This video from the My Forage System channel explains good practices for applying acid to hay in order to control heat production and maintain the quality of the fodder.
Key points:
Acid is used to limit the aerobic decomposition of hay. This decomposition produces heat, which can damage proteins and reduce the nutritional value of hay.
The amount of acid to be applied depends on the humidity of the hay. The wetter the hay, the more acid is needed.
It is important to distribute the acid well on the hay. Uneven application may result in areas of overheating and mildew.
Acid application should be done prior to hay storage. This allows acid to soak into the hay and protect it during storage.
The video features research that demonstrates the impact of acid application on heat production and hay quality. The results show that the application of acid can significantly reduce heat production and maintain the nutritional value of hay.
The video concludes by stressing the importance of properly applying acid to hay. Proper application can improve the quality of hay and extend its shelf life.
Here are a few more details from the video:
The accumulation of heat degree days is an important indicator of heat production in a haybale.
Relative humidity in the air is another important factor to consider when applying acid.
Applying acid is more effective on round bales than on square bales.
It is important not to exceed the recommended dose of acid, as this can damage the hay.
