The researchers studied how adding berseem to cattle diets affects their digestion and nutrient utilization. They fed different levels of berseem to cattle along with wheat straw and measured their intake and digestion. They found that adding 30% berseem to the diet was the best for the cattle's stomach bacteria, leading to increased food intake and digestion. Beyond this level, adding more berseem did not improve digestion further. This study shows that berseem can be a beneficial supplement for cattle diets, improving their ability to digest food and utilize nutrients effectively.
