Subacute rumen acidosis (SARA) is a common dairy herd health issue. Variation among cows in the severity of SARA is a chance to understand the etiology of SARA and prevent the disease. The aim of this study was to determine the relationship between the severities of SARA in the first lactation with that in the second lactation in terms of reticular pH metrics, microbiota and systemic health.

Fumaric acid can be supplemented in the ruminants’ diets without compromising DMI. However, reductions in methane production and yield were observed only in small ruminant (sheep and goats), whoever FA supplementation appears to be less effective in mitigating methane emissions in cattle.

The gut microbiome, which is made up of bacteria, viruses, and fungi, plays a crucial role in the development of a newborn’s digestive and immune systems. The composition of this microbiome is influenced by several factors, including the diet of the mother. This study focused on how supplementing the diet of lactating sows with a specific amino acid, i.e. arginine (Arg), can affect the growth and health of piglets, as well as their gut microbiome.

Feed-grade medications have been widely used in swine production due to their ability to treat a diagnosed pathogen challenge, regulate gut microbiota, promote growth, enhance feed efficiency, and reduce inflammation. Due to concerns of bacterial resistance, some feed-grade medications have been restricted as a growth promotor in some countries.

Weanling pigs are highly susceptible to intestinal health challenges caused by harmful bacterial agents, which can trigger inflammation and weaken intestinal epithelial integrity. However, research on the potential benefits of dietary spirulina as a bioactive feed additive for improving gut health in weanling pigs remains limited.

Numerical abilities play a fundamental role in survival by enabling animals to assess resources and make adaptive decisions. Among these, numerical discrimination, the capability to distinguish between larger and smaller numerosities, is highly studied. Numerical discrimination can be solved using two strategies: the absolute, selecting a specific numerosity, or the relative, identifying the larger or smaller one.

Pregnancy loss (PL) is a major contributor to reproductive inefficiency in beef cattle operations and carries significant economic implications for producers. Although management and environmental factors are known to influence pregnancy maintenance, the genetic factors contributing to PL remain poorly understood, particularly in Bos indicus-influenced breeds.

This study examined the effects of supplementing rumen-protected methionine (RP-Met) during the periconceptional period on post-weaning traits of female offspring. A total of 114 beef cows were randomly assigned to a control (CON; no RP-Met) and RP-Met treatment.

Recent advances in animal breeding and genetics have made it possible to combine records, genotypes, and pedigree into a single input for predicting breeding values, making genomic evaluations easier and more efficient. However, large genomic models remain computationally expensive.

This study investigated the impact of Methylococcus capsulatus, mixed with or without purified bacterial strains or mixed rumen fluid, on feeding grass-based and/or grain-based diet rations, as well as changes in bacterial cells, rumen fermentation rates, gas production, and rumen microbiota in in vitro and continuous culture. Three experiments were carried out using in vitro ANKUM gas production systems (Exp. 1 and 2) and continuous recirculating flux chamber systems (Exp. 3).

This study evaluated the effects of incorporating spray-dried porcine plasma (SDP) into extruded dog diets. Spray-dried plasma is a functional protein ingredient rich in bioactive compounds that may support digestion, gut health, and immune function.

The utilization of traditional soybean meal in pet food has been limited by its low methionine content and flatulence-causing oligosaccharides. Microbially enhanced soybean protein and Aspergillus oryzae fermented soybean meal (F-SBM) are bioprocessed soybean meal products with potentially improved nutritional value.

Acute ruminal acidosis (ARA) is a detrimental metabolic digestive disorder in ruminants, triggered by sudden intake of high-concentrate diets such as corn and wheat flour. This condition leads to a sharp drop in rumen pH and excessive accumulation of fermentation products like L-lactic acid, D-lactic acid, and lipopolysaccharides (LPS), which can enter the bloodstream.

Congress remains at an impasse regarding reopening the federal government. The House of Representatives passed a continuing resolution that would keep the government funded through November 21st. Since that time, the Senate has failed to pass the continuing resolution, failing on largely party line votes each time it has been considered.

Human beings have interacted with flora and fauna in their shared environment throughout history. These relationships—necessary for food, shelter, and companionship—reflect a deep connection with both living and nonliving elements in our world. Societal progress, however, has altered our interactions with animals, plants, and the environment.

For centuries, native and indigenous populations around the globe interacted with their surroundings as part of their daily live routines to hunt and harvest for nourishment, to celebrate, and to survive. They understood that their actions had major consequences on crops, animals, rivers, and forests.

Animal science is the study of the biology, care, and management of animals, focusing on their health, behavior, nutrition, physiology, and breeding. Animal science has a critical role in One Health, which emphasizes the interconnectedness of human, animal, plant, and environmental health. In this context, animal science helps ensure the well-being of livestock, pets, and wildlife, the maintenance of a safe food supply, and the reduction of zoonotic disease outbreaks, while contributing to environmental sustainability.

In 2023, approximately 48.6 million children aged 0 to 14 lived in Ethiopia (UNICEF Ethiopia Annual Report, 2023). While Ethiopia produces about 12 billion liters of milk annually (Ministry of Agriculture, 2025), this is insufficient to meet the World Health Organization’s (WHO’s) recommendation of 200 kg dairy per person per year, requiring over 9.7 billion liters annually just for children. The current intake is only 11% of this target (Farrell, 2021).

The concept of One Health may be associated with many diverse interpretations in both scope and practice as viewed from a particular frame of reference or perspective. From a general perspective of human and veterinary medicine, One Health is based on the general premise that human and veterinary medicine are connected at multiple levels, with environmental and socioeconomic factors often providing a common denominator.

Saccharomyces cerevisiae fermentation-derived postbiotic (SCFP) has been shown to increase ruminal pH of cattle fed a high-concentrate diet. Increased ruminal pH has been linked to increased methane emissions. Some studies have suggested that SCFP can reduce methane emissions by improving feed efficiency.
