Abstract
GUTIERREZ, Francisco; GUACHAMIN, David and PORTILLA, Arnulfo. NUTRITION VALUATION OF THREE FEEDING ALTERNATIVES IN THE GROWING AND FATTENING OF PIGS (Sus scrofa domestica) NANEGAL-PICHINCHA. La Granja [online]. 2017, vol.26, n.2, pp.142-154. ISSN 1390-8596. https://doi.org/10.17163/lgr.n26.2017.12.
The pigs’ diet can be diverse, based on feed, kitchen waste, and crops´waste, which can be seen as an opportunity if known how to use this alternative feeding mechanism for this specie. In Ecuador various crops are produced and their waste can be used in pigs feeding, not as a unique source of nutrition but as a complementary diet. In this research done in Nanegal, in the North West of Pichincha, endemic crops were used such as banana (Musa × paradisiaca), white carrots (Arracacia xanthorrhiza), and sweet potato (Ipomoea batatas). An adaptation period is needed for the animals to be fed with crop’s waste and they can reach superior consumption levels compared to animals only nurtured with feed, weight gains superior to 0,9 kgs per day, nutrition conversions of 3,4 and performance to the canal of 78% and a dorsal fat density of 25mm.
Keywords : Nutrition; crops waste; banana; sweet potato; white carrot.
