This review was focused on the effect of quality and quantity of feed on milk yield of dairy cows. Feed resource availability in quality and quantity has adverse effect on milk production on dairy animal. As per the effect of feed resource on milk yield of dairy cows in order to improve the effects in its quality to increase milk yield production level. The quality of feed resources availability in tropics and sub-tropics have not been extensively characterize for the different farming system. Tropical feed resources are generally limited in the supply of required nutrient for the optimum functioning of rumen micro-organisms. Dairy cattle require nutrients for maintenance, growth, production and reproduction. Nutrients required for these function expressed interims of energy, protein, minerals (mainly calcium and phosphorus) and vitamins. Besides the potential availability of non- conventional feed resources as stock feeds have not been exhaustively explored. With this regard the review reported that the effect of feed resources on milk yield of dairy cows and to improve feed quality and quantity management in improvement goals. Most dairy farmers tend to give more attention to the overall milk yield in their dairy cows and pay less attention to the overall milk components of a their dairy herd. However, consumers and dairy product producing companies that buy milk from dairy farms are more interested in milk components than milk yield. Hence, milk of dairy farmers known to produce milk that has high percentage of components such as fat and protein tend to be more profitable in markets than milk with low percentage of these components. Milk quality problems of the overall dairy herd of a farm are more likely affected by nutrition which is in turn affects milk composition. Therefore, poor knowledge of the relationship between dairy cow nutrition and milk components results in production of low quality milk with low milk.
