Dietary Pineapple Pomace Complex Improves Growth Performance and Reduces Fecal Odor in Weaned Piglets by Modulating Fecal Microbiota, SCFAs, and Indoles

mycolabadmin

Pineapple pomace, a leftover byproduct from pineapple processing, was tested as a feed ingredient for young piglets. When added at 2% to their diet, it significantly improved their growth rate and feed efficiency better than expensive imported fish meal. The pineapple pomace also made the pigs’ manure smell better by reducing foul-smelling compounds, while increasing beneficial gut bacteria that improve digestion and health.

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.

Effect of Dietary Insect Meal and Grape Marc Inclusion on Flavor Volatile Compounds and Shell Color of Juvenile Abalone Haliotis iris

mycolabadmin

Researchers tested whether using insect meal and grape marc as sustainable alternatives to fish meal in abalone feed would affect meat flavor and shell color. The study found that grape marc reduced unpleasant off-flavors in the meat while insect meal had minimal effect on flavor. Neither ingredient significantly changed shell color. These findings suggest these sustainable ingredients could improve both environmental impact and product quality in abalone farming.

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.
