PICOT, J.A. et al. Modificación de variables productivas por inclusión del "poroto caupí" (Vigna unguiculata) en la alimentación de cerdos. Rev. vet. [online]. 2015, vol.26, n.1, pp.49-53. ISSN 1669-6840.

It is recommended that for animal feeding the ingredients in the diet should be obtained in the same region of the exploitation. In northeastern Argentina it is possible to use "cowpea beans" (Vigna unguiculata) as a protein resource. The objective of this trial was to verify the suitability of "cowpea beans" to replace expeller soybean in different proportions in the diet of growing pigs, measuring parameters of productive performance. For the trial a totally randomized blocks design was used. It lasted 30 days: 9 days for adaptation and 21 days for measurements. The experience included 12 animals and 3 diets; T1: basal diet (BD) made with ground corn (66%) and soybean expeller (29%), T2 and T3: BD to which 50% and 75% of soybean expeller were replaced by "cowpea beans", respectively. Statistical analysis was performed with the InfoStat software. The analysis showed that among T1, T2 and T3 treatments there were not significant differences (p>0.05) for the daily weight gain (0.25; 0.25 and 0.28 kg/day respectively), daily food intake (1.06; 0.99 and 1.00 kg DM/day) neither nutritious conversion (4.21; 3.44 and 4.64 kg). This allows us to conclude that the use of "cowpea beans" at different levels of substitution of soybean expeller is a viable option for growing pigs
