“…incubation temperature is reduced during the hatching phase because the heating needs of the embryos are lower at this late stage of incubation (Decuypere & Michels, 1992;Molenaar et al, 2010). However, optimal incubation temperature during the hatching period of A. rufa has not been precisely established by scientific studies yet.…”

Game farming, hatching synchrony, incubation temperature, red-legged partridge.Submitted: May/2015 Approved: November/2015 ABSTRACTThis study aimed at investigating the effects of three incubation temperatures during the hatching period on egg weight loss, hatchability, chick weight at hatching and length of the incubation period of redlegged partridge (Alectoris rufa) under artificial incubation. One hundred and fifty eggs obtained from a red-legged partridge game farm were randomly allocated to three batches of 50 eggs each. Eggs were incubated at 37.8ºC during the first 20 days, and subsequently at 37.0, 37.4 or 37.8ºC until hatching. Fertility was 74.7% and a good hatching performance was obtained, characterized by 85.7% hatchability, 9.1% egg weight loss after 20 days of incubation, 13.8±0.1 g chick weight at hatching, and 23.2±0.1 days incubation length. Hatchability, egg weight loss after 20 days of incubation, and length of the incubation period were not affected by incubation temperature during the hatching period. However, hatching synchrony improved when the incubation temperature was increased from 37.0 to 37.8°C (p<0.05). Thus, hatching distribution became very leptokurtic and very positively skewed with the increase in incubation temperature during the hatching phase. In conclusion, higher hatching synchrony can be achieved in A. rufa when setting temperatures within the range 37.0 to 37.8ºC to incubate eggs during the hatching period. Consequently, incubation temperature management during the hatching phase may have a direct impact on hatching synchrony and hatchling management.

“…Dentro do contexto da incubação moderna, apenas recentemente foi reconhecido que fatores relacionados à incubação influenciam no desempenho e no crescimento de frangos de corte (DECUYERE et al, 2001;TONA et al, 2003). Portanto, é importante que o ambiente do incubatório tenha gerenciamento e manejo adequados e que seja homogêneo em todas as suas áreas, uma vez que a produtividade, assim como a qualidade do produto final, pode depender destas variáveis (DECUYPERE & MICHELS, 1992).…”

RESUMO:Este trabalho visou a quantificar as características de resposta produtiva de pintos de corte provenientes de duas linhagens comerciais, em incubatório de regime de estágio múltiplo. Para tal, foram monitorados três lotes de ovos férteis em incubatório comercial, verificando o impacto das seguintes variáveis ambientais: temperatura, velocidade do ar, umidade relativa, concentração de dióxido de carbono e presença de fungos. O acompanhamento de pintos provenientes de duas linhagens comerciais distintas (Cobb ® e Avian ® ) foi feito em três lotes, quando também foram coletados dados de perdas. A análise de componentes principais foi empregada para associar as variáveis de ambiente, produção e perdas, observando a magnitude dos vetores. Os resultados mostraram que o ambiente de incubação influenciou diretamente no desempenho (qualidade, incidência de anormalidades e mortalidade) das duas linhagens de frango de corte. Ambas as linhagens apresentaram perdas produtivas relacionadas à baixa temperatura de incubação na incubadora e no nascedouro, mostrando que a temperatura de incubação é o fator mais importante para que sejam alcançados índices produtivos ótimos. PALAVRAS-CHAVE: avicultura, incubação, ambiência. IMPACT OF ENVIRONMENTAL VARIABLES IN MULTI SETTER INCUBATION IN BROILER'S PRODUCTIONABSTRACT: This research aimed to quantify the characteristics of the productive response of pullets from two distinct genetic strains in multi setter incubator. For this three batches of fertile eggs were monitored in a commercial incubator verifying the impact of the following environmental variables: temperature, air velocity, relative humidity, carbon dioxide concentration and presence of fungi. The follow up was done in three flocks of broiler pullets from two commercial genetic strains (Cobb ® and Avian ® ) also along with the data of losses. The principal components analysis was used for associating the variables of environment, production and losses by observing the magnitude of the vectors. Results showed that the environment of incubation influenced the performance (quality, incidence of abnormalities and mortality) of the two broiler's strains. Both strains presented productive losses related to low temperature inside the incubator and in the hatchery showing that incubation temperature is the most important factor for reaching ideal productive index.

“…This reduction in temperature in the main rooms of the hatchery where the eggs have already been heated and embryos are developing can be harmful to the embryo. According Decuypere & Michels (1992), the embryo begins to develop at 24 ºC, and incubation temperatures higher of 39 °C or below 30 °C can be lethal to the embryos.…”

“…The incubation temperature is the most important physical factor affecting hatchability (Decuypere & Michels, 1992;van Brecht et al, 2005). Wilson (1991) determined that the optimal incubation temperature for chicken eggs is between 37 and 38º C.…”

The objectives of this study were to monitor the thermal environment of different hatchery locations during the transfer of fertile eggs from the setter and to the hatcher, to measure egg heat loss, and to determine its effects on hatchery results. In total, 1,728 fertile eggs of Cobb broiler breeders were divided into two treatments. In treatment 1 (T1), after 19 days of incubation, eggs were removed from the incubator and transferred to the hatcher in aninsulated box, and in treatment 0 (T0), eggs were transferred with no thermal insulation (T0). The duration of egg transfer was 10 minutes. Eggs were photographed using a thermographic camera at the exit of the setter, arrival at and exit from the candling room, and arrival at the hatcher. Based on the thermographic images, egg heat loss between these locations was calculated. At hatch, total hatchability, hatchability of fertile eggs, and hatchling weight were recorded and compared between T0 and T1. The temperature and relative humidity of the corridor between the setter and the candling room, of the candling room, of the corridor between candling roomand the hatcher were monitored using data loggers. The results indicated that T1 eggs lost 0.15 kJ less heat than T0 eggs during transfer. However, hatchability and hatchling weight were not affected by transfer treatment during the studies period.
