    Interpretive Summary: Some of the Endangered Species Act’s listings will soon be modified


    Two resolutions to nullify the Biden Administration’s Endangered Species Act listings have passed the Senate and the House of Representatives and will now go to the President’s desk for signature. The two listings would nullify the lesser prairie chicken listing and the northern long-eared bat listing. Matters of the Endangered Species Act are typically left to the United States Fish and Wildlife Service and the National Marine Fisheries Service, to decide which animals and plants to list as endangered or threatened and how to rebuild their populations.

    Interpretive Summary: The effects of stocking density on behavior and biological functioning of penned sheep under continuous heat load conditions


    There is a high demand for Australian sheep to be exported to the Middle East, and for live export voyages which depart during an Australian winter, heat, and humidity increase rapidly as ships cross the equator and approach destination countries. Concern about sheep becoming heat stressed during these voyages has increased, and industry attention has focused on the potential role of stocking density in determining heat stress risk in this context.

    Interpretive Summary: Methane emissions and 13C composition from beef steers consuming binary C3–C4 diets


    Investigating methods for reducing enteric methane emissions from ruminant livestock are important to reduce environmental impacts and improving production efficiency through reduced energy losses. This experiment evaluated the effects of increasing proportion of rhizoma peanut hay (a C3 legume) into bahiagrass hay (a C4 grass) on intake and methane production in beef steers.

    Interpretive Summary: Duration of ergovaline exposure influences serotonin-mediated vasoactivity of bovine mesenteric vasculature


    Consumption of ergot alkaloids found in endophyte-infected tall fescue can lead to symptoms of fescue toxicosis, such as vasoconstriction, in ruminant livestock species. Ergovaline is one of the primary ergot alkaloids responsible for causing vasoconstriction when toxic varieties of fescue are consumed.

    Interpretive Summary: Endocrine changes during the peripartal period related to colostrogenesis in mammalian species


    This manuscript reviews and compares hormonal and functional changes occurring in the conceptus (embryo and its extra-embryonic membranes) and their effects on the mammary gland during development from pregnancy to colostrum formation and milk production in multiple mammalian species. Declining activity of gestagens at the end of pregnancy is crucial to allow for both parturition and onset of milk production in most mammals.

    Interpretive Summary: Forages and Pastures Symposium: revisiting mechanisms, methods, and models for altering forage cell wall utilization for ruminants


    The underlying principles of forage cell wall utilization by ruminants have been known for over 50 years, but a significant amount of knowledge of the structure and synthesis of critical components of the plant cell wall, mechanisms and methods to alter its digestibility, and assessment techniques to quantify its components as well as their fermentability has been accumulated in the last 30 years.

    Interpretive Summary: Relationships between body- and udder-related type traits with somatic cell counts and potential use for an early selection method for water buffaloes (Bubalus bubalis)


    Some type traits (TTs) have been reported to affect somatic cell count (SCC) in bovine milk, which result in mastitis to some extent, but the correlation between SCC and TTs of water buffalo has been poorly understood. Here, a total of 1908 records from 678 buffaloes were investigated.

    Interpretive Summary: Transcriptomic analysis of ovarian follicles uncovers the crucial genes relevant to follicle selection and preovulatory hierarchy in hens


    Chicken ovarian follicle development undergoes follicle recruitment, prehierarchy, follicle selection, preovulatory/hierarchy, and finally ovulation. The follicle selection and preovulatory hierarchy play a vital role in egg production of hens. However, underlying the mechanism of the key genes involved in these developmental events remains largely unknown.

    Interpretive Summary: Protective effects of genistein on the production performance and lipid metabolism disorders in laying hens with fatty liver hemorrhagic syndrome by activation of the GPER–AMPK signaling pathways


    Fatty liver hemorrhagic syndrome (FLHS) is a nutritional and metabolic disease that seriously threatens the health and performance of laying hens, which is characterized by hepatic steatosis and lipid metabolism disorders. As an isoflavone phytoestrogen, genistein (GEN) exerts many beneficial functions, including alleviating lipid metabolism disorders and anti-inflammatory properties.
