The aim of the present study was to examine effects dietary inclusion fermented poultry by-product meal (FPBM) on growth performance, digestive enzymes activity, innate immunity, and antioxidant capacity in Nile tilapia (Oreochromis niloticus). A basal diet containing fish soybean considered as a control (Con), four other diets were produced by 10, 20, 30, or 40% FPBM (FPBM10, FPBM20, FPBM30, FPBM40 diets). experiment done triplicates (20 per replicate) fed test visual satiety twice daily...
The paper considers robust stability properties for Schur polynomials of the form f(z) = Σi=0 nan-izi By plotting coefficient variations in planes defined by variable pairs ai, an-i each i and requiring such plane region obtained coefficients to be bounded lines slope 45°, 90° 135°, we show that all comer points is necessary sufficient any region. Using this idea, one can construct several necessity differing sufficiency conditions where ai vary independently an interval [ai, a- i]. As...
Abstract The paper considers robust stability properties for Schur polynomials of the form . By plotting coefficient variations in planes defined by variablei-o pairs a,-, an.{ each i and requiring such plane region obtained coefficients to be bounded lines slope 45°, 90° 135°, we show that all corner points is necessary sufficient any region. Using this idea, one can construct several necessity differing sufficiency conditions where aI vary independently an interval [ a , ā ]. As become...
Abstract Four diets were prepared to include a mixture of medium-chain fatty acids and taurine as digestive/ metabolic enhancer (DME, AQUAGEST ® ) at 0, 1, 2, 3 g DME/kg diet fed common carp (initial weight, 4.55±0.03 g) for 70 days. Dietary DME significantly increased the final weight gain, specific growth rate, feed intake, protein efficiency decreased conversion ratio in dose-dependent manner (P<0.05). The body lipid composition was improved by feeding 2 g/kg (P=0.0141). intestine...
Abstract The current study was carried out to investigate the effects of Saccharomyces cerevisiae- fermented poultry by product meal (PBM) on growth performance, micromorphological, and immunological changes in common carp. Five experimental diets were prepared include PBM at 0, 5, 10, 15, 20 % level diet carp (4.91±0.01 g). fish reared for 90 days these diets. obtained results revealed that yeast significantly changed final body weight (FBW), gain (WG), specific rate (SGR), feed intake...
ABSTRACT: The effects of electrical stimulation on muscle fiber type, meat quality, and composition Longissimus thoracis muscles from one‐humped camels Dofari Omani cattle a comparable age range were investigated. A low‐voltage with 90 V, 14 Hz (pulse 7.5‐millisecond duration every 70 milliseconds) 20 min postmortem was applied. Samples the left collected (2 to 3 y) 24 (1 y). For chemical composition, samples dried in freeze dryer, then ground determine moisture, protein, fat, ash. Macro‐...
This comparative study was conducted to access the drought tolerance and yield stability in different genotypes of barley.Study growing seasons 2013-14 2014-15 by imposing two water regimes viz.optimal stressed.Result revealed sufficient genetic variability among genotypes, substantial expression potential importance selection based on stress condition.The mean squares irrigation explained most variations for all traits both seasons, indicating relative tolerance.Water deficient conditions...
Purpose The purpose of the paper is to study effects cooking on proximate composition, amino acids, fatty minerals and total, heme non‐heme iron content camel meat. Design/methodology/approach A total ten longissimus thoracis muscles (500 grams) were collected between tenth twelfth ribs left side. Samples randomly from two three year old carcasses chilled (1‐3°C) for 48 hours then stored at −20°C. first portion was kept fresh while second one placed in plastic bags cooked by immersion a...
Ten Egyptian barley genotypes (2 commercial varieties and 8 breeding lines) were cultivated under normal condition at the Experimental Farm of Sakha Agricultural Research station exposed to salinity stress El-hosainia plain station, Elsharkia Governorate, Egypt, in an attempt identify relative tolerant genotypes. A susceptibility index (SI) was used estimate loss because it accounted for variation yield potential intensity. Giza 123, Line-1, Line-5, Line-6 Line-8 considered as saline on...
Abstract Tannins have been implicated in the resistance of some cotton varieties to insect attack. The relationship between tannin concentration and susceptibility Egyptian piercing sucking insects has undertaken present work. Eight derived from Gossypium barbadense one variety G. hirsutum were evaluated. There is a significant negative linear tannins two varieties, Giza 70 76, population density insects. On contrary, positive correlation existed infestation concentrations 80 81. This may be...
A colony of Aphidoletes aphidimyza (Rond.) was reared on brussels sprouts infested with Myzus persicae (Sulz.) for many generations. In the present investigation, females laid more eggs than artificial leaves. The majority underside even if it morphological upper surface. Brussels preferred against turnip cabbage, sugar beet and beans but not oil‐radish oviposition. After three generations leaves were slightly sprouts.

Abstract Background Visceral artery pseudoaneurysms (VAPAs) are rare, potentially life-threatning aneurysms found in the celiac, superior, or inferior mesenteric arteries. They most common splenic (60-70%), followed by hepatic arteries (20%) and celiac (10%). Usually asymptomatic, VAPAs often discovered incidentally during abdominal imaging. pose a high risk of rupture haemorrhage. Risk factors include iatrogenic injury trauma. Traumatic extremely rare with unclear management guidelines....
Climate change significantly threatens crops, mainly through drought stress, affecting barley, which is essential for food and feed globally. Ten barley cultivars were evaluated under normal stress conditions during the 2019/20 2020/21 seasons, focusing on traits such as days to heading maturity, plant height, number of spikes m−2, spike length, 1000-kernel weight, biological grain yield. Drought reduced most these traits. The genotypes showed significant differences in their responses...
Abstract The present work deals with the effect of three plant species family Leguminosae on cow pea aphid. From data obtained, it was clear that broad bean highly acceptable as food and can support growth well, whereas clover termis proved to be largely resistant for Aphis craccivora infestation not well. Poor related a low rate feeding which may have been due nun‐nutrient deterrents. Thus biochemical analysis plants indicate presence coumarin in variable concentrations. percentage...
To evaluate the resistance of some barley genotypes for net blotch disease and grain yield its related traits, twenty (12 local varieties 8 exotic lines) were used. Expression severity to foliar infection varied between evaluated genotypes, Giza 117 2000 appeared highest response, 123, 124, 126 131 moderately susceptible, while other ranged resistant resistant. Line 81 91 proved be most blotch. Moreover, 133 line showed superiority in values over all tested high reaction disease. Genetic...
