It is important to consider the nutritional implications of a beak trimming ban.
While feather pecking is a welfare issue itself, the practice of beak trimming is also under scrutiny. There are many reasons why pecking behaviors start, but one under control of nutritionists is the potential drive to find another source of protein or fiber. Optimal diet formulation is essential in both rear and lay. Deficiencies, particularly in amino acids, or a lack of fiber could result in feather pecking as birds seek the nutrients that they need. However, a ban on the practice driven by market pressure is particularly difficult in non-cage laying systems where bird interactions are much greater.
