I received a call recently, a producer was having good lambs that were still on the ewe just tip over and die. After questioning, we discovered he had recently added lick tubs to the lot and the lambs really liked them.
I suggested removing the lick tubs among other possibilities. He did and today he called back and said as soon as he removed the tubs the lambs quit dying.
Classic urea toxicity. There are two practices I thoroughly dislike in the sheep business, one is minerals containing phosphorus and the other is lick tubs.
Corn and soybean oil meal are always cheaper than molasses and urea and obviously safer. Lick tubs and tanks provide profit for the seller and a false sense of security and the easy way out for the producer. They are not the right choice.
