“…The albumin concentration did not differ significantly (P>0.05) amongst the various regimens. This finding was consistent with [15], who did not find significant differences in the concentration of albumin in the blood serum when adding Cordyceps fungus rich in polysaccharides at a level of 1 g / kg feed. As for glucose, the results showed a significant increase (P≤0.05) in treatments T2, T4, T5 and T7 compared to treatments T1 and T3 and did not differ from treatment T6.…”

From October 28, 2021, to December 8, 2021, this study was done at the University of Anbar’s Department of Animal Production inside the College of Agriculture (42 days). The purpose of this study was to examine the effects of feeding broilers (aged 1–42 days) diets containing either a single dose or two doses of Cordyceps Sinensis (C.S) extract mushroom and the probiotic, as well as combinations of these ingredients, on the animals’ physiological performance and certain blood traits. In this study, 210 one-day-old (Ross 308) chicks weighing an average of 40g were split into seven treatments with three replicates each (10 chicks for each replicate). The control treatment (T1) was used as a baseline against which the effects of the experimental treatments could be measured. In treatments 2 and 3, C.S extract was added at 300 and 600 mg/kg feed, respectively. A probiotic was added to the meal at a dosage of 3 g/kg in Treatment 4 (T4) and 6 g/kg in Treatment 5 (T5). The sixth treatment (T6) added a probiotic (3 g/kg of feed) and a C.S. extract (300 mg/kg of feed). The seventh treatment (T7) involved adding 600 milligrams of C.S. extract per kilogram of feed in addition to 6 grams of probiotics per kilogram of feed. Treatments T1, T3, and T6 were shown to be statistically superior to T2 and T7 in terms of white blood cell trait (WBC), whereas Treatments T4 and T5 showed no significant differences. Treatments T3 and T7 were found to have a significantly (P≤0.05) higher heterozygous cell to lymphocyte ratio than treatments T2, T4, T5, and T6, but did not differ from the control treatment T1. Based on biochemical characteristics of the blood serum, it was found that the concentration of glucose in the blood was significantly higher in treatments T2, T4, T5, and T7 compared to treatments T1, T3, and did not differ between treatments T6 and T7 (P≤0.05). Treatments T2, T5, and T7 had a higher total protein concentration than treatments T1, T4, and T6, and did not differ significantly from treatment T3. Treatment T3 had the lowest total protein concentration. Treatments T2, T4, T5, and T7 had higher globulin concentrations than did treatments T1, T3, and T6 (P≤0.05). When comparing the effects of treatments T1, T4, T5, T6, and T7 on aspartate aminotransferase (AST), T1 and T4 showed a statistically significant (P≤0.05) reduction compared to treatments T2, T3, T5, T6, and T7. Concerning the concentration of alkaline phosphatase (ALP), the results showed a significant deterioration (P≤0.05) in treatments T3, T5 and T7 compared to treatments T1, T2, T4 and T6. Results reveal that treatment T3 significantly raises (P0.05) triglycerides and very low-density lipoproteins (VLDL) compared to treatment T2, but does not significantly differ from treatments T1, T4, T5, or T6 or T7. The results revealed that treatments T3, T4, and T5 considerably improved cholesterol concentration compared to treatments T2, T6, and T7 (P≤0.05), while treatment T1 did not significantly affect cholesterol concentration (control treatment). HDL (high-density lipoprotein) levels were found to be substantially (P≤0.05) higher in T1 (control treatment) and T3 compared to T4, T5, and T6, but did not differ significantly from T2 and T7. The results showed that the concentration of low-density lipoproteins (LDL) was substantially higher (P≤0.05) in treatments T2, T4, and T5 compared to treatments T1, T3, and T7, but did not differ significantly from treatment T6.

“…In ovo technology, through which a tiny quantity of material is injected into the bird’s egg/embryo during incubation, offers a novel alternative for delivering bioactive compounds to the chick embryo before hatching. Recent experiments from various researchers showed the benefits of in ovo feeding technology on body weight, feed conversion ratio, and pectoral meat yield [ 31 , 32 , 33 , 34 ].…”

The chicken gut is the habitat to trillions of microorganisms that affect physiological functions and immune status through metabolic activities and host interaction. Gut microbiota research previously focused on inflammation; however, it is now clear that these microbial communities play an essential role in maintaining normal homeostatic conditions by regulating the immune system. In addition, the microbiota helps reduce and prevent pathogen colonization of the gut via the mechanism of competitive exclusion and the synthesis of bactericidal molecules. Under commercial conditions, newly hatched chicks have access to feed after 36–72 h of hatching due to the hatch window and routine hatchery practices. This delay adversely affects the potential inoculation of the healthy microbiota and impairs the development and maturation of muscle, the immune system, and the gastrointestinal tract (GIT). Modulating the gut microbiota has been proposed as a potential strategy for improving host health and productivity and avoiding undesirable effects on gut health and the immune system. Using early-life programming via in ovo stimulation with probiotics and prebiotics, it may be possible to avoid selected metabolic disorders, poor immunity, and pathogen resistance, which the broiler industry now faces due to commercial hatching and selection pressures imposed by an increasingly demanding market.

“…Interestingly, recent studies revealed that APS could regulate lipid metabolism and adipogenesis ( 128 ). A previous study reported that in ovo injection of 4.5 mg APS enhanced carcass percentage, reduced abdominal fat, as well as reduced educed triglycerides, total cholesterol, low-density lipoproteins, and very low-density lipoproteins in the plasma of broilers ( 129 ). When compared with control group, APS treatment improved meat quality and feed conversion rate by reducing fat metabolism.…”

Intestine is responsible for nutrients absorption and plays a key role in defending against various dietary allergens, antigens, toxins, and pathogens. Accumulating evidence reported a critical role of intestine in maintaining animal and human health. Since the use of antibiotics as growth promoters in animal feed has been restricted in many countries, alternatives to antibiotics have been globally investigated, and polysaccharides are considered as environmentally friendly and promising alternatives to improve intestinal health, which has become a research hotspot due to its antibiotic substitution effect. Astragalus polysaccharide (APS), a biological macromolecule, is extracted from astragalus and has been reported to exhibit complex biological activities involved in intestinal barrier integrity maintenance, intestinal microbiota regulation, short-chain fatty acids (SCFAs) production, and immune response regulation, which are critical for intestine health. The biological activity of APS is related to its chemical structure. In this review, we outlined the source and structure of APS, highlighted recent findings on the regulation of APS on physical barrier, biochemical barrier, immunological barrier, and immune response as well as the latest progress of APS as an antibiotic substitute in animal production. We hope this review could provide scientific basis and new insights for the application of APS in nutrition, clinical medicine and health by understanding particular effects of APS on intestine health, anti-inflammation, and animal production.
