  Trace elements supplementation is now widely considered not only essential but also beneficial to avian species. In the last few decades, chromium (Cr) has been considered to play important role in livestock and poultry nutrition, production and health and also as a potent toxin depending on the dosage levels. It has been documented that chromium may enhance growth rate and egg quality in meat and egg type chickens, respectively. Chromium is identified as an essential nutritional supplement and it has been utilized for weight gain, to improve Feed Conversion Ratio (FCR), increase relative organ weight, muscle development and relative breast mass, that’s why Cr has been a popular mineral supplement. It is also a potent antioxidant and hypocholesterimic agent. It increases the retention of other essential elements in blood and decreases their excretion. The beneficial effects of Cr have been linked with improved nutrient digestion and enhanced metabolism. Chromium (Cr) supplementation may improve function of various digestive organs such as liver and pancreas with regards to secretion of digestive enzymes. Supplementation of Cr has promising effects on the immune system by way of relative increase in lymphoid organ weight (bursa of Fabricius, spleen and thymus), decreased heterophil:lymphocyte ratio, enhanced antibody response against infectious diseases and increased Cell-Mediated Immune (CMI) response. In the current review some of the beneficial aspects of Cr in poultry nutrition and their possible mechanisms of actions are discussed with a view to explore and promote its optimum utilization in poultry production and health.

  Herbal medicine or herbalism is a time-honored practice of natural medicine that is older than mankind itself. The practice of using traditional herbal medicine based therapy is nowadays gaining more attention worldwide in both human and animal health care systems. Among the livestock sectors, poultry production systems are the most intensively reared with developments especially in the areas of nutrition, disease control, genetic improvement, management and organization of dietary requirements along with the pressure of increasing demand for poultry products as well as threats of emerging pathogens. So this sector is badly in need of sustainable therapeutic and production aids especially based on herbs because of the advantages like, low cost, easy availability, no residual effect, free from the threat of antibiotic resistance etc. Many herbs have been recorded to be fruitfully used by veterinarians to treat a variety of disease conditions in animals. The present study discusses the various useful and practical applications of the rich heritage of herbal wealth for safeguarding poultry health in general, combating infectious as well as non-infectious diseases caused by microbes and parasites )both ecto-and endo parasites( along with immunomodulatory actions for countering immunosuppressive diseases. Moreover, highlighting herb-based poultry growth promoters for increasing production performances use of herbs as antioxidants and their role in organic egg and meat production is a special attraction of the review that will draw the attention of the poultry specialists as well as farming community. The information will be useful to increase poultry production and protect the health of birds in a better way from traditional ways towards modern perspectives and also would promote and popularize usage of herbs amongst poultry producers.

  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.

  Background and Objective: Pistacia lentiscus L. (Anacardiaceae mastic tree or lentisk) is a bush playing an important role in the Mediterranean maquis ecosystem. For this purpose, a study on different accessions of mastic tree was carried out in Southern Italy to define the variability of characters related to morphology and survival under salt stress conditions. Methodology: This was study evaluated under nursery conditions the growing responses of 10 accessions of P. lentiscus to 6 different levels of salinization obtained by adding 0, 200, 400, 600, 800 and 1000 g of salts 100 L-1 of substrate, respectively. The following parameters were recorded; plant height, survival of plants and total root length, total biomass, number of leaves per plant and leaf area. Results: The results showed that P. lentiscus can well tolerate salt at high concentrations when grown under nursery conditions. Furthermore, among the investigated germplasm, a different plant accessions response to salt stress was observed. Conclusion: Thus, by identifying of mastic tree accessions more tolerant to salty soil and the revegetation of degraded agricultural lands can be attained.
