Distributed widely throughout Mongolia are various breeds of local fat-tailed carpet-wool sheep. Totalling nearly 14 million, the sheep of Mongolia are well equipped to withstand low temperatures, unfavourable ecological conditions and poor vegetation. Grazing takes place on year-round pastures with no supplementary feeding, while improvement has been achieved by crossing with exotic, fine and semi-fine wool sheep breeds. This article describes 15 of these indigenous breeds.

Situated in the heart of Asia, Mongolia covers an estimated total area of 1565000 km². The distance between the western and eastern borders is 2405 km, and 1260 km between the northern and southern borders. The total length of the national border is 7678 km, of which 3005 km form a common border with the USSR in the north, and 4673 km with China in the south.

Ecology

Mongolia's topography is generally mountainous and interspersed with broad areas of plains. The highest mountain is Mount Munk Kharhan at 4362 m and the lowest area is the basin of Lake Khkhu Nur at an altitude of 552 m.

In the north, the virgin forests of the taiga cover approximately 8 percent of the whole territory of Mongolia. Eighty-eight percent of the country is good pasture land and is well watered by numerous rivers and lakes. In the south, the steppe changes into desert steppe and scrubland, and then into the semi-desert of the Gobi. Less than 1 percent of Mongolia is sandy desert.

The climate of Mongolia is continental, with four distinct seasons: spring, which is variable and windy; a hot dry summer with temperatures normally rising to 25 to 30°C; a cool autumn; and a cold winter with heavy snowfalls and temperatures as low as -30°C. The temperature in summer may sometimes reach 42°C, while in winter it may fall as low as -52°C. Average annual precipitation is 200 to 300 mm. In the Khangai Mountains precipitation can reach 400 to 450 mm, but in some places in the Gobi it amounts to only 60 to 100 mm a year.

Indigenous sheep breeds

Widely distributed throughout the country are a number of outstanding local breeds of sheep. They are fat-tailed carpet wool breeds and admirably adapted to cold environments. These different breeds of sheep undoubtedly constitute a valuable, although little-known, component of the animal genetic resources of the world. The estimated total number of sheep at the end of 1987 was 13.6 million, made up of many indigenous breeds, 15 of which are described in this article.

These breeds are located in different climatic belts and at varying altitudes in the mountains, hills, plains and sandy deserts of the country.

Sheep in Mongolia may be grouped into five types. The common native sheep are multipurpose and low in productivity. The other four are used more specifically for their meat (mutton), carpet wool, milk and good-quality lambskins. Grazing is on year-round pastures with no supplementary feeding, even under severe winter and spring conditions. The sheep are well adapted to the unfavourable ecological conditions of steep mountains and poor vegetation.

One distinctive feature of the native coarse wool fat-tailed sheep is noticeable when new grass grows on the pasture: at this time they grow rapidly, are easy to fatten and have a remarkable ability to store 4 to 6 kg of fat around the kidneys, mesentery and the tail bone. This fat is drawn on in winter and spring.

Sheep are reared according to the natural and economic conditions of the different regions in the country. Improvement achieved by crossing exotic, fine and semifine wool sheep breeds has been rapid in Mongolia and the results reasonably good. The average fleece weight of improved (cross-bred) fine and semi-fine wool sheep is two or three times higher than that of the native coarse wool of fat-tailed sheep. Wool quality has also improved.

There are five distinct sheep breeding zones:

· the northern mountain and grassland zone;
· the central steppe zone;
· the southern semi-arid zone;
· the southernmost, semi-desert zone of the Gobi;
· the Altay Mountains in the west.

The northern mountain grassland zone and the central steppe zone are given over to the breeding of fine and semi-fine wool sheep. In the southern semi-arid zone and the northern enclave, Mongolian fat-tailed sheep are purebred. Selection of breeding stock increases the quantity and improves the quality of the carpet wool.

In the extreme south, the semi-desert area of the Gobi has been allocated to Karakul breeding for lambskins. The production of mutton, fat and carpet wool takes place in the western part of the country and includes the Altay Mountains.

Baidrag

The name is derived from the location of the breed beyond the river Baidrag in the province of Bayan Khongor. The sheep are mainly raised in the mountainous region of Khangai at altitudes between 2000 and 4000 m. The average flock size is 500, but can range from 400 to 800.

