Poultry Feed
The limiting growth factor in poultry feed is protein.
Spirulina (Arthrospira platensis) is a complete feed high in protein (50 to 65% link), vitamin B1 and B6, and may contain up to 14% lipids (of dry mass).link
Protein from organically produced Spirulina algae can fully replace protein from traditional organic sources in broiler diets. link
The higher the consumed Spirulina amount per bird in the starter and fattening period, the better the carcass weights and yield.link
Diets containing algae resulted in higher digestible methionine values compared to the 0% algae diet. link
In poultry, Spirulina reduces heat-stress induced release of stress hormones. link
Egg yolk colour has been found to intensify linearly with increased dietary Spirulina levels. link

Testing the digestibility of Spirulina in broiler chicken diets, the Spirulina ileal digestibility coefficients were 0.80 +/- 0.04 and 0.78 +/- 0.04 for essential and non-essential amino acids, respectively.
Protein was 514.7g per 888g dry matter (60%), 18.42 MJ/kg gross energy, 3.1 g/kg Calcium and 11.0 g/kg Phosphorus. link



Quail Feed
In Quails, four levels of Spirulina platensis microalgae (0%, 5%, 10%, and 15%) in the diets had positive effects on egg quality; increasing monounsaturated fatty acid levels and antioxidants in egg yolks, consequently reducing lipid peroxidation. link



Flamingo Feed
Flamingos feed by filtering spirulina from the water with their bill. Feeding experiments with caged birds (the lesser flamingo; Phoeniconaias minor) gave a clearing rate of 31.8 +/- 1.3 l/h for an adult flamingo, and a feeding rate of 5.6 g DW/h (dry weight per hour). The mean feeding time was 12.5 hours per day. (feeding rate of 66 g DW for the average bird) link



Lamb Feed
The ability of ruminants to digest raw spirulina (link) makes them especially suited to Spirulina microfarming.
High Spirulina supplementation level results in a decrease in intramuscular fat content in Australian purebred and crossbred sheep. link Medium supplemented lambs have highest liveweights. High Spirulina supplementation increases overall dietary energy intake and serum glucose levels.link Pregnant ewes receiving Spirulina deliver heavier lambs (up 4.07%) link
Sheep receiving dietary Spirulina levels of 20% did not significantly differ in liveweight compared to the control group (0%). link Supplementary spirulina does not compromise wool quality in supplemented weaner lambs link, and does not negatively impact lamb health and productivity.link



Swine Feed
In swines, supplemental Spirulina leads to higher growth rates, higher carcass outputt, and lower intramuscular fat. link
Spirulina administration around weaning alleviates diarrhoea in weaned piglets. link
The dietary substitution of soybean meal by Spirulina does not compromise pork quality. link


Cattle Feed
Cattle consuming pastures low in protein may also benefit from spirulina supplementation. link
