“…In another experiments with small ruminants, it was concluded that the macroalgae Laminaria digitata and Laminaria hyperborean could be used as alternative feed resources based on the high organic matter content, digestibility, and rumen dry matter degradability of these macroalgal species (77) . However, it was found that the macroalgae Ruppia maritima and Chaetomorpha linum, when incorporated at a concentration of 20% in barley and soybean meal, had no significant effect on feed intake, average daily weight gain, nutrient digestibility and nitrogen balance in lambs (75) .…”

“…There is also a recognized need for alternatives to soy and animal derived protein sources for use in animal nutrition and by 2050 it is predicted that we will need to nearly double food production to feed the world population (71) . performance (74,75) . For example, supplementation of the brown seaweed Ascophyllum nodosum to feedlot cattle was found to reduce faecal shedding of E. coli (4) .…”

Cereal and plant proteins are used frequently in the manufacture of animal, fish and human food products but are often deficient in essential amino acids. In contrast, macroalgal proteins contain all the essential amino acids and are a rich source of other bioactives including taurine, lipids, carotenoids and pigments. Furthermore, macroalgal proteins are a substrate for bioactive peptides generation. This paper discusses macroalgal bioactives and their potential use in fish, animal and human nutrition and health. Issues including their safe use, sustainability of supply, efficient drying and processing methods and novel extraction technologies are discussed as well as legislation issues.

“…It presents low protein degradability (40%) and a moderate energy digestibility (60%), being comparable to a medium to low quality forage and suitable to use with feeds that have high energy/low protein content as cereal grains [119]. Chaetomorpha linum (Chlorophyta) was also used to feed growing lambs, with a 20% seaweed meal, having a slightly depressing effect on growth and feed conversion ratio, possibly due to the high ash content [9,120].…”

Seaweed (known as marine algae) has a tradition of being part of the animal feed in the coastal areas, from ancient times. Seaweeds, are mixed with animal feed, because when consumed alone can have negative impact on animals. Thus, seaweeds are very rich in useful metabolites (pigments, carotenoids, phlorotannins, polyunsaturated fatty acids, agar, alginate and carrageenan) and minerals (iodine, zinc, sodium, calcium, manganese, iron, selenium), being considered as a natural source of additives that can substitute the antibiotic usage in various animals. In this review, we describe the nutritional values of seaweeds and the seaweed effects in the seaweed-based animal feed/supplements.

“…Macroalgae are economically important providing biomass for human foods, phycocolloids and animal feed [17] , [18] . They are rich in primary metabolites essential to metabolic function as minerals, vitamins, proteins, lipids and polysaccharides that can be used to improve basal feed quality [18] , [19] , [20] , [21] . The use of macroalgae in livestock feeds can increase growth rates and feed conversion efficiency in ruminants [19] and reduce enteric CH 4 production [22] , [23] .…”

Effects of Marine and Freshwater Macroalgae on In Vitro Total Gas and Methane Production

This study aimed to evaluate the effects of twenty species of tropical macroalgae on in vitro fermentation parameters, total gas production (TGP) and methane (CH4) production when incubated in rumen fluid from cattle fed a low quality roughage diet. Primary biochemical parameters of macroalgae were characterized and included proximate, elemental, and fatty acid (FAME) analysis. Macroalgae and the control, decorticated cottonseed meal (DCS), were incubated in vitro for 72 h, where gas production was continuously monitored. Post-fermentation parameters, including CH4 production, pH, ammonia, apparent organic matter degradability (OMd), and volatile fatty acid (VFA) concentrations were measured. All species of macroalgae had lower TGP and CH4 production than DCS. Dictyota and Asparagopsis had the strongest effects, inhibiting TGP by 53.2% and 61.8%, and CH4 production by 92.2% and 98.9% after 72 h, respectively. Both species also resulted in the lowest total VFA concentration, and the highest molar concentration of propionate among all species analysed, indicating that anaerobic fermentation was affected. Overall, there were no strong relationships between TGP or CH4 production and the >70 biochemical parameters analysed. However, zinc concentrations >0.10 g.kg−1 may potentially interact with other biochemical components to influence TGP and CH4 production. The lack of relationship between the primary biochemistry of species and gas parameters suggests that significant decreases in TGP and CH4 production are associated with secondary metabolites produced by effective macroalgae. The most effective species, Asparagopsis, offers the most promising alternative for mitigation of enteric CH4 emissions.
