Avaliação do carbo-amino-fosfoquelato como uma fonte de minerais na ração de poedeiras e codornas japonesas

Abstract

The objective was to evaluate the effect of mineral supplementation, organic and inorganic, in the feed of laying Japanese quails and on performance, bone strength, quality and shelf life of eggs. Two experiments were conducted, with 320 layers of Dekalb White lineage distributed in a completely randomized design with two treatments, ten replicates with 16 birds each; and another with 192 Japanese quails also distributed in a completely randomized design with two treatments, six replicates of 16 birds per experimental plot. The treatments consisted of a basal diet formulated to meet the requirements of the birds, supplemented with trace mineral premix in organic form (carbo-amino-phospho chelate) and inorganic (sulfate). The trace elements present in the premix were selenium, iron, manganese, copper and zinc. Statistical analysis of performance data, quality and bone strength were compared by Student's t-test at 5% probability and the nonparametric Kruskal Wallis, and shelf-life data was submitted to the T-Student test function of the mineral source, and function in regression of storage days. In the first experiment, the mineral springs influenced (p> 0.05) feed intake (CR, g), egg weight (PO, g) and mass of eggs (MO, g) of laying; all the quality variables of the eggs were influenced (p> 0.05), except the yolk weight (PG, g) and percentage of peel (PORC%) and the variables on the shelf life also was no influence (p > 0.05) of mineral and interaction between time and source of the mineral sources were observed. In the second experiment, with Japanese quails, there were no differences (p <0.05) in the performance of the birds, the egg quality variables, only Haugh unit (HU) and the shell thickness (EC, mm) were affected ( p> 0.05) and the shelf life variables were influenced (p> 0.05) by mineral sources. The organic source improves the performance and quality of laying eggs and Japanese quails, especially in the variables related to the shell and to maintain the internal and external egg quality in shelf life.
