L’aulacodiculture est une option privilégiée à la fourniture de protéines animales. Cette étude a été menée dans le but de déterminer l’effet d’un aliment granulé sur les caractéristiques organoleptiques et biochimiques de leur viande. Ainsi, un lot d’aulacodes a été nourri au granulé tandis que l’autre nourri au fourrage avec complément alimentaire (aliment classique). Après un abattage normal, les membres antérieurs et postérieurs des animaux ont été prélevés. La viande des membres postérieurs a été retenue pour l’analyse organoleptique (couleur, texture, jutosité, flaveur, tendreté) par 12 panelistes en trois répétitions. La viande des membres antérieurs a servi à la détermination de la matière sèche, des protéines brutes, de la matière grasse et des cendres brutes. Ces travaux montrent que la viande d’aulacode est juteuse, tendre avec une texture grossière et une flaveur prononcée quel que soit le type d’aliment. Le profil sensoriel montre une différence tant au niveau de la couleur qu’au niveau de la jutosité et de la texture. Quant aux paramètres biochimiques, aucune différence significative n’a été observée (p ≥ 0,05). Il convient de retenir que la viande d’aulacodes nourris au granulé a été plus appréciée tant pour la couleur, la texture, la jutosité que pour la flaveur. Mots clés : Aulacodes, viandes, granulé, fourrage, Côte d’Ivoire.   English Title: Some organoleptic characteristics and nutritional values and nutritionals values of meat of Thryonomys swinderianus, (Temminck, 1827) raised in captivity and fed with two types of foodGrasscutter farming seems to be a preferred option for the supply of proteins formerly derived from hunting. This study aimed at determining the effect of a granulated food on the organoleptic and biochemical qualities of grasscutter meat. Thus, three grasscutters were randomly selected from a batch of animals fed with a granulated food and the other three from the batch fed with the conventional food. After normal slaughter, the fore and hind limbs were removed. The meat of the posterior limbs was selected for organoleptic analysis by a panel of 12 consumers in three repetitions. The meat from upper limbs was used to evaluate the biochemical parameters such as dry matter, crude protein, fat and raw ash. Results showed that the meat of the grasscutter was juicy, tender with a coarse texture and a pronounced flavor whatever the type of food. The sensory profile showed a significant difference in color, juiciness, and texture of meat. With respect to biochemical parameters, no significant difference was observed (p ≥ 0.05). The type of food had no effect on biochemical parameters of grasscutter meat. However, the organoleptic parameters influenced significantly the level of appreciation of grasscutter meat.

Aims: Maize (Zea mays L.) is a major staple food for millions of people in Côte d’Ivoire. Due                         to its high productivity and low cost of calorie it is preferred crop for food security of the                      country. Thus, this study was conducted to assess nutritive quality of maize produced and               stocked in five purposively selected regions of Côte d’Ivoire which represents five agroecological settings. Study Design: A total of 1500 samples of maize as grains, epis and spathes were collected at rate of 500 samples by region (Gbêkê, Poro, Hambol, Indénié-Djuablin and Gontougo) and sent to the laboratory in order to analyse their nutritional quality. Place and Duration of Study: This study was carried out during March 2016 to January 2017. The collected sample were carried out at the laboratory unit of Food Sciences and Biochemistry of the Félix Houphouët-Boigny University, Abidjan. Methodology: Proximate analyses were carried out using standard methods AOAC (2000). Results: The results show significant difference from the biochemical compositions of maize type and region. Mean value intervals were as follow: dry matter (85.83 – 91.42%), ash (1.19 - 2%), proteins (7.99 - 9.32), lipids (3.21 - 4.47), carbohydrates (71.80 - 77.94), starches (62.30 - 68.44%), fibers (5.03 - 5.83%), total sugars (2,13 - 2.99%), reducing sugars (0.33 - 0.66%), free fat acidity (1.86- 4.50%), peroxide value (1.34 - 3.07 meq O2/kg), iodine value (100.93 - 130.56 g I2/100 g), unsaponifiable (0.89 - 1.54%) and energy values (357.88 - 374.39 kcal). Conclusion: A significant variability from one region to another can be noticed at level of maize quality regardless the type of maize. The nutritive quality of maize seems to be tied to postharvest treatments (drying), type of storage (epis, grains and spathes) and structure of storage.

