This study was carried out to determine the effect of dietary seaweed (Ulva lactuca) supplementation on growth performance of sheep, in vitro gas production, estimated energy, and microbial protein synthesis. A total of 18 Naimey male sheep with average live weight of 22.78 ± 0.24 kg were randomly allocated to 3 groups. Sheep in group 1 were fed a diet containing commercial feed without seaweed as a control diet, sheep in group 2 were fed the control diet with 3% seaweed, and sheep in group 3 were fed the control diet with 5% seaweed. The supplementation of seaweed had no effect (P > 0.05) on the average daily gain, feed intake, and feed conversion efficiency. The extent of gas production at 72 h was similar among the 3 groups (P > 0.05). There were no significant differences (P > 0.05) in the potential degradability, gas production rate, metabolizable energy, net energy, organic matter digestibility, and microbial protein synthesis among the experimental diets. This study concluded that dietary supplementation of seaweed (Ulva lactuca) has no effect on growth of sheep, in vitro gas production, potential degradability, estimated energy, organic matter digestibility, and microbial protein synthesis.

“…Norris species is characterized as a robust plant (Rhodophyta, Ceramiales, Rhodomelaceae), which can measure from 10 to 15 cm in height, with flat apices of 3 to 4 mm wide, showing dark red coloration (Carvalho et al, 2006). Several biological activities have been described from O. obtusiloba, mainly for their extracts, such as the fraction of O. obtusiloba rich in lectin that inhibited the trypsin and α-amylase enzymes, indicating its potential use in the production of drugs against diabetes (de Oliveira et al, 2009) or the ethanol extract that was able to inhibit the replication of Zika virus while maintaining low cytotoxicity (CC 50 =525 µg/ml) (Cirne-Santos et al, 2017). Antiviral activity against HSV-1 and HSV-2 has also been described for glycolipids extracted from O. obtusiloba (de Souza et al, 2012).…”

The genus Osmundaria (Rhodophyta, Ceramilaes, Rhodomelaceae) comprises tropical and temperate regions red marine seaweeds species. Osmundaria obtusiloba is distributed from the northeastern coast of Brazil to the state of Rio de Janeiro. Studies with ethanol extract of red seaweed O. obtusiloba showed the antiviral potential of this alga. Hence, this study examined in BALB/c mice the acute toxicity after oral administration of O. obtusiloba crude extract. Then, female BALB/c mice received a single dose of O. obtusiloba extract by gavage at 550 mg/kg and their behaviors were monitored for a 14 day period. The biochemical and histological changes in the liver, kidney, stomach and spleen were analyzed. O. obtusiloba extract did not significantly change behavior, body weight, hematological or biochemical profiles. The organs of the animals did not show significant alterations when submitted to treatment with O. obtusiloba extract. In conclusion, the in vivo results revealed that O. obtusiloba has low toxicity and it can be and may be the target of further studies of biological activity.

“…Η θρεπτική αξία των φυκιών εξαρτάται από το μέγεθος τους, την πεπτικότητά τους, την παραγωγή τοξικών ουσιών και τη χημική τους σύσταση (Becker 1994). Αν και μεταξύ όλων των φυκιών υπάρχουν διαφορές στη σύσταση, παρ' όλα αυτά αποτελούν αξιόλογη πηγή πρωτεϊνών, με περιεκτικότητα που κυμαίνεται σε υψηλά επίπεδα, 10-15% στα μακρο-φύκια (Oliveira et al 2009) και 28-71% στα μικροφύκια (Becker 1994). Εξάλλου, ο Becker (2007) αναφέρει ότι η περιεκτικότητα των πρωτεϊνών των φυκιών σε ορισμένα αμινοξέα (λυσίνη, μεθειονίνη, τρυπτοφάνη, θρεονίνη, βαλίνη, ιστιδίνη, ισολευκίνη) είναι συγκρί σιμη με εκείνη του αυγού ή των σπερμάτων σόγιας.…”

“…Σε ό,τι αφορά την περιεκτικότητα των φυκιών σε υδατάνθρακες βρέθηκε να είναι περίπου 60% (Jensen 1993, Oliveira et al 2009). Οι υδατάνθρακες αυτοί δεν πέπτονται στον πεπτικό σωλήνα του ανθρώπου, όμως η κατανάλωση τους σχετίζεται με ευεργετικά αποτελέσματα στην υγεία του ανθρώπου, π.χ.…”

Γενικά, η περιεκτικότητα των φυκιών σε κυτταρίνες είναι υψηλότερη σε σχέση με εκείνες των περισσότερων φρούτων και λαχανικών (Oliveira et al 2009). …”

In this review article the use of algae as feed in animal nutrition is being examined. The algae evolved on earth 3.5 billion years ago. They are primitive, generally aquatic and photosynthetic organisms, which range in size from 0,2-2,0 μιτι in diameter -microalgae (phytoplankton) up to 60 m length- macroalgae and may divide once or more per day. Algae are classified using a combination of characteristics in the chlorophyta, phaeophyta, chrysophyta, rhodophyta (all of them are macroalgae), pyrrhophyta and cyanophyta (they are microalgae). The chemical composition of algae varies over a wide range and depends on environmental conditions. Algae are necessary in the reduction of greenhouse gas emissions. They can be used as biodisel from their bio-lipid oil, as feed additives (alginates, carrageenans, agar, pigments), as therapeutic agents, as cosmetics, as organic fertilizer. Moreover, edible algae are considered sources of minerals and a complementary source of food protein for human -especially infunctional foods and animal nutrition, both in ruminants and monogastric animals. Algae in the rations of lactating cows increased milk production, the average milk protein, the amount of lactose, and prolonged the lactation period, while algae rich in (n-3) fatty acids effected positively on this fatty acid content of milk. In calves the dietary algae en-hanced immune function and improved carcass characteristics. Regarding the ewes, the algae nutrition affected milk fat composition and their dairy products. Researches on monogastric animals showed that the dietary supplementation of algae rich in docosqexaenoic acid increased its content in muscle tissue of rabbits, heavy pigs (live weight around 160 kg) and in the egg yolk of laying hens. In addition, algae in poultry diets can be used effectively as pigment sources both in egg yolk and in broiler skin and shanks. Algae have been found also to be a valuable food for fish farmed by acquaculture. However, further investigation is needed concerning the use of algae in human and animal nutrition.
