Summary

The Banni buffaloes distributed in the Kachchh region of Gujarat state in western India are medium to large in body size with a compact body and typical coiled horns. Mean body length, heart girth and height at withers estimated during the survey were 153.7±0.4 cm, 205.5±0.6 cm and 136.7±0.2 cm, respectively. Data on 397 adult milking buffaloes from Banni area based on interviews with farmers, revealed the mean age at first calving to be 39.7±0.4 months, a mean service period of 66.4±1.3 days, a mean lactation length of 293.3±1.5 days and a mean peak yield of 15.7±0.1 litres. Genetic diversity analysis of Banni buffaloes using a set of 15 heterologus bovine microsatellite markers revealed a high degree of allelic polymorphism with a total of 81 alleles and a mean of 5.4. The observed heterozygosity was found to be moderate with a mean of 0.506 and ranged from 0.125 (ILSTS 045) to 0.795 (ILSTS 008). The mean F value (0.181) across 15 microsatellite loci was significantly positive indicating heterozygote deficiency in the population. The test for Hardy-Weinberg equilibrium revealed seven of the 15 microsatellite loci analyzed showing significant deviations.

Résumé

Les buffles de Banni ont distribué dans la région de Kachchh d'état de Gujarat dans Inde de l'ouest sont moyen à grand dans la taille de corps avec le corps compact et les cornes embobinées typiques. La longueur de corps, la circonférence de coeur et la hauteur moyens à se rabougrit estimé pendant l'étude étaient 153,7±0,4 cm, 205,5±0,6 cm et 136,7±0,2 cm respectivement. Les données sur 397 buffles de milking adultes du secteur de Banni ont basé l'entretien de fermiers, révélés signifier que l'âge vêlant au début pour être 39,7±0,4 mois, signifier la période de service de 66.4±1,3 jours, la longueur de lactation moyenne de 293,3±1,5 jours et signifie le rendement de sommet de 15,7±0.1litres. L'analyse génétique de diversité de buffles de Banni utilisant une série de 15 heterologus les bornes de microsatellite bovines ont révélé un haut degré de polymorphisme d'allelic avec un total de 81 alleles et un moyens de 5,4. Le heterozygosity observé a été trouvé pour être modéré avec un moyens de 0,506 et étendant de 0,125 (ILSTS 045) à 0,795 (ILSTS 008). La valeur moyenne de FIS (0,181) à travers 15 lieux de microsatellite était indiquer le manque de heterozygote significativement positif dans la population. Le test pour l'équilibre de Hardy-Weinberg a révélé sept des 15 lieux de microsatellite ont analysé montrant des déviations significatives.

Resumen

Los búfalos de Banni se distribuyen en la región de Kachchh, en el Estado de Gujarat en el oeste de la India. Son de tamaño medio-grande, cuerpo compacto y cuernos típico enroscados. La largura del cuerpo, la circunferencia del torax y la altura media durante el estudio fueron de 153,7±0,4 cm; 205,5±0,6 cm y 136,7±0,2 cm, respectivamente. Los datos sobre 397 búfalos de leche de la zona de Banni se basan sobre encuestas a los ganaderos y muestran una media de edad al primo parto de 39,7±0,4 meses, un periodo medio de monta de 66,4±1,3 días, una media de lactación de 293,3±1,5 días y una producción media de 15,7±0,1 litros. Los análisis sobre diversidad Hardy Weinberg de equilibrio muestra siete de los 15 loci microsatelitares analizados con desviaciones significativas.