RESUME Objectif : Cette étude a été menée pour évaluer le niveau de la pourriture brune, de suivre son évolution dans les plantations, au niveau des différentes parties du cacaoyer et de préciser l’emplacement des lésions sur les différentes cabosses infectées dans les cacaoyères dans le Département d’Aboisso Sud-est de la Côte d’Ivoire. Méthodologie et résultats : Cinq plantations ont été choisies avec dans chacune vingt plants mis en observation et sur lesquels trois parties ont été délimitées : le bas, le milieu et les branches. Sur chaque cabosse infectée la lésion est soit, proximale, latérale ou distale. Le dispositif est donc en blocs de Fischer avec un arrangement factoriel, 2 facteurs (localisation des cabosses dans l’arbre et la position des lésions sur les cabosse) avec chacun 3 niveaux soit, 9 traitements avec 5 répétions. L’analyse des taux des affections à Phytophthora donne une différence hautement significative d’une part entre les localisations des cabosses dans l’arbre et d’autre part, entre les positions des lésions sur les cabosses. Aussi, la position des lésions sur les cabosses diffère-t-elle selon la localisation de celles-ci dans l’arbre (p-value < 1%). Conclusion : La pourriture brune sévit de façon endémique dans le département d’Aboisso. Les cabosses sur le tronc, notamment celles qui sont vers le bas, s’avèrent les plus vulnérables. Les lésions distales sont préférentiellement situées sur les cabosses vers le bas du tronc, alors que les proximales sont en grand nombre sur le milieu du tronc et les branches. Les Phytophthora étant des organismes telluriques, l’importance de leurs attaques sur les cabosses et sur les parties de celles-ci proches du sol, source d’inoculum primaire s’avérerait inévitable. Application actuelle et potentielle des résultats : A partir de ces résultats, il convient de recommander d’éviter l’abandon de la protection avec des fongicides appropriés de la cacaoyère de cette localité comme ont tendance à le faire certains planteurs. Aussi, les applications de fongicides, surtout ceux de contact, par atomisation ne doivent-ils pas être dirigées seulement dans les branches mais également sur le tronc et surtout vers le bas des pieds des arbres. Mots clés : pourriture brune, dynamique, cacaoyer, Aboisso, Côte d’Ivoire ABSTRACT Spatio-temporal dynamics of the brown rot of cocoa pots due to phytophthora sp. in the department of Aboisso (Cote d'Ivoire) Objective: This study was conducted to evaluate the level of brown rot, monitor its evolution in plantations, at the level of different parts of the cocoa tree and to specify the location of the lesions on the different pods infected in the cocoa farms in the Department. of Aboisso South-east of Ivory Coast. Methodology and results: Five plantations were selected, each of which had twenty plants under observation and on which three parts were delineated: the bottom, the middle and the branches. On each infected pod the lesion is proximal, lateral or distal. The device is therefore in Fischer blocks with a factorial arrangement, 2 factors (location of the pods in the tree and the position of the lesions on the pod) with each 3 levels, i.e. 9 treatments with 5 repetitions. The analysis of the Phytophthora disease rates gives a highly significant difference between the location of the pods in the tree and between the positions of the lesions on the pods. Also, the position of the lesions on the pods differs according to the location of these in the tree (p-value <1%). Conclusion: Brown rot is endemic in the Aboisso department. Pods on the trunk, especially those that are down, are the most vulnerable. The distal lesions are preferentially located on the pods down the trunk, while the proximal ones are in large numbers on the middle of the trunk and branches. Phytophthora being telluric organisms, the importance of their attacks on pods and parts of them that are close to the soil, a source of primary inoculum, would be inevitable. Current and Potential Application of Results: From these results, it is advisable to avoid abandoning the protection with appropriate fungicides of the cocoa farm in this locality, as some planters tend to do. Also, the applications of fungicides, especially those of contact, by atomization should not be directed only in the branches but also on the trunk and especially down the feet of the trees.

