Here is the lamb formula recipe I recieved from my mentor. She uses it on all of her bottle lambs and it's cheaper than the store bought stuff. It is supposed to be from a sheep rancher in Australia originally. I use it and for me it has worked fine. Thought I would pass it along use it or don't at you own discretion. I actually pour out about 3 1/2 to 4 cups of the whole milk to get it all to fit. Sorry about the typo from earlier. homemade lamb replacer Instructions Things You'll Need: â¢ 1 gallon whole milk â¢ 2 cups buttermilk â¢ 1 can evaporated milk â¢ whipping cream â¢ baking soda 1. Step 1 2. Pour 3 cups of the milk out of the gallon jug. I have to dump almost four out to get it all to fit. 3. Step 2 4. Now pour in the evaporated milk and the buttermilk. 5. Step 3 6. Fill the rest of the jug with the whipping cream. By whipping cream I mean the stuff you buy in the quart container that's essentially straight cream. Shake well. You're done!

The baking soda acts as an antacid, to help neutralize the PH in case of sour stomach. â¢ â¢ Once your babies are a few weeks old, make the transition from warm milk to cold. The producer I learned this from raises over 1000 sheep a year, and typically has around 200-300 bummer lambs. He said that when they switched from warmed milk to cold, their mortality rate from bloat dropped from 15% to about 1%. With my own flock, my lamb mortality rate dropped to 0%. As cold milk takes longer to sour and ferment, it makes sense that it would reduce the incidence of bloat.
