Your calf has all the symptoms of being exposed to the insecticide imidacloprid during development in the womb. He has an obvious underbite, a definitive symptom of Imidacloprid exposure. Imidacloprid concentrations in the spleen of the exposed newborn results in their cells not being able to produce normal levels of heat and energy, resulting in lethargy. The damage to the spleen from imidacloprid results in damage to the digestive system and consequently disrupted immune system function according to studies. I would suggest that you go to a health food store and get a small bottle of the Hyland's Homeopathic cell salt called Calc. Phos. 6X or if they have it, Calc. Ph 30X is even better. Put one tablet of the Calc. Phos. in the bottle of milk (after warming the milk) each time you feed the calf. Calc. Phos. is a really effective electrolyte. It stimulates the cells of the calf to uptake the minerals the cells need to function. That will help the calf to have normal energy levels and be able to digest its food more efficiently. The calf's underdeveloped facial bones should also grow to be normal in length in two or three weeks. The calf will then be able to graze normally and efficiently, so will have normal weight gain. Calves with an underbite have trouble biting off foliage efficiently resulting in less weight gain than calves with a normal bite. When I suggested to my neighbors that they give their calves with underbite and lethargy, baby goats with underbite, that couldn't stand up and walk after they were born, or horse foals with underbite, the Calc. Phos. tablet at least three times a day, if drinking their mother's milk or at each feeding if bottle fed, all of the newborns had normal energy levels within two days and all had their underdeveloped upper jaw bones grow to normal in two weeks. The sooner the Calc. Phos. tablets begin to be given after the youngster is born, the sooner its energy levels and ability to digest its food are stimulated to work at normal levels. Got to my website (
www.judyhoy.com) and under where it says Explaining the use of homeopathic cell salts, it says click here to read. There are several before and after photos of young animals that had their cells stimulated to work at normal levels.
