The aim of this trial was to evaluate the effect of prenatal and postnatal inclusion of a combination of essential oils (EO) on performance parameters and diarrheas after 2 weeks post-weaning. The trial followed a 2x3 factorial design; 2 sow diets: basal or with EO at 375 g/t x 3 piglet diets: basal diet, medicated with 200 ppm of colistin or treated with 375 g/t of EO. A total of 168 weaned piglets were randomly distributed in the 6 groups: 3 from basal sows (CC, CA and CT) and 3 from EO sows (TC, TA and TT), being the animals from the TT treatment the ones imprinted. The incidence of diarrhea was recorded twice a day and calculated using the percentage of animals with diarrhea over the total period of observations carried out. The animals were weighed at 14 days post-weaning. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were calculated. Data were analyzed by two-way ANOVA using GLM procedure of SAS. Animals from the TT group had significantly lower incidence of diarrheas from 0 to 14 days post weaning. Diarrhea was recorded on 4.7b% of the observations (TT group), being significantly lower (P ≤ 0.001) than the animals from CC (10.8a%), CA (13.7a%), CT (10.7a%), TC (14.4a%) and TA (12.9a%). Performance parameters indicated that there were non-significant differences in BW, ADFI, ADG with numerically lower FCR (kg/kg) 1.14 in TT group (CC 1.23, CA 1.33, CT 1.27, TC 1.22, TA 1.23). Despite the non-significant differences in performance parameters, in this study the effect of imprinting with essential oils reduced diarrhea incidence. |
