Content: World’s Largest Insect Farm to Open in France

Once fully operational, the massive vertical farm will produce 200,000 tonnes of insect-based ingredients a year.

Ÿnsect, one of the world’s largest insect rangers, is betting big on bugs to help push the world in a more sustainable direction.

Founded in 2011, the company is fast approaching its goal of opening the world’s largest insect farm and dramatically scaling up its operations. Located about an hour north of Paris, the state-of-the-art facility will leverage automated systems and vertical farming techniques to raise mealworms (Tenebrio molitor) and enable the production of over 200,000 tonnes of insect-based ingredients per year. The site, estimated to be completed by the end of 2022, will join two other Ÿnsect facilities already operational in France and the Netherlands.

"It’s an automated warehouse, very similar to an Amazon warehouse, where instead of storing stuff, we are storing live insects," Ÿnsect CEO and co-founder Antoine Hubert told Time last year. "There is a climate-control system which is highly complex to maintain temperature and moisture from zero to 30 meters high. All operations are automated. Anything that you do on [an insect] farm is done with robots."

Feed for Fish, Fertilizer for Plants, Burgers for Humans

For the past decade, mealworms cultivated at Ÿnsect’s farms have been turned into powders and oils that have become nutritional additives to pet and farm feeds. Thanks to a ruling last year by the European Food Safety Agency (EFSA) that deemed mealworms safe for human consumption, the company has also begun selling its powders for shakes, cereal bars, pasta, and even alt-meat burgers. In addition, the shed shells of the rapidly growing mealworms are collected and sold as beneficial organic fertilizers to farmers.

According to MealFlour, a project that promotes mealworm farming as a way to battle malnutrition in Guatemala, a serving of mealworm powder is 55% protein, contains all essential amino and fatty acids, and has more iron than sirloin beef. Compared to the production of milk, pork, chicken, and beef, mealworms are also more sustainable and require fewer resources and energy.

While its recent forays into human foodstuffs have garnered attention, Ÿnsect's focus presently remains on helping to feed sustainably the animals that feed the world. For instance, aquaculture, like salmon farming, is a resource-intensive operation that uses both land-based crops (soy) and massive amounts of wild-caught fish to create what's known as fishmeal. With food production projected to have to grow by more than 70% by 2050 to meet demand, the overfishing of oceans to feed aquaculture operations is not a feasible option. Studies, such as a recent trial by NOAA, have shown that supplementing or even replacing fishmeal with insect- and plant-based foods holds promise for eliminating the need for wild-caught sources. According to Hubert, there are other positives as well.

"They [salmon] were reaching the maturity stage faster and eating less so they were avoiding a large quantity of feed," he told Fast Company in 2020. "There was less mortality so the farmers get more fish eventually than before... This also explains why we have a carbon-negative balance, because we are avoiding so many quantities of inputs to feed fish to have the same quantities of fish."

Hubert added to Fast Company that Ÿnsect has contracts worth more than $100 million with fish feed producers. This past year, with the acquisition of U.S.-based mealworm producer Jord, it also began entering new markets, such as the rapidly growing U.S. backyard chicken feed market.

A Record-Breaking Vertical Farm

One look at the animated video of Ÿnsect’s new facility up above and you can see why it’s been touted as an automated marvel. Mealworms will be reared by robots in stacked tubs stretching several stories tall. Unlike other insect food alternatives such as flies or crickets, mealworms do not hop or fly, allowing the company to maximize the space available.

In an effort to make sure the creatures are ethically farmed, Hubert reached out to philosophers from the Sorbonne University to judge their welfare. As he told The Guardian, the students determined that the mealworms had "more in common with mushroom-growing and hothousing vegetables" than with livestock.

"They have no brain in the strict sense of the word," he said. "We know they have a reflex reaction and they communicate and build intelligent structures, but nobody has shown they feel anything. However, what is important is to respect them as living organisms, which we do."

