1. Effect of Dietary Inclusion of Sodium Bicarbonate on Digestibility of Nutrients and Immune Response in Caged Layers During the Summer
ABSTRACT The aim of this project was to investigate the effect of dietary inclusion of sodium bicarbonate (NaHCO3) on nutrient digestibility and immune response of caged layers during summer when the temperature exceeds 40 ˚C. For immune response trial, White Leghorn layers (n=160; 24 weeks old) were purchased from a poultry farm and were divided into five

2. Effects of raw propolis or water and ethanol extracts of propolis on performance, immune system, and some blood parameters of broiler breeders
ABSTRACT The objective of this study was to determine the effects of raw bee propolis and water or ethanol extract of propolis on growth performance, some blood parameters, and immunoglobulins in 15-20-week-old Ross-308 broiler breeders. The birds in the control were fed a diet without propolis, whereas the birds in the treatment groups were fed diets with r

3. Efficacy of Zinc/Creatine Supplementation on Improving Growth Performance of Local Balady Chicks
ABSTRACT An experiment was designed to study the efficacy of Zinc and or creatine monohydrate (CMH) supplementation, either alone or in combination, on improving growth performance of Balady chicks. A total number of 144 Balady chicks were randomly divided into four equal groups. The first treatment was fed the basal diet and served as control, while groups

4. Phylogenetic and Pathotypic Characterization of a Newcastle Disease Virus Strain Isolated from Ducks and Pigeons in Hubei, China
ABSTRACT Newcastle disease is a highly contagious disease responsible for major outbreaks and considerable economic losses in the poultry industry in China. There is still little information available regarding gene characterization of the NDV, especially in ducks and pigeons. Therefore, the aim of this study was to investigate NDV isolated from ducks and pi

5. Phylogenetic and pathotypic characterization of newcastle disease virus in Tibetan chickens, China
ABSTRACT: Chickens are considered to be potential reservoirs of Newcastle disease virus (NDV). In this study, six Newcastle disease virus strains were isolated and characterized in Tibetan chickens. The HN gene was sequenced, and phylogenetic relationship to reference strains was studied. The phylogenetic analysis demonstrated that these six isolated strains

6. Immune Regulatory Effects of Enteromorphaclathrata Polysaccharides on Nd Attenuated Vaccine in a Chicken Model Infected with Reticuloendotheliosis Virus
ABSTRACT Reticuloendotheliosis virus (REV) infection has frequently affected the poultry industry in recent years. The infection with REV weakens the immune responses of the infected poultry. It is reported that Enteromorphaclathrata polysaccharides are capable of regulating immune function. In order to investigate the immuno regulatory effects of Enteromorp

7. Effects of arginine and phytogenic additive supplementation on performance and health of brown-egg layers
ABSTRACT This study was performed to evaluate the effects of the association of different digestible arginine and phytogenic additive dietary levels on performance and health status of brown-egg layers. In this study, a total of 504 33-week-old Hisex Brown layers were distributed into a completely randomized experimental design to a 4 × 3 factorial arrangem

9. Carcass Traits and Immune Response of Broiler Chickens Fed Dietary L-Carnitine, Coenzyme Q10 and Ractopamine
ABSTRACT This study was conducted to evaluate the effects of coenzyme Q10, L-carnitine and ractopamine supplementation, alone and in combinations, on carcass traits and immune response of broiler chickens. Five hundred and twelve one-day-old Ross 308 male broiler chickens were randomly allocated into eight treatments with four replicates each. A 2×2×2 fact

10. COMPARATIVE EVALUATION OF THE PROTECTIVE EFFICACY OF DIFFERENT VACCINATION PROGRAMS AGAINST A VIRULENT FIELD STRAIN OF THE NEWCASTLE DISEASE VIRUS IN BROILERS
ABSTRACT Despite the intensive vaccination programs used for controlling Newcastle disease (ND) in the Iranian poultry industry, outbreaks of ND have been reported in poultry farms. This study was conducted to evaluate the effectiveness of vaccines for the protection against ND infection and virus-shedding period of velogenic Newcastle disease virus (vNDV) f

11. SURVEILLANCE FOR NEWCASTLE DISEASE VIRUS, AVIAN INFLUENZA VIRUS AND MYCOPLASMA GALLISEPTICUM IN WILD BIRDS NEAR COMMERCIAL POULTRY FARMS SURROUNDED BY ATLANTIC RAINFOREST REMNANTS, SOUTHEASTERN BRAZIL
ABSTRACT The geographic overlap between areas of Atlantic rainforest and human activities allows interactions to occur between humans and wild and domestic animals. Despite the great importance of the domestic animal-wildlife-human interface that occurs at poultry farms in terms of public health, economic production and wildlife conservation, there are few s

12. Effects of Glycyrrhizic Acid on Productive and Immune Parameters of Broilers
ABSTRACT Considering that glycyrrhizic acid (GRA) has been shown to have in-vitro and in-vivo antiviral activity against a wide range of viruses as well as immunostimulating activity, a trial to evaluate its effects on the performance and the immune response against Newcastle disease of broiler chickens was carried out. The study was performed with one-day-o
