“…Quail breeders at 140 days of age produced eggs with higher average weight (p<0.05) and, consequently, heavier chicks at hatch. The results for chick weight at hatch are in accordance with those found by Corrêa et al (2011). These authors also observed that chicken quails originated from older breeders (270 days of age) presented lower (p<0.05) hatch weight.…”

“…Corrêa et al (2011) evaluated the effect of the interaction of breeder age (70, 205 and 280 days) with egg weight on the live performance of quails and verified that quails originated from heavier eggs and breeders with 205 and 280 days of age showed a better performance (p<0.05). The authors reported that the greater body weight and weight gain at 21 days of age was achieved in quails from breeders of 205 and 280 days of age.…”

“…The practice of classifying the eggs in the hatchery as a function of egg weight and breeder age of the breeder is due to the positive correlation between egg weight and chick weight. With this, it is possible to produce more uniform quail chick flocks that are easier to manage during the rearing period (Corrêa et al, 2011).…”

The influence of age (85, 140, and 270 days) of European quails breeders on the egg quality and hatching, fertility and progeny performance was evaluated. The experimental design was completely randomized in a 3x3 factorial arrangement (females' age x males' age), with ten replicates and six birds per experimental unit (four females and two males). Egg production and quality were determined during 3 periods of 14 days and incubation parameters were evaluated in eggs obtained in five consecutive days. The live performance of the progenies was analyzed until 35 days. There was no effect of male age or any interaction between the age of males and females for the evaluated variable. The female's age influenced egg production, egg weight and chick weight, with better results obtained for 140-d-old breeders. The age of females reduced the hatchability, increased the late mortality in incubated eggs, and had no effect on fertility, total embryo mortality or eggshell structure, when analyzed by electron microscopy. The number of sperm trapped in the outer perivitelline layer (sptz/mm²) was determined in 10 fertile eggs per experimental unit. Young females fertilized by young males (80 days) had reduced sptz/mm². Progeny live performance was not affected by breeder's age. Breeders with 270 days retain fertility; however, their egg production, weight and hatchability of fertilized eggs is reduced. In conclusion, European quail breeders with 140 days of age have better egg quality, hatching and breeding results.

“…Sabe-se que a idade da matriz influencia na perda de massa dos ovos férteis (TANURE et al, 2009;AKYUREK & OKUR, 2009;CORRÊA et al, 2011;SANTANA et al, 2013). Porém, quando esses ovos estão submetidos às condições microclimáticas de transporte adversas e densidades de caixas (ovos férteis) diferentes, as perdas de água dos ovos podem aumentar, independentemente da idade da matriz oriunda, como pode ser verificado na Figura 2.…”

RESUMO:Objetivou-se, por meio desta pesquisa, avaliar a perda de água de ovos férteis oriundos de diferentes idades de matrizes de corte e tempos de estocagem, durante o transporte. A pesquisa foi conduzida em uma empresa integradora avícola no Estado de São Paulo, por meio do acompanhamento de três carregamentos em diferentes estações do ano. Foram utilizadas diferentes densidades de caixas durante as três viagens. Porém, para o estudo da perda de água dos ovos, foi usado um total de 18 caixas contendo 4.320 ovos, em um caminhão climatizado. Estas caixas de ovos eram referentes às três idades das matrizes e aos três intervalos de tempos de estocagem; portanto, em cada viagem, foram transportadas seis caixas com 1.440 ovos. A caracterização microclimática do contêiner foi realizada por meio de 18 dataloggers no interior das caixas, os quais registraram temperatura do ar, umidade relativa e entalpia específica. A avaliação da perda de água dos ovos foi realizada através da massa de 140 ovos individualizados de cada tratamento. O delineamento experimental utilizado foi o inteiramente aleatorizado, com esquema fatorial 3 x 3. As condições microclimáticas das cargas transportadas para todas as estações estiveram acima das faixas ideais. Independentemente da idade da matriz e da condição do microclima, o aumento do tempo de estocagem leva a maior perda de água, assim como a piores condições microclimáticas. PALAVRAS-CHAVE:ambiência; operação pré-porteira; avicultura; perda de massa; ovos férteis. MICROCLIMATE, AGES OF BREEDERS AND STORAGE TIMES INFLUENCE ON WATER LOSS OF EGGS ON TRANSPOTATION?ABSTRACT: The objective of this research was to evaluate the influence of the storage period and breeder age on water loss during fertile eggs transport. The research was conducted in a poultry integrator company in the State of São Paulo -Brazil. Three shipments were evaluated in different seasons and box density. The study of egg water loss used a total of 18 boxes containing 4,320 eggs in acclimatized truck six boxes of each treatment that consisted of three storage periods -totalizing 1,400 eggs -per shipment. The microclimate characterization of the container was evaluated by 18 dataloggers inside the boxes, which recorded the following variables: dry-bulb temperature, relative humidity, and enthalpy. The evaluation of water loss eggs was performed by mass of 140 eggs of each individual treatment. The experimental design used was completely randomized with factorial scheme 3 x 3. The microclimate conditions of cargo transported for all seasons were above the upper optimum range. Regardless of breeder age and microclimate conditions, increased storage time leads to greater water loss, and worst microclimate conditions.