In addition to the new farm in France, Ÿnsect plans to continue to scale its operations with additional facilities, including a major site in the U.S. The biggest hurdle ahead, however, says Hubert, is making insects a normal part of everyday diets.

"I believe that the big challenge is accepting insects as part of the human diet," he told Authority Magazine. "A large part of the world's population eats insects, but we must be able to prove its properties and its benefits for the environment in order to reach more and have more impact!"

What health concerns are there specifically related to additives in farmed salmon feed?

Insect meal is used as a replacement for fish meal in salmon feed, as produced by companies like Ÿnsect.

"Antibiotics are being replaced as an additive in animal feed, potentially including salmon feed, due to safety concerns and are being substituted with microbial biologics like probiotics, prebiotics, and symbiotics."

To make food for animals more useful will help the study of students and scientists PNIPU
14.04 Wednesday, August 2, 2023
Proper feeding of farm animals and birds, such as chickens, pigs, cows and others, is a very important task in the process of their cultivation.
Previously, various antibiotics were added to the feed to support the immune system, proper functioning of the gastrointestinal tract and treatment of parasites, but along with meat and other animal products, drugs could also enter the human body, which is considered unsafe.
Therefore, now microbial biologics (probiotics, prebiotics and symbiotics) are used as an alternative.
They are environmentally safe and do not cause side effects, and also have a positive effect on the microflora of the gastrointestinal tract, which allows you to maintain the health of farm animals and birds.
But the production of such drugs is not cheap, in connection with which today there is a search for a better and cheaper substitute.
Scientists of the Perm Polytechnic University have identified factors that improve the biosynthesis of the necessary enzymes, as well as created a technology that will make food for animals more useful.
The development was carried out within the framework of the program of strategic academic leadership "Priority 2030".
The article with the results of the study was published in the journal “Vestnik PNIPU.
Chemical Technology and Biotechnology. ”
To date, bran, which is a waste of grain production, is used as an additive in the feed of farm animals and birds.
To improve the digestibility of protein components, enzyme preparations are added to them, due to which the number of amino acids and peptides in the feed composition increases.
Such biologics are made on the basis of animal tissues, but their cost is very high and unprofitable for agricultural producers.
Polytechnics believe that the enzyme component can be replaced by a safe bacterium of the species Bacillus subtilis, which can be easily grown on waste grain production.
- Spore-forming bacteria of the genus Bacillus secrete special enzymes that “process ” indigestible feed from bran into easily digestible proteins and amino acids.
In the course of the work, we optimized the nutrient medium for the growth of microorganisms and the production of proteolytic enzymes.
In the initial experiments, protein was added in the form of albumin and casein.
Further, in order to optimize, we chose waste: sunflower meal (a by-product in the production of vegetable oils) and wheat bran, that is, animal protein was replaced with vegetable protein.
And as a source of nitrogen, instead of peptone and yeast extract, urea was used to reduce the cost of the nutrient medium, - says the project manager, associate professor of the Department of Chemistry and Biotechnology of PNRPU, candidate of chemical sciences Anna Portnova.
During the study, the researchers cultured a bacterium of the species Bacillus subtilis in a nutrient medium containing a set of salts that provided the need for microorganisms for magnesium, calcium, sodium and potassium ions, as well as 5% of bran.
As a carbon source, polytechnics used glucose in various concentrations.
They introduced a culture of bacteria into the nutrient media in an amount of 1%.
Next, the scientists carried out incubation in a thermostatic rocker, observing a temperature of + 370 ° C and a mixing speed of 130 revolutions per minute.
Every 24 hours, they determined the amount of amino acids formed.
- According to the results of cultivation, it can be concluded that proteolytic enzymes work well on waste added to the media.
By breaking down proteins into amino acids, they convert them into a more accessible, more easily digestible form for consumption by farm animals.
The proteolytic activity of the obtained feed additive is 0.025 units per 1 gram of bran and its cost price is lower than that of the analogue, for example, Protosubtilin.
In addition, we calculated the rates of introduction of the drug into the feed for birds.
In comparison with other additives, our is quite convenient to add to the feed mixture, - says a student of the Department of Chemistry and Biotechnology of PNRPU Elena Kravtsova.
Thanks to the data obtained during the experiment, a bioreactor with a stirrer for the culture fluid used to enrich wheat bran was designed, and a technological scheme for obtaining a feed additive based on bacteria Bacillus subtilis and bran for the purpose of saving resources in agriculture was developed.
The study of scientists of the Perm Polytechnic University will help to make the nutrition of farm animals more useful and safe.
The development will allow avoiding the preventive use of antibiotics in animal husbandry, and will also be able to solve the problems of import substitution in the field of feed additives for agriculture.

