The trial was conducted on zebu-type cattle (Bos indicus) under humid tropical conditions. Meat production and basic meat quality were assessed for 810 zebu bulls, aged 18-22 months and weighing 430 to 490 kg. Bulls were randomly assigned into one of three groups: ZHg, treated with the generic ZH (Zipamix®) preparation; ZHr, treated with the reference ZH (Zilmax®) preparation, and Cg, the untreated control group. Housing, shade surface, feeding and water availability were highly homogeneous between the animals’ pens. Results for the measured productive and meat quality parameters showed that both ZH-treated groups had higher values than the Cg (P < 0.05), and differences between the ZHg and ZHr groups were not statistically significant, thus fulfilling the criteria of a non-inferior ZH preparation. In this assay, ZH supplementation did not modify the amounts of moisture, fat, protein or ash in the Longissimus dorsi muscle compared with the meat from non-supplemented animals, and the overall meat acceptability was unaffected (P > 0.05). 2018 artículo científico 0301-5092 https://www.redalyc.org/articulo.oa?id=42371696002 https://www.redalyc.org/journal/423/42371696002/ https://www.redalyc.org/journal/423/42371696002/html/ https://www.redalyc.org/journal/423/42371696002/42371696002.epub https://www.redalyc.org/journal/423/42371696002/movil 10.21753/vmoa.5.2.482 en http://www.redalyc.org/revista.oa?id=423 Veterinaria México application/pdf Universidad Nacional Autónoma de México Veterinaria México (México) Num.2 Vol.5 |
