Effects of feeding ervil (Vicia ervilia) seeds soaked in water or acetic acid on performance and internal organ size of broilers and production and egg quality of laying hens

Experiment 1 was conducted to study the effects of feeding 60percent untreated ervil seeds (UE) or ervil soaked in water at room temperature (RTWE) or at 40°C (40WE) for 72 h with water change every 12 h on the performance and internal organ size of broilers. Isocaloric and isonitrogenous corn-soybean meal diet (control) and diets containing 60percent UE, RTWE, or 40WE were fed to battery caged broilers in 4 replicates with 8 birds per replicate, from 8 to 49 d. Broilers consuming UE from 8 to 28 d gained less weight, used feed less efficiently, and had heavier liver, pancreas, and gall bladder weights (percentBW) than the other treatments (P 0.05). Compared with control birds, broilers on 40WE had similar relative organ weights, except for kidney, but lower BW gain at 49 d (P 0.05). In experiment 2, ervil seeds were soaked in 1percent acetic acid at room temperature (RTAAE) or at 40°C (40AAE) for 24 h. A conventional diet and diets containing 60percent UE, 40WE, RTAAE, or 40AAE were fed to individually caged laying hens in 4 replicates per treatment with 5 hens per replicate for 42 d. Hens on UE had the poorest performance followed by RTAAE, 40WE, and then 40AAE (P 0.05). Compared with the control, all treated ervil diets resulted in lower shell thickness values but higher Haugh unit scores (P 0.05). In experiment 3, 30percent dietary UE and 40AAE at 10, 20, and 30percent were fed to layers for 56 d. The general performance of hens on 30percent 40AAE was comparable with that of the control except for BW and feed conversion (P 0.05). Compared with UE, the performance of broilers and layers was improved by 40WE and that of hens was further enhanced by 40AAE. In addition, diets containing up to 20percent 40AAE had no adverse effects on feed conversion, egg production, or quality of hens. ©2005 Poultry Science Association, Inc.
