Demand-oriented riboflavin supply of organic broiler using a feed material from fermentation of Ashbya gossypii

Alternatives to riboflavin (vitamin B2) production by recombinant microorganisms are needed in organic poultry production, but are cost-intensive, so that a demand-oriented riboflavin supply is necessary. Details on the riboflavin requirements of organic poultry are not available. A feed material with high native riboflavin content from fermentation of the filamentous fungus Ashbya gossypii was studied. Two runs with 800 Ranger Gold™ broilers each (40 pens with 20 animals) were conducted.

I risultati di uno studio: le api mellifere gestite con il metodo biologico hanno un'attività genica più sana rispetto alle api mellifere convenzionali

La salute delle api mellifere è influenzata da una miriade di fattori tra cui la diversità e la qualità del cibo a loro disposizione, l'esposizione ai pesticidi e gli attacchi di parassiti e malattie. L'attività genetica legata alla risposta immunitaria può essere misurata per indicare la salute dell'alveare.

Organically managed honeybees have healthier gene activity than conventional honey bees

The study is published in the journal Insects. The Honey bees are of great economic importance, not only for honey production but also for crop pollination. However, honey bee populations continue to decline mainly due to exposure to pesticides, pathogens and beekeeping practices. In this study, total soluble protein was measured, total RNA was extracted and first-strand cDNAs were generated.
