Descripción del Articulo

The aim of this study was to know the levels of phosphorus and its effects on feed intake and body weight in female alpacas during the breeding season (January-February) and weaning (August-September). In the first phase, serum phosphorus levels were determined in 200 11-13-month-old alpacas, locate...

dc.description.none.fl_txt_mv The aim of this study was to know the levels of phosphorus and its effects on feed intake and body weight in female alpacas during the breeding season (January-February) and weaning (August-September). In the first phase, serum phosphorus levels were determined in 200 11-13-month-old alpacas, located in four alpaca regions of Peru. P levels were 8.25 ± 1.63, 5.25 ± 1.46, 6.42 ± 1.84 and 4.8 ± 1.61 mg/dl for the regions of Pasco, Junín, Cuzco and Puno, respectively, with significant differences (p<0.05) between regions. P values in one region were below the reference limit (5-11.5 mg/dl) and the another near the lower limit, which could be considered as deficient in P. In the second phase, a controlled experiment was carried out with three concentrations of P in the diet: 0.16% (T1), 0.25% (T2) and 0.34% (T3), using 16 weaned female alpacas per group (7-8 months, 25.25 ± 1.62 kg). The animals received the feeds ad libitum and were housed in individual pens for seven months. Dry matter intake was 0.717±0.82, 0.826±0.82 and 0.967±0.49 kg/animal/day and as a percentage of live weight was 2.07, 2.24 and 2.60 for treatments T1, T2 and T3, respectively. In both cases there were significant differences between treatments (p<0.05). There was a significant reduction in the concentration of P in T1 (5.02±1.11 mg/dl) compared to T2 (11.07±1.79 mg/dl) and T3 (11.45±1.14 mg/dl). It is likely that low dietary phosphorus in T1 may have affected consumption and weight gain in growing alpacas.
El estudio tuvo como objetivo conocer los niveles de fósforo y sus efectos sobre el consumo de alimento y peso vivo en alpacas hembras durante la temporada de reproducción (enero-febrero) y el destete (agosto-septiembre). En la primera etapa se determinaron los niveles séricos de fósforo en 200 alpacas de 11-13 meses de edad, ubicadas en cuatro regiones alpaqueras del Perú. Los niveles de P sérico fueron de 8.25±1.63, 5.25±1.46, 6.42±1.84 y 4.8±1.61 mg/dl para los animales de las regiones de Pasco, Junín, Cuzco y Puno, respectivamente, habiendo diferencias significativas (p<0.05) entre regiones. Una región se encontró por debajo del límite de referencia (5-11.5 mg/dl) y otra cerca del límite inferior, pudiendo considerarse como deficientes en P. En la segunda etapa se realizó un experimento controlado con tres concentraciones de P en la dieta: 0.16% (T1), 0.25% (T2) y 0.34% (T3), con 16 alpacas hembras destetadas (7-8 meses, 25.25±1.62 kg) por grupo. Los animales recibieron alimentación ad libitum y estuvieron alojados en corrales individuales durante siete meses. El consumo de materia seca fue de 0.717±0.82, 0.826±0.82 y 0.967±0.49 kg/animal/día, mientras que, como porcentaje del peso vivo fue 2.07, 2.24 y 2.60 para los tratamientos T1, T2 y T3, respectivamente. En ambos casos hubo diferencias significativas entre tratamientos (p<0.05). Hubo una reducción significativa en la concentración de P en T1 (5.02±1.11 mg/dl) comparado con T2 (11.07±1.79 mg/dl) y T3 (11.45±1.14 mg/dl). Es probable que el bajo fósforo dietario en T1 pudo haber afectado el consumo y la ganancia de peso en alpacas en crecimiento.
