RESUMO:

The indiscriminate use of antimicrobials, together with misuse, has determined a global crisis of resistance to a wide variety of active principles. Substances such as prebiotics, probiotics, organic acids and essential oils may be alternatives to the use of conventional antibiotics. The objective of the present study was to test substitution alternatives to conventional antibiotic therapy administered in feed in growth / finisher animals. The experiment used 1056 growth and finishing pigs from 65 to 190 days old housed in 2 sheds with 48 pens each. The animals were submitted to six treatments totaling 16 replicates, being: T1: feed without antibiotics; T2: feed with antibiotic; T3: feed with prebiotic; T4: feed with probiotic; T5: feed with essential oil; and T6: feed with organic acid. Blood and faeces samples were collected from 192 animals (2 animals per bay) every 40 days, for later laboratory analysis of immunoglobulins and microbiota. Individual weighings were performed at each feed change, to determine individual weight gain and average daily gain. During the experiment, data on clinical occurrences, mortality, cough and sneezing index, presence of diarrhea and supply and leftovers were collected. The refrigerator was evaluated for pneumonia and pleurisy index, gastric ulcer index and carcass typing. Preliminary results showed a mean weight gain of 107.06 ± 0.9 kg, mean daily gain of 856.49 ± 7.7g and average carcass weight of 92.4 ± 0.7kg, with no significant difference between the treatments (P> 0.05). For cough and sneeze index, there was also no significance among the groups tested (P> 0.05). In the financial analysis, injecting medications were used in each treatment, averaging R$ 1.98 per animal (P> 0.05), which presented one or more diseases. During the 125 days of experiment, 27 animals died due to different causes. The results presented so far indicate that reduction and / or withdrawal of antibiotics in the pig feed can be considered a future perspective for the production of growing and finishing pigs.
