“…Pedroso et al (2006) also reported 0.2% average weight loss per day of storage at room temperature in Japanese quail eggs, and losses greater than 0.6% on 3 and 6 days of storage. Moura et al (2008) observed higher weight loss in Japanese quail eggs stored at room temperature compared with those stored under refrigeration, and increasing egg weight loss with storage period, which reached 2.67% in eggs stored for 10 days.…”

Long storage periods may increase embryo mortality. The objective of this study was to evaluate the effects of storage period on the weight loss, eggshell surface temperature, hatchability, and embryonic mortality of Japanese quail eggs. Two hundred fertile eggs were collected from a flock of 30-week-old Japanese quails (Coturnix coturnix japonica). The eggs were collected for 10 consecutive days after lay, and immediately incubated. A completely randomized experimental design with 10 treatments, corresponding to the number of days eggs were stored between egg collection and setting, with 20 replicates each, was applied. Egg weight loss increased with storage period duration, starting on day 6 (2.1%, on average) and reached 3.26%, on average, in eggs stored for 10 days. The highest hatchability (p>0.05) was obtained in eggs stored for two days, which also lost the least weight (1.20%). Storage period did not influence eggshell surface temperature (p>0.05) during incubation, but higher temperatures (p<0.05) were measured on days 10 and 15 of incubation compared with day 5. Eggs stored for ten days presented the highest weight loss, and therefore, a storage period of up to five days is recommended to maintain the quality of incubated Japanese quail eggs. Furthermore, egg surface temperature increases during the second half of the incubation period as a result of increasing embryonic metabolic rate.

“…Animal Sciences Maringá, v. 38, n. 1, p. 87-90, Jan.-Mar., 2016 PVC package improved the yolk index during the first phase, and the yolk index and Haugh unit in the second phase, perhaps due to a lower liquefaction rate of albumen which hindered the yolk from absorbing water from the liquefied albumen (Figueiredo et al, 2011). Several studies showed that packaging may be highly efficient in protecting egg quality (Moura et al, 2008). However, it is not as efficient as refrigeration and it is not sufficient to mitigate the effect of storage at 25°C (Scatolini-Silva et al, 2013).…”

“…When eggs are inadequately packaged, the albumen's biochemical reactions occur faster and eggs become liable to contamination and to a shorter shelf-life (Moura, Oliveira, Thiebaut, & Melo, 2008).…”

ABSTRACT. Current assay evaluates the internal quality of eggs of Hy-Line W-36 hens, according to storage time, temperature and packaging. Two equal experiments, starting one day apart, were conducted with 140 eggs each. The two experiments were divided into two phases, from 1 to 9 days and from 9 to 21 days, in a randomized block design. In the 1 st phase, the treatments were arranged in a factorial 2 x 3+1, packaging (with or without), time (3, 6 and 9 days), with control on the 1 st day. In the 2 nd phase, treatments were arranged in a factorial design 2 x 2 + 1, packaging (with or without), cooling (with or without), and control on the 9 th day. Egg weight, albumen, yolk and shell percentage, yolk index and Haugh unit were evaluated. The internal quality was reduced (p < 0.05) during storage and the internal quality of eggs kept at room temperature decreased (p < 0.05), whereas eggs stored under refrigeration showed the same quality (p > 0.05) on the 9 th and 21 st days.Packaging assured better quality (p < 0.05), but not similar to the quality of refrigerated eggs. Results showed that the internal quality of the eggs was worse when there was no refrigeration during storage time and that packages provided better internal quality, although not as effective as cooling.Keywords: storage of eggs, type of packaging, Haugh unit.Qualidade interna de ovos de poedeiras comerciais em função do tempo, temperatura e embalagem de armazenamento RESUMO. Objetivou-se avaliar a qualidade interna de ovos de poedeiras comerciais da linhagem Hy-Line W-36 ® , em função da temperatura, tempo e embalagem. Foram conduzidos dois experimentos, que iniciaram com um dia de diferença, cada um com 140 ovos. Cada experimento foi dividido em duas fases, sendo de um a nove dias e de nove a 21 dias. O delineamento foi em blocos casualisados. Na primeira fase, os tratamentos foram arranjados em fatorial 2 x 3 + 1, embalagem (com ou sem), tempo (3, 6 e 9 dias), e um controle no primeiro dia. Na segunda fase, o arranjo foi 2 x 2+1, embalagem (com ou sem), refrigeração (com ou sem), e um controle no nono dia. Avaliou-se o peso do ovo, percentagem de albúmen, gema e casca, índice gema e unidade Haugh. A qualidade interna reduziu (p < 0,05) durante o armazenamento, e os ovos mantidos no ambiente apresentaram redução (p < 0,05) na qualidade interna, enquanto que os ovos sob a refrigeração apresentaram a mesma (p > 0,05) qualidade no nono e no 21º dia. A embalagem melhorou (p < 0,05) a qualidade, no entanto, não com a mesma eficiência que a refrigeração. Conclui-se que a qualidade dos ovos piora com o armazenamento se não houver refrigeração e a utilização de embalagem gera melhor qualidade interna, no entanto, não é tão eficaz quanto à refrigeração.Palavras-chave: armazenamento de ovos, tipo de embalagem, unidade Haugh.

“…080 ovos férteis) e com isto maiores perdas de água dos ovos férteis durante o transporte (Tabela 1). Vale lembrar que, quando a umidade relativa está acima da faixa ideal (55 -75%), tem-se o início da condensação sobre os ovos, que resultará em um ambiente mais propício para o crescimento de microrganismos (fungos e bactérias) nos ovos férteis (MOURA et al, 2008;PLETI et al, 2009;BARACHO et al, 2010;FREITAS et al, 2011;BARACHO et al, 2013). O período da primavera foi o que apresentou menor valor médio de umidade relativa, o qual foi registrado em 71,5%.…”

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.
