Performance of Broilers and Production and Egg Quality Parameters of Laying Hens Fed 60% Raw or Treated Common Vetch (Vicia sativa) Seeds

Abstract

Two experiments were conducted to study the effect of feeding 60% untreated (U) or coarsely ground treated vetch (V) seeds on performance of broilers and laying hens. In Experiment 1, the V seeds were soaked in 1% NaHCO3 (1:10) or in 1% acetic acid (1:5) at room temperature for 24 h (RTAA). Birds on the NaHCO3-treated V diet had 100% mortality rate but had significantly longer survival time than those on UV (14.9 vs 5.1 d). Birds on RTAA-V survived and had similar BW and feed conversion but greater kidney size than those of the controls at 7 wk of age (P < 0.05). In Experiment 2, control, UV, V soaked in water at 40 C (40WV), RTAA-V, and V soaked in acetic acid at 40 C (40AAV) diets were fed to laying hens for 84 d. The ground seeds in RTAA-V and 40AAV were soaked in acetic acid (1:10) at room temperature or at 40 C, respectively, for 24 h. For 40WV, the seeds were soaked in water (1:10) at 40 C for 72 h with a water change every 12 h. The UV-fed hens ceased egg production within 14 d and had the highest BW loss and the lowest feed intake among all treatments (P < 0.05). The 40WV and 40AAV significantly improved these criteria. Moreover, the RTAA-V resulted in performance comparable to that of the controls. Eggs produced by hens on treated V diets had similar weight but higher Haugh unit score (11 points), thinner shell, and lower yolk color score than those of the controls (P < 0.05). Results indicated that RTAA-V at 60% dietary level was not detrimental to broilers and laying hens.

Retraction: The Effect of Raw and Processed Common Vetch Seed (<i>Vicia sativa</i>) Added to Diets of Laying Hens on Performance, Egg Quality, Blood Parameters and Liver Histopathology

“…In the present study, autoclaving of vetch caused reduction in live weight (−286.22 g), while in another study, Farran et al (1995) reported increase in live weight gain (59 g) in group fed on diet with autoclaved vetch. The findings of the present study were compatible with the results of Farran et al (2001). Farran et al (1995) reported that autoclaved vetch in the proportion of 25% could be used safely in diets.…”

“…Vetch seeds are well adapted to semiarid and arid lands and a cheap source of protein and energy for ruminant and poultry (Lópeze Bellido, 1994). The seeds contain up to 25-30% crude protein, 1-2% ether extract, 5-6% crude fiber and 60% carbohydrate (mainly starch) (Fernandez-Figares et al, 1993;Farran et al, 1995;Abreu and Bruno-Soares, 1998;Farran et al, 2001). However, it contains antinutritional factors (ANF) such as vicine, convicine, β-cyanoalanine and tannin (Cheeke and Shull, 1985;Lallé s and Jansman, 1998;Wiryaman and Dingle, 1999;Darre et al, 1999).…”

“…So it is necessary to establish processing techniques to ensure its optimal utilization. In order to inactivate or reduce anti-nutrients, various conventional, simple processing methods have been used in legume seeds (Barbour et al, 2001;Farran et al, 2001).…”

“…Moreover, the suitable VBM inclusion level (40%) of the present investigation was found to be comparable with that of an earlier report on an under-utilized legume, M. pruriens var. cochinchinensis at 30% (Ukachukwu and Szabo, 2003), M. cochinchinensis at 38% (Ukachukwu, 2007) and Vicia sativa at the 60% level (Farran et al, 2001) as well as the common legume, Cajanus cajan at the 50% level (Amaefule and Obioha, 1998).…”
