González Ana J. Rondón M. L. Pérez A. Beruvides Irani Placeres Estudios Agrarios Probiotics heavy birds endospores of Bacillus subtilis In order to evaluate the zootechnical additive SUBTILPROBIO® E-44 in productive and health indicators in E1 heavy pure breeds birds under production conditions, an experiment for a period of six weeks was developed. A completely randomized design was applied, with two treatments: control group corn-soybean basal diet and group I basal diet + SUBTILPROBIO® E-44 zootechnical additive. A total of 1800 birds with an average weight of 43 g were used, distributed in 900 birds per treatment. They were located on the floor, in similar conditions of management and feeding. To determine the probiotic effect of this zootechnical additive, live weight, conversion, uniformity, viability and mortality were evaluated. The results showed that the birds from the fourth week to the sixth expressed a probiotic response in the productive indicator live weight (4:1472g/1406), (5:1897g/1826g) and (6:2387g/2336g) for P <0.01. At the end of the experiment, the productive indicators live weight (2387g/ 326g) and conversion showed significant values (1.8/1.9) for P <0.01, as well as uniformity (88/84 %) for P <0.001, with respect to the control group and to the standard for the breed under study. The mortality (3.8/8) and viability (96.2/92 %) indicators showed differences with respect to the control for P <0.01. The results of the research show the feasibility of using this zootechnical additive as an improver of the productive and health indicators for this poultry category. 2021 artículo científico 0864-0408 https://www.redalyc.org/articulo.oa?id=653767641007 https://www.redalyc.org/journal/6537/653767641007/ https://www.redalyc.org/journal/6537/653767641007/html/ https://www.redalyc.org/journal/6537/653767641007/653767641007.epub https://www.redalyc.org/journal/6537/653767641007/movil en http://www.redalyc.org/revista.oa?id=6537 Cuban Journal of Agricultural Science application/pdf Instituto de Ciencia Animal Cuban Journal of Agricultural Science (Cuba) Num.1 Vol.55 |
