SUMMARY:

The objective of this work was to evaluate the impact of substitution of antibiotics used in pig feed with alternative additives in nursery, growing and finishing pigs. The experiment initially used 1,091 weaned pigs divided into 38 pens with six treatments during nursery and in the growing and finishing stage, 850 animals remained. At weaning the animals were divided by sex (females and males), submitted to the vaccination protocol and weighed individually to achieve the homogeneous distribution among the 6 treatments, being T1: antibiotic free feed, T2: antibiotic feed, T3: prebiotic feed, T4: probiotic feed, T5: essential oil feed, T6: organic acid feed. There was no difference in conversion rate between treatments at the nursey (P = 0.1969) or in growing and finishing stage (P = 0.8225). There was also no difference in the average daily weight gain in nursey (P = 0.05) and in growing and finishing stage (P = 0.3404). The cost of injectable interventions did not differ between treatments or at the nursey (P = 0.9804) or in growing and finishing stage (P = 0.3102). The pneumonia index in all treatments was above 1.0, indicating a respiratory challenge. The substitution of prophylactic use of antibiotics in feed in pig production is possible and the use of alternatives has not provided benefits.
