Resumo: A comparison was made of the egg yolk pigmentation produced by two comercial products, Carophyll red (10% canthaxantin) and Pigmenting Complex 1131 (streptoxanthin). The colour of ten yolks a day per treatment was determined over an experimental period of 20 days using a Roche Colour Fan and a Hunter Lab Colour & Colour Difference Meter. The results show that pigment deposition first appeared in the yolks of eggs laid on the 5th day of treatment. Both pigmenting sources were significantly different at the 1% level from the control group but there was no difference between them. The correlation between the two methods of measurement was highly significant.

Foram utilizadas galinhas Leghorn Branca com 14 meses de idade, alojadas a duas por gaiola; o delineamento experimental foi inteiramente casualizado, sendo três tratamentos com quatro repetições, constituindo 20 aves cada parcela. A determinação diária da cor foi feita em gemas de dez ovos de cada parcela, nos períodos pré-experimental (10 dias), experimental (20 dias) e pós-experimental (até que a coloração retornasse ao normal). A avaliação subjetiva da cor foi feita pelo leque colorido da Roche, dando os resultados por uma escala de 1 a 15 pontos, e a objetiva, pelo colorímetro diferencial Hunter, que expressa os resultados através de três parâmetros. Os resultados mostraram que o efeito dos corantes apareceu a partir do quinto dia do inicio da sua adição e permaneceu por seis a sete dias após sua suspensão; houve diferença significativa ao nível de significância de 1% entre a testemunha e os dois tratamentos com corantes, não ocorrendo, entretanto, diferença significativa entre estes. Os métodos utilizados para determinação da cor em gemas do ovos estão altamente correlacionados.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBarriga, Firton AcháGava, Altanir J.Andrade, Alfredo N. deÁvila, LuísDias, Paulo Genaro de O.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17068Pesquisa Agropecuaria Brasileira; v.10, n.4, 1975: Série Zootecnia; 13-17Pesquisa Agropecuária Brasileira; v.10, n.4, 1975: Série Zootecnia; 13-171678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17068/11391info:eu-repo/semantics/openAccess2014-04-15T19:01:47Zoai:ojs.seer.sct.embrapa.br:article/17068Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:01:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
