Maintaining the digestive system is one of the keys to the success of poultry farming, both in broilers and layers. Chicken with a poor digestive tract will cause health problems and of course reduce the performance of a good digestive tract.
Necrotic enteritis (NE) is a disease that attacks the digestive system of chickens, which is triggered by the increasing population of Clostridium perfringens bacteria types A and C. “A sub-clinical form of NE causes digestive system disorders while the clinical form causes a more serious problem, namely death," explained Product Manager of Pharmaceutical PT Agrinusa Jaya Santosa (AJS), Endah Soelistyowati, in the 18th MIMBAR TROBOS Livestock The Series with the topic 'NE Disease and its Management' on Wednesday ( 16/6) via the Zoom application and broadcast live via Agristream TV's Youtube channel and TROBOS Livestock Facebook.
At the event, which was initiated by TROBOS Livestock Magazine, prepared by TROBOS Communication (TComm), and sponsored by PT Agrinusa Jaya Santosa together with PT Vaccido Satwa Nusantara, and PT Medion Farma Jaya, Endah said that the close relationship of NE with the digestive system makes practitioners in the field understand the main functions of the digestive system. Two main functions are as the absorption of nutrients and body defense. The digestive system that functions to absorb nutrients consists of three kinds because the incoming feed cannot be directly absorbed by the chicken's body. “First, the feed must be made into molecules first or broken down into small parts. Second, from the small part, it can be absorbed and circulated throughout the body. The third is the disposal of residual substances from the breakdown of the feed molecules," he explained.
Based on the experience of the Production Team of PT Mustika Jaya Lestari of Semarang Region, Central Java, Nur Hidayat revealed that NE (Necrotic Enteritis) caused by Clostridium perfringens is an anaerobic bacterium which means it does not like oxygen. “In the early stages of NE infection in chickens, it is known that there is mild inflammation in the intestines. So, we must first know the mild symptoms, never letting it get severe before being treated," he said. Clostridium perfringens is actually a normal bacteria in the intestines of chickens. However, there are several factors that can trigger these bacteria to be harmful to chicken health. Clostridium perfringens is a normal bacterium in the digestive tract, which can be found in the jejunum, ileum, and colon.
Clostridium is found normally in soil, litter, and feces. As Endah has previously explained, NE can occur if the population of Clostridium perfringens types A and C increases. Abnormal changes in the intestinal environment will change the metabolism and the amount of Clostridium perfringens. “When intestinal conditions are normal, the number of bacteria and metabolism of Clostridium perfringens will be normal. However, when there is an abnormal change in the intestinal environment, the bacteria will change metabolism and produce toxins that were not previously produced. With changes in the intestinal environment, these bacteria will produce toxins and increase their numbers,” he said.
