A base mixture of agro-industrial byproducts with potential in the feed was developed based on the chemical analyzes made, resulting in the following food formula based on 3.5kg day ration; rice powder 1.17kg, arrocillo 0.46kg, minerals 0.02kg, salt 0.04kg, dicalsic phosphate 0.04kg, coconut cake 1.29kg, cocoa husk 0.41kg, urea 0.08kg. The effect of supplementation based on agroindustrial waste (treatment I: rice dust and Treatment II: supplement that includes 4 agroindustrial residues) in dairy cattle raised extensively in San Martin, PERU was evaluated. Ten cows in production integrated into the simple change design were selected with 2 periods of 21 days each (11 days of adaptation and 10 days of evaluation). During the evaluation phase, milk production per animal per day (Kg/day) and milk composition were measured based on the level of protein (%), fat (%) and lactose (%). The results showed significant differences in milk production (p <0.001) between supplementation with treatment II (10.2 kg / cow / day average) and treatment I (8.8 kg / cow / day average). No significant differences were found between the treatments with respect to protein (p = 0.923), fat (p = 0.899) and lactose (p = 0.828). It is concluded that a diet based on agroindustrial waste for feeding cows in production improved milk production without affecting the composition of the milk and the consumption of food.
