Fluid retention stomach8/9/2023 Due to poor hygienic conditions on the farm, conditions for the proliferation of pathogenic microorganisms in the environment and feed were favourable. The genetic cause of ascites herein might be excluded, since the growth of the broilers was much lower compared with the standard growth performance of Cobb 500. In this study, ascites could be attributed to a microbial cause, most probably Salmonella sp. or E. This trial result demonstrated that diet supplementation with the acidifier Biotronic® SE represents a solution to alleviate the effect of ascites on broiler farms. In the Biotronic® SE group, the mortality rate increased 37.27% over the mortality rate prior to the ascites outbreak, compared to 72.90 and 41.25% respectively in the Negative control and Positive control groups. On Day 42 an outbreak of ascites was observed on the broiler farm with typical ascitic symptoms such as gasping, cyanotic combs and wattles, depression, extended abdomens, and increased mortality rates up to 7.53, 5.26 and 3.81% in the Negative control, Positive control and Biotronic® SE groups respectively. The incidence of ascites in chickens was confirmed by postmortem examination.įor the initial 42 days, the broilers did not show any obvious clinical signs of ascites, even though on Day 35 mortality rates were recorded in the Negative control, Positive control and Biotronic® SE groups as 2.04, 3.09 and 2.39% respectively (Table 1). Improvements in growth performance and decreases in mortality rates, as well as benefits in alleviating ascites in chickens have been observed in recent trials with BIOMIN’s acidifier product Biotronic® SE.Īscites incidence was characterized by clinical signs (panting, gurgling sounds, cyanotic combs and wattles, excessive abdominal fluid accumulation) and mortality rates. Of course, optimal management practices are also very important for reducing the problem of ascites and maximising performance of broilers. In the case of ascites caused by microorganisms, recent studies investigating the effect of feed supplementation with acidifiers have shown promising results. Feed restriction is only of economic benefit when the incidence of ascites is very severe. However, reducing feed intake decreases broiler growth performance. Slower growing birds have reduced oxygen needs allowing the cardiopulmonary organs (heart and lungs) to keep up with oxygen demands of the birds. In the case of ascites caused by genetics, feed restriction might reduce the effect of the disease. Making efficient use of natural resourcesįirstly, it is important to understand the underlying causes of an ascites occurrence on a poultry farm.
