tailieunhanh - General performance observations in broiler chickens experimentally inoculated with salmonella enteritidis and its amelioration with vitamin C

The present study was conducted to evaluate the effect of Vitamin C on the pathogenesis of Salmonellosis in broiler chickens. Seventy two, day old broiler chicks were divided into 4 groups-I, II, III and IV. Group I served as control. Group II was administered Salmonella enteritidis (LD50=2x108 organisms) orally. Group III was administered Salmonella enteritidis (LD50=2x108 organisms) orally and Vitamin C mixed with water @200ppm. Group IV was administered with Vitamin C mixed with water @ 200ppm. Clinical signs developed up to 3rd week PI (Post-infection) with decreased severity in group III. A mortality of and was recorded in group II and III respectively. Infected birds showed significant decrease in body weight, weekly body weight gain, feed intake and increase in FCR. Vitamin C significantly improved these parameters from 3rd week PI. | General performance observations in broiler chickens experimentally inoculated with salmonella enteritidis and its amelioration with vitamin C
