Resumen

Objetivo. Evaluar las relaciones entre peso corporal, condición corporal y producción de leche en respuesta a la suplementación con semilla de algodón. Materiales y métodos. Se utilizaron 13 vacas y se conformaron dos grupos de tratamientos utilizando un diseño al azar: G1 (n=7) vacas suplementadas con 2 kg. de semilla de algodón; G2 (n=6) vacas no suplementadas. Para el análisis de resultados se emplearon correlaciones de Spearman. Resultados. Se presentaron correlaciones positivas entre la variación de peso corporal y condición corporal (p0.05) en las vacas suplementadas; por el contrario se presentaron correlaciones positivas (p0.05). Conclusiones. La suplementación con semilla de algodón presentó relaciones positivas importantes entre la variación del peso, condición corporal y producción de leche en vacas de primer parto manejadas bajo condiciones de pastoreo.
