Poster16: Growth of pig fed with Vigna unguiculata herbage meal as protein supplement

  1. 1. Growth of pigs fed with Vigna unguiculata herbage meal as protein supplement P.Sarria1, L.F. Rivera1, R. Araujo1, S. Martens2and M. Peters2 1Universidad Nacional de Colombia, A.A. 237 Palmira, Colombia (pisarriab@palmira.unal.edu.co) 2 Centro Internacional de Agricultura Tropical (CIAT), A.A. 6713, Cali, Colombia 1. THE MESSAGE 4. RESULTS & DISCUSSION Vigna unguiculata herbage has the potential to contribute to • There were no significant differences between treatments for the the protein supplementation in the diet of fattening pigs, analyzed variables (see Table 2). thus replacing parts of commercial feed concentrates. • Although the feed conversion did not differ significantly, there was a lineal negative response with increasing cowpea level in the diet (R² = 0.6, P<0.001). That means that the nutrients of the control diet were better utilized by the animal for weight gain which shows a slight disadvantage of cowpea meal. Table2.

(Error bars show standard deviation) herbage meal maintaining the same theoretic crude protein and energetic level and similar fibre contents (Table 1). • The diet was distributed in 2 rations per day. Adaptation period was 7 days and the measuring period 49 days. 5. CONCLUSION • Daily live weight gain daily feed consumption and feed conversion gain, were determined. • An inclusion of 33 % cowpea herbage meal in the total diet, making Table 1: Feed composition of the three test diets up around 30 % of the total dietary protein, can give good growth results in the phase of 20-60 kg liveweight.
