Different calcium sources on the productive performance and bone quality of meat quail/Diferentes fontes de calcio sob o desempenho produtivo e qualidade ossea de codornas de corte

Zusammenfassung:This study was developed to examine the effect of using charru mussel-, magunim- and oyster-shell meals as calcium sources on the productive performance, carcass yield and bone parameters of meat quail. A total of 250 one-day-old non-sexed European quail were used. The birds were distributed into five treatments (calcium sources: calcific lime, calcium carbonate, charru mussel shell meal, magunim shell meal or oyster shell meal) in a completely randomized design with five replicates and ten birds per experimental unit. Feed intake, weight gain and feed conversion were evaluated from one to 35 days. At 35 days, two birds with the average weight of the plot were slaughtered per plot and used for analysis of carcass yield and bone parameters. There were no significant differences (P > 0.05) in feed intake, weight gain, feed conversion, carcass yield or tibia dry matter content, ash content and strength. The charru mussel-, magunim- and oyster-shell meals can be used as calcium sources in the diet of European quail without affecting their productive performance, carcass yield or bone mineralization. Key words: european quail, mollusk shells, organic calcium sources. Objetivou-se avahar o efeito da utilizagao das farinhas de conchas de sururu, magunim e ostra como fontes de calcio sobre o desempenho produtivo, rendimento de carcaga e parametros osseos de codornas de corte. Foram utilizadas 250 codornas europeias, nao sexadas, com um dia de idade. As aves foram distribuidas em delineamento inteiramente casualizado, constituido por cinco fontes de calcio (calcario calcifico, carbonato de calcio, farinha de conchas de sururu, farinha de conchas de magunim efarinha de conchas de ostras), com cinco repetigoes e dez aves por unidade experimental. Foram avahados o consumo de ragao, ganho de peso e conversao alimentar no periodo de um a 35 dias. Aos 35 dias, duas aves de peso medio de cada parcela foram abatidas e utilizadas para as analises de rendimento de carcaga e parametros osseos. Nao foram observadas diferengas significativas (P > 0,05) para os dados de consumo de ragao, ganho de peso, conversao alimentar, rendimento de carcaga, materia seca, cinzas e resistencia ossea de tibias. As farinhas de conchas de sururu, magunim e ostra podem ser utilizadas na alimentagao de codornas europeias, como fontes de calcio, sem afetar o desempenho produtivo, rendimento de carcaga e a mineralizagao ossea das aves.
