Biochemical demonstration of malnutrition state in early weaned half-bred zebu calves
The purpose of this study was to demonstrate that early weaning, rather than stress, may induce malnutrition in calves. Sixty out of 120 half-bred zebu suckling-calves (60-75 days old) were weaned at day 0 and fed with a commercial balanced diet (group E), while the rest continued suckling (grou...

El propósito del estudio fue demostrar que el destete precoz, antes que el estrés, es capaz de provocar un estado de malnutrición en terneros. Sesenta terneros lactantes cruza cebú (60-75 días de edad) fueron destetados al día 0 y recibieron una dieta balanceada comercial (grupo E), en tanto que otros 60 continuaron amamantándose (grupo C). Se tomaron muestras de sangre a los 7, 14, 21, 28, 60, 90 y 120 días, y mediante métodos convencionales fueron medidos algunos indicadores nutricionales séricos. Comparando los resultados finales de ambos grupos, C versus E, en este último fueron registradas disminuciones séricas (p < 0.05) de las concentraciones de albúmina (3.39±0.29 versus 3.20±0.24 g/ dl), urea (0.30±0.04 versus 0.25±0.03 g/l), triglicéridos (0.36±0.10 versus 0.21±0.09 g/l), hemoglobina (13.8±1.1 versus 11.7±1.4 g/dl), hierro (112±17 versus 92±20 ug/dl), cobre (80±19 versus 59±20 ug/dl) y peso (158.7±11.7 versus 139.4±11.6 kg). Las diferencias entre C y E comenzaron a ser significativas a partir de los 7-21 días. Los resultados sugieren un estado de malnutrición en el grupo E. Al final del ensayo, todos los indicadores nutricionales tendieron a revertir su tendencia declinante, cambios que son atribuidos al crecimiento compensatorio. La ausencia de aumentos resultantes en las concentraciones séricas de urea, triglicéridos, hemoglobina y cobre, ni de alteraciones clínicas y/o muertes, descartan la existencia de estrés en los terneros precozmente destetados. 2023-04-11T21:41:26Z 2023-04-11T21:41:26Z 2004-04 Artículo Coppo, José Antonio, 2004.

| description |
The purpose of this study was to demonstrate that early weaning,
rather than stress, may induce malnutrition in calves. Sixty out of 120
half-bred zebu suckling-calves (60-75 days old) were weaned at day 0
and fed with a commercial balanced diet (group E), while the rest
continued suckling (group C). Blood samples were taken on days 0, 7, 14,
21, 28, 60, 90 and 120, and sera nutritional indicators were determined
by conventional methods. Comparing the final results of both groups, C
versus E, decreases in sera concentrations (p < 0.05) of albumin (3.39±0.29
versus 3.20±0.24 g/dl), urea (0.30±0.04 versus 0.25±0.03 g/l), triglycerides
(0.36±0.10 versus 0.21±0.09 g/l), hemoglobin (13.8±1.1 versus 11.7±1.4
g/dl), iron (112±17 versus 92±20 ug/dl), copper (80±19 versus 59±20 ug/
dl), and weight (158.7±11.7 versus 139.4±11.6 kg) were registered in group
E. Differences between C and E began to be significant from day 7 to 21.
Results suggest malnutrition in animals of group E. At the end of the
assay, the declining tendency of nutritional indicators tended to revert
to normal values. Such changes are attributed to compensatory growth.
The absence of a consequential increment in sera urea, triglycerides,
hemoglobin and copper concentrations, neither clinical alterations nor deaths, discount the existence of stress in early weaned calves. |
