Transition Milk Powder

Calf Defender is a transition milk powder designed to be fed after colostrum in the first 7-10 days of a calf’s life before moving on to milk replacer. However, it can be used throughout the entire milk feeding period. It is based on 100% all milk protein with the highest quality skim milk powder together with a health package designed to get the calf off to a good healthy start.


Calf Defender has a higher oil to protein ratio more closely resembling that of cow’s milk. 


Calf Defender contains high levels of Bio-Start powder which is rich in specific polyclonal antibodies, probiotics, and prebiotics. Polyclonal antibodies are designed to protect the gut lining from a range of harmful bacteria and virus. Probiotics/Prebiotics provide beneficial bacteria but also stimulate their growth to maintain a healthy balance in the calf`s gut. Calf Defender also contains high levels of mannan-oligosaccharides (derived from yeast cell walls) which have been shown to remove bad bacteria and toxins and in so doing enhance the immune response in the calf. Biocox contains a blend of essential oils with its primary role to control growth of undesirable organisms linked to calf scour and also enhance the immune system.
