Feeding farm formulated milk replacer to Holstein x Kankrej crossbred calves can lead to better feed efficiency, lower feeding costs, and reduced disease incidence compared to using commercial milk replacer or whole milk. Calves fed the formulated milk replacer had lower dry matter intake but higher feed conversion efficiency, resulting in lower overall feeding costs and better weight gain. This approach can be a more economical and healthier option for farmers, as it allows for more milk to be available for human consumption while still ensuring the health and growth of the calves.
