Gastro grub on the menu for Imperial explorers - Benin

Gastro grub on the menu for Imperial explorers - Benin | Elevage non-conventionnel et mini-élevage | Scoop.it

A team led by Imperial students return from Benin, where they have been sampling the local bug life.

 

Eating cricket kebabs, collecting bugs with local villagers, and extending our knowledge of insect eating practices in Benin were all on the menu for a two-month expedition led by two Imperial students before Christmas.

Jacques Mignon's insight:
It was great to learn more not only about insects and how they fit into the Wama people’s lifestyles and traditions, but also about their environment and their culture in a wider sense. Eating insects after collecting them was also quite fun!

Jacques Mignon's insight:

Part abstract:

"Pomacea lineata is a fresh water shellfish that is utilized as food, medicinal portions, or licking remedies. The objective of this study was to evaluate the nutritional and microbiological aspects of P. lineata and spawning. The samples were collected in the Jaguaribe River (Paraíba, Brazil) during the rainy and dry seasons. The biochemical composition, mineral composition, total mesophilic bacteria (TMB), total coliforms (TC), fecal coliforms (FC), Salmonella sp., Staphylococcus aureus, and Vibrio presence were determined. "

...

"Since P. lineata substances may be useful in the treatment of respiratory and gastrointestinal diseases without presenting toxic or cytotoxic effects already described in the literature, it may be considered as a potential functional food."

Jacques Mignon's insight:

Extrait du résumé :

"La reproduction de l’escargot L. flammea est fortement influencée par les teneurs en calcium des aliments qu’il consomme. Les régimes concentrés réduisent la durée du cycle sexuel, en ce sens que la maturité sexuelle qui est tardive (7 mois) avec les aliments végétaux (R1 et R2) a été rendue précoce (5 mois) avec ces aliments (R4 et R5). La teneur en calcium alimentaire influence le nombre total de pontes, la durée d’incubation et le taux d’éclosion des œufs, alors qu’elle n’a pas d’effet sur le poids et les dimensions de l’œuf. Le taux optimal de calcium induisant une meilleure reproduction varie de 12,02 % à 16,01 %. En outre, les animaux qui ont été nourris à ces régimes ont eu une relative longévité, un nombre élevé de pontes, une durée d’incubation réduite et un taux élevé d’éclosion des œufs, contrairement aux régimes à base de fourrages verts qui donnent des résultats peu prometteurs."

Jacques Mignon's insight:

Résumé:

"Nombreux sont ceux qui ont adopté le point de vue selon lequel la commercialisation est la solution à l'insécurité alimentaire en Afrique rurale. Les conceptions de projet ont cherché à établir des coopératives agricoles et à encourager les agriculteurs désireux de vendre leurs produits. Mais les problèmes révélés dans les années 1950 sont encore très répandus. Dans le cadre d'une contre-perspective, certains ont soutenu la pertinence de l'agriculture de subsistance et à faibles intrants. Cet article examine trois projets d'ONG en Afrique australe et dans le sud-est de l'Afrique, qui accordent la priorité à la sécurité alimentaire à travers la subsistance des ménages, à l'aide de technologies à faibles intrants, tout en encourageant la production d'un excédent à vendre. Nous examinons les points communs entre ces projets et les raisons pour lesquelles leurs stratégies se révèlent efficaces."

Bushmeat survey an indicator of wildlife disappearance in Soubre Region, Côte d’Ivoire

Jacques Mignon's insight:

Abstract:

"

The Soubre region was known to be a biodiversity hotspot as located in the Upper Guinean forest. However few decades ago, this zone faces human pressure. We conducted bushmeat and foot surveys to assess the wild animal species that have escaped from the human pressure.

