Previous researches proved the effects exerted by a mixture of mint (Mentha Piperita), savory (Thymus vulgaris) and sage (Salvia officinalis) essential oils on broiler health, due to their antibacterial, antifungal and antiviral action, and also the stimulation of the digestive secretions. 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.
