Zinc oxide (ZnO) supplied at pharmacological dosage in diets of piglets reduces post-weaning diarrhea and improves growth performance. However, it may cause environmental accumulation and induce bacterial resistance. The effects on gut microbiota and integrity in weaned piglets of conventional ZnO at nutritional and pharmacological dosage (110 and 2,400 mg/kg Zn, respectively) were compared to HiZox®, a potentiated form of zinc oxide, at 110 and 220 mg/kg Zn. Transepithelial electrical resistance of distal small intestinal mucosa was higher for pigs fed HiZox® as compared with groups fed 110 mg/kg Zn of conventional ZnO, in line with a trend for higher gene expression of claudin‐1 and zona occludens‐1.

Zinc dose and source can affect intestinal integrity

HiZox® at 110 and 220 mg/kg Zn increased intestinal alkaline phosphatase gene transcript as compared to conventional ZnO at 110 mg/kg Zn, whereas HiZox®, at 110 mg/kg Zn exhibited higher Zn concentrations in mucosa as compared to conventional ZnO at 110 mg/kg Zn. In conclusion, the alternative ZnO reduced digesta Enterobacteriaceae numbers and improved gut integrity, albeit similar or better, depending on the dosage, to the effects of pharmacological dosage of conventional ZnO.

In 2016, 65.8 billion chickens were slaughtered in the world.

Slaughtered animals in the world

Changing patterns of human resource use and food consumption have profoundly impacted the Earth’s biosphere. Until now, no individual taxa have been suggested as distinct and characteristic new morphospecies representing this change. Domestic broiler chicken is one such potential marker.

Human-directed changes in breeding, diet and farming practices demonstrate at least a doubling in body size from the late medieval period to the present in domesticated chickens, and an up to fivefold increase in body mass since the mid-twentieth century.

Moreover, the skeletal morphology, pathology, bone geochemistry and genetics of modern broilers are demonstrably different to those of their ancestors. Physical and numerical changes to chickens in the second half of the twentieth century, i.e. during the putative Anthropocene Epoch, have been the most dramatic, with large increases in individual bird growth rate and population sizes.

Broiler chickens, now unable to survive without human intervention, have a combined mass exceeding that of all other birds on Earth; this novel morphotype symbolizes the unprecedented human reconfiguration of the Earth’s biosphere.

1 euro coin

Historically, almost all coins were made of copper. Nowadays, 1€ coin is mixed with other metals: Inner is 75% copper and 25% nickel, outer is 75% copper, 20% zinc and 5% nickel.

Why copper?

It has an excellent resistance to corrosion and an average lifetime of 30 years. Moreover, its excellent malleability allows to have clear images and distinct edging on coins.

Finally, copper has a very low risk of inducing allergic reactions and it is highly sustainable as it is totally recyclable

In 2015, EU’s agricultural sector accounted for 10 % of the EU’s total emissions of green house gases (GHG).

Contribution of agriculture to total GHG emissions

The three GHGs are carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4). The first three contributors to GHG emissions in 2017 were the following economic activities : supply of electricity, gas, steam and air conditioning (21%), households (18%), manufacturing (16%).

The European Food Safety Authority (EFSA) had recommended, in their Opinion published in July 2016, some newly proposed maximum contents for copper in animal feeds. With a suggested drastic reduction of supplemented copper in piglet diets, they acknowledged that performance of weaned piglets would be impacted. This explained why it took exactly two years to the European Commission before they published Regulation (EU) 2018/1039, finding a compromise with a stepwise approach on progressive decrease of dietary copper in the nursery phase of growing pigs. Deadline to implement this change was in February for premixes, and will be in August for feeds.

CoRouge®, a source of feed grade copper, is authorized in the European Union since December 2016. It has been selected by leading feed manufacturers as a nutritional solution to accompany this regulatory change.

Ask your Animine representative how CoRouge® can contribute to maximise your piglet feed performance.
