LY, J. et al. In vitro digestibility of products from coconut (Cocos nucifera L.) endosperm for fattening pigs. Technical note. Cuban J. Agric. Sci. [online]. 2017, vol.51, n.4, pp. 471-476. ISSN 2079-3480.

In vitro digestibility (pepsin/pancreatin) of dry matter, organic matter and nitrogen was studied in 15 samples of endosperm of coconut (Cocos nucifera L.), defatted or not, grated in natura, from Artemisa, Mayabeque and Havana, provinces from the West of Cuba. A completely randomized design was applied, in a 2 x 3 factorial arrangement with five repetitions. With defatting, a significant decrease or increase (P <0.05) in the concentration of organic matter or nitrogen was determined, without effect of the place of origin. Nitrogen content of the endosperm without defatting or defatted was 1.01 and 3.40 % on dry basis, respectively. There was no significant effect (P> 0.05) of defatting nor of the origin of the stocking in in vitro digestibility of dry matter, organic matter and nitrogen, with values of 48.7, 44.5 and 57.7 %, respectively. It is suggested that supplying endosperm of coconut tree, milled and in natura to pigs may be considerably useful as an energy and protein source, due to its ileal digestibility.
