AP News : Worms: A Zimbabwe snack, from tree to dinner table | Elevage non-conventionnel et mini-élevage | Scoop.it

At the local market, mopane worms are popular with residents who buy a cup or two of them and eat them immediately. The market is abuzz with activity, with most stalls strategically displaying the delicacy so people cannot miss them. Vendors offer free samples.

Jacques Mignon's insight:

Mignon, J. (2002). "A l’heure où l’on parle tant du respect de la biodiversité, il ne faut pas oublier les menaces qu’une pratique intensive de captures à des fins alimentaires (pour l’homme ou les animaux d’élevage) fait peser sur de nombreuses espèces d’insectes. Il faut que les populations en plein développement démographique prennent conscience du fragile équilibre de la nature et qu’elles développent des moyens permettant de remplacer la récolte in natura par le petit élevage. Divers projets locaux sont actuellement développés en Afrique afin non seulement de protéger certaines espèces mais surtout pour maintenir et renforcer l’apport protéinique à certaines populations."

Ana C. Day's curator insight, January 29, 2013 11:57 PM

"

HIGH PROTEIN

The mopane worm is a healthful and cheap source of nutrition.

A Zimbabwean nutritionist, Marlon Chidemo, says the worms are high in healthy nutrients and contain three times the amount of protein as beef. He says eating worms is less taxing on the environment than consuming beef because it takes far fewer leaves to produce worms than it does feed to produce the same amount of beef.

WORMY BUSINESS

Dried mopane worms have become a multimillion-dollar industry, even exported to countries like South Africa and Botswana. They can be found in African restaurants in Paris."

Abstract

"Contract broiler farming is one the system used to increase poultry production in Malaysia. Broiler contract farmers (BCF) participate in this system for having some benefits. This paper has evaluated economic performance of the BCFs in Perak. An economic evaluation of 60 BCFs was conducted in Perak to determine the performance of the system using economic performance analysis. Panel regression model was used in the analysis. This model involves price per bird (PRM) as dependent variable and size of farm (SOF), feed conversion rate (FCR), average body weight(ABW), average marketing age (AMA), mortality rate (MOR), and rearing housing system (DU). The results show that all variables, except SOF, are significantly influence the performance of BCF at five percent level of significance."

Using Communication to Improve Grasscutter (Thryonomys Swinderianus) Reproductive Behaviour in Cote D’Ivoire

Jacques Mignon's insight:

Stress is a limiting factor in the production of grasscutters. Communication experiments were therefore conducted to reduce
or eliminate the psychosocial stress and panic instinct with grasscutters.

...

These results suggest the technique of communication beyond words as a solution to psychosocial stress of farmed grasscutters.

Early View

Jacques Mignon's insight:
Abstract

A study was conducted to determine the protein requirement of the white-lipped peccary (Tayassu pecari) performing a nitrogen (N) balance digestion trial. In a 4 × 4 Latin square design, four adult captive male peccaries were fed four isoenergetic diets containing four different levels of N (13.3, 19.2, 28.7, and 37.1 g N/kg dry matter). After 15 days of adaptation, the total collection of feces and urine was carried out for five consecutive days. By regression analysis between N intake and N in feces and urine, the metabolic fecal nitrogen (MFN = 3.1 g/kg of dry matter intake) and daily endogenous urinary N (EUN = 91.0 mg/kg0.75) were determined. Likewise, by regression analyses between consumption of nitrogen and the nitrogen balance [NBN consumed–(fecal N + Urine N)] we estimated the daily requirement of 336.5 mgN/kg0.75. Therefore, if food intake is unrestricted, white-lipped peccaries require a minimum content in their diet of about 4.5% crude protein as percentage of dry diet. These values are similar to those found in frugivorous wild ruminants, which reinforces the proposition that peccaries have a digestive physiology nearer to that of ruminants than of domestic pigs. Furthermore, the low nutritional maintenance requirements for white-lipped peccary may explain how this species thrive in the Neo-tropical region eating predominantly palm-fruits that normally have low crude protein contents.

