Effects of plant-bound condensed tannin (CT)-containing sainfoin vs. CT-free alfalfa (or low-CT alfalfa-sainfoin mixture), plant stage of maturity, and their interaction on enteric methane (CH4) emissions, diet digestibility, and N excretion were studied, using 8 ruminally cannulated beef heifers in 2 sequential short-term experiments (Exp. 1 and 2). In Exp. 1, first growth legumes were harvested daily and offered fresh to heifers. Heifers were assigned to 100% sainfoin or 80% alfalfa:20…

Impact of condensed tannin-containing legumes on ruminal fermentation, nutrition, and performance in ruminants: a review

The objectives of this review are to summarize information regarding the impact of CT on ruminal fermentation, carbohydrate and protein metabolism, and the potential to identify and select for forages that contain CT for ruminant production.

Methane Production of Fresh Sainfoin, with or without PEG, and Fresh Alfalfa at Different Stages of Maturity is Similar but the Fermentation End Products Vary

Alfalfa and sainfoin are high-quality forages with different condensed tannins content, which can be affected by the stage of maturity, which means fermentation end products were affected both by the chemical composition and CT contents.

Tannin-containing legumes and forage diversity influence foraging behavior, diet digestibility and nitrogen excretion by lambs.

Offering diverse combinations of legumes to sheep enhanced intake and diet digestibility relative to feeding single species, while allowing for the incorporation of beneficial bioactive compounds like condensed tannins into the diet.

In vitro ruminal fermentation characteristics and utilisable CP supply of sainfoin and birdsfoot trefoil silages and their mixtures with other legumes

SF and its mixtures have similar advantages as they show limited proteolysis during ensiling, and appear promising for improving the protein utilisation of ruminants.

Influence of Forage Diversity and Condensed Tannins on Livestock Foraging Behavior, Production and Environmental Impact

Diverse combinations of forages with different nutrient profiles and plant secondary compounds may improve intake and nutrient utilization by ruminants. We tested the influence of diverse dietary

Beneficial Effects of Temperate Forage Legumes that Contain Condensed Tannins

There is great potential value for sustainable livestock production in the use of highly digestible, nitrogen-fixing legumes containing tannins demonstrated to improve ruminant productivity.

Effects of feeding blend-pelleted co-products on nutrient intake, digestibility, and production performance of high producing dairy cows

Replacing soybean meal and canola meal with blend-pelleted co-products did not affect the nutrient intake, digestibility, and production performance in high producing dairy cows.



Effects of grain supplementation on methane production of grazing steers using the sulphur (SF6) tracer gas technique

The objective of the study was to examine the effect of supplemental grain on methane (CH4) production of grazing steers. Eight beef steers (344.6 ± 6.4 kg) were assigned to legume-grass pasture (C;

Methane production from dairy and beef heifers fed forages differing in nutrient density using the sulphur hexafluoride (SF6) tracer gas technique

The effects of cattle breed type and forage quality (high, medium and low) on methane production were measured under ad-libitum and restricted feeding conditions and Methane production was not different between dairy and beef cattle under either level of feeding.

In vivo and in situ measurements of the digestive characteristics of sainfoin in comparison with lucerne fed to sheep as fresh forages at two growth stages and as hay.

Compared with lucerne, sainfoin greatly increased the in situ estimate of forage N escaping the rumen but decreased its intestinal digestibility, which resulted in a higher N excretion in faeces.

Methane emissions from beef cattle: effects of fumaric acid, essential oil, and canola oil.

It is demonstrated that canola oil can be used to reduce methane losses from cattle, but animal performance may be compromised due to lower feed intake and decreased fiber digestibility.

Effect of feeding dehydrated and ensiled tanniferous sainfoin (Onobrychis viciifolia) on nitrogen and mineral digestion and metabolism of lambs

In conclusion, the reduction in ruminal ammonia and urine-N losses by sainfoin CT did not improve N-retention, and Ensiling of sain foin led to the lowest N- retention.

Effect of pregrazing herbage mass on methane production, dry matter intake, and milk production of grazing dairy cows during the mid-season period.

It was concluded that grazing LHM swards would increase grass quality with a concurrent reduction in CH(4) emissions as well as milk output during the mid-season grazing period.

Effects of feeding grass or red clover silage cut at two maturity stages in dairy cows. 1. Nitrogen metabolism and supply of amino acids.

It was concluded that despite the higher total AA supply of cows fedred clover versus grass silage diets, further milk production responses on red clover diets were compromised by an inadequate supply of Met as evidenced by lower Met concentration in the AA profile of omasal digesta and plasma.

Differing effects of 2 active dried yeast (Saccharomyces cerevisiae) strains on ruminal acidosis and methane production in nonlactating dairy cows.

The study shows that different strains of S. cerevisiae fed as active dried yeasts vary in their ability to modify the rumen fermentative pattern in nonlactating dairy cows, and it may be prudent to further evaluate this strain in cattle fed high-forage diets, for which the risk of acidosis is low but CH(4) emissions are high.

Effect of sainfoin on in vitro digestion of fresh alfalfa and bloat in steers

The effects of sainfoin (Onobrychis viciifolia) on digestion of alfalfa (Medicago sativa) were investigated in vitro and in vivo. Fresh alfalfa and sainfoin were incubated in an artificial rumen
