Improving broiler performance and feed efficiency by adding organic acid to broiler diets [electronic resource].

Includes references.

The current study aimed to evaluate the effect of dietary supplementation of 3 types of organic acids as citric, lactic, and propionic acid with the 3 different levels. 0.5%. 1.0% and 1.5% on the performance of broiler chicks. As well the effect on some strains of intestinal bacteria, intestinal histomorphology, and serum biochemistry of were studied. Three hundred day-old Ross broiler chicks were divided into ten treated groups which were fed on control and nine organic acids - supplemented diets as 3 organic acids types hy 3 levels for each acids. The chicks were placed in floor pens and fed on two basal diets as starter (22% protein. 3000 k Cal/kg) and grower (20% protein, 3000 k Cal/kg). Body weight gains of broiler chicks improved clearly due to inclusion different types of organic acids, especially al 1.5%, propionic acid. Feed consumption values or chicks fed dietary organic acids were higher than control either cumulatively (0-6 wecks of age) or at different intervals (0-3. 3-6 weeks of age). Cumulative feed conversion ratios were improved with inclusion organic acids into broiler diets. the best was recorded for the chicks fed 0.5% lactic acid or 1.5% propionic acid.
