“…Moreover, the lambs fed with either Porphyra or soybean diet had similar ADG, showing that Porphyra sp. can replace soybean and provide the diet with an identical high-quality protein (Lind et al, 2020). Considering green seaweeds, to date, no effects on growth performance have been reported in ruminants for any specific seaweed.…”

The effects of dietary macroalgae, or seaweeds, on growth performance and meat quality of livestock animal species are here reviewed. Macroalgae are classified into Phaeophyceae (brown algae), Rhodophyceae (red algae) and Chlorophyceae (green algae).The most common macroalga genera used as livestock feedstuffs are: Ascophyllum, Laminaria and Undaria for brown algae; Ulva, Codium and Cladophora for green algae;and Pyropia, Chondrus and Palmaria for red algae. Macroalgae are rich in many nutrients, including bioactive compounds, such as soluble polysaccharides, with some species being good sources of n-3 and n-6 polyunsaturated fatty acids. To date, the incorporation of macroalgae in livestock animal diets was shown to improve growth and meat quality, depending on the alga species, dietary level and animal growth stage.Generally, Ascophyllum nodosum can increase average daily gain (ADG) in ruminant and pig mostly due to its prebiotic activity in animal's gut. A. nodosum also enhances marbling score, colour uniformity and redness, and can decrease saturated fatty acids in ruminant meats. Laminaria sp., mainly Laminaria digitata, increases ADG and feed efficiency, and improves the antioxidant potential of pork. Ulva sp., and its mixture with Codium sp., was shown to improve poultry growth at up to 10% feed. Therefore, seaweeds are promising sustainable alternatives to corn and soybean as feed ingredients, thus attenuating the current competition among food-feed-biofuel industries.In addition, macroalgae can hinder eutrophication and participate in bioremediation.However, some challenges need to be overcome, such as the development of largescale and cost-effective algae production methods and the improvement of algae digestibility by monogastric animals. The dietary inclusion of Carbohydrate-Active enZymes (CAZymes) could allow for the degradation of recalcitrant macroalga cell walls, with an increase of nutrients bioavailability. Overall, the use of macroalgae as feedstuffs is a promising strategy for the development of a more sustainable livestock production.

“…Compared with diets including white clover silage or soybean meal, inclusion of Porphyra spp. did not change the enteric CH 4 emissions [ 44 ]. The greatest CH 4 mitigation potential was observed for the red seaweed A. taxiformis with almost complete inhibition in vitro with inclusion levels up to 16.7% of the organic matter (OM).…”

“…The results showed that protein digestibility of the diets including S. latissimi were lower than those of Porphyra spp. The protein digestibility of Porphyra , both in vitro [ 66 ] and in vivo [ 44 ], was comparable to that of soybean meal. Lind et al [ 44 ] showed that there was no difference in the growth rate of lambs when fed either soybean meal or Porphyra spp.…”

Seaweeds contain a myriad of nutrients and bioactives including proteins, carbohydrates and to a lesser extent lipids as well as small molecules including peptides, saponins, alkaloids and pigments. The bioactive bromoform found in the red seaweed Asparagopsis taxiformis has been identified as an agent that can reduce enteric CH4 production from livestock significantly. However, sustainable supply of this seaweed is a problem and there are some concerns over its sustainable production and potential negative environmental impacts on the ozone layer and the health impacts of bromoform. This review collates information on seaweeds and seaweed bioactives and the documented impact on CH4 emissions in vitro and in vivo as well as associated environmental, economic and health impacts.

“…Therefore, the inclusion rate of SW was reduced to 2% of DMI, which showed no palatability issues, however, also resulted in no anti-methanogenic activity. Lind et al. (2020) encountered a similar issue when feeding a red seaweed at 10% of daily DMI.…”

Research into the potential use of various dietary feed supplements to reduce methane (CH4) production from ruminants has proliferated in recent years. In this study, two 8-week long experiments were conducted with mature ewes and incorporated the use of a variety of natural dietary feed supplements offered either independently or in combination. Both experiments followed a randomised complete block design. Ewes were offered a basal diet in the form of ad libitum access to grass silage supplemented with 0.5 kg concentrates/ewe/day. The entire daily dietary concentrate allocation, incorporating the respective feed supplement, was offered each morning, and this was followed by the daily silage allocation. In experiment 1, the experimental diets contained, 1) no supplementation (CON), 2) Ascophyllum nodosum (SW), 3) A. nodosum extract (EX1), 4) a blend of garlic and citrus extracts (GAR) and 5) a blend of essential oils (EO). In experiment 2, the experimental diets contained, 1) no supplementation (CON), 2) A. nodosum extract (EX2), 3) soya oil (SO) and 4) a combination of EX2 and SO (EXSO). Twenty ewes per treatment were individually housed during both experiments. Methane was measured using portable accumulation chambers. Rumen fluid was collected at the end of both experiments for subsequent volatile fatty acid (VFA) and ammonia analyses. Data were analysed using mixed models ANOVA (PROC MIXED, SAS v9.4.). Statistically significant differences between treatment means were considered when P < 0.05. Dry matter intake was not affected by diet in either experiment (P > 0.05). Ewes offered EO tended to have increased feed:gain ratio relative to CON (P < 0.10) and SO tended to increase average daily gain (P < 0.10) which resulted in animals having a higher final body weight (P < 0.05) than CON. Ewes offered EX1 and SO emitted 9% less CH4 g/day than CON. The only dietary treatment to have an effect on rumen fermentation variables relative to CON was SW, which enhanced total VFA production (P < 0.05). In conclusion, the A. nodosum extract had inconsistent results on CH4 emissions whereby EX1 reduced CH4 g/d while EX2 had no mitigating effect on CH4 production, likely due to the differences in PT content reported for EX1 and EX2. Soya oil was the only dietary feed supplement assessed in the current study that enhanced animal performance whilst mitigating daily CH4 production.
