[QUOTE="RPGalloway, post: 753409, member: 14152"] One possibility to consider is an iodine deficiency. A heifer calf has the greatest need for iodine to develop in utero. A deficiency can be caused by overfeeding of legumes which will cause a high ratio of bull calves. If an animal is iodine deficient, it does not matter what mineral program you are using, they will not be assimilated properly. until the iodine requirements are met. Iodine requirements are not very high, usually feeding some kelp / seaweed will remedy the problem. Using an inorganic form of iodine (potassium iodide) can be toxic in excess. Kelp is high in iodine in a natural state. One of the simplest warning signs of a iodine deficiency is dandruff. You can do a blood test, but it will usually only show a large deficiency. Iodine needs are increased during cold weather and feeds high in oxalates or nitrates such as legumes. Selenium deficiency will raise the need for iodine also. Brad [/QUOTE]
