Abstract
The purpose of this study consisted in evaluating the productive performance and the total digestibility of pigs fed with Lemna gibba at different levels of inclusion (0, 10%). In the first trial, twenty castrated hybrid males were used from an average of 23 to 66` kg of BW in a completely randomized design with 2 treatments and 10 repetitions; for the second trial, there were 8 animals (4 repetitions per treatment). The control diet consisted of a mixture of sorghum, soyameal and a vitamin and mineral premix, whereas the experimental diet contained 10% lemna collected from the Xochimilco region and sun-dried thereafter. Nutrient content of lemna was in per cent in dry basis, 27.82 crude protein, 1.10 ether extract, 24.15 ash, 11.07 crude fibre, 47.84 NDF, 35.02 ADF, 8.48 lignin, 8.31 silica, respectively. Results were statistically analyzed through a t-Student test with a significance level of P0.05. There were no significant differences between treatments for live weight gain (730 and 770 g/day respectively), feed conversion (2.93 and 2.96 kg DM intake/kg gain respectively and final weight (66.43 and 69.81 kg respectively). Significant differences (P0.05) were only found in the digestibility trial for dry matter digestibility (84.30 and 81.31% respectively) and protein digestibility (71.68 and 67.26% respectively). It was concluded that 10% of Lemna gibba inclusion in a pig ration can be used under practical conditions.
