CONTINO-ESQUIJEROSA, Yuván et al. Evaluation of the productive performance in growing pigs fed a non-conventional diet. Pastos y Forrajes [online]. 2017, vol.40, n.2, pp.152-157. ISSN 0864-0394.

The objective of the research was to evaluate the productive and health performance in fattening pigs, fed a non-conventional diet. Twenty-four female and castrated male pigs were used, with average initial live weight of 23,96 kg and 11 weeks of age, randomly distributed at a rate of 12 animals in two treatments: A) conventional diet, based on commercial concentrate feed; and B) creole diet, elaborated with soybean and mulberry meal as protein sources, and sorghum and cassava meal as protein sources. The pigs were weighed at the beginning of the evaluation and every 14 days. The feed intake (kg day^-1), daily weight gain (kg day^-1) and feed conversion (kg DMkg^-1 LW), as well as some hematological indicators, were determined. There were no significant differences regarding live weight at 75 days of age (23,33 and 24,58 kg) and at slaughter (96,91 and 96,64 kg). The mean daily gain was 0,667 and 0,654 kg day^-1 for the control and the experimental treatment, respectively, with only a numerical difference of 13 g. The hematological indicators (hemoglobin and hematocrit) did not differ between treatments either. It is concluded that the use of a non-conventional concentrate feed elaborated from sorghum, cassava, soybean and mulberry meals did not affect pig production and allowed to save 2 244,4 kg of corn and 237,4 kg of soybean, for which its use is recommended to feed fattening pigs.
