The objective of the current project was to evaluate Natural Effective Microorganisms (NEM) as growth promoters, for which 100 one-day-old broiler chickens were used, randomly distributed in two groups. The research lasted 40 days, and the treatments were distributed as follows: control group (CG) balanced + water and treatment group (TG) balanced + 0.5 ml NEM/l of water. The parameters weight, weight gain, mortality, length and width of intestinal villi, depth of intestinal crypts, and benefit-cost were evaluated. The inclusion of NEM in the diet of the broilers presented in the TG an increase in the obtained values on the length of the villi and the depth of the intestinal crypts, which, according to the statistical "T-student" test, valued <0.05, indicating a significant difference between groups. Concerning the productive parameters, the results were p>0.05, indicating no significant difference between both study groups. Finally, in the benefits-cost variable, the difference favored the CG, with a gain of 0.03 cents concerning the TG. This indicates that applying NEM would favor the absorption of nutrients and protection against pathogens since it increases the length and depth of the intestinal crypts, protecting against pathogens. |
