Abstract: A 6-week trial was conducted to investigate the effects of animal skin protein sources from swine and cattle on growth performance, body condition and blood characteristics in growing pigs. A total of 96 pigs (23.50 ± 0.61 kg) were randomly allotted into four dietary treatment groups as follows: (1) basal diet (BD); (2) basal diet with 1.5% hydrolysed render meal (HRM); (3) basal diet with 1.5% swine skin meal (SSM); (4) basal diet with 1.5% cattle hide meal (CHM). There were six replicate pens per treatment with four pigs per pen. The average daily gain (ADG) was improved in response to SSM treatment compared with other treatments (P < 0.05). Pigs fed with HRM, SSM and CHM diets showed increases in average daily feed intake (ADFI) and decreased gain-to-feed (G : F) ratios compared with pigs fed with BD (P < 0.05). There were no differences in dry matter (DM), nitrogen (N), and energy (E) digestibility among treatments. The backfat thickness and lean percentage of pigs was unaffected by the treatments. Similarly, there was no difference in blood characteristics among treatments. In conclusion, the supplementation of SSM in growing pig diets improved the growth rate and Feed Intake (FI), but its usage in swine diets is limited by the poor protein quality.
