“…In agreement with our results, Robblee et al (1977), Muduuli et al (1981), andFru-Nji et al (2007) reported no differences in feed consumption between the control and FB diets. In contrast, Laudadio and Tufarelli (2010) reported decreased feed intake, and Magoda and Gous (2011) reported increased feed intake with increased FB inclusion.…”

“…Muduuli et al (1981) demonstrated that vicine consumption reduced egg weight and increased erythrocyte hemolysis. According to Muduuli et al (1981) vicine may act in following three ways: reduces the amount of precursor material available to the granulosa cells, by damaging granulose cells and hence their activity, or by destroying the ovum. However, Fru-Nji et al (2007) reported that increases in dietary FB content seemed to increase albumen fraction and simultaneously reduce the yolk fraction of the eggs.…”

The study was conducted to evaluate an appropriate inclusion level of locally produced unprocessed or expander-processed coloured flowered faba bean (FB) (cv. 'Kontu') seeds in diets for laying hens. Egg production and egg quality variables were determined with 560 hens (Lohmann Selected Leghorn, LSL Classic) in a 40-week continued experiment. The hens were fed one of the five diets containing soybean meal as the main protein source. A diet without FB was served as a control diet. Both unprocessed and expander-processed FB was tested either in proportions of 50 g kg -1 or 100 g kg -1 in the diet. Faba bean inclusion (control vs. FB diets) had no effect on the egg production rate, egg mass production, feed consumption, or feed conversion ratio, but it decreased egg weight (p<0.05). Dietary FB inclusion tended to increase the mortality of the hens (p<0.10). Faba bean processing had no effects on egg production parameters or hen mortality. Daily egg mass production decreased and feed conversion ratio increased when FB proportion increased (from 50 to 100 g kg -1 , p<0.05). Faba bean inclusion had no effects on egg exterior quality. It can be concluded that 50 g kg -1 of the FB studied (cv. 'Kontu') can be used in the diets of laying hens (LSL Classic) without negative effects on production performance or livability.

“…It may be hypothesized that vicine causes the production of small yolk which results in the production of small eggs. Vicine may act in the following ways: by reducing the amount of precursor material available to the granulosa cells; by damaging the granulosa cells, and hence their activity; or by destroying the ovum (Muduuli et al, 1981). Wyburn et al (1965) suggested that the granulosa cells of the yolk may be involved in the transport of the large quantities of precursor material required to form the yolk and that it may be actively involved in yolk synthesis.…”

“…Serum protein concentration was proposed to be an indicator for reflecting the adverse effect of legume seeds on growth and laying performance (Wyckoff et al, 1983). In another study, Muduuli et al (1981) stated that 1% of vicin in the diet for laying hens didn't change blood plasma protein and increased plasma lipid level (P＜ 0.05).…”

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

Abbreviation Key: C＝control diet not containing common vetch seed, CV＝common vetch seed. This study was carried out to determine the effects of raw and physical processed common vetch seed added to diets of laying hens on the laying performance, egg quality traits, blood parameters and liver histopathology. Lohman layers, 46 wk of age as 6 replicate cages each containing 4 hens, were allocated randomly to one of four dietary treatments. Treatment groups were fed diets containing a standard commercial layer diet (Control), basal diet plus 25% raw common vetch seed (CV), 25% autoclaved (at 120℃ for 30 minutes) common vetch seed (ACV) and 25% roasted (at 130℃ for 30 minutes) common vetch seed (RCV) for 12 weeks. Considering the findings of performance traits, differences among the groups were found significant (P＜0,05); however the effects of treatments were not significant on egg quality and blood parameters. The diets containing raw and different physical processed vetchs reduced feed consumption and egg production.CV compared to the control caused lipid accumulation in hepatocytes, severe congestion of hepatic blood vessels, inflammation, the increased numbers of Kupffer cells and sinusoidal dilatations. Findings from present study pointed out the risk of increased hepatic damage due to use of raw vetch seed. It is also remarkable that increasing treatments of vetch seed lead to decrease of liver damages.The results of this experiment indicated that inclusion of CV and ACV in diet affected adversely performance parameters and hepatic damage in laying hens. Alleviation was observed on laying hens fed on diet including 25% RCV.As a conclusion, it has been determined that 25% RCV is more appropriate to use in diets of laying hens than 25% CV and ACV.
