Feedstuffs contain different carbohydrate fractions that are digested in different parts of the gastrointestinal tract of horses. Grass for grazing or harvesting contains variable amounts of structural carbohydrates such as cellulose and hemi-cellulose (named fibres) and nonstructural carbohydrates which in temperate grass species include sugars and fructans (named water soluble carbohydrates (WSC)).

Ambient temperature may influence the energy requirement of gestating sows, but this factor is not yet integrated daily in the calculation of this requirement. The objective of this study was to quantify the effect of temperatures on sow’s behavior, physical activity, and energy requirements on gestating sows.

This study evaluated the effects of supplementing forage fed cattle with 3-nitrooxypropanol (150 mg/kg dry matter) on feed intake, rumen fermentation and microbial community composition, methane emissions, and nutrient digestibility. Eight ruminally cannulated beef heifers were used for the experiment.

Dry matter intake (DMI) models for beef cattle in the Northern Great Plains may not be a good fit because of extreme weather conditions experienced in this region. The objective of this study is to include additional weather variables (temperature, dewpoint, wind speed, range of temperature, and solar radiation as well as 2-wk lag and monthly lag for each weather variable) that may influence DMI models to improve accuracy.

Excessive intake of rapidly fermentable nutrients by feedlot cattle can result in clinical or subclinical disorders that impair nutrient digestion, while negatively affecting animal development and health. Incidences of subclinical digestive disturbances may increase during the last days on feed in cattle fed in confinement.

A pooled analysis of research was conducted to evaluate the effect of corn processing method, distillers grains type, oil removal from distillers, and distillers inclusion on cattle performance within studies conducted at the University of Nebraska-Lincoln between 1992-2020. Two corn processing methods were included in the dataset, steam-flaked corn (SFC) or any combination of high-moisture (HMC) and dry-rolled corn (DRC), fed with and without distillers gains, a by-product of the dry milling ethanol industry.

The number of dairy steers contributing to the U.S. fed beef supply has increased from 6.9% to 16.3% over the last two decades. Raising dairy cattle breeds for beef production offers unique opportunities and challenges when compared with feeding beef cattle breeds.

The potential for growing systems in beef cattle operations depends on the development of cost-effective alternatives for adding value to cattle after weaning. Alfalfa provides several ecosystem services to beef operations through greater opportunities for manure spreading, longer soil cover, pollinator habitat, and greater carbon sequestration compared to corn silage.

The low intake of feed that beef calves exhibit during the first weeks after feedlot arrival results in inadequate nutrient intake, especially energy, which leads to low rates of gain and decreased immune function and likely increases the risks for respiratory diseases. Increasing the energy density of receiving diets (Mcal/kg of dry matter) could result in increased energy intake of newly received finishing cattle.

The strategic inclusion of one-carbon metabolites, which include vitamins and minerals that are found in human prenatal vitamins, to beef cattle feeding and management protocols during the periconceptual period (the time around breeding) is a novel concept. Therefore, this study aimed to identify the feeding and injection doses of one-carbon metabolites in beef heifers to maintain increased circulating concentrations of one-carbon metabolites for use as a model from which other studies could base their treatments on.

The exposure of pigs to ambient temperature above their comfort zone affects several functions of the small intestine, especially those related with digestion of feed and absorption of nutrients, which in turn reduces the availability of nutrients for growth.

The intensive breeding model of broilers exposes broilers directly to oxidative stress, which is associated with mitochondrial dysfunction. Some researches have shown that bamboo leaf extract (BLE) exhibited antioxidant capacity both in vitro and vivo. However, few researches have been conducted to explore the effects of BLE supplementation on small intestine mitochondrial functions in broilers.

The lactating sow secretes essential fatty acids (EFA) in colostrum and milk to support litter growth and if dietary linoleic (LA) and alpha-linolenic acid (ALA) intake during lactation are limited, subsequent reproductive function of sows may be impaired. However, the inclusion of dietary fat sources with varying EFA composition in lactation diets provided shortly prior to farrowing can increase the energy density of the diet and modify colostrum and milk fatty acid profiles that may influence litter growth performance and survivability.

Goat milk is beneficial for human health because of its nutritional value, especially milk fat, which is plentiful in goat milk. The molecular mechanism of milk fat synthesis is of great importance for developing processing technology and using genetic approaches to improve goat milk quality.

Over the past 115 years, the American Society of Animal Science (ASAS) has evolved into a multi-faceted organization, including establishing the ASAS Foundation 25 years ago as the philanthropic branch of ASAS. The Foundation enhances, advances, and supports ASAS’ mission and initiatives.

The United States Department of Agriculture’s (USDA’s) Economic Research Service (ERS) has published the State Policies for Farm Animal Welfare in Production Practices of U.S. Livestock and Poultry Industries: An Overview report. The ERS report describes the current state of farm animal policies, the extent of their implementation and geographic coverage, and the legal environment and challenges these policies have faced.

A recent survey-based report out of Purdue University's Center for Food Demand Analysis and Sustainability found that in December 2022, household food expenditures have increased by 15% from January 2022. The report assessed food spending, consumer satisfaction, values, support of agricultural and food policies, and trust in information sources.

The Philippine government has extended the lower tariff rates on pork and other food items through 2023, to address supply chain issues and rising inflation. EO No. 171 temporarily reduces the Most Favored Nation tariff rates on pork (fresh, chilled, or frozen), corn, rice, and coal until December 31, 2023, and aims to stabilize the impact of inflationary pressures as a result of the Ukraine-Russia crisis, expand supply sources and reduce the prices of key commodities.

The United States Department of Agriculture (USDA) has announced it will invest $9.5 million in the National Institute of Food and Agriculture’s (NIFA’s) bioproduct pilot program, which will fund three bioproduct manufacturing projects. The program was authorized under the Infrastructure Invest and Jobs Act in November 2021 to give the United States a competitive advantage in the global economy.

The United States Department of Agriculture (USDA) has announced it will invest over $9.5 million to help diversify the nation’s meat supply. The funding comes with the goal of expanding market capacities and market opportunities, particularly in the meat and poultry sectors.
