| Summary: | The purpose of this study was to evaluate effects of replacing soybean meal with
perilla seed meal (PSM) on growth performance, proximate composition of meat,
meat quality, and fatty acids composition of meat in broilers. A total of 60
one-day-old chicks of ROSS 308 (initial body weight of 44.8
± 0.4 g) were randomly allotted to four treatment groups (15 replicate
cages with 1 broilers per cage) in a period of 5 weeks. Dietary treatments
included control (CON) basal diet (corn-soybean meal-based diets) and test diets
in which PSM was included at 0.5% (T1), 1% (T2), or 2% (T3) to gradually replace
soybean meal. At the end of experiment, all broilers were slaughtered for
collecting breast and thigh meat. At 5 weeks, T2 and T3 treatment groups had
higher (p < 0.05) body weights than CON and T1 treatment
groups. Weight gain was increased (p < 0.05) in T2 and
T3 treatment groups. Feed intake was decreased (p <
0.05) in T3 treatment group. Broilers in T2 treatment group had lower
(p < 0.05) feed conversion ratio than those in other
treatment groups. In proximate composition of breast meat, there was no
significant (p > 0.05) difference in moisture and ash.
Fat composition of breast meat was significantly (p <
0.05) increased in T2 and T3 treatment groups. Regarding meat quality, broilers
fed T3 diet had higher (p < 0.05) water holding capacity
than those fed other diets. Regarding fatty acids composition of thigh meat,
broilers fed T3 diet had higher (p < 0.05) linolenic
acid than those fed other diets. In conclusion, soybean meal replaced by 2%
perilla seed meal in broiler diet can improve growth performance, meat quality,
and fatty acids composition of thigh meat in broilers. Perilla seed meal can be
a lot of potential alternatives feedstuff for soybean meal in this study. |
