Delayed First Milking in Unassisted Overnight Calving Did Not Affect the Quality of Colostrum but Influenced Serum Brix Refractometry in Holstein Calves at Two Days of Life

open access: yesAnimals, 2022
Timely administration of good-quality colostrum represents the first farm strategy to avoid the failure of passive transfer (FPT). However, calves born during the night are likely to be fed later than recommended.

Validation of Brix refractometer to estimate immunoglobulin G concentration in goat colostrum [PDF]

open access: yesVeterinary World, 2021
Background and Aim: Immunoglobulin G (IgG) concentration is high in goat colostrum, particularly in the first few hours after parturition, and this is important for the kid's immunity and growth.

Bovine Colostrum: Human and Animal Health Benefits or Route Transmission of Antibiotic Resistance—One Health Perspective

open access: yesAntibiotics, 2023
After calving, bovine colostrum is obtained from the mammary gland of the dam in the first days and fed to newborn ruminant to prevent microbial infections. Each bovine colostrum has a unique biochemical composition with high nutraceutical value compared

Effects of dietary rumen-protected choline supplementation on colostrum yields, quality, and choline metabolites from dairy cattle

open access: yesJDS Communications, 2022
Colostrum is a critical nutrient source that provides passive immunity to dairy calves. Choline is a trimethylated molecule that is frequently supplemented in the diet to periparturient dairy cows to support postpartum health and performance.

The Effect of Parity on the Quality of Colostrum of Holstein Dairy Cows in the Organic Production System

open access: yesAnimals, 2023
A special feature of organic production systems is the cows’ significantly lower productivity, which is adapted to environmental conditions. The quantity and quality of colostrum is negatively correlated, high amounts of colostrum are associated with low

Bovine Colostrum for Human Consumption—Improving Microbial Quality and Maintaining Bioactive Characteristics through Processing

open access: yesDairy, 2021
The main purpose of bovine colostrum, being the milk secreted by a cow after giving birth, is to transfer passive immunity to the calf. The calves have an immature immune system as they lack immunoglobulins (Igs). Subsequently, the supply of good quality

A Scoping Review of On-Farm Colostrum Management Practices for Optimal Transfer of Immunity in Dairy Calves

open access: yesFrontiers in Veterinary Science, 2021
Newborn calves are agammaglobulinemic and rely for their first immune protection almost completely on the transfer of immune constituents via colostrum.

Evaluation of on-farm tools for colostrum quality measurement [PDF]

open access: yesJournal of Dairy Science, 2015
The objectives of this study were to determine the immunoglobulin G (IgG) content of colostrum on Alberta dairy farms and to determine which on-farm tool, the colostrometer or the Brix refractometer, was more highly correlated with IgG content as determined by radial immunodiffusion (RID).

The Quality of Colostrum and Its Effects on Calves Growth Characteristics in Holstein Cattle

open access: yesJournal of Agricultural Sciences, 2007
This study was carried out to determine colostrum quality in Holstein Cows. Colostrum quality has been estimated by using a colostrometer. The colostrometer works by measuring the specific gravity of colostrum and then takein advantage of the linear ...
