“…The same could be observed for other animal species such as sheep [125] and pigs [126,127]. In a group of sheep fed with husks, at least a slight increase in the nitrogen retention could be proven [125]. Rubio et al [128] have not been able to find any effect from the inclusion of husks or autoclaved husks in the feed of broiler chickens compared to husk-free feed.…”

“…In growing broiler chickens, it was shown that the addition of tannins to the basic feed significantly reduced protein digestibility and that this effect increased with increasing tannin content [151,152].

From harvesting to consumption of the faba bean (Vicia faba), different plant residues such as stems, leaves, pods, and seed husks remain as by-products. The harvest residues constitute about 50% (w/w) of the whole aboveground biomass, while the empty pods and the seed husks account for 11% and 6% (w/w) on average, respectively. Due to the environmental and dietary benefits, the global production of faba beans is most likely to increase in the future. Concomitantly, the amounts of by-products will rise as well. So far, mainly the harvest residues have been widely studied, whereas the pods and husks have received less consideration. Therefore, the aim of this review was to provide an overview of the composition of the faba bean plant residues and to illustrate their potential of being used as feedstock in food, feed, or even non-food applications. This literature survey clearly reveals that all the residual materials of faba beans contain valuable compounds and might be suitable for a multitude of different applications. The residual material should thus not be disposed of but further valorized in order to exploit the full potential of the biomass.

“…In addition, the use of whole plant faba bean silage as a forage source has been tested and the potential was proved (McKnight and MacLeod 1977). However, the study to test the nutritional value of faba bean partitions is limited, only one study has been conducted by Minakowski et al (1996) about faba bean hulls and suggested that the inclusion rate should not exceed 20% of the diet.…”

To our knowledge, there is limited study on the relationship between the molecular structure of feed and nutrient availability in the ruminant system. The objective of this study is to use advanced vibrational molecular spectroscopy (attenuated total reflection [ATR]–Fourier transform infrared [FT/IR]) to reveal carbohydrate molecular structure properties of faba bean partitions (stem, leaf, whole pods [WP], and whole plant) and faba bean silage before and after rumen incubation in relation to nutrient availability and supply to dairy cattle. The study included the correlation between carbohydrate‐related spectral profiles and chemical profiles, feed energy values, Cornell Net Carbohydrate and Protein System carbohydrate fractions, and rumen degradation parameters of faba bean samples (whole crop, stem, leaf, WP, and silage) before and after rumen incubation. FTIR spectra of faba bean sample before and after 12 and 24 h rumen incubations were collected with JASCO FT/IR‐4200 with ATR at mid‐IR range (ca. 4000–700 cm−1) with 128 scans and at 4 cm−1 resolution. The univariate molecular spectral analysis was carried out using OMNIC software. The results show that ATR–FT/IR spectroscopic technique could detect the change of microbial digestion to carbohydrate‐related molecular structure. The spectral parameters of feed rumen incubation residues had a stronger correlation with less degradable carbohydrate fractions (neutral detergent fiber, acid detergent fiber, acid detergent lignin, hemicellulose, and cellulose) while spectral profiles of original faba samples had a stronger correlation with easily degradable carbohydrate fractions (starch). In conclusion, rumen degradation of carbohydrate contents can be reflected in the change of its molecular spectral profiles. The study shows that vibrational molecular spectroscopy (ATR–FT/IR) shows high potential as a fast analytical tool to evaluate and predict nutrient supply in the ruminant system.
