Nutritive Value of Spirulina, Green Algae, for Poultry Feed

Replacement value of blue‐green alga(spirulina platensis)for fishmeal and a vitamin‐mineral premix for broiler chicks

“…More remarkable is the finding that complete replacement of fish meal with alga at 140 g/kg still gave satisfactory results, indicating that the quality of the Spirulina preparation in combination with groundnut protein was as good as that of the protein in the control diet. This result confirms the earlier findings of Yoshida and Hoshii (1980) who reported no growth depression up to 200 g/kg of Spirulina suggesting that the quality of the algal preparation may be an important factor influencing its dietary properties.…”

“…It has become obvious that the most suitable algal species for mass cultivation is probably the cyanobacterium (blue-green alga) Spirulina (Vonshak and Richmond, 1988;Henrikson, 1989). Some experiments have investigated the effects of feeding this organism to poultry (Blum and Calet, 1976;Yoshida and Hoshii, 1980;Ross and Dominy, 1990). In the framework of a detailed research programme on the mass production of Spirulina at this institute (CFTRI), studies were performed on the utilisation of Spirulina, grown in a synthetic medium, as a protein supplement in animal feeding.…”

Effects of diets with increasing levels of Spirulina platensis on the performance and apparent digestibility in growing rabbits

“…Yoshida and Hoshi (1980) and Becker and Venkataraman (1982) fed varying levels of spirulina to growing chickens with satisfactory results at the lower levels of 5 to 10%; growth was depressed at levels above 20%. The current study was conducted using SP inclusion levels of between 5 and 15%, because the low level used in pig trials by Grinstead et al (2000) showed inconsistent and minimal improvement in growth performance when the pigs were fed diets containing 0.2, 0.5 and 2% SP.…”

Improving the Dietary Protein Quality by Amino Acid Fortification with a High Inclusion Level of Micro Algae (<i>Spirulina platensis</i>) or Insect Meal (<i>Hermetia illucens</i>) in Meat Type Chicken Diets

“…Spirulina meal (SM) has been introduced as feed ingredient in poultry diets more than 20 years ago [10] [11]. It has already been demonstrated that Spirulina platensis can successfully be included in broiler diets [8] [9].…”
