Microscopic sessile suspension feeders are a critical component in aquatic ecosystems, acting as an intermediate trophic stage between bacteria and higher eukaryotic taxa. Because they live attached to boundaries, it has long been thought that recirculation of the feeding currents produced by sessile suspension feeders inhibits their ability to access fresh fluid. However, previous models for t...

—We evaluated the influence of two broodstock feeding practices on fatty acid composition and viability of eggs in white bass Morone chrysops. The two dietary groups tested were (1) white bass females fed a commercially formulated feed (crude protein, 45%; crude fat, 16%) and (2) white bass females maintained on live food (fathead minnow Pimephales promelas and golden shiners Notemigonus crysol...

the effect of colistin sulfate on reducing salmonella enteritidis (s.enteritidis) infection in broilers and contamination from broiler carcasses was evaluated. 40000 birds in two separate houses were considered. colistin sulfate was added in to the feed of the test group as 100g containing 1,200,000iu/ton of feed for the whole period (56 days). to isolate s.enteritidis, samples were taken from ...

The number of sheep flocks in Brazil is increasing. It is known that lambs must be slaughtered when young for producing quality meat. The current study evaluated the inclusion of protected methionine, protected lysine, lysophospholipid and amylolytic enzymes in a diet to lambs and their effects on weight gain and quantitative carcass traits at slaughtering. Eighty non-castrated male crossbred D...

Fats and oils, a.k.a. lipids, are a chemically diverse group of compounds with the highest energy density among all major macro nutrients. Lipids play an important role in commercial turkey diets both physically and physiologically. From a physical standpoint, lipids are associated with processes related to improvement of live weight gain and feed efficiencies in commercial turkeys. Breeder tur...

to study the possible use of phytase and yeast (saccharomyces cervisiae) in corn-soy bean meal base diet with different levels of available phosphorous in arbor acers broiler chicks, an experiment was conducted with 264 day old chicks of an average weight of 44.6 grams each. a completely randomized design of 6 treatments and 4 replications (11 chicks per replicate) for periods of starter, growe...

twenty male raini goats with an average live weight of 30 ± 2.5 kg and 18 month of age. ,were used in a completely randomized design with 4 experimental diets and 5 replications to study effect of different levels by-pass(udp) protein(2.75, 4.86, 5.91 and 6.97 percent in dry matter) on growth and carcass characteristics. metabolismable energy (me) level of the all diets were similar (10.04 mj m...
