To enhance the bioproductive effect of the essential oil mixture 0.05%, we associated to this an acidifying mixture consisted of calcium propionate and calcium formate 0.03% in the experimental variant (V2); in the third experimental variant, beside the same essential oil doses and acidifying substances, we added 0.45% of a probiotic Bacillus subtilis and Bacillus licheniformis-based preparation. Compared with the reference variant (V1), the association of essential oils with acidifying substances (V2) does not influence the feed ingestion, but we may obtain a significantly bigger body weight (p<0.05), with 8.86%, and the reduction of the specific intake with 6.60%. In the variant V3, where the essential oils were associated with acidifying substances and probiotics, the feed intake has not been obviously changed, but the body weight grew significantly bigger (p<0.05), with 9.97%, and the specific intake got reduced with 6.1% compared with V1. The cholesterol level was not influenced by phyto-additives and neither by the association with acidifying substances and probiotics. The triglycerides got significantly reduced (p<0.05), with 44.45%, successive to the addition of acidifying substances to essential oils, and with 41.53% in the case of addition of acidifying substances and probiotics to the essential oils, compared with the reference variant.
