Abstract

In the pig farm San José de Macají, located in the city of Riobamba, Chimborazo province at an altitude of 2800 m.a.s.l, a commercial alternative extract medicinal plants (carvacrol, cinnamaldehyde and capsaicin) was evaluated at 150 mg / kg food in the diet of pigs Topigs commercial line in the finishing stage, compared to a control treatment (0 mg / kg food). For this investigation 40 barrows in the fattening phase of 110 days old with an initial weight approximately 63 ± 3 kg, which were randomly divided into five repetitions with four experimental units per group were used. By comparison with the statistical t-student for independent samples it was determined that the best results in terms of final weight (125.70 kg), weight gain (62.80 kg) and feed conversion (3.42) corresponds to the use of 150 mg of microencapsulated / kg of food substance also worth noting that there was no presence of mortality. The highest rate of benefit / cost in the finishing stage was $ 1.25, ie a yield of 25% was obtained by adding a microencapsulated substance with medicinal plant natural extract (150 mg / kg food). Consequently it is suggested to include in the diet of pigs in the fattening stage microencapsulated 150 mg / kg of food substance, in the same driving conditions as the best productive and economic parameters were recorded.
