Astaxanthin as a Potential Antioxidant to Improve Health and Production Performance of Broiler Chicken

Table 1

Overview of recent application of astaxanthin in broiler chicken.

Animal	Dose rate	Major findings	References
Broiler	2.3–4.6 mg/kg in basal diet	Improved weight gain in the finisher period and linearly decreased feed conversion ratio in the finisher period	[8]
Broiler	50 mg/kg in basal diet	Improve in the average body weight and the weight increase and the amount of feed consumed, as well as an improvement in the food conversion rate	[2]
Broiler	10 and 20 mg/kg in basal diet	Improved T cell proliferation and IgG production	[13]
Broiler	Mixture of nanoselenium with astaxanthin at a concentration of 0.3 + 60 mg/kg	Increase body weight	[14]
Broiler	0.4% of histamine + 100 ppm of astaxanthin in basal diet	Astaxanthin did not affect histamine-dependent changes in chick body weight or weights of the gizzard and proventriculus	[12]
Broiler	40 or 80 mg/kg in basal diet	Decreased the hyperthermic stress level and improved meat quality, as well as antioxidant status of chickens exposed to heat stress	[15]
Broiler	Basal diet supplemented with 0.15% astaxanthin	Increased both the redness and yellowness of skeletal muscle and decreased the muscle MDA concentration	[16]
Broiler	Diet containing 100 ppm astaxanthin	Did not show anti-inflammatory effects in chickens	[17]
Broiler	10–80 mg/kg in basal diet	Affected the hepatic gene expression and protein production related to redox status, heat stress and inflammation, and lipid metabolism	[11]
Broiler	7.5% of shrimp waste flour in broiler diets	Improve carcass weight, carcass percentage, abdominal fat of broilers	[18]
Broiler	10 and 20% silage of rainbow trout in basal diet	Improve feed consumption, live weight gain, feed conversion index, mortality, carcass yield, economic conversion index, and economic profitability index	[19]
Broiler	2% of shellfish processing industry waste slurry in broiler diets	Improved body weight, weight gain, feed intake, and FCR	[20]
