Abstract

The objective of this study was to determine the potential use of pineapple by-products in the diet of ruminants. A compilation of data and subsequent statistical analysis was performed on globally published research up until 2013. The results were used to create a nutritional characterization of the pineapple organ by organ, including whole plant, stover (leaves, stem and ratoons), fruit crown, heart, skin and fruit pulp, stem and roots. This characterization aims to optimize its use in ruminant feeding. Analysis of data was also performed to characterize by products for silage, including dried or fresh material without additives. The nutritional composition of the materials was different according to the portion of the plant analyzed. The roots had the highest dry matter, the most neutral detergent fiber, the most acidic detergent fiber, and the highest lignin and ash content. In contrast crowns and stover had the highest content of crude protein and energy, but the lowest dry matter content. There is a difference between dried materials, fresh materials and materials for silage, but high moisture materials showed no significant differences. It can be concluded that products obtained from pineapple production systems, haveenough energy and nutrient content to allow their use as part of the total daily ration in ruminant feeding, without having noticeable adverse effects on productive performance.
