“…In this study, the in situ‐in vitro (Calsamiglia and Stern, 1995) and the in vitro (McNiven et al., 2002) procedures were applied in order to reduce the cost and unpredictability of surgically treated animals, as well as to consider animal welfare issues, associated with the in situ methods. In general, both IDRUP and IDDP values for legume seeds were in the range of those reported by other authors (Cros et al., 1992b; Goelema et al., 1998). When both techniques were compared, without considering the values corresponding to lupin, a significant relationship between IDRUP estimated by the Calsamiglia and Stern (1995) and the McNiven et al.…”

“…Previous studies concerning rumen degradability of legume seeds are scarce, with the exception for lupin (Aufrère et al., 2001; Remond et al., 2003; Solanas et al., 2005) and, to a lesser extent for beans (Cros et al., 1992b; Goelema et al., 1998; Sanz Sampelayo et al., 1999). The available information indicates high variability, which can be ascribed in part to methodological differences such as animals and feeding conditions, bag pore size, rumen outflow rate used, sample preparation etc.…”

“…To our knowledge, for vetch and bitter vetch, the information available is limited to acid detergent soluble nitrogen values (Aguilera et al., 1992). For lupin (Cros et al., 1992a; Goelema et al., 1998; Solanas et al., 2005) and beans (Cros et al., 1992b; Goelema et al., 1998), high values for IDRUP (from 0.83 to 0.96) and higher than 0.95 for IDDP have been reported using the mobile bag technique in cows.…”

Chemical composition, rumen degradability and the effect of particle losses, and intestinal digestibility of protein by using in situ-in vitro and in vitro techniques were stated for beans (Vicia faba), lupin (Lupinus albus), vetch (Vicia sativa) and bitter vetch (Vicia ervilia) and four diets including those legume seeds. In addition, the apparent digestibility of experimental diets was determined in goats. The legume seeds showed high protein content (206-319 g/kg dry matter). Effective degradability of protein for legumes and diets varied from 0.80 to 0.87 and 0.76 to 0.82, respectively, decreasing to 0.53-0.76 and 0.61-0.67, respectively, when particle loss was taken into account. Different intestinal digestibility values were obtained with both methodologies without significant relationship between them (y = 1.058-0.463x; R(2)=0.068; RSD = 0.140; p = 0.53). There were no differences in the apparent nutrients and energy digestibility among diets (p > 0.05). These legumes can supply rapidly degradable protein for microbial protein synthesis and contribute to the pool of amino acids available for the synthesis of milk protein and for retention in the body.

The aim of this study was to determine the effect of selected bean cultivars with different levels of anti-nutritional substances on performance and metabolism of dairy cows. In the current twelve-week-long study, 32 dairy cows at 3 to 6 weeks after parturition were divided into four groups. Diets were balanced to have an analogical content of crude protein and energy. Experimental groups (MI, ME, MET) were mixed to the milking concentrate consisting of 20% bean seeds (MI -MISTRAL cultivar with a low content of anti-nutritional substances; ME -MERKUR cultivar with high content of anti-nutritional substances; MET -MERKUR cultivar with technologically reduced the amount of anti-nutritional substances). Clinical evaluation of dairy cows' health and feed intake showed no negative effect of the bean supplementations. Energy, nitrogen and mineral metabolisms were not impaired either. No significant differences were found between groups in milk performance (daily milk yield, protein and lactose production) during the study.On the basis of these results, the bean can be used in 20% in the milking concentrate of dairy cattle. Health risks associated with anti-nutritional content of the native bean are not significant for high-producing dairy cattle. Bean, metabolism, milk performance, reproduction, anti-nutritional substancesBean seeds (Faba vulgaris Moench., syn. Vicia faba L.) are important sources of proteins used in diets of farm animals. Globally, the bean and lupin are grown on the smallest acreage among all pulses. In our climate, beans are used mainly as a fodder crop. Bean seeds contain on average 30-34% crude protein (CP), 6-7% fibre, 47-51% N-free extract (NFE), 33-40% starch, 0.9% ether extract (EE), and 3.3-3.7% ash. When compared to soybean, bean has lower lysine and arginine values (17.6 g·kg -1 vs. 25.5 g·kg -1, respectively) and a low content of sulphur amino acids (6 g·kg -1 vs. 13.3 g·kg -1 of feed ration's dry matter) (Cerioli et al. 1998). Protein and starch degradability of the bean can be influenced by technological treatment. Aleksić et al. (1999a) tested the protein degradability of faba beans in the rumen of cannulated lactating cows. The rate of protein degradability was determined as more than 47%. Aguilera et al. (1992) reported lower degradability of protein by heat treatment (120 °C for 30 min) of bean compared to untreated bean. Benchaar et al. (1992) studied the effect of extruded bean, representing 45% of the feeding ration protein content, on digestion of nitrogenous substances and starch in the rumen and small intestine. The percentage of degradable protein in the intestine was 38% in extruded bean as compared with 33.5% in untreated bean. Cros et al. (1991) came to a similar conclusion and they found that adding extruded bean seeds to diet increases intestinal availability of proteins from the feed. The effect of bean heat treatment on amino acid composition was studied by Cros et al. (1992). Dairy cows fed heat-treated beans showed better utilization of amino acids in the sma...

BACKGROUND Faba bean varieties with low or zero tannin content have been developed in Canada to overcome the negative effects of condensed tannins on the utilization by ruminants of crude protein (CP) and starch. However, their nutritional value has not been evaluated for incorporation in dairy rations. The objectives of this study were to investigate (i) the chemical profile; (ii) the Cornell Net Carbohydrate and Protein System (CNCPS) protein and carbohydrate subfractions; (iii) the energy values; (iv) the ruminal, intestinal, and total digestibility of CP; (v) the metabolizable protein (MP) supply to dairy cows; and (vi) the protein‐inherent molecular spectral characteristics of brown‐seeded (var. Fatima) faba beans with high tannin content and yellow‐seeded (var. Snowbird) faba beans with low tannin content. RESULTS The results revealed that Fatima beans had higher (P < 0.001) CP content than Snowbird (324 versus 295 g kg−1 dry matter (DM)), and lower (P < 0.01) starch content than Snowbird (411 g kg−1 DM versus 444 g kg−1 DM). Fatima had a lower (P = 0.001) soluble subfraction (201 g kg−1 DM versus 220 g kg−1 DM) and higher (P < 0.05) slowly degradable fiber‐bounded (24.9 g kg−1 DM versus 14.7 g kg−1 DM) and non‐degradable (3.24 g kg−1 DM versus 0 g kg−1 DM) CNCPS CP subfractions than Snowbird. Fatima had higher (P = 0.03) MP content (117 g kg−1 DM versus 111 g kg−1 DM) and metabolizable energy content (ME) 3.12 Mcal kg−1versus 3.10 Mcal kg−1) than Snowbird. Molecular spectral intensities of amide I and II proteins (height and area) of Fatima were higher (P < 0.05) than those of Snowbird, reflecting their higher CP content. The ratio of protein spectral intensities, the amide I : amide II height ratio, and the α‐helix : β‐sheet height ratio differed (P < 0.05) between the two types of bean, highlighting differences in their inherent protein molecular structures. CONCLUSION The (Fatima) faba beans with high condensed tannin content had higher MP and ME content. On average, both Faba beans had higher ME and MP content than barley grains, highlighting their promising nutritional value for dairy rations. © 2021 Society of Chemical Industry.
