Silage and Haylage
| Question | Answer | Article | |

| What is the typical dry matter (DM), metabolisable energy (ME), and crude protein (CP) range of silage and haylage? |
{ |
Link to Article | |
| What are the characteristics of these feeds? | Silage is a fermented crop with a low dry matter content. It is cut at a relatively early stage of development and stored under anaerobic conditions. Haylage is similar to silage but is often cut at a more mature stage. It typically has a higher pH and DM than silage and can often be of more variable quality. With horses haylage is typically preferred (by owners) to silage.

Urea
| Question | Answer | Article | |
| Is this feed classified as a i) forage; ii) root, tuber or their by-product; iii) cereal or their by-product; or iv) protein concentrate & source? | This feed is classified as iv) protein concentrate & source, but this is a misnomer as technically it is not a protein, but an indirect source.

| What is the crude protein (CP) content of this feed? | The CP is 2,900 g/kg DM.
|
Link to Article | |
| What are the characteristics of this feed? | In ruminants, the rumen microflora hydrolyse urea to ammonia. Urea is often supplemented to diets of low protein concentration and can also be contained in molassed vitamin/mineral blocks. Urea may be used to treat straw (urine sometimes used in some developing countries), where it effectively improves digestibility of this low quality roughage.
|
Link to Article | |
| What concerns are associated with this feed? | Less than one-third of the dietary nitrogen should be provided as urea in order to minimise ammonia toxicity. Signs of ammonia toxicity include bloat, twitching, ataxia, excessive salivation and death.