Background: The testis-specific serine/threonine protein kinase (TSSK2) is an indispensable protein responsible for the mobility of spermatozoa expressed specifically in the germ cells during spermatogenesis and present in the mature spermatozoa. Its gene mutation could constitute a risk of infertility. The aim of this study is to investigate the polymorphism of this TSSK2 gene in men with asthenozoospermia.Methods: The ejaculates were obtained from patients attending the reproductive biology unit of Institut Pasteur of Côte d’Ivoire for their spermiological evaluations. The semen analyses are performed with the automatic sperm analyzer SQA-Vision. 30 sperms, including 20 asthenozoosperms and 10 normosperms, were selected from their spermiological results and the spermatozoa DNA was extracted by the phenol/chloroform method. Direct Sequencing of the spermatozoa DNA fragments was done using the Sanger method. The frequencies of mutation were analysis with the Fisher and Mann-Whitney tests.   Results: It was revealed 17 mutations in 22 ejaculates. The frequent mutations are c.839C>T (T280M), c.816G>C (L372L), c.1026G>A (R342R), c.785A>C (H262P) and c.80A>G (K27R) with respectively frequencies of 50.0%, 26.67%, 16.67%, 13.33% and 10.0%. The analysis of these mutations indicated a significant difference in the frequency of occurrence of mutations between normosperms and asthenozoosperms (p-value = 0.01).Conclusions: This study shows that mutations in the TSSK2 gene are more common in asthenozoosperm ejaculates than normosperm ejaculates. This fact suggests the probable association of mutations in the TSSK2 gene with asthenozoospermia.

Blighia Sapida

In this work, comparative study of physicochemical properties and fatty acids of dried arils (DA) oil and those roasted (RA), of Blighia sapida from Côte d’Ivoire have been done using usual methods. The results showed that the crude fat obtained were 59.08± 0.02 g/100 g for dried arils (DA) and 60.51 ± 0.12 g/100 g for roasted arils (RA) respectively. Physicochemical properties of these oils were equal approximately, except level of saponification (241.19 mg KOH/g (DA) against 216.8 mg KOH/g (RA)); acid value (7 mg KOH/g (DA) and 6.28 mg KOH/g (RA)) and ester acid 234.19 mg KOH/g (DA) against 210.65 mg KOH/g (RA) where variances analysis showed that there was significant difference (p<0.05). On the other hand, refractive index, pH, moisture value, relative density and Free fatty acid were respectively; 1.465 (DA) and 1.475 (RA); 5.625 (DA) and 5.8 (RA); 1.757 (DA) and 1.9 (RA); 0.093 (DA) and 0.103 (RA), 3.52 mg KOH/g (DA) and 3.03 mg KOH/g (RA). The color of both oils was yellow. Fatty acid profile of these arils oils revealed that values of DA and RA were equal approximately (variances analysis showed that there was no significant difference (p<0.05)). These arils oils contained high levels of unsaturated fatty acids, 64.10 % (DA) and 65.17 % (RA), especially linolenic acid 20.02 mg/100 g (DA) and 22.18 mg/100 g (RA); linoleic acid 15.37 mg/100 g (DA) and 16.83 mg/100 g (RA) and Oleic acid 12.76 mg/100 g (DA) and 13.21 mg/100 g(RA). The saturated fatty Acids, accounted for 35.90% (DA) and 34.83% (RA) were constituted by palmitic acid with 18.02 mg/100 g (DA) and 18.11(RA) which were higher values. The values of stearic acid were 7.1 mg/100 g (DA) and 7.9 mg/100 g (RA) and 1.85 mg/100 g (AD) and 1.9 mg/100 g (RA) mg/100 g for myristic acid respectively. These results showed that the arils oils of Blighia sapida fruit from Côte d’Ivoire have highly nutritive fat content because rich in essentials fatty acids. These oils may be suitable for soap making and edible (margarine). The oils extracts exhibited good physicochemical properties and could be useful as edible oils and for industrial applications.

