Exigências de cálcio e de fósforo disponível para codornas japonesas de 26 a 38 semanas de idade

Abstract: Este experimento foi conduzido com objetivo de avaliar niveis de cálcio e fósforo disponível para codornas japonesas. Foram utilizadas 12 dietas e sete repetições de oito aves por repetição num total de 672 aves, as quais foram distribuídas segundo um delineamento inteiramente casualizado, em esquema fatorial, com três níveis de cálcio (2,0; 2,5 e 3,0%) e quatro de fósforo disponível (0,10; 0,17; 0,24 e 0,31%). Observou-se interação significativa entre os níveis de cálcio e fósforo disponível para o consumo de… Show more

“…Therefore, the evaluated levels and interactions between these minerals may have influenced the experimental results. Phosphorus metabolism is directly related to dietary Ca levels, and it influences bone eggshell Ca deposition in laying Japanese quails and chickens (Costa et al, 2007;Almeida et al, 2009;Vieira et al, 2012).…”

“…Currently, Ca and avP requirements for Japanese quails can be obtained from published nutritional tables (NRC, 1994;Rostagno et al, 2011) as well as from published studies (Costa et al, 2007;Vieira The Effect of Calcium and Available Phosphorus Levels on Performance, Egg Quality and Bone Characteristics of Japanese Quails at End of the Egg-Production Phase et al, 2012;Aguda et al, 2013). However, these requirements were obtained in studies evaluating quails at the beginning of the egg-production phase and during the peak of egg production (Costa et al 2011).…”

“…However, the relative weight of quail eggs is higher, and may reach 10% of body weight. The weight of eggs of quails has a mean value of 12 g [17][18][19][20] and eggs of laying hens around 65 g [21][22][23][24].…”

“…Apesar das três marcas de rações apresentarem grande parte dos valores divulgados dos níveis de garantia similares aos avaliados, atualmente sabe-se através de inúmeros trabalhos na área (Vieira et al, 2012;Nery et al, 2013), que estes níveis podem ser alterados, a fim de, proporcionar uma melhor relação custo/benefício, maximizando a produção e diminuindo o custo da atividade.…”
