The requirements from the breeding companies are currently too high.”<\/em>\r\n\r\nIn general, we see high levels of calcium in diets beyond those that the company has formulated. So we are trying to work on projects that actually give the tools to the commercial nutritionists to reduce calcium in the diets while maintaining digestibility.<\/strong> It is because calcium is [register] a very reactive nutrient and it has negative effects on the digestibility of other nutrients said Dr. Roselina.\r\n\r\nOther discussed topics during the interview were:\r\n
