Total Gut Integrity (TGI) can be defined as “the maintenance of intestinal health to enable the expression of the full genetic potential for growth and yield and to fully utilise the dietary nutrients”. A sound gut is a must for the best production performance of a poultry bird. The better the digestive performance, the better will be the productivity and profitability of the farm. In recent years, the problems associated with total gut integrity (TGI) have been the major reason behind huge losses to the poultry industry. Dr Srijit Tripathi, of Ayurvet Limited, discusses the factors which can be responsible for the impaired gut of a bird.
