In Vietnam, 84% of the 188 million chickens are indigenous. The following local breeds are recorded: Ri, Mia, Te, Tau Vang, Ac, Oke, H’mong, Tre, Choi, Phu Lu Te, To, Dan Khao, Ho, Dong Tao and Van Phu. Mia, Ho and Dong Tao are reported as endangered or critical, while the Van Phu breed could have been lost during the last years. The phenotypes of the Mia and Ri breeds are described as quite close. The objective of this study is to characterize phenotypically Ri and Mia chickens. The morpho-biometric characterization was conducted according to the recommendation of FAO (1981). A total of 227 adults Ri (174 females and 53 males) and 53 adults Mia (18 males and 35 females) were used for the study. The following colors were observed for Ri and Mia respectively: tan (43.17% and 37.73%), gold salmon (24.23% and 26.42%), wheat (15.42% and 26.42%), dark red (9.69% and 5.66%), silver salmon (3.52% and 3.77%) and copper black (3.96% and 0%). Comb was mostly simple (91.19% and 100%) and red (100% and 100%) for both breeds. The wattles were of the same color as the comb while the color of the legs was yellow. The weights of adult males (2433.89g) and females (1752.86g) of the Mia breed were significantly higher than those of Ri (2053.02g and 1459.22g for males and females respectively). The results show that the external aspect of both breeds is not very different while body weights in the Ri breed were found lower than in the Mia breed. [less ▲]

As part of the genetic improvement of production, selection of breeds (purebred selection) on the one hand and crossbreeding, exploiting the complementarity between breeds and hybrid vigor or heterosis other hand, are methods choice used by animal husbandry. The pure breeding as practiced in the developed world, based on the individual performance of breeding as well as the placement of the offspring, uses expensive infrastructure and significant human resources. In addition, genetic progress is slow and must be sustained effort. For all these reasons, in the less favored regions of the world, although the intra-breed selection is operational, most stakeholders are most often uses the crossbreeding technique leading to immediate results and protecting local breeds. Thus, in dairy cattle, many countries have used the Holstein, Brown in the Alps, and the Montbéliarde Normande with varying success. In the meat sector, in cattle, swine and sheep, as well as in the area of ​​poultry meat, crossing indigenous breeds with exotic breeds imported leads to interesting results. In the Walloon Region, due to the hard work of breeders, animals have emerged exceptional and, in cattle, swine and sheep, they are in fact, more muscular animals in the world. Thus, bulls Belgian Blue reared under natural conditions, have average daily gains as high as 2000 g / d with yields close to slaughter 70% Pietrain pigs reach values ​​of the performance slaughter of around 83% and the yield values ​​as high as 59% were observed in Texel sheep. All these animals have the characteristic of being very efficient while presenting carcasses with more muscle, less fat and less bone. As for local poultry type Ardennaise, it has remarkable phenotypes leading to immediate traceability (black members), more than 150 eggs per clutch and a darker meat.The author gives in detail examples of the use of crossbreeding with cattle, sheep, pig and poultry all originated from the Walloon Region of Belgium.

Backyard poultry is considered as a powerful tool for poverty alleviation. It is further promoted as a way of empowering women in communities where there is gender bias in poultry raising. The low-input systems involved are based on local breeds that are perfectly suited to their environment. However, socio-economic processes put local genetic resources under pressure, leading to the erosion of biodiversity. The present survey addresses this issue in the case of Kabylie, a mountainous coastal region of Algeria, through a survey conducted in 90 households raising poultry, a morpho-biometric description of 315 local chickens, and a performance evaluation of both growth and egg production in experimental semi-intensive conditions. The socio-economic profile of poultry smallholders in Kabylie reveals poor education and high diversification of agricultural assets and confirms gender bias in poultry keeping. The erosion of local genetic resources in chicken is found to be severe despite their cultural importance in Kabylie. From complementary surveys among experienced poultry keepers, the major original local type is postulated to consist of three varieties with black plumage (pure black, mottled and barred). The performance evaluation raised promising results, suggesting that some degree of improvement of low-input backyard systems could be pursued by exploiting the local breed. Finally, a strategy for a revival of the local breed through the support of the most involved smallholders is outlined in accordance with the information collected in the survey. [less ▲]

