An 8-week feeding trial was conducted to evaluate the effects of dietary fermented rapeseed meal (FRM), potassium iodide, and their interactions on growth performance, approximate composition, antioxidant capacity in tilapia, Oreochromis niloticus (initial body weight: 3.50 ± 0.15 g). Six isonitrogenous isolipidic diets from a 2 × 3 factorial design were formulated with two levels FRM (25.8 51.6%) three iodide (0, 6, 12 mg/kg), respectively. The results indicated that iodine had no significant influence SR tilapia but exerted weight gain (WG), specific rate (SGR), feed intake (FI), hepatosomatic index, viscerosomatic index. WG, SGR, FI 51.6% groups significantly lower than those other (p < 0.05), inclusion diet enhanced 0.05).

Molting is a vital physiological process essential for the growth and development of Penaeus vannamei, with significant implications aquaculture productivity. This study aimed to identify neuropeptide-related genes involved in molting through transcriptomic analysis. RNA sequencing pre-molt post-molt samples revealed 1203 differentially expressed (DEGs). Functional enrichment analysis indicated that these play roles cuticle formation regulation. Among DEGs, 243 were predicted be neuropeptides based on presence signal peptides absence transmembrane domains. Five key neuropeptide genes-PvCHH, PvMIH, PvEH I, PvCDA II-were identified as critical regulators molting. Their role was further validated RT-qPCR analysis, confirming their close association process. These highlighted this pivotal factors driving P. vannamei. The research are anticipated offer valuable insights into regulation Additionally, synthetic products hold promise improving consistency shrimp aquaculture.

Unconventional protein feeds, characterized by low nutritional value, high variability, and poor palatability, have limited their application in swine production. Fermentation technology holds the key to addressing these shortcomings. Given ban on antibiotics China, inferior quality of imported pig breeds, long-term dependence soybean, prospects for fermented unconventional feeds are promising. This paper delves into common types factors influencing fermentation process, mechanisms which they enhance health, challenges offering theoretical insights future development feed industry.
