Grass Seed Mixtures
RWN Grass Seeds Mixtures are designed specifically for UK dairy farms. The RWN Grass Seeds Range includes the best grass seed varieties available and aims to maximise nutrition, reduce feed cost and improve the profitability of UK dairy farming.
The introduction of outstanding new Grass and Clover seed varieties has led to major opportunities to improve efficiency and profitability on UK dairy farms. In the last 10 years development of new grass seed varieties has lifted yields by 20% and D-Values by 10%. New white clover seed varieties are 50% higher yielding and are 10% more persistent under UK agricultural conditions.
If you haven't reseeded for a while you could easily be losing 30% in feed output per acre and having to make good the deficit with extra fertiliser and costly concentrates.
Quality forage forms the basis of any high yielding dairy diet
Modern grass seed varieties, especially the new High Sugar Grass Seed varieties developed at IGER are much higher yielding than existing grass seed varieties, more importantly they are nutritionally far superior.
Aber HSG grass seed varieties are higher in digestibility, more palatable and have particular advantage in grazing swards. Dairy cows, graze better, waste less and produce higher milk yields.
Since the launch of the first Aber HSG variety, AberDart, a considerable number of further improved HSG perennial and hybrid high sugar ryegrasses, have been introduced.
Dairy cows waste less grass and give more milk on Aber HSG grazing mixtures
The Aber High Sugar Grasses (HSG) are the result of several decades of focused research, field trials and animal performance testing at IGER (now IBERS). IGER based in Aberystwyth is the worlds foremost grass and clover seed breeding centre. The HSG grasses have the advantage that they have been bred specifically for UK conditions.
The HSG varieties are consistently higher in both sugars and in digestibility than other grass varieties on the NIAB list. In addition they offer extremely high yields with excellent disease resistance and persistency under UK conditions. That said they are now widely grown overseas with over 20,000 ha of HSG grasses having been sown in New Zealand.
The only genuine High Sugar Grass varieties bear the Aber HSG logo and have been demonstrated to be higher in sugar than the first HSG grass Aber Dart.
As dairy nutritionists we formulate our Grass Seed Mixtures with maximum nutrition in mind. One unit of D-Value is equivalent to around one litre of extra milk yield. The perennial high sugar rye grass varieties are clear leaders and form the basis of RWN Grass Seeds Mixtures which are formulated specifically for UK dairy farms.
The new high sugar grass seed varieties are higher yielding than other varieties, they have excellent persistency and disease resistance and most importantly are extremely high in energy with very high digestibility and are nutritionally far superior to other grass seeds.
There has never been more reason for dairy farmers to reseed
RWN Choice Grass Seed Mixtures
The RWN Choice Range of grass seeds offers an extremely cost effective solution where there is a requirement for very high yielding, short and medium term leys which are used predominantly for cutting.
The Choice range includes Italians, Hybrids and Perennial Ryegrasses, both diploid and tetraploid and is especially suited for mixed arable farms where leys are regularly rotated with other crops.
This range also offers some very useful options for overseeding. With the introduction of new improved grass seed harrows, drills and cultivators, regular overseeding is rapidly growing in popularity as a means of boosting grass output.
Very high yielding grass at very low cost
RWN HSG Grass and Clover Seed Mixtures
- Grass and Clover Seed Mixtures developed specifically for UK dairy farms
- Formulated for Maximum nutritional value, digestibility, sugars, yield, persistency, and disease resistance
- Designed to the highest possible specifications using only the best grass seed varieties available
- Include the best new Aber High Sugar Grass seed varieties
- RWN HSG Grass Seed Mixtures are designed for better animal performance compared with conventional grass seeds
- Higher milk yields, improved growth rates, lower costs, higher profits
RWN HSG Grass and Clover Seed Mixtures are formulated to the best quality available. Our range is based on Aber HSG Grass and Aber White Clover varieties bred specifically for UK farm conditions.
IBERS Aber High Sugar Grass seed varieties have been shown to produce up to 2.5 litres more milk per cow than conventional rye grass reseeds.
IBERS Aber White Clover varieties can produce 50% more yield than traditional white clovers and are much more persistent even under high nitrogen regimes.
High Sugar Grass Varieties
Sugar, an excellent source of fermentable energy for rumen microbes is often deficient in UK dairy cow and livestock diets. Our long term grazing mixtures are based on Aber high Sugar diploid ryegrasses. These are more palatable and more digestible and are grazed down to lower residuals resulting in much better grass utilisation.
In addition diploids are typically 3% - 6% higher in dry matter than tetraploids which allows grazing cows to achieve higher dry matter intakes than with most tetraploids. Aber High Sugar Grasses have been shown to produce up to 2.5 litres more milk per cow than conventional rye-grass reseeds.
In addition protein utilisation has been shown to be improved by up to 25%. Availability of high sugar bought-in feeds, at competitive prices is limited. The most cost effective source of sugar for dairy and livestock diets, is the sugar from home grown High Sugar Grasses, either grazed or conserved as silage using an effective inoculant.
RWN HSG Grass Seed mixtures are formulated to maximum D-Value and Sugar levels as well as exhibiting extremely high yields, disease resistance and persistence.

There has never been more reason for dairy farmers to reseed
White clover has a D-Value 5 - 10 units better than the best perennial ryegrasses as well as being much higher in protein and being at it's best in late summer when grazed grass quality is deteriorating.
Aber White Clover seed varieties can produce 50% more yield than traditional clovers and are much more persistent even under high nitrogen regimes.
A mixed grass / clover sward, without the need for nitrogen, applications can produce 75% of the forage dry matter yield of an all grass sward receiving 300 units of nitrogen.
Grass / Clover at the same level of nitrogen can produce up to 13% more DM yield and up to 3.5 litres more milk per cow per day. Download the Aber White Clover Management Guide.
RWN HSG Grass Clover Seed Mixtures can generate up to £500/acre more profit per acre over the life of a ley compared to other seed
