At the facilities of El Verdal poultry farm, located 1.6 miles away from Cali in the road to Jamundi, Valle del Cauca department, one research was conducted using 20 crossbred Yorkshire x Landrace pigs with 22 kg average initial weight, which were 127 days until they reached an average final weight of 86.4 kg. They were distributed at random in three treatments with different number of replications (one for the control and two for the experimental). The treatments were as follows: Boiled hens + Energy supplement (T1), Raw hens + Energy supplement (T2)and Control or Commercial type feed according to phase (T ). The main aim of this experiment was to look for the biological and economical feasibility of using whole hens (plus supplement) comming from the normal daily mortality or discard, from a commercial poultry farm, as an alternative feeding source for growing finishing pigs. There were no statistical significant differences for daily weight gain, feed efficiency and feed consumption. There was a slight higher feed consumption (dry matter) for T3 (2.14 kg), followed for TI and T2 (2.13 kg). In relation to daily weight gain, T) had 515 g; TI' 507 g and T2, 497 g. The best feed efficiency was for T) (4.16), followed for TI (4.2) and for T2 (4.28). Related to the economical results, higher feeding costs were for T) ($ 52 167) and lower for TI and T2 ($ 42 167). Profits for fattening pig were better for TI ($ 15 415), followed for T2 ($ 14587) and for T3 ($ 8208).
