Piglets supplemented in the early phase of the nursery period with 200 ppb of KemTRACE® Chromium had a 3 to 5-point improvement in feed to gain versus pigs that did not receive supplementation. In addition, chromium supplementation in the early phase provided a 1.6 lb to 2.4 lb final weight advantage over piglets that did not receive chromium supplementation.
In a commercial research facility, the effect of KemTRACE® Chromium on growth performance of weaned pigs was evaluated. Pigs supplemented with 200 ppb of chromium provided a 0.79 lb advantage over pigs that did not receive chromium supplementation.
Sows fed chromium propionate showed a difference in wean weight over the control. This wean weight response was observed again in the second reproductive cycle. Also, during the second reproductive cycle, there was a difference in more live born pigs. In this research trial and in previous research trials (Brennan et al., 2011; Hagen, 2000), supplemental chromium has been shown to improve sow and pig performance. The use of chromium propionate as a management tool in commercial swine production to maximize sow unit performance is supported in the research done to date.
Chromium supplied as a trace nutrient (ppb) has been demonstrated to improve sow reproductive and piglet performance when supplied in gestation and lactation sow diets (Hagen et al., 2000). This study showed that feeding KemTRACE® Chromium improved sow and piglet performance when fed to sows in lactation and gestation at a rate of 200 ppb. The sows produced and weaned more piglets, thus creating a viable economic return to the producers.
A commercial study involving over 65,000 sows was initiated to study the effects of adding 200 ppb KemTRACE® Chromium as a source of chromium in gilt and sow rations. The most notable improvement was a 13.7% reduction in non-productive sow days. During the same period, sow production data showed a steady increase in the average parity in this herd. This response is an indication that sow longevity improvements are in progress.
KemTRACE® Chromium had an impact on feed intake, final body weight, average daily gain and feed efficiency in both thermoneutral and heat stressed pigs compared to pigs fed no chromium. KemTRACE Chromium continues to demonstrate consistent growth improvements when fed to pigs in both thermoneutral and heat stress conditions.
A study was conducted evaluating the effect of feeding KemTRACE® Chromium, KemTRACE® Zinc and ENDOX® Dry antioxidant in combination to finishing pigs in both a thermoneutral and a heat stress environment. In this study, the pigs fed the combination of products as a heat stress pack showed difference in total gain. The high level of response in a short period of time provides indication that the combination of products was an effective intervention to reduce the overall effect associated with heat stress.
Heat stress is a costly issue facing pork producers. Heat stress significantly reduces feed intake, therefore directly impacting growth performance of pigs and profitability. Feed intake isn't the only performance parameter affected. Reduced growth rate, decline in fertility, increased mortality and more non-productive sow days are just a few of the other ways heat stress negatively impacts all aspects of pork production.
Heat stress significantly reduces feed intake, therefore directly impacting growth performance of pigs and profitability. Evidence suggests insulin action is a key component of heat stress response. Chromium improves insulin function and results in efficient clearance of glucose from the bloodstream. Increased glucose uptake may improve thermal tolerance in heat stressed animals.
