Abstract: The egg producing industry discards old stock to keep a dynamic population, which is dehydrated and pulverised to obtain a meal which is used as a source of amino acids, essential fatty acids and minerals. The resulting product is called Poultry By-Product Meal (PBM). The present study was undertaken to assess the impact of the addition of PBM to dairy cows feed on milk production. Nine mid-lactation (averaging 50 days in milk) were blocked as low, medium and high milk producers. Animals were individually stationed to monitor feed intake and dairy yield. The amount of PBM added to a corn silage based ration was 0, 500, or 1000 g day 1, also ground sorghum and vitamin-mineral premix were utilised. In a general manner, the addition of PBM improved most of the production parameters (p<0.05) of cows. Hence, adding PBM as protein source to cow feed improves the milk production and characteristics in the mid-lactation stage.
