“…Compared with other treatments, administering nanoencapsulated form of the extracts significantly (P < 0.05) enhanced IgY and IgM at 35 and 42 days of age. These findings support previous research into this area of the brain and links aloe vera extract and humoral immunity (Akhtar et al, 2012). The authors reported that oral administration of aloe vera extract resulted in higher numbers of anti-SRBC antibody (total Igs, IgM and IgG) titers.…”

Effects of nanoencapsulated aloe vera, dill and nettle root extract as feed antibiotic substitutes in broiler chickens

Abstract. Aloe vera, nettle and dill are herbs that have been used in the poultry diet as feed additives to utilise their benefits in improving performance, immune response and health of broiler chickens. However, reactive and volatile properties of bioactive compounds in herbal extracts cause limitations on direct usage of them in the diet. The use of chitosan (CS) nanoparticles for the entrapment of active components has gained interest in the last few years due to its mucous adhesiveness, non-toxicity, biocompatibility and biodegradability. This study was an effort to evaluate effects of nanoencapsulated extracts of aloe vera, dill and nettle root used in diet on performance, carcass traits and serum immunoglobulin (IgM and IgY) concentrations in broiler chickens. Chitosan nanoparticles were prepared by using ionotropic gelation principle. After nanogel preparation of herbal extracts, a total of 240 Ross (308) broiler chicks were divided into eight treatments, with three replicates of 10 birds. The eight dietary treatments consisted of control (no additives), antibiotic (bacitracin 500 g t −1 ), non-encapsulated and nanoencapsulated extracts of aloe vera, dill and nettle root. In each experimental period, non-encapsulated (free extracts) and nanoencapsulated extracts of aloe vera, dill and nettle roots were added in amounts of 0.02, 0.025 and 0.05 % to starter, grower and finisher diets, respectively. Birds in different treatments received the same diets during the experimental periods. Results revealed that increasing both non-encapsulated and nanoencapsulated herbal extracts to 0.05 % in finisher diets improved body weight gain in the time period of 28-42 days and consequently the whole time from 1 to 42 days. However, in these periods, birds fed a diet containing nanoencapsulated dill extract had a significantly (P < 0.05) higher body weight gain compared with the antibiotic group, while non-encapsulated dill extract treatment was intermediate. The addition of nanoencapsulated nettle extract in diet significantly (P < 0.05) improved feed conversion efficiency in the 28-42-day period compared with the antibiotic group. In comparison with the antibiotic group, nanoencapsulation of dill extract could profoundly improve growth performance and can therefore be used as a substitute for antibiotics in the diet of broiler chickens.

In the present study, polysaccharides have been isolated and evaluated as biological response modifiers in chickens. Aloe (A.) vera polysaccharides were administered in chickens for three consecutive days and used for immunological evaluation. Results showed significantly higher (p<0.05) lymphoproliferative response to PHA-P and Con-A in chickens of polysaccharides administered groups as compared to control. Carbon particle clearance assay showed significantly higher clearance index (K) in control group, indicating presence of more carbon particles in blood. Phagocytic index (α) showed significantly higher response in all three polysaccharides administered groups. Significantly higher humoral immune responses [total immunoglobulins (Igs), IgG and IgM titers] were also detected in treatment groups. Biomolecule administered chickens showed better feed conversion ratios and significantly higher (p<0.05) weekly weight gains. From the current study, it was concluded that A. vera derived polysaccharides have potential to be used as immunotherapeutic agent(s) in chickens.

“…Further, significantly higher weight gains and antibody titers (p<0.05) were observed in chickens administered with Aloe vera extracts as compared to those in the control group. It was concluded that Aloe vera may be a potential and variable candidate to stimulate the immune responses and can be used successfully as an immunotherapeutic agent against coccidiosis in industrial broiler chickens [83] .…”

Gastroenterology and Hepatology Researchdation, and the possible putative prophylaxes to optimize cognitive decline in older adults with pre-diabetes symptom. Because of the diversities of placental extract and Aloe vera as biogenic stimulants, present review introduced the briefly selected authors' intentions in each topical subject. Specially, the influence of gut microbiota to host is astonishing and highlighting that the consequence of our behaviours affect not only the environment without, but also that within us. Based on geriatric and neurological viewpoint, present review highlights current therapeutic strategies of placenta extract and Aloe vera as the so-called "biogenic stimulants", aimed at producing a biological rejuvenator in placental extract and improving cognitive function via modifying the brain's insulin sensitivity in Aloe vera.
