Effect of dried Chlorella vulgaris and Chlorella growth factor on growth performance, meat qualities and humoral immune responses in broiler chickens

Abstract

This experiment was carried out to investigate the effects of dried chlorella powder (Chlorella vulgaris; DCP) and chlorella growth factor (CGF) on growth performance, serum characteristics, meat qualities and humoral immune responses in broiler chicks. A total of 1050 day-old Ross male broiler chicks were randomly divided into 35 pens (30 chicks/pen) and subjected to one of seven dietary treatments. A non-medicated corn-soybean meal base diet was considered as negative control (NC) and added with either antibiotic (PC), three levels of DCP (NC diets added with 0.05, 0.15 or 0.5 % DCP) or two levels of CGF (NC diets added with 0.05 or 0.15 % CGF). The final body weight and daily weight gain in PC and groups fed diets with 0.15 or 0.5 % DCP were heavier (p < 0.001) than those of NC and CGF-treated groups. Serum total lipid concentrations were lower (p = 0.001) in groups fed diets with 0.5 % DCP and 0.05 or 0.15 % CGF compared with PC group. The levels of serum IgG (p = 0.050) and IgM (p = 0.010) were elevated in chicks fed diets with DCP and CGF compared with the PC or NC group. Meat qualities such as cooking loss, meat color, and pH, of edible meats were not altered by dietary treatments. Collectively, these results indicate that dietary DCP, but not CGF, exerted growth-promoting effect, and both DCP and CGF affected humoral immune response in broiler chicks.

Dietary supplementation effects of Chlorella vulgaris on performances, oxidative stress status and antioxidant enzymes activities of prepubertal New Zealand White rabbits

“…Similarly, in agreement with this present study, An et al (2016), also reported that supplementation of dried Chlorella vulgaris powder not only significantly increased growth rates, but also increase final weight gain in broilers chicken compared with control unsupplemented group. The agreement between this report and the outcomes of this study indicated that absorptive efficiency of feed significantly improved in the rabbit which is also a caeca fermenter like chicken.…”

Efficacy of Chlorella pyrenoidosa to Ameliorate the Hepatotoxic Effects of Aflatoxin B1 in Broiler Chickens

“…It is documented that dietary supplementation of chlorella improved growth performance, affected intestinal microbial diversity and modulated immune responses (Janczyk et al, 2009). Later on, it was found that C. vulgaris induced growth promoting effects and positively affect the humoral immune response in broiler chicks (An et al, 2016). To the best of our knowledge, it is the first study on the effects of dietary supplementation of Chlorella pyrenoidosa against AFB1 on growth performance, serum biochemical parameters, antioxidant capacity and lipid peroxidation in liver of broiler chickens.…”

Applications of microalga Chlorella vulgaris in aquaculture

“…Chlorella vulgaris contains a beneficial phytonutrient called Chlorella growth factor (CGF), which is rich in nucleic acid associated substances such as peptides, proteins, amino acids, vitamins and vital sugars (An et al . ). Different studies have reported vibrant nutritional effects of C. vulgaris at varying supplementation levels in aquaculture feeds (Table ).…”
