Colostrum quality and composition
Livestock, 2023Colostrum, the first milk produced by the cow before calving, is functionally and compositionally distinct from whole milk. Differences in fat, carbohydrate, protein, vitamin and mineral concentrations provide nutrition for the neonate. A high lipid content is an indispensable source of energy, while protein aids development and vitamins and minerals ...

Colostrum is the first milk secreted by mammary gland following birth and it is secreted within the first week after calving. It has many benefical components for neonates. Colostrum has protective features against pathogens and affects viability and growth of the calves. Due to the placental structure of ruminants, calves born agammaglobulinemic.

Quality Assessment of Bovine and Equine Colostrum – An Overview
Schweiz Arch Tierheilkd, 2019Good quality colostrum intake is essential for passive immunity in neonatal calf and foals. The quality of colostrum depends on its IgG content. Since in practice the possibilities for a direct determination of these parameter are limited, an estimation of colostrum quality is often based on its biophysical properties.

Evaluation of goat colostrum quality by determining enzyme activity levels
Livestock Production Science, 2003The potential use of colostral enzymes for the determination of colostrum quality in goats was evaluated. The enzymes gamma glutamyltransferase (GGT), lactic dehydrogenase (LDH) and alkaline phosphatase (ALP) were measured in goat colostrum, milked within 6 h after birth.

Determination of colostrum quality using Brix refractometer in sheep
Acta Veterinaria HungaricaAbstractIn this study, we aimed to determine the quality of colostrum in sheep by using Brix refractometer. The research included 100 sheep of Merino X Kivircik crossbred. From each, we collected 15 mL of colostrum samples in falcon tubes within the first 8 h after delivery. Mean colostral IgG level of sheep was 156.68 ± 7.23 g L−1, optical and digital
