Summary: The redox system is crucial for cellular homeostasis, with disruption leading to oxidative distress and tissue damage. Commercially raised animals may be exposed to stressors affecting productivity, with dietary stressors causing oxidative distress and altering health. Understanding oxidative distress mechanisms from dietary stressors can aid in evaluating feed additives for mitigation.

Summary: This study systematically evaluated the energy efficiency and effectiveness of nutrient recovery from anaerobic swine digestate using electrodialysis. It identified the optimal operating conditions and proposed a conceptual design of cascading separation processes for digestate valorization. The findings provide insights into practical large-scale applications of digestate valorization through energy-efficient separation.

Summary: This study evaluated the impact of adding fermentable fiber, xylanase, and xylo-oligosaccharides on laying hen performance. The results showed that these additives can improve the utilization of dietary xylan, leading to improved nutrient utilization, performance, and gastrointestinal health in hens.

Summary: Increasing the inclusion of agricultural co-products in poultry feed to utilize nutrients at a low cost also increases the dietary fiber content, leading to challenges. The use of enzymes, advancements in feed processing, and specialized feed formulations have helped improve digestibility, though high dietary fiber remains an issue. Techniques like breaking down fiber into fermentable substrates with enzymes or using prebiotics and probiotics show promise in enhancing gut health and growth performance in poultry.

Summary: The experiment investigated the energy content of oats and the effects of oat particle size on nutrient and energy balance in growing pigs. Grinding oats to 619 μm was suggested for optimal energy utilization, while further grinding to 569 μm reduced calcium and phosphorus digestibility in pigs.

Summary: Lycopene, a natural red-colored pigment found in plants, has shown strong antioxidant activity and has been studied for its potential health benefits in animals. Recent research suggests that lycopene can be used as a natural antioxidant feed supplement to improve the health and performance of pigs and poultry.

Summary: Sodium bicarbonate pretreatment and solid-state fermentation were used to enhance the nutritional value of corn germ meal (CGM) by inoculating it with Bacillus velezensis CL-4, which has the ability to degrade lignocellulose. The pretreated and fermented CGM showed increased protein content and improved degradation of cellulose and hemicellulose. Electron microscopy revealed changes in the structure of the CGM substrate, indicating lignocellulose breakdown. Important metabolites were identified during the pretreatment process. These findings highlight the potential of using B. velezensis CL-4 for lignocellulosic biological feed production.

Summary: Organisms need to accurately sense and respond to nutrients for survival. Fungi have evolved genetic networks to regulate metabolic pathways and distinguish between preferred and nonpreferred nutrients. Transcription factors and regulatory genes play important roles in this regulation.

Summary: The study investigated the effects of moisture content and active aeration on soluble mineral forms of nitrogen and phosphorus in poultry litter. Higher moisture content led to increased phosphorus solubility but lower nitrification levels. Therefore, lower moisture levels are better for field application to maintain stable phosphate levels, while higher moisture levels may be suitable for low-cost phosphate recovery processes.

Summary: The present study aimed to characterize the performance of suckling piglets from high prolific sows and investigate the impact of milk composition on piglet growth during a 4-wk lactation period. The results showed that the stage of lactation influenced piglet growth, milk intake, nutrients in milk, energy in milk, and the energy metabolism of the suckling piglets. Moreover, maximizing milk protein concentration does not optimize piglet growth.

Summary: The supplementation of Carb improved weight gain and feed conversion rate in broilers fed barley-based diets, regardless of the conditioning temperature. However, increasing the temperature to 88 degrees Celsius decreased weight gain but increased feed conversion rate.
