In 3 trials, the effects of dietary supplementation with phytase (PHY) and 25-hydroxycholecalciferol on BW and the blood characteristics of commercial layers that were inoculated prelay (12 wk of age) or at the onset of lay (22 wk of age) with F-strain Mycoplasma gallisepticum were assessed at 34, 50, and 58 wk of age. Experimental layer diets, which included either a basal control diet or the ...

Indirect methods such as masculinizing treatments by synthetic sex steroids has widely been used to produce all-female stocks in salmonids, but they have some disadvantage such as toxicity and high cost. Therefore, the main objective of this research was to develop indirect methods for the production of allfemale populations of Oncorhynchus mykiss through the use of natural steroids.In this stu...

Chronic exposure to high biofloc total suspended solids (TSS) could affect growth, red blood cells, and generate gill alterations in fish. Red pacu, Piaractus brachypomus, fry (2.7 ± 0.5 g weight) were exposed different TSS concentrations with low (T1: 200–300), medium (T2: 400–600 mg/L) levels compared a treatment control (TC) without during 45-day period 50 L experimental units (in quadruplic...

The rockworm gut flora was identified at each growth stage to elucidate the composition of bacterial community. source material Marphysa sanguinea fed regular feed and biofloc adult in parallel. systematic community determined based on next-generation sequencing method, alpha diversity beta were conducted access species within between communities, respectively. changed considerably as rockworms...

Vannamei shrimp (Litopenaeus vannamei) is one of the mainstay commodities that can increase country's foreign exchange because it has a fairly high selling value in global market. Several problems aquaculture reduce vaname production such as disease, water quality degradation, and feed conversion values. Biofloc an alternative technology be applied to overcome farming. There are two types biofl...

Aquaponics is a cultivation system that combines aquaculture and agricultural hydroponics. This study investigated the productivity of leafy vegetables cultivated in hybrid biofloc technology-aquaponics (HBFT-AP) using Japanese eel fed two kinds diets (Mash, commercial powdered feed extruded pellet [EP]) hydroponics (HP).The mash was to fish type dough mixed with water for 6 weeks (Exp1) switch...

the objective of this paper was to study the responses on productive performance, carcass characteristics and plasma constituents of modern broiler chicks to administration of cinnamon powder (cp) in the diet. commercial breeds (ross 308) of broiler chicks examined from 1 to 42 days of age. this experiment was conducted as a completely randomized design with 5 treatments and four replicates (15...
