A Dutch feed company is the world’s first to put a feed product on the market with insect oil. The weaner feed with the insect ingredient has a lot of potential to reduce bacteria, prevent diarrhoea and improve feed intake; the key components to have a smooth transition from piglet to grower.
Abstract In order to expand with validated scientific data the limited knowledge regarding the potential application of insects as innovative feed ingredients for poultry, the present study tested a partial substitution of soya bean meal and soya bean oil with defatted black soldier fly (Hermetia illucens) larvae meal (H) in the diet for growing broiler quails (Coturnix coturnix japonica) on growth performance, mortality, nutrients apparent digestibility, microbiological composition of excreta, feed choice, carcass and meat traits. With this purpose, a total of 450 10-day-old birds were allocated to 15 cages (30 birds/cage) and received three dietary treatments: a Control diet (C) and two diets (H1 and H2) corresponding to 10% and 15% H inclusion levels, respectively (H substituted 28.4% soya bean oil and 16.1% soya bean meal for H1, and 100% soya bean oil and 24.8% soya bean meal for H2, respectively). At 28 days of age, quails were slaughtered, carcasses were weighed, breast muscles were then excised from 50 quails/treatment, weighed, and ultimate pH (pHu) and L*, a*, b* colour values were measured. Breast muscles were then cooked to assess cooking loss and meat toughness.
The Netherlands-based feed manufacturer, Coppens Animal Nutrition, has taken delivery of a batch of insect lipids produced by insect breeder, Protix. The supply deal had been flagged up several months previously.
The use of insect oil in the food and feed sector is completely new, said Dutch producer Protix.
Coppens is the first company to supplement pig and poultry feed using insect lipids, it added.
“Due to our agreement with Coppens we cannot communicate the exact amount of oil we delivered. However, it is a substantial amount, which we can supply on a regular basis,” said Stijn Vercauteren, a communications spokesperson for Protix, which breeds larvae of the Black Soldier Fly at its facility in Dongen.
Recently, there has been multi-agency promotion of entomophagy as an environmentally-friendly source of food for the ever increasing human population especially in the developing countries. However, food quality and safety concerns must first be addressed in this context. We addressed these concerns in the present study using the edible stink bug Encosternum delegorguei , which is widely consumed in southern Africa. We analysed for mycotoxins, and health beneficials including antioxidants, amino acids and essential fatty acids using liquid chromatography coupled to quadrupole time of flight mass spectrometry (LC-Qtof-MS) and coupled gas chromatography (GC)-MS. We also performed proximate analysis to determine nutritional components. We identified the human carcinogen mycotoxin (aflatoxin B 1 ) at low levels in edible stink bugs that were stored in traditonally woven wooden dung smeared baskets and gunny bags previously used to store cereals. However, it was absent in insects stored in clean zip lock bags. On the other hand, we identified 10 fatty acids, of which 7 are considered essential fatty acids for human nutrition and health; 4 flavonoids and 12 amino acids of which two are considered the most limiting amino acids in cereal based diets. The edible stink bug also contained high crude protein and fats but was a poor source of minerals, except for phosphorus which was found in relatively high levels. Our results show that the edible stink bug is a nutrient- and antioxidant-rich source of food and health benefits for human consumption. As such, use of better handling and storage methods can help eliminate contamination of the edible stink bug with the carcinogen aflatoxin and ensure its safety as human food.
Protein sources other than soybean for the diets of poultry are needed for agricultural systems in temperate regions to help avoid some negative social and ecological impacts of large-scale soybean imports from overseas. The aim of the present study was to test the suitability of alternative protein sources in diets for slow-growing organic broiler chicken. Four experimental broiler diets were tested against a commercial feed for organic broiler chicken fattening (control), containing 255 g kg1 of soybean cake was replaced with alternative feeds. The diet contained 78 g kg1 alfalfa (Medicago sativa) meal. Diet contained 78 g kg1 pea (Pisum sativum) groats. Diet contained 78 g kg1 pea groats. Diet contained 78 g kg1 alfalfa meal. Both diets containing Hermetia meal had the same amount of crude protein (CP) concentration as the control, while CP concentration was lower in diet AlfPea (by 2.7%) and in diet PeaAlf (by 3.5%) compared with the control. Over the course of the experiment, 15 broilers each (slow-growing Hubbard S757) were fattened with one of the five diets ad libitum from days 7 to 82. Additionally, all broilers received water and wheat grains (Triticum aestivum) ad libitum. Feed intake was measured by group. Daily gains, live weights, carcass weights and meat quality were analyzed individually. Compared with the control, feed intake, daily weight gain, carcass weights and feed efficiency were equivalent for all experimental diets. Regarding quality parameters, only cooking loss was increased with the HermPea diet compared with the control. The results indicate that the alternative feeds tested could replace part of the soybean products in broiler diets while achieving equivalent feed efficiency and product quality.
Three quarters of EU-wide consumers polled would be “comfortable” eating livestock fed on insect protein, says the organization behind the survey - the €3m EU funds backed insect to feed research initiative, PROteINSECT.
The long awaited EFSA opinion on the safety of using insects in animal feed and food is out. But the scope seems wide. So the question arises: does this opinion really speed up the approval of insect meal for use in livestock feed?
Dutch poultry farmers Léon and Wilco Jansen are running their second test with feeding live fly larvae to a small group of layers. Gaining experience with this alternative to soya is the main objective. Looking for and finding a separate niche sales channel for the eggs is a beautiful and financially attractive bonus.
Insect oil is a possible new source of the healthy omega-3 fatty acid. Insects make fatty acids by nature and can live on organic waste. Wageningen University examines which insects can best be used for oil and what their optimal diet should be.
The use of insect meal in animal diets is promising. But what is the nutritional value of this protein and can it serve as a good replacement for fish meal in aquafeed? We have listed some of the current knowledge in this article.
Alternative protein sources for poultry diets are necessary in order to reduce farmers’ dependence on traditional sources of protein. Supply, availability and nutritional value are some of the necessary criteria in the search for suitable alternatives.
EFSA has recommended further research to better assess the microbiological and chemical risks arising from the use of insects as food and feed, given the “uncertainties” and knowledge gaps identified in its long awaited safety assessment by released today.
The European Food Safety Authority (EFSA) has said insect pathogens potentially harmful to humans are most likely to come from rearing and processing not intrinsically associated with the insect itself – but huge gaps in data remain.
