aflatoxins (afs) are one of the most important mycotoxins due to their common occurrence in feedstuffs and feeds that pose a serious threat to humans and animals. although many outbreaks of acute and chronic diseases have been attributed to consumption of aflatoxin-contaminated foods, the most significant effect of aflatoxin is hepatotoxicity in farm animals, especially aflatoxicosis in shrimps...

A study was conducted to determine the effects of a replacement finisher feed (RF) on carcass yield and carcass bacteria recovery. RF is a commercial formulation of a D-glucose polymer (maltodextrin) with added salts and vitamins. Commercial male broilers (41 d of age) were given either RF or control-feed (traditional starter feed) for 8 h, followed by feed withdrawal for 0, 4, 8, or 12 h befor...

This study was conducted to investigate the effect of a 12-h feed outage at various times prior to slaughter on subsequent broiler performance, live shrink, and processing yields. Broilers were full-fed or subjected to a 12-h feed outage followed by a refeeding period of 12, 24, or 48 h. Bird live weights or feed consumption was monitored during the outage and recovery periods. Birds were subje...

The cyclopoida copepod Oithona rigida has good potential for mass culture as a live feed. This study was carried out to investigate the effects of salinity on density of O.rigida four ranges with 15, 25, 35 and 45 ‰ and mass cultured under four salinity levels (15,25,35,and 45 ‰) in 5 L fiberglass tanks over 19 days culture period. However, it is better to be cultured at salinity of 35 ‰ for ma...

Optimizing larval rearing protocols is critical to successful intensive fish culture. We compared the efficacy of feeding strategies for larvae maraena whitefish Coregonus maraena, a promising candidate aquaculture. Survival, growth indicators, intestine development, and liver status were in fed live feed, commercial dried weaned from feed at 5, 10, 15, 20, or 25 days post hatching (dph). Seven...

Yeast additives have been fed to animals for more than 100 years. Although there are about 500 different species of yeast, the most common one fed to cows is Saccharomyces cerevisiae. Strains of Saccharomyces cerevisiae on the market today vary widely. The American Association of Feed Control Officials defines an active dry yeast as containing no less than 15 billion live yeast cells (cfu) per ...

freshwater microalgae and other plant-like organisms. They are used in the production of pharmaceuticals, diet supplements, pigments, and biofuels, and also used as feeds in aquaculture. Phytoplankton are cultured to feed bivalve molluscs (all life stages), the early larval stages of crustaceans, and the zooplankton (e.g., rotifers, copepods) that are used as live food in fish hatcheries. Flage...

The objective of this study was to compare growth performance and feed conversion ratios of rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis) juveniles in monoculture and duo-culture in freshwater and seawater under aquarium conditions. The fish were about 2-months old hatchery-reared brook and rainbow trout with initial weights of 0.934±0.033 (n=360) and 1.014±0.019 (...