Dans le contexte de valorisation de la biodiversité avicole, ce travail se propose de poser les bases d’une réhabilitation des poules locales Vietnamiennes, particulièrement adaptées aux conditions d’élevage peu intensives de ce pays. La grande importance socioéconomique et culturelle de ces races pourrait être renforcée et exploitée à des fins de développement rural par la promotion de filières de qualités différenciées. De telles évolutions nécessitent de caractériser le potentiel de production de ces races sur le plan qualitatif. Cette étude a pour objectif l’étude de la qualité des œufs des races de poules vietnamiennes Ri et Mia. La première est la poule la plus répandue au Vietnam et la deuxième est une race menacée d’extinction. Dix neuf caractères de qualité externe et interne de 90 œufs de la poule Ri et 60 œufs de la poule Mia ont été mesurés à 40 et à 60 semaines. Le poids entier moyen des œufs de la Mia (44,70g) était significativement (p<0,001) supérieur à celui de la poule Ri (41,68g). Le rapport jaune/blanc n’était pas significativement (p>0,05) différent à l’âge de 40 semaines (Ri : 0,55 ; Mia : 0,58). À l’âge de 60 semaines, ce rapport devient significativement supérieur pour les œufs Mia alors que celui des œufs Ri (0,64 vs. 0,57 ; p<0,05). Aucune différence significative (p>0,05) n’a été enregistrée entre les deux races pour les paramètres de fraîcheur des œufs (unités d’Haugh et pH des blancs et des jaunes) et de résistance des coquilles (force maximale de rupture). Malgré le faible effectif de cette étude, des différences significatives entre les performances de production ont été observées entre ces deux races phénotypiquement et génotypiquement proches.

Face à la hausse rapide de la consommation mondiale de viande de volaille et afin de s’inscrire dans la perspective d’un développement durable, l’aviculture a connu et connaîtra encore de profondes mutations. L’expansion rapide de l’élevage intensif de souches hybrides, génétiquement uniformes, se réalise au détriment des races locales de poules. Ces dernières constituent pourtant un outil central du développement socio-économique rural dans diverses régions du monde. Le but de cette étude est d’étudier les performances de croissance du Poulet Kabyle en production intensive. L’expérimentation s’est déroulée dans la Région de Basse Kabylie et a consisté en deux essais consécutifs de mars à juin 2010 (n=150 poussins) et d’août à novembre 2010 (n=155 poussins). À l’éclosion, le poids moyen des poussins de la première répétition (mâles : 41,29 g, femelles : 36,26 g) n’était pas significativement différent (p>0,05) de celui de la deuxième répétition (mâles : 37,30 g, femelles : 31,94 g). A la fin de l’expérimentation, les poulets de la première répétition présentaient un poids significativement (p<0,05) supérieur à ceux de la deuxième répétition (mâles : 1978,93 g, femelles : 1448,57 g vs. mâles : 1803,30 g, femelles : 1234,48 g). L'étude des différents paramètres de la courbe de croissance (modèle de Gompertz) a révélé des valeurs différentes selon le sexe et la répétition. Aucune différence significative (p>0,05) n’a été observée entre les mortalités, les poids moyens à l’abattage, les rendements, les pH des muscles, des animaux des deux répétitions. Le poids moyen à l’abattage des mâles et leur rendement a été significativement (p<0,05) supérieur à celui des femelles. Les pH des muscles se stabilisent à une valeur appelée pH ultime variant de 5,68 à 5,81. [less ▲]

La qualité de l’œuf de poule et les performances de ponte peuvent varier en fonction de la race. Dans les systèmes d’élevage extensifs à semi-intensifs des pays en développement, le croisement entre une race de poule locale et une souche industrielle pourrait constituer une opportunité, délivrant un produit commercial alliant rusticité et performances zootechniques. Dans un contexte mondial d’érosion de la biodiversité avicole, ce type de croisement apporte une motivation économique à la conservation de la lignée parentale locale. Le but de cette étude est de comparer le taux de ponte et la qualité des œufs, en termes de composition, de la race de poule locale Kabyle (KAB) et de son croisement (ISAKAB) avec la souche industrielle Isa-Brown (ISA). Les analyses sur la qualité des œufs ont été réalisées durant trois périodes (semaines 35 à 36, 50 à 51 et 65 à 66). L’âge d’entrée en ponte était significativement supérieur pour la poule Kabyle par rapport au croisement ISAKAB (165,96 jours vs. 140,76 ; p<0,0001). Le nombre d’œufs pondus annuellement par la poule ISAKAB est significativement supérieur (194,20 vs. 173,44 ; p<0,05) Le rapport jaune/blanc était identique pour les deux races comparées, avec une moyenne globale de 0,56. Le poids de l’œuf était supérieur chez la poule ISAKAB (53,55 vs. 48,86 ; p<0,0001). Dès lors, les performances de ponte et la qualité des œufs de la poule Kabyle ont été améliorées par le croisement avec la souche Isa-Brown. [less ▲]

La République Démocratique du Congo (RDC) souffre, à l’instar d’une majorité de pays africains, d’une précarité alimentaire conséquente. Le développement du secteur de l’élevage y est une pièce importante de la stratégie de lutte contre cette insécurité alimentaire, par l’apport de protéines de haute qualité aux populations pauvres ainsi que plus globalement par la création de richesses et la diversification du secteur agricole. A ce titre, le secteur avicole offre incontestablement, par son cycle de production court, une solution rapide et abordable par le plus grand nombre. Cette étude aborde les contraintes à la production de la poule locale au Bas-Congo. Plusieurs facteurs y sont identifiés, tels que les pathologies, l’alimentation, l’habitat et les prédateurs. L’amélioration de la situation économique et nutritionnelle des paysans de la Province du Bas-Congo peut être envisagée en améliorant le potentiel de production des poulets de race locale. Afin d’y arriver, une attention particulière doit être accordée à une alimentation équilibrée et une meilleure conduite générale de l’élevage, incluant un accès aux soins vétérinaires. L’amélioration génétique des races locales est également une voie envisageable, pour autant que l’adéquation entre l’animal et le cadre de son élevage soit respectée. [less ▲]