The country where feed additives are managed is Taiwan, with various management methods in place for different environments.

Title:

Content: Chen Jizhong, chairman of the Council of Agriculture, said in an interview with the DPP Network Department Podcast that "the ear does not travel out of oil", Leckdopamine is a feed additive, "just like people, we usually eat three meals, but you will eat some health food". Sorry about the overextension, the future will be more precise words.
Chen Jizhong said in an interview with the DPP Network Department Podcast “The ear does not travel out of oil ”,“ Leckdopamine is a very simple product, that is, for example, you want to make the pig grow up, and finally provide us when the pig is eaten, you have to add some additives in addition to feed him, feed is like corn, or soybean meal to mix it. We usually eat three meals, but you will eat some health food, in fact, he let his meat exchange rate, let the lean meat more than fat. "
As soon as this statement occupied all the major pages of the media yesterday, some people criticized "Since lyophilic acid is so good, why not use it?", "Now it has become a good additive, the chairman has made me so confused!", "Open up good things, Taiwan's beautiful relations!" 」
Chen Jizhong responded today that Leckdopamine is originally a feed additive for pigs and cattle. He has never said that Leckdopamine is a health food, and he regrets the excessive expansion of the outside world.
Different countries in the world have different management methods for feed additives. In Taiwan, there are already additives for feed and drugs in Taiwan, such as probiotics, vitamins, amino acids, etc., will be based on different environments to do feed management, "If the words on the broadcast are not accurate, they will be more accurate in the future."
Chen Chi-chung says that when President Tsai opened Lai-pig on August 28 last year, he communicated with all farmers, and in order to make the market for pork at home and abroad, by clearly marking that the feed should not be used as lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-lai-was.

The global feed acidifiers market grew from $2.48 billion in 2022 to $2.71 billion in 2023 at a compound annual growth rate (CAGR) of 9.0%. The Russia-Ukraine war disrupted the chances of global economic recovery from the COVID-19 pandemic, at least in the short term. The war between these two countries has led to economic sanctions on multiple countries, a surge in commodity prices, and supply chain disruptions, causing inflation across goods and services, and affecting many markets across the globe. The feed acidifiers market is expected to grow to $3.55 billion in 2027 at a CAGR of 7.0%.

The feed acidifier market consists of sales of formic acid, citric acid, propionic acid, lactic acid, essential oils.Values in this market are 'factory gate' values, that is the value of goods sold by the manufacturers or creators of the goods, whether to other entities (including downstream manufacturers, wholesalers, distributors and retailers) or directly to end customers.

The value of goods in this market includes related services sold by the creators of the goods.

The feed acidifier are used to inhibit the growth of pathogenic bacteria.Feed acidifiers are added to feeds to decrease the pH of the feed, gut, and microbial cytoplasm, preventing harmful intestinal microflora from growing.

This inhibits bacteria from competing for host nutrients, resulting in improved development and performance.

Asia-Pacific was the largest region in the feed acidifiers market in 2022.North America is expected to be the fastest-growing region in the forecast period.