The colour of the breed, which is used mostly for meat and wool, is white while the head and legs of most animals are black or brown. Average liveweight at birth is 3.7 kg for males and 3.5 kg for females; while the average adult liveweight for the ram and ewe is 65 kg and 53 kg, respectively.

Breed characteristics are a compact medium-sized body with a round back and straight belly. The head is small; the quarters are moderately developed with thin, medium legs; and the breed belongs to the small fat-tailed, long carpet wool type. The horn-setting of rams is typically spiral. They have tapering cone-shaped tails which reach the points of the hocks. Body measurements are given in Table 1.

First breeding occurs at the age of about 18 months and the breeding interval is one year. Usually, single lambs are born. The main breeding season is autumn and mating continues for two months. The breeding age for both rams and ewes lasts from six to eight years.

The dressing percentage of this breed is 47.7 and the mutton quality is juicy and good. Milk production amounts to 300 g day.

The wool of these sheep is relatively fine and, because of its elasticity and lustre, it makes good carpets. Wool characteristics are given in Table 2.

Bajad

This breed is reared in Malchin, Khirgas and the East Gobi districts of Obsnuur province, but since 1967 sheep of this breed have been reared in many other provinces as well. Flock size is from 500 to 600. The breed is reared for its meat, wool and milk. Liveweights at birth are 3.8 kg for males and 3.5 kg for females. Adult liveweight is 72 kg for rams and 56 kg for ewes. The colour of the body is white but the head, face and neck may be white or fawn with black or brown rings around the base of the eyes.

Breed characteristics are a compact body with a straight, broad round back, well-developed hindquarters and broad loins. The head is of medium size with a slightly Roman nose and wide nostrils. The neck is strong and well developed with fleshy shoulders. Weighing 2 to 4 kg, the fat-tail is thick, broader at the base and reaching down to the hocks. Rams are occasionally horned and 47 percent of ewes have horns.

Age at first lambing is between 15 and 18 months and breeding is generally allowed in September to October. Males and females are used for breeding for six to seven years. Ewes usually lamb once a year and twins are rare. Rams are generally selected for breeding on the basis of body weight and conformation. Body measurements are given in Table 3.

The quality of the mutton is very good, with the fat-tail also being important. The dressing percentage is 45.4 and milk production from 200 to 800 g per day. Wool characteristics of the Bajad are given in Table 4.

Barga

The Barga sheep are found in the Khuleng Boir district of the Eastern Aimak province. Average flock size is 800 with a range from 600 to 2000. The Barga are used mostly for meat and wool. Liveweights at birth are 3.5 kg and 3.2 kg for males and females, respectively. The average adult liveweight of rams is 70 kg and that of ewes 50 kg. The colour of the body is white while the head is generally tan or brown- or black-spotted. The neck and legs are white but may sometimes be black- or brown-spotted on the knees and hocks.

The flocks are pure-bred and the age at first breeding is 18 months. Generally, lambs are born singly and are allowed to suckle until ewes are dry. The breeding season is from September to October. The breeding age lasts from six to seven years for ewes and a little longer for rams. Males that are Unsuitable for reproduction are castrated at 1.5 to two months of age and rams are selected for breeding on the basis of body size and fleece weight. Body measurements are given in Table 13. The dressing percentage of this breed is from 41.1 to 47.6 and mutton quality is good. Milk production amounts to 200 to 600 g daily in lactations of 60 days. Wool characteristics are given in Table 14.

Khalkha

This Mongolian fat-tailed sheep is an important breed not only in terms of its wide distribution in Mongolia, itself, but also because it was the original "gene pool" for several other breeds which are now domesticated in different parts of the world. Flock sizes are from 500 to 1200 and the breed is kept mainly for meat, wool and milk.

The liveweight of the Khalkha tends to vary seasonally and according to location. In the pastoral areas, the mean liveweight for adult rams is from 65 to 75 kg, and from 50 to 60 kg for ewes. The colour of the body is usually white, and the head coloured. The breed is normally covered with coarse wool and is known locally as the "black-headed" sheep, although some animals do not- possess this characteristic. A black head is favoured by the sheep breeders since they are much easier to spot than white heads in the snow-covered areas. Thus, it probably gives the animal some advantage in selection for breeding. The predominant pattern is white with a coloured head, although different types of piebald and occasionally self-coloured animals are found.

