“…[15][16][17] However, there is no reveal any references to previous works on the antioxidant activity of other Onobrychis. The aim of our study is to evaluate in vitro total phenolic content and antioxidant activity of the methanolic extracts from three Onobrychis species (O. sosnovskyi, O. viciifolia and O. melanotricha) and assess any correlations between total phenolic content in the extracts and their antioxidant activities.…”

“…In other studies on O. viciifolia extract by different solvents, the following chemical composition were found: the phenolic glycosides; kaempferol and quercetin, sucrose; the inositol [(+)-pinitol]; L-tryptophan, several flavonol glycosides and a mixture of condensed tannins. [15][16][17]34,35 Ince et al assessed total phenolic acid content of different extracts (methanol, acetone, distillation water and ethyl ethanoate) of O. viciifolia using Folin-Ciocalteu method and reported its amount between 11.35 ± 0.82 to 38.26 ± 0.15 μg Tannic acid/g of dry extract. 17 In the case of the O. viciifolia, the extractable compounds by acetone and methanol solvents had higher yield in comparison with ethyl ethanoate and distillation water solvents.…”

“…The biological activity of tannins was assessed by the method of radial diffusion using bovine serum albumin (BSA) medium (Hagerman and Butler, 1978). As sainfoin contains no hydrolysable tannins (Marais et al, 2000), the amount of CTs was considered to be equal to the total tannins Parasitological techniques Four days after weaning, rabbits in groups IC and IS were orally infected with 2125 infective, third-stage larvae (L3) of T. colubriformis. This date was counted as D0 of infection.…”

Alternative strategies to synthetic chemical drugs are needed in livestock and are a key issue in organic farming today. This study aimed at examining the potentialities of sainfoin, a legume rich in condensed tannins, as a nutraceutical that combines nutritive and antiparasitic effects in rabbits. To test the effect of infection with a helminth (I: infected groups; NI: not infected groups) and the effect of substituting 40% of the alfalfa in a control diet (C) with sainfoin (diet S), four groups of 16 weaned rabbits were arranged according to a 2 × 2 bifactorial design. The sainfoin diet differed from the control by its tannin concentration (1.8% v. 1.0% tannic acid equivalent) and its ADL concentration (84 v. 43 g/kg). For each diet, 16 rabbits were infected with 2125 thirdstage larvae of Trichostrongylus colubriformis. Growth, feed intake, feed conversion ratio and nematode faecal egg counts (FECs) were controlled for 6 weeks. A digestibility trial was performed. After necropsy, adult worms and eggs in utero per female were counted and egg-hatching rate calculated. Growth tended to be lower for S groups than for C groups (38.2 v. 39.5 g/day; P = 0.06). Feed intake was higher for S groups compared with C groups (+5.2 g dry matter/day; P < 0.01), as was the feed conversion ratio (3.2 v. 2.9; P < 0.001), probably in relation to the dietary ADL level. Protein digestibility was reduced in S groups compared with C groups (−6.0 points; P < 0.001), probably associated with the effect of the tannin concentration. Digestibility of hemicelluloses was reduced in infected rabbits compared with non-infected ones (−5 points; P = 0.01). Using the substitution method, the digestible energy of dehydrated sainfoin pellets used as raw material was calculated at 11.12 MJ/kg and digestible proteins at 110 g/kg. The infection did not produce any clinical signs of digestive disorders. No differences were observed according to the diet, neither in the number of adult worms (972; P = 0.50), the number of eggs in utero per female (14; P = 0.95), nor FEC (400 eggs/g; P = 0.57). In contrast, the rate of faecal egg hatching in the S group tended to be lower than in the control (58.3% v. 85.2%; P = 0.08). In conclusion, sainfoin seems to fit nutritive requirements for rabbits, supplies a large quantity of fibre and particularly lignins, and limits the development of nematode eggs in faeces.

“…The tannin effect assessed by PEG addition showed a less-marked decrease for sainfoin OMD than for sulla. The CT in sainfoin and L. pedunculatus are known to have a similar structure and to be more reactive than the CT of L. corniculatus and sulla (Marais et al, 2000;Min et al, 2003).…”

In vivoandin situdigestive characteristics of sainfoin (Onobrychis viciifoliaL., a tannin-rich forage) and lucerne (Medicago sativa L., a tannin-free forage) were compared to evaluate the effects of condensed tannins (CT) and growth stage (vegetativev. early flowering) in experiment 1. In experiment 2, the hays of the two forages, harvested at early flowering, were compared. Ingestibility, organic matter digestibility (OMD) and nitrogen (N) retention were measured in sheep fed sainfoin and lucerne fresh forages and hays. The loss of dry matter (DM) and N from polyester bags suspended in the rumen, abomasum and small intestine was also measured using rumen fistulated sheep and other intestine fistulated sheep. Nitrogen content was lower in sainfoin than in lucerne. Content of CT in sainfoin decreased with growth stage (3.5 to 2.5 g CT/kg DM) and was lower for sainfoin hay (0.6 g CT/kg DM). Ingestibility and OMD did not differ between fresh-fed forage species. Total N tract digestibilityin vivowas much lower for sainfoin than for lucerne fresh forages (mean value 0.540v. 0.721,P< 0.001) and for sainfoin hay than lucerne hay (0.464v. 0.683,P< 0.001). In both species, N digestibility was not altered by growth stage. The rumen degradation of N was lower in sainfoin than in lucerne, resulting in a lower proportion of N intake excreted in urine. The intestinal digestibility of sainfoin was also lower than that of lucerne, resulting in a higher N excretion in faeces. Hence the efficiency of N utilisation by sheep (ENr) was similar (mean value 0.205 and 0.199 g N retained/g N intake for fresh sainfoin and lucerne, respectively). The coefficient of N retention by the animal was higher for sainfoin at the vegetative stage than for all the other forages. Nitrogen degradability in the rumen determined by the nylon bag technique (DegN) was lower for sainfoin than for lucerne when forages were studied both fresh (mean value 0.608 and 0.818, respectively) and as hays (0.631 and 0.767). The efficiency of forage N digestion (ENd) was higher for sainfoin at the vegetative stage. Compared with lucerne, sainfoin greatly increased thein situestimate of forage N escaping the rumen but decreased its intestinal digestibility.
