  In the current scenario of increasing and emerging drug resistance in various microbial pathogens, traditional antibiotics are becoming less effective and thus globally research has focused on developing alternative therapeutic regimens having efficient germ killing abilities. The leading alternatives include use of phages, prebiotics, probiotics, cytokines, avian egg yolk antibodies, toll like receptors, medical herbs and various other immunomodulatory/immunotherapeutic approaches. Out of these valuable therapies, the application of oral passive immunization using avian egg yolk antibodies (Immunoglobulin Y, IgY) offers promising future avenues for designing and developing novel prophylactic and treatment strategies against infectious diseases in both humans and animals, particularly countering the enteric pathogens. Hitherto studies confirm beneficial applications of IgY antibodies in animals (Calves, lamb and goat, cats and dogs), poultry and humans, however such studies in fish and aquatic animals are comparatively less. The present study presents as overview on avian egg antibodies, their salient features, advantages and limitations and then describes the potential therapeutic applications of IgY for the prevention and treatment of infectious diseases of fish and aquatic animal species, as well as speculating the future prospects of upcoming IgY technology. Taking into account the valuable prophylactic and therapeutic applications of IgY antibodies, further explorative research in this area could pave way for designing and developing effective pharmaceuticals and treatment options for various infectious diseases of fish/aquaculture animals as well as for safeguarding health of humans and their companion animals.

  Objective: The present study was performed to determine the influence of dietary Acetic Acid (AA) supplementation on growth performance, intestinal histomorphology, blood hematology and serum constituents of broilers. Methodology: A total 200 chicks were randomly divided into five experimental groups with four replicates each (10 chicks/replicate) in a complete randomized design experiment. Treatments were as follow: (AA0: control, AA1: basal diet+0.1% acetic acid kg–1, AA2: basal diet+0.2% acetic acid kg–1 and AA3: basal diet+0.3% acetic acid kg–1). Results: The results showed that AA supplementation improved weight gain (p<0.001) and feed conversion ratio (p<0.001). Generally, acetic acid supplementation at 0.3% level improved bird’s performance during 2-6 weeks of age. Increased intestinal length and higher intestinal weight were recorded in AA treated birds. Significant reduction in pH of proventriculus and ventriculus (p<0.01) was observed with in dose related manner. No significant effects were observed on dressing percentage. Histological observations revealed that intestinal morphology professed positive effects under AA treatment. Furthermore, the effect of dietary AA supplementation was significant (p<0.05) only on lymphocytes count and heterophil/lymphocyte ratio. It is obvious that blood of birds fed AA3 diet had the highest concentration of calcium, phosphorous, total protein and globulin comparing with the control diet and other levels of AA. The best results of all parameters were observed in AA3. Conclusion: Based on the results, it could be concluded that AA supplementations in feed employs positive effect on performance and intestinal histomorphology of broilers.

  Objective: The current study was conducted to assess the biological in vitro impacts of cyadox (CYA) as growth promoter on erythrocytes isolated from rabbits. Methodology: Suspensions of erythrocytes were divided into 6 groups (5 replicates each), 1st group served as control; 2nd, 3rd, 4th, 5th and 6th groups were respectively subjected to CYA at 2.5, 5, 10, 20 and 40 μg mL–1, then incubated for 3 and 6 h at 37°C and shaken gently from 3-4 times per hour. Results: The data obtained revealed that the low doses of CYA (2.5 and 5 μg mL–1) diminished the reduced glutathione (GSH) content and enhanced the catalase (CAT) and superoxide dismutase (SOD) activities even after incubation with CYA for 6 h. These concentrations also had no linear or quadratic influences on the values of malonaldehyde (MDA) and protein carbonyl (PrC) as well as the hemoglobin (Hb), adenosine triphosphate (ATP) and total protein (TP) levels in erythrocytes. Increasing the concentration of CYA (10, 20 and 40 μg mL–1) and increasing the incubation period resulted in depletion of GSH, inhibited the CAT and SOD activities and decreased the protein content in the treated RBCs while the levels of PrC, MDA, Hb, TP and ATP were increased in response to increasing the dose and incubation time. Conclusion: From these results it could be concluded that CYA may be safe at recommended doses (2.5 and 5 μg mL–1) while using at high concentrations revealed pro-oxidant properties which could in turn affect cell survival.

  The concept of "Nanoparticle" is not applied to the individual molecules but it is usually used to indicate to the inorganic materials. These particles vary into different kinds due to their ability to carry different components and act to various conditions of the environment. The different sorts of nanoparticles are used in various sectors such as nutrition, pharmacy, medicine, drug delivery, therapeutics, vaccine formulations, diagnostics, chemical industry, biotechnology and biomedicine for safeguarding health of humans and animals as well as enhancing growth and production performances. The application of nanotechnology is very important in the 21st century to clean up the environment from contaminants by eco-friendly, sustainable, green and economically technologies. Nanotechnology became an essential element of pharmaceutical sciences and nanomaterials have found many applications in systems of drug delivery to enhance the therapeutic performance and efficacy of different drugs and medicines. Most of the current "Nano" systems of drug delivery are linage of conventional dosage forms like nanomicelles, nanoemulsions and nanosuspensions. Also, nanotechnology will have a major role in the future areas of animal nutrition research. Nano additives could be incorporated in capsules or micelles of protein or other natural feed or food component. The use of nutrient nanoparticles may improve the bioavailability of carried nutrients by the epithelial barriers of the gut and their susceptibility to gastrointestinal degradation by digestive enzymes. Offering the matter in a nano form may also improve the functionality of feed/food molecules to the benefit of final product quality.

  Chicory (Cichorium intybus) is a perennial herbal plant of the dandelion family Asteraceae, usually with bright blue flowers, rarely pink or white. Several varieties are cultivated for salad leaves, chicons or roots which are baked, ground and used as a coffee substitute and supplement. It is also grown as a forage plant for poultry and animal. In addition, chicory herb plays a key role as antioxidant, anti-inflammatory, sedative, immunological, productive and reproductive enhancer, cardiovascular, hypolipidemic, anticancer, anti-protozoal, gastroprotective, antidiabetic, analgesic, anthelmintic, antimicrobial, wound healing and bitter tonic without inducing therapeutic adverse effect. Regarding the hepatoprotective activity, chicory extract reduced the levels of hepatic enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP). Also, chicory plant is a good and very important protective source for hepatocytes and other liver cells as well as it is used as prebiotic against some species of pathogenic bacteria for both in vitro and in vivo. Moreover, it enhances immunity and feed efficiency by decreasing pathogenic microorganisms of gastrointestinal tract. Cichorium intybus roots also were used for the relief of mild digestive disorders, such as feeling of flatulence, abdominal fullness, temporary loss of appetite and slow digestion. The present study highlights the importance of chicory as a feed additive used to improve growth and productive performance of poultry as well as salient beneficial applications in animals and humans. Furthermore, it explains the mechanisms of action underlying the beneficial effects of chicory and to find the effective level in poultry that would act as liver tonic.
