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 was evaluated in the present investigation.FWMPH exhibited antioxidant, anti-angiotensin converting enzyme (ACE), and antimicrobial properties. A total of 60 broiler chicks were divided into ve dietary groups on day 8 and a feeding trial was performed for 48-days. Different diets were prepared by replacing soya protein concentrate (SPC)with different levels of FWMPH as a 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, feed e ciency ratio, and protein e ciency ratio values than other diet group chicks (P < 0.05). The hematological, serum biochemical parameters and histopathological examination revealed that the chicks fed with FWMPH were not negatively affected by dietary treatments and were better than the SPSD diet group (P < 0.05). Hence, FWMPH at 75% level can be exploited as a potential protein ingredient as a substitute for soy protein in the broiler diet for better growth performance of the birds without deleterious effects.

FWMPH exhibited antioxidant, anti-angiotensin converting enzyme (ACE), and antimicrobial properties. A total of 60 broiler chicks were divided into five dietary groups on day 8 and a feeding trial was performed for 48-days. Different diets were prepared by replacing soya protein concentrate (SPC) with different levels of FWMPH as a 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, feed efficiency ratio, and protein efficiency ratio values than other diet group chicks (P < 0.05). The hematological, serum biochemical parameters and histopathological examination revealed that the chicks fed with FWMPH were not negatively affected by dietary treatments and were better than the SPSD diet group (P < 0.05).
