Broiler chickens are susceptible to diseases come from bacteria. The bacteria that usually infect broiler is Escherichia coli which can cause diarrhea. precaution done using antibiotics, usually. This study aimed analyse the effect of Batak Onion (Allium chinense) extract and powder as an antibiotic performance chicken. Research method was completely randomized design (CRD) with 7 treatments 3 ...

The effects of enriching broiler chicken diets with a vegetable source of n-3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the accumulation of n-3 long chain polyunsaturated fatty acids (LCPUFA) in chicken meat were investigated. Sixty unsexed one-day-old broiler chickens (Cobb 500) were randomly allocated to one of six diets (n=10 birds/diet) for 4 weeks. The ALA levels varied fro...

Contrary to a commonly held belief that broiler chickens need more space, there is increasing evidence that these birds are attracted to other birds. Indeed, commercially farmed birds exhibit a range of socially facilitated behaviours, such as increased feeding and preening in response to the presence of other birds. Social facilitation can generate feedback loops, whereby the adoption of a par...

Broiler chickens aged 40 and 46-days-old from two neighboring flocks belonging to a commercial broiler complex, presenting facial edema, severe respiratory signs and 10% mortality were analyzed. Pneumonic lesions and opaque thoracic and abdominal air sacs with foamy exudate were seen at postmortem examination. Histopathology of lungs showed fibrinoheterophilic pneumonia in both cases. Small pin...

The effect of different doses of alpha-galactoside (RFOs) preparations from Pisum sativum L. cv. Opal, injected into eggs during embryogenesis, on maintaining a high number of bifidobacteria, selected chicken broiler traits and the lipoprotein level of blood were studied. Two independent experiments were conducted. In the first, Ringer water solution containing 1.763 mg/egg of fructooligosaccha...

Two experiments were conducted to investigate the potential for Forsythia suspensa extract (FSE) to substitute for antibiotic in broiler chicken. First, a well-diffusion assay procedure and a 2-fold dilution method were used to determine the bacteriostatic activity of FSE on Escherichia coli K88, staphylococcus aureus, and salmonella was assayed. An inhibitory effect of FSE was observed on the ...

Objective- The pineal gland and its principal hormone melatonin play an important role in the circadian organization in birds. However, little is known about the role of melatonin in cardiac activity of broiler chicken. The aim of this study was to assess the impact of intracerebroventricular injection of melatonin in electrocardiographic parameters, heart rate and mean electri...

US Department of Agriculture Food Safety and Inspection Service (FSIS) data on Salmonella enterica serotype Enteritidis in broiler chicken carcass rinses collected from 2000 through 2005 showed the annual number of isolates increased >4-fold and the proportion of establishments with Salmonella Enteritidis-positive rinses increased nearly 3-fold (test for trend, p<0.0001). The number of states w...

An experiment was carried out to study the hematological and biochemical changes of stunting syndrome in broiler chicken from day old ( group I) and 3 weeks (group III) of age to 8 weeks of age in two phases along with group II and group IV as control. Birds were slaughtered at 3, 5 ,7 and 8 weeks of age and the blood samples were collected and analyzed. The mean PCV, Hb, TEC values were reduce...

avian leukosis viruses (alvs) cause different types of tumours in poultry and can affect the health and egg production of the birds. to investigate the presence of the virus in chicken layer flocks in shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...
