Comparison of blood urea nitrogen level between weaned alpacas and llamas grazing cultivated pastures

Descripción del Articulo

The aim of this study was to compare the level of blood urea nitrogen (BUN) between weaned alpacas and llamas grazing cultivated pastures. It was used 63 alpacas and 64 llamas, both females and males, maintained for 21 days after weaning on cultivated pastures (association of Italian rye grass [Loli...

dc.description.none.fl_txt_mv The aim of this study was to compare the level of blood urea nitrogen (BUN) between weaned alpacas and llamas grazing cultivated pastures. It was used 63 alpacas and 64 llamas, both females and males, maintained for 21 days after weaning on cultivated pastures (association of Italian rye grass [Lolium multiflorum] and white clover [Trifolium repens]). The blood sample was taken on day 21 of the study before animals went for grazing. The chemical composition of the offered feed, BUN and the selectivity index (SI) were evaluated. The BUN determination was done by visible UV spectrophotometry with a commercial kit. The IS was determined between the botanical composition of the pasture and the botanical composition of feed consumed. The data were analyzed through the Student t test of two samples with equal variances. The chemical composition of the cultivated grass offered for dry matter, crude protein, crude fiber, ethereal extract and ash was 18.09, 16.30, 19.20, 1.43 and 6.60%, respectively. BUN values in alpacas and llamas were 19.04 ± 3.24 mg/dl (12.13 - 26.36 mg/dl) and 19.05 ± 3.93 mg/dl (8.80 - 25.69 mg/dl), respectively, without significant difference between species. The IS was neutral, and no selectivity was found in both species. It is concluded that BUN is similar between weaned alpacas and llamas grazing cultivated pastures and they did not show selectivity for consumption.
El presente estudio tuvo como objetivo comparar el nivel del nitrógeno ureico san-guíneo (NUS) entre alpacas y llamas destetadas, mantenidas en pastos cultivados. Se utilizaron 63 alpacas y 64 llamas, tanto hembras como machos, mantenidas por 21 días luego del destete sobre pasturas cultivadas (asociación de rye grass italiano [Lolium multiflorum] y trébol blanco [Trifolium repens]). La toma de la muestra de sangre se hizo el día 21 antes que salgan a pastorear. Se evaluó la composición química del alimento ofrecido, el NUS y el índice de selectividad (IS). La determinación del NUS se hizo por espectrofotometría UV visible con un kit comercial. El IS se determinó entre la composi-ción botánica del potrero y la composición botánica del consumo. Los datos fueron analizados a través de la prueba de t Student de dos muestras con varianzas iguales. La composición química del pasto cultivado ofrecido para el caso de materia seca, proteína cruda, fibra cruda, extracto etéreo y ceniza fue de 18.09, 16.30, 19.20, 1.43 y 6.60%, respec-tivamente. Los valores de NUS en alpacas y llamas fueron de 19.04 ± 3.24 mg/dl (12.13 - 26.36 mg/dl) y 19.05 ± 3.93 mg/dl (8.80 - 25.69 mg/dl), respectivamente, sin diferencia significativa entre especies. El IS fue neutro, no encontrándose selectividad en ambas especies. Se concluye que el NUS es similar entre alpacas y llamas destetadas manteni-das en pasturas cultivas y que no presentaron selectividad para el consumo.
