A total of 276 crossbred YLxD castrate male and female pigs in aequal proportion averaging 43.2 kg initial live weight were allotted at random into three treatments according to a block design, with two replications per treatment in every block. Treatments consisted of offering ad libitum either fresh milled, in natura cassava roots or sugar cane stalks or swill mixed with sugar cane molasses type B (1:1 in dry basis). The employed cassava roots were from a sweet variety (cultivar, Señorita) usually directed to human consumption. In all treatments a protein supplement was given daily as a commercial concentrate (crude protein, 22%) at a rate of one kg/animal. The animals were housed in 12 pens allocated in a commercial fattening house (23 animals per pen). Final live weight (kg), feed intake (kg DM/day), daily gain (kg/day) and feed conversion (kg/kg) were 92.5, 2.46, 0.54 and 4.52; 82.7, 2.26, 0.44 and 5.20; 86.6, 2.68, 0.49 and 5.48 for treatments formulated to contain cassava roots, sugar cane stalks and swill, respectively. Feed intake was significantly (P0..001) less with sugar cane and feed conversion was significantly (P0.01) best with cassava roots. According to the results herein attained, it is possible to fattening pigs with fresh, milled cassava roots as the main energy source in the diet. However, it is recommended that milled sugar cane stalks should only be given as a complement of the ration.
