Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

Animal Research and One Health, EarlyView.
The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

Indoor versus Outdoor Calf Rearing at Three Weaning Ages

Journal of Dairy Science, 1970
Abstract Sixty Holstein calves were randomly allotted to two housing systems (inside and outside) and three weaning ages (3, 5, and 7 weeks) within each housing system. Individual outdoor calf hutches and individual pens in an insulated heated barn were utilized for the initial 14 weeks.

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

Animal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Effects of Calf Age at Weaning on Cow and Calf Performance and Feed Utilization in an Intensive Production System

, 2015
The effects of calf weaning age on cow and calf performance, reproduction, and feed utilization were investigated in a two-year study. Early weaning increasedcow BW in January. Pregnancy rates were not impacted by calf age at weaning.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

An ABCA12 missense variant in a Shorthorn calf with ichthyosis fetalis.

, 2019
Two clinical forms of ichthyosis in cattle have been reported, ichthyosis fetalis and congenital ichthyosis. Ichthyosis poses animal welfare and economic issues and the more severe form, ichthyosis fetalis, is lethal.

Indole‐3‐Acetic Acid Protects Bovine Hepatocytes Against Palmitic Acid‐Induced Lipid Accumulation and ER Stress Through SIRT3

Animal Research and One Health, EarlyView.
Cows with ketosis during the perinatal period often experience damage to the liver, a core metabolic organ, thereby exacerbating the disease's inherent vicious cycle. This study indicates that serum 3‐IAA concentrations were reduced in ketotic cows and show a significant negative correlation with hepatic TG content.

Plasma and Blood Volume in the Calf from Birth Till 90 Days of Age

Acta Veterinaria Scandinavica, 1975
Determinations of plasma volume were made of 9 clinically healthy Swedish Red and White calves from birth to 90 days of age by means of the isotop dilution technique. Commercially available 131I labelled human serum albumin was used. Calculation of the total blood volume was based on the plasma volume and packed cell volume.
