Axenic cultures of free-living aerobic ciliates, such as Tetrahymena thermophila and Paramecium aurelia, have been established and routinely used in laboratory research, greatly facilitating, or enabling characterization of their metabolism, physiology, and ecology. Ruminal protozoa are anaerobic ciliates, and they play important roles in feed digestion and fermentation. Although, repeatedly at...

Live feed is the basic food source and nutrient security for successful seed production of any commercially important aquaculture species fishes, mollusks crustaceans. Both plant animal originated aquatic microscopic organisms are generally termed as live food. They items in early stages (larval stage) life cycle due to small sizes, easy digestibility enriched nutrients. The Nannochloropsis sp....

There are innumerable varieties of devices available for the supply of fluid media to continuous culture systems. The unit presented here offers the advantage of being an inexpensive system with a high degree of reliability. No moving parts or pumps are required, and functional models can be constructed from routine laboratory ware. The primary problem with gravity flow or "drip" systems has be...

A balance trial experiment was carried out to evaluate the potential relationship between an enzymatically hydrolyzed yeast (EHY) and yeast culture combined with a live Bacillus subtilis (Bs) on the productive parameters, ileal digestibility, retention of nutrient and energy and villus morphology in broilers. Seventy two 28 d old, Ross B308 male broilers were assigned to a factorial combination...

This study was carried out to investigate the effect of humic acids (HA) supplementation provided through drinking water on performance, carcass and some gut traits of broilers. In a randomized design, 480 mixed-sexes Ross 308 broilers were allocated into four experimental groups consisted of four replicate (30 birds per replication). All birds were housed in pens over 42 day. All chickens were...
