Short tandem repeat (STR) based genetic diversity and relationship of domestic sheep breeds with primitive wild Punjab Urial sheep (Ovis vignei punjabiensis)

Pattanam sheep differs in many aspects as compared to Ramnad white sheep, which is another popular sheep breed distributed in the same tract. The present study is carried out to collect information on Pattanam sheep for registering in the National Bureau of Animal Genetic Resources list of registered sheep breeds.

Characterization and Evaluation of Pattanam Sheep of Tamilnadu

Population structure and genetic relatedness of Sri Lankan Jaffna Local sheep with major South Indian breeds

: This study was carried out for the estimation of Body Weight (BW) of bapedi sheep from Body Length (BL), Sterna Height (SH), Heart Girth (HG), Height at Withers (WH), Rump Height (RH) and Head Length (HL). Correlation and regression were used. Correlation displayed that body weight is highly positively associated (p<0.01) with WH and HG in males while for females, correlation is highly positively associated (p<0.01) with WH, HG, and HL. Regression analysis revealed that the equation with HG was the best-fitted regression model (R 2 = 0.64, RMSE = 5.06, AIC = 77.69, BIC = 78.86) for estimating Body Weight in the Bapedi sheep males while an equation including HG, WH, R, SH and HL, was the most suitable regression model (R 2 = 0.79, RMSE = 3.72, AIC = 274.49, BIC = 287.66) for female Bapedi sheep body weight estimation. These findings suggest that HG may be chosen during selection and production for the improvement of body weight in males while HG, WH, RH, SH, and HL may be selected for the improvement of body weight in females. Therefore, outcomes may assist sheep farmers during the breeding stock selection and precisions during daily animal welfare routines such as feeding, veterinary services, and marketing.

espanolPattanam es una raza ovina de gran importancia en Tamil Nadu (India) y muy popular entre los agricultores por su elevado peso corporal. Pese a su importancia economica y su marcada identidad, esta raza no se encuentra incluida en la lista de razas ovinas descritas a nivel nacional ya que hasta el momento no habia sido estudiada. Por esta razon se realizo un estudio con el fin de documentar el habitat, la distribucion, los caracteres fisicos, los resultados de produccion y reproduccion y las practicas existentes de manejo de la oveja Pattanam de Tamil Nadu. El estudio preliminar revelo que la raza Pattanam se caracteriza por su gran tamano, un cuerpo compacto y un color blanco cremoso uniforme con color negro en la region ventral desde la parte interior de la mandibula hasta la region inguinal. Los animales de pura raza se encontraron distribuidos en las provincias de Paramakudi, Mudukulathur y Kamuthi del distrito de Ramanathapuram y las provincias Aruppukottai y Thiruchuli del distrito Virudunagar, en la zona agroclimatica mas meridional de Tamil Nadu. Las medias de longitud corporal, altura de la cruz y circunferencia del pecho observadas fueron 80,65 ± 0,49, 85,58 ± 0,58, 93,65 ± 0,35 cm en carneros adultos, y 70,05 ± 0,45, 72,80 ± 0,65 y 78,34 ± 0,35 cm en hembras adultas, respectivamente, y el peso corporal fue de 51,50 ± 1,20 y 36,95 ± 0,51 kg en machos y hembras respectivamente. La oveja Pattanam es una raza invasora cuyos machos son ampliamente utilizados para la cria con otras razas autoctonas, especialmente con Coimbatore, Kilakarsal y Ramnad White de Tamil Nadu. EnglishPattanam is an important mutton-breed sheep of Tamil Nadu, India and is popular among the farmers for its heavy body weight. Despite its economic importance and distinct identity, this breed is not included in the list of descript sheep breeds at the national level, as it is not researched so far. Hence, a study has been made to document the habitat, distribution, physical traits, production and reproduction performances and the existing management practices of Pattanam sheep of Tamil Nadu, India. The preliminary study revealed that Pattanam sheep is a large-sized breed with compact body and uniformly creamy white in colour with black colour in the ventral region from the inner side of the jowl extending up to the inguinal region. Pure breed animals were distributed in the Paramakudi, Mudukulathur and Kamuthi taluks of Ramanathapuram district and Aruppukottai and Thiruchuli taluks of Virudunagar district of southern agroclimatic zone of Tamil Nadu, India. The means of body length, height at withers and chest girth in adult rams were 80.65 ± 0.49, 85.58 ± 0.58 and 93.65 ± 0.35 cm and in adult ewes were 70.05 ± 0.45, 72.80 ± 0.65 and 78.34 ± 0.35 cm, respectively. The body weight in adult rams and ewes were 51.50 ± 1.20 and 36.95 ± 0.51 kg, respectively. Pattanam sheep are used extensively for breeding purposes with other native breeds especially from Coimbatore, Kilakarsal and Ramnad White sheep of Tamil Nadu. francaisLa race Pattanam est une importante race de moutons a viande du Tamil Nadu, en Inde, tres prisee par les agriculteurs en raison de son poids corporel considerable. Malgre son importance economique et son identite particuliere, cette race n'est pas incluse dans la liste nationale des races de moutons car, jusqu�a present, elle n'avait pas encore ete documentee. Par consequent, on a realise une etude pour decrire l'habitat, la distribution, les caracteres physiques, les performances de production et de reproduction et les pratiques existantes de gestion de cette race. L�etude preliminaire a indique que les moutons Pattanam presentent une taille considerable et un corps trapu. La couleur blanc creme est uniforme, avec du noir dans la partie abdominale, de la gorge jusqu�a la zone inguinale. Les animaux de race pure ont ete distribues dans les taluks de Paramakudi, Mudukulathur et Kamuthi du district de Ramanathapuram et dans les taluks d'Aruppukottai et Thiruchuli du district de Vurudunagar, dans la zone agroclimatique meridionale du Tamil Nadu, en Inde. Les moyennes de la longueur du corps, de la hauteur au garrot et de la circonference de la poitrine des beliers adultes sont respectivement de 80,65 ± 0,49, 85,58 ± 0,58 et 93,65 ± 0,35 cm et celles des brebis adultes sont de 70,05 ± 0,45, 72,80 ± 0,65 et 78,34 ± 0,35 cm. Les poids corporels des beliers et des brebis adultes sont respectivement de 51,50 ± 1,20 et de 36,95 ± 0,51 kg. Les moutons Pattanam sont une race envahissante dont les beliers sont largement utilises pour des objectifs de selection avec d'autres races indigenes, surtout avec les moutons Coimbatore, Kilakarsal et Ramnad White du Tamil Nadu.
