ALVARADO ALVAREZ, Hugo Javier et al. Saccharum officinarum L. in Swine´s Diet. Rev. prod. anim. [online]. 2018, vol.30, n.1, pp. 8-12. ISSN 2224-7920.

In order to integrate alternative plant sources of energy in the diet of swine weaned in the stages of growth and finishing, twenty, Landrace x Yorkshire castrated animals were used. Their diets were based on 15 and 13 % gross protein. Chopped stems of fresh sugar cane without peeling, were included in the diet, at 15; 20, and 25 % (growth); and 25; 30, and 35 % (finishing). The trial lasted 14 weeks. A completely randomized design was used with four treatments and five replicas; the Duncan´s significance test (5 % probability) was also performed. The inclusion of 30 % of sugar cane stems produced the highest mean weight values (83.80 kg, P < 0.05). The highest weight gain value was observed in the pigs that consumed inclusion diets of 20 % sugar cane, whereas the best values for the finishing stage was the 30 % inclusion variant. The inclusion of 35 % in the finishing stage had the best feed conversion (2.19 kg/kg, P < 0.05). The addition of 20-30 % of chopped sugar cane stems was recommended to fatten pigs.