Non-genetic factors affecting fitness traits in the grasscutter (Thryonomys swinderianus)

Non-genetic factors affecting fitness traits in the grasscutter (Thryonomys swinderianus) | Elevage non-conventionnel et mini-élevage | Scoop.it
This study was conducted at the grasscutter section of the University of Education, Winneba, Ghana, to estimate non-genetic effects on reproductive and survival traits. Data consisted of records on 136 does from 2006 to 2010. Litter size at weaning, litter weight and lactation weight loss all increased (P < 0.01) with increasing litter size at birth. Litter weight and lactation weight loss increased (P < 0.05) at weaning, whilst days of joining decreased (P < 0.01), with increasing years. Minor rainy season was found to be the most suitable mating season. Dams that kidded in dry season took fewer (P < 0.05) days to conceive than in other seasons. Nursing dams lost more (P < 0.05) weight in dry and minor rainy seasons than in major rainy season. Increasing parity led to decreasing (P < 0.05) pre-weaning survival of offspring. Post-weaning survival of offspring decreased (P < 0.01) with increasing years. Kids conceived in the minor rainy and dry seasons had significantly higher (P < 0.05) post-weaning survival rates than those conceived in the major rainy season. Post-weaning survival rates of kids born in the minor rainy season were lower (P < 0.05) than those born in other seasons. It was concluded that non-genetic factors influenced fitness traits and must therefore be considered when designing grasscutter breeding programmes.

From taboo to commodity: history and current situation of cavy culture in the Democratic Republic of the Congo

Livestock Research for Rural Development 26 (8) 2014

B L Maass, T K Metre, F Tsongo, A B Mugisho, F M Kampemba, R B B Ayagirwe, P C Azine, J Bindelleand W L Chiuri 

 

Jacques Mignon's insight:

Part of the conclusions :

"Cavy culture contributes to the wellbeing of hundreds of thousands of mostly poor, rural and urban households in DRC who see the animal as an important asset. The rapid growth in their contribution – a contribution that is clearly being adopted widely – suggests that greater R4D investment is necessary if production is to reach the potential that is common place in some South American countries. There is firstly a need to get more accurate information on cavies and their roles across DRC; and to do that, cavies need to be included in livestock census. They have a particular stake in the empowerment of women and the youth as a non-monetary service and an indirect benefit by assisting to meet some of the household nutrition requirements and contribute to the educational costs of many children (Maass et al 2012, 2013). As such they may serve as the first rung on the livestock ladder that can help to acquire certain levels of wealth (Maass et al 2013). It is likely that cavy culture will continue its expansion in DRC and that growth will be supported by a project on ‘Harnessing husbandry of domestic cavy for alternative and rapid access to food and income in Cameroon and the eastern Democratic Republic of the Congo’. Progress will expedite by accessing knowledge from South America, where improving cavy culture has received attention over decades (Chauca de Zaldívar 2000). Knowledge exchange between project partners from Cameroon and DRC will additionally help to advance cavy culture in the region."

Neosomes of tungid fleas on wild and domestic animals

Neosomes of tungid fleas on wild and domestic animals | Elevage non-conventionnel et mini-élevage | Scoop.it

"Although its effects on humans and domestic animals are well described in the literature, little is known about the impact of tungiasis on wild animals."

Jacques Mignon's insight:
Pedro Marcos Linardi,Daniel Moreira de Avelar

 

Abstract :

"

Tunga is the most specialized genus among the Siphonaptera because adult females penetrate into the skin of their hosts and, after mating and fertilization, undergo hypertrophy, forming an enlarged structure known as the neosome. In humans and other warm-blooded animals, neosomes cause tungiasis, which arises due to the action of opportunistic agents. Although its effects on humans and domestic animals are well described in the literature, little is known about the impact of tungiasis on wild animals. This review focuses on the morphology, taxonomy, geographical distribution, hosts, prevalence, sites of attachment, and impact of tungid neosomes on wild and domestic animals. Because neosomes are the most characteristic form of the genus Tunga and also the form most frequently found in hosts, they are here differentiated and illustrated to aid in the identification of the 13 currently known species. Perspectives for future studies regarding the possibility of discovering other sand flea species, adaptation to new hosts, and the transfer of tungids between hosts in natural and modified habitats are also presented."

B L Maass, T K Metre, F Tsongo, A B Mugisho, F M Kampemba, R B B Ayagirwe, P C Azine, J Bindelle and W L Chiuri

Jacques Mignon's insight:

Part abstract:

"For the first time, the status of cavy culture in the Democratic Republic of the Congo (DRC) is reviewed with emphasis on Sud-Kivu province. Cavy culture, as discussed in this paper, is the raising, production and utilization of the domestic cavy (i.e., Guinea pig, Cavia porcellus) for consumption. Many sources were used in the review, but published scientific research literature is extremely scarce. Nevertheless, it can be estimated that more than 2 million cavies are kept in DRC, contributing significantly to nutrition security, especially animal protein, and income generation of some hundreds of thousands of poor rural and urban households. The largest cavy populations are in the Kivu provinces, which is probably partly due to the inclusion of cavies in ‘rehabilitation kits’ of humanitarian NGOs and in the agricultural portfolio of development agencies who seek to address the challenges of widespread hunger and malnutrition in the area."

