Abstract

The effects of genetic, physiological, and environmental factors(temperature, and type of watering system) on growth factors, accumulation of abdominal fat(AF), and the association between growth factors and AF of broilers and Athens-Canadian Randombred (ACRB) were studied in a series of nine trials. The final BW(6 or 7 wk) and 4-6 or 5-7 wk gain (G) were greater in groups raised at 21.1˚C than 26.7˚C. There was no consistent effects of environmental temperature on feed conversion ratio (FCR) although the FCR was significantly (P$\leq$.o5) reduced in 21. 1˚C group compared with the 26.7˚C group in two of six trials. The overall mean weight of AF relative to BW at 43 or 50 days of age were not significantly different between temperature groups: the means of AF of 21.1˚C and 26.7˚C groups were 1.81 and 1.78%, respectively. Environmental temperature had no consistent effect on the relationship between 4-6 or 5-7 wk C and 43 or 50 days AF, and 4-6 wk FCR and 43-days AF ; however, the association of 50 days AF with 5-7 wk FCR was highly significant in both temperature groups. The overall mean of correlation coefficient between FCR and AF was very low (r=.107). The waterer types did not significantly affect the AF. Generally, the effect of sex on the relationship between G and AF was not consistent in both sex groups. However, the association of AF with G was much greater in ACRB group compared with broiler group. The initial body weights (4 or S wk) was significantly (P$\leq$.001) correlated with AF in ACRB group, but not in the broiler groups. The effect of sire on AF was very high(P$\leq$.0001) in five of six trials.
