Several authors demonstrated that dried AP could be ground and used as a feed-stuff in rations for both ruminants and non-ruminants. Bae et al. (1994) observed that cows fed total mixed ration containing 39% AP showed increased protein content but decreased lactose content in milk, when compared with cows fed the control diet. Milk fat and solid-not-fat were similar for both diets. According to the research conducted by Bowden and Berry (1958), when dry AP was included in rations for fattening pigs at the amount of 10%, no significant change occurred in daily gain, carcass quality and feed efficiency, compared to the control group fed a standard diet. Being a rich source of polyphenols, AP has a positive impact on animal health.
