“…Humoral and cell mediated immune response showed significant (P<0.05) improvement in MOS supplemented treatments (Table 4). The results are in accordance with Sohail et al (2013) and Huang et al (2007). Stress reduces the weight of lymphoid organs so it could be postulated that MOS supplementation reduces the heat stress in broilers leading to higher lymphoid organ weight (Houshmand et al 2012).…”

An experiment was conducted on broiler chicks (n=120), reared in cages on a standard diet up to 14 th day of age and thereafter up to 42 nd day (14-42d) on test diets with or without MOS. The 14 th day old chicks were randomly distributed into three dietary treatment groups viz., T 1 (control diet), T 2 (control diet with MOS @ 0.3%) and T 3 (control diet with MOS @ 0.5%). Each dietary treatment comprised of four replicates of eight birds each. Experiment was carried out during hot-dry summer. It was found that production indices improved (P<0.001) significantly during all phases. Cellular and humoral immunity at 28 th day of age improved significantly (P<0.05) due to MOS supplementation. The percentage of hemoglobin, protein, AST and ALT increased significantly (P<0.001) in MOS supplemented group at 28 th as well as 42 nd day of age. While H:L ratio, serum corticosterone and cholesterol levels decreased significantly (P<0.001) in MOS supplemented groups. Supplementation of MOS at the both levels caused significant (P<0.001) down regulation of HSP70 expression in jejunum tissues during 28 th and 42 nd day. Based on this study it was concluded that supplementation of 0.3% MOS in broiler diets significantly improved their performance and welfare during heat stressed conditions.

The effect of chitosan incorporated into feed formulation on the growth, feed utilization, body composition and histological response of sea bass (Dicentrarchus labrax) was investigated. Final fish weight, feed conversion ratio (FCR), specific growth rate (SGR), protein efficiency ratio (PER), protein productive value (PPV), and energy utilization (EU) of sea bass feed chitosan supplemented diet and the control diet were determined at the end of experiment. Data presents mean ± SD from triplicate determination (n = 3) for 75 days feeding trial. Different concentrations (0.5, 1.0, 2.0, 3.0 & 4.0) and control without chitosan incorporated with total fish feed in the form of dry diets were fed for 75 days. Average final weight (FW) was significantly higher at diet 3 (1 g•kg −1 chitosan) and the lowest in control fish group, specific growth rate (SGR) was significant at diet 3. Also, protein efficiency ratio (PER), protein productive value (PPV), and energy utilization (EU) showed the same trend. The chemical body composition, crude protein, dry matter, crude fat and ash were significant (P ≤ 0.01) different compared to control groups. The present investigation suggested that the chitosan incorporated into diets of sea bass fish certainly enhanced the non specific responses and reduced mortality and also improved the growth performance of fish.

“…According to Bueter et al (2013), the chitosan particles are recognized via specific receptor(s) and phagocytosed, inducing a response, which is not all defined, and up-regulating the innate immune system in mammals. It has been suggested that dietary oligochitosan can act as a prebiotic in chickens (Huang et al, 2005(Huang et al, , 2007. Huang et al (2007) suggested that the prebiotic effect of chitosan could be related to a chitosan attachment to the bacteria, leading to an immune response to this antigen, or by direct stimulation of the immune system.…”

Public concern with the incidence of antibiotic-resistant bacteria, particularly among foodborne pathogens such as Salmonella, has been challenging the poultry industry to find alternative means of control. The purposes of the present study were to evaluate in vitro and in vivo effects of chitosan on Salmonella enterica serovar Typhimurium (ST) infection in broiler chicks. For in vitro crop assay experiments, tubes containing feed, water, and ST were treated with either saline as a control or 0.2% chitosan. The entire assay was repeated in three trials. In two independent in vivo trials, 40 broiler chicks were assigned to an untreated control diet or dietary treatment with 0.2% chitosan for 7 days (20 broiler chicks/treatment). At day 4, chicks were challenged with 2 · 10 5 colonyforming units (CFU) ST/bird. In a third in vivo trial, 100 broiler chicks were assigned to untreated control diet or dietary treatment with 0.2% chitosan for 10 days (50 broiler chicks/treatment) to evaluate ST horizontal transmission. At day 3, 10 birds were challenged with 10 5 CFU ST/bird, and the remaining nonchallenged birds (n = 40) were kept in the same floor pen. In all three in vitro trials, 0.2% chitosan significantly reduced total CFU of ST at 0.5 and 6 h postinoculation compared with control ( p < 0.05). In two in vivo trials, at 7 days, dietary 0.2% chitosan significantly reduced total CFU of recovered ST in the ceca in both experiments. Dietary 0.2% chitosan significantly reduced total ST CFU recovered in the ceca of horizontally challenged birds in the third in vivo trial. Chitosan at 0.2% significantly reduced the CFU of recovered ST in vitro and in vivo, proving to be an alternative tool to reduce crop, ceca, and consequently carcass ST contamination as well as decreasing the amount of ST shed to the environment.
