Due to the high content of crude protein and high concentration of unsaturated fatty acids, pumpkin seed cake could be a good quality feedstuff for ruminants. There is an increased interest in finding alternative protein feeds that can be produced to substitute concentrate components of diets. This study was conducted to evaluate pumpkin seed cake as a substitute for the concentrate component in the diet of lactating cows based on milk production. Eight lactating cows were included in this study with 21 days period of investigation. The cows were divided into two groups: group one was in 60-90 days of lactation and group two was in 120-150 days of lactation. Milk production was measured for 7 consecutive days, from days 1 to 7, 8 to 14 and 15 to 21, respectively. Results of this study showed that pumpkin seed cake is a great source of protein (65.49% of DM) for ruminants, end especially for high producing cows. An increase in milk yield was recorded in this study by 6.68% in the first cows group, and by 7.92% in the second cows group where cowʼs diet was supplemented with pumpkin seed cake.enCC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/pumpkin seed cakecows’ nutritionmilk yieldconferenceObject
