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

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 ...

Short communication: Comparative estimation of colostrum quality by Brix refractometry in bovine, caprine, and ovine colostrum

open access: yesJournal of Dairy Science, 2021
Newborn ungulates depend on the timely supply of colostrum containing sufficient immunoglobulins to obtain passive immunity against disease. Brix refractometry enables a rapid on-farm estimation of colostrum quality and has been intensively studied in bovines.

Bovine Colostrum Management and the Factors Influencing its Quality

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The mammary gland's secretion, called colostrum, is synthesized throughout the last weeks of pregnancy and the first few days following calving. It is meant to give the calf the necessary nutrients and physiologically active substances.

Heat treatment of colostrum increases immunoglobulin G absorption efficiency in high-, medium-, and low-quality colostrum [PDF]

open access: yesJournal of Dairy Science, 2014
Previous studies with heat-treated colostrum fed to neonatal calves have consistently used average-quality colostrum. Studies have not compared colostrum across a range of immunoglobulin levels. This study was conducted to investigate IgG absorption in neonatal dairy calves using colostrum of various qualities.

Preliminary quality assessment of bovine colostrum

open access: yesItalian Journal of Food Safety, 2013
Data on bovine colostrum quality are scarce or absent, although Commission Regulations No 1662/2006 and No 1663/2006 include colostrum in the context of chapters on milk. Thus the aim of the present work is to study some physical, chemical, hygiene and safety quality parameters of bovine colostrum samples collected from Sicily and Calabria dairy herds.

Sensitive detection systems for infectious agents in xenotransplantation*

open access: yesXenotransplantation, EarlyView., 2020
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

Effect of Bovine Colostrum Dietary Supplementation on Rabbit Meat Quality

open access: yesFoods, 2022
Bovine colostrum (BC) is rich in nutrients, antimicrobial, and antioxidant factors; for these reasons, it has been used as supplement in animal nutrition. However, its possible effects on meat quality have not been studied yet. Thirty-nine New Zealand White rabbits (n = 13/group) were assigned to three groups and fed until slaughter with a commercial ...

Nation-Wide Evaluation of Colostrum Quality

open access: yes, 2012
Samples of maternal colostrum (MC) were collected from 67 farms in 12 states between June and October, 2010 to determine IgG concentration and bacterial contamination. Samples were identified by breed, lactation, and if the sample was fresh, refrigerated or frozen prior to collection. Concentration of IgG in MC ranged from < 1 to 200 mg/ml, with a mean
