Alga calcária na dieta de codornas japonesas (Coturnix coturnix japônica) em fase de recria

Abstract

The objective of this work was to evaluate the substitution of inorganic calcium sources (calicitic limestone) by organic (calcareous seaweed) in the diet of beans in the recreate phase. The present study was carried out in the coturniculture sector of the Federal University of Grande Dourados (FCA/UFGD), Dourados -MS. We used 300 Japanese cordons, distributed in a completely randomized experimental design, with 3 treatments (T1= control (0% inclusion), T2= 0.50% of the diet of inclusion of limestone alag1; T3= 0.50% inclusion of calcarese diet 2, both in relation to the substitution of the inclusion of limestone from the diet, 10 replicates with 10 beans were used in each. Performance, carcass yield and cuts and meat quality in the recreate phase and the impact of treatments on egg performance and quality in the initial laying phase were evaluated. The data were submitted to anova and the comparison of means made by the tukey test at 5%. There was no difference between calcium sources in the variables feed intake, average weight, daily weight gain, total weight gain, feed conversion and average weight (P>0.05). Regarding carcass yield, cuts and meat quality of the birds, significant statistical differences were observed (P<0.05), where the birds that were fed with the sources of calcareous algae presented higher absolute and relative weight of the thigh. Organ weight and performance in the initial laying phase showed no effect of treatments. It was verified that there was influence (p<0.05) of the different types of calcium sources in the diet in the diet of codornas in the recreate phase, for the colorimetric fan color, albumen height, yolk height, Haugh unit and yolk index (p<0.05). The substitution of 0.50% of the diet of inclusion of calcarese seaweed in place of limestone can be used in the diet of quaints in the regrowth phase, without impairing the performance, carcass and organ yield and quality of meat and eggs.
