[ 1 ] - A comparative study on the colonization of Salmonella enteritidis hilA mutant and its parent strains in laying hens
BACKGROUND: Several regulatory proteins are involved in Salmonella invasion. The key regulator of SPI-1 (Salmonella pathogenicity island 1 ) is hilA, a transcriptional activator encoded on SPI-1 that regulates the expression of the SPI-1 secretion system. OBJECTIVES: Importance of hilA mutation on S. enteritidis colonization and shedding in layer hens was evaluated in a long-term experiment. ME...
[ 2 ] - Comparative study on the beneficial effects of different dark-length schedules on the incidence of ascites and metabolic parameters in fast growing broiler chickens
BACKGROUND: Increasing of oxygen consumption in fast-growing broiler chickens is associated with the more pronounced occurrence of right ventricular hypertrophy and ascites. While, rearing of susceptible chickens in dark condition could reduce the metabolic rate of birds and hence the incidence of ascites. OBJECTIVES: The present study was designed to investigate a comparative study on the inf...
