Material composition and mechanical properties of the venom-injecting forcipules in centipedes Front. Zool. (IF 2.6) Pub Date : 2024-08-23 Simon Züger, Wencke Krings, Stanislav N. Gorb, Thies H. Büscher, Andy Sombke
Centipedes are terrestrial and predatory arthropods that possess an evolutionary transformed pair of appendages used for venom injection—the forcipules. Many arthropods incorporate reinforcing elements into the cuticle of their piercing or biting structures to enhance hardness, elasticity or resistance to wear and structural failure. Given their frequent exposure to high mechanical stress, we hypothesise

Caffeic acid modulates intestinal microbiota, alleviates inflammatory response, and enhances barrier function in a piglet model challenged with lipopolysaccharide J. Anim. Sci. (IF 2.7) Pub Date : 2024-08-19 Xiaobin Wen, Fan Wan, You Wu, Yueping Liu, Ruqing Zhong, Liang Chen, Hongfu Zhang
Young animals are highly susceptible to intestinal damage due to incomplete intestinal development, making them vulnerable to external stimuli. Weaning stress in piglets, for instance, disrupts the balance of intestinal microbiota and metabolism, triggering intestinal inflammation and resulting in gut damage. Caffeic acid (CA), a plant polyphenol, can potentially improve intestinal health. Here, we

Glucose inhibits the inflammatory response in goose fatty liver by increasing the ubiquitination level of PKA J. Anim. Sci. (IF 2.7) Pub Date : 2024-08-19 Mengqing Lv, Ji'an Mu, Ya Xing, Xiaoyi Zhou, Jing Ge, Daoqing Gong, Tuoyu Geng, Minmeng Zhao
Protein kinase A (PKA) plays an important role in cellular life activities. Recently, PKA was found to bind to inhibitor of nuclear factor-kappaB (IκB), a key protein in the nuclear factor-kappaB (NF-κB) pathway, to form a complex involved in the regulation of inflammatory response. However, the role of PKA in the anti-inflammatory of goose fatty liver is still unclear. A total of 14 healthy 70-day-old

The Dodo and its extinct sister species, the Solitaire, are iconic exemplars of the destructive capabilities of humanity. These secondarily terrestrial columbids became extinct within a century of their first encounter with humanity. Their rapid extinction, with little material retained in natural history collections, led 18th and some early 19th century naturalists to believe that these aberrant birds

Lipolysis pathways modulate lipid mediator release and endocannabinoid system signaling in dairy cows’ adipocytes J. Anim. Sci. Biotechnol. (IF 6.3) Pub Date : 2024-08-03 Madison N. Myers, Miguel Chirivi, Jeff C. Gandy, Joseph Tam, Maya Zachut, G. Andres Contreras
As cows transition from pregnancy to lactation, free fatty acids (FFA) are mobilized from adipose tissues (AT) through lipolysis to counter energy deficits. In clinically healthy cows, lipolysis intensity is reduced throughout lactation; however, if FFA release exceeds tissue demands or the liver’s metabolic capacity, lipid byproducts accumulate, increasing cows’ risk of metabolic and infectious disease

Effects of perinatal exposure to daily maximum THI and THI fluctuations on serum total proteins and health of preweaned Holstein heifers raised in a dry climate J. Anim. Sci. (IF 2.7) Pub Date : 2024-07-29 Diego Manriquez, Afrin Jannat, Ana Velásquez-Munoz, Pablo Pinedo
The objective of this study was to assess the effects of the exposure to daily maximum and temperature-humidity index (THI) and to daily THI fluctuations (∆THI = maximum THI – minimum THI) at exposure periods comprising 2 d before birth to birth (-2 d), birth date (0 d), birth to 2 d of age (+2 d), and birth to 7 d of age (+7 d) on serum total proteins (STP), transfer of passive immunity (TPI), and

Estimating body composition using CT scans of cross-bred lambs fed at two feeding levels and two stages of maturity to inform predictive growth models1 J. Anim. Sci. (IF 2.7) Pub Date : 2024-07-29 Thomas P Keogh, Shawn R McGrath, Maxwell B Allworth, Victor H Oddy
Livestock producers would benefit from more precise predictions of the growth response from nutrients consumed. Previously published models are often limited by the realities of data collection and are unable to account for alterations to body composition, due in part to the response of visceral organs to an alternate diet. The computerized tomography (CT) scanning of lambs enables the analysis of

Examining the Long-Term Impacts of Ergot Alkaloids on Fetal Heifer Development and Subsequent Growth and Reproductive Performance J. Anim. Sci. (IF 2.7) Pub Date : 2024-07-29 M L J Haimon, R K Poole, M A Newsome, A R Brown, H Dudley, D H Poole
Consumption of toxic endophyte-infected tall fescue results in poor reproductive performance in domestic livestock. In this study, the objective was to evaluate the effects of ergovaline exposure during mid-gestation (days 93 through 188 of gestation) on dam performance, the growing female fetus, and the subsequent growth and reproductive performance of the gestationally-exposed heifer calves. Pregnant