Pyrrolizidine Alkaloids (PAs) are toxic for human and livestock. Several outbreaks in human intoxications were reported worldwide. This study aimed at assessing the presence and quantifying the PAs in some Asteraceae, Boraginaceae and Leguminosae used in traditional medicine in Côte d'Ivoire. TLC detection with Ehrlich reagent (method of Mattocks) and spectrophotometric dosage were used to analyze 21 plants species. All the studied plants showed at least trace amount of PAs except Caesalpinia bonduc, Parkia filicoidea and Pilostigma thonningii. The contents obtained ranged between 0.261 and 1.518 mg/ml. However, for the majority of the studied plant species, there was a significant difference between aqueous and methanol extracts. The richest species were Heliotropium indicum, Tridax procumbens and Vernonia colorata. The presence of PAs in the studied plants is an indication of people exposure to probable toxicity. This raises the need for an evaluation of the risk related to the consumption of such medicinal plants in Côte d'Ivoire.

Objective: The aim of this work was to determine the processing aptitude of maize varieties into food products to be promoted in Côte d’Ivoire. Methodology: Three dishes have been developed from ten maize varieties (MAAN16, PGBR, PGB18, AAA3, KF18, CJB, KO/Na4, KO/Na3, KO/Wa6, and EV99MRP). The sensory criteria used for the acceptability of the food products were the taste, the flavor and the color. Prior to the preparation of maize flour based food, like cakes, cooked flour paste (tôh) and semolina porridge,  the biochemical and physicochemical characteristics (moisture content, fat, protein content, ash content, carbohydrate, total sugar and reducers and pH) and functional characteristics of maize were determined. Hedonic   and descriptive tests were performed   with 30 and 15 panelists respectively. Results: The maize varieties presented good nutritional and technological potentialities because of their high content in essential compounds likely to influence the organoleptic characteristics of the processed food.  The lowest starch content was MAAN16 with 38.58 ± 0.45% dw and the highest was CJB with 71.85 ± 0.56% dw. The lowest protein content is 5.56 ± 0.17% dw at CJB and the highest protein content is 13.66 ± 0.33% dw in KO/Na3. The lowest fat content is 3.87 ± 0.12% dw (in KO/Na4) and the highest is 12.56 ± 0.50% dw (in MAAN16); the lowest carbohydrate level is 63.27 ± 0.01% dw (in MAAN16) and the highest is 74.92± 0.03% dw (in CJB). The acceptability of the cakes, the cooked flour paste and the semolina porridge depended on the maize variety. Foods prepared from maize varieties CJB, KO/Na3, KO/Wa6, MAAN16 and PGBR were the most appreciated by tasters.

The diet of Hemichromis fasciatus (Perciformes, Cichlidae) was studied in the lake dam of Ayame 2 (Côte d'Ivoire) from September 2015 to August 2016. A total of 141 specimens were captured using gill nets and hawks. The relative importance of food index has been calculated to assess the relative abundance of the preys. The standard length of fish varied between 70 mm and 250 mm. The global percentage of emptiness and intestinal coefficient mean were 23.40 % and 1.35 ± 0.48 respectively. The food spectra constituted of fishes, insects, arachnids and plants debris showing that this species an omnivorous fish with predatory fish tendency. The comparison of the food habits between size ranges (LS ≤ 110 mm and LS ˃ 110 mm) did not show any significant difference. But, a significant variation of the diet according the sexes and seasons was observed.
