Nutritional Management of heat stress in poultry

Effect of vitamin E (100 and 200 mg/kg) and organic selenium (0.15 and 0.30 mg/kg) supplementation on performance, fertility, hatchability, immune responses and anti- oxidant responses during tropical winter and summer seasons were carried out. Supplementing combination of higher concentrations of organic Se (0.30 mg/kg) with either combination of vitamin E significantly improved antibody production to ND vaccine and anti- oxidant capacity of breeder animals. However, egg production, feed intake, feed required to produce an egg, average egg weight, hatchability was not affected by dietary supplementation of vitamin E and organic selenium in breeder diet.

 

Screening of herbs / spices for anti-oxidant properties by in-vitro methods at VCRI, Namakkal revealed that Curcuma longa (Turmeric) and Ocimum Sanctum (Tulasi) are having maximum anti-oxidant activities.
