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.

United States Senators Tammy Baldwin (D-WI) and Chuck Grassley (R-IA) introduced a new bill, designed to increase the transparency and oversight of foreign ownership in America’s agricultural industry. The Farmland Security Act of 2023 builds on the Farmland Security Act of 2022, by ensuring that all foreign investors who buy American agricultural land report their holdings and strengthens the penalties for those who evade the required filing.

Through the Agriculture Resilience Initiative (AGRI)- Ukraine, the United States announced it will provide $250 million in aid to Ukrainian agriculture producers and farmers. AGRI- Ukraine is an initiative started last year to support Ukrainian agriculture exports and combat global food security issues exacerbated by the Russian invasion.

The United States Department of Agriculture (USDA) has announced a partnership with attorney generals in 31 states and the District of Columbia to enhance competition and protect consumers in food and agricultural markets, including in grocery, meat, and poultry processing, and other markets. The partnership will assist state attorneys general in tackling anticompetitive market structures in agriculture and related industries that are raising prices and limiting choices for consumers and producers.

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.

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.

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.

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.

Current studies are aimed towards utilizing certain lactic acid bacteria (LAB) strains with high-yielding beneficial organic acid production for enhancing the quality of forages during preservation (otherwise known as ensiling) and to improve animal feed production.

Due to its extensive biological functions, melatonin has been widely used in animal production in recent years. The purpose of this study was to investigate the effects of melatonin on growth performance, muscle development, and lipid metabolism of weaned piglets.

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.

Zinc oxide and copper sulfate are commonly used as growth promoters and alternatives to antibiotics to prevent diarrhea in weaned piglets but their use in post-weaning pigs diets has been challenged due to environmental issues and concerns related to bacterial resistance to antibiotics and heavy metals.

Ocimum gratissimum (OG) was found to have immunity boosting effect on Taiwan country chickens and broiler chickens raised in moderate ambient temperature in previous studies, and the current study investigates its potential on broilers raised in high ambient temperature.

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.

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.

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.

Efficiently producing cattle to feed a growing population can come with many challenges. A few challenges occur soon after a cow has given birth, and subsequent reproductive performance can be impacted. Bacteria within the reproductive tract can trigger an immune response and together play a role in affecting fertility in cows.

Feedlot growth performance and carcass data can be used to estimate dietary net energy values. The degree to which growth performance-predicted values agree with tabular energy values for feeds is an indication of how accurately the California Net Energy System can be used to predict cattle growth performance.

Bovine respiratory disease (BRD) remains the leading cause of feedlot calf sickness and death. In respiratory disease affecting humans and mice, major tissue damage is caused by release of histones. Histones are proteins found in the nucleus of cells that condense DNA, however, cells that become damaged release histones extracellularly.

Precision technologies are revolutionizing animal agriculture by enhancing the management of animal welfare and productivity. To fully realize the potential benefits of precision livestock farming (PLF), the development and application of digital technologies are needed to facilitate the responsible and sustainable intensification of livestock production over the next several decades.
