W.  aEffect of size of grind and level in the ration of dehydrated alfalfa meal, of trace minerals and an implanted tranquilizer on the performance of fattening lambs.  c1960  aResearch was conducted to determine the effect of size of grind of dehydrated alfalfa meal, level of dehydrated alfalfa meal and the addition of trace minerals and vitamin B12 to a pelleted feeder lamb ration consisting of 60% roughage, 32% ground yellow corn, 7% soybean oil meal, 1% bone meal, 0.5% iodized salt and vitamin A and D. The size of grind of the dehydrated alfalfa meal (3/64?, ¼? and ½?) had no effect on performance of fattening lambs, except that the hemoglobin level was significantly higher (P&lt0.05) for lambs fed the %4? grind of dehydrated alfalfa meal in their pellet (12.21 gm. %) than for lambs fed either of the two coarser grinds in their pellet (11.64 gm. %). Lambs whose pellet contained 40% dehydrated alfalfa meal and 20% ground corn cobs gained significantly faster (P&lt0.05) than those whose pellet contained 20% dehydrated alfalfa meal and 40% ground corn cobs. Carcasses from lambs fed the 40% level of dehydrated alfalfa meal in their pellet graded significantly higher (P&lt0.01) than those from lambs fed the 20% level. The addition of the trace minerals, manganese, cobalt, copper, iron and zinc and of vitamin B12 had no overall effect on growth rate or level of hemoglobin. However, castrate males fed the trace minerals and B12 gained significantly more than the females on the same ration. The subcutaneous implantation of a 10-mg. pellet of trifluomeprazine, either at the start of the trial or on the 42nd day of the trial, resulted in a statistically significant increase in gain (P&lt0.05). A 5-mg. implant had no effect. None of the tranquilizer treatments tested had an apparent effect on carcass quality.  aAnimal feeding  aAnimal nutrition  aCarcass composition  aDrugs  aLambs  aPelleted feeds  aSheep  aMedicago Sativa  aFattening  aGrowth rate  aMineral nutrients  aNeuroleptics  aNutrient drug interactions  aTrifluomeprazine1 aHOLZ, R.