Testing period started at an average age of 60 days and ended at an average age of 225 days. The growth performances were weights at starting and finishing periods, average daily gain, backfat thickness, longissimus depth and lean content. The sperm quality was assessed using ejaculate volume, spermatozoon motility, sperm concentration, total number of spermatozoon in the ejaculate, rate of abnormal spermatozoon and pH of sperm. All these measurements were used to compare the genetic groups. The results showed that: The average daily gain of stress negative Piétrain boar purebred was not significantly different from Piétrain hybrids while the lean content was higher. The ejaculate volume and the spermatozoon motility of stress negative Piétrain purebred boars were higher than Piétrain hybrids but the sperm concentration and the total number of spermatozoon in the ejaculate were lower.

The consumption of wildlife meat is an important source of animal protein for rural and urban population in Congo. A survey on bushmeat trade was undertaken in 21 municipal markets during four weeks, in Brazzaville. The objective of this study was to define the traders’ profile and to evaluate the quantities of games and meat merchandised on the municipal markets. The study methodology combined two approaches: a quantitative one using a questionnaire as principal tool for collecting data, and a qualitative one associating informal survey methods via individual or group interviews. The results showed that women were the most involved in this trade (52%). Markets trader’s monthly income was estimated at 210,428 (US$420) ± 49,128 (US$98,256) FCFA. On average, the bushmeat traders’ were 39 ± 10 years old and 69% of them attended the two levels of secondary education. During four weeks, 3,711 animal carcasses were recorded on the 21 surveyed markets, representing almost 35,790 kg of biomass. Overall, 35 animal species were identified, including 9 the hunting of which was prohibited. The mammals constituted 93.8% of total number of hunted animals, with three dominant orders as the artiodactyls (49.2%), the rodents (22.6%) and the primates (17.7%), of which the Cephalophus, the Potamochoerus, the Atherurus and the Cercopithecus were the most represented. It was also noticed that trapping, an activity which leads to great losses, becomes very important, followed by be helpful alternatives to meet Congolese demand for bushmeat. For a sustainable management of the Congo’s faunic resources, this study suggests the introduction gun-hunting. The Congo-Ocean Railway and the National Road n°2 were used regularly in the transportation of game, to a 72% level. The district of Niari, Lekoumou, Sangha and Pool were the main sources of supply. At the present time, the meat quantities offered in Brazzaville markets don’t seem to be reduced because hunting areas extend always further, often to the detriment of protected areas. Despite the fact that such business squarely growths and shows evidence of overexploitation, activities promoting game farming and breeding of domestic species, in Brazzaville suburbs, are needed to mitigate the impact of bushmeat trade.

A total of 395 tail samples of stress negative Piétrain new born piglets from the pig farm of Dong Hiep Haiphong were used to determine halothane genotypes (CC, CT and TT) in order to study the effect of mating type (♂CC×♀CC, ♂CC×♀CT, ♂CT×♀CC, and ♂CT×♀CT) on halothane genotype frequencies. Effects of genotype on live weight (174 pigs of 2 month old, 96 pigs of 5.5 month old), back fat thickness, loin muscle thickness and lean percentage (117 pigs), average daily gain (89 pigs) were also studied. Results showed that the mating type affected halothane genotype frequencies in the progeny. For the mating type ♂CC×♀CT and ♂CT×♀CT, the genotype containing allele T was reduced in the next generation; in the rest two genotypes (♂CC×♀CC and ♂CT×♀CC) the halothane allele frequency in the offspring was consistent with the theoretical frequency. The halothane genotypes CC and CT did not affect live weights at 2.0 and 5.5 months of age, average daily gain, backfat thickness, loin muscle thickness and lean percentage. [less ▲]

An intracellular symbiotic bacterium was isolated from the flora of a natural clone of the black bean aphid Aphis fabae. The strain was able to grow freely in aerobic condition on a rich medium containing 1% of each of following substrates; dextrose, yeast extract and peptone of casein. Pure culture was achieved through the use of solid-phase culture on the same medium and was designated CWBI-2.3T. 16S ribosomal DNA sequence analysis revealed that CWBI-2.3T strain was a member of the gamma-3 subgroup of the class Proteobacteria, having high sequence identity (>99%) with the R-Type of secondary endosymbiont found in several aphid species Serratia symbiotica. As strain CWBI-2.3T (=LMG 25624T =DSM 23270T) was the first R-type symbiont to be isolated and characterized, we proposed to designate it as the type strain of Serratia symbiotica species. [less ▲]
