Research ArticleOpen accessPhrase in the titleUtilization of Eco-Feed Containing Mugwort Microorganism Compounds as a Feed Ingredient Source for Layer HensJassada Ruttanavut, Koh-en Yamauchi, Narin ThongwittayaProblem statement: Due to price hikes in feed, several strategies should be sought to reduce feeding costs. At the same time, there has been a considerable increase in environmental pollution from food waste. If food waste could be transferred into poultry diets, this would solve a great problem, helping poultry producers to reduce feeding costs, while reducing environmental problems arising … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 26 Apr 2011 · 8,372 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleCharacterization of Escherichia coli Isolates from Commercial Layer Hens with SalpingitisMahmood Salehi, Reza GhanbarpourProblem statement: Escherichia coli isolates are the most common bacterial agents of salpingitis in commercial layer hens. The objectives of this study were to determine the phylogenetic groups/subgroups and antibiotic resistance of E. coli isolates from salpingitis cases in commercial layer hens farms in southeast of Iran. Approach: One hundred twenty one E. coli isolates from oviducts of layer hens … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,950 accessesView PDFCite
