Use of dicarboxylic acids and polyphenols to attenuate reticular pH drop and acute phase response in dairy heifers fed a high grain diet
(2014-11-26)
Abstract
Background
The aim of this study was to determine the ability of two feed additives, a fumarate-malate (FM) and a ...
Saccharomyces cerevisiae fermentation products (SCFP) stabilize the ruminal microbiota of lactating dairy cows during periods of a depressed rumen pH
(2020-07-11)
Abstract
Background
Effects of Saccharomyces cerevisiae fermentation products (SCFP) on rumen microbiota were determined in vitro and in vivo under a high and a depressed pH. The in vitro trial determined the effects of ...
Associations between digital dermatitis lesion grades in dairy cattle and the quantities of four Treponema species
(2018-10-29)
Abstract
Digital dermatitis (DD) presents as painful, ulcerative or proliferative lesions that lead to bovine lameness affecting economic efficiency and animal welfare. Although DD etiological agent(s) have ...
Association of bovine major histocompatibility complex (BoLA) gene polymorphism with colostrum and milk microbiota of dairy cows during the first week of lactation
(2018-11-12)
Abstract
Background
The interplay between host genotype and commensal microbiota at different body sites can have important implications for health and disease. In dairy cows, ...
Indicators of induced subacute ruminal acidosis (SARA) in Danish Holstein cows
(2015-07-17)
Abstract
Background
The prevalence of subacute ruminal acidosis (SARA) in dairy cows is high with large impact on economy and welfare. Its current field diagnosis is based on ...
Bacteria in drinking water sources of a First Nation reserve in Canada
(Elsevier, 2016-09-29)
Approximately 20% of the 600 First Nations reserves across Canada are under a drinking water advisory, often due to unacceptable levels of bacteria. In this study, we detected fecal bacteria at an alarmingly high frequency ...
Metagenomic analysis of rumen microbial population in dairy heifers fed a high grain diet supplemented with dicarboxylic acids or polyphenols
(2016-02-19)
Abstract
Background
The aim of this study was to investigate the effects of two feed supplements on rumen bacterial communities of heifers fed a high grain diet. Six ...
Composition and co-occurrence patterns of the microbiota of different niches of the bovine mammary gland: potential associations with mastitis susceptibility, udder inflammation, and teat-end hyperkeratosis
(2020-04-14)
Abstract
Background
Within complex microbial ecosystems, microbe-microbe interrelationships play crucial roles in determining functional properties such as metabolic potential, stability and colonization resistance. In ...
