Ideally, the positive effect of acidifier is to control the balance of gastrointestinal microflora, stimulate the performance of digestive enzymes, improve the digestibility of feed and the appearance of poultry production. Optimizing the function of the digestive tract as the gate of nutrient feed absorption need to be maintained in order to obtain maximum chicken productivity. Poultry feed will be digested, absorbed and metabolized in the digestive tract. Some components greatly affect the performance of the digestive tract such as digestive enzymes, bile acids, pH, feed flow rate, microflora balance and so on. These component changes will affect the structure of the digestive tract and the level of feed digestibility. Giving antibiotics as one effort to maintain the condition of the digestive tract by controlling the balance of microflora and stimulate chemical compounds in the digestive tract of poultry.
Utilization of antibiotics in animal feed has been used since 1946 with the aim to improve the productivity and health status of livestock. In poultry, antibiotics are used with the aim of improving the digestibility of feed, egg growth and production, improving feed conversion, suppressing death and maintaining health conditions. But along with the prohibition of the use of antibiotics as a driver of growth in some countries around the world need to find a solution to mensubsitusi use of antibiotics in poultry feed. Probiotics, prebiotics, organic acids, essential oils, plant extracts and enzymes as feed additives have been used to substitute the use of antibiotics. In this article will explain the use of organic acids as poultry feed additive to maintain the condition of the gastrointestinal tract.
The term organic acid is a chemical compound of a group of fatty acids having a pH below 7 or acidic. However, in terms of animal feed more specified again the function that the use of organic acids aims to preserve feed (feed preservation) and control the pH of the digestive tract (acidifier). In this article we will discuss the use of organic acids as an acidifier for poultry. The term acidifier is also still contradictory among researchers. Some researchers say that the acidifier is used to lower the pH of the gastrointestinal tract but on the other hand the researchers conclude that the acidifier is used to control the pH in the gastrointestinal tract because if in a condition where the pH of the digestive tract is optimum, the acidifier will not work to lower the pH as it will cause the atmosphere pH that is too acidic and causes indigestion and imbalances of intestinal microflora.
There are two types of organic acids sold in the market are single organic acids and complex organic acids. Each product has almost the same function of maintaining the condition of the digestive tract and increasing poultry productivity. However, the products sold are not pure organic acids but are mixed with salts to adjust the pH of the digestive tract. The use of single organic acids and cocktails in the feed will show different results depending on the type of organic acids used, the organic acid origin, the amount of organic acid given, the composition of feed and the condition of livestock
