Immunomodulatory effects of heat stress and lipopolysaccharide on the bursal transcriptome in two distinct chicken lines
Transcriptome analysis identified genes and pathways involved in bursal responses to heat stress and LPS and elucidated that these effects were greatest in the combined treatment. The interaction between heat and LPS was line dependent, wit ...

Efficacy of mycotoxin detoxifiers on health and growth of newly-weaned pigs under chronic dietary challenge of deoxynivalenol
Mycotoxin detoxifiers could partially overcome deoxynivalenol toxicity enhancing liver health, whereas CYE and CYB reduced oxidative stress, and CYC and CYB reduced immune activation. In conclusion, yeast-based detoxifiers with functional c ...

What poultry producers should know about endotoxins
Effective endotoxin management is a crucial task for poultry producers, allowing them to safeguard their animals' health and productivity. In this first part of our two-part series on endotoxin management for poultry, we look at the str ...

Lipopolysaccharide induces acute bursal atrophy in broiler chicks by activating TLR4-MAPK-NF-kB/AP-1 signaling
We investigated the mechanisms that induce atrophy of the chicken bursa of Fabricius (BF) upon lipopolysaccharide (LPS) treatment in young chicks. LPS treatment resulted in ~36% decrease in bursal weight within 36 h (P < 0.01). Histological ...

Endotoxin translocation and gut inflammation are increased in broiler chickens receiving an oral lipopolysaccharide (LPS) bolus during heat stress
Lipopolysaccharides (LPS), also termed endotoxins, are the major component of the outer membrane of Gram-negative bacteria. In general, endotoxins in the intestine are considered harmless in healthy animals. However, different stressors, su ...

3D approach to mycotoxin risk management in livestock and poultry
Livestock and poultry feeds and its raw materials are susceptible to fungal/mold colonization. Major plant-based animal feed raw materials around the world include maize, wheat, broken rice, millets, soybean meal, sunflower meal, rapeseed m ...

Protecting gut health and animal performance during heat stress conditions - Research Insights
2020 tied with 2016 as the warmest year on Earth. As climate changes continue to present challenges for livestock producers – even in northern climates – research suggests that feed additive interventions can help manage animal health and p ...

Impact of medium chain fatty acids, their monoglycerides - and agglomerates of them with diformates against bacteria and viruses - Part II Anti-viral effect
In the first part of this "mini-series" the anti-bacterial impact of medium chain fatty acids and monoglycerides in conjunction with organic acids had been discussed. It was revealed that the addition of 3rd generation acidifier i ...

Impact of medium chain fatty acids, their monoglycerides - and agglomerates of them with diformates against bacteria and viruses - Part I: Anti-bacterial effect
MCFAs (defined as saturated fatty acids with C6 to C12 hydrocarbon chains) and their corresponding monoglyceride derivatives are single-chain lipid amphiphiles.

Application of GroPro in low fish meal diet
Fish meal has been traditionally the first choice of protein source in aquafeeds for many reasons, including its high protein content, excellent amino acid profile, high nutrient digestibility, general lack of antinutrients and wide availab ...

Role of organic Se in sustaining egg production in aged laying hens under heat stress
Under heat-stress conditions (i.e. high temperature and humidity) and as the hen ages, oxidative stress increases due to the synthesis of reactive oxygen species (ROS). When the hen is unable to neutralize the various ROS molecules that are ...

Revisiting oxidative stress and the use of organic selenium in dairy cow nutrition
Among feed-derived antioxidants, selenium (Se) was shown to have a special place as an essential part of 25 selenoproteins identified in animals. Organic Se, in the form of selenomethionine (SeMet), has been reported to be a much more effec ...

Oxidative stress in the poultry gut: Potential challenges and interventions
The gastrointestinal tract (GIT) provides the biological environment for nutrient digestion and absorption, and protection from pathogens and toxins. Broilers are fast growing because of the great potential of intestinal epithelia for nutri ...

When is an enzyme in feed, not a feed enzyme?
Feed enzymes increase the nutritional value of poultry feed, but other kinds of enzymes can be used to improve gut health. Bacterial peptidoglycans negatively affect gut function – these enzymes help break them down, increasing produc ...
