Narbon vetch (Vicia narbonensis) grain was used at the level of 10, either raw (R) or autoclaved (T), in isonitrogenous starter (0 to 28 days) or grower (29 to 56 days) diets. At 4 weeks, half of the chicks raised on the R starter diet continued on the R grower diet (RR) and half were shifted to the T grower diet (RT). At the same time, half of the chicks raised on the T starter diet continued on the T grower diet (TT) and half were shifted to the R grower diet (TR). At 4 weeks of age, the cumulative weight gain (CWG) of chicks on raw vetch was significantly lower (P0.01) than that of chicks on the control of corn-soybean meal diet or on the autoclaved vetch diet. The CWG of chicks (from 29 to 49 or 29 to 56 days) on the raw vetch grower diet (groups RR and TR) was significantly (P0.01) lower than of chicks on the autoclaved vetch (groups TT and RT) and on the control (CC) grower diets. Cumulative feed consumption (CFC) from the start of the trial until 4, 7 or 8 weeks of age, tended to be lower for chicks offered the raw vetch diets. No adverse effects were observed on the health of chicks that could be attributed to the use of raw or treated vetch.Narbon vetch can be used in substituting part of soybean meal in broiler diets. Autoclaving is an effective method for denaturation of anti-growth factors in Narbon vetch.
