“…This within-population variation for CT concentration (range = 37.5 mg/g) was higher compared to that observed in earlier studies that analyzed variation among different sainfoin varieties, where ranges of 24.5, 21.8, and 18.5 mg/g were observed (Azuhnwi et al, 2011(Azuhnwi et al, , 2012Malisch et al, 2015). The benefit of most of the polyphenolic compounds analyzed in the present study is their antioxidant capacity and anthelmintic effectiveness (Thill et al, 2012).…”

ABSTRACT. Sainfoin (Onobrychis viciifolia) is a perennial forage legume with great potential for use in sustainable agriculture due to its low input requirements, good drought tolerance, and production of forage rich in polyphenolic compounds, which are beneficial for animal health. However, its distribution and cultivation are limited due to its moderate agronomic performance and a general lack of well adapted, highly yielding cultivars. Faster progress in breeding is imperative, but is often hampered by the complex inheritance of traits and limited knowledge on the genetic composition of this tetraploid, outbreeding species. Molecular genetic tools might aid phenotypic selection; however, to date no information on marker-trait associations is available for sainfoin. Hence, the goal of the present study was to detect marker- trait associations in a biparental F 1 population. Single plants were screened for recently developed genetic markers and phenotyped for important agronomic traits and concentrations of different polyphenolic compounds. Significant trait-associated markers (TAM) were detected for plant height (11), plant vigor (1), and seed yield (7). These three traits were positively correlated with each other and shared some TAMs. Correlations among markers suggested that two independent loci control these three vigor-related traits. One additional, independent TAM was detected for the share of prodelphinidins in total condensed tannins. Our results provide insight into the genetic control of important traits of sainfoin, and the TAMs reported here could assist selection in combination with phenotypic assessment.

“…Among the test plants of the present study, O. viciifolia is the most researched with respect to ammonia formation. It was found earlier to have clear rumen-ammonia-mitigating properties across various cultivars and harvest dates (Scharenberg et al 2009;Azuhnwi et al 2012;Grosse Brinkhaus et al 2016).…”

Mature herbs as supplements to ruminant diets: effects on in vitro ruminal fermentation and ammonia production

et al. 2021

Context High concentrations of crude protein in ruminant diets may lead to excessive production of ruminal ammonia, which may stress the animal’s metabolism and impact nitrogen efficiency. This may become a problem in zero-concentrate feeding systems when pasture grass is rich in crude protein. Polyphenols such as tannins may protect part of dietary protein from ruminal degradation and thus inhibit ammonia formation. Aims The present study screened mature herbs for their potential to mitigate ruminal ammonia formation in cattle, when provided as a supplement to a forage diet. Methods Thirty-five temperate-climate, herbaceous meadow plant species (including three legumes) that appear in biodiverse natural and sown pastures were investigated for their effects on ruminal ammonia production. Aboveground material was harvested during ripening of the seeds and analysed for nutrient and phenol concentrations. Net energy and protein absorbable at the duodenum were calculated. Incubations (24 h) with cattle rumen fluid following the in vitro Hohenheim Gas Test protocol were performed to compare the effects of the test plants on ruminal gas and ammonia formation. Test plants replaced one-third of a basal mixture consisting of 57% Lolium perenne L. and 43% Medicago sativa L. (air-dry-matter basis). Results were compared with those obtained with the basal mixture alone. Key results According to regression analysis, ammonia concentration after incubation was negatively related to concentrations of total extractable phenols and total tannins in feed mixtures, whereas the relationship was weakly positive with dietary crude protein. In 23 and 19 of the test diets, respectively, in vitro gas production (indicating ruminal organic matter digestibility) and ammonia concentrations in the incubation medium after 24 h were significantly lower than with the basal mixture alone. Incubations containing Galium verum L., Leontodon hispidus L., Lotus corniculatus L., Onobrychis viciifolia Scop., Plantago lanceolata L., Sanguisorba minor Scop. and Scabiosa columbaria L. maintained gas production and estimated in vitro organic matter digestibility while at the same time lowering ammonia concentrations. Conclusions Seven mature herbs of a screening of 35 proved to have potential for positive effects on ruminal protein utilisation without impairing fermentation. Implications These herbs are of particular interest as dietary supplements for dairy cows grazing protein-rich pastures.

“…As a consequence of the apparent differences in agronomic performance and CT concentration associated with genetic stock, many researchers have begun their studies by first obtaining seeds from globally diverse populations (Azuhnwi et al., , ; Bhattarai, Coulman, Fu, Beattie, & Biligetu, ; Carbonero, Carbonero, Smith, & Brown, ; Gea, Stringano, Brown, & Mueller‐Harvey, ; Goplen, Howarth, Sarkar, & Lesins, ; Hatew et al., , ; Hosaininejadmir, Jafari, & Nakhjavan, ; Jafari, Rasouli, Tabaei‐Aghdaei, Shanjani, & Alizadeh, ; Lorenz, Carbonero, Smith, & Udén, ; Malisch et al., ; Mohajer et al., ; Prospéri, Demarquet, Angevain, & Mansat, ; Rasouli, Jafari, Tabaei‐Aghdaei, & Shanjani, ; Thill et al., ; Zarrabian, Majidi, & Ehtemam, ). This reflects an attempt to rapidly enhance research efforts on sainfoin by utilizing advanced techniques, in part due to new interest in potential environmental and animal health benefits.…”

Sainfoin (Onobrychis viciifolia) is a forage legume of renewed interest in western Canada, with equally weighted advantages and disadvantages. In agronomic attributes, sainfoin is, at best, equal in yield, crude protein content and persistence to alfalfa (Medicago sativa). Sainfoin is equally or more palatable than alfalfa to ruminants, with comparable levels of animal productivity per unit forage consumed. The advantages it has compared to alfalfa include the following: (a) mitigation of frothy bloat; (b) reduced ammonia emissions (more faecal nitrogen (N) and less urinary N); (c) equal or better N retention by ruminants; and (d) anthelmintic protection from intestinal parasites. These advantages may be attributed to the presence of condensed tannins (CT), in legumes such as sainfoin. Emphasis on agronomic characteristics in breeding programmes appears to have led to the inadvertent reduction in the efficacy of CT characteristics. Persistence of sainfoin appears to be dependent on minimal pressure from competing plants, harvest or grazing, and good growth conditions from mid‐summer into fall, allowing for adequate root reserves for survival. It is possible that judicious use of glyphosate in late season might lessen competition in that critical period as sainfoin is more glyphosate‐tolerant than alfalfa. Otherwise, sainfoin may be best considered a short‐lived forage and best adapted for early season harvest or grazing to eliminate the risk of bloat.
