“…Cocultivation of forage legumes with companion crops can deliver higher total yields (Nyfeler et al, 2009;Döring et al, 2013;Finn et al, 2013;Mora-Ortiz, 2015;Hunt et al, 2016;Malisch et al, 2017), more nitrogen fixed per hectare (Nyfeler et al, 2011;Vasileva and Ilieva, 2016) and improved dry matter and nitrogen digestibilities of coensiled mixtures (Wang et al, 2007), but success depends on the agronomic compatibility of the species, appropriate treatments, and development of new sainfoin cultivars with a more competitive canopy (Mora-Ortiz, 2015; Mora-Ortiz and Smith, 2016; Kölliker et al, 2017;Malisch et al, 2017).…”

Condensed tannins (CTs) account for up to 20% of the dry matter in forage legumes used as ruminant feeds. Beneficial animal responses to CTs have included improved growth, milk and wool production, fertility, and reduced methane emissions and ammonia volatilization from dung or urine. Most important is the ability of such forages to combat the effects of gastrointestinal parasitic nematodes. Inconsistent animal responses to CTs were initially attributed to concentration in the diet, but recent research has highlighted the importance of their molecular structures, as well as concentration, and also the composition of the diet containing the CTs. The importance of CT structural traits cannot be underestimated. Interdisciplinary research is the key to unraveling the relationships between CT traits and bioactivities and will enable future on‐farm exploitation of these natural plant compounds. Research is also needed to provide plant breeders with guidelines and screening tools to optimize CT traits, in both the forage and the whole diet. In addition, improvements are needed in the competitiveness and agronomic traits of CT‐containing legumes and our understanding of options for their inclusion in ruminant diets. Farmers need varieties that are competitive in mixed swards and have predictable bioactivities. This review covers recent results from multidisciplinary research on sainfoin (Onobrychis Mill. spp.) and provides an overview of current developments with several other tanniniferous forages. Tannin chemistry is now being linked with agronomy, plant breeding, animal nutrition, and parasitology. The past decade has yielded considerable progress but also generated more questions—an enviable consequence of new knowledge!

“…The head-space volume of gas produced in each vial was measured after 3, 6, 9, 12, 24 and 48 h, using a water displacement apparatus. Triplicate vials for each substrate were retrieved from the incubator after 6 and 48 h and used to estimate DM disappearance as described by Wang et al (2007). The liquid fraction of each vial was recovered by centrifugation (12,000 × g, 15 min; 4 • C) and the supernatant was used to estimate NH 3 -N and VFA as described above for silage.…”

“…In contrast to the present findings, Turne and Neel (2003) observed an effect of level of quebracho condensed tannin supplementation on lucerne organic matter and fibre digestibility. Wang et al (2007) showed that the OMD of alfalfa-sainfoin mixtures preserved as hay or silage was improved compared with alfalfa preserved alone.…”

The aim of this study was to investigate whether the use of sainfoin-based condensed tannins (CT) enhances feed value when given with tannin-free legumes (lucerne) to sheep. The experiments were conducted with fresh sainfoin and lucerne harvested at two stages (vegetative stage as compared with early flowering) in the first growth cycle. Fresh sainfoin and lucerne forages were combined in ratios of 100 : 0, 75 : 25, 25 : 75 and 0 : 100 (denoted S100, S75, S25 and S0, respectively). Voluntary intake, organic matter digestibility (OMD) and nitrogen (N) retention were measured in sheep fed the different sainfoin and lucerne mixtures. Loss of dry matter (DM) and N from polyester bags suspended in the rumen, abomasum and small intestine (SI) was also measured using rumen-fistulated sheep and intestinally fistulated sheep. The CT content in sainfoin (S100) decreased with increasing percentage of lucerne in the mixture (mean value from 58 g/kg DM for S100 to 18 g/kg DM for S25) and with growth stage (S100: 64 to 52 g/kg DM). OMD did not differ between different sainfoin/lucerne mixture ratios. Sainfoin and lucerne had an associative effect (significant quadratic contrast) on voluntary intake, N intake, total-tract N digestibility, N in faeces and urine (g/g N intake) and N retained (g/g N intake). Compared with lucerne mixtures (S0 and S25), high-sainfoin-content mixtures (S100 and S75) increased the in situ estimates of forage N escaping from the rumen (from 0.162, 0.188 for S0 and S25 to 0.257, 0.287 for S75 and S100) but decreased forage N intestinal digestibility (from 0.496, 0.446 for S0 and S25 to 0.469, 0.335 for S75 and S100). The amount of forage N disappearing from the bags in the SI (per g forage N) was the highest for high-sainfoin mixtures (from 0.082, 0.108 for S100 and S75 to 0.056, 0.058 for S25 and S0, P , 0.001). Rumen juice total N (tN) and ammonia N (NH3-N) values were the lowest in the high-sainfoin diet (mean tN 0.166 mg/g in S100 as compared with 0.514 mg/g in S0; mean NH3-N 0.104 mg/g in S100 as compared with 0.333 mg/g in S0, P , 0.001).Keywords: ruminants, in vivo, condensed tannins, sainfoin-lucerne mixtures. ImplicationsLucerne is favoured for its high yield and nutritional quality, but is seldom grazed in pure stands as it causes bloating. Condensed tannins (CT)-containing legumes do not cause bloating and form CT-protein complexes that are stable and insoluble at rumen pH. Several papers have focused on the effect of CT on the nutritive value of CT-containing forages. The aim of this study was to investigate whether the use of sainfoin CT enhances feed value when given with tannin-free legumes (lucerne). We tested the effects of different sainfoin/lucerne proportions on voluntary intake, in vivo digestibility and in situ ruminal and intestinal digestibility in sheep.
