Body weight gain and carcass yield of llamas (Lama glama) subjected to fattening under four feeding types
Descripción del Articulo
The aim of this study was to evaluate the bodyweight gain and carcass yield of young male llamas (milk tooth) subjected to fattening with four types of feeding (T1: Natural pasture; T2: T1 + vitamin injection; T3: T1 + alfalfa hay; T4: T2 + hay alfalfa). A completely randomized design with a 2x2 fac...

Body weight gain and carcass yield of llamas (Lama glama) subjected to fattening under four feeding typesGanancia de peso y rendimiento de carcasa de llamas (Lama glama) dientes de leche sometidas a engorde con cuatro tipos de alimentaciónRobles, RicardoHidalgo, VíctorWurzinger, MaríaGutierrez, Gustavocarcass dressing percentagefatteningllamarendimiento de carcasaengordellamasThe aim of this study was to evaluate the bodyweight gain and carcass yield of young male llamas (milk tooth) subjected to fattening with four types of feeding (T1: Natural pasture; T2: T1 + vitamin injection; T3: T1 + alfalfa hay; T4: T2 + hay alfalfa). A completely randomized design with a 2x2 factorial arrangement with a covariance analysis (initial live weight as covariate) was used. Thirty-two llamas were randomized assigned to one of the four treatments for 84 days. The stocking rate was 1.3 animal units/ha. Daily weight gain (DWG) was evaluated in the fattening periods at 14, 28, 42, 56, 70 and 84 days. The DWG per fattening period was significantly different between periods, in the first three periods (14, 28 and 42 days) showing the best DWG (337, 237 and 160 g/d, respectively). The DWG per feed type was higher in T3 (157 g/d) during the 84-day period (p<0.01) and the best carcass yield was obtained in T4 (53.60%) followed by T3 (53.20%) (p<0.01). It is concluded that the highest DWG is achieved at day 42 and the best carcass yield is obtained with natural pasture + alfalfa hay supplementation (T3).El objetivo del estudio fue evaluar la ganancia de peso y rendimiento de carcasa de llamas machos diente de leche sometidas a engorde con cuatro tipos de alimentación (T1: Pastura natural; T2: T1 + dosificación vitamínica; T3: T1 + heno de alfalfa; T4: T2 + heno de alfalfa). Se utilizó un diseño completamente al azar con arreglo factorial de 2x2 con un análisis de covarianza (peso vivo inicial como covariable). Se emplearon 32 llamas asignadas al azar a uno de los cuatro tratamientos por 84 días. La carga animal empleada fue de 1.3 unidades llama/ha. La ganancia diaria de peso (GDP) se evaluó en los periodos de engorde a 14, 28, 42, 56, 70 y 84 días. La GDP por periodo de engorde fue significativamente diferente entre periodos, donde los primeros tres periodos (14, 28 y 42 días) mostraron mejor GDP (337, 237 y 160 g/d, respectivamente). La GDP por tipo de alimentación fue mayor en T3 (157 g/d) durante el periodo de 84 días (p<0.01) y el mejor rendimiento de carcasa se obtuvo en T4 (53.60%) seguido por el T3 (53.20%) (p<0.01). Se concluye que la mayor GDP se logra hasta los 42 días y el mejor rendimiento de carcasa se logra en la pastura natural + suplementación con heno de alfalfa (T3).Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2020-03-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/1754710.15381/rivep.v31i1.17547Revista de Investigaciones Veterinarias del Perú; Vol. 31 Núm. 1 (2020); e17547Revista de Investigaciones Veterinarias del Perú; Vol. 31 No. 1 (2020); e175471682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/17547/14810Derechos de autor 2020 Ricardo Robles, Víctor Hidalgo, María Wurzinger, Gustavo Gutierrezhttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/175472020-03-30T00:45:29Z |
