Evaluation of a copper lysine complex and copper sulfate in weanling and finishing pigs, and the effect of copper supplementation on circulating growth hormone and IGF-1 levels
The objectives of this research were 1) to evaluate CuS0₄ and a CU lysine complex (CuLys) as growth promotants for weanling pigs, 2) to assess the effects of feeding growth stimulating levels of Cu from both sources on dry matter digestibility (DMO) and mineral balance of finishing pigs, and 3) to …

Analysis of water quality problems in the VPI & SU Duck Ponds and suggested management alternatives
… July of 1988. A pond-treatment program involving copper sulfate was initiated to control algal blooms consisting mainly of the green alga, Chlamydomonas. Based on the complexing properties of the water, such as alkalinity and humics, a copper sulfate dose of 13.6 kg was determined to be a safe and …

Some of the factors affecting the operation of a screw conveyor type mixer
… tests on the mixer were made with chert and copper sulfate to determine the effect of speed of elements, feed rate, feed proportions, and particle size on mixing efficiency. These materials were relatively inexpensive and the copper sulfate was readily leached from the samples to form a basis …

The effects of heavy metals on the asexual reproduction of the annelid Aeolosoma headleyi Beddard (1888)
… Bioassays were conducted with the chloride and sulfate salts of zinc, copper, cadmium, cobalt, and nickel. Additionally, chromium, as potassium dichromate, was tested. Of these metals, only two, zinc chloride and copper sulfate, significantly stimulated reproduction at or below 0.01 ppm of the …
