Evaluation of Weaning Stress in Beef Calves
… within the beef cattle industry involve weaning the calf from the dam when the calf is about 205 days of age. Weaning induces a stress-response that is implicated in reducing the health and productivity of newly weaned calves. Our goal was to evaluate the impact of weaning on the stress …

Methods to Reducing Weaning Stress in Early Weaned Spring Beef Calves
<p>Reducing weaning stress in beef calves can have dramatic benefits to the health, growth, and performance to beef calves post-weaning. Studies have shown that providing creep feed to calves during the pre-weaning period can improve their nutritional status, which can better prepare them for the …

Characterisation of physiological and immune-related biomarkers of weaning stress in beef cattle
Weaning is a necessary husbandry practice in which nutritional, social, physical and psychological stressors are imposed on the beef calf causing alterations in behavioural and physiological responses. To date, few studies have examined the effect of weaning on the extended physiological and …

The effects of weaning stress on the serum protein profile of calves : a proteomic analysis
… and humans link both physical and psychological stress with an increased rate and severity of infections and onset of diseases. Stress is a very broad and complex topic. It can be defined as a condition occurring in response to adverse external influences capable of affecting physical health …

A pilot study on the effects of sow management practices on piglet immune responsiveness to weaning stress
The consequences of maternal prenatal stress exposure of the gestating sow on the developing immune system of her offspring is not well understood. There is limited data that primarily focuses on the health and well-being of the neonates of livestock animals, principally within the swine industry, …

Increases in Cortisol due to Weaning Stress and the Subsequent Alterations to Immune Function in Beef Calves
Weaning is defined as the physical separation of the cow-calf pair and the end of milk feeding. Natural weaning occurs between 7 and 14 months and is a gradual process. However, domestic weaning occurs between 6 and 8 months and occurs rapidly. Calves that are abruptly separated from their dam …

Examination of the effect of weaning stress on the physiological and molecular regulation of immune function in circulating bovine leukocytes
Weaning is a multifaceted stressor and may involve numerous husbandry practices, including the abrupt separation of the calf from its dam, a nutritional adjustment to a non-milk diet and social reorganisation and, additionally, is often associated with other husbandry practices, such as housing and …

The effects of a yeast probiotic, saccharomyces cerevisiae boulardii, on common sow stressors and their effect on maternal-fetal programming
… health related issue. Maternal stress during late gestation may impair the development and reactivity of the sow’s offspring which impacts disease susceptibility and mortality (Chu et al., 2016). The European-wide ban on antibiotics as growth promoters initially has had …

Pre-weaning diet and stall weaning method influences on stress response in foals
The response of foals to the stress of weaning was examined in terms of a behavioral protocol and the responses of plasma ascorbate, serun1 cortisol, and the serum cortisol response to an ACTH challenge. Behavior scores (1 to 10) as an index of stress were assigned to each foal daily, with high …

The effect of supplementation strategy, stress level, and tall fescue type on performance of fall-weaned beef calves
The beef cattle marketing structure imposes stress on calves due to weaning, transport, commingling, and adaptation to new diets, resulting in a weakened immune systems at the height of disease risk, frequently causing bovine respiratory disease. Backgrounding programs facilitate opportunities for …

Bioinformatics characterization of the molecular pathways impacted by immune challenges in the amygdala
… role in fetal development, and environmental stressors and pathogens that elicit an immune response in the mother have the ability to influence critical processes within the fetus during development. This maternal immune activation (MIA) can have lasting effects on the fetus and has been …

A pilot study on the effects of a yeast probiotic on sow and piglet behavior and well-being
… well-being, and (b) assess the effects of weaning stress on piglets from sows that were fed probiotics. At d 84 of gestation, 18 sows derived from Genetiporc maternal line across 3 blocks (6 sows/block) were randomly allotted to receive either a placebo bolus (control; CON) or probiotic …

Evaluation of By-product Feedstuffs, Level of Concentrate, and Selenium and Vitamin E Injections on Performance and Health of Beef Calves in Backgrounding Systems
Weaning stress in young calves is often compounded with stress from transport, marketing, and commingling. The result is a weakened immune system, which can lead to increased incidence of diseases, especially bovine respiratory disease complex (BRDC). Backgrounding cattle post-weaning and prior to …
