“…Lourenço da Silva (1994) stated that the embryo can use about 47% of the eggshell mass during the incubation period, since it provides approximately 80% of the calcium for skeleton formation after D10 (Peebles & Brake, 1985). In the present study, the most striking difference in eggshell thickness was observed on D13, which is consistent with the findings of Peebles et al (2001), who reported a decrease in eggshell weight of eggs produced by 27-and 36-wk-old breeders after D12.…”

Two experiments were carried out to study the effect of breeder age on incubation parameters (hatchability, eggshell thickness, egg surface temperature and chick weight). In Exp. 1, fertile eggs (30-and 60-wk-old breeders) were incubated at three different temperatures (36.8, 37.8 and 38.8 o C). Eggshell surface temperature was measured by attaching a thermocouple to the shell and data were collected in a datalogger every ten minutes. This study was conducted according to a 3 x 2 factorial design (three temperatures and two breeder ages). Data revealed that eggshell surface temperature changed according to incubation temperature, with the main increase occurring between 10 and 13 days of incubation, and that the maximum increase in eggshell surface temperature was not higher than +0.6 o C, irrespective of incubator temperature. The incubator temperature affected total incubation period and hatchability (%) at 38.8 o C, independent of breeder age. Heavier eggs resulted in heavier chicks, irrespective of incubator temperature. In Exp 2, the eggs (30-and 60-wk-old breeders) were incubated at 37.8 o C and eggs characteristics (weight, specific gravity, total hatchability and chicks weight) were evaluated according to a randomized experimental design. The data showed that breeder age affected eggshell thickness and chick weight (heavier eggs resulted in heavier chicks), but not specific gravity, eggshell surface temperature or hatchability. The findings of this study revealed that hatchability can be influenced by incubation temperature, but not by the breeder age. Breeder age can affect eggshell thickness, egg weight and eggshell surface temperature, but not specific gravity.

A total of 2000 Hubbard Classic females and 180 males (male to female ratio 1:11) close to standard body weights were selected and managed separately in the same shed. The objective of this experiment was to study the effects of egg size (small, medium and large) at mid (45 weeks) production cycle and flock age (30, 45 and 60 weeks old) on hatching egg weight loss, fertility, hatchability traits, chick weight and chick yield in a commercial Hubbard Classic broiler breeder flock. The results showed that minimum egg weight loss (P ≤ 0.05) was recorded in large egg size group at different incubation periods and egg weight losses decreased with advancing the age of breeder hens. Maximum fertility and hatchability (P ≤ 0.05) was noticed in small egg size group, followed by medium and large egg size groups. However, maximum embryonic mortality (P ≤ 0.05) during incubation and higher percentage of infertile eggs was recorded in large size egg group, followed by medium and small egg size groups. Low fertility, hatchability was recorded (P ≤ 0.05) in older hen at the age of 60 weeks. The chick weight and chick length were amplified (P ≤ 0.05) with increasing the egg size. However, egg size was not influenced (P ≥ 0.05) on chick yield. The chick weight, chick yield and chick length were improved (P ≤ 0.05) with advancing age of broiler breeder.

“…Los huevos deben de perder alrededor de 11 a 14 % de su peso original durante el proceso de incubación (Peebles et al, 2001;Suarez et al 1997;Decuypere y Michels 1992;Buhr, 1995;Prado et al 2001). La cutícula ha sido caracterizada como la barrera más externa del huevo para el control de microorganismos ambientales y el intercambio gaseoso y pérdida de agua, a través de los poros durante el desarrollo embrionario (Vick et al 1993;Nys et al, 1999).…”

“…En el presente estudio no se observó diferencia significativa, ya que se utilizó únicamente una edad de reproductora, sin que se afectara por la temperatura de bulbo húmedo (Barbosa et al;2012, French, 19971974;Fasenko et al;2001, Wilson, 1991Burh, 1995;Vick et al;1993;Arce, 1998). Aunque en el presente estudio no mostró diferencia significativa entre los tratamientos en las variables de mortalidad embrionaria, se puede apreciar que hay un aumento considerable de mortalidad embrionaria en los primeros días de incubación, puede ser asociado a las condiciones del manejo de todos los huevos en general, ya que la granja de reproductora se localiza a una distancia de 1 000 kilómetros de retirada de la planta incubadora; por lo que el transporte puede estar influyendo de manera significativa.…”

“…Por arriba o debajo de este punto, la viabilidad del embrión se puede ver disminuida y el porcentaje de nacimientos reducido (Michels, et al;1974;Meijerhof, 1992;Decuypere et al;1992;Phillips, et al, 1992;Suárez et al;French, 1997;Taylor, 1997;2001. El nacimiento de los pollos y el procesado posterior son cruciales para el desempeño productivo de las aves. Las aves de producción son los únicos animales que se transportan una vez que eclosionan, lo que hace que sea una experiencia importante en la vida de las aves.…”

Efecto de la humedad en incubación sobre la incubabilidad y mortalidad embrionaria del pollo de engorda en el trópico seco mexicanoEffect of incubator relative humidity on hatchability and embryonic mortality of broiler chicken in Mexican dry tropic RESUMEN El objetivo del presente experimento fue evaluar el efecto de dos humedades relativas (HR) en incubación sobre la incubabilidad y mortalidad embrionaria del pollo de engorda en trópico seco mexicano. Un total de 2,520 huevos fértiles incubables fueron divididos en dos tratamientos (1,260 huevos/ tratamiento), se colocaron en bandejas y se precalentaron. Los tratamientos se mantuvieron con 50 ± 2 %, y 58 ± 2 % HR. Se mantuvo la temperatura de ambas incubadoras a 37.7 ºC. Estas condiciones prevalecieron desde el día 0 hasta el día 19 de incubación. La pérdida de peso fue más significativa (P<0.05) con 50 % HR que a 58 % HR. El peso corporal e incubabilidad no se afectaron por la HR. La mortalidad embrionaria tuvo diferencias significativas en la primera semana con un aumento en la HR de 50 %, en las posteriores etapas de mortalidad embrionaria fueron iguales (P>0.05) a ambas HR. La pérdida de peso fue mayor con la HR de 50 %. Se concluye que ambas HR se pueden usar en incubación sin afectar la eclosión. Palabras clave: Incubabilidad, incubación, humedad relativa, mortalidad embrionaria. ABSTRACTThe objective of this experiment was to evaluate the effect of two relative humidities (RH) in incubator machine over hatchability and embryonic mortality of broiler chicken in Mexican dry tropics. A total of 2,520 incubating eggs were warmed at room temperature, they were weighed each one and divided into treatments (1,260 eggs/each) placed in trays and preheated. These treatments were maintained with RH to 50 ± 2 % and the other RH of 58 ± 2 %. The temperature in both incubators was kept at 37.7ºC. These conditions prevailed from day 0 until day 19 of incubation. Weight loss was more significant (P<0.05), with 50 % RH than 58 % RH. Body weight and hatchability were no affected by incubation RH. The data of embryo mortality had a significant difference in the first week with 50 % of RH, the other stage of embryonic mortality was equal (P>0.05) with both RH incubation. The eggs incubated at 50 % RH had increased weight loss in comparison with the other incubation RH. It is concluded that both HR can be used without affecting incubating hatching.
