ABSTRACT
It is beneficial to substitute Costlier commercial concentrates with locally available non-conventional feed ingredients. There are many other potential substitutes for reduction of cost. However inclusion of leaf meal as alternative feed ingredient can be a good option when we all are thinking to reduce cost of production. The inclusion of leaf meal to replace the costlier sources of protein is beneficial due to low cost of production of leaf meal, presence of protein greater in value to Maize (highest inclusion ingredient) and almost similar to legumes like pea, presence of carotene in higher amount than any other feed sources. Leaf meal products of good quality guaranteed to contain a minimum of 200000 IU of Vitamin A activity per kg of which the supply was 45000IU and 17% protein on average. Leaf meals are good sources of minerals as well. They are particularly rich in ascorbic acid and Vitamin A and contain significant amounts of Riboflavin. Researchers have shown same rate of body weight gain in broiler and swine whereas increased production in milk from cattle due to substitution of protein rich ingredient by leaf meal. Laying response from layer chickens have been increased and also of higher quality attributed by egg shape and increased yolk content due to presence of carotene. Researches on leaf meal have found the same response as provided by expensive feed ingredients, if proper detoxification methods like sun drying, heat treatment or the inclusion of Ferric Sulphate and Polyethylene Glycol (PEG) are used as remedy to combat toxins.
