Blend de aditivos para melhor aproveitamento nutricional em dietas de codornas japonesas (coturnix coturnix japonica) em postura

Abstract

The objective was to evaluate the effect of replacing meat and bone meal with an additive based on enzymes and organic acids in diets of Japanese quails in production. 144 quails aged 32 weeks were used, distributed in a completely randomized design, in three treatments and six replications, with eight birds per experimental unit. The treatments were: without use of meat and bone meal, without dicalcium phosphate and with 1% of the additive (1AD), without additive, without dicatcium phosphate and with free use for meat and bone meal (FCO) and without additive, without meat and bone meal, with free use of dicaicium phosphate (FB). The experiment was divided into five cycles of 21 days. Zootechnical performance, egg quality bone quality, blood parameiers, duodenum and jejunum histomorphomety, as well as liver glycogen reserve were evaluated. The results were submitled to ANOVA using the SAS OnDemand program and the means were compared using the Tukey test at 5%probability. The 1AD treatrent showed greater results for Haugh Unit (HU), Yolk Coloration (CG), Bone Resistance (RO), duodenum and jejunum absorptive area, hepatic glycogen concentration and ireproved Food Conversion per Feg Mass (CAM'O). Feed Conversion per Dozen Eggs(CADZ) It can be concluded that in the diet of Japanese quais, meat and bone meal and dicalciun phosphate can be replaced by the addinion of a biend of enzymes and organic acids in the proportion of 1,0 kg/ton of feed without causing damage to quality and performance of birds.
