Zinc metabolism was studied in Zn-deficient and control Holstein calves over a 2-mo period following a single oral or i.v. 65Zn dose. In both orally and i.v. dosed animals, all gastrointestinal tissue sections from Zn-deficient animals contained more

Eighty female Holstein calves were used to examine the effects of high amounts of added dietary Fe as ferrous carbonate on performance of young dairy animals. Experimental starters containing either 0, 500, 1000, 2000, or 4000 ppm supplemental Fe as

The metabolism of a single oral zinc-65 dose was studied in young dairy calves fed two concentrations of added A1 (0 and .20% A1) and two concentrations of added P (0 and .22% P) for 7 wk. The four treatments were 1) normal P-low A1, 2) low P-low A1,

Zinc-65 was injected directly into various sites throughout the small intestine of Holstein calves fed a low zinc diet. Zinc absorption was determined by comparing zinc-65 content of blood, liver, kidney, lung, heart, pancreas, rib, muscle, and other

Chloride deficiency signs were produced in young Holstein calves by a low chloride diet (.063% chlorine) and daily removal of chloride in abomasal contents. General clinical signs included anorexia, weights loss, lethargy, mild polydipsia, and mild p
