Hamed Zargaran Esfahani; Seyed Davoud Sharifi; Abbas Barin; Ahmad Afzal Zadeh

Volume 41, Issue 2 , September 2010

Abstract
  The effect of silver nanoparticles as additive on broiler performance was investigated through employed of 312 day-old broiler chiks (Arbor-Acre Plus) in a completely randomized design with 6 treatment diets each in 4 replicates. Corn- soy based diets were formulated for starter, grower and finisher ...  Read More

The Feeding Value of Waste Whole Date either with or without Enzyme Supplementation on Broiler Performance

Somayeh Shahsavari; Mohamad SalarMoeini

Volume 41, Issue 2 , September 2010

Abstract
  An experiment was conducted to study the effect of waste whole date, either with or without enzyme supplementation, on broiler performance. The chemical composition and metabolizable energy of the waste date were determined before a chick study of 3×2 factorial design arrangement, the treatments of ...  Read More
