“…LZM is an important effector molecule in the innate immunity of shrimp, which could attack the peptidoglycan in bacterial cell walls and prevent the invasion of harmful bacteria ( 43 ). It has been shown that the addition of MOS to fish diets can increase the activity of LZM ( 18 , 44 ). In line with the previous findings, dietary MOS enhanced the activity and gene expression of LZM in hepatopancreas.…”

“…The main beneficial effects of MOS were fish performance elevation by stimulation of the innate immune system and improvement of gut functions and nutrient digestibility, partly through reducing colonization of pathogen in the gastrointestinal tract (7)(8)(9)(10). The positive effects of MOS supplementation in aqua feed have been reported in various fish species such as rainbow trout (Oncorhynchus mykiss) (11,12), channel catfish (Ictalurus punctatus) (13), turbot (Scophthalmus maximus L.) (14), European sea bass (Dicentrarchus labrax) (15)(16)(17), and hybrid grouper (Epinephelus lanceolatus ♂ × Epinephelus fuscoguttatus ♀) (18). Studies on shrimp have shown that the addition of MOS in diets was conducive to weight gain, immunity (1,(19)(20)(21), and digestive enzyme activity (22).…”

This study was conducted to comprehensively investigate the beneficial effects of a mannan oligosaccharide product (hereinafter called MOS) on Litopenaeus vannamei and optimum level of MOS. Five isonitrogenous and isolipid diets were formulated by adding 0%, 0.02%, 0.04%, 0.08%, and 0.16% MOS in the basal diet. Each diet was randomly fed to one group with four replicates of shrimp in an 8-week feeding trial. The results showed that dietary MOS improved the growth performance and the ability of digestion of shrimp. Dietary MOS significantly increased the activity of total superoxide dismutase, catalase, and glutathione peroxidase and decreased the content of malondialdehyde in plasma of shrimp. Dietary MOS significantly increased the activity of alkaline phosphatase and lysozyme in plasma and the hemocyte counts. Dietary MOS significantly upregulated the expression of Toll, lysozyme, anti-lipopolysaccharide factor, Crustin, and heat shock protein 70 in the hepatopancreas. And dietary MOS significantly upregulated the expression of intestinal mucin-2, mucin-5B, and mucin-19, while it decreased the expression of intestinal mucin-1 and macrophage migration inhibitory factor. Dietary MOS improved the bacterial diversity; increased the abundance of Lactobacillus, Bifidobacterium, Blautia, and Pseudoalteromonas; and decreased the abundance of Vibrio in the intestine. Shrimp fed MOS diets showed lower mortality after being challenged by Vibrio parahaemolyticus. Notably, this study found a decrease in antibiotic resistance genes and mobile genetic elements after MOS supplementation for the first time. The present results showed that diet with MOS supplementation enhanced the organismal antioxidant capacity and immunity, improved intestinal immunity, optimized intestinal microecology, mitigated the degree of antibiotic resistance, and increased the resistance to V. parahaemolyticus in L. vannamei, especially when supplemented at 0.08% and 0.16%.

Background Mannan oligosaccharides (MOS) are a promising feed additive in animal husbandry due to mainly improving animal health status. The purpose of this study was to investigate the effects of MOS on growth performance, nutrient digestibility, ruminal fermentation, and twelve hematological parameters in sheep. Methods Ninety-six healthy Hu rams with similar body weights were chosen and divided into four treatment groups (twenty-four rams in each group), in which four different doses of MOS were tested: 0%, 0.8%, 1.6% and 2.4% of the basal diet (on an as-fed basis). Results The results showed that supplementation dietary MOS did not affect feed intake, body weight, average daily weight gain, or ruminal short-chain fatty acids (SCFAs) concentration; the ratio of individual fatty acids to total SCFAs, the C2/C3 ratio, and the hematological parameters in the sheep were also unaltered (P > 0.05). Conversely, supplementation dietary MOS increased the dry matter, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, and ash apparent digestibility (P < 0.05), and decreased the ruminal ammonia concentration in the sheep (P < 0.05), especially at a dose of 1.6%. Conclusions This indicates that supplementation dietary MOS improved nutrient utilization by the sheep and nitrogen metabolism in the rumen; however, the effects are too slight to interfere with the basal metabolism in the sheep.

Betaine plays some important roles in feed utilization and fish metabolism. The aim of this study was to evaluate the effect of dietary betaine supplementation on the growth performance and feed utilizationin hybrid grouper (Epinephelus lanceolatus♂ × Epinephelus fuscoguttatus♀). A completely randomized experimental design with four dietary levels of betaine, i.e.0.0%, 0.5%, 1.0%, and 2.0% in quadruplicate was done.Hybrid grouper juvenile obtained from Brackishwater Aquaculture Development Center, Situbondo, with an initial body length and body weight of 5.89 ± 0.05 cm and 2.86 ± 0.09 g, respectively was used as the tested animal. The fish was maintained in 60 cm x 40 cm x 40 cm aquaria with 75 L working capacity with individual recirculating system with a fish density of 15 fish/aquarium for 50 days. Experimental diet was provided to apparent satiation twice a day. The results of this study demonstrated that dietary betaine at a level of 0.5% resulted in higher feed utilization efficiency, protein and methionine retentions, and growth performance and lower ammonia excretion than those of the control (P<0.05). Higher antioxidative status was indicated by the lower malondialdehyde (MDA) in the liver of fish fed with betaine supplemented diets at levels of 1 - 2%. In conclusion, betaine supplementation of 0.5% could increase feed utilization efficiency and growth performance of hybdrid grouper. Keywods: Betaine, Hybrid Grouper, Growth Performance, Feed, Antioxidative Status ABSTRAK Betain memegang beberapa peranan penting dalam pemanfaatan pakan dan metabolisme pada ikan. Penelitian ini bertujuan untuk mengevaluasi pengaruh suplementasi betain pada pakan terhadap kinerja pertumbuhan dan pemanfaatan pakan pada juvenil ikan kerapu hybrid cantang (Epinephelus lanceolatus♂ × Epinephelus fuscoguttatus♀). Penelitian menggunakan rancangan acak lengkap dengan empat perlakuan pakan dengan tingkat suplementasi betain yang berbeda, yaitu 0.0%, 0.5%, 1.0%, dan 2.0% dengan empat ulangan. Juvenil ikan kerapu cantang yang berasal dari Balai Pengembangan Budidaya Laut Situbondo dengan panjang dan bobot awal masing-masing 5.89 ± 0.05 cm and 2.86 ± 0.09 g digunakan sebagai hewan uji dalam penelitian ini. Ikan dipelihara dalam akuarium berukuran 60 cm x 40 cm x 40 cm dengan kapasitas 75L yang dilengkapi dengan sistem resirkulasi individu dengan kepadatan 15 ekor per akuarium selama 50 hari. Pakan uji diberikan hingga sekenyangnya dua kali sehari. Hasil penelitian ini menunjukkan bahwa suplementasi betain sebanyak 0.5% menghasilkan pemanfaatan pakan, retensi protein, retensi metionina, kinerja pertumbuhan dan ekskresi ammonia yang lebih baik daripada kontrol (P<0.05). Status antioksidasi yang lebih juga yang ditunjukkan dengan lebih rendahnya konsentrasi malondialdehid (MDA) pada hati ikan yang diberi pakan dengan suplementasi 1-2% betain. Berdasarkan hasil penelitian dapat disimpulkan bahwa suplementasi betain sebanyak 0.5% dapat meningkatkan efisiensi pemanfaatan pakan dan kinerja pertumbuhan ikan kerapu cantang.
