Rumen Fermentation, Digestive Enzyme Activity, and Bacteria Composition between Pre-Weaning and Post-Weaning Dairy Calves

open access: yesAnimals, 2021
To better understand the transition of rumen function during the weaning period in dairy calves, sixteen Holstein dairy calves were selected and divided into two groups: pre-weaning (age = 56 ± 7 day, n = 8) and post-weaning (age = 80 ± 6 day, n = 8 ...

The complex microbiota of raw milk [PDF]

open access: yesFEMS Microbiology Reviews, 2013
Here, we review what is known about the microorganisms present in raw milk, including milk from cows, sheep, goats and humans. Milk, due to its high nutritional content, can support a rich microbiota. These microorganisms enter milk from a variety of sources and, once in milk, can play a number of roles, such as facilitating dairy fermentations (e.g ...

THE NECESSITY OF A PURE RAW MILK [PDF]

open access: yesJournal of the American Medical Association, 1917
Goethe once remarked that blood is a very peculiar juice. We can say the same of milk. Modern physiologic researches have shown that certain glands and secretions of the body have much larger functions than have hitherto been assigned to them. We need only refer to the internal secretions of various glands, formerly unrecognized, that are now known to ...

The Blood Immune Cell Count, Immunoglobulin, Inflammatory Factor, and Milk Trace Element in Transition Cows and Calves Were Altered by Increasing the Dietary n-3 or n-6 Polyunsaturated Fatty Acid Levels

open access: yesFrontiers in Immunology, 2022
Transition dairy cows experience sudden changes in both metabolic and immune functions, which lead to many diseases in postpartum cows. Therefore, it is crucial to monitor and guarantee the nutritional and healthy status of transition cows. The objective

Incidence of Colostrum in Raw Milk

open access: yesJournal of Food Protection, 1993
A survey was conducted to determine the colostrum content in raw milk from dairies in Manitoba, Canada. Colostrum was indirectly measured by the determination of bovine immunoglobulin G (IgG) using a radial immunodiffusion assay. The results showed that 360 milk samples, which accounted for 89% of the total tested samples, were contaminated with ...
