Copper sulphate and copper sulphide (CuS) as supplements for growing pigs

Copper sulphate and copper sulphide (CuS) as supplements for growing pigs.

The growth-promoting effect of the addition of 0.1 % copper sulphate (supplying 250 p.p.m. copper) to a growing-pig diet, reported by Barber, Braude, Mitchell & Cassidy (1955), has since been widely confirmed. The mode of action of Cu is unknown, and whether the site of action is enteric, systemic or both remains obscure. In an attempt to throw some light on this problem, a study was made of th...

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...

Copper Sulphate and Disinfection of Water

lime, which, added in even so small an amount as 0 000426 gramme to a hundred cubic centimetres of water, kills all the micro-organisms within two hours. The bacteria appear to be acted upon much more promptly than the other organic matter present. For the removal of the excess of the agent the addition of sulphite of sodium (0 000209 gm.) suffices, and an excess of this substance up to 50 per ...
