largely through selection. The breed is native to southern England, especially to the counties of Dorset and Somerset. There are horned and polled strains of Dorsets named Dorset Horn and polled Dorset. Except for the presence or absence of horns, both are identical. In the horned strain both the rams and ewes are horned. The face, ears and legs are white in colour and practically free from wool. The ears are of medium size, thin silky and carried well forward. The nostrils, lips and skin are pink. The hooves are white. They produce a carcass of medium weight fine boned and of superior quality meat. The weight of the fleece is 2.75 to 3.25 kg and the wool is short, close fine in texture of 52 S to 58 S quality. A native ram and ewe in good condition weigh 80-110 kg and 50-80 kg respectively, the lambs weigh 18-22 kg at 4 months and 30-35 kg at 9 months of age. The breed is prolific. It is hardy and is capable of doing well under most conditions. iii) Southdown Southdown is one of the oldest breeds of sheep. The best specimens now closely approach the ideal mutton type in form. The body is compactly made and there is exceptional fullness of the hind quarters together with a smoothness of outline few specimens of other breeds equal. The body is oval or rounded on top, is wide and deep and is covered with firm flesh. The legs are short which with other features give the best specimens a symmetry that is unsurpassed. This is one of the smallest of the breeds. The native place of the breed is southdown chalk hills of Sussex in extreme south-eastern England. The face, ears and legs are mouse coloured or light brown and the skin is bright pink. The breed is polled although scurs are found sometimes on rams. The eyes are large bright and prominent and the ears are medium sizes and covered with short wool. The ewes are not too prolific with 125 to 150 lambs per 100 ewes and produce only average milk. The animals mature early. The fleece is short close, fairly dense and of fine quality. The annual greasy fleece weight is around 2.25 to 3.25 kg. Mature rams and ewes in good condition weigh around 80 to 100 kg and 55 to 70 kg respectively. The lambs weigh around 15,22 and 27 kg at 3,6 and 9 months of age. iv) Correidale The dual-purpose breed combine meat production with wool production qualities. Corriedale is the only important dual-purpose breed imported in India. This breed had its origin in New Zealand and Australia where both mutton and wool production are sought for in a single animal to satisfy the producer‘s requirements, since neither of the breeds used in developing corridale i.e. Merinos and Lincolns-met producers need and yet both had some of the things desired, the two were crossed. By interbreeding and careful selection a uniform type was established that produced a good balance of mutton and wool. These sheep were named after the correidale estate of Otage where the experimental crossbreeding was done. The animals inherited a good mutton conformation for its long wool ancestors and derived a dense fleece of good quality from its Merino percentage. Mature rams and ewes in good condition weigh 80-100 kg and 55-80 kg respectively. On an average they produce 4.5 to 5.5 kg greasy wool annually. The wool is of 56 S 58 S quality with a fibre diameter of 24.95 to 27.84µ. It is bright and soft with a good length. Corriedales are known for outstanding efficiency to produce more kg of lamb and wool per kg of body weight as compared to other range breeds. The face, ears and legs of these animals are covered with white hair, although black spots are sometimes present. Both sexes are polled although rams sometimes have horns. The ewes are fair in prolificacy and milking ability. In India Corriedales have mostly been imported from Australia. B) Indigenous i) Nellore Based on coat colour, three varieties of this breed are: ‗Palla‘ completely white or white with light brown spots on head, neck, back and legs. ‗Jodipi‘(also called Jodimpu) are white with black spots particularly around the lips, eyes and lower Jaw but also on belly and legs, and Dora are completely brown. The animals are 353
elatively tall with little hair except at brisket, withers and breech. The rams are horned but the ewes are almost always polled. The ears are long and drooping. The tail is short and thin. 86% of the animals carry wattles. nellore district and neighbouring areas of Prakasam and Ongole districts of Andhra Pradesh predominantly contain this breed population. i) Mandya (Syn. Bannur and Bandur) This breed is found in Mandya district and bordering Mysore district of Karnataka.

Ears are long, leaf-like and drooping. Tail is short and thin. A large percentage of animals carry wattles. Slightly Roman nose. Both sexes are polled. Coat is extremely coarse and hairy. The actual number of the breed is too small. There is high incidence of cryptorchidism in Mandya, possibly due to selection of animals for meaty conformation. It calls for conservation as the numbers are dwindling. Its body weight, weight gain, feed conversion efficiency and carcass yield are not very superior to most other breeds of the region. iii) Hassan This breed is localised to Hassan district of Karnataka. These are small sized animals with white body and light brown or black spots. Ears are medium-long and drooping. 39% of the males are horned, females are usually polled.
