TL;DR:
Cows weaning calves after 10 mo of lactation were lighter than cows weaned after 7 mo; however, calves remaining with their dam maintained growth rates similar to grain supplemented weaned calves on pasture.

TL;DR:
While treatments influenced cow measures, all remained within normal values, therefore late weaning may be an option for producers to sell heavier calves without grain supplementation if marketing older calves.

Influence of weaning strategy on behavior, humoral indicators of stress, growth, and carcass characteristics
Translational Animal Science, 5(1), txaa231.
author keywords: activity; behavior; carcass characteristics; hormones; weaning strategy
TL;DR:
Based on ADG during the 42 d after weaning, it is recommend delaying weaning when available pasture and cow body condition support this strategy, and abrupt weaning under the conditions of this study, is less stressful than it is perceived to be.

TL;DR:
Based on the data, exposure to low to moderate levels of ergot alkaloids during the stocker phase had a negative impact on hemodynamic responses and supplemental CP had minimal impact to alleviate symptoms and feeding additional protein above established requirements is not expected to help alleviate fescue toxicosis.

2011 journal article
Restriction of vitamin A and D in beef cattle finishing diets on feedlot performance and adipose accretion
Journal of Animal Science, 90(6), 1866–1878.
author keywords: adiposity; bovine; feedlot performance; vitamin A; vitamin D
MeSH headings : Adipose Tissue / drug effects; Animal Feed / analysis; Animal Nutritional Physiological Phenomena; Animals; Body Composition / drug effects; Cattle / physiology; Diet / veterinary; Dietary Supplements; Male; Vitamin A / blood; Vitamin A / chemistry; Vitamin A / pharmacology; Vitamin D / blood; Vitamin D / chemistry; Vitamin D / pharmacology; Weight Gain / drug effects
TL;DR:
As retinol and 25(OH)D(3) concentrations in feedlot cattle declined as a result of a lack of dietary supplementation, adipose accretion increased, resulting in elevated Quality and Yield grades, and withdrawal of supplemental vitamin A, D, or both from the finishing diet of feedlot beef cattle had minimal impact carcass composition.

2011 journal article
Transient Fecal Shedding and Limited Animal-to-Animal Transmission of Clostridium difficile by Naturally Infected Finishing Feedlot Cattle
Applied and Environmental Microbiology, 77(10), 3391–3397.
MeSH headings : Animals; Bacterial Shedding; Bacterial Toxins / biosynthesis; Bacterial Typing Techniques; Carrier State / microbiology; Carrier State / veterinary; Cattle / microbiology; Clostridioides difficile / classification; Clostridioides difficile / genetics; Clostridioides difficile / isolation & purification; Clostridium Infections / microbiology; Clostridium Infections / transmission; Clostridium Infections / veterinary; Enzyme-Linked Immunosorbent Assay; Feces / microbiology; Polymerase Chain Reaction; Ribotyping
TL;DR:
Transient shedding with no evidence of animal-to-animal transmission of Clostridium difficile among finishing feedlot cattle and the subsequent need for antimicrobials for respiratory disease might indicate common predisposing factors.

Adipogenic differentiation state-specific gene expression as related to bovine carcass adiposity
Journal of Animal Science, 89(2), 355–366.
author keywords: adipose; bovine; differentiation; gene expression
MeSH headings : Abdominal Fat / cytology; Abdominal Fat / physiology; Adipocytes / cytology; Adipocytes / physiology; Adipogenesis / physiology; Animals; Cattle / genetics; Cattle / physiology; Cell Differentiation / genetics; Cell Differentiation / physiology; Gene Expression Profiling / veterinary; Gene Expression Regulation / physiology; Histocytochemistry / veterinary; Least-Squares Analysis; Male; RNA, Messenger / chemistry; RNA, Messenger / genetics; Reverse Transcriptase Polymerase Chain Reaction / veterinary; Subcutaneous Fat / cytology; Subcutaneous Fat / physiology
TL;DR:
Investigation of adipogenic differentiation state-specific gene expression in feedlot cattle of varying adipose accretion patterns found adipogenesis in the SQ and IM adipose tissues seems to occur independently.
