Cattle and sheep are actually poor converters of grass protein into milk and meat. When grazing ordinary grass, livestock use only about 20% of protein from the herbage for production – most of the rest is wasted in faeces and urine. This is not only financially costly, but also detrimental to the environment. A major reason for these losses is the imbalance between readily available energyand protein within the grass. Proteins are rapidly broken down when feed enters the rumen. However, when the diet lacks readily available energy, the rumen microbes can use less of the nitrogen released from the feed, so much of it is absorbed as ammonia and eventually excreted. Grass cell walls consist of the complex carbohydrates, cellulose, hemicellulose andlignin. Although these components can be broken down, this takes time and the carbohydrates are not, therefore, available early on, when grass protein is broken down in the rumen. Water soluble carbohydrates in grass are the sugars found inside the plant cells, rather than in the cell walls themselves. They become a source of readily available energy soon after forage enters the rumen, allowing rumen microbes to process more grass protein. This protein can then be used in the production of meat and milk.
Through this mechanism, Aber HSG varieties, with high levels of water soluble carbohydrates, can significantly improve the utilisation of protein in grass.
Research at IBERS has shown that Aber HSG varieties have consistently higher levels of sugars than standard varieties throughout the grazing season. Water soluble carbohydrate levels up to 50% higher have been recorded in some Aber HSGs. Several trials involving dairy and beef cattle, as well as sheep, have demonstrated significant performance benefits from feeding Aber HSG varieties.
