ENSILADO DE RESIDUOS DE MANGO (MANGIFERA INDICA L.) PARA LA ALIMENTACION ANIMAL CARACTERISTICAS FERMENTATIVAS
Several factors which may be involved in changes of fermentative characteristics of ensiled mango residues were evaluated. A 2 x 6 x6 factorial arrangement was used to study the influence of harvesting season, June and August, time of conservation, 0, 7, 14, 21, 42 and 84 days, as well as six differ...

| Sumario: | Several factors which may be involved in changes of fermentative characteristics of ensiled mango residues were evaluated. A 2 x 6 x6 factorial arrangement was used to study the influence of harvesting season, June and August, time of conservation, 0, 7, 14, 21, 42 and 84 days, as well as six different types of silage, three prepared with ripe fruits discarded for human consumption, and three made with the industrial residue of mangoes, mainly composed of peels and seeds. All silage contained maize stover (10 and 20%) with the addition or not of sugar cane molasses and urea. There were significant (P<0.05) differences for season x additive, season x days of conservation, additive x days of conservation and season x additive x days of conservation interactions, either in pH of samples or in total acidity and SCFA content. Ammonia concentration was only affected by a significant (P<0.05) season x additive interaction. Overall, silages appeared as stable materials between 14 and 21 days from the point of view of pH and total acidity. Ensiling in August showed to account for better fermentative parameters as compared to those prepared in June. Silages containing urea had a higher concentration of ammonia. It is suggested that it is possible to use silage prepared with either discarded ripe mangoes or industrial residues for animal feeding, otherwise containing 10 or 20% maize stover to what urea and sugar cane molasses must be added at levels of 2 and 3%, fresh basis. It is considered that studies should be carried out to add materials which determine pH values lower than 4.2 if urea is included in the silage. These silages must be evaluated in performance trials with animals. |
