BACKGROUND The present study was conducted to investigate the effects of oridonin (ORI) on growth performance, relative organ weight, lymphocyte proliferation, phagocytic function of neutrophils, and cytokine concentration in broiler chickens. A total of 240 one-day-old Arbor Acres male broilers were randomly assigned to four treatments with six replicate pens of 10 broiler chickens per pen. Br...

The aim of the experiment was to evaluate effects of zinc gluconate (ZnGlu) and probiotic administration on the daily rhythm of cloacal temperature (tcloacal) in broiler chickens of different age groups during the hot-dry season. One-day-old broiler chicks (n = 60) were divided into groups I-IV of 15 chicks per group, and treated for 35 days: Group I (control) was given deionized water; Group I...

The effect of dietary supplementation of selenium in an organic form on performance, carcass traits and selenium content in tissues of broiler cockerels Ross 308 was studied. The soya-wheat-maize diet contained 50 mg vitamin E/kg. The experiment was conducted on 810 straight-run broiler cockerels randomly divided into 3 groups: group I – control, without selenium supplement; experimental group:...

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...

this study was conducted to assay the use of saturejahortensis l. (savory) essential oil in the drinking water on broiler production and blood glucose, uric acid, creatinin and cholesterol. four hundred and twenty day old broiler chickens (ross 308) was used in a completely randomized design with 6 treatments and 5 replicate. experimental treatments included: 1) control, 2) tween (a solvent for...

DERAKHSHANFAR, A., R. GHANBARPOUR: A study on avian cellulitis in broiler chickens. Vet. arhiv 72, 277-284, 2002. ABSTRACT Avian cellulitis in broiler chickens, especially on the thighs and abdominal wall, has been observed more frequently in recent years. In the present study, over a one-year period 98 broiler carcasses with cellulitis were diagnosed at slaughterhouse. The lesions were charact...

An experiment was conducted to increase the quality of rice bran by fermentation using Bacillus amyloliquefaciens and humic substances and its utilization as a feed ingredient for broiler chickens. The experiment was carried out in two steps. First, the fermentation process was done using a completely randomized design in factorial with 16 treatments: i) Dosage of B. amyloliquefaciens (2.10(8) ...

This study was conducted to evaluate the effects of Bacillus subtilis, Clostridium butyricum and Lactobacillus acidophilus (tri-strain probiotics, TSP) endospores in broilers. TSP can benefit the host animal by increasing nutrient absorption from the gastrointestinal tract and altering the intestinal ecosystem in poultry. A total of 500 day-old ROSS 308 mixed sex broiler chickens with an averag...

OBJECTIVE The objective of this experiment was to characterize the mRNA expression profile of type IIb sodium-inorganic phosphate cotransporter (NaPi-IIb) and the biochemical values of serum alkaline phosphatase (AKP), calcium, inorganic phosphorus, tibial ash and minerals of broiler chickens with aging. METHODS A total of 56 one-day-old Arbor Acres male broiler chickens were used. Broiler ch...

To asses the effect of turmeric (Curcuma longa) supplementation on antioxidants and immunity of broiler chickens, seventy five run day old coloured synthetic broiler chicks were randomly divided into 3 groups (25 chicks per each) of mixed sex. Group I served as control (without any supplementation), whereas birds in groups II and III were supplemented with 0.5% and 1.0% Curcuma longa powder res...
