Feeding molasses to a dairy cow helps the rumen function and ultimately the digestibility of the other feeds the cow is eating. So it's not just the benefit of the molasses; it helps get more from the other feeds as well.
Molasses is a good laxative for poultry and flushes out toxin or poison from the digestive system, especially in cases of poisoning. It is also rich in minerals such as calcium, potassium, and magnesium.
You can also use it for day-old chicks for the first 3 days during introduction in the brooder, as it is a rich source of energy.
However,take care not to overdose, as it can be dangerous because it can cause diarrhea, leading to dehydration.The correct amount would be 1 liter of mollases in 10 liters of water, or 100 ml of mollases in 1 liter of water.
