We sell feed grade minerals to feed millers and premixers
Resco is continuously growing and as a result of this we recently partnered up with a worldwide leader in minerals, in order to bring their products to the market of animal feed. Supplementing animal feed with minerals has been proven to be beneficial in many ways. Resco’s trace minerals are therefore of the highest standards, ensuring the quality of your products. Therefore we are looking to deliver our minerals to feed millers and premixers that provide those quality products.

Cobalt Carbonate 46% 52%
Cobalt Sulphate Heptahydrate ACF quality 21 %
Cobalt Sulphate Monohydrate 33 %
Cobalt plays a role in the development of vitamin B12 and is an essential trace element for ruminants, which can synthesize vitamin B12 (NRC, 1980 and 1989). Furthermore, cobalt can increase fiber digestion of low quality forages (Lopez-Guisa and Satter, 1992; Zelenak et al., 1992). A deficiency can reduce fertility, decrease conception rate and cause an overall subpar conditioning of the calve (Puls, 1994). FEEDAP (2009 and 2012) concludes that “the potential cobalt supplementation to diets for ruminants (…) should be maintained.”
Calcium Iodate Anhydrous 63 %
Calcium Iodate Monohydrate 62 %
Potassium Iodide Stabilized 69 %
Iodine is known to be an important factor in the energy metabolism of cells, in the growth and in brain development in animals (Mc Dowell, 2003; Underwood and Suttle, 2001). Furthermore, it has an influence on the development of the fetus (Puls, 1994) and the conception rate (Yasothai, 2014). Iodine supplementation to food producing animals like poultry (Čepulienė et al., 2008) also plays an important role in battling iodine deficiency in humans (Flachowsky, 2007).
Sodium Selenite 45 %
Selenium supplementation improves conception rate (McClure et al., 1986) and reduces the incidence of retained placenta, mastitis, metritis (Puls, 1994) and white muscle disease (Gerloff, 1992). Furthermore, selenium deficiency is also known to cause abortions, embryonic fetal loss, poor fertility and overall weaker calves (Yasothai, 2014). Selenium in combination with vitamin E reduced calf death losses and slightly increased calf weights (Spears et al., 1986; Gerloff, 1992). In sheep improvements in growth and fertility are most likely (Wichtel, 1999). For poultry, Surai (2002) concludes that “aduaquate Se supplementation is considered to be a crucial factor in maintaining the high productive and reproductive characteristics of commercial poultry”. Furthermore, Surai and Fisinin (2014) indicate the important role of selenium in the fertility of breeding stock and on improving hatchability through the reduction of oxidative stress. Lastly, in a 2015 review Habibian (et al.) finds that selenium supplementation has numerous positive effects on heat stressed poultry.
Zinc oxide 72 % 75 % 78 %
Zinc is an essential nutrient for animals involved in many biochemical reactions. This means that a zinc deficiency has various negative effects including reduced growth and an increased susceptibility to infection (Miller, 1970). Perry (et al., 1968) found that zinc supplementation leads to an increase in daily gain for fattening beef cattle. Also in poultry zinc has numerous major effects on, among others, antioxidation, production and stress related problems (Naz et al., 2016). A 2009 review (Sahin et al.) finds that dietary zinc in poultry is required for a normal immune function and proper skeletal development and maintenance. While Abd El-Hack (et al.) also describe the effect of improved fertility, feathering and appetite in his 2017 review.
Copper Sulphate 24 %
A copper deficiency in cattle is mostly linked to reproductive problems such as early embryonic death (Miller et al., 1988), increased chances of retained placenta (O’ Dell, 1990) and delayed or depressed estrus (McChowell and Hall, 1970). Furthermore, Engle and Spears (2000) showed that copper supplementation in beef cattle decreased cholesterol and alters fatty acid composition, both with possible health benefits for humans. It should however be noted that copper poisoning in cattle as an effect of supplementation to battle a deficiency is becoming more prevalent. As such a proper measuring of the supplementation is crucial (López-Alonso and Miranda, 2020). Just like in beef cattle, a lower yolk cholesterol concentration was found in the eggs of copper supplemented chickens (Balevi and Coskun, 2004) and in the meat (Samanta et al., 2011). Dietary Cu may also be beneficial for production performance in poultry (Samanta et al., 2011).
