A Critical Review of Epistemological and Methodological Issues in Cross-Cultural Research

Cross-cultural management research suffers from many shortcomings. While some of these shortcomings are related to methodology, others can be identified as epistemological problems. By recognizing that epistemological positions determine methodological approaches, this paper attempts to discuss both epistemological and methodological issues in cross-cultural research. Based on extant literature, major drawbacks are discussed and some suggestions for future research are presented

Typology of goat feeding systems in Benin

Feeding is one of the limiting factors of productivity in goat production in developing countries. That’s why this study was carried out to characterize the feeding systems used in goat farming in Benin. Accordingly, a semi-structured survey was conducted among 533 goat farmers in 6 agro-ecological zones in Benin. Data were collected on socio-demographic characteristics, breeding practices and feeding methods. A typology of goat feeding systems was developed using a factorial analysis of mixed data followed by an ascending hierarchical classification. The results of the study revealed three main types of feeding systems. These are feeding systems based on the use of: (i) natural pasture in a free-grazing system, (ii) natural pasture, crop residues and concentrates in a semi-controlled breeding system, and (iii) natural pasture, crop residues and concentrates in a controlled breeding system. The implementation of a programme to improve goat feeding and management systems will contribute significantly to increasing goat productivity. It will also contribute to food security in the rural community. Keywords: Benin, Capra hircus, feeding practices, management practice

Effets du remplacement de la farine de poisson par les termites (Macrotermes Sp.) sur l’evolution ponderale et les caracteristiques de carcasse de la volaille locale au Burkina Faso

The high cost and the accessibility of animal protein sources is a major issue in poultry farming in Burkina Faso. The present study aimed to assess the suitability of two termite species as feed for traditional chicken (Gallus domesticus) and guinea fowl (Numida meleagris), comparatively to commercial fishmeal available in this country. The study was carried out during eight weeks in Burkina Faso on ninety chickens and ninety guinea fowls, sixteen weeks old. Two termite species (dry Macrotermes subhyalinus and fresh Macrotermes bellicosus) and commercial fishmeal for poultry feed formulation that is available in the country were used as animal protein ingredients in three feeding management regimes. The birds were allocated to the three feeding treatments, with two replicates per treatment: i) treatment 1 (R1) with a diet including 2.5% of dried termites; ii) treatment 2 (R2) diet with no animal protein ingredient included, but with fresh termites given separately and the amount was depending on the daily capture; iii) treatment 3 (R3) diet including 2.5% of fishmeal. The results showed an average daily feed consumption of 65.5 g per bird. Average daily gain (ADG) for chickens was 7.7 g, 7.8 g and 7.5 g for treatment R1, R2 and R3, respectively. ADG for guinea fowl was 5.64g, 5.34 g and 5.35 g for R1, R2 and R3, respectively. Carcass characteristics studied on male guinea fowl showed a mean carcass percentage of 66.4%. Data on the taste and tenderness showed that R1 and R2 gave a better taste to guinea fowl meat, while R3 and R2 gave more tender meat. Average dry matter contents of the thighs were 42.4%, 41.8% and 40.6% for the groups R1, R2 and R3, respectively. No significant difference (p>0.05) was observed between treatments for all the parameters. Thus, dry and fresh Macrotermes spp. can be suitable animal protein ingredients that can substitute fishmeal in traditional chickens and guinea fowl feeding in rural area.Keywords: termites, fishmeal, feeding, local poultry, live weight performances, Burkina Fas

Contribution of feed supplementation to zootechnic performance of African dwarf sheep in West Africa: A review