Our results shown that just few mammal species involved in the game are sold in the local restaurants. The species frequently sold were: Tragelaphus scriptus, Philantomba maxwellii, Thryonomys swinderianus Artherurus africanus and Cricetomys emini. In addition, our foot survey in the field allowed to confirm the presence of few mammals species. Indeed, we found the evidence of presence of only eight species (Tragelaphus scriptus, Artherurus africanus, Xerus erythropus, Philantomba maxwellii, Dendrohyrax arboreus, Crossarchus obscures, Thryonomys swinderianus and Hippopotamus amphibious). Thryonomys swinderianus and Tragelaphus scriptus had the higher encountered rate respectively 0.76 and 0.53, followed by Xerus erythropus, Artherurus africanus and Crossarchus obscures respectively 0.46 for the two formers and 0.30 for the latest. The weakest encountered rate was found with Philantomba maxwellii and Hippopotamus amphibious respectively 0.15 and 0.07. In sum, the wildlife population is declining due to hunting pressure and deforestation."

Sustainable replacement of South American soybean meal by European protein proves difficult - Wageningen UR (2014)

Sustainable replacement of South American soybean meal by European protein proves difficult - Wageningen UR (2014) | Elevage non-conventionnel et mini-élevage | Scoop.it

Replacement of soybean meal of South-American origin in a starter pig diet by European protein sources currently in most cases does not decrease the Carbon Footprint (CFP). Innovations are required to reduce the CFP of European proteins. This is concluded by a sustainability analysis performed by Wageningen UR... in cooperation with ... a Dutch NGO... the Dutch feed industry... and the Dutch Ministry of Economic Affairs.

 

Imported soybean meal from South-America currently is one of the most important protein sources in animal feed. There is an increasing demand for protein sources of European origin. The sustainability of the alternative protein sources, in comparison to the current situation based on imported soybean meal, is an important question for the feed industry. To investigate this, a study was performed to determine the sustainability of a number of European protein sources... 

 

For this study, the following ingredients are selected: soybean meal cultivated in The Netherlands and in Ukraine, sunflowerseed meal, poultry meat meal, DDGS (Distillers Dried Grains with Solubles), meal worms, algae protein, and single cell proteins. Based on data... the nutritional value and CFP of the ingredients is determined. The ingredients are involved in the feed optimization of a starter pig diet, thereby maintaining the nutritional values of the diet. Subsequently, the CFP of the starter diet is calculated, with and without the contribution of “land use and land use change” (Luluc).

 

The CFP of the starter diet containing South-American soybean meal is considered as reference value. The different scenarios were calculated according to the principles of the called ‘attributional LCA’ approach, which does not take the displacement effects into account. Additional, three scenarios are worked out according to the principles of a ‘consequential LCA’, in which displacement effects are considered.

 

The most important conclusions... Only two options... are able to replace soybean meal from South-American origin... without increasing the CFP of the diet... all other scenarios result in an increase of the CFP of the diet.

 

Innovations are required to reduce the CFP of European proteins... aquatic proteins, e.g. seaweed and algae, lay a limited claim on consisting farmland, and therefore, the development of these cultivations can contribute to the increase of the European protein production. Insects are able to convert low value protein into higher value protein, and therefore insects can have a valuable contribution to the European protein supply. The conversion of low valuable proteins to insect protein, however, means an additional link in the food chain. This means the occurrence of inevitable losses, thereby increasing the CFP.

 

For further reducing the carbon footprint of EU protein sources, it is required that these crops will be produced more efficiently. Therefore, more attention should be given to breeding and improving of management conditions, resulting in a higher yield per hectare. The development of more efficient drying techniques is required, resulting in reduction of the carbon footprint of products that originates from wet processes (e.g. DDGS and aquatic proteins).

The uncovered volumes of bushmeat commercialize in the Amazonian trifrontier between Colombia, Peru & Brazil

Jacques Mignon's insight:

Conclusions:
"Our results show that bushmeat trade in Amazonian towns is not negligeable as compared to what is observed in Central African contexts, and that bushmeat trade in the Amazon is instead alarmingly uncovered by scientific research. The
existing but clandestine market observed calls for exploring the conditions in which it would be possible to legalize a local scale trade for resilient species so as to maintain the cultural, economic and social services provided by wildlife, while enforcing the trade of more vulnerable and protected ones."
