In the production of laying hens, improving the efficiency of dietary protein utilization is important. The aim of this study was to investigate the effects of the protease DE200 on the performance, egg quality and cecal microflora of Hyline white laying hens.

The impact of calf management and health events have been predominately investigated during the preweaning period. However, calfhood events could also impact the animal’s health and productivity as an adult.

Ganoderma lucidum (GL) is a fungus from which products have become popular in the human food and health industry over the past decade. Due to this, a growing interest in using GL extracts in animal products has also developed.

Some grass species have a symbiotic relationship with an endophytic fungus that produces toxic ergot alkaloids which have detrimental impacts on herbivores. Ergot alkaloids have a significant impact on livestock production causing annual loss to the livestock industry that likely exceeds $1 billion.

The issue of mycotoxin-contaminated animal feed has consistently presented a significant challenge in relation to animal health and production. The mixed-dimensional attapulgite clay (MDA) has been proven effective in binding polar mycotoxins such as aflatoxin, while also effectively adsorbing hydrophobic or weakly polar mycotoxins such as zearalenone (ZEN) and ochratoxin.

Dog foods were produced via extrusion, baking, and pelleting to yield increasing amounts of starch resistant to digestion (resistant starch [RS]). The foods were compared to a negative dextrose control that contained dextrose in place of starch.

In tropical conditions, beef cows on pasture often experience protein restriction during mid-to-late gestation, potentially impacting offspring development negatively. To address this, we investigated the effects of strategic protein supplementation for pregnant beef cows fed low-quality forage during mid-gestation on the postnatal growth trajectory of their offspring.

Pigs are ideal species to convert food losses, also named former food products (FFPs), into animal proteins. The present study investigated the impact of incorporating sugary and salty FFPs into the diets of growing and finishing pigs on meat quality and its sensory characteristics.

High dietary crude protein (CP) is thought to antagonize nursery pig enteric health. Feeding high CP diets to nursery pigs did not exacerbate intestinal health or inflammation, and overall, protein level in the diet has little impact on animal health and performance.

Fescue has become the dominant cool-season perennial grass in the southeastern region of the United States and is also found in other countries. Endophytes from a plant–fungus symbiotic relationship produce toxic alkaloids that have caused significant annual economic losses to the livestock industry.

Issues associated with health and management of newly received cattle continue to pose significant animal welfare and economic challenges for the beef industry. Diagnosis of bovine respiratory disease, accompanied with poor growth performance, can be addressed by nutritional intervention in receiving cattle.

Low-cost genotyping platforms and sexed-semen have enabled the production of high breeding value dairy replacement heifers from a fraction of the herd representing the most elite cows. The remainder of the cow herd can be bred to beef bulls using male-sexed-semen.

Accurate identification of individual sheep is a crucial prerequisite for establishing digital sheep farms and precision livestock farming. In this study, we developed a lightweight sheep face recognition model, YOLOv7-SFR. Utilizing a face image recording channel, we efficiently collected facial images from 50 experimental sheep, resulting in a comprehensive sheep face dataset.

The goose industry plays important roles in economics, cultures, and ecosystems, yet the low laying and growth rates of many indigenous breeds hinders the development of the goose farming. Betaine, an important methyl donor, is commonly used as a feed additive in livestock and poultry to enhance animal growth.

Climate variability and uncertainty associated with weather patterns can greatly impact feed security for cattle producers. Flooding, drought, and temperature extremes can reduce a farmer’s ability to produce a consistent crop, resulting in feed prices that can fluctuate greatly.

Produced by the fungus Claviceps purpurea, ergot alkaloids (EA) are toxic to beef cattle when consumed and can lead to reduction in feed intake and growth performance, vasoconstriction of the blood vessels, hyperthermia, damage to extremities (ears, tails, and hooves) and in severe cases, death.

There is a pressing need to enhance livestock production efficiency to meet the growing global demand for meat. Carbohydrases and proteases are enzymes typically added to swine diets to improve nutrient utilization, leading to better growth rates and feed efficiency. This ultimately contributes to sustainable and economically viable pig farming.

A thorough understanding of the genetic factors that influence the feed efficiency of dairy cows is a prerequisite for planning and implementing selective breeding programs. Therefore, a systematic review of reported heritability, genetic markers, and biological pathways affecting FE-related traits in Holstein dairy cows was conducted and followed by a meta-analysis.

In this study, we aimed to determine the effects of a novel dental chew on the breath odor, oral health outcomes, and oral microbiota of dogs. Healthy adult dogs were used in a crossover design study to test a diet only (control) or the diet plus a novel dental chew.
