This research evaluated the suitability of commercially available larval feeds, Otohime B2 (OB2), Aller Infa (AI), and Aqua Start (AS), and one Experimental Feed (EF), for the weaning of largemouth bass (Micropterus salmoides), LMB. Feeds were presented with various ω-3 fatty acid levels/bioavailability (high in OB2 and AI), fat percentage (high in OB2 and AS), free amino acid and short peptide (FAA + SP) levels (high in OB2), and various soluble protein (SPR) levels (high in AS and EF). Fish were co-fed Artemia plus OB2 from the 19th to 22nd day post-hatching (DPH), then Artemia in addition...

The aim of the study was to prepare and test the effect of diets with 50% and 100% replacement of soybean meal with dehulled seeds of white lupin (Lupinus albus) variety Zulika. Two hundred and forty ROSS 308 broiler chickens were divided into control group (C) and two experimental groups E50 (50% replacement of soybean meal with dehulled white lupin meal) and E100 (100% replacement of soybean meal with dehulled white lupin meal). The production parameters and the amino acid spectrum of breast and thigh muscles were evaluated up to 34 days of age. Final live weight of broiler chickens was not significantly affected...

This study determined the effect of tryptophan (Trp) supplementation on the protein abundance of intestinal tight junction and indoleamine 2, 3-dioxygenase (IDO) in weaned pigs. Ninety-six White × Landrace × Duroc piglets (5.31 ± 0.54 kg) were selected in a growth trial and the experiment lasted for 30 days. The basal diet based on corn and soybean contained Trp at 2.4 g/kg. The dietary treatments consisted of a basal diet or a basal diet + 500 mg/kg Trp. On the 31st day, 12 pigs (1 pig per pen) were randomly selected and slaughtered in order to collect samples for subsequent analysis. Dietary supplementation with Trp improved the villus...

Industrial dairy farms boast highly advanced health monitoring and disease diagnosis systems. But without easily accessible, user-friendly web platforms for real-time decision-making, most dairy farmers cannot proactively manage herd health management and optimize treatments based on disease prediction and prevention. To bridge this gap, we have developed a web application of a Decision support system (DSS) for dairy health management based on machine learning. The system architecture combines a Flask backend with a React frontend and scalable cloud data storage and includes preprocessing, data integration, predictive modelling, and cost analysis....
