A study conducted in Cuba at the Indio Hatuey Pastures and Forages Experimental Station investigated the effectiveness of a non-standard diet for fattening pigs, replacing 50% of the commercial concentrate with a diet consisting of soybean meal, mulberry flour, sorghum flour, and cassava flour. The study involved 24 pigs, with no significant differences in live weight, daily gain, feed conversion, or hematological indicators between the control and experimental groups. However, the experimental diet allowed for a significant reduction in corn and soybean usage, which the researchers highlighted as a cost-effective approach in addressing the instability and high costs of concentrate raw materials.
