Widespread occurrence of H9N2 low pathogenic avian influenza (LPAI) viruses in many Asian countriesduring the past decade has resulted in the need for evaluation of the pathogenesis of H9N2 virus infection. In this study, tissue tropism and dissemination of A/Chicken/Iran/772/1998(H9N2) virus throughout the body of broiler chickens were investigated. The clinical signs, gross lesions and antibo...

Electrostatic space chargers were used to impart a negative charge to airborne dust particles and thereby cause them to be attracted to grounded surfaces. To determine whether negative air ionization could affect the airborne transmission of Salmonella enteritidis, chicks were housed in four controlled-environment isolation cabinets in which airflow was directed across an unoccupied central are...

Fructose and lactate markedly stimulated fatty acid synthesis from [lJ4C]acetate in isolated cells prepared from the livers of unfed neonatal chicks (21 or 22 days of incubation). In liver cells obtained from unhatched chicks (19 days of incubation) fructose and lactate had very small stimulatory effects on fatty acid synthesis. The increase in fructoseand lactate-stimulated fatty acid synthesi...

Lysine is frequently a first- or second-limiting amino acid in poultry diets. Improving the efficiency of lysine use for protein synthesis would effectively lower the lysine requirement and decrease feed costs. Understanding how lysine is degraded and how the degradation is regulated would identify potential molecular targets for interventions to decrease lysine degradation. To better understan...

Two Hundred and six day old Fulani Ecotype chicks (FEC)were used to investigate the effect of feeding two types diet (Chick starter Broiler formulated meet standard nutritional requirement pullets broiler chicks) on growth traits performance from O 8 weeks. The contained 23% Crude Protein (CP) 3000Kcal/kg Metabolizable Energy (ME), Chick 21% CP 2800Kcal/Kg ME. measured were body weight (BW), le...
