EVALUATION OF COLOSTRUM MANAGEMENT IN CALVES: CASE REPORT

Abstract

Adequate colostrum management is essential for the survival, health, and development of neonatal calves, as cattle depend on colostrum intake for the acquisition of passive immunity. This study aimed to monitor and evaluate colostrum quality and the efficiency of colostrum management in Purunã calves. The study was conducted at the Univel School Farm, in Cascavel, Paraná, Brazil, involving two multiparous cows and their respective female calves. During the prepartum period, colostrum/mammary secretion samples were collected to evaluate pH and Brix values. After calving, colostrum quality was assessed using a Brix refractometer, yielding values of 26% and 19%, classified as high-quality and intermediate-quality colostrum, respectively. Both calves showed good vitality, a vigorous suckling reflex, and spontaneous colostrum intake within the first two hours of life. To assess passive immunity transfer (PIT), blood samples were collected 48 hours after birth. Total protein concentrations were 6.7 g/dL and 6.5 g/dL, respectively. The results reinforce the importance of assessing colostrum quality and ensuring its early intake to achieve adequate passive immunity transfer.
