Many parts of Queensland and New South Wales may be experiencing unprecedented hot conditions. This is resulting in a massive reduction of pasture quality and quantity. Australia’s dry seasons and/or dry years result in pastures that have insufficient nutrient levels to adequately grow out cattle to meet customer requirements and this is leading to more animals being introduced to grain feeds at some stage of their lives.
There are three common situations that result in animals being introduced to a grain based diet and they are:
- In a drought ration;
- As a supplement to grazing (grain assist);
- Full feedlotting.
In all of these situations care must be taken, especially on introduction or conditioning to grain feeding. A grain ration should be designed to give maximum weight gains and fattening rates at the lowest cost possible with minimal metabolic issues.
If you are considering putting your livestock onto a grain ration there are a few important details that you need to consider and these are discussed below:
What ingredients to use?
The initial selection of ingredients for your ration will depend largely on what is readily available to you and at the lowest cost possible. When selecting ingredients it is important to look at the quality and quantity. A very cheap source of contaminated grain or silage won’t end up so cheap if you end up losing the majority of your herd to toxicity. You must also be able to adapt the ration as the cost and availability of the ingredients change over time.
How to formulate a ration?
The main thing to focus on when formulating a ration is to remember that all animals require a balanced diet to bring out the best in their genetic potential. A balanced ration requires adequate supplies of:
How to introduce livestock to grain rations?
Stock that are fed grain or any feed with a high carbohydrate content should be introduced gradually to the ration so that the animal’s rumen has time to adapt. Starter rations should not contain any more than about 50% grain and the transition to the final diet should be taken slowly over at least 10-14 days.
How can AgSolutions Help?
AgSolutions has developed the MegaMin Feedlot Enhancer to assist farmers in balancing their grain rations.
