“…The high immunity strengthened the anti-stress ability of the body (Zhang 2012); the stresses mainly included environmental stress, managerial stress, and immunological stress. There was a reduction in feed intake and a shift in the partitioning of dietary nutrients away from body fat/protein deposition and skeletal muscle accretion toward metabolic responses that supported the immune system when animals were under stress conditions (Johnson 1997).…”

The present experiment was conducted to study the effects of chitosan (CHI) on immune and antioxidative function in beef cattle. A total of 24 fattening Simmental cattle with similar body weight and age were divided randomly into three dietary groups, and the three diets contained 0, 500, and 1000 mg/kg CHI, respectively. The feeding trial lasted for 84 days. It was found that: (1) the addition of CHI in diets improved (P < 0.05) the levels of IgA and interleukin-1, and decreased (P < 0.1) the levels of soluble cluster of differentiation 4 receptor in serum at middle stage except that IgA remained unchanged in 1000 mg/kg CHI group. The levels of IgM and IgA tended to be increased (P < 0.1) by dietary CHI at later stage of the experiment; (2) the addition of 500 mg/kg CHI in diets increased (P < 0.1) total superoxide dismutase activity and decreased (P < 0.05) malondialdehyde content in serum at early and later stages, respectively. In conclusion, these results indicated that addition of 500 mg/kg CHI affected humoral and cellular immune responses, and improved the antioxidative function of beef cattle.

“…Feed additives such as probiotics and prebiotics can improve stress tolerance and immunity of aquatic animals including marron [6,[11][12][13][14][15][16]. Our previous studies indicated that Bacillus mycoides, a marron origin customised probiotic, possessed a number of favourable probiotic properties [17], significantly improved gastrointestinal (GIT) health of marron [18] and improved immunity against the pathogenic bacterium Vibrio mimicus [19], a dominant bacterial pathogen of freshwater crayfish in aquaculture [20][21][22].…”

The present study examined the effect of simulated transport on marron, Cherax cainii, (Austin, 2002) after a 10 week feeding trial using basal diet or customised probiotic, Bacillus mycoides supplemented diet by measuring intestinal bacterial population, total haemocyte count (THC), bacteraemia, morbidity, dehydration and mortality.Packing steps followed the established standard packing method for live transportation of marron. Each treatment group consisted of six polystyrene boxes (65 × 30 × 40 cm 3 ), and each box contained 30 marron from each feeding group. The sealed boxes were placed on a trolley at room temperature to give the effect of transportation. Boxes were opened at 24 th and 48 th hour post simulated transport and marron from each treatment group were returned to the culture tank. After temperature acclimation, the marron were observed for mortality and samples were collected to assess marron health and immunity.The results demonstrated that no mortality was observed at 24 h of transport both in basal diet and probiotic diet fed marron, however at 48h of transport the survival of probiotic fed marron was significantly higher (100 ± 0.0%) compared to survival (93.3 ± 2.8%) of basal diet fed marron. The higher survival rate of probiotic fed marron was also sustained by superior health and immune status indicated by higher intestinal bacterial population, higher total haemocyte count and lower haemolymph bacteria (bacteraemia) level. In brief, supplementation with host origin customized probiotic B. mycoides significantly improved marron tolerance to a live transport stress test, which resulted in no mortality up to 48h of transport.

“…The MOS contained in microcapsules also influenced the growth performance indirectly through an improvement in the functional integrity of the enterocyte membrane in relation to an enhanced assimilation or digestion of specific nutrients or to possible changes on the levels of peptides that regulate either the peripheral satiation system (satiation and appetite signals) and also modification of the morphology of the digestive tract of shrimp (Torrecillas et al, 2014;Dimitroglou et al, 2013). The TEM analysis in Zhang et al (2012) showed that MOS supplementation in diet could significantly increase the length of the intestinal microvilli of L. vannamei. Therefore, it could improve the absorption of nutrients and growth performance.…”

“…The composition of synbiotic microcapsules in this study referred to the previous dose (Wang, 2007), i.e 1% w/w Bacillus NP5 Rf (Zhang et al, 2012) with some modifications. Probiotic biomass was produced by performing subculture technique on SWC (Sea Water Complete) broth media (5 g bacto peptone, 1 g yeast extract, 3 mL glycerol, 750 mL sea water and 250 mL distilled water) with 10% v/v of Bacillus NP5 Rf J.…”

White Spot Syndrome Virus (WSSV) is one of the most devastating shrimp pathogen which causes up to 70-90% mortality in commercial shrimp farming. This study was aimed to evaluate the effectiveness of synbiotic microcapsule (Bacillus NP5 Rf R and mannan oligosaccharide combination) feed supplementation on the immune responses and growth performance of WSSV infected Pacific white shrimp. Shrimps (4.411±0.395 g) were cultured and fed by pellet containing synbiotic microcapsule at different dosages for 30 days, i.e., designated as 0.5% (M1), 1% (M2), 2% (M3) (w/w) and without synbiotic microcapsule addition (negative and positive controls). The synbiotic was encapsulated by spray drying method. Challenge test was performed at 31st of cultivation day by performing intramuscular injection of WSSV filtrate (10 4 copies mLG 1 ). Compared with control, the shrimp fed by M2 and M3 were found to have higher (p<0.05) value of Total Hemocyte Count (THC), pro Phenol Oxidase (proPO) and Respiratory Burst (RB) activity compared to positive control. The results showed that the Specific Growth Rate (SGR) of M1 and M2 were higher (p<0.05) than controls. Yet, the Feed Conversion Ratio (FCR) were lower (p<0.05) than controls. Above all, the survival rate of shrimps fed with microcapsule synbiotic were higher (p<0.05) than controls.
