“…Many studies indicate that the hatch and the quality of broiler chicks are influenced by factors such as chickens' age and storage and transport conditions of hatching eggs (Tona et al, 2004;Reijrink et al, 2008;Salahi et al, 2012;Rocha et al, 2013). In this research, some of the results showed that the exposure of eggs to mechanical vibrations could also negatively affect the productive responses in hatchery facilities.…”

Many factors present in eggs' transportation from incubator to growing confinements can damage their integrity and, consequently, the results of the incubation. This study aimed to evaluate whether the intensity and duration of exposures of hatching eggs to mechanical vibrations were capable of affecting the hatch and the quality of broiler chicks. Four treatments, determined by two intensities of vibrations and two durations of exposures were evaluated and compared with a control group in a randomised design in blocks with four repetitions. The vibrations were applied by a mechanical shaker before incubation. Then the eggs were incubated and as the following responses were evaluated: hatchability, the type of embryonic mortality, the quality of the birds and the total of losses. The analyses were carried out by a binomial regression model, with application of the Wald test at 5% significance level. The results showed that the exposure of eggs to mechanical vibrations harmfully affects the hatchability and reduces the ratio (percentage) of high quality chicks. Highest vibration level together with longer duration of exposure resulted in worst hatchability and losses. It is argued that the mechanical vibrations are potentially damaging and should be regarded as an important factor in the management of hatching eggs.

“…For Tona et al (2004), day-old chicks represent the end product of the incubator and the starting material for broiler farms. Ulmer-Franco et al (2010) and Salahi et al (2012) explain that the birds' quality is the result of all the events that occur with the hatching eggs, before and during embryonic development.…”

“…Tona et al (2004) reported that chick quality affects the weight at slaughter age by a rate of 6.29% to 8.05%. Chick quality is under the influence of many genetic and environmental factors; however, Boerjan (2004) reported that the most important factor determining chick quality is the incubation conditions.…”

Stress based on high temperature and humidity reduces the production performance of fast-growing broilers and causes high mortality. Temperatures higher than optimum have been applied to broilers in the embryonic period in order to overcome thermal stress. This study was conducted to investigate the effects of exposure to two long-term high-thermal environments on the developmental stability of embryonic growth, hatchability and chick quality. For this purpose, 600 broiler eggs were incubated. Treatments consisted of eggs incubated at 37.8°C at 55% relative humidity throughout (control), heated to 39.6°C at 60% relative humidity for 6 h daily from 0 to 8th day, and heated to 39.6°C at 60% relative humidity for 6 h daily from the 10 to 18th day. Embryo weights and lengths of face, wing, femur, tibia and metatarsus were measured daily between the 10th and 21st day of the experiment. Daily relative asymmetry values of bilateral traits were estimated. The hatchability, the weight of the 1-day-old chicks and chick quality were determined. In conclusion, no negative effects of the treatments of the long-term high-thermal environment in the early and late stages of incubation for epigenetic adaptation were determined on the embryo morphology, development stability and weight of the chick. Moreover, regressed hatchability of embryos that were exposed to a long-term high-thermal environment was detected. Especially between the 10 and 18th day, the thermal manipulation considerably reduced the quality of the chicks. Acclimation treatments of high temperature on the eggs from cross-breeding flocks should not be made long term; instead, short-term treatments should be made by determining the stage that generates epigenetic adaptation.Keywords: epigenetic adaptation, heat stress, broiler, relative asymmetry, chick quality ImplicationsThe current study was performed to determine the effects of thermal manipulation on the developmental stability of the embryo, hatchability and chick quality. Negative effects of treatments of a long-term high-thermal environment in incubation were not determined on the embryo characteristics, but this treatment negatively affected both hatchability and chick quality. IntroductionAs a result of the long-term genetic improvement studies, the performance of broiler chickens has reached the current position (Baéza et al., 2012;Shaddel Telli et al., 2012). However, this development has led to an increase in sensitivity of the broilers to environmental factors, and has led to the weakening of their adaptability to adverse conditions (Uni and Yahav, 2010). The main environmental factors that cause loss of productivity and high mortality rates in poultry is heat stress, which is caused by high environmental temperature and humidity (Terim Kapakin et al., 2013). The feed consumption decreases in birds that are exposed to heat stress, and yield losses are experienced accordingly (Yalçin et al., 1997). In order to fight against heat stress, resistant genotypes should be developed through breeding, or the ...

RESUMOAvaliou-se a influência da classificação dos ovos no incubatório sobre a uniformidade, o desempenho e o rendimento de abate dos frangos de corte, utilizando-se 140 machos e 140 fêmeas nascidos de cada um dos seguintes tratamentos: A -ovos com pesos entre 66 e 72g, 33,3% deles originados de matrizes com diferentes idades; B -ovos com pesos entre 58 e 65g, 33,3% deles originados de matrizes com diferentes idades; C -ovos com pesos entre 52 e 57g, 33,3% deles originados de matrizes com diferentes idades; D -ovos com pesos entre 52 e 72g, produzidos por matrizes com 31 semanas; E -ovos com pesos entre 52 e 72g, produzidos por matrizes com 38 semanas; e F -ovos com pesos entre 52 e 72g, produzidos por matrizes com 43 semanas. O delineamento experimental foi inteiramente ao acaso, em esquema fatorial 6 x 2 (seis categorias de peso dos ovos x dois sexos), com quatro repetições
