The Requirement and Protective Effects of Dietary Protein against Chronic Ammonia Exposure in Juvenile Genetically Improved Farmed Tilapia (Oreochromis niloticus)

Table 4

Whole-body proximate composition (wet weigh basis) of GIFT juveniles fed diets with different protein levels under low or high ammonia exposure for 8 weeks.

Ammonia (mg/L)	Protein level (%)	Moisture (%)	Crude protein (%)	Crude lipid (%)	Ash (%)
0.02 mg/L	31.04	^a	^ab	^c	^cd
0.88 mg/L	22.64	^a	^a	^c	^a
	27.26	^ab	^ab	^bc	^ab
	31.04	^ab	^abc	^abc	^ab
	35.63	^abc	^abc	^ab	^bc
	38.47	^bc	^bc	^a	^a
	42.66	^c	^c	^a	^a

Values are (standard deviation) of three replicate per treatment, values in the same row within the same protein level sharing different letters are significantly different at , as determined by Tukey’s test.
