Tryptophan is often a limiting amino acid in corn-soybean meal-based diets of pigs and plays a vital role in appetite regulation. However, this mechanism competes with other large neutral AA such as Val, Leu Ile, Tyr, and Phe. Standard corn and sorghum diets fed to pigs are rich in Leu and may reduce pig feed intake and growth performance.

Drylots are becoming a more common method of managing cow/calf pairs because they provide more flexibility for nutritional management, calving monitoring and provide shelter from wind and rain to decrease maintenance nutrition requirements in the winter. However, limited work has focused on the impact of dry-lot cow/calf management on cow/calf behavior and performance around the time of weaning.

Managing low protein diets in pigs is challenging because reduced dietary protein frequently leads to impaired growth performance and increased intramuscular fat. Supplementation with essential amino acids (particularly lysine, tryptophan, threonine, and methionine) is helpful, however may not fully ameliorate the negative impacts of a low protein diet.

Longer reproductive lives are highly sought after in sows because it increases the profitability of commercial farms. Sows that reach their fourth parity and produce large litters are highly desired.

Intrauterine growth restriction (IUGR) caused by placental insufficiency is highly problematic because fetal hypoxemia leads to low birthweight and impaired growth in livestock. Ways to counter the negative impacts of placental insufficiency are therefore necessary to increase the productivity and health of IUGR-born livestock.

Silymarin is a flavonolignan extracted from milk thistle fruit and seeds. It has traditionally been used to reduce liver inflammation and toxicity in both humans and animals but may also potentially increase milk production during lactation.

Dietary spray-dried plasma protein (SDPP) is widely used in nursery pig diet due to its high nutrient contents and growth-promoting effects. In the present work, two sources of SDPP were evaluated for energy and amino acid (AA) digestibility and growth performance in nursery pigs.

Promising research is being performed at the Institute for Global Food Security (IGFS) at Queen’s University Belfast, feeding seaweed to farm animals. The technique is said to reduce methane by at least 30%.

NCBA agrees that the labeling of these products is important. Danielle Beck, Senior Executive Director of Government Affairs, noted a survey where 74% of consumers agreed that there should be a clear indication of whether the meat, they are purchasing is either lab-grown or conventionally produced.

The Food and Agriculture Organization of the United Nations (FAO) recently published The State of Food and Agriculture 2021. The report comes after the COVID-19 pandemic showed vulnerability within the agrifood system globally.

The United States Environmental Protection Agency (EPA) has published From Farm to Kitchen: The Environmental Impacts of U.S. Food Waste, to inform policymakers, researchers, and the public about the environmental impact of food waste. The report includes benefits to reduced food waste as well as knowledge gaps.

The bill is designed to direct the United States Department of Agriculture (USDA) to initiate the process of holding Federal Milk Marketing Order (FMMO) hearings within six months to provide an opportunity for producers to have a seat at the table when any potential changes in how Class I milk prices are calculated is discussed.

“The federal government has shown, time and time again, that when it’s given the resources needed to accomplish the impossible, there’s not much it cannot do,” DeGette and Upton said in a press release. By creating ARPA-H, we will be bringing together some our nation’s greatest minds to help find cures to these devastating diseases.

A bipartisan letter from more than 70 members of Congress was sent to President Joe Biden regarding the United States-Mexico-Canada Agreement (USMCA). The letter urges President Biden to pursue a declaration from Mexican President López Obrador that Mexico will follow the biotech provisions established in USMCA.

During the height of the pandemic, it was revealed that over 59,000 meatpacking and processing workers contracted COVID-19, and at least 269 died. PAMWA would provide protections for meatpacking workers along with systemic reforms, such as creating a fair market that allows independent farmers, ranchers, and local food systems to succeed.

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has issued a final rule modifying the Animal Welfare Act (AWA) regulations to include a requirement for a contingency plan for the handling of animals during an emergency.

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) recently announced over $16.3 million to 64 different projects with states, universities, and other partners for animal health protection.

The estimated breeding value (EBV) of an animal measures its genetic merit. For calculating EBVs, pedigree and genomic information are jointly used in a procedure called single-step genomic best linear unbiased prediction (ssGBLUP). Genetic evaluations report each EBV with its reliability, which measures how accurate the breeding value estimation was.

Current research examined Lycium barbarum polysaccharides (LBP) for combating LPS-induced inflammatory responses in primary bovine mammary epithelial cells. We uncovered a preventive role of LBP in reducing detrimental effects induced by LPS including inhibition of NF-κB and MAPK along with peroxisome proliferator-activated receptor-γ (PPARγ) activation.

A major goal in animal agriculture is to improve the nutritional value of animal products. One area of focus in the beef cattle industry is to use supplemental selenium to improve the antioxidant abilities of muscle and liver tissue, which may reduce the cholesterol levels of muscle tissue, resulting in a healthier product.
