Abstract: Mechanical vibrations are inherent to any system of transportation. In poultry production, the higher or lower intensity of this agent during the loading of eggs, chicks and chickens, can increase the production losses and decrease the efficiency of the system as a whole. However, despite its importance this factor is still unknown and little considered in the planning of the transport processes involved in the poultry industry. Therefore, the aim of raising the largest amount of data obtained so far to clarify the effects of mechanical vibrations already found in the transport of fertilized eggs, day-old chicks and broilers. A survey of international and national papers, from 1969 to 2014, which showed that the transport of fertilized eggs, the mechanical vibrations may be responsible for the incidence of cracks, in addition to promoting the agitation of internal constituents (yolk and albumen), which could potentially compromise the quality of birth and hatchlings. The transport of day-old chicks and broilers, the vibrations are related to situations of stress, discomfort and depreciation of the welfare of the birds, which still causes drops in the levels of glucose and corticosteroids and thus affect other parameters as the quality of the meat.

Key words: broiler chickens, fertilized eggs, Production losses, stress

 

Resumo: As vibrações mecânicas são inerentes a qualquer sistema de transporte. Na avicultura de corte, a maior ou menor intensidade deste agente durante o carregamento de ovos, pintos e frangos, pode aumentar as perdas produtivas e diminuir a eficiência do sistema como um todo. Todavia, apesar de sua relevância este fator ainda é desconhecido e pouco considerado no planejamento dos processos de transporte envolvidos na indústria avícola. Desta forma, objetivou-se levantar o maior número de dados obtidos até o momento para esclarecer e apontar os efeitos já encontrados das vibrações mecânicas no transporte de ovos fertilizados, pintos de um dia e frangos de corte. Foi realizado um levantamento de trabalhos internacionais e nacionais, de 1969 a 2014, os quais apontaram que no transporte de ovos fertilizados as vibrações mecânicas podem ser responsáveis pela incidência de trincas e rachaduras, além de promover o agitamento dos constituintes internos (gema e albúmen), o que possivelmente pode comprometer o nascimento e a qualidade das aves recém-nascidas. No transporte dos pintos de um dia e dos frangos de corte, as vibrações estão relacionadas com situações de estresse, desconforto e depreciação do bem-estar das aves, o que ainda provoca quedas nos níveis de glicose e corticosteroides e, consequentemente, prejudica outros parâmetros como a qualidade da carne.

Palavras-chave: frangos de corte, ovos fertilizados, perdas produtivas, estresse
