  Naturally   occurring   toxins   in   plants   are   the   nature ' s   defensive   agents   for   the   plants   and   produce   deleterious   effects   in   livestock ,   and   known   as   Antinutritional   factors   (ANFs) .  Certain enzymes are also used to   supplement   the   naturally   occurring   enzymes   (e.g .   lipase). A   description   of   ANFs   and   methods   to   eliminate  / minimize   these   in   certain   feed   ingredients   are   given. In  poultry nutrition,  the   feed   ingredients are also supplemented with  feed supplements  such as toxin binders, antioxidants. Emulsifiers, vitamins, trace minerals etc.   SOYBEAN   (Glycine   max)   MEAL In  animal nutrition ...

  Bird performance has shown consistent improvement over the past few decades. This change has occurred due to improved genetics, precise nutrition and better farm management practices. The industry has undergone a remarkable growth over the last 30 years. Today we see 3 Kg broilers at 40 days of age and egg layers are capable of producing more than 330 eggs in 52 weeks of lay. Nutrition plays a vital role in supporting the desired growth and production performance of birds. Provision of good quality feed with essential nutrients must be ensured. Further, nutrients supplied through feed have to be effectively digested and absorbed. If the nutrients are not absorbed within the time limit, they are attacked by bacteria in the large intestine or excreted as waste, defeating the purpose for which they are fed and reflected in terms of poor growth and productivity. Feed accounts for 65-70% of the total costs in animal production. With the rise in feed costs internationally; the birds'...

 A healthy gut is essential for efficient conversion of feed into constituents for optimal nutrient absorption. Gut health is a complex process combining nutrition, microbiology, immunology and physiology. When gut health is compromised, digestion and nutrient absorption are affected, which in turn has a detrimental effect on feed conversion and production. This leads to economic losses and a greater susceptibility to disease.   A characteristic feature of a healthy gut is a large surface area covered with long healthy villi having deep crypts. Deep crypts are indicative of rapid tissue turn over in order to permit regeneration of damaged villi. Longer villi and deeper crypts provide a larger surface area for the absorption of nutrients, allowing efficient enzyme production and maturation of intestinal cells.   In commercial poultry production, it is said that profit comes from a healthy chicken. Healthy chicken comes from healthy gut. Healthy intestinal villi lea...
