Vitamin E supplementation – revised recommendations for organic dairy cow production
Vitamin E is essential , and supplementation to the diet is often needed to meet the requirements of cows . Current supplementation recommendation s may be overestimated in forage -based systems where grazing or grass -clover silages are the basal diet, with low to moderate levels of concentrate feed. An update of the requirements and […]
Revision of Vitamin E recommendations for organically managed dairy cows
Vitamin E is essential and supplementation to the diet is often needed to meet the requirements of farm animals. This is particularly relevant during long indoor periods where conserved forages must be fed, as conservation can degrade Vitamin E. However, synthetic vitamins are regarded as contentious inputs in organic agriculture. Therefore, the aim of this […]

Effects of riboflavin supplementation level on health, performance, and fertility of organic broiler parent stock and their chicks
Data from breeder hens and chicks are particularly critical for the development of vitamin B2 recommendations for organic poultry. To test safe thresholds of supplementation, 100 breeder hens (Hubbard JA 57 K) and ten cockerels were allocated to ten housing groups, with each receiving supplementation of either 4.0 (treatment CON) or 2.5 mg (treatment RED) riboflavin per kg feed.

The State of Play of Copper, Mineral Oil, External Nutrient Input, Anthelmintics, Antibiotics and Vitamin Usage and Available Reduction Strategies in Organic Farming across Europe
Although input use in organic agriculture is strictly regulated, and significantly less contentious inputs are applied in organic than in conventional farming systems, copper, mineral oil, external nutrient input, anthelmintics, antibiotics and vitamins are still commonly used among organic farmers in the EU, partly due to the scarce availability of alternative products and the difficulty […]
