“…Nascimento et al (1992) showed that bacterial penetration is not related to eggshell pore numbers, and could be independent from changes in gas and water conductance of the embryo. Our results are generally in agreement with the study of Narahari et al (2000), who reduced EM by covering eggshell cracks with either resin, cellophane or insulation tape.…”

“…Traldi et al (2011) explained that CW is highly influenced by egg weight. Our findings are in close agreement with Narahari et al (2000), who applied different eggshell treatments (synthetic adhesive resin, cellophane or insulation tape) to cracked eggs. The CW/EW ratio was similar among the positive control (UE) and NV, CV and MP groups; and the average value (68.49 ± 0.40) was in line with the proportion (67%) proposed by Ross (2009).…”

“…A potential method for improving hatchability consists in sealing the eggshells with substances that reduce the impact of micro-cracks on embryo development. To this purpose, Narahari et al (2000) proposed the use of adhesive resin, cellophane tape, and insulation tape.…”

“…Kingori (2012) reviewed that more than 5% of eggs are not available for consumers, and 0.5-6% have eggshell damage. According to Narahari et al (2000), about half of the eggs rejected for shell defects shows micro-cracks, while the eggshell membrane remains undamaged. With regard to hatching, damaged eggshell alters the water balance and gas exchange between the embryo and the environment, favouring bacterial penetration (Solomon, 2010).…”

Background: Shell fragility of hatching eggs can have negative implications on the economic performance of hatcheries. Objective: To determine the efficacy of sealing eggshell micro cracks with either coloured or uncoloured nail varnish, and molten paraffin on hatchability, embryonic mortality (EM) and hatched chick weight (CW). Methods: Eggs (n= 576) with micro-cracks were assigned among four groups (n=144 each group) for a 21 d incubation period. One group was untreated (CE). In the other groups, the micro cracked area of eggshells was sealed with uncolored nail varnish (NV), colored nail varnish (CV), or molten paraffin wax (MP). A positive control group of un-cracked eggs (UE) was also included (n= 144). Results: The eggshell sealant treatments allowed normal conductance related to egg weight loss after 18 d of incubation (11.45%), and chick weights were normal among treatment groups (44.7 g). Hatchability and embryonic mortality in the early and late incubation periods of the NV group was similar to UE (84.02 vs 86.11% for hatchability, 6.95 vs 10.42% for EM on days 1-10, and 2.08 vs 1.39% for EM on days 18-21 respectively; p>0.05). The CV group had lower hatchability than the NV (77.77 vs 84.02% respectively; p<0.05), whereas MP showed similar hatchability compared to the CE group (59.72 vs 72.92%, respectively p>0.05). Conclusions: Application of uncoloured nail varnish on shell micro-cracks improves egg hatchability.

“…El peso de los pollos al nacimiento no mostró diferencia entre tratamiento, esto pudo ser a que ambos tratamientos provenían de la misma edad de reproductora; aunque guarda una relación directa con el peso del huevo y peso del saco vitelino (Barbosa, et al, 2012;Suárez et al;, Wilson, 1991Narahara et al, 2000). La edad de la reproductora afecta la incubabilidad, por lo que se tiene una relación lineal positiva conforme aumenta la edad de la reproductora y hay un aumento del tamaño del huevo, peso del pollo; más sin embargo hay una correlación lineal negativa entre la edad de la reproductora y la incubabilidad.…”

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.

Egg weight loss during incubation is a key indicator used to monitor successful egg development and is closely related to hatchability and chick survival. Artificial incubation is one of the most important captive breeding techniques used in conservation efforts to bolster avian populations. To repair damage to the eggshell and ensure embryonic viability during incubation, a variety of repair coverings can be applied. This study tested the impact of four repair materials (nail polish, synthetic glue, medical dressing, and molten wax film) on egg weight loss during incubation. We found no impact on weight loss for coverings smaller than 35% of the eggshell surface, nor did we find any differences between covering types. The average egg weight loss decreased as the coverage area increased, and the weight loss did not differ when blunt versus sharp‐end coverings were compared. Given the relative insensitivity of egg weight loss and survival to the type of patch material used, we concluded that the selection of material for the purpose of weight loss management could be based on practical considerations, such as ease of application and availability.
