High-moisture corn (HMC) short-term fermentation is affected by dry matter (DM) concentration. Thus, producers try to influence HMC fermentation by using microbial inoculants and by harvesting HMC at different DM concentrations. This study aimed to evaluate the effects of different DM concentrations, heterofermentative microbial inoculants, and storage length on the fermentation and nutritive value of HMC.

Developmental programming has highlighted important influences of maternal factors on offspring development. Recent research indicates a programming potential of the rumen microbiome and understanding this role as well as how inoculation occurs may allow beef producers to optimize management practices of gestating cows such that offspring performance is improved via the rumen microbiome.

Beef cattle production in the southeastern United States is plagued by two common nutritional problems. Fescue toxicosis, caused by consumption of toxic ergot alkaloids in endophyte-infected tall fescue, is a major detriment to growth performance of grazing cattle and profitability for cow/calf and backgrounding cattle operations.

Digital dermatitis (DD) impacts cattle health, productivity, and welfare; and is an emerging challenge for the beef industry. The most obvious clinical sign associated with DD is lameness; however, not all cattle afflicted with DD will become lame.

As a traditional herb, Eucommia ulmoides (E. ulmoides) has been utilized in East Asia for at least 2 000 years. In recent years, E. ulmoides has been applied in the culture of fish for its functions of promoting growth, lipid metabolism, and flesh quality.

The objectives of this study were to 1) assess inclusion of Sweet Bran in diets of feedlot steers on performance and feeding behavior and 2) examine the effects of sorting animals at terminal implant on performance, feeding behavior, and liver abscess occurrence.

In vitro methodologies have been used in animal nutrition research for decades to decrease the use of animals and experimental time and cost. Due to its lower cost, in vitro methodologies are commonly used for preliminary testing, prior to large in vivo trials.

Here we review circadian clocks and their function in the regulation of metabolic and reproductive systems as well as the consequence of circadian disruption on mammary development and lactation with a particular focus on recent research findings from studies of dairy cows.

Traditionally, a 1-yr calving interval is advised to dairy farmers to realize a yearly peak in milk yield. A 1-yr calving interval, however, implies a yearly event of drying-off, calving, and start of lactation, which are all associated with an increased risk for diseases and disorders.

Late-gestation in utero heat stress in dairy cattle negatively affects the mammary microstructure and milk yield at maturity, but investigation into early-life windows of mammary development is needed to fully characterize the lifelong consequences of intrauterine heat stress on the mammary gland (MG).

This month’s feature collection showcases three Board Invited Reviews exploring the biology of lactation from three different perspectives. These include the impact of circadian rhythms on production efficiency, the impact of early heat stress on future cow performance, and a holistic look at how extending lactation length impacts the dairy cow’s whole production cycle and management.

The beef cow utilizes about 74% of total feed energy required to produce beef. Therefore, a more thorough understanding of feed intake, weight gain, and feed efficiency traits in the beef cow is fundamental to reducing cost and improving the environmental footprint of beef production.

Methionine supplementation can improve immune function in transition dairy cattle. Our objective was to determine if supplemental methionine could improve health and performance of newly received growing cattle.

Reducing dietary crude protein (CP) content reduces nitrogen excretion to the environment and undigested protein availability to enteric pathogens in the hind gut resulting in reduced postweaning diarrhea and improved gut health. To meet the amino acid requirements in low CP diets, supplementation of essential amino acids in nursery diets is necessary, and the availability of more feed-grade crystalline amino acids allows low CP diets to be practically formulated.

This study tested the effects of a mildly cooked human-grade diet and a feed-grade extruded kibble diet on the fecal microbiome, skin and coat health measures, and expression of genes related to inflammation and oxidative stress in healthy adult dogs.

Feeding pigs supplemental fat to increase caloric density is a common practice in the swine industry. However, dietary fats are also a key determinant of pork fat composition and may influence product quality.

Dry-corn milling biorefineries have the opportunity to install technology to fractionate corn prior to fermentation, which creates a product stream of fibrous bran that can be fed to cattle. The objective of this study was to determine the effects of replacing dietary corn with corn bran and condensed distillers solubles (CBCDS) or wet-corn gluten feed (WCGF) on growth performance, efficiency of dietary net energy (NE) utilization, and carcass characteristics in finishing steers.

The United States White House announced for the first time in more than 50 years, that it will hold a conference on hunger, nutrition, and health. The conference is set to be held on September 28, 2022, along with the publication of a National Strategy containing actions the federal government will take to drive solutions to these challenges.

The United States Department of Agriculture (USDA) has announced it will invest $121 million in infrastructure to combat climate change in rural parts of America. Over 280 projects throughout 49 states, Guam, and Puerto Rico will be funded.

During a Zoom call, the United States Department of Agriculture (USDA) announced $400 million in funding to create USDA Regional Food Business Centers. The Regional Food Business Centers will provide coordination, technical assistance, and capacity building to help farmers, ranchers, and other food businesses access new markets and navigate federal, state, and local resources.
