This study investigated the effects of xylo-oligosaccharide (XOS) and flavomycin (FLA) on the performance and immune function of broiler chickens. A total of 150 ArborAcres broilers were randomly divided into three groups and fed for six weeks from one day of age in cascade cages. The diets of each test group were (1) a basal diet, (2) the basal diet supplemented with 2 mg/kg FLA, and (3) the b...

The objective of this study was to determine the energy values of soybean oil (SBO) and tallow (T) combined in different ratios, and to evaluate their effects on the performance, body composition, and serum lipid levels of starter broilers. In experiment I, a digestibility trial was performed to determine the energy value of the SOB and T mixtures using 100 12 to 21 -day-old broilers. In experi...

High environmental temperatures have deleterious effects, reducing the feed intake, live weight gain and feed efficiency of poultry. A study utilizing Ross 308 was conducted to evaluate the effects of vitamin C (Ascorbic acid) and glucose on broilers production reared under heat stress (32 ± 2 °C). One day-old, five hundred twenty five broilers were randomly assigned to 7 treatment groups with ...

The present study aimed at evaluating the effect of the probiotic thepax and yogurt (as probiotic) on the growth response and intestinal microflora results of broiler chickens. Two hundred forty day-old Ross 308 broilers were equally distributed into 12 floor pens and reared for 42 day. The treatments consisted of yogurt (10, 5 and 2.5% during starter, grower and finisher periods in the drinkin...

BACKGROUND Enterococcus cecorum is considered as an emerging pathogen in poultry and can cause substantial losses in broiler flocks. Femoral head necrosis and spondylitis were described as the main pathological changes in infected chickens. Nevertheless, little is known about the pathogenesis of Enterococcus cecorum infection in broilers. This report shows for the first time the whole course of...

The study was conducted on 72 day old straight run commercial broiler chicks (DOC) till 6 weeks of age to investigate the effect of Tulsi (Ocimum sanctum) leaf powder (TLP) on the hematological parameters of broilers. Chicks were randomly divided into four groups of 18 chicks each. Control group received standard broilers diet. Chicks in second, third and fourth group received standard broilers...

Fasting heat production (FHP) is used for characterizing the basal metabolic rate of animals and the corresponding maintenance energy requirements and in the calculation of net energy value of feeds. In broilers, the most recent FHP estimates were obtained in the 1980s in slow-growing and fatter birds than nowadays. The FHP values (n=73; six experiments) measured in 3 to 6-week-old modern lines...

Malabsorption syndrome (MAS) is a multifactorial syndrome which is characterized by enteric disorders and reduced growth rates of broilers. Such condition is responsible for significant economic losses to the poultry industry. A possible association between chicken parvovirus (ChPV) infections and the occurrence of MAS has been proposed. However, such association has not to date been elucidated...

A study was conducted to determine the growth performance of Cobb broilers supplemented with varying concentrations of Moringa oleifera Aqueous Leaf Extract (MoALE) via the drinking water. A total of four hundred day-old chicks were randomly distributed into four treatment groups, replicated four times with twenty-five broilers per replicate. The growth performance of broilers was evaluated bas...

During the last 5 to 6 decades antibiotics have been used in an increasing amount in the field of poultry production. Antibiotics are used for treatments and as growth promoters. Now-a-days there is an increasing demand to produce antibiotic free poultry and livestock. For this purpose in my experiment the chickens were fed Probiotics at the first day before providing them any feed. In the case...
