Efeitos da peletização e extrusão sobre a digestibilidade de ingredientes alternativos do Semi-árido Nordestino para a tilápia do Nilo

Abstract: ResumoFoi avaliada a digestibilidade aparente dos nutrientes e energia da raspa de mandioca (RM), a farinha de resíduo de abate de caprinos/ovinos (FR) e a farinha de feno de maniçoba (FM), para a tilápia do Nilo em rações processadas na forma peletizada e na forma extrusada. Os coeficientes de digestibilidade aparente da proteína e energia brutas para a RM, o FR e a FM em rações peletizadas foram respectivamente 77,97 e 65,86%, 93,79 e 88,62%, 54,62 e 28,64%. Os coeficientes de digestibilidade aparente da pro… Show more

“…The pelleting of M. esculenta from scraps of the same plant, in comparison with extrusion, was SSS for gross energy digestibility, SSI for dry matter digestibility, and no SSD for crude protein. The extrusion of M. glaziovii hay behaved in the same way, but in terms of gross energy and crude protein digestibility, it did not show SSD with respect to the pelleting [136].…”

“…In this study, protein hydrolysates and slaughter residues from poultry and swine were used, and ADC values in dry matter, protein, and energy SSS were reported in some of the diets [140], showing a beneficial effect of the hydrolysis process for the development of fish feed. Another study evaluated slaughter residue meal from goat and sheep and reported no SSD in ADC values in pelleted diets and SSI in ADC protein in diets processed by extrusion [136]. This study and the one conducted with dry protein hydrolysate from tilapia fillet waste [129] did not perform a digestibility analysis with respect to a control diet.…”

“…Uma das formas de processamento dos alimentos é a extrusão, que gera um alimento com capacidade de flutuação e coesão na água (Melo e Stipp, 2011). Na extrusão, a temperatura do processamento pode chegar a mais de 150 ºC, alterando a estrutura dos ingredientes e aumentando a digestibilidade aparente da energia e da proteína (Santos et al, 2014). Na peletização, os ingredientes são compactados mecanicamente sem Vales do São Francisco e Parnaíba (CODEVASF) in Três Marias/MG, during 21 days.…”
