Different incubation temperatures of Cobb-500 fertile eggs and their effect on weight loss and chick weight performance
The investigation was of an inductive nature supported by observation and recording techniques, it was established with four treatments T1 37.2 °C; T2 37.5°C; T3 37.8 °C and T4 38.00 °C, distributed in a completely randomized design (DCA). 1552 Cobb-500 eggs were incubated to evaluate the effect of different temperatures on incubation weight loss and chick weight performance. The variables were measured: weight loss in incubation (%), first quality chicks (%) hatchability of fertile (%), chick weight bb (gr) and chick weight yield (%). The percentage of weight loss in incubation showed significant differences (p < 0.05), where T4 presented the greatest weight loss (13.67%) compared to T1, which obtained 9.29%. No significant differences (p > 0.05) were found for first-time chicks and fertile hatchability. The percentage of yield in weight of the chick in relation to the initial weight of the egg showed significant differences (p < 0.05), since T1 is the treatment with the highest yield with 74.03% compared to T4 that reached 69.41%. It is concluded that the temperature variation in incubation influences the parameters; egg weight loss during incubation, and chick weight performance in relation to Cobb 500 egg weight, but it does not influence the production of prime chicks and hatchability.

La investigación fue de corte inductiva apoyada en las técnicas de observación y el fichaje, se estableció con cuatro tratamientos T1 37,2 °C; T2 37,5 °C; T3 37,8 °C y T4 38.00 °C, distribuidos en un diseño completamente al azar (DCA). Se incubaron 1552 huevos Cobb-500 para evaluar el efecto de diferentes temperaturas en la pérdida de peso en incubación y el rendimiento en peso del pollito. Se midieron las variables: pérdida de peso en incubación (%), pollitos de primera calidad (%) incubabilidad de fértiles (%), peso de pollo bb (gr) y rendimiento en peso de pollito (%). El porcentaje de pérdida de peso en la incubación evidenció diferencias significativas (p < 0,05), donde el T4 presentó la mayor pérdida de peso (13,67%) frente al T1 que obtuvo el 9,29%. No se encontró diferencias significativas (p > 0,05) para pollitos de primera e incubabilidad de fértiles. El porcentaje de rendimiento en peso del pollito con relación al peso inicial del huevo mostró diferencias significativas (p < 0,05), ya que T1 es el tratamiento con mayor rendimiento con 74,03% frente al T4 que alcanzó 69,41%. Se concluye que la variación de temperatura en la incubación influye en los parámetros; pérdida de peso de los huevos durante la incubación, y el rendimiento de peso en pollitos con relación al peso de huevos Cobb 500, más no influye en la producción de pollitos de primera y la incubabilidad. A investigação foi de natureza indutiva suportada por técnicas de observação e registo, foi estabelecida com quatro tratamentos T1 37,2 °C; T2 37,5°C; T3 37,8 °C e T4 38,00 °C, distribuídos em delineamento inteiramente casualizado (DCA). 1552 ovos Cobb-500 foram incubados para avaliar o efeito de diferentes temperaturas na perda de peso de incubação e no desempenho de peso do pintinho. As variáveis foram medidas: perda de peso na incubação (%), pintos de primeira qualidade (%) incubabilidade de férteis (%), peso do pintinho bb (gr) e rendimento de peso do pintinho (%). A porcentagem de perda de peso na incubação apresentou diferenças significativas (p < 0,05), onde T4 apresentou a maior perda de peso (13,67%) em relação a T1, que obteve 9,29%. Nenhuma diferença significativa (p > 0,05) foi encontrada para pintinhos de primeira vez e eclodibilidade fértil. A porcentagem de rendimento em peso do pinto em relação ao peso inicial do ovo apresentou diferenças significativas (p < 0,05), pois T1 é o tratamento com maior rendimento com 74,03% em relação ao T4 que chegou a 69,41%. Conclui-se que a variação de temperatura na incubação influencia os parâmetros; perda de peso do ovo durante a incubação e desempenho do peso do pintinho em relação ao peso do ovo Cobb 500, mas não influencia na produção de pintinhos nobres e na eclodibilidade.
