The objective of this research was to investigate the effect of substituting fish meal with dried
porcine placenta (DPP) on the growth performance in post-weaning pigs. The experimental animals
included 25 males and 25 females. The initial age was approximately 6 wk and the experiment lasted 21
days. Animals fed without DPP acted as the control group, treatment 1 (DPP1), treatment 2 (DPP2),
treatment 3 (DPP3) involved substituting fish meal with 40, 60 and 80 % DPP, respectively, while
treatment 4 (DPP4) involved entirely substituting fish meal with DPP. Animals in the DPP3 group had
the highest final weight and average daily gain (31.15 ± 2.90 kg and 0.69 ± 0.14 kg/head/day). In
addition, the feed conversion ratio of the animals in the DPP3 group was the lowest (1.45 ± 0.29). This
result indicated that DPP is an effective alternative protein source for swine feed since it significantly
improved growth performance. However, substituting fish meal with 100 % DPP would not be a good
choice for increased growth performance. In future studies, more research should examine in depth other
important traits such as immune traits or growth traits in other periods. Furthermore, processing cost and
operating cost of DPP should be considered for sustainable economic efficiency.