Relative economic value estimates of grasscutter production traits

Relative economic value estimates of grasscutter production traits | Elevage non-conventionnel et mini-élevage | Scoop.it

The study was conducted to estimate relative economic values (REVs) of survival, body weight, growth rate, reproduction, docility and food intake. Data were obtained from records of grasscutters (Thryonomys swinderianus) kept at the grasscutter section of the Department of Animal Science Education, University of Education, Winneba, Ghana. Average values of production inputs and outputs parameters were computed from records of 502 kids born between 2006 and 2010.

...

It was concluded that post-weaning growth rate, litter size at weaning and docility should be selected to be included in the breeding objective of grasscutter breeding programmes in Ghana.

Jacques Mignon's insight:
Part Abstract

To determine the impact of farming over vicuña population in Peru, serum samples were collected from 207 vicuñas (126 captive vicuñas and 81 free-ranging vicuñas) and 614 domestic South American camelids (571 alpacas and 43 llamas), in ten Andean communities at the Salinas y Aguada Blanca reserve, province of Arequipa, southern Peru.

...

This is the first study where health status of free-ranging and captive vicuñas has been compared. Results indicate minimal to nil presence of FMD, BVD, BHV-1, brucellosis, BT, paratuberculosis, and neosporosis allied to health disorders in our sample. The detection of seropositive animals against Leptospira, however, unveils the likely significance of leptospirosis in wild and domestic South American camelids, the impact of mixed husbandry over vicuña population and the risk to human health.

Journal of Applied and Natural Science 6 (1): 220-225 (2014)

Jacques Mignon's insight:

Abstract : The study was carried out to develop retail cuts, evaluate the effect of the method of pelage (removal/ scalding) on the yield and organoleptic quality of smoked grasscutter (Tryonomys swinderianus). Sixteen grass cutters were purchased from Abico bush meat market in Benin City, Nigeria. The pelages were removed by water and fire scalding. Some were brined in 15% salt solution for 3 hrs while others were not. The carcasses were cut into seven retail cuts. All samples were smoke-dried for 6 hrs. Sensory evaluation was done by a 12-man panel using a 5-point hedonic scale. The results showed that there were significant differences (P<0.05) in the yield of fresh salted and non-salted grass cutter samples. There was also significant difference (P<0.05) in the smoked yield of salted smoked grasscutter with WSS giving the highest yield of 1.03 kg. The method of pelage removal did not have any significant effect (P>0.05) but there was significant effects in the smoked yields. Sensory evaluation showed significant differences (P<0.05) in the colour, tenderness, juiciness, flavor and overall acceptability. Salted samples had the highest scores all organoleptic properties. It was recommended that further studies be carried out to evaluate the effects of salting and smoking on economic and sensory parameters of other sources of bush meat in Nigeria.

Protein production: planet, profit, plus people?

Harry Aiking

First published May 28, 2014

doi: 10.3945/ajcn.113.071209

Am J Clin Nutr July 2014 ajcn.071209

Jacques Mignon's insight:

Part abstract :

"Food sustainability and food security are increasingly in the spotlight and increasingly intertwined. According to some projections we will need to nearly double food production in the next 4 decades. This article argues that protein production and consumption are pivotal to sustainability, because anthropogenic contributions to the nitrogen cycle are 100–200% compared with a contribution of 1–2% to the carbon cycle by mineral fuel combustion, with biodiversity as the main casualty. Because 1 kg animal protein requires ∼6 kg plant protein, its large-scale production by means of factory farming is a major driver of biodiversity loss, climate change, and freshwater depletion. Furthermore, intensive livestock production is associated with antibiotics resistance and increasing incidence of emerging diseases. Therefore, a “reversed” diet transition back to less animal protein could make a difference. Some European countries, such as the United Kingdom, Sweden, and The Netherlands, have published integrated policy reports addressing food security, sustainability, and health combined. The food industry is focusing on food safety and increasingly on sustainability. An important issue is consumer communication, because consumer “framing” is radically different from that of governmental and industrial policy makers."
