Previous issue date: 2014-08-25 / Com o objetivo de avaliar o efeito dos n?veis de caldo de cana de a??car desidratado (CCD)
(0,0; 1,5; 3,0 e 4,5%) na ra??o de codornas europ?ias (Coturnix coturnix coturnix) sobre o
desempenho, caracter?stica de carca?a e ?ndices econ?micos aos 22 dias de idade, 192
codornas de corte, foram distribu?das em delineamento inteiramente casualizado com quatro
tratamentos e seis repeti??es de oito aves por unidade experimental. N?o houve diferen?a
significativa para o desempenho das codornas em nenhum dos per?odos avaliados. Houve
efeito quadr?tico dos n?veis de CCD sobre o peso da carca?a (y=173,71 + 4,2767x - 1,2644x?,
R? = 0,99), coxa mais sobre-coxa (y = 36,055 + 1,1263x - 0,2256x?, R? = 0,91) e gordura
abdominal (y = 3,3295 - 0,8903x + 0,19x2
, R? = 0,97) onde os n?veis ?timos estimados foram
1,69; 2,50 e 2,34%, respectivamente. Houve efeito linear decrescente dos n?veis de CCD
sobre o peso de peito com pele (y = 66,267 - 0,5653x, R? = 0,83) e sem pele (y = 60,286 -
0,7193x, R? = 0,58). Na an?lise econ?mica, pode-se observar maior lucro ao produtor com a
utiliza??o da ra??o convencional. Entretanto, entre os n?veis de inclus?o de caldo de cana
observa-se que o n?vel 1,5% de CCD obteve os melhores resultados na an?lise econ?mica,
obtendo apenas uma diferen?a de margem bruta relativa de 0,47% em rela??o ao
convencional. Recomenda-se 1,69 e 2,50 e 2,34% de CCD para maior peso de carca?a, peso
de coxa+sobrecoxa e menor porcentagem de gordura abdominal de codornas de corte,
respectivamente. / In order to evaluate the effect of levels of dehydrated cane juice sugar (DCJS) (0.0, 1.5, 3.0
and 4.5%) in the diet of European quail (Coturnix coturnix coturnix) on performance on
performance, carcass characteristics and economical at 22 days of age indices, 192 quails
cutting, were distributed in a completely randomized design with four treatments and six
replicates of eight birds each There was no significant difference to the performance of quail
in any of the periods. Quadratic effects of levels of DCJS on carcass weight (y = 173.71 +
4.2767x ? 1.2644x?, R? = 0.99), thigh-thigh more about (y = 36,055 + 1,1263x ? 0,2256x?, R?
= 0.91) and abdominal fat (y = 3,3295 - + 0.8903x 0,19x2, R ? = 0,97) where the optimum
levels were estimated 1,69; 2.50 and 2.34%, respectively. There was a linear effect
descending of DCJS levels on weight breast with skin (y = 66.267 ? 0.5653x, R? = 0.83) and
without skin (y = 60.286 ? 0.7193x, R? = 0.58). In economic analysis, one can observe higher
profit to the producer with the use of conventional feed. However, between the levels of
inclusion of sugar cane juice is observed that the level of 1.5% DCJS obtained the best results
in economic analysis, obtaining only a difference of relative gross margin of 0.47% compared
to conventional. It is recommended 1.69 and 2.50% DCJS for higher carcass, thigh +
drumstick weight and lower percentage of abdominal fat quails, respectively.
