Research ArticleOpen accessEvery word in the titleClinical Pregnancy After Assisted Hatching Rate in Young women undergoing Intra Cytoplasmic Sperm InjectionMohammed Al-SunaidiProblem statement: The ability of a blast cyst to hatch, or escape, from the Zona Pellucida (ZP) that surrounds and protects the embryo during its first few days of development is one of many critical events that must occur for successful reproduction. Implantation of the embryo in the uterine lining is impossible unless hatching occurs. Hard or thick ZP will … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 13 Mar 2012 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Relationship Between Egg Weight of Olive Ridley Sea Turtle (Lepidochelys Olivacea) on Hatchability using “Maticgator” (Automatic Turtle Egg Incubator)Sukandar Sukandar, Sunardi, Vian Dedi Pratama, Zaenal AbidinSea turtles are reptile animals that live primarily in oceans but migrate to sandy beaches to produce and lay eggs in large quantities. However, the hundreds of eggs produced, only a dozen hatch and return to the sea. Also, factors of climate change and global warming have an impact on decreasing the wild sea turtle population, where female turtles are … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 2 · 7 Jun 2022 · 6,660 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Automatic IncubatorSiriluk Sansomboonsuk, Chagorn Phonhan, Girati PhonhanThe designing of an automatic incubator consists of three main parts. The first part is a mathematical model of an incubator. Thermo-physical properties of selected materials were substituted to investigate its heat transfer characteristics. The second part is the consideration of equipment used to measure and control temperature and humidity. The last part is to select the controller for an … …Energy Research Journal, Vol. 2, Issue 2 · 29 May 2012 · 14,918 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Geese Age on Their Productive and Reproductive QualitiesDanis Khaziev, Rinat Gadiev, Albert Farrakhov et al.This study aims to determine the optimal age for using breeder geese for hatching eggs. Four parties of experimental groups of geese of a large grey breed were formed to conduct a scientific and economic experiment. There were three groups of geese in each party, with the female geese aged 1, 2, 3 years and the male geese of 1,2,3,4 … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 29 Mar 2022 · 6,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Extended-Rotifers Inclusion and Live Food-Enrichment with Probiotics on the Survival, Metamorphosis, Development Time and Growth of Mud Crab, Scylla paramamosain (Estampador) LarvaeQuy Moc Ong, Ravi Fotedar, Thy Thi Truong HoThe present larval nutrition study was conducted to evaluate the effects of feeding probiotic-enriched rotifers inclusion mixed with Artemia until zoeal stages 4 (Z4) and Z5 on the survival, metamorphosis, development time and growth of mud crabs, Scylla paramamosain larvae. The efficiency of the feeding regime was tested by two-factor analysis. A 4×2 factorial experimental design with eight combinations of … …American Journal of Applied Sciences, Vol. 15, Issue 7 · 29 Sep 2018 · 8,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence and Inhibition of Microbial Load on Chicken Eggs with Special References to Egg Quality and HatchabilityJehan Ismail Ibrahim, H. Dalia Mansour, Hosny Abdellatief AbdelrahmanA total of 304 random chicken egg samples obtained from layers of Balady and Battery systems. 144 of chicken Balady and Battery eggs (72 of each sample were divided into 18 batches) were used for bacteriological evaluation. Enterobactriacae (94.4, 33.3 and 27.7%), Salmonella (77, 29 and 22%), E.coli (44, 0 and 22%) and Staphylococcus aureus (100, 97 and 98%) were … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 26 Dec 2014 · 7,847 accessesView PDFCite
Research ArticleOpen accessIn the abstractLife Cycle of Laboratory-Reared Acrobasis nuxvorella Neunzig (Lepidoptera: Pyralidae): A Pecan Nut PestCorella-Madueno Alba Guadalupe, Fu-Castillo Agustin, Harris Marvin et al.Acrobasis nuxvorella Neunzig is a monophagous pest that feeds on pecan nut trees, Carya illinoinensis. Its specific feeding habit makes the reproduction of this insect in the laboratory challenging. The objective of the present work was to replicate the biological cycle of A. nuxvorella under laboratory conditions. Different instar larvae of the insect were collected from infested nut trees. The … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 19 Sep 2012 · 8,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Adhesin Encoding Genes in Escherichia coli Isolates from Omphalitis of ChicksReza Ghanbarpour, Mahmood SalehiProblem statement: Omphalitis is one of the most common causes of mortality in chicks during the first week after hatching. Escherichia coli strains are the most common isolated bacteria from omphalitis cases of chickens. Bacterial colonization in the host cells surfaces is a critical first step in the pathogenesis of avian pathogenic Escherichia coli isolates. Thus the current study was … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 9,557 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Capability of Young Layers for Survival after Salmonella entritidis ChallengeE. S. Soliman, H. Busby, C. Kilpatrick et al.Problem statement: Genetic line differences in resistance of layer hens and young chicks to Salmonella entritidis have been identified through a lot of studies. That is why the agricultural industry was prepared for the potential phasing out of antibiotics for use in controlling bacterial pathogens. Early infection may result in long term colonization of layers with Salmonella entritidis, resulting in … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractMaize Oil Can Replace Fish Oil in The Diet of Grouper Postlarvae (Epinephelus Coioides) Without Adversely Affecting Growth or Fatty Acid CompositionJin Niu, Yong-Jian Liu, Li-Xia Tian et al.This experiment was conducted to evaluate the effects of dietary lipid sources on growth, survival and body composition of 40 day post hatch larval grouper, Epinephelus coioides. Fish were fed fish meal and protein hydrolysate based diets for 32 days with either 100% maize oil or 100% fish oil in triplicate from 40-day after hatching to slaughter size (fish weight: … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,279 accessesView PDFCite
