Tribasic copper chloride and copper sulfate as copper sources for weanling pigs.
We conducted three 28-d experiments involving a total of 915 pigs to assess the relative efficacy of tribasic Cu chloride (Cu2[OH]3Cl) and Cu sulfate pentahydrate (CuSO4.5H20) in diets for weanling pigs. Experiments 1 and 2 were conducted at an experiment station (University of Kentucky), and Exp. 3 was conducted at a commercial feed company's swine research facilities (United Feeds, Inc.). The...

متن کاملComparison of Tri-Basic Copper Chloride Versus Copper Sulfate on Measures of Forage Utilization and Copper Status in Beef Heifers
The objective of this study was to investigate the effect of supplemental tribasic copper chloride (TBCC) vs Cu sulfate on the Cu status and voluntary forage intake of growing heifers fed forage-based diets. Twenty-four crossbred heifers were stratified by weight and randomly allotted to individual pens. Heifers were provided free-choice access to ground grass hay (8.0 and 54.0% CP and TDN, res...
متن کاملUtilization of copper in copper proteinate, copper lysine, and cupric sulfate using the rat as an experimental model.
One hundred twenty male Sprague-Dawley rats, averaging 108.6 g initial body weight, were used in two feeding experiments to evaluate the utilization of Cu in Cu proteinate, Cu lysine, and cupric sulfate. In Exp. 1, 60 rats were randomly assigned to 12 treatments in a 2 x 2 x 3 factorial arrangement of treatments, with Zn supplementation at 0 or 1000 mg/kg diet, Cu supplementation at 5 or 15 mg/...
متن کاملEffects of tribasic copper chloride versus copper sulfate provided in corn-and molasses-based supplements on forage intake and copper status of beef heifers.
The objective of this study was to investigate the effect of supplemental tribasic copper chloride (Cu(2)(OH(3))Cl; TBCC) vs. Cu sulfate (CuSO(4)) on Cu status and voluntary forage DMI in growing heifers. Two 90-d experiments were conducted using 48 non-pregnant, crossbred heifers (24 heifers/experiment; 355 +/- 10.7 and 309 +/- 9.9 kg for Exp. 1 and 2, respectively). In each experiment, 3 supp...
