Which vitamin is essential for feather development in poultry?

1. Vitamin A

2. Vitamin D

3. Vitamin E

4. Vitamin K

The correct answer is: Vitamin A

Vitamin A plays a crucial role in the development and maintenance of feathers in poultry. It is fundamental for the growth and differentiation of epithelial tissues, which include the skin and feathers. Adequate levels of vitamin A ensure that the feathers develop properly, as it contributes to the overall health of the feathers and the skin that holds them. Additionally, vitamin A is important for vision, immune function, and reproduction in poultry, which further underscores its significance in supporting the overall health of the birds, contributing to optimal feather condition and growth. This is particularly vital during the molting process and for young birds in their feathering stage, as sufficient vitamin A levels help in producing strong and healthy plumage.
