Abstract

The present study aimed to evaluate the impact of fermented meat processing wastewater protein hydrolysate (FWMPH) prepared by Pediococcus lolii fermentation as an alternative protein source on growth performance, serum biochemistry, and hematological parameters of broiler chicks. FWMPH exhibited antioxidant, anti-angiotensin converting enzyme (ACE), and antimicrobial properties. A total of 60 one-day-old Vencobb broiler chicks were divided into fve dietary groups on day 8 and a feeding trial was performed for 48 days. Diets were prepared by replacing soya protein concentrate (SPC) at diferent levels of FWMPH as the protein source. These diets were denoted as SPSD (100% SPC), FMP-25 (25% FWMPH +75% SPC), FMP-50 (50% FWMPH+50% SPC), FMP-75 (75% FWMPH+25% SPC), and FMP-100 (100% FWMPH). FMP-25 and FMP-100 diet group broiler chicks showed the highest and lowest feed consumption (P<0.05), respectively. However, the highest body weight gain (1506.08±52.52 g) was observed in FMP-75 diet-fed chicks (P<0.05). Furthermore, FMP-75 chicks displayed better feed conversion ratio (1.96), feed efciency ratio (0.51), and protein efciency ratio (2.32) values than other diet group chicks (P<0.05), implying that the FMP-75 diet had better efect on the broiler growth. Also, the FMP-75 diet chicks showed better hematological values, serum biochemical parameters revealed no negative efect upon FWMPH consumption, and no pathological signs were observed in the histopathological examination as compared to the SPSD diet group (P<0.05). Hence, the results could be helpful in the application of FWMPH at 75% level in the poultry feed as a potential protein ingredient in the countries looking for local feed protein products as soya bean meal replacement.
