Malabsorption syndrome (MAS) is a multifactorial disease that causes intestinal disorders in broilers due to infection of the gastrointestinal tract with different infectious agents. The exact aetiology is unknown, although several viruses are isolated from MAS affected chickens. None of these isolated infectious agents alone inducted the malabsorption syndrome. MAS in broilers is characterised...

This experimental study aimed to elucidate the effect of dietary supplementation lauric acid and L-glutamic on production performance carcass characteristics broilers. Day-old broiler chicks (160) were randomly divided into four groups. The fed with diets, such as control diet without antibiotics (T1), + 0.1% (T2), 0.5% glutamate (T3), (T4). experiment was performed for five weeks using standar...

Three experiments were conducted to determine the effect of taurine on the intestinal development, bile acid concentrations, and hormonal status of chickens. In experiment 1, a total of 250 one-day-old broilers were randomly allocated to 5 treatments and supplemented with 0, 0.25, 0.50, 1.00, and 2.00 g/kg of taurine, respectively. Growth performance, weight and length of the small intestine, a...

Background: Nutritional strategies targeting improvement of poultry performance and disease prevention are currently being developed and in this respect the dietary intake of spiced essential oils and pre-biotics in raising broilers is receiving attention. OBJECTIVES: This study was conducted to compare the effects of diet containing ginger essential oils (GEO) and mannan-oligosaccharide (MOS) ...

control of poultry feed microbial contamination could reduce carcass contamination at processing plants and resultin improvement of public health. in this study the effects of commercial blend of organic acids (salkil® and formycine®), formalin 37% and formaldehyde gas on morphology of intestinal mucosa and gut microflora in broilers were investigated. three hundreds 1-d-old chicks (ross 308) w...

The study was conducted to investigate the effects of different levels of xylanase on performance, blood parameters, intestinal morphology, microflora and digestive enzyme activities of broilers. The wheat-based diets were supplemented with 0, 500, 1,000, 5,000 U/kg xylanase. Xylanase supplementation significantly (p<0.05) improved the feed:gain ratio of broilers from 1 to 21 d and 1 to 42 d. S...

a bstract background: the improved physical action following administration of supplements to bodybuilders was supported by changes in laboratory parameters. despite the fact that these supplements are sometimes associated both advantage and side effects, this study were conducted for the purpose of evaluating the possible effects of some commonly used supplements in bodybuilders on the hematol...

Background: Organic acids and ammonium salts added to drinking water can optimize productivity of broiler chickens. Objective: To evaluate the effect acidifying on productive performance, blood intestinal pH, morphology broilers. Methods: 1,400 one-day-old chicks were used two pH levels (4 6) during three periods (1-21, 1-28, 1-42 days age). The treatments consisted with a blend formic acid (31...