Like gasoline is essential for a combustion engine, feed is indispensable for animals. Besides the main feed, a supplemental diet is essential, even indispensable, to help animals reach optimal production in the ruminant feeding and nutrition system. The main objective of this review was to summarize the research performed across the West Africa area on diet supplementation for African dwarf sheep. By examining some scientific articles published from 2010 to 2021, identified mainly from Scilit, Google Scholar, Elsevier, Springer Nature, PubMed, AJOL, and Scirp, we identified more than 43 feed supplements made from more than 96 local ingredients grouped into 54 agricultural and industrial by-products, seven minerals and vitamins, four fodders, and four binders and other ingredients such as enzymes. The nutritional content of most of those feed supplements based on their crude protein, crude fiber, ash, calcium, phosphorus, and gross energy contents meet recommended standards of NRC. The digestibility of the nutritional component of the feed supplement fluctuates from 20.90% (organic matter) to 94.85% (ether extract). They enabled a good average daily gain (37.03 g to 100 ga good feed conversion ratio (4.62 to 13.73). The review shows that it is possible to achieve acceptable zootechnical performance using feed supplements made with local ingredients available in each West African country

Disponibilite, Valeurs Marchande Et Nutritionnelle Des Sous-Produits Agricoles Et Agroindustriels Utilises Dans L’alimentation Des Ruminants Au Benin

The availabilities and the commercial values of 31 agricultural and agro-industrial by-products were evaluated through a semi structural interview carried out on 360 breeders of Benin. A sample of each diet was collected to determine its chemical composition and nutritive values. Maize bran, cassava peels, cakes of soya and cotton are available in any season and have a commercial value. Among fruit by-products used in the food of the ruminants, the pineapple peels occupy the first place and their commercial values are three times higher than those of the cassava peels. Soya cakes has a very high commercial value (higher than 200 FCFA/kg).The leguminous pods and the cereal hulls are also largely available but without commercial value. Roots cassava and tubers of yam by-products and the cakes are very digestible and these values do not go down below 60 %. Low values of digestibility were observed on hulls and stems of cereals and leguminous pods. These digestibilities are generally below 40 %. The groundnut haulms are more digestible than cowpea haulms (57.8 vs 49.7 %). Cotton cakes and palm oil cakes are less digestible than the other oil cakes. The digestibilities of crude protein (DCP) are very low in fruit and cereals by-products. Except for the pods of leguminous, all the leguminous by-products provided considerable quantities in DCP. The studies give opportunities of choice of food supplementation to ruminants during the dry season where graminaceous and the other herbaceous becoming rare in the natural pasture

Preweaning growth performance of Lagune cattle in Benin

The aim of the present paper was to evaluate the birth weight (BW, kg) and weaning (WW, kg) weight and the corresponding average daily gain (ADG, g) of Lagune cattle reared in the Samiondji breeding farm of Benin. A total of 1,414 records from 707 calves, born from 1997 to 2003, were analysed using a general linear procedure (proc GLM). Fixed factors were sex, calving number and year of birth. The weaning age (WAGE) was used as variable. Results of present evaluation showed that BW and WW ranged respectively from 11.65± ± ± ±0.20 to 17.40± ± ± ±0.33 kg and from 70.21± ± ± ±0.17 to 117.00± ± ± ±0.20kg while the ADG from 141.18± ± ± ±4.80 to 248.90± ± ± ±6.25g. All fixed effects significantly affected the growth traits, except sex for ADG, and year of birth for BW. The WAGE showed a significant linear relationship with ADG

The same but different: Understanding entrepreneurial behaviour in disadvantaged communities

While entrepreneurship is widely viewed as being equally accessible in all contexts, it could be questioned if potential or nascent entrepreneurs from minority and disadvantaged communities experience entrepreneurship in a similar manner to the mainstream population. This chapter examines immigrant, people with disability, youth, gay and unemployed communities to explore how their entrepreneurial behaviour might differ from the practices of mainstream entrepreneurs. What emerges is that marginalised communities can frequently find it difficult to divorce business from social living. This can have both positive and negative connotations for an entrepreneur, plus they face additional and distinctive challenges that mainstream entrepreneurs do not experience. The chapter concludes by proposing a novel ‘funnel approach’ that policymakers might adopt when seeking to introduce initiatives targeted at these disadvantaged communities

Nucleoside Reverse Transcriptase Inhibitor Resistance Mutations Associated with First-Line Stavudine-Containing Antiretroviral Therapy: Programmatic Implications for Countries Phasing Out Stavudine

