“…Genetic selection for growth and feed conversion ratio increased the final body weight and performance (Decuypere et al,2005;Olkowski et al, 2008); this was accompanied by the insufficiency of oxygen supply to the tissues in rapidly growing broiler chickens (Huchzermeyer, 2012;Wideman et al, 2013;Hasanpur et al, 2015). This could be as a result of the enhanced cardiac output and the reduced oxygen content of blood, the increased production of red blood cells and hematocrit value; these were consistent with the results of the current study (Decuypere et al, 2005).…”

This experiment was conducted to determine the effects of the diet physical form, Mash (M), Pellet (P) and Extruded (E) on the growth performance, carcass characteristics and metabolic disorders ascites (AS) and as well as sudden death syndrome (SDS) in the broiler chickens. In this respect, feed intake (FI), weight gain (WG) and mortalitywere recorded throughout the experiment and biochemical parameters, hematology and carcass characteristics were tested at 35 and 42 days of age respectively. The results showed that with the increase of the average daily weight gain (ADWG) (p<0.01), the relative breast weight to the carcass weight (p<0.05), better feed conversion ratio (p<0.01), the lower relative cecum weight and gizzard to the carcass weight (p<0.05) were observed by applying the E diet form, as compared with the other treatments. A significant increase in the average daily feed intake (ADFI) was also observed by using the P diet form (p<0.01). Hematological parameters including hemoglobin (Hb), hematocrit (HCT), urea, uric acid, triglyceride, the ratio of low-density lipoprotein to high-density lipoprotein (LDL/HDL), very low-density lipoprotein (VLDL), enzyme activities of aspartate aminotransferase(AST) and alanine aminotransferase (ALT) of the blood serum were lowered by applying the M treatment, as compared with the other treatments (p<0.05). The results indicated that the performance and carcass characteristics were improved by the E and P diet forms; also, with raising the hematology parameters in these treatments, the mortality of ascites and SDS was increased.

“…Ascites syndrome (AS) is called to a metabolic disorder in broiler chickens that a great deal of fluids, originated from blood plasma, accumulates in the abdominal cavity or pericardium spaces (Wiedman et al, ). It is frequently seen in meat‐type, rapid‐grower chickens which are allowed to achieve their maximum growth potential (Druyan et al., ; Huchzermeyer, ). This is because of the inherent inefficacy of cardiopulmonary system of AS‐susceptible chickens in provision of the ever‐increasing demand for O 2 (Lister, ; Wideman et al., ; Van As et al., ; Huchzermeyer, ).…”

“…Therefore, it is, to some degree, under the control of genetic factors. This means that even within a pure line, there are some families which are considerably resistant, while some others are extremely prone to develop AS (Wideman and French, ; Druyan and Cahaner, ; Druyan et al., ; Pavlidis et al., ; Druyan, ; Huchzermeyer, ). This is also because of some exogenous factors that trigger the onset of AS (Hassanzadeh, ; Druyan, ; Huchzermeyer, ).…”

“…Although there is no consensus about the origin of AS in broilers which are reared at sea level, the most probable mechanism of the syndrome was illustrated more recently by Huchzermeyer () and Wiedman et al, (). Shortly, the effects of endogenous and exogenous factors, alone or in combination, cause hypoxaemia and hypercapnia in the bird's body and these changes, in turn, enforce the body metabolic pathways to begin some compensatory reactions.…”

In recent few years, there have been some attempts to find a reliable indicator trait as a selection criterion against susceptibility to ascites syndrome (AS). Blood parameters were of great interest as they could be measured in live animals without implementing an ascites-inducing challenge (AIC). In this work, the suitability of some blood parameters was evaluated for diagnosing AS-susceptible chicks in later steps of the disease in trial 1 as well as their early predictive ability in trial 2. In the first trial, one hundred 1-day-old chicks from two pure broiler lines namely S1 and S2 and, in the second trial, 226 1-day-old chicks from line S2 were subjected to AIC. Saline drinking water (1200 mg/l) and lower-than-standard ambient temperatures were the implemented AICs in trials 1 and 2 respectively. The blood parameters including pH, partial pressure of O2 (pO2 ), partial pressure of CO2 (pCO2 ), bicarbonate ion concentration (BIC), percentage of haematocrit (HCT) and saturated haemoglobin (SaO2 ) were measured twice per each bird at days 28 and 35 in trial 1 and once in trial 2 at day 21. The results of the first trial revealed that in line S2 some of the blood parameters differed significantly between the ascitic and non-ascitic groups following exposure to AIC. In this line, the incidence of AS was accompanied by a lower pO2 , SaO2 and BIC, while with higher pCO2 and HCT values. In the second trial, however, although almost all of the parameters showed meaningful differences between the ascitic and non-ascitic broilers, only mean difference of BIC parameter was statistically significant. The general conclusion of this study is that the blood parameters can somewhat have diagnostic ability in the condition in which the AIC is already present, whereas the results did not approve their usefulness as early predictors of AS.
