EFFECTS OF α-KETOGLUTARATE SUPPLEMENTATION IN LOWPHOSPHOROUS DIETS ON GROWTH PERFORMANCE, BODY COMPOSITION AND SERUM BIOCHEMICAL INDEXES OF SONGPU MIRROR CARP
To study the effects of α-ketoglutarate(AKG) supplementation in low-phosphorous diets on growth performance, body composition and serum biochemical indexes of Songpu mirror carp, triplicate groups of Songpu mirror carp(6.67±0.84) g were fed with practical diets containing available P(AP) 0.73%(normal P) and 0.47%(low-P) with graded levels of 0, 0.4%, 0.8%, 1.2%, 1.6% and 2.0% of AKG to satiation for 8 weeks, respectively. The results showed that the feed coefficient(FCR) of the low phosphorus group was sign...
