Transcriptomic Changes in Broiler Chicken Hypothalamus during Growth and Development

Table 1

Traits of investigated cockerels estimated after slaughtering (mean ± SD).

Trait	Group of Ross 308 cockerels
	0-week-old; (1-day-old)	3-week-old; (22-day-old)	6-week-old; (45-day-old)
Body weight (g)	43 ± 5.3	1213 ± 104.7	3532 ± 386.9
Growth rate (%)		Days 0–22, 185.45%	Days 23–45, 97.3%
Average daily gain (g)		21 days, 83 ± 7.93	42 days, 114.3 ± 18.1
Abdominal fat (%)	0.05 ± 0.04	0.73 ± 0.28	0.90 ± 0.23
Breast muscles (%)	1.53 ± 0.25	17.93 ± 1.17	24.70 ± 1.87
Leg muscles (%)	9.90 ± 0.82	5.53 ± 0.72	16.50 ± 1.30

^A,B,CValues in rows with different letters show significant results (). Growth rate (%) was calculated using the following formula: , with BW_i as the initial body weight of the rearing period (g) and BW_f as the final body weight of the rearing period (g). Percentage of breast muscles, leg muscles, and abdominal fat of carcass was calculated in relation to the weight of the chilled carcass with giblets. ADG was measured as (BW on 21^st day − BW on 14^th day)/7 and (BW on 42^nd day − BW on 35^th day)/7.