Characteristics of this medium-sized breed are a compact body with a straight back. The head is small- to medium-sized with a bulging forehead. Ears are medium-sized and the neck is of a medium size and well set at the thorax. The shoulders are straight and fleshy. The belly is somewhat pendulous and covered with scanty wool. Rams have curved horns and females are polled. The fat-tail is medium-sized, weighing 1.5 to 4 kg. The legs are straight and stout and covered with short, coarse wool.

Age at first breeding is 15 to 18 months and the main breeding season is autumn, with mating continuing for 45 days. Generally, single lambs are born once a year. Male lambs not selected for breeding are castrated at two months of age and sold at the age of six months to two years. Rams and ewes are used for breeding up to six or seven years of age. Body measurements are given in Table 15. The dressing percentage is 46.5 and mutton quality is very good. Milk production is from 70 to 130 g daily. Wool characteristics are given in Table 16.

Khangai

This new finewool breed was developed in the Zagaan Nuur district of Selenga province by crossing local coarse wool native sheep with fine wool sheep breeds from the USSR; for example, Altay, Goznen and Stavropol. The Zagaan Nuur district is located in the Selenga River valley in the northern part of Mongolia. The Khangai breed was approved by the Mongolian Government in 1977.

Flock size ranges from 400 to 500 and the sheep is bred for its fine wool and meat. Liveweight at birth is 4.2 kg for males and 3.8 kg for females. Liveweight of adult rams is 80 kg and of adult ewes 58 kg.

Characteristics of the Khangai are a compact body with a straight back and slightly pendulous belly, which is covered with wool. The head is medium-sized with a straight nose and medium-sized ears. The neck is thin, long and well set at the thorax. The shoulders are straight and fleshy and the legs straight and thin. The tail (15 to 20 cm long) is also thin. All rams are horned and ewes are polled. The colour of the Khangai is completely white.

Age at first breeding is 18 months and lambs are generally born as singles. Males and females are used for breeding for six to seven years and lambing percentages vary from 110 to 130. Body measurements are given in Table 17. The dressing percentage of this new breed is 47. Its mutton quality is fair and milk production is from 300 to 700 g per day. Wool characteristics are given in Table 18.

Orhon

This semi-fine wool sheep of the central steppe zone has been developed from the F1 progeny of Mongolian fat-tailed ewes and precocious Soviet Marino or Tsigai and Altay rams, which were used on successive generations of cross-breeds. Named after the Orhon River, this breed was approved by the government in 1961.

Flock size ranges from 400 to 500 and the breed is reared for its meat, wool and skin. Average liveweight at birth is 4 kg for males and 3.6 kg for females; liveweight of the adult ram is 80 kg and of the ewe 57 kg.

The colour of the Orhon sheep is completely white. Characteristics of the breed are a compact body with a straight back, head and ears of medium size, with the latter tapering at the points. The neck is thick and strong, broader at the base and narrower toward the head. The legs are medium and stout and covered with wool; the tail is long (about 20 cm) and thin, and is cut at an early age. Eight percent of rams are horned and all females are polled.

Age at first breeding is 18 months and lambs are generally born as singles, although the twinning rate is 10 to 30 percent. Males and females are used for breeding for six to seven years. Breeding is predominantly pure and rams are selected primarily for body size and for the weight and quality of their wool. Body measurements are given in Table 19. The dressing percentage of this breed is 50 and the mutton quality is good. Milk production is about 300 g per day. Wool characteristics are given in Table 20.

Sutai

Flock size is from 500 to 550 and the breed is kept mainly for meat, wool and milk. Liveweight at birth is 3.5 kg for males and 3 kg for females. The average liveweight of adult rams is 72.5 kg and of adult ewes 57.4 kg. The body colour of the breed is white, and the head is black or brown, with black rings around the eyes.

Characteristics of the breed are a compact body with a straight back and a comparatively higher posterior. The head is medium-sized with a Roman nose. The legs are brown with dark spots and black hooves. The fat-tail is medium-sized and the ears are broad, long and drooping. Sixty percent of males and 15 percent of females are horned. Age at first breeding is from 15 to 18 months. Males and females are used for breeding for 6 to 7 years. Body measurements are given in Table 21. The dressing percentage is from 42.5 to 48.1 and the mutton quality is juicy and good. Wool characteristics are given in Table 22.

Torguud
