Vitamin K is essential for synthesis of prothrombin, thus it plays an important role in clotting mechanisms and also has a protective effect against coccidiosis.
Deficiency of vitamin K may cause an increase of blood spots in eggs, haemorrhages in the legs and breast and a failure of blood clotting.
Wheat germ oil, fish liver oil, alfalfa meal, greens, germinated pulses, soybean oil, grains and fish meals are rich source of Vitamin A, D3, E and K.
Vitamin A is required for normal growth, reproduction and maintenance of epithelial cells in good condition (skin and the linings of the digestive, reproductive, and respiratory tracts).
Deficiency causes nutritional roup, characterised by conjunctivitis, oculo-nasal discharge, and eyelids stuck together with thick exudates. In advanced cases necrosis and keratinisation of mucosa of alimentary and respiratory tract occurs.
Fish liver oil and greens are rich sources of vitamin A.

Breeder hen diets should be supplemented with Vitamin K to ensure good chick health. Laying hens fed a diet deficient in vitamin k produce eggs low in the vitamin, and when the eggs are incubated, the chicks produced have low reserves and a prolonged clotting time. Vitamin A is easily destroyed in feed processing and storage. Usually, 10,000-15, 000 IU/ kg vitamin A is supplemented in broiler or broiler breeder commercial feed. High levels of vitamin A decreased egg production, size, and hatchability in laying hens.
