Pineapple bran (more aptly described as pulp) consists of the skin and often the core of the pineapple, and accounts for an estimated 40–50 percent of the total pineapple weight. Because of its rather high fibre content, the bran is more suitable for ruminants than for monogastric animals. The net energy values of pineapple bran and pineapple hay are reported to be 118.8 and 85.8 Mcal/100 kg (Otogaki et al., 1961). Fresh pineapple bran usually contains only about 10 percent dry matter, and because of this it is more convenient to feed it in the vicinity of the factory during the canning season. Long-distance transport is both difficult and expensive. However, if pineapple bran is needed elsewhere for feeding, it is possible to employ such techniques as drying (either in the sun or using a conventional dryer) and conserving as silage, in which case the fresh bran is mixed with other ingredients with higher dry-matter content.
O'Donovan, Chen and Lee (1972) investigated a number of pineapple bran silage mixtures (Table 2). Those incorporating molasses or molasses and a source of starch (maize and sweet potatoes) fermented satisfactorily, and it was possible to formulate a wide variety of suitable mixtures, bearing in mind the importance of silage-making and fermentation principles. Partial or complete sun drying is possible, but it is hazardous during the rainy season.
