Safety and efficacy of a feed additive consisting of an essential oil obtained from the flowering aerial parts of Thymus vulgaris L. and/or Thymus zygis L. (thyme oil) for use in all animal species (FEFANA asbl)

- AbstractFollowing a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of an essential oil from the flowering aerial parts of Thymus...

20?Using anogenital distance, a prenatal marker of androgen exposure, to predict pregnancy by artificial insemination in yearling beef heifers

19/12/2025 - Anogenital distance (AGD), distance from the anus to the clitoris is programmed during fetal life by testosterone concentrations. In rodents, fetal testosterone increases AGD and reduces reproductive...

46?Maternal nutrition and developmental programming – lessons from livestock models

19/12/2025 - Our laboratories study “problems of pregnancy,” which include infertility, poor pregnancy outcomes (often reflected by fetal growth restriction and the accompanying low birthweight), and...

58?Effects of gestational nutrition in an earlier pregnancy on growth of subsequent offspring in grazing beef cattle

19/12/2025 - : IntroductionHuman health effects due to birth order have been extensively studied. This topic is less researched in livestock, likely due to pronounced confounding of birth order with age of dam in...

18?Metabolic manipulation of spermatozoa improves sperm function with implications for Assisted Reproductive Technologies

19/12/2025 - : IntroductionDespite advances in Assisted Reproductive Technologies (ART), obtaining developmentally competent embryos remains a major challenge. We previously demonstrated that modulating sperm...

23?Trainee Award: Vitamin and mineral supplementation in beef heifers and the impacts on intestinal vascularity and proliferation in neonatal calves at 30?hours of age

19/12/2025 - : IntroductionVitamins and minerals support nutrient metabolism, immunity, reproduction, and fetal development in beef cattle, with prenatal supplementation potentially impacting offspring growth,...

64?Late gestation maternal feed restriction alters specific rumen microbiota of the neonatal beef calf

19/12/2025 - : IntroductionFeed restriction during late gestation in beef cattle is a relevant issue in the inter- mountain west due to the overlap of limited and low-quality feed resources with heightened energy...

22?The pre-ruminant microbiome: why do we care and where does it come from?

19/12/2025 - : IntroductionDespite ruminant livestock being born with a non-functional rumen, the early rumen microbiome can have lasting impacts on animal performance. Identifying key sources of colonization of...

Evaluation of dietary inclusion of a blend of essential oils and probiotics for growing beef cattle

25/11/2025 - An experiment was conducted to compare the effects of feeding a proprietary blend of probiotics (Bacillus licheniformis and Bacillus subtilis) mixed with a blend of monoterpene and phenylpropene...

Experiential learning improves college student perceived understanding and strengthens their perceptions of the beef industry

07/11/2025 - Animal science is an applied discipline and post-secondary curriculum must prepare students for matriculation into a dynamic and complex industry. As the backgrounds of students pursuing animal...

Comprehensive farm-level analysis of environmental and management descriptors for developing an efficient genetic evaluation of pasture-raised beef cattle

04/11/2025 - The main objective of this study was to investigate environmental factors affecting yearling weight (YW) in pasture-raised Nellore cattle. The dataset encompassed records from 143,332 animals across...

Year-round supplementation of direct-fed microbials to cow-calf pairs and its effects on maternal and offspring productive performance

04/10/2025 - On day 0 (94?±?19?days prepartum), 296 Brangus beef cows (7?±?3?years of age; <25% Bos indicus) were stratified by body weight (BW; 537?±?56?kg) and body condition score...

Application of DNA parentage testing and EnVigour HX™ to evaluate bull prolificacy and heifer performance in beef cattle breeding programs in Western Canada

23/09/2025 - The use of multi-sire breeding pastures is a common practice in Western Canada for beef cattle management. However, the number of progenies sired by each bull may not be known or producers will not...

Age at first mating and season of dam birth affect reproductive and productive traits of Mozambican Angoni cattle

22/09/2025 - This retrospective observational study aimed to evaluate the effects of age at first mating (AFM) and season of dam birth (SB) on age at first calving (AFC), birth weight of calves (BW), and calving...

Changes in physiological and immunological variables in weaned dairy calves exposed to different stressors
