Large-scale genotyping platforms are valuable tools for animal selection and breeding programs. The bead chip has been widely used in both research and commercial applications for a long time. A highly efficient and economical genotyping platform has been developed recently.

Cold climates can affect cattle performance, survival, and health. Local cattle breeds have been adapted to the local environments including extremely cold temperatures after a long period of natural and artificial selection.

Supplemental fat has been provided to feedlot cattle to increase energy density of their diets, and may yield nutraceutical advantages if includes polyunsaturated fatty acids (FA). Alternatively, carcass quality can be improved when the fat supplement is based on saturated and monounsaturated FA.

Increased atmospheric CO2, rising temperatures, and altered patterns of precipitation can limit the production of certain crops commonly used in agriculture, increasing risk, cost, and availability of feedstuffs. The search for alternative plants that could thrive in these changing scenarios is necessary to provide producers with a broader array of options to feed cattle.

The composition and physical properties of milk fat affect the quality and sensory properties of dairy products. However, changes in the physical properties of milk fat globules (MFGs) and profiles of milk fatty acids (FAs) of goat milk throughout the lactation period remain unclear.

Traditionally, it has been believed that dairy cows are able to fully utilize the phosphorus (P) in feed, including that from plant-derived phytate, because of phytase activity of bacteria in the rumen. However, recent data have shown otherwise.

Red clover is rich in the bioactive isoflavone, biochanin A. The goal was to evaluate the impacts of biochanin A supplementation via red clover hay on growth performance of ram lambs as well as the rumen microbiota and fermentation.

Individual reproductive capacity is crucial to poultry breeding and reproduction. The hypothalamus–pituitarium–gonad axis is an important pathway regulating animal spermatogenesis and sexual behavior. This study identified the neuroactive ligand–receptor interaction pathway as the potential biological pathway regulating the semen quality and sexual behavior by differential transcriptome analysis of the hypothalamus and pituitarium of male ducks.

Our objective was to test the effects of a novel milk oligosaccharide biosimilar (GNU100) on the fecal characteristics, microbiota, and bile acid (BA) concentrations of healthy adult dogs treated with antibiotics.

Individual experience and demographics affect perceptions of animal production. Understanding how science-based education alters these opinions is a critical aspect of improving instruction and increasing consumer engagement in the poultry industry.

To preserve the semen of male pigs for long-term usage, especially for artificial insemination, semen samples are frozen at temperatures below zero degrees. This research study was conducted with the aim of improving the qualities of semen samples from male pigs that are usually negatively impacted by extremely low temperatures during the preservation process using liquid nitrogen.

The amino acids (AA) in the diet of pigs are usually supplied as a mix of proteins and free AA. Proteins need to be digested first before their constituent AA become available to the animal. Free AA, together with small peptides, are readily available without the need for digestion.

The objective of this study was to characterize developmental differences in low birth weight (LBW) and normal birth weight (NBW) piglets with or without pre-weaning nutrient restriction using serum metabolomic profile analysis. Through the serum metabolite analysis, at weaning, we saw fewer metabolites associated with fatty acid oxidation, and glycolysis in the LBW pigs compared to the NBW.

Milk is essential for healthy growth and development of neonates, with proteins in milk serving as key nutrients and regulators of these processes. Protein activity is affected by modifications made to their structure including the addition of sugar groups called glycans. Here we present the characterization of sow milk proteins modification with glycan groups on asparagine and glutamine amino acids in colostrum, transitional, and mature milk of pigs.

The United States Department of Agriculture Under Secretary for Trade and Foreign Agricultural Affairs Alexis Taylor and Office of the United States Trade Representative Chief Agricultural Negotiator Doug McKalip, met with Mexican officials to discuss the ongoing battle over genetically modified corn.

The United States Department of Agriculture’s (USDA’s) National Agricultural Statistics Service (NASS) has released the latest cattle inventory report. According to the report, cattle inventories totaled 89.27 million head, a 3% decline year over year. This is the smallest herd size for January 1st in 61 years.

The National Chicken Council (NCC) has called for the United States Food and Drug Administration (FDA) to take measures to decrease egg prices. The chicken industry is examining a policy that forces the broiler industry to destroy safe eggs, due to the current outbreak of highly pathogenic avian influenza (HPAI) in the United States.

The United States Environmental Protection Agency (EPA) has released the Effluent Guidelines Program Plan 15 (Plan 15), which lays out how the Agency will work to protect the nation’s waterways by following the science and the Clean Water Act to develop technology-based pollution limits and studies on wastewater discharges from industrial sources. Part of Plan 15 includes a new study on the impact of concentrated animal feeding operations (CAFOs) on water quality.

The Foreign Adversary Risk Management (FARM) Act has recently been introduced in the House and Senate. The FARM Act will amend the Defense Production Act of 1950 to prevent harm and disruption to the United States agriculture industry by protecting against foreign influence over agriculture production and supply chains, and for other purposes.

The United States Department of Agriculture (USDA) has named Simon Liu, Ph.D. as the Administrator of the Agricultural Research Service (ARS). While Liu was officially named as ARS Administrator on January 4, 2023, he has been acting in this role since June 2022. In this role, Liu will lead the agency in its efforts to leverage the latest advances in science and technology and develop innovative solutions to agricultural challenges facing the nation and world.
