Calcium soaps and hydrogenated vegetal fats: effects on concentrates quality (durability, etc.)

In ruminants concentrates, oils\fats inclusion is lower that in monogastrics' ones, where low durability and pasty textures can be found due to high inclusion of fats. In ruminants diets, where fats level of inclusion is lower, do you have any data\and or experience regarding the effect of calcium soaps of fatty acids (and\or hydrogenated fats) on pellet quality?
