Effect of Microbial Additive on Productive Performances, Meat Quality and Intestinal Microbiome of Quails

The paper presents the experimental results on the influence of a CMP-3 microbial additive, derived from yeast and spirulina extracts, on the growth and development of quails. The experiment was conducted on 200 Phoenix breed quails (1 day old), divided into two groups: the control group (CG) and the experimental group (EG). Quails from CG, during the period of 1-60 days, consumed basic combined feed (BCF), and those of EG, during the period of 1-44 days, consumed the BCF supplemented with 0.5% CMP-3 additive, and during the period of 45-60 days, the BCF supplemented with 0.25% additive. It was established that the inclusion of the CMP-3 additive in the daily ration of quails ensures at the end of the experiment the viability of chicks in the EG of 98% compared to 83% in the CG, statistically significantly increases (P˂0.001) the body mass and pectoralis muscle of quails in the EG by 12.03 and 11.95% respectively compared to the CG, reduces the specific feed consumption by 5.53% and stimulates the beneficial intestinal microbiota of the chicks. The use of the additive allows a significant increase (P˂0.05) in the protein and water content of poultry meat by 3.9% and 3.7%, respectively, while simultaneously reducing (P˂0.001) the lipid content of the meat. The microbial additive has potential for practical use in maintaining the chick population, stimulating productive performance, and improving the quality of quail meat.