The regions covered in the feed acidifier market report are Asia-Pacific, Western Europe, Eastern Europe, North America, South America, Middle East and Africa.

The main types of feed acidifiers are propionic acid, fumaric acid, lactic acid, formic acid, and others.The propionic feed acidifiers are used to reduce acidogenesis and when propionic acid is added to a glucose-containing growth medium, a random copolymer consisting of 3-hydroxybutyrate and 3-hydroxy valerate is formed.

The various forms include dry, and liquid, divided by livestock into poultry, swine, ruminants, aquaculture, pets, and others. The several compounds are blended into singles.

The rise in the demand for meat and dairy products is expected to propel the growth of the feed acidifier market going forward.Meat and dairy products refer to a healthy, balanced diet that includes protein from meat, as well as from fish and eggs.

Acidifiers promote the absorption of minerals from animal meat and dairy products by improving nutrient digestibility.For instance, in May 2020, a study by Food Choice and Consumer Preference on willingness to pay for meat alternatives suggests that animal-based meat consumption is on the rise in India, and an estimated 64-74% of the population of India consumes some form of animal-based meat occasionally.

Moreover, according to the food and agriculture organizations of the United States, by 2025, global milk output is expected to expand by 177 million tonnes, with an average annual growth rate of 1.8%. Therefore, the growing demand for meat and dairy products is driving the growth of the feed acidifier market.

Strategic partnerships are a key trend gaining popularity in the feed acidifier market.Major companies operating in the feed acidifier sector are focused on partnerships to strengthen their position in the market.

For instance, in January 2021, Azelis, a Belgium-based service provider to the food industry, partnered with Perstorp AB, a Sweden-based chemical company.Through this partnership, both companies represent themselves in Great Britain for their animal nutrition range of gut health solutions, feed hygiene solutions, acidifiers, silage additives, and total mixed ration and grain preservatives.

Furthermore, in December 2020, BELFEED, a Belgium-based feed additives company, partnered with JEFO Europe, a Poland-based non-medicated animal nutritional solution provider. Through this partnership, Jefo became an exclusive distributor in central European countries, such as Poland, Hungary, and the Czech Republic.

In May 2021, Eastman Chemical Company, a US-based chemical company, acquired 3F Feed & Food for an undisclosed amount. The combination of Eastman's chemical expertise together with 3F's R&D skills is expected to increase the product offering of new molecules that can be successfully deployed to a market. 3F Feed & Food is a Spanish firm that produces preservatives and acidifiers as well as liquids and powders for the sanitation, safety, and preservation of animal health nutraceuticals and feed.

Journalist Hsu Chien-yi / reporting from Taipei
In recent years, the unusually high temperature in summer has led to the outbreak of germs, which has caused great losses to farmers. The probiotic Lactic Acid Bacillus B4, which helps to improve fish growth and enhance their immunity, and its glucan product Lactic Acid Bacillus B4 functional yogurt was added to the feed. Farming time to reduce the risk of breeding.
The water laboratory pointed out that glucan can be used as an emulsifier and thickener flavor carrier in food processing. In terms of health care, research shows that glucan can be used as a prebiotic to increase the number of probiotics - bifidobacteria and lactic acid bacteria in the body, and regulate immunity.
As mentioned in the water test, lactic acid bacteria B4, previously screened from the gut of perch fish, is a probiotic with special enzymes. Adding cheap sucrose can promote the production of glucan by lactic acid bacteria B4, and developed functional yogurt and ice cream containing glucan with lactic acid bacteria B4.

According to the water test, the literature points out that probiotics or prebiotics such as glycans and oligosaccharides as feed additives can effectively improve the growth and immunity of fish and shrimp. The combined use of probiotics and prebiotics is usually higher than the combined effect of the two alone. Probiotics that produce pathogens can also produce glucans themselves, so the lactobacillus B4 yogurt is applied to aquaculture.
Experimental studies show that the addition of lactic acid bacteria B4 yogurt in the feed helps to improve the growth and resistance to pathogens.

