it is well established that reproduction is sensitive to the state of energy reserves, and that there is a balance between energy homeostasis and fertility. in this view, this study examined the effects of different diets on growth and reproductive performance of fresh water angelfish. twenty four pairs of angelfish (weighing 3.58 ± 0.24 g) were fed with four types of diets including live earth...

Previous research has shown that the selective remembering of a speaker and the resulting silences can cause forgetting of related, but unmentioned information by a listener (Cuc, Koppel, & Hirst, 2007). Guided by more recent work that demonstrated both detrimental and beneficial effects of selective memory retrieval in individuals, the present research explored the effects of selective remembe...

An initial experimental study was conducted to evaluate the effects of binaural beats on fish growth performance. A 90-day trial with four triplicate groups was conducted with 240 zebrafish, Danio rerio, under aquarium conditions. Binaural beat file complexes were played for each aquarium using computer controlled directional speakers for 0 min d-1(Control), 90 min d-1(Group 1), 180 min d-1 (Gr...

the aim of the present work was to determine whether the administration of melatonin or l­-tryptophan (a precursor of melatonin) affects the immune responses and performance of broilers during induced exposure to aflatoxins in feed. the study was conducted from 0-6 weeks comprising six dietary treatments in triplicate with10 chickens in each replicate. the diets were formulated to supply 23% cr...

This study was performed to investigate the effects of dietary threonine (Thr). level on performance, metabolizable energy, intestinal morphology, and immune system in coccidian–infected broiler chickens. The diets contained: 88%, 100% (Non challenged (NC) and challenged control (PC)), 112%, 124%, and 136% of Thr requirement according to Cobb 500 recommendation and fed during grower (pre challe...
