1. Effect of Hatching Time on Yolk Sac Percentage and Broiler Live Performance
ABSTRACT This study investigated the effects of broiler chick hatching time on the percentage of the yolk sac and subsequent broiler live performance. Broiler hatching eggs were obtained from a commercial flock at 55 wk of age and were stored for 2 d at 18°C and 75% relative humidity (RH) prior to incubation. Chicks were identified as hatching Early (471-47

2. Hatching Characteristics and Growth Performance of Eggs with Different Egg Shapes
ABSTRACT This study was carried out to identify the effect of the egg shape index on the hatchability, performance, and carcass yield of Japanese quails (Coturnix coturnix Japonica ). Eggs were incubated in three groups, according to three different egg shape index (SI) values (Group SI-I: 70.00-73.85%, Group SI-II: 73.86-77.71% and Group SI-III: 77.72-81.57

3. Effects of initial body weight and litter material on broiler production
This experiment was carried out in a 104 m² poultry house located between the geographical coordinates 25°45'00" south latitude and 53°03'25" west longitude and an average altitude of 550 m, from September to November, 2008. The chickens were placed in 12 pens measuring 2 m² each at a stocking density of 12 chickens m-2. This study aimed at evaluating th

4. Idade da matriz e período de armazenamento de ovos incubáveis no rendimento de incubação e desempenho inicial de poedeiras comerciais / Breeder hen ages and the storage period of the eggs over the incubation efficiency and starter performance
Two experiments have been carried out to evaluate the effect of the breeder hen ages and of the storage period of the eggs over the incubation efficiency and initial performance of laying hens. In the first experimental phase, 7224 Dekalb eggs with 32 and 57 weeks old, were incubated with three, five and seven days of storage. The treatments were defined acc

7. DESEMPENHO E PARÂMETROS REPRODUTIVOS DE DIFERENTES LINHAGENS DE CODORNAS JAPONESAS (Coturnix coturnix japonica) / Performance and reproductive parameters of different strain of japonese quail (coturnix coturnix japonica)
It was the objective of this study to evaluate the performance and reproductive parameters of different genetic groups of japanese quails between six and 26 weeks of age. There were used 384 japanese quails, assigned according to the experimental design (ramdomized blocks), considering the initial live weight of the birds as blocks in the beginning of the ex

8. Valores de energia metabolizÃvel de alguns subprodutos da agroindustria e sua utilizaÃÃo na alimentaÃÃo de frangos de corte / Values of energy metabolizÃvel of some of agroindustria by-products and their use in food for cutting of broilers
Two different studies were conducted in order to develop the present work. In the first, the objective was to determine the values of apparent metabolizable energy (AME) and nitrogen corrected apparent metabolizable energy (AMEn) of coconut meal (CM), cashew nut meal (CNM) and two types of sugar cane yeast (SCY1 and SCY2) for chicks and roosters. Two metabol

9. 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

10. Period of incubation and posthatching holding time influence on broiler performance
The present study had the objective of investigating the performance of broilers housed immediately after hatching or after a 12 or 24 hour of post-hatching holding time. One thousand and six hundred male Ross 308 broiler chicks with an initial body weight of 46 grams were used. These chicks were distributed in a completely randomized experimental design wit

11. Nicotinic acetylcholine receptor from chick optic lobe.
An alpha-bungarotoxin-sensitive nicotinic cholinergic receptor from chick optic lobe has been completely purified. Its standard sedimentation coefficient is 9.1 S. The value near 12 S reported for the related component from other brain regions can be reproduced when the initial extraction is by Triton X-100 (rather than Lubrol PX), but other protein is then

12. Ovalbumin Messenger RNA: Evidence That the Initial Product of Transcription Is the Same Size as Polysomal Ovalbumin Messenger
The messenger RNA for ovalbumin, the major secretory protein of the chick oviduct, appears not to be made as a high-molecular-weight precursor when artifacts due to aggregation are eliminated. No ovalbumin messenger RNA sequences that will hybridize to complementary DNA made against ovalbumin mRNA are found in concentrated samples of hen oviduct RNA larger t
