Front Physiol . 2022 Sep; 13:912797. PMID: 36117708
This study was conducted to investigate the effects of different dosages of tannic acid (TA) on growth performance, nutrient digestibility, gut health, immune system, oxidative status, microbial composition, volatile fatty...

Jeon J, Lourenco J, Fagan M, Welch C, Sneed S, Dubrof S, et al.
Brain Sci . 2022 Aug; 12(8). PMID: 36009173
Dynamic changes in the oral microbiome have gained attention due to their potential diagnostic role in neurological diseases such as Alzheimer's disease and Parkinson's disease. Traumatic brain injury (TBI) is...

Seidel D, Walker J, Musser J, Lourenco J, Welch C, Whitney T, et al.
Transl Anim Sci . 2022 Aug; 6(3):txac098. PMID: 35959416
The microbial population in the gastrointestinal tract of ruminant animals aids in the utilization of forages with high levels of secondary plant compounds. Two divergent bloodlines of meat goats have...

Welch C, Ryman V, Pringle T, Lourenco J
Microorganisms . 2022 Jul; 10(7). PMID: 35889109
The microorganisms inhabiting the gastrointestinal tract (GIT) of ruminants have a mutualistic relationship with the host that influences the efficiency and health of the ruminants. The GIT microbiota interacts with...

Lourenco J, Welch C, Krause T, Wieczorek M, Fluharty F, Rothrock M, et al.
Microorganisms . 2022 Jun; 10(6). PMID: 35744646
The gastrointestinal microbiota of cattle is important for feedstuff degradation and feed efficiency determination. This study evaluated the fecal microbiome of Angus steers with distinct feed efficiencies during the feedlot-finishing...

Lourenco J, Krause T, Welch C, Callaway T, Pringle T
Animals (Basel) . 2022 May; 12(9). PMID: 35565493
The ruminal microbiota of Angus cows and steers were characterized using 16s rRNA gene sequencing, and the expression of their metabolic pathways was predicted. Samples were collected on weaning day...

Mote R, Hill N, Skarlupka J, Carpenter J, Lourenco J, Callaway T, et al.
Sci Rep . 2022 Mar; 12(1):4899. PMID: 35318361
Bovine fescue toxicosis (FT) is caused by grazing ergot alkaloid-producing endophyte (Epichloë coenophiala)-infected tall fescue. Endophyte's effects on the animal's microbiota and metabolism were investigated recently, but its effects in...

Welch C, Lourenco J, Seidel D, Krause T, Rothrock M, Pringle T, et al.
Microorganisms . 2021 Dec; 9(12). PMID: 34946226
Diet impacts the composition of the ruminal microbiota; however, prior to slaughter, cattle are fasted, which may change the ruminal microbial ecosystem structure and lead to dysbiosis. The objective of...

Animals (Basel) . 2021 Dec; 11(12). PMID: 34944205
The purpose of the study was to investigate effects of different inoculation dosages of on growth performance, gastrointestinal permeability, oocyst shedding, intestinal morphology, fecal consistency, ileal apparent digestibility, antioxidant capacity,...

Front Vet Sci . 2021 Jul; 8:597405. PMID: 34268344
Numerous studies have examined the link between the presence of specific gastrointestinal bacteria and the feed efficiency of cattle. However, cattle undergo dietary changes during their productive life which can...
