Preliminary Study of Microbiological and Immunological Quality of Sheep Colostrum: Influence on Early Postnatal Weight Change
Abstract
Colostrum is crucial for the survival, development, and the future productivity of newborns. In this study, we evaluated the immunological and microbiological quality of colostrum in 28 Rasa Aragonesa ewes and its relationship with offspring growth during the first 48 h postpartum. Colostrum samples were collected by hand milking immediately after parturition. Immunoglobulin concentration was assessed using Brix refractometry and the samples were categorised according to their immunoglobulin content: high (>24 Brix value), medium (19–23 Brix value), and low (
