Processamento, caracterização físico-química e digestibilidade da silagem biológica de resíduos de tambaqui na alimentação de poedeiras comerciais

Abstract

The objective of this study was to evaluate the potential for production of silage from the waste from the processing of the tambaqui, evaluating the chemical and nutritional characteristics and the same use in the diet of laying hens for light commercial verification of apparent digestibility and energy metabolism. Treatments for production of silage if differentiated as the amount of inoculum (pure cultures of Lactobacillus plantarum). In the digestibility assay were used 72 layers of White Hisex with 62 weeks of age. For the treatments are designed to control feed and the feed with inclusion of 5% of the residual biological silage tambaqui. The biological method for preparation of silage from the residue of tambaqui obtained positive results in the conservation of the residual mass in clamped all percentages of inoculum. During the evaluation of the centesimal composition of organic wet silage tambaqui residue, the treatments were no significant difference and remained close in relation to residue in natura. In the dehydration of the product held with 14 days of inoculation, the centesimal composition of the product in their treatments presented promising results. Treatment with 2,5% of inoculum excelled the other treatments with regard to nutritional parameters for use in feed of layers, showing concentration of crude protein (CP)-33,29%, lipídieo (L)-33,65% and minerals Ca-21,26 g/Kg-¹ and P-11,98 g/ Kg-¹. The dehydrated product with 35 days of inoculation also presented excellent results for analysis of centesimal composition. The inclusion of 5% biological silage of tambaqui on light commercial layer diet showed good performance in the metabolism of protein and lipid, can be considered as a protein food or energy for use in power layers. The preparation of organic fish silage becomes an alternative to the fishing industry, promoting a sustainable and profitable destination, waste generated during processing, with potential for use in animal feed.
