Gross and Siegel (1993) suggested that reference values for the heterophil to lymphocyte ratio of about 0.2, 0.5 and 0.8 are characteristic of low, optimal ...
High environmental temperatures have deleterious effects, reducing the feed intake, live weight gain and feed efficiency of poultry. A study utilizing Ross 308 was conducted to evaluate the effects of vitamin C (Ascorbic acid) and glucose on broilers production reared under heat stress (32 ± 2 °C). One day-old, five hundred twenty five broilers were randomly assigned to 7 treatment groups with ...

The effect of ascorbic acid (AA) and butylated hydroxyanisole (BHA) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for AA and BHA) in diet containing 1 ppm total aflatoxin (AF: 76.45% AFB1, 10.52% AFB2, 9.89% AFG1 and 3.14% AFG2). A total of 300 day-old broiler chicks were divided into ten treatment groups (T1=control; T2...
