Summary

The study pertains to phenotypic characterization of some breeds of duck (common white duck and Indian runner duck), Muscovy ducks (black and white feathered and sepia feathered) besides two breeds of geese (white and brown feathered and white feathered) reared in the state of West Bengal (India). The study was conducted at five locations of the state and comprised 1395 ducks and 600 geese. The data were analysed statistically using mainly descriptive statistics, the differences in mean were analysed using Duncan's multiple range test. Both qualitative and quantitative traits were considered in the study. The qualitative traits were shank colour, bill colour, colour of the feathers, skin colour, egg shell colour, the presence or absence of beans, body carriage, bill type and colour of the eyes, while the quantitative traits included in the study were weight of the ducks and weight of the eggs. Some production traits such as numbers of eggs laid per year and dressing percentage of the drakes and ganders of each breed too have been studied. The ducks and geese are raised under semi-intensive management system and mostly depend on scavenging for their nutritional needs. This results in poor egg production and at times loss of stock because of diseases. The study regarding average egg production indicated that the Muscovy ducks and the geese have poor egg production, whereas the Indian runner followed by the common white duck are potentially the best. The ducks are important source of earnings for the small holder farmers and are raised both for meat and eggs, while the geese are reared mostly for ornamental purpose. However, the populations of the ducks are fast dwindling because of avian influenza in the region and because restocking is mostly being carried out with less adapted Khaki Campbell ducks. This happens mainly because the government farms that were responsible for providing the ducklings for restocking maintain Khaki Campbell ducks and do not have the parental stock of the native duck breeds, while restocking of the Muscovy ducks and geese are carried out by the rearers themselves. There are also no prevailing breeding programmes to conserve, select, maintain and distribute the native breeds of duck and geese. Hence, it is of earnest importance to conserve the avian genetic resources before the population dwindles further.

Résumé

L'étude se rapporte à la caractérisation phénotypique de quelques espèces de canard (le canard blanc commun et le canard de coureur indien), Muscovy esquive (le noir et le blanc aux plumes et sépia aux plumes) outre deux espèces d'oies (le blanc et le marron aux plumes et blancs aux plumes) a élevé dans l'état de Bengale d'ouest (l'Inde). L'étude a été dirigée à cinq emplacements de l'état et compris de 1395 canards et 600 oies. Les données ont été statistiquement analysées utilisant la statistique descriptive, les différences dans les moyens ont été analysées utiliser Duncan le test de Gamme Multiple. Traits qualitatifs et quantitatifs ont été considérés dans l'étude. Le trait qualitatif était la couleur de jambe, la couleur de facture, la couleur des plumes, la couleur de peau, pousser la couleur de coquille, la présence ou l'absence de haricots, la calèche de corps, facturent le type et la couleur des yeux, pendant que les traits quantitatifs inclus dans l'étude étaient le poids des canards et le poids des oeufs. Quelques traits de production à savoir. les nombres d'oeufs posé par an et habiller le pourcentage des canards et les jars de chaque espèce a été aussi étudié. Les canards et les oies sont élevés le système de direction en dessous à demi intensif et dépendent surtout de récupérer pour leurs besoins nutritifs. Ceci a pour résultat la production pauvre d'oeuf et à la perte de temps de du stock en raison des maladies. L'étude quant à la production d'oeuf de moyenne indique que le canard de Muscovy et les oies ont la production d'oeuf pauvre où comme le coureur indien suivi par le canard blanc commun est potentiellement le meilleur. Les canards sont la source importante de gains pour les petits agriculteurs de support et sont élevés pour la viande et les oeufs pendant que les oies sont surtout élevées pour le but décoratif. Toutefois, les populations des canards diminuent rapidement en raison de la grippe d'avian dans la région et que le regarnir est surtout exécuté avec les canards de Campbell de moins de Kaki adapté. Ceci a été principalement exécuté parce que les fermes de gouvernement qui étaient responsables de fournir les canetons pour regarnir maintiennent les canards de Campbell de Kaki et n'ont pas le stock parental des espèces de canard natales en regarnissant pour les canards de Muscovy et les oies sont exécuté par le rearers se. Il n'y a pas aussi prévaloir élève des programmes pour préserver, choisit, maintient et distribuer les espèces natales de canard et les oies. Donc; c'est d'importance sérieuse pour préserver l'avian les ressources génétiques avant que la population diminue plus ample.

Resumen

El estudio pertenece a la caracterización fenotípica de algunas castas de pato (pato blanco común y pato indio de corredor), Muscovy agacha (blanquinegro emplumado y la sepia emplumó) aparte de dos castas de gansos (blanco y marrón emplumó y blanco emplumó) crió en el estado de Bengala Occidental (India). El estudio fue realizado en cinco posiciones del estado y comprendido de 1395 patos y 600 gansos. Los datos fueron analizados utilizando estadísticamente la estadística descriptiva, las diferencias en el medio fueron analizadas utilizar prueba Múltiples de Gama de Duncan. Ambos rasgos cualitativos y cuantitativos fueron considerados en el estudio. El rasgo cualitativo fue color de zanca, color de cuenta, el color de las plumas, color de piel, incita color de esqueleto, la presencia o la ausencia de alubias, el coche del cuerpo, factura tipo y color de los ojos, mientras los rasgos cuantitativos incluidos en el estudio fueron pesos de los patos y el peso de los huevos. Algún v.gr. de rasgos de producción. números de huevos colocados por año y vestir porcentaje de los patos y gansos de cada casta también ha sido estudiado. Los patos y los gansos son levantados bajo sistema medio intensivo de gestión y dependen en su mayor parte de la barrer para sus necesidades nutricionales. Esto tiene como resultado la producción pobre de huevo y a veces pérdida de acciones debido a enfermedades. El estudio con respecto a la producción de huevo de promedio indica que el pato de Muscovy y los gansos tienen la producción pobre de huevo donde como el corredor indio seguido por el pato blanco común es potencialmente el mejor. Los patos son fuente importante de ganancias para los pequeños granjeros de poseedor y son levantados para carne y huevos mientras los gansos son criados en su mayor parte para propósito decorativo. Sin embargo, las poblaciones de los patos menguan rápidamente debido a la gripe aviar en la región y que la reabastecer es llevada a cabo en su mayor parte con patos menos adaptados de tela de uniforme Campbell. Esto fue llevado a cabo principalmente porque las granjas del gobierno que fueron responsables de proporcionar los patitos para la reabastecer mantienen que patos de tela de uniforme Campbell y no tienen las acciones paternales de las castas nativas de pato al reabastecer para los patos de Muscovy y gansos son llevados a cabo por el rearers sí mismos. No hay también prevalecer que cría programas para conservar, seleccionar, mantener y distribuir las castas nativas de pato y gansos. de ahí; es de la importancia seria de conservar los recursos genéticos aviares antes que la población mengüe adicional.
