What is the Explanation of steaming up in animal production?

Steaming up in animal production refers to the practice of increasing the nutritional and energy intake of pregnant animals, particularly dairy cows, in the weeks leading up to calving. This process aims to enhance fetal development and prepare the animal for lactation, ultimately improving milk production post-calving. Proper steaming up can help prevent metabolic disorders and ensure that the animal has sufficient body condition and energy reserves to support both the pregnancy and subsequent lactation.