Background The World Health Organization Antiretroviral Treatment Guidelines recommend phasing-out stavudine because of its risk of long-term toxicity. There are two mutational pathways of stavudine resistance with different implications for zidovudine and tenofovir cross-resistance, the primary candidates for replacing stavudine. However, because resistance testing is rarely available in resource-limited settings, it is critical to identify the cross-resistance patterns associated with first-line stavudine failure. Methods We analyzed HIV-1 resistance mutations following first-line stavudine failure from 35 publications comprising 1,825 individuals. We also assessed the influence of concomitant nevirapine vs. efavirenz, therapy duration, and HIV-1 subtype on the proportions of mutations associated with zidovudine vs. tenofovir cross-resistance. Results Mutations with preferential zidovudine activity, K65R or K70E, occurred in 5.3% of individuals. Mutations with preferential tenofovir activity, ≥two thymidine analog mutations (TAMs) or Q151M, occurred in 22% of individuals. Nevirapine increased the risk of TAMs, K65R, and Q151M. Longer therapy increased the risk of TAMs and Q151M but not K65R. Subtype C and CRF01_AE increased the risk of K65R, but only CRF01_AE increased the risk of K65R without Q151M. Conclusions Regardless of concomitant nevirapine vs. efavirenz, therapy duration, or subtype, tenofovir was more likely than zidovudine to retain antiviral activity following first-line d4T therap

bio-economic performance of chickens fed diets with dried cassava leaves (Manihot esculenta)

L’efficience des rations alimentaires à base de feuilles séchées de manioc doux a été évaluée en alimentation des poulettes pendant seize semaines. Trois rations contenant 0% (R0), 5% (R5) et 10% (R10) de feuilles séchées de manioc ont été utilisées pour nourrir 225 poussins d’un jour de souche ISA Brown répartis en groupe de 25 poussins avec trois répétitions par ration. Les gains de poids moyen quotidien (8,5 à 9,2 g/j) et les indices de consommation (IC = 7,0 à 7,58) sont similaires (P > 0,05) pour toutes les rations alimentaires. L’incorporation des feuilles, n’a pas empêché d’atteindre les besoins nutritionnels recommandés aux poulettes. Ainsi, les rations à base de feuilles séchées de manioc, n’ont pas influé sur le taux de mortalité des poulettes. Mais, elles ont permis de réduire significativement (P < 0,05) le coût alimentaire. Par rapport à la ration R0, le coût alimentaire global a baissé de 11,5% et 7,4% respectivement pour les rations R5 et R10. Sur les deux phases expérimentales, les meilleures performances bioéconomiques ont été enregistrées chez les poulettes ayant reçu la ration contenant 5% de feuilles.Valorisation des aliments non conventionels dans l'alimentation avicol

Phenotypic, socio-economic and growth features of Guinea fowls raised under different village systems in West Africa

peer reviewedIn Benin, family poultry farming has become an important activity in economic and social aspects that contribute to food security, poverty reduction and well-being. However, current information about poultry production and consumption is still limited. This information would be useful to improve the sustainable exploitation of agricultural and commercial genetic resources. We aimed to identify and assess the socio-economic and phenotypic features as well as to investigate phenotypic variability and growth performance of guinea fowls raised under different environments. Growth performance and survival rates of local guinea fowl varieties were recorded in three zones of Benin: Collines, Atacora and Borgou. Seven varieties, Gray, Common, Bonaparte, White, Black, Isabelle and Multicolored, were identified in Benin. The farmers choose a variety to be raised based on breeding system, agro-ecological zone, disease resistance, market price and production purpose. Bonaparte, Common and Gray varieties emerged as the most resistant whereas White, Black and Gray outperformed in growth and may be used for breeding purposes. The semi-confinement system could be recommended for startup as a temporary solution to improve production of local guinea fowls in Benin. The existence of several varieties on farms does not encourage genetic conservation and improvement of these resources. Establishing selection or crossbreeding programs in controlled environments would be more appropriate for guinea fowls raised in Benin.Caractérisation phénotypique des populations de pintades (Numida meleagris) locales élevées au Béni
