JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES Abstract The present mini review is based on the study of effect of Ocimum sanctum leaves powder/extract on body weight when supplemented to broiler chicken in feed/water. O. sanctum belongs to family lamiaceace and contains compounds such as carnosol, ursolic acid, rosmarinic acid, apigenin, eugenol, cirsilineol and cirsimaritin which are known to possess antioxidant properties. The reduced oxidative stress due to supplementation of this plant to broilers is found to enhance the growth rate and thus result in higher body weight. Keywords: Ocimum sanctum; Tulsi; Body weight; Growth; Broilers; Chicken Introduction Poultry farming is done at large scale throughout the world. They are raised for food both meat and eggs and are a source of income for a large part of our community. Growth and health are major concern in poultry farming. The motive of...

JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES   Abstract The European Commission (EC) Regulation establishes that, in organic production (OP), the choice of breeds should take into account their capacity to adapt to local conditions, their vitality and their resistance to disease. Poultry genotypes are selected mainly for productive performance and thus fast growth rate. This kind of selection induced a decrease of the biodiversity in poultry species by causing the extinction of some native breeds and loss of genetic variability. Although there is a negative linear correlation between adaptation to OP and daily weight gain, the FG chickens are still used in OP. Based on these considerations, the aim of the present review was to address the adaptation of chicken strains in alterative systems. The assessment of adaptability must be addressed with a multicriteria approach taking into account main aspects as: body weight, movement and fo...
