"I supplement my replacement heifer program with Ngahiwi Calf Milk Replacer and Whey Milk Replacer. I have never had any calf health problems and find the milk mixes readily and the calves love it. My heifers reached their target weight much earlier and cheaper than previously"

John Hathaway
Businessman and Dairy Farmer (Reporoa)

"I rear over a thousand calves a year and always use Ngahiwi to supplement a liquid whole milk rearing program. I like the product, service and good value of their powder. All that you need - a premix, prebiotic, probiotic and coccidiastat, is in the powder. No need to buy expensive extras."

Blair Snelling
Calf Rearer and Beef Farmer (Maungatapere)

"I have used Ngahiwi Calf Milk Replacer for 20 seasons rearing thousands of calves in that time. Ngahiwi mixes easily and my young calves thrive. Ngahiwi contains, as standard, prebiotics, probiotics and a coccidiastat. Excellent product!"
