongados de permanência das aves no nascedouro sobre seu futuro desempenho, procurando estabelecer novos manejos que busquem melhorias na qualidade do pintinho. Observou-se que a idade da matriz interf