In recent years, due to climate change, the unusually high temperature in summer can easily lead to the outbreak of germs, causing the death of fish and loss of farmers. Three years ago, the Kaohsiung City Animal Protection Department sought technical assistance from the water laboratory. 4 Yogurt feed for 2 months, fish feeding conditions are better than the control pond, growth is very fast, at the end of May harvest, no disease, fish average weight 570 grams, strong and healthy.
When the fish are harvested, the fisherman must wear a safety helmet to avoid being injured by the energetic Wu Kuo. The fish in the control pond eat worse than the test pond and grow more slowly. In mid-June, the fish suffered from streptococcus disease. It must be treated with drugs. The average weight is 467 grams, which is much lower than the average. Test pool.
The water laboratory further stressed that in order to understand whether the feed containing lactic acid bacteria B4 yogurt can really survive the cool summer, and the Kaohsiung Municipal Bureau of Animal Protection specially arranged the test in the summer the previous year. The results showed that although the test group and the control group of the fish containing lactic acid bacteria B4 yogurt were all suffering from streptococcal disease, the test group were milder drug. The treatment only takes 3 days to heal, and the control group is more serious, requiring more than 7 days of drug treatment.
Therefore, the addition of lactic acid bacteria B4 yogurt in broccoli feed helps to improve the growth and health of the fish, shortens the breeding time, reduces the breeding risk and slows the severity of the disease, and the cost of adding lactic acid bacteria B4 yogurt per kilogram of feed is only about 0.5 yuan.

The types of Omega 3 fatty acids found in farmed salmon are EPA and DHA.

Title:

Content: Cheaper salmon is 'as good as premium farmed products when it comes to Omega 3', study shows

  • Fish-eaters benefit from two Omega 3 fatty acids – EPA and DHA – which can boost heart health and thinking skills
  • Researchers analysed packs of farmed Scottish and Norwegian salmon from 10 UK supermarkets
  • The best provided 67% of the recommended weekly Omega 3 but the worst only offered 26%

Premium farmed salmon may be no healthier than value brands when it comes to Omega 3, a study has shown.

Fish-eaters benefit from two Omega 3 fatty acids – EPA and DHA – which can boost heart health and thinking skills.

Researchers analysed packs of farmed Scottish and Norwegian salmon from 10 UK supermarkets.

The best provided 67 per cent of the recommended weekly Omega 3 but the worst only offered 26 per cent.

Fillets from two stores did not contain significantly more Omega 3 than non-premium products.

Farmed salmon tend to be fed a mixture of fish and vegetable oils but the latter lack the fatty acids found in seafood.

Study leader Dr Matthew Sprague, from Stirling University, said: 'The amount of EPA and DHA can vary based on the cut of salmon, as well as what it was fed, but farmed salmon is still high in nutrients.'

Salmon not only contains Omega 3 but selenium and phosphorus, which are also important for health.

Andrew Opie, director of food and sustainability at the British Retail Consortium, said: 'Consumers take various factors into consideration when buying salmon, including its health benefits and the way it is produced, and they will weigh these up when choosing what to purchase in a supermarket.'

Salmon not only contains Omega 3 but selenium and phosphorus, which are also important for health

Phil Brooke, from Compassion in World Farming, said: 'Intensive fish farming is bad for fish welfare and the product only contains Omega 3 due to the wasteful consumption of feed containing fish oil.'

Wild salmon consume only fish oil, which they get from algae and smaller fish, but lose fatty acids from that fish oil, as they become leaner during the migration back from the sea to the river to spawn.

This means farmed fish, which are kept confined in cages within the sea, can contain more Omega 3 than the wild variety.

But vegetable oil is more accessible, sustainable, and also cheaper than fish oil for the expanding fish farming industry.

So more of this can be used, which substantially reduces the amount of Omega 3 in farmed salmon.
