Distribution difference of colostrum-derived B and T cells subsets in gilts and sows.

PLoS ONE, 2021
Piglets are highly vulnerable to infections, but colostrum provides them with some protection. The function of colostrum components is unknown, as is if the amount and subsets of leukocytes in colostrum differ between gilts and sows.

Spatio‐temporal characteristics of the gastrointestinal resistome in a cow‐to‐calf model and its environmental dissemination in a dairy production system

iMeta, EarlyView.
This study revealed spatio‐temporal characteristics of gastrointestinal resistome in a cow‐to‐calf model and the pattern of their spread to the environment and offspring in the dairy production system. The gastrointestinal tract of dairy cows is a natural reservoir of resistomes and distinguished by gut sites and regions.

Analysis of the developing gut microbiota in young dairy calves—impact of colostrum microbiota and gut disturbances

Tropical Animal Health and Production, 2020
The aim of this study was to characterize the colostrum and fecal microbiota in calves and to investigate whether fecal microbiota composition was related to colostrum microbiota or factors associated with calf health. Colostrum samples were collected in

Enrichment of medium-quality colostrum by adding colostrum replacer, combined or not with transition milk in the feeding of dairy calves

Scientific Reports
Fifty Holstein calves were allocated in randomized blocks and distributed in a 2 × 2 factorial arrangement; (A) two sources of Ig: (1) Control: bovine colostrum (25% Brix); (2) Enriched colostrum: mid-quality bovine colostrum (20% Brix) enriched with ...

Analysis of immune-related microRNAs in cows and newborn calves

Journal of Dairy Science, 2023
: Bovine colostrum contains a high concentration of immune-related microRNAs (miRNAs) that are packaged in exosomes and are very stable. In this study, 5 immune-related miRNAs (miR-142-5p, miR-150, miR-155, miR-181a, and miR-223) were quantified in dam ...

A cross-sectional study of suckling calves’ passive immunity and associations with management routines to ensure colostrum intake on organic dairy farms

Acta Veterinaria Scandinavica, 2019
Background For suckling dairy calves, different management routines to ensure sufficient colostrum intake are applied: visual assessment, hand feeding supplemental colostrum or assistance.

Colostrum avoidance practice and associated factors among mothers of infants less than six months in Chencha District: cross-sectional study

BMC Nutrition, 2023
Background Colostrum avoidance is failure to feed first breast milk to a newborn baby for the first 2 to 3 days after delivery. The problem of avoiding colostrum is prevalent in Ethiopia. But it is not adequately addressed yet.

A gut microbiota‐bile acid axis inhibits the infection of an emerging coronavirus by targeting its cellular receptor aminopeptidase N

iMeta, EarlyView.
Bacteroides fragilis employs bile salt hydrolase to reprogram host bile acid metabolism, generating lithocholic acid that directly blocks porcine deltacoronavirus infection by disrupting spike protein‐aminopeptidase N binding, defining a microbiota‐bile acid antiviral axis with therapeutic potential against coronaviruses.

Bovine Colostrum Before or After Formula Feeding Improves Systemic Immune Protection and Gut Function in Newborn Preterm Pigs

Frontiers in Immunology, 2020
Objectives: Maternal milk is often absent or in limited supply just after preterm birth. Many preterm infants are therefore fed infant formula as their first enteral feed despite an increased risk of feeding intolerance, necrotizing enterocolitis (NEC ...

Epidemiology of bovine colostrum production in New York Holstein herds: Cow, management, and environmental factors

Journal of Dairy Science, 2023
: Adequate supply of high-quality colostrum is essential for calf health. Colostrum production, at first milking, varies between animals and seasons, but herd-level and management associations with colostrum production have not been well described.
