Summary: The study found that the inclusion of soybean meal in the diet negatively affected the growth performance, digestive enzyme activity, and muscle growth-related gene expression in Litopenaeus vannamei. Increasing levels of dietary soybean meal led to decreased body weight, feed intake, intestinal trypsin and amylase activities.

Summary: The addition of probiotics improved growth performance and intestinal morphology, while substitution of some or all fish meal with fermented soybean meal promoted weight gain and digestion in bullfrogs. However, complete replacement of fish meal had negative effects on growth and digestion in bullfrogs.

Summary: This study investigated the potential of replacing soybean meal with corn gluten meal in the diet of Pacific white shrimp. The results showed that corn gluten meal significantly improved the growth performance of the shrimp and had positive effects on biochemical indices, histology, and intestinal flora.

Summary: Reducing antibiotic use and improving aquaculture efficiency are of great significance. In this study, Penaeus vannamei was fed with companion feeding using different concentrations of Bacillus subtilis. The results showed that adding 0.5% of B. subtilis to the feed had the best effect on growth performance. Analysis of intestinal flora revealed that the abundance of Proteobacteria and Firmicutes, as dominant phyla, had significant differences compared with the control group. The abundance of intestinal flora tended to increase as the concentration of probiotics increased.

Summary: Microencapsulation is an advanced technique that improves the viability of probiotics and reduces sensitivity during processing and storage. In a study on white shrimp, feeding encapsulated probiotics resulted in increased amplicon reads and alterations in the bacterial profile of the intestines, with the presence of beneficial genera. Therefore, encapsulated B. subtilis E20 is beneficial for the shrimp microbiota.

Summary: This study investigated the effects of Bacillus velezensis BV007 on the growth performance, immune responses, and intestine microbiota of Litopenaeus vannamei shrimp. The results showed that dietary supplementation of BV007 significantly improved growth performance, enhanced immune responses, and modulated the intestinal microbiota of shrimp by increasing beneficial bacteria (Bacillus) and reducing pathogenic bacteria (Vibrio) abundances. A dosage of 10(7) CFU/g feed was recommended for promoting the growth and health status of shrimp.

Summary: This study screened the proteolytic activity of Bacillus species in meat and bone meal and investigated the effects of fermented meat and bone meal-soybean meal products on the growth performance of broilers. The results showed that Bacillus subtilis M6 efficiently decomposed meat and bone meal-soybean meal and improved the protein properties and nutritional value of the product. Furthermore, supplementation with 5% fermented meat and bone meal-soybean meal products promoted weight gain in broilers.

Summary: The study evaluated the addition of mussel meal as a feed additive for whiteleg shrimp to improve growth and cold resistance. The results showed that adding 3% or 4% mussel meal had similar effects as the control group, while adding 1% or 2% mussel meal significantly improved final weight, weight gain, and relative growth rate, and reduced feed conversion ratio. Furthermore, there were no differences in thermal shock resistance and survival among the treatment groups.

Summary: This study demonstrates the use of genetically engineered probiotics to produce antiviral dsRNAs, which effectively induce the RNAi mechanism in shrimp hemocytes, enhancing antiviral capabilities and reducing viral load. Shrimp pre-treated with the engineered probiotics showed higher survival rates and significantly reduced viral loads when challenged with the virus.

Summary: The study aimed to analyze the mechanism of Chlorella sorokiniana meal replacing fish meal on the growth performance and immune function of Pacific white shrimp. It was found that low replacement of fish meal (20%) with Chlorella significantly improved the growth performance of the shrimp, possibly through activating the C-type lectin receptor signaling pathway to regulate immune function. However, high replacement (>60%) of fish meal with Chlorella reduced growth performance and immunity, potentially through affecting the lysosomal signaling pathway.

Summary: Soybean meal is an important source of plant-based protein in the livestock and poultry industry, but it contains anti-nutritional factors that can damage animal intestinal health. This study isolated a potential probiotic Bacillus licheniformis (B4) from camel feces, which exhibited phytase, protease, cellulase, and xylanase activities. B4 could tolerate low pH, bile salts, and high temperatures and effectively degrade anti-nutritional factors in soybean meal, enhancing its nutritional value.

Summary: This study aimed to select Bacillus strains with optimal keratin degradation ability for feather meal-soybean meal fermentation and investigate the effects of the fermented product on broiler growth performance. The results showed that Bacillus amyloliquefaciens CU33 produced the best fermented feather meal-soybean meal product (FFSMP) and 50-60% water content during fermentation was recommended. Diets supplemented with 5% FFSMP improved poultry growth and achieved similar results to fish meal.

Summary: This study investigated the effects of replacing dietary fish meal with enzyme-treated soybean (ETS) on the growth performance, intestine microflora, immune response and disease resistance of white shrimp. Results showed no significant impact on the survival rate and specific growth rate of shrimp, but the feed conversion ratio increased significantly with higher replacement levels. The levels of total anti-oxidative capacity and malondialdehyde in serum increased with replacement levels, while the activity of lysozyme in serum also increased with replacement levels from 8% to 40%.

Summary: The effect of partially substituting bovine by-product meal with poultry by-product meal in fish food for white shrimp was evaluated. It was found that the substitution improved the biological indices of the shrimp and resulted in better feed conversion efficiency and digestibility. However, further research on the effect of the substitution on lipid metabolism is recommended.
