Milk is an important food source, consisting of a complex mixture of lipids, proteins, carbohydrates, and other factors, of which milk fat not only affects the flavor and nutritional value of milk but also plays an important role in the metabolism of nutrients during human growth and development.

We estimated genetic and phenotypic correlations and heritabilities for temperament indicators in growing pigs such as fearfulness (i.e., vocal and physical withdrawal response to an approaching human while isolated in an arena; attempts to escape from a weigh crate); boldness (i.e., biting, following or nosing a human walking inside their home pen) and aggression (i.e., skin lesions). Our results indicate that the studied traits were heritable, and some of these traits could potentially be useful for genetic selection.

In this study, we investigated the antioxidant effect of monoammonium glycyrrhizinate (MAG) on calf intestinal epithelial cells (CIECs) exposed to heat stress in vitro. Calves are sensitive to heat stress, and high temperatures can stimulate heat stress and produce a large number of reactive oxygen species (ROS) to induce oxidative stress.

In 1991, researchers in animal and plant sciences met at the International Symposium on Forage Cell Wall Structure and Digestibility in Madison, WI (Front Matter, 1993). At that meeting, seven sessions were organized, representing some of the biggest names in forages and ruminant nutrition, to discuss and debate the cell wall, its role in ruminant nutrition, and the advances made in the science of forage nutrition.

Forage degradation in the rumen is critical to producing ruminant animals. For many years, scientists were limited to biochemical techniques to understand how ruminal microbes degraded forage, impairing our understanding of which microbes were involved with degrading which forage components.

Mineral requirements for feedlot cattle are largely based on measured mineral concentration in the body at harvest. Fairly extensive research has been done quantifying Ca and P in the body of cattle, but data on Mg, K, and S are sparse. Serial harvest experiments are expensive and labor intensive and therefore not conducted frequently. A group of 115 Holstein steers was fed a finishing diet with serial harvest every 28 d.

Starch digestibility varies greatly depending on starch source (SS), grain processing, and potentially interactions between these factors. Four ruminally cannulated lactating Holstein cows were fed a total mixed ration that varied in SS and particle sizes (PS) to evaluate the interactions between SS and PS on ruminal fermentation, nutrient flow, starch digestibility, and lactation performance of dairy cows.

Ochratoxin A (OTA) is a potent toxin frequently present in animal feeds, which accumulates in the animal tissues for human consumption. This results in critical animal welfare issues, as well as food safety issues. To the best of our knowledge, the present study is the first to show that OTA can be degraded by an enzyme supplemented with pigs’ feed.

The scale of the global pet food market is expanding daily, but there are relatively few evaluations that have been performed on many of the common ingredients in pet food recently. This study compares direct, difference, and regression methods of evaluating the effects of the energy values of poultry byproduct meal (PBM), which is commonly used in beagle foods.

Here, we report for the first time the molecular mechanisms of testicular regression in mink. Our results, together with studies on other animals’ characteristic reproductive features, identify a cluster of events crucial to the seminiferous epithelium regression process in mammalian seasonal breeders and highlight perspectives unique to the mink.

The United States Trade Representative Katherine Tai has requested dispute settlement consultations with Mexico under the United States-Mexico-Canada Agreement (USMCA). These consultations regard certain Mexican measures concerning products of agricultural biotechnology.

In response to the Supreme Court’s decision on California Proposition 12 (Prop 12), The Ending Agricultural Trade Suppression (EATS) Act was introduced to prevent states like California from regulating farmers and ranchers nationwide.

Texas Governor Greg Abbott recently signed a bill into law that will require labels for meat alternatives and lab-grown meat sold in the state. The law directs plant-based and other alternative products to have clarifying verbiage appear next to the label with similar size text as the product being sold.

The United States Supreme Court recently published a ruling on Sackett v. Environmental Protection Agency, involving the “Waters of the United States” (WOTUS) under the Biden Administration’s revised Clean Water Act. The ruling limits the authority of the Environmental Protection Agency (EPA) in regulating certain bodies of water that qualify as WOTUS. This is a huge win for farmers and landowners.

A new preprint article from researchers at The University of California, Davis (UC Davis) has found that lab-grown meat’s environmental impact is likely to be higher than retail beef based on current and near-term production methods. Lab-grown meat is growing in popularity. It is cultured from animal cells and is often thought to be more environmentally friendly than beef due to the need for less land, water, and greenhouse gases compared to raising cattle.

The Safeguarding American Value-Added Exports Act (SAVE Act) was recently introduced in the House and Senate, to protect American food products from foreign trade practices.

A new bill introduced by Senators John Hickenlooper (D-CO), Deb Fischer (R-NE), Amy Klobuchar (D-MN), Todd Young (R-IN), Tammy Baldwin (D-WI), and Roger Wicker (R-MS) would fund community college workforce training, education, and research programs in agriculture.

The North American Meat Institute (Meat Institute) recently announced the launch of the Protein PACT Academic Advisory Council. The advisory council was formed to advise on research priorities and the latest evidence related to meat production and consumption.

House Ag Committee Chair Glenn “GT” Thompson (R-PA) and Ranking Member David Scott (D-GA) recently sent an open letter to 18 state governors calling for increased funding for 1890 Land-Grand Institutions. The 1890 land-grant institutions are historically black universities that were established under the Second Morrill Act of 1890. The United States of Agriculture’s (USDA’s) National Institute of Food and Agriculture’s (NIFA's) 1890 land-grant institutions programs are intended to strengthen research, extension, and teaching in the food and agricultural sciences by building the institutional capacities of the 1890 Institutions.

The United States Department of Agriculture (USDA) has set August 23, 2023, as the date for the hearing to revise the Federal Milk Marketing Order (FMMO) system. If all goes to plan, an updated FMMO system could be actively benefiting farmers in late 2024.
