Abstract : The aim of this study was to assess the influence of various diet processing methods and physical forms on digestibility and zootechnical performance parameters of nursery piglets. The study was performed in 2 phases. The first phase was performed twice with 120 piglets per experiment, for a total of 240 newly weaned piglets, in a randomized block design with 6 treatments and 5 replicates (30 pens). The following experimental diets were offered from weaning to 21 days after weaning (initial nursery phase) and included the following: mash diet (M); mash diet conditioned at 60ºC (CM); diet pelleted at 60ºC/matrix 2.5 mm (P2.5); diet pelleted at 60ºC/matrix 2.5 mm and crumbled (P2.5C); diet pelleted at 60ºC/matrix 4.75 mm (P4.75); and diet pelleted at 60ºC/matrix 4.75 mm and crumbled (P4.75C). The animals? daily weight gain (DWG), daily feed intake (DFI) and feed conversion (FC) were assessed. Phase 2 used 24 piglets (33 days old) from Phase 1, which were lodged in individual metabolic cages. The experiment employed a randomized block design with 4 treatments and 6 replicates: mash diet (M); mash diet conditioned at 60ºC (CM); diet pelleted at 60ºC/matrix 2.5 mm (P2.5); and diet pelleted at 60ºC/matrix 4.75 mm (P4.75). Feces were collected to analyze the digestibility of and apparent digestible energy in dry matter, gross energy and ether extract. The processing and physical form of the diets did not affect the DWG and DFI of the 21- to 39-day-old piglets. The 2.5-mm-diameter pellets induced better FC compared to the crumbled and conditioned crumbled diets (P<0,05) which might be attributed to the better digestibility of the ether extract in the pelleted diets. Pellet size had no effect on the performance parameters. Resumo: O objetivo deste trabalho foi avaliar a influência de diferentes tipos de processamento e forma física da ração sobre a digestibilidade e parâmetros de desempenho zootécnico de leitões na fase de creche. O estudo foi conduzido em duas etapas. A primeira etapa foi repetida no tempo, com 120 leitões em cada experimento, totalizando 240 leitões recém-desmamados, num delineamento experimental em blocos ao acaso, com seis tratamentos e cinco repetições (30 baias). As dietas experimentais foram ofertadas do desmame aos 21 dias pós-desmame (fase inicial de creche), sendo: dieta farelada (F); dieta condicionada 60°C (FC); dieta peletizada 60°C / matriz 2,5 mm (P2.5); dieta peletizada 60°C / matriz 2,5 mm e triturada (P2.5T); dieta peletizada 60°C / matriz 4,75 mm (P4.75); dieta peletizada 60°C / matriz 4,75 mm e triturada (P4.75T). Foi determinado o ganho de peso diário (GPD), o consumo de ração diário (CRD) e a conversão alimentar (CA). Na segunda etapa foram utilizados 24 animais (33 dias de idade), provenientes da primeira etapa, os quais foram alojados individualmente em gaiolas metabólicas. O delineamento experimental foi inteiramente ao acaso, com quatro tratamentos de seis repetições cada: dieta farelada (F); dieta condicionada 60°C (FC); dieta peletizada 60°C / matriz 2,5 mm (P2.5); dieta peletizada 60°C / matriz 4,75 mm (P4.75). Foram realizadas coletas de fezes para determinação da digestibilidade da matéria seca, energia digestível aparente na matéria seca, energia bruta e extrato etéreo. O processamento e a forma física da ração não afetaram o GPD e CRD dos leitões dos 21 aos 39 dias de idade. A peletização a 2,5 mm de diâmetro proporcionou melhor CA em comparação às rações farelada e farelada condicionada (P<0,05), o que pode ser atribuído a maior digestibilidade do extrato etéreo nas dietas peletizadas. O tamanho do pelete não teve efeito sobre os parâmetros de desempenho.

Abstract: We tested the efficacy of a commercial product (Glucan-MOS®) derived from yeast Saccharomyces cerevisiae, containing two combined products, Beta-1,3-1,6 glucans and mannans on the growth, feed efficiency, stress and innate immune responses of juvenile pacu (Piaractus mesopotamicus) after a stressful handling and bacterial inoculation. For this, we evaluated the serum cortisol and plasma glucose levels, the respiratory activity of leukocytes, the serum lysozyme levels, as well as the number of circulating erythrocytes and leukocytes of fish fed during 30 days with diets containing increased levels of Glucan-MOS (0.0, 0.1, 0.2, 0.4 and 0.8%). The supplementation of 0.1% improved weight gain, feed conversion and the protein efficiency ratio compared to a control diet. The 0.2 and 0.4% Glucan-MOS® diets were sufficient to increase the respiratory burst of leukocytes and lysozyme activity, the number of thrombocytes, neutrophils and monocytes in the blood after a stressful handling and bacterial challenge, and minimized stress response as shown by decreased cortisol and glucose levels when compared to the control. The results of this work reinforce the benefits of the adoption of feeding strategies including combination of both Beta-1,3-1,6 glucans and mannans as a dietary supplement in periods prior to intensive management. The 30-day period was sufficient to stimulate growth performance, improve nutrient utilization, minimize stress response and modulate innate immunity responses.
