OBJECTIVES The objective of the present study was to investigate the lipid and the antioxidant regulatory potential of a multigrain diet in laboratory animals with reference to lipid profiles, tissue lipid peroxidation and antioxidant status. METHODS Two types of diets, with or without addition of cholesterol, were used in the study - a commercial diet and a formulated multigrain diet (with S...

The effects of temperature and diet on the growth of captive year 0 specimens of Opansus tau were examined for two consecutive year classes. The 2001 year class was raised at about 23, 26, or 29 degrees C and provided with live brine shrimp, frozen butterfish and squid, or commercial food pellets (45% protein, 19% fat, and 3% fiber) three times per week. Maximal growth was achieved with the pel...

A 70-day experiment was carried out to evaluate biofloc system operation with no carbon addition by manipulating dietary protein and lipid levels for Nile tilapia (Oreochromis niloticus) cultivation. Three treatments were conducted; Control treatment (C; fed on a 30% crude [CP] diet supplemented 3% vegetable oil [VO] + of external source [ECS] in rearing tank), low protein–low (LPLL; 23% CP (VO...

This study examined the effects of feeding of two dietary probiotics on growth performance and feed utilization, intestinal colonization and related health criteria, biochemical parameters, hematological indices, and immune parameters and protection against Yersinia ruckeri in Oncorhynchus mykiss during a period of 56 days. The study included 3 groups:1(a control group of fish, 2) a group of fi...

The present work was aimed to study the effect of dietary L-arginine level, vitamin C, and their interaction between them on some productive performance Matrouh laying hens during summer season. A 4X3 factorial treatment arrangement carried out including four levels L-Arg (0.0, 0.4, 0.8, 1.2 g/kg diet) three VC concentrations (0, 150, 300 mg/kg diet). total number 108 (Egyptian local strain) ag...

Phytogenic feed additives are plant-derived products used in poultry feeding to improve overall performance of broilers. In this study, 588 one day-old Cobb 500 chicks were fed one of four diets and housed on either dirty or clean litter for 3wks. Treatments included: Group I: commercial diet with no additive and housed on clean litter; Group II: commercial diet with no additive and housed on d...

Curcumin (diferuloylmethane), a yellow pigment that is obtained from the rhizomes of Curcuma longa Linn., is a major component of turmeric and is commonly used as a spice and food-coloring agent. The inhibitory effects of feeding commercial grade curcumin (77% curcumin, 17% demethoxycurcumin, and 3% bisdemethoxycurcumin) in AIN 76A diet on carcinogen-induced tumorigenesis in the forestomach, du...

This research aimed to compare the effects of pigments extracted from dried petal meal of marigold flower and synthetic pigments on productive performance of laying hens, egg quality and antioxidant properties of the egg. A total of 64 laying hens, aged 75 weeks, were distributed in a completely randomized design in 4 treatments and 4 replications containing 4 hens per cages. Experimental group...

Pangasianodon hypopthalmus can be reared under biofloc system and short photoperiod. To understand the effect of photoperiod manipulation to wards blood structure P. a study was conducted on September December 2020. This experiment using factorial CRD design with 2 level for B factor (biofloc no biofloc), 3 P (Natural, 18 hours dark, 24 dark), repetition. The fish in 110L tank, 30 fishes/tank, ...
