Underlined titles available on this website.
Please contact Micronutrients for full reports on any of the
following:
- Miles et al (1998; Poultry Science 77:416-425):
- Relative bioavailability for TBCC found to be 106-112%
of copper sulfate.
- No differences between copper sources in toxicity
up to 600 ppm inclusion levels
- TBCC less active than copper sulfate in promoting
oxidation
- Cromwell et al (1998; Journal of Animal Science 76:118-123):
- Three studies concluded TBCC as effective as copper
sulfate in improving growth in weanling pigs.
- Experiment III at United Feeds demonstrated TBCC
to be more effective at 150 ppm than copper sulfate
at 200 ppm
- Dr. Jerry Spears – 1995 Metabolic Study at NC State
University:
- Pigs fed TBCC retained more copper than pigs fed
copper sulfate
- Virginia Scientific Research – 1996 Broiler Performance
Comparison using various levels of TBCC and Copper Sulfate:
- Both copper sources improved Gain and Feed:Gain
significantly over controls
- Birds showed poor performance and data was widely
scattered, obscuring any differences between copper
resources.
- PARC Institute – 1997 Evaluation of TBCC Impact on
Vitamin Loss During Pelleting:
- Vitamins A, E and riboflavin measured higher in
pelleted/crumbled feed with TBCC added than without
- PARC Institute – 1997
Evaluation of TBCC and Copper Sulfate:
- TBCC showed as much improvement in Weight Gain and
Feed Efficiency at 188 ppm inclusion rate as did copper
sulfate at 250 ppm
- PARC Institute – 1999 Study of Effects of Copper
Source on Crop Mycosis and Performance with Coccidia and
Candida Albican Challenge:
- Relative efficacies of TBCC vs. copper sulfate:
Body Weight = 125%, Feed Conversion = 128%, Crop Mycosis
= 135%, Coccidial lesions = 151%, Bioavailability
= 112%
- PARC Institute – 1999
Study of Effect of Copper Source on Vitamin Stability:
- Pelleted feed, serum and liver Vitamin E levels
all improved more with copper from TBCC
- Weight Gain and Feed Efficiency were significantly
better at both 125 and 188 ppm from TBCC than any
level of copper sulfate
- Relative bioavailability for TBCC vs. copper sulfate
= 121.7%
- Copper leaching from stool was less using TBCC
- PARC Institute – 1998 in vitro Antimicrobial Screening
vs. E. Coli, Salmonella and Camplobacter:
- TBCC appeared significantly more discouraging to
microbial growth than copper sulfate
- Dr. Jerry Spears – 1996 Cattle Feeding Study:
- TBCC more available in cattle than copper sulfate
in the presence of molybdenum
