Research ArticleOpen accessIn the abstractEssential Oil Chemical Composition of Myrtle Growing in Northeastern Algeria and Estimation of its Antibacterial EffectivenessBarhouchi Badra, Aouadi Saoudi, Abdi AkilaThe aim of this study is to determine the antibacterial effectiveness of leaves essential oil extracted from myrtle growing in Algeria. A cluster analysis of soil and water was effectuated for performing chemical and granulometric analyses. The essential oil was isolated from leaves by hydro distillation and analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). The leaves yield reached a peak at … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 5 Apr 2016 · 8,356 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDRYING METHODS AND THEIR IMPLICATION ON QUALITY, QUANTITY AND ANTIMICROBIAL ACTIVITY OF THE ESSENTIAL OIL OF LAURUS NOBILIS L. FROM MOROCCOKhadija Dahak, Hafida Bouamama, Fatiha Benkhalti, Moha TaourirteThe effects of various methods of drying on the chemical quality and antimicrobial activity of the essential oil of Laurus nobilis were studied. The most prominent component in the air-dried, fresh leaf and microwave-dried leaf oils is 1,8 Cineole (58,8, 35.62 and 42,9% respectively). The essential oil has undergone significant chemical transformation in its monoterpenoids when the leaves of plant … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 20 Mar 2014 · 7,550 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Dietary Supplementation with Pumpkin oil (Cucurbita pepo) on Performance and Blood Fat of Broiler Chickens during Finisher PeriodHosna Hajati, Ahmad Hasanabadi, Park W. WaldroupProblem statement: Using most of antibiotic growth promoters as feed additives has been banned by the European Union due to cross-resistance against pathogens and residues in tissues; and scientists search for alternatives to antibiotics, two days. In this view, medicinal plants and essential oils extracted are becoming more important due to their antimicrobial and stimulating effects on animal digestive systems. … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 26 Apr 2011 · 9,724 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,101 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPotential, Implications and Solutions Regarding the Use of Rendered Animal Fats in AquafeedsJesse T. Trushenski, Rebecca T. LochmannProblem statement: In the past, aquafeeds were comprised largely of fish meal and fish oil derived from marine reduction fisheries. In addition to being highly palatable and readily digested by cultured fishes, these feedstuffs were historically inexpensive sources of protein, energy and essential nutrients. However, increasing cost and concerns over safety and sustainability have greatly incentivized the transition from fish … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 13,998 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Essential Oil from Citronella and Alfazema on Fennel Aphids Hyadaphis foeniculi Passerini (Hemiptera: Aphididae) and its Predator Cycloneda sanguinea L. (Coleoptera: Coccinelidae)Charles I. Abramson, Paulo A. Wanderley, Maria J.A. Wanderley et al.The essential oil of plants is used as an alternative to pesticides for the control of aphids. We study the effect of the essential oils of citronella and alfazema on aphid populations in the laboratory and in the field. We also investigate the effect of these oils on the behavior of the aphid’s principal predator the ladybug. The results show … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,392 accessesView PDF Cite

Review ArticleOpen accessIn the abstractEfficiency and Sustainability of Alternative Protein Sources for Livestock Production in Sub-Saharan Africa: A Systematic Review and Meta-AnalysisOlusegun Oyebade Ikusika, Bulo Luvuyo, Jaja Ishmeal FestusSub-Saharan Africa (SSA) faces growing challenges in sustainable livestock production due to high costs and limited availability of conventional protein sources such as soybean meal and fishmeal. This systematic review and meta-analysis evaluated the nutritional efficiency and sustainability of locally available alternative protein sources for livestock feed in SSA. Following PRISMA guidelines, systematic searches were conducted across five databases (PubMed, … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 19 Feb 2026 · 1,844 accessesView PDF Cite
