| description |
Reproductive efficiency and neonatal survival are critical determinants of productivity in buffalo farming systems. The objective of this study was to evaluate incisor eruption and to assess morphometric, hematological, and biochemical parameters in neonatal buffalo calves during the first week of life. Twenty neonatal buffalo calves (1–7 days old), equally distributed by breed (Murrah and Mediterranean) and sex, raised in Corrientes, Argentina, were included. The number of erupted incisors, body weight, thoracic girth, and hematological and biochemical parameters were recorded using standardized methods. Data were analyzed by ANOVA, and the 5th–95th percentiles as well as 95% confidence intervals were calculated (p<0.05). Forty-seven percent of the calves had four erupted incisors, 37% had two, and 16% had six, with no significant differences between sexes or breeds. However, significant differences were observed: Mediterranean calves were heavier than Murrah calves (39.57 ± 1.45 vs. 33.56 ± 1.68 kg; p<0.02), and males showed greater body weight (37.56 ± 3.22 vs. 34.67 ± 2.14 kg; p<0.04) and thoracic girth (88.22 ± 2.33 vs. 85.33 ± 3.58 cm; p<0.02) compared with females. Regarding hematological and biochemical parameters, males had significantly higher values of hematocrit (38.03 ± 2.02% vs. 35.15 ± 2.19%; p<0.04), erythrocyte count (8.03 ± 0.47 vs. 7.28 ± 0.51106 μl-¹; p<0.03), alkaline phosphatase (613.01 ± 37.09 vs. 513.83 ± 29.52 U·L-¹; p<0.02), and LDH (261.32 ± 18.75 vs. 227.23 ± 17.60 U·L-¹; p<0.03). Conversely, females showed higher concentrations of total protein (7.07 ± 0.93 vs. 6.27 ± 0.67 g·dL-¹; p<0.03), albumin (1.89 ± 0.44 vs. 1.63 ± 0.39 g·dL-¹; p<0.04), and triglycerides (1.08 ± 0.18 vs. 0.76 ± 0.20 g·L-¹; p<0.04). These findings constitute the first report of sexual dimorphism in hematological and biochemical parameters during the first week of life in buffalo calves and provide valuable reference values for sex-specific neonatal management and the optimization of rearing protocols in subtropical production systems. |

La eficiencia reproductiva y la supervivencia neonatal son factores importantes para mejorar la productividad en los sistemas bubalinos. El objetivo de este estudio fue evaluar la erupción dentaria y analizar parámetros morfométricos, hematológicos y bioquímicos en bucerros durante la primera semana de vida. Se estudiaron 20 búfalos neonatos (1-7 días de edad), equitativamente distribuidos entre las razas Murrah y Mediterránea y de ambos sexos, criados en Corrientes, Argentina. Se registraron el número de incisivos erupcionados, peso vivo, perímetro torácico y parámetros sanguíneos mediante métodos estandarizados. Los datos fueron analizados mediante ANOVA, y se calcularon los percentiles 5-95 e intervalos de confianza del 95% (p<0,05). El 47% presentó cuatro incisivos erupcionados, el 37% dos y el 16% seis, sin diferencias significativas por sexo o raza. No obstante, se hallaron variaciones significativas: los Mediterránea superaron en peso a los Murrah (39,57 ± 1,45 vs. 33,56 ± 1,68 kg; p<0,02), y los machos mostraron mayor peso (37,56 ± 3,22 vs. 34,67 ± 2,14 kg; p<0,04) y perímetro torácico (88,22 ± 2,33 vs. 85,33 ± 3,58 cm; p<0,02) que las hembras. En cuanto a los parámetros sanguíneos, los machos presentaron valores superiores de hematocrito (38,03 ± 2,02% vs. 35,15 ± 2,19%; p<0,04), eritrocitos (8,03 ± 0,47 vs. 7,28 ± 0,51 106 μl-¹; p<0,03), fosfatasa alcalina (613,01 ± 37,09 vs. 513,83 ± 29,52 UI L-1; p<0,02) y LDH (261,32 ± 18,75 vs. 227,23 ± 17,60 UI L-1; p<0,03). Las hembras mostraron mayores niveles de proteínas totales (7,07 ± 0,93 vs. 6,27 ± 0,67 g dL-1; p<0,03), albúmina (1,89 ± 0,44 vs. 1,63 ± 0,39 g dL-1; p<0,04) y triglicéridos (1,08 ± 0,18 vs. 0,76 ± 0,20 g L-1; p<0,04). Estos resultados constituyen el primer reporte de dimorfismo sexual en parámetros hematológicos y bioquímicos durante la primera semana de vida en búfalos, y proporcionan valores de referencia útiles para el manejo neonatal diferenciado y la mejora de los protocolos de crianza en sistemas de producción subtropicales.
