چکیده

Two hundred and forty male Cobb broilers were used to study the reasons of causing ascites. The results showed that cold ambient temperature could induce ascites (33.89% vs. 2.50%) and significantly increase triiodothyronine (T3), but reduce thyroxine (T4) concentrations in plasma (p<0.05). The ascitic broilers had high concentrations of aldosterone and K , but low concentrations of T3 and T4 in the plasma (p<0.05). The lower body weight and higher relative heart, lung and liver weight of the ascitic broilers demonstrated the metabolic disarrangement. When ascites occurred, hematocrit in blood increased significantly (p<0.05). The mash feed could reduce body weight and the onset of ascites, compared with the pellet feed.

Genetic Perspective of Ascites Syndrome in Meat-Type Chickens

Pulmonary hypertension syndrome (ascites) is a metabolic disorder in fast-growing broilers. Inconsistency of oxygen requirement and the cardiovascular ability make the birds susceptible to ascites. Incidence of ascites was accompanied by right ventricular hypertrophy, fluid accumulation in the abdominal cavity and finally mortality. The objective of the current study was to review the genetic b...

Effects of Various Type of Bentonite (Montmorillonite) on Ascites-Related Physiologic and Metabolic Factors in Broilers

This study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. Two hundred and seven days old Arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (SSB); 3) basal diet + 1% non-processed sodi...

Endogenous and environmental factors interactions that contribute to the development of ascites in broiler chickens: a review

The increasing susceptibility of broiler chickens to ascites syndrome has coincided with a continuing genetic and nutritional improvement in their feed efficiency and growth rate. Ascites is multifactorial and interactions between environmental and endogenous factors play a particularly important role. The selection of fast growing broilers for high feed efficiency, which is characterized by hy...

Hepatic and cardiac oxidative stress and other metabolic changes in broilers with the ascites syndrome.

The objective of this study was to evaluate the gluconeogenic response of in vitro stimulated hepatocytes from control broilers and broilers with clinical manifestations of the ascites syndrome. The basal rate of glucose synthesis from lactate was found to be threefold greater in sick birds than in the control group and stimulation obtained with epinephrine was found to be quantitatively simila...
