Agriculture Victoria has recently updated its online resource on grazing crop stubble, providing timely and crucial information for sheep owners. The webpage, titled ‘Sheep Nutritional Requirements When Grazing Stubble’, offers valuable insights into managing variable feed quality to maintain the health of flocks.
Grazing stubble can prove to be an effective source of nutrition for sheep during the summer and autumn seasons. However, it is important to be aware that the feed quality of stubble can vary significantly, necessitating the use of sheep supplements.
One key aspect to consider when grazing stubble is the energy and protein content of the diet. The value of feed in stubble derives from residual grain and the quantity of green plant material, which may include shot grain and summer weeds. Understanding the variability of feed value for different types of stubble, as well as methods to measure it on your farm, is crucial for ensuring the well-being of your flock.
The updated resource not only provides information on the nutritional requirements of grazing on stubble but also highlights potential health issues that sheep may face. These include grain poisoning, nitrate poisoning, lupinosis, thiamine deficiency, water belly, and worms. It emphasizes the importance of ensuring that sheep have full stomachs before introducing them to a stubble paddock. Alternatively, gradual introduction can be done by limiting grazing time or implementing a cell grazing system.
Furthermore, the resource advises that toxic weeds may emerge following summer rain, presenting a risk to sheep grazing on stubble. In general, stock should be removed from the area after six weeks or when grain and green feed fall below 40 kg per hectare.
By grazing on stubble, sheep owners can not only provide their flocks with nutrition but also reduce stubble loads, which will benefit farmers as they transition into the autumn and winter seasons.
In conclusion, the updated resource from Agriculture Victoria offers valuable tips and insights for sheep owners, ensuring the health and well-being of their flock when grazing on crop stubble. Understanding the nutritional requirements, potential health issues, and proper management techniques is crucial for maintaining a healthy and thriving flock.
