ams) in November, 1975 for evaluation of their purebred performance as well as that of their<br />

crosses with some indigenous coarse carpet wool breeds under hot and cold-arid conditions.<br />

Out of the aforesaid 250 Karakul sheep, 27 ewes died during air transit, 50 ewes and 10<br />

rams were transferred to Khumbathang in Kargil district of J & K state to study their<br />

performance in cold arid conditions of Ladakh. Eight of the remaining 40 rams were transferred<br />

to the CSWRI main campus at Avikanagar for conducting cross-breeding trials with some<br />

native breeds of sheep.<br />

The geographical location of Bikaner is at 28 o 3' N latitude and 73 o 5' E longitude at 244.84<br />

meters MSL with an annual average rainfall of 281.15 mm. The farm area is undulating having<br />

ranges of sand dunes covering approximately 25% of the total land surface. The soil is sandy<br />

with about 90% sand. The growth,survivability and reproductive performance of Karakul sheep<br />

at the Division of Carpet Wool and Karakul Pelt Production at Bikaner over the years are<br />

presented in Tables 12.1 to 12.6. The studies indicated for very good adaptability of Karakuls<br />

to hot arid conditions. Their tupping and lambing percentages were quite satisfactory and so<br />

were pelts of the lambs born in India well comparable to those born in former USSR.<br />

The geographical location of Khumbathang is at 34°.10 N latitude and 77°.40 E longitude.<br />

The total strength at the end of April,1977 at <strong>Sheep</strong> Breeding Farm, Khumbathang was 10<br />

rams, 50 ewes, 25 male and 29 female lambs. The growth, survivablity, wool yield and<br />

reproductive performance of Karakul sheep at Khumbathang presented in Tables 12.7 to 12.10<br />

revealed satisfactory performance of these sheep in the cold arid region.<br />

Five Karakul rams were tranferred in 1976 from the Division of Carpet Wool and Karakul<br />

Pelt Production, Bikaner to main campus at Avikanagar to conduct a small trial on crossing of<br />

Karakul with native carpet wool breeds, viz. Chokla, Nali, Malpura and Sonadi during<br />

February-March, 1976 breeding season. As per the results, the Karakuls combined well with<br />

the coarse carpet wool breeds (Malpura and Sonadi) as the crosses with Chokla and Nali were<br />

much inferior in pelt quality as compared to the crosses with Malpura and Sonadi. A research<br />

component ―Exploratory trials on crossbreeding Karakul with indigenous coarse carpet wool<br />

breeds‖ was included as a regular activity of CSWRI. Three such breeding trials were<br />

conducted from 1977-79 to confirm the earlier results. As such, the Malpura and Sonadi ewes<br />

available under mutton component of the AICRP on sheep breeding at CSWRI, Avikanagar<br />

were bred to Karakul rams during their last breeding season‘s oestrus cycle every year. The<br />

relative performance of resultant halfbred crosses was compared with their purebred natives<br />

produced under the mutton component in a routine manner. During the year 1978, 5 more<br />

Karakul rams were added, two out of the previously transferred had died due to specific<br />

diseases. For number of Malpura and Sonadi put to each trial being small, the results on pelt<br />

quality (using the same standards as for Karakul pelts) of the two coarse carpet wool breeds,<br />

viz. Malpura and Sonadi and their halfbreds with Karakul were pooled and are presented in<br />

Table 12.11.<br />

It was seen that of the two native breeds, Malpura lambs produced better pelts as<br />

compared to Sonadi. While the ornament in the native breeds was restricted to only<br />

part of the skin, it was spread over whole of the skin in Karakuls. For Malpura, 5.00,<br />

40.00, 28.33 and 2.50% pelts were of jacket, ribbed, flat and caucassion types as<br />

compared to 1.31, 14.47, 23.68 and 2.62% respectively in Sonadi. Although in general<br />

the halfbreds produced better types of pelts than their purebred native contemporaries,<br />

the Sonadi Karakul halfbreds produced even better types of pelts than the Malpura<br />

halfbreds. The jacket type pelts increased from 1.31% in Sonadi to 42.64% in Karakul<br />

x Sonadi halfbreds, whereas in the Malpura halfbreds, the jacket type pelts were<br />

29.78% as against 5% in Malpura. There was also a decrease in average fibre length in<br />

halfbreds. The spread of ornament increased almost all over the skin and was quite<br />

comparable to the Karakul pelts. There was also improvement in lusture of halfbreds.<br />

The colour varied from patches of black or sur to complete black or sur, offering a<br />

future potential for number of colour lines.<br />
