Effect of herbal methionine on productive performance of broiler chicken
We evaluated the performance of herbal methionine as a potential substitute for synthetic methionine in fattening chickens. To measure the effectiveness of amino acids from the two aforementioned sources, we assessed three treatments: T0 (dl- methionine), T1 (50% dl-methionine + 50% herbal methionin...

description | We evaluated the performance of herbal methionine as a potential substitute for synthetic methionine in fattening chickens. To measure the effectiveness of amino acids from the two aforementioned sources, we assessed three treatments: T0 (dl- methionine), T1 (50% dl-methionine + 50% herbal methionine) and T2 (T2 herbal methionine). We used 192 Cobb-500 chickens, distributed in three treatments and four replications. Data were analyzed by means of a completely randomized design using Tukey’s Test and an overall risk level of0.05. The study had four variables: food consumption, body weight, feed conversion and the European efficiency index. Using InfoStat 2013, results showed that T0 had the highest weight value 2556.10 g (±50.70), with no significant difference between groups. According to the previous parameter, the highest food consumption value was T0 with 1257.43 g (±31.85), with no significant difference between groups. With respect to feed conversion, T2 had the highest numerical efficiency (1.63; ±0.03) when compared with T0 1.64 (±0.03) and T1 1.65 (±0.03), but statistical similarity (p>0.05). The European efficiency index yielded a higher value (371.04) when compared with the other treatments because there was no mortality in chickens treated with synthetic methionine T1 (365.07) and T2 (342.72). We concluded that herbal methionine can be used as a substitute for dl-methionine in partial or total form. |

Para medir la eficiencia de los aminoácidos provenientes de las dos fuentes citadas, se propuso tres tratamientos: T0 (dl-metionina), T1 (50% dl-metionina + 50% metionina herbal) y T2 (metionina herbal). Se utilizaron 192 aves de la línea Cobb 500, distribuidas en tres tratamientos y cuatro repeticiones. Los datos se avaluaron mediante un Diseño Completamente al Azar, aplicando el test de Tukey al 0,05. Las variables en estudio fueron: consumo de alimento, peso corporal, conversión alimenticia e índice de eficiencia europeo, procesadas mediante InfoStat 2013. Como resultado T0 reportó el peso más alto respecto a los demás tratamientos 2556,10 g (±50,70), sin encontrarse diferencia significativa (p>0,05); en concordancia con el parámetro anterior, el mayor consumo de alimento corresponde al T0 con 1257,43 g (±31,85), sin observarse diferencia significativa (p>0,05) en este parámetro; en cuanto a la conversión alimenticia, T2 fue más eficiente numéricamente (1,63; ±0,03) comparado con T0 1,64 (±0,03) y T1 1,65 (±0,03), pero estadísticamente iguales (p>0,05); en el índice de eficiencia europeo T0 reporta un valor superior (371,04) con respecto a los demás tratamientos, ya que no existió mortalidad en el grupo de animales que consumieron metionina sintética; T1 (365,07) y T2 (342,72). Se concluye que la metionina herbal puede sustituir a la dl-metionina en forma total o parcial.Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López2016-06-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtículo revisado por paresapplication/pdftext/htmlapplication/ziphttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/112Revista ESPAMCIENCIA; Vol. 7 Núm. 1 (2016): REVISTA ESPAMCIENCIA 2016; 37-411390-8103reponame:Revistas Escuela Superior Politécnica Agropecuaria de Manabíinstname:Escuela Superior Politécnica Agropecuaria de Manabíinstacron:ESPAMspahttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/112/94https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/112/707https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/112/708http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccess2025-02-25T14:33:49Zoai:espamciencia.espam.edu.ec:article/112Institucionalhttp://revistasespam.espam.edu.ec/Universidad públicahttp://www.espam.edu.ec/http://revistasespam.espam.edu.ec/oai.Ecuador.1390-81031390-597Xopendoar:02025-02-25T14:33:49Revistas Escuela Superior Politécnica Agropecuaria de Manabí - Escuela Superior Politécnica Agropecuaria de Manabífalse |
