Feeding reduced dietary protein added with prebiotics on protein metabolism characteristics and growth performance of broiler chickens

Abstract

The purpose of the present study was to evaluate the effect of feeding prebiotics on protein metabolism characteristics and growth performance of broilers. A completely randomized design with 4 treatments and 5 replications was arranged. Heterophil/lymphocyte (H/L) ratio, protein metabolism characteristics (protein digestibility, fecal Nt-MH excretion, and meat protein mass), and growth performances (feed consumption, BWG, and FCR) were the parameters observed. Analysis of variance was performed to statistically evaluate the data, and continued to Duncan test at 5% probability. Protein digestibility, and meat protein mass in T1 and T2 were significantly (P<0.05), while those in T0 were significantly (P<0.05). On the contrary, H/L ratio, feed consumpton, and FCR were significantly (P<0.05) lowest in both T1 and T2, but those in T0 were significantly (P<0.05). In conclusion, feeding inulin and soy-oligosaccharide extracts improves protein metabolism and it is characterized by the increase in protein digestibility and meat protein mass, and promote better growth of broiler.

Response of serum biochemical profile, antioxidant enzymes, and gut microbiota to dietary Hong-bailanshen supplementation in horses

“…The content of TG and CHO in serum can reflect the development and deposition of adipose tissue ( Sakakura et al, 2022 ). The contents of TP and ALB mainly reflect the body’s nutritional status and protein metabolism level ( Suthama et al, 2020 ). In our experiment, dietary HBLS decreased serum ALT, ALP, and CK activity, and the lowest value was detected on day 28 ( p < 0.05, p < 0.01) ( Figure 2 ).…”
