Changes in the Neuropeptide Y mRNA Expression in Oncorhynchus mykiss at Different Feeding Frequencies

Table 3

Growth performance, FCR, and survival rate of Oncorhynchus mykiss fed with the different feed frequencies after 31 days ( values of six replicates ()).

	Feed frequency
	T1	T2	T3
IW (g)
FW (g)	^a	^b	^b
PWG (%)	^a	^b	^ab
DWG (g/fish)	^a	^b	^b
SGR (%)	^a	^b	^b
VSI (%)	^a	^b	^ab
FI (g)
FCR	^b	^a	^a
Survival rate (%)	^b	^a	^ab

IW: initial weight; FW: final weight; PWG: percentage weight gain; DWG: daily weight gain; SGR: specific growth rate; VSI: viscerosomatic index; FI: feed intake; FCR: feed conversion ratio; T1: fed once a day at 09:00; T2: fed thrice a day at 09:00, 13:00, and 17:00; T3: fed five times a day at 09:00, 11:00, 13:00, 15:00, and 17:00. A different superscript in the same row denotes statistically significant differences ().
