Effects of dietary Fibrafid as phytogenic supplementation in standard and nutrient-reduced diets on breast meat quality, carcass traits, histopathology, and feed efficiency in heat-stressed broilers

mycolabadmin

This research tested a plant-based feed additive called Fibrafid in broiler chickens raised in hot conditions. When included at 0.25% in their diet, Fibrafid improved meat quality by increasing its ability to retain moisture and enhancing tenderness, while also supporting growth even when using lower-nutrition diets. The additive maintained healthy intestines and improved feed efficiency, offering a practical and sustainable solution for poultry farmers in hot climates.

Effects of fiber sources with different solubilities on the growth performance, nutrient metabolism, antioxidant, immune capacity and intestinal health of meat geese

mycolabadmin

This study examined how different types of dietary fiber affect the health and growth of meat geese. Researchers compared three fiber sources with different levels of solubility: wheat bran (highly soluble), alfalfa meal (moderately soluble), and bamboo meal (low solubility). They found that the highly soluble fiber source improved growth, enhanced immune and antioxidant functions in the intestines, and promoted beneficial bacteria, making it the best choice for geese farming.

Growth performance, meat quality, cecal microbiota and metabolomics profile of turkeys fed diets containing black soldier fly (Hermetia illucens) meal

mycolabadmin

Researchers tested using black soldier fly meal as a protein source in turkey feed to replace traditional soybean meal. Turkeys fed diets containing 5% BSF meal from mid-growth to slaughter showed better growth and weight gain with minimal changes to meat quality. The improvements appeared to be linked to beneficial changes in gut chemistry rather than changes in gut bacteria, making BSF meal a promising sustainable protein alternative for poultry farming.

Individual and Combined Effect of Zinc-L-Selenomethionine Complex with Mannan-Oligosaccharide on Growth Performance, Carcass Characteristics, Gut Development and Immune Response in Broilers

mycolabadmin

This study tested whether combining organic selenium and a prebiotic from yeast could improve broiler chicken health without using antibiotics. The researchers fed different groups of chickens either selenium alone, the prebiotic alone, or combinations of both at different levels over 35 days. They found that the combination of higher selenium levels with the prebiotic worked best for improving meat quality, immune system strength and gut health, making it a promising natural alternative to growth-promoting antibiotics in chicken farming.

Effects of a biotechnologically produced Pleurotus sapidus mycelium on gut microbiome, liver transcriptome and plasma metabolome of broilers

mycolabadmin

Researchers tested whether mushroom mycelium (the root structure of mushrooms) grown in large bioreactors could be used as a supplement in chicken feed as a sustainable alternative to traditional ingredients. Over 5 weeks, broilers received feed with 0%, 2.5%, or 5% mushroom mycelium, with no negative effects on growth, digestion, or overall health observed. The study suggests that this biotechnologically produced mushroom biomass is a safe and potentially sustainable feed ingredient for poultry production.

Influence of Pleurotus sapidus fruiting bodies on the performance, cecal microbiome, and gene expression in the liver and breast muscle of broilers

mycolabadmin

Researchers tested whether edible mushroom fruiting bodies could be used as animal feed for chickens. They found that chickens fed diets containing oyster mushroom (Pleurotus sapidus) had reduced growth and lower nutrient absorption compared to control chickens. While mushroom-based feed appeared to increase beneficial gut bacteria diversity, it ultimately impaired overall chicken performance, suggesting mushroom fruiting bodies are not suitable as a primary feed component for commercial poultry production.
