p. 163 - 170 CERTAIN ASPECTS REGARDING THE USE OF MARINE ALGAE FOR POULTRY FOOD Maria Stadniciuc Institut Roumain de Recherches Marines Constanta Elena Calotoiu Palas Experimental Station, Constanta Abstract By investigating the effect of administrating seaweed to the poultry food, the authors found that marine algae possess a quite significant nutritive value and that such algae may substitute up to 20% of the normal daily ratio. It has also been found that algae, particularly green algae, when consumed fresh or frozen, show a favourable action on the colour of the yolk. For poultry fed with 5-7% fresh algae (Cladophora), the yolk showed a colour twice to three times more intense than the witness yolk. The same amount of green algae caused a more pleasent aspect of the chicken meat and a darker coloration of the legs. The taste and smell of the meat and of the eggs was not affected at all by the algae.
