Influence of weaning strategy on behavior, humoral indicators of stress, growth, and carcass characteristics

Translational Animal Science, 5(1), txaa231.

By: S. Freeman n, M. Poore n, C. Pickworth n & M. Alley*

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. (via Semantic Scholar)

By: J. Jee*, A. Hoet*, M. Azevedo*, A. Vlasova*, S. Loerch*, C. Pickworth*, J. Hanson*, L. Saif*

MeSH headings : Animals; Antibodies, Viral / drug effects; Cattle / immunology; Coronavirus, Bovine / immunology; DNA Primers / genetics; Dietary Supplements; Enzyme-Linked Immunosorbent Assay / veterinary; Immunoglobulin G / blood; Injections, Intramuscular / veterinary; Real-Time Polymerase Chain Reaction; Reverse Transcriptase Polymerase Chain Reaction; Statistics, Nonparametric; Vaccines, Inactivated / administration & dosage; Vaccines, Inactivated / immunology; Vitamin A / blood; Vitamin A / pharmacology
TL;DR: A low vitamin A diet compromised the serum IgG1 responses against inactivated BCoV vaccine, which suggested suppressed T-helper 2-associated antibody (IgG1) responses, which may compromise the effectiveness of viral vaccines and render calves more susceptible to infectious disease.

author keywords: carotenoid; cattle; vitamin A
MeSH headings : Animal Feed / analysis; Animal Nutritional Physiological Phenomena; Animals; Carotenoids / analysis; Carotenoids / metabolism; Cattle / metabolism; Diet / veterinary; Nutritional Requirements; Vitamin A / metabolism
TL;DR: Overall, there was considerable variation in the pro-vitamin A content of feedstuffs based on location and storage conditions, and an extensive analysis ofFeedstuffs would need to be conducted for an accurate estimation of the vitamin Acontent of feedlot cattle diets. (via Semantic Scholar)

TL;DR: Two feedlot studies were conducted to investigate the timing and duration of supplemental vitamin A withdrawal from feedlot cattle (Bos taurus) diets to reduce intramuscular adipose tissue vitamin A concentration and improve carcass quality. (via Semantic Scholar)

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.

By: C. Pickworth*, S. Loerch* & F. Fluharty*

author keywords: adiposity; bovine; feedlot performance; vitamin A; vitamin D

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.
