Fish oil from GM plants

The work, published online today by Nature in Scientific Reports, comes from a collaboration between Rothamsted Research and the University of North Texas. The researchers found that genetically modified Camelina sativa, one of Europe’s oldest oilseed crops, is able to produce omega-3 long-chain polyunsaturated fatty acids (LC-PUFAs) EPA and DHA.This was made possible by engineering the oilseed crop with genes from marine microbes. EPA and DHA are normally produced in abundance only by marine microbes. Growing demand for these fatty acids, especially from the aquaculture sector, has so pressurised supplies that farmed fish now contain less of these nutrients than 10 years ago. EPA and DHA are important in countering the relentless global rise in cardiovascular disease and metabolic disorders. In camelina, they also come without the contamination associated with some ocean-sourced fish oils, such as that from heavy metals, dioxins and polychlorinated biphenyls (PCBs). The researchers found that the transgenic plants can also actually grow in the field. “Demonstrating that our GM camelina works in the field under real world conditions confirms the promise of our approach,” says Johnathan Napier, Leader of the Camelina Programme at Rothamsted, which led the research. “Having a viable land-based source of omega-3 fish oils can really address the ever-increasing demand for these healthy fatty acids. Furthermore, our new and unexpected insights into fatty acid accumulation across the seed points towards further opportunities to optimise this,” says Napier. “I am convinced that transgenic plants such as ours can help reduce the pressure on oceanic sources of fish oils, and this study brings that one step closer to reality.”

High-carotenoid maize instead of pigments

High-carotenoid maize can be a suitable alternative to adding pigments to the feed. This is also cheaper because maize is already part of the diet, a group of Spanish researchers concluded. Skin colour is the first quality attribute of poultry meat that is evaluated by consumers.A golden skin colour is preferred by consumers, especially in North America and the Asia-Pacific markets, because this is associated with a normal state of health. Skin pigmentation is affected by genotype, the quantity and dietary source of pigments, and the health of the birds, among other factors. However, chickens, like most other animals, must obtain carotenoids from their diet because they cannot synthesize them naturally. Therefore, synthetic or natural carotenoids are therefore routinely added to feed formulations. Effect of high-carotenoid maize But pigments are expensive and hence increase the production costs. Researchers in Spain therefore wanted to study if certain crops, already used routinely in feed formulations, offer an alternative cost-effective strategy to replace colour additives if they are biofortified with sufficient levels of carotenoids. The research team tested the hypothesis that high-carotenoid (HC) maize, which was genetically engineered to accumulate high levels of β‐carotene, lutein and zeaxanthin in the endosperm, can replace carotenoid additives in poultry feed by performing two feeding trials using diets incorporating different maize lines with diverse carotenoid compositions: control (wild-type M37W, the parental line), HC, and standard yellow commercial maize supplemented with colour additives (marigold flowers and red paprika extracts). A cost-effective alternative The effects of dietary treatments on growth performance, health parameters, colour evolution and carotenoid distribution were determined. It was found that high-carotenoid maize had no adverse effects on poultry, and the birds fed on the HC diet developed similar pigmentation to those fed on the commercial diet supplemented with colour additives, although the latter had greater yellowness values due to the high levels of lutein in the feed. The researchers conclude that HC maize is a suitable cost-effective alternative to colour additives in the poultry production industry.

Evonik starts marketing GutCare® PY1 in India and Bangladesh

Evonik will now offer the probiotic GutCare® PY1 in India and Bangladesh following the launches in the United States and China earlier this year. GutCare® PY1 has a positive effect on the healthy balance of bacteria populations in the chicken gut which has been scientifically proven by numerous studies (in vitro and in vivo). GutCare® PY1 contains the spores of the strain Bacillus subtilis DSM 32315. “With our broad portfolio of amino acids and probiotics, we are able to fully support our customers on the road to sustainable animal nutrition targeting reduced use of antibiotics ", says Dr. Emmanuel Auer, Head of the Animal Nutrition business line at Evonik. A healthy gut microbiome reduces the risk of inflammatory diseases that can lead to high costs in livestock production. Commonly caused by bacteria such as Clostridium perfringens, diseases are responsible for several billion US dollars of damage to the livestock industry annually. Evonik had introduced GutCare® PY1 to the US-market in January and to the Chinese market in April this year. By the end of 2018, the company wants to be present in every Asian country with at least one probiotic. For Evonik, GutCare® PY1 is the first probiotic from the company’s own development. Since the acquisition of the probiotic business of the Spanish company NOREL S.A. in 2016, Evonik offers two probiotics: Ecobiol® (Bacillus amyloliquefaciens CECT 5940) and Fecinor® (Enterococcus faecium CECT 4515). In addition to product development, Evonik is also focusing on deciphering the mechanisms of the chicken gut. Our new simulation model will help to describe the interactions between nutrition, the immune system and the intestinal microbiotia in vitro. Based on these findings, a second step will be the development of new probiotics and feed additives that can help improve the chickens' sustainable growth. Evonik has more than 60 years of experience in the production of essential amino acids for animal nutrition. Evonik supports customers in more than 100 countries to produce healthy and affordable food for the growing world population, while conserving natural resources and reducing the ecological footprint.

BASF launches new vitamin A formulations for animal nutrition around the globe

Ludwigshafen, Germany – July 18, 2017. BASF Animal Nutrition globally launches Lutavit® A NXT, a new vitamin A product line in which ethoxyquin (EQ) is replaced by butylhydroxytoluene (BHT) as stabilizer. Lutavit® A NXT delivers long shelf-life, superior bioavailability and outstanding stability in premix and feed.These vitamin A formulations already now meet the latest Regulation (EC) No 2017/962, which requires to successively withdraw EQ as a feed additive. “Our customers’ needs drove these innovative vitamin A formulations. The result is a unique technology, which is patent protected,” said Christopher Rieker, Vice President BASF Animal Nutrition. “Extensive trials have shown that Lutavit® A NXT delivers superior product performance, and that’s what our customers around the globe rightly expect from us.” Just like the planned investment in a new world-scale vitamin A plant in Ludwigshafen, Lutavit® A NXT underpins BASF’s commitment to sustaining long-term supply reliability and to meeting the globally growing demand for vitamins. As one of the first vitamin producers in the market, BASF has more than 60 years of experience in the development and production of vitamins. Today, BASF is a worldwide leading producer of vitamin A for the animal nutrition industry.
