“…In a study evaluating eggs stored for up to 35 days, Barbosa et al (2008) observed an average 9.20% reduction in the weight of eggs stored in a high temperature and moisture environment. Similar findings were reported by Figueiredo et al (2011), who verified greater egg weight loss, from 0.65g to 1.03g, in eggs stored at 21ºC for 5 and 10 days, respectively. Haugh units were affected by the interaction (p<0.01) between trace mineral source and storage period.…”

“…Oliveira et al (2009) observed greater losses in egg internal when eggs were stored at 25ºC compared with 6ºC for 30 and 50 days, respectively. Similar results were obtained by Figueiredo et al (2011) when storing eggs for up to 15 days at different temperatures (2.6ºC±0.9ºC and 25.6ºC±1.7ºC). There was no effect (p>0.05) of the evaluated treatments on raw yolk color.…”

Among the several factors required in breeding laying hens, debeaking is a factor that interferes with batch performance and affects animal welfare. Thus, the objective of this study was to evaluate three different debeaking procedures and to verify the best technique to be used. For this, the performance of the birds, the incidence of cannibalism, and in rearing phase, the quality of the eggs were evaluated. Dekalb White birds were distributed in a completely randomized design with three treatments, T1 (infrared radiation debeaking) T2 (hot blade debeaking) and T3 (V debeaking).The data was submitted to Analysis of Variance and compared by Tukey's test (95%), using statistical software R. The frequencies of mortality and cannibalism were submitted to the ChiSquare test (Software R). It was observed that mortality was lower with IR debeaking in the breeding phase. Already in the rearing phase, the mortality was similar between the debeaking techniques and the cannibalism was null. The final mean weight (g), mean weight gain (g) and average daily weight gain in the rearing and egg quality variables were higher for V debeaking when compared to other techniques. It is concluded that V-debeaking provides better bird performance, resistance and shell thickness when compared to the infrared radiations and hot blade debeaking, in addition to subjecting the birds to less stress.

“…A quantidade de cálcio depositada nos ovos permanece mais ou menos constante durante todo o ciclo de postura; todavia, do início ao final do ciclo de postura o ovo chega a aumentar até 40% do seu tamanho razão por que haverá menos cálcio por área de superfície de casca o que resultará na redução da resistência da casca; assim, aves jovens têm uma taxa de retenção de aproximadamente 60% enquanto as aves mais velhas retêm apenas 40% do cálcio absorvido (Oliveira et al, 2009;Costa et al, 2011;Figueiredo et al, 2011).…”

“…Sabe-se que a casca do ovo apresenta apenas 0,01 de água (Nascimento & Salle, 2003;Figueiredo et al, 2011). Portanto, a quantidade de água presente na casca do ovo era muito pequena para resultar em trincas.…”

Propôs-se, com esta pesquisa, avaliar a influência de diferentes idades das matrizes e tempos de estocagem no número de ovos trincados durante a operação de transporte em diferentes estradas. A pesquisa foi conduzida na empresa integradora avícola em Mogi-Mirim - SP, por meio do acompanhamento de três carregamentos em diferentes estações do ano (primavera, verão e outono). Foi utilizado um caminhão climatizado do tipo baú com capacidade para 592 caixas de ovos. Foram registrados, por meio de quatro acelerômetros, os níveis de vibração (m s-2) e choques em percursos realizados nas estradas de terra e asfalto. O número de ovos trincados foi obtido por meio da contabilização de 18 caixas de ovos transportadas que apresentavam três idades de matrizes e três tempos de estocagem, pelo método visual. Foi utilizado o delineamento experimental inteiramente aleatorizado com esquema fatorial 3 x 3. Conclui-se que as matrizes velhas e intermediárias apresentaram o maior número de ovos trincados; os maiores níveis de vibração e choques da carga ocorreram no sentido horizontal enquanto a estrada de asfalto ofereceu as piores condições para o transporte de ovos.
