Effects of threonine supplementation on productive performance, carcass and organ weights of fattening guinea pigs with mixed feeding
Descripción del Articulo
The experiment aimed to evaluate the effects of five dietary levels of threonine (Thr) on growth performance, carcass characteristics, and gastrointestinal (GIT) and visceral tract development of fattening guinea pigs. In total, 40 improved 30-day-old male guinea pigs were randomly distributed in fi...

Effects of threonine supplementation on productive performance, carcass and organ weights of fattening guinea pigs with mixed feedingEfectos de la suplementación de treonina sobre el rendimiento productivo, carcasa y pesos de órganos de cuyes de engorde con alimentación mixtaParedes, ManuelCerquín, MaríaParedes, ManuelCerquín, Maríaguinea pigthreoninemixed feedingfatteningcarcasscuytreoninaalimentación mixtaengordecarcasaThe experiment aimed to evaluate the effects of five dietary levels of threonine (Thr) on growth performance, carcass characteristics, and gastrointestinal (GIT) and visceral tract development of fattening guinea pigs. In total, 40 improved 30-day-old male guinea pigs were randomly distributed in five treatments with four repetitions in a completely random design and slaughtered at 72 days of age. The diet consisted of restricted concentrated feed and green forage ad libitum. Thr supplementation was performed with L-Treonine 98.5% (L-Thr) at levels of 0, 2, 4, 6 and 8 g/kg of feed, to obtain levels of 0.55, 0.59, 0.63, 0.67 and 0.71% of Thr. Guinea pigs with 0.63% dietary Thr achieved greater weight gains, better feed conversion and higher carcass performance. The GIT with possible immunological functions reached a higher relative weight with levels of 0.67 and 0.71% of Thr. The relative weight of the spleen and heart were not affected by Thr levels, while significant differences were observed in liver, lungs and kidneys.El experimento tuvo como objetivo evaluar los efectos de cinco niveles dietéticos de treonina (Thr) sobre el rendimiento en engorde, características de la carcasa y el desarrollo del tracto gastrointestinal (TGI) y visceral de cuyes. Se trabajó con 40 cuyes machos mejorados de 30 días de edad distribuidos al azar en 5 tratamientos con cuatro repeticiones en un diseño completamente aleatorio y sacrificados a los 72 días de edad. La dieta consistió en pienso restringido y forraje verde ad libitum. La suplementación de Thr se realizó con L-Treonine 98.5% (L-Thr) en niveles de 0, 2, 4, 6 y 8 g/kg de pienso, para obtener niveles de 0.55, 0.59, 0.63, 0.67 y 0.71% de Thr. Los cuyes con 0.63% de Thr dietético lograron mayores ganancias de peso, mejor conversión alimenticia y mayor rendimiento de carcasa. El TGI con posibles funciones inmunológicas alcanzó un mayor peso relativo con niveles de 0.67 y 0.71% de Thr. El peso relativo del bazo y del corazón no se afectaron por los niveles de Thr, mientras que se observaron diferencias significativas en hígado, pulmones y riñones.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2021-12-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/2170110.15381/rivep.v32i6.21701Revista de Investigaciones Veterinarias del Perú; Vol. 32 Núm. 6 (2021); e21701Revista de Investigaciones Veterinarias del Perú; Vol. 32 No. 6 (2021); e217011682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/21701/17444Derechos de autor 2021 Manuel Paredes, María Cerquínhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/217012021-12-23T08:59:55Z |
