Copper Enhances Performance of Pigs
نویسنده
چکیده
Copper is a unique mineral, When it is added to pig diets at a high level (much higher than the nutritional requirement), copper stimulates growth and feed efficiency much like antibiotics do. This effect is particularly evident with young pigs. Table 1 shows results of UK studies over a 1 &year period in which high copper diets were fed to weanling pigs (from 17 to 40 lb). Copper increased growth rate by 12.3%, feed intake by 8.3% and feed efficiency by 4.8%. The same type of response occurs in growing and finishing pigs, to a lesser extent (Table 2). Today, copper is commonly used as a growth stimulant, particularly in pig starter feeds.

Effects of copper sulfate and ferrous sulfide on performance and liver copper and iron stores of pigs.
Three experiments involving 296 pigs were conducted to determine the related effects of copper sulfate and ferrous sulfide on performance and liver copper and iron stores of growing-finishing pigs, and the effect of ferrous sulfide on the depletion of copper from the liver. The dietary addition of 250 ppm copper alone improved growth rate by 9.2% (621 vs 678 g/day) and feed to gain ratio by 3.3...

Two cooperative experiments were conducted by the North Central Regional Committee on Swine Nutrition. Ten stations participated and utilized 125 pens (802 pigs) in experiment l to evaluate the effect of high dietary copper levels and vitamin E on performance, hemoglobin level and liver copper stores of pigs. In experiment 2, 142 pens (934 pigs) were used to evaluate the effect of different lev...

Copper slag (CS) is an abrasive blasting grit made of granulated slag from metal smelting processes. As copper slags are known to be waste material and cause a lot of environmental problems, it would be a good idea to use them in different sections of industry such as pavement construction. On the other hand, in order to save energy and reduce the amount of pollutants re...

A total of 225 pigs (PIC 327 × 1050, initially 25.5 lb) were used in a 21-d trial to evaluate the effects of copper source and level on nursery pig growth performance. Pens of pigs were balanced by initial BW and randomly allotted to 1 of 5 dietary treatments with 9 replications per treatment. The 5 corn and soybean meal-based diets were arranged in a 2 × 2 + 1 factorial with main effects of co...
متن کاملEffect of chelated copper sources on performance of nursery and growing pigs.
Four experiments were conducted to determine the effect of Cu source and level and an antimicrobial agent on performance of nursery (6 to 25 kg) and growing (20 to 65 kg) pigs. Copper was fed either as CuSO4.5H2O (CS), inorganic chelated Cu (ICC) or organic chelated Cu (OCC) to provide 31.25 to 250 ppm supplemental Cu. In Exp. 1, 224 pigs were used to study Cu source and level added to nursery ...
