Newcastle disease virus (NDV) can cause severe disease in chickens. Although NDV vaccines exist, there are frequent reports of outbreaks in vaccinated chickens. During 2009-2010, despite intense vaccination, NDV caused major outbreaks among commercial poultry farms in Indonesia. These outbreaks raised concern regarding the protective immunity of current vaccines against circulating virulent str...

Sugar cane extract (SCE), the residue after removing glucose, fructose, and sucrose from sugar cane juice, has growth-promoting, antistress, and immunostimulation effects. The objective of this study was to investigate the effects of refeeding dietary SCE on recovery of BW and intestinal histology after withdrawing feed from chickens. Forty-eight male Sanuki Cochin chickens were assigned random...

A total of 448 Ross 308 male broiler chickens were assigned to seven treatments with four replicates, each containing 16 chicks. The birds were reared from d 21 to 42 and effects of physical sizes (ad libitum by a basal commercial broiler diet with 3050 Kcal/Kg ME and 19.06% CP/Kg from 21 to 42 d. The chickens which received clinoptilolite (1.5% with particle size of 0.4-0.8 mm) showed a signif...

The study was conducted to evaluate the effect of different levels of synthetic lysine (sLys) on dry matter intake (DMI), average daily weight gain (ADG), dry matter conversion ratio (DMCR), carcass characteristics and economics of productionof finisher broiler chicks. As 240 day-old broiler chicks were randomly distributed to 12 pens of 20 chicks each and assigned to four treatment rations in ...

Newcastle disease (ND) is a major threat to poultry industry production throughout developing countries. The Newcastle disease viruses (NDVs) infecting industrialized and indigenous poultry in Iran are velogenic strains and responsible for the frequent outbreaks of ND in poultry farms even in vaccinated flocks causing serious economic losses in the commercial and indigenous poultry. However, va...

The pathogenesis of five different Newcastle disease virus (NDV) isolates representing all pathotypes was examined in commercial and specific pathogen-free (SPF) turkeys. Experimentally-infected birds were monitored clinically and euthanatized, with subsequent tissue collection, for examination by histopathology, by immunohistochemistry for the presence of NDV nucleoprotein, and by in situ hybr...

this study was conducted to evaluate the effects of different dietary levels of full fat safflower seed (0, 5, 10, 15 and 20% of diet) on performance, carcass characteristics and selected blood metabolites of broiler chickens from arbor acres plus strain. the experiment was designed with 350 commercial one-day-old male broiler chickens using completely randomized design with 5 dietary treatment...

Global competition for high standard feed-food resources between man and livestock, such as industrial broilers, is a concerning problem. In addition, the low productivity of scavenger chickens in developing countries leaves much to be desired. Changing the ingredients, and therefore, the nutrient composition of feed intake by commercial fed as well as scavenger chickens seems like an obvious s...

Objective: Indiscriminate use of antibiotics in poultry farms increases the chance antibiotic-resistant and ESBL producing bacteria Bangladesh. Therefore, study was undertaken to detect extended-spectrum β-lactamase (ESBL) Escherichia coli (E. coli) chickens. 
 Materials methods: A total 60 cloacal swab samples (20 from commercial layer, 20 broiler, Sonali chickens) were collected Rajshahi...

Background and Aims: Enteric diseases have had detrimental impacts on commercial poultry through depressing growth rates and caused considerable economic losses to poultry producers. Chicken astrovirus (CAstV) is one of the most common viruses related to enteric diseases in chickens, especially in young chicks. Materials and Methods: Chicken astroviruses were detected by reverse transcriptase ...
