Evaluación de la ganancia de peso en cerdos suplementados con bacillus cereus variedad toyoi en la fase de precebos

Resumen

Today, the use of anabolics and antibiotics in the pig industry should be reduced, since they generate residual effects and affect public health. The objective of this research was to evaluate weight gain, nutritional conversion, and its possible effect on the reduction of diarrhea and disease in 83 animals of the Landrace, Large White and Píetran animals. 24 animals constituted the control treatment and 59 animals the alternate treatment, since they were supplemented with Bacillus cereus variety 1 x109 CFU / g, a probiotic growth promoter. Control pigs only received commercial pre-initiation concentrate, and pigs with alternate treatment received the probiotic at the dose of 1 kg / Tn of pre-initiation commercial concentrate (weaning phase) until the start of the lifting phase. Weight gain weighings were performed on day 10, 20 and 30 of the experimental period taking into account the racial factor and sex of the piglets. The results showed a positive effect, with respect to the daily gain in average grams per pig, finding that the average weight gain with probiotics is 13,530 +/- 2.6878 and for the average without probiotics 9.469 +/- 2 , 8596. The weight-gram-day gain was 422.81gr for the group treated and 295.62 for the control, in 32 days. Generating an alternative for small producers, who report low weight gain in the physiological stage of the pigs evaluated
