Mortiño (Hesperomeles goudotiana (Decne.) Killip) and Uva Camarona (Macleania rupestris (Kunth) A.C.Sm.) are two native species of the high Andean ecosystems that are found both in wooded areas, in roads and homegardens in the rurality of Bogotá. Although their food use as wild berries is traditional and well known among high mountain peasant communities, the sociocultural factors associated with agri-food systems of this kind of species and its commercialization in large-scale populated centers have not been analyzed. In this research, semi-structured interviews were carried out in 17 rural areas of Bogotá, 12 urban public market places were visited, as well as representatives of restaurants and networks of solidarity-based commercialization in Bogotá who have introduced these species in their offer were interviewed. As a result, a compilation of the knowledge associated with Mortiño and Uva Camarona is made and a description of its circulation in agri-food circuits from its collection in the field to its final destinations in the Bogotá urban area. Additionally, the relationship between the commercialization of these species, the conservation of the biocultural memory and the socioeconomic opportunities that its promotion and sustainable management would have at the local scale are analyzed.

Killip) y la Uva Camarona (Macleania rupestris (Kunth) A.C.Sm.) son dos especies nativas de los ecosistemas altoandinos que se encuentran tanto en áreas boscosas como en caminos y huertas de la ruralidad de Bogotá. Aunque su uso alimenticio como frutos silvestres es tradicional y bien conocido entre las comunidades campesinas de alta montaña, no se han analizado los factores socioculturales asociados con los sistemas agroalimentarios y cadenas de suministro de este tipo de especies y su comercialización en centros poblados a mayor escala. En este estudio, se realizaron entrevistas semi-estructuradas en 17 veredas de la ruralidad de Bogotá, se visitaron 12 plazas de mercado públicas urbanas y se entrevistaron a representantes de restaurantes y redes de comercialización solidaria en Bogotá que han introducido estas plantas en su oferta. Como resultado, se hace una recopilación de los saberes asociados con el Mortiño y la Uva Camarona y una descripción de su circulación en sistemas agroalimentarios desde su recolección en campo hasta sus destinos finales en el área urbana de Bogotá. Adicionalmente, se analiza la relación entre la comercialización de estas especies, la conservación de la memoria biocultural y las oportunidades socioeconómicas que tendría su promoción y manejo sustentable a escala local.

Une étude de l’effet de l’incorporation des graines d’Hibiscus Sabdariffa L. dans la ration alimentaire sur quelques paramètres d’ingestion et de croissance du poulet en aviculture traditionnelle améliorée a été conduite sur 120 animaux au Burkina Faso. Le maïs, source habituelle d’énergie et de protéines de la ration, a été substitué par la farine de graines crues de Hibiscus sabdariffa à raison d’un taux d’incorporation de 0 % ; 10 % et 20 %. L’incorporation des graines crues d’Hibiscus sabdariffa s’est traduite par une réduction significative des paramètres de croissance, d’ingestion, d’efficience alimentaire des nutriments des aliments expérimentaux. Cette diminution s’est faite de manière proportionnelle au niveau d’incorporation. L’étude a révélé que les teneurs en substances anti nutritionnelles et de cellulose des graines crues d’Hibiscus sabdariffa pourraient constituer un facteur limitant pour leur incorporation dans les aliments des volailles. A cet effet le niveau maximal d’incorporation devrait être limité à 10 %.Mots clés: aviculture traditionnelle améliorée ; graines de Hibiscus sabdariffa ; poulets ; aliment non conventionnel, Burkina FasoEnglish Title: The impact of intake of Hibuscus sabdariffa’s seeds (Guinea sorrel) in the feeding over some parameters of indigestion and growth of chickens in traditional improved poultry farming/ Aviculture in Burkina FasoEnglish AbstractA survey on the impact of in take of Hibuscus sabdariffa L. seeds (Guinea sorrel) in the feeding over some parameters of indigestion and growth of chickens in traditional improved poultry farming/ aviculture has been conducted on 120 chickens in Burkina Faso. Maize, which provides proteins in the food, is substituted by crude Hibuscus sabdariffa seeds’ flour in a ratio of intake of 0 %, 10 % and 20 %. Pecking crude Hibuscus sabdariffa seeds resulted in an important reduction of growth, indigestion and food efficiency parameters of nutriments. This reduction occurred proportionally to the intake level. The survey revealed that the Cellulose contents of anti-nutriments of Hibuscus sabdariffa’s seeds could a limitation factor in poultry food ; then the maximum level of intake should not exceed 10 %.Keywords: improved traditional poultry farming ; seeds of Hibiscus sabdariffa ; chickens ; non-conventional food ; Burkina Faso

The objective of this study was to determine the chemical and energy composition of spirulina (Spirulina platensis), the nutrient metabolizability coefficients, and the values of apparent metabolizable energy (AME) and the apparent metabolizable energy corrected for nitrogen balance (AMEn) in broilers. A digestibility trial was carried out by using total excreta collection method, with 90 Cobb 500 lineage chicks, with initial weight of 256 ± 5 g at 11 days of age. Birds were allotted in metabolic cages for 10 days, distributed in a completely randomized design, with three treatments and six repetitions with five birds each. Diets consisted on a reference-ration based on corn and soybean meal and two test diets, one containing spirulina (30%) and the other one with soybean meal (30%). Spiruline was superior to soybean meal for contents of dry matter (DM), gross energy (9.60%), crude protein (26.56%), ether extract (54.45%), mineral matter (42.77%), calcium (100%) and total phosphorus (130.77%) and also for most amino acids, except lysine, glutamate, histidine and proline. Nevertheless, spiruline presented lower values of gross fiber (83.95%), acid detergent fiber (85.12%) and neutral detergent fiber (6.15). The AME and AMEn values (kcal/kg of DM) were, respectively, 2,906 and 2,502 for the spirulina and 2,646 and 2,340 for the soybean meal and AMEn of spirulina was 6.92% higher than soybean meal. Objetivou-se determinar a composição química e energética da espirulina (Spirulina platensis), os coeficientes de metabolizabilidade dos nutrientes e os valores de energia metabolizável aparente (EMA) e aparente corrigida pelo balanço de nitrogênio (EMAn) em frangos de corte. Realizou-se um ensaio de digestibilidade utilizando-se a metodologia de coleta total de excretas com 90 pintos machos da linhagem Cobb 500, com peso inicial de 256 ± 5 g aos 11 dias de idade. As aves foram alojadas em gaiolas de metabolismo durante dez dias, distribuídas em delineamento inteiramente casualizado, com três tratamentos e seis repetições, cada uma com cinco aves. As dietas consistiram de uma ração-referência formulada à base de milho e farelo de soja e duas rações-teste, uma contendo espirulina (30%) e outra com farelo de soja (30%). A espirulina foi superior ao farelo de soja quanto aos conteúdos de matéria seca, energia bruta (9,60%), proteína bruta (26,56%), extrato etéreo (54,45%), matéria mineral (42,77%), cálcio (100%) e fósforo total (130,77%) e também para a maioria dos aminoácidos, exceto lisina, glutamato, histidina e prolina. No entanto, apresentou menores valores de fibra bruta (83,95%), fibra em detergente ácido (85,12%) e fibra em detergente neutro (6,15%). Os valores de EMA e EMAn (kcal/kg de MS) foram, respectivamente, 2.906 e 2.502 para a espirulina e 2.646 e 2.340 para o farelo de soja, e a EMAn da espirulina foi 6,92% superior à do farelo de soja.
