This study examined the impact of expanded black soldier fly (EP-BSF) meal on laying hens' reproductive hormones, gap junction proteins, cytokines, and performance. Over 12 weeks trail period, 400 Hy-Line brown hens procured at 24 age underwent a completely randomized design with 5 treatments, 8 replicates, 10 birds per replicate. The received control diet (CON) or diets 3 %, 6 9 % EP-BSF. Results demonstrated that lower EP-BSF levels showed linearly higher (p < 0.05) hen day egg production (HDEP) from 30 to 33 mass (EM) in cumulative comparable CON. Tendencies towards average weight (AEW) was observed when incorporated CON during 34-37 = 0.079), as well 0.056). Yolk color quadratically 0.024) 30-33 weeks, tendency 0.050) level increases. Albumin supplementation 26-29 0.062) weeks. Eggshell thickness increased increased. Serum estradiol (E2) were groups, correlating expression connexins GJA1 GJA4 oviductal tissues tumor necrosis factor-alpha (TNF-α). In conclusion, incorporation had similar HDEP, AEW, EM, albumin We attributed this E2 resulting TNF-α, GJA chicken oviduct. Our findings also strongly indicate estrogen plays role modulating connexins. These suggest layer may serve an alternative protein source for poultry feed.
