What is the difference between purebred and crossbred Boer goats?

Purebred Boer goats originated in South Africa and, as a breeding stock, have been introduced by many African countries as well as New Zealand, Australia, Germany, the United States, Canada and other countries. Do you know what the differences are between purebred Boer goats and crossbred goats? Let us take a look below at the differences between purebred Boer goats and crossbred goats!

The difference between purebred Boer goats and crossbred goats

1. Coat color: The coat of purebred Boer goats is fine and pure white, except that more than 80% of the head and neck is reddish-brown, and the brown is relatively deep; only the bridge of the nose is white on the head of most goats. The coat of crossbred improved goats is coarse and relatively white, and only a small part of the head and neck is reddish-brown.

2. Horn shape: The horns of purebred Boer goat rams are relatively wide and generally curve upward and backward, while the horns of ewes are small and straight. For crossbred improved goats, the horns of rams are relatively long and generally curve upward and backward, and some ewes have small horns while others are hornless.

3. Ears: The ears of purebred Boer goats are wide and long, all drooping, and reddish-brown in color. For crossbred improved goats, the ears are relatively wide and short, and generally do not droop starting from the base of the ear but droop only at 2 cm from the base of the ear, and are mostly white in color.

4. Belly shape: The belly of purebred Boer goats is relatively large, mostly shaped like a "sow" belly. For crossbred improved goats, the belly is relatively small, mostly shaped like a "cylinder" belly.

5. Hindquarters: The hindquarters of purebred Boer goats are relatively wide, with a round, full rump and well-developed muscles. The hindquarters of crossbred improved goats are inferior.

6. Legs: The four legs of purebred Boer goats are thick and short, and the hooves are mostly dark brown. The four legs of crossbred improved goats are relatively slender and long, and most hooves have no dark brown.

In addition, farmers are reminded that it is best to introduce breeding stock from large, certified farms.

Growth performance and quality of purebred Boer goats

The economic traits of goats are reflected in high-quality, high-yield livestock products, and further in the input-to-output ratio, enabling high benefits. The body height of adult purebred Boer goat rams and ewes reaches 75 cm-90 cm and 65 cm-75 cm respectively, and their body weights are 95 kg-120 kg and 65 kg-95 kg respectively. The slaughter rate is relatively high, averaging 48.3%. Boer goats can maintain production value until 10 years of age and are the world's famous goat for producing high-quality lean meat. In addition, the hide quality of Boer goats is excellent and is a superior leather raw material.

1. Reproductive capacity and lambing rate

Purebred Boer goats are non-seasonal breeding livestock and can come into estrus, mate and give birth throughout the year. Ewes mature at 6 months of age. Because sex hormone levels are relatively high in autumn, sexual activity is less in spring and summer. Autumn is the peak period of sexual activity, while sexual activity is less in spring and summer. According to the lambing results of 100 ewes, 24 gave birth to single lambs, 58 to twins, 15 to triplets, and 1 to quadruplets. The average litter size was 1.93. Rams mature at 6 months of age and, under grazing conditions, can mate with an average of 15 ewes; at over 9 months of age, they can mate with an average of 30 ewes. A high lambing rate means an increase in meat production per ewe and per unit area.

2. Roughage tolerance and adaptability

Purebred Boer goats are one of the livestock breeds with the greatest roughage tolerance and strongest adaptability. They can adapt to various climatic zones in South Africa, including inland climates, tropical and subtropical scrublands, semi-desert and desert areas, and all show good growth. Under drought conditions, without water and feed, they survive longer than other animals. They have grazing habits and can consume small trees and shrubs as well as plants that other animals do not eat. Their feeding range is large, reaching leaves and bark as high as 160 cm and forage as low as 10 cm. Therefore, they are suitable for mixed grazing with cattle to increase meat production per hectare of pasture. In addition, because Boer goats have the habit of consuming shrubs, they can be used to control shrub overgrowth and spread. Because Boer goats have the above-mentioned roughage tolerance and adaptability, they are not only suitable for raising in South Africa but also suitable for development in other countries. In our country, in addition to areas rich in forage where Boer goats can be developed, many weeds and crop straws can also be used as roughage for Boer goats, further expanding the scope of development areas.

Appearance characteristics of purebred Boer goats

1. Head

The head is solid, with large and gentle brown eyes, a firm and slightly curved nose and wide nostrils, and a well-structured mouth and jaw, which should be fully aligned at 4 teeth, protrude 6 mm after 6 teeth, and the permanent teeth should be in the appropriate anatomical position. The prominent curve of the forehead corresponds to the curvature of the nose and horns. The horns are solid, of medium length, gradually curving moderately backward, dark in color, round and hard. The ears are broad and smooth, drooping from the head, of medium length. Ears that are too short are not ideal. Characteristic defects that should be excluded: sunken forehead. Horns too straight or too flat. Pointed jaw, long and set low, short base jaw. Folded ears, protruding and short. Blue eyes.

2. Neck and forequarters

The neck is of appropriate length and proportionate to the body length. The forequarters are full and muscular. The breastbone is broad with a deep and wide chest. The shoulders are thickly muscled and proportionate to the body and withers, and the withers are broad and not pointed. The forelegs are of moderate length and proportionate to the depth of the body. The limbs are strong, the joints of the pasterns are tough, and the hooves are black. Characteristic defects that should be excluded: a neck that is too long or too short and thin, and loose shoulders.

3. Body

The ideal type should have a long, deep and broad body. The fleshy, well-sprung ribs are proportionate to the loin, the back is broad and straight, and there is no narrowing behind the shoulders. Characteristic defects that should be excluded: sunken back, poor rib spring, and a cylindrical or narrow area behind the shoulders.

4. Hindquarters

Purebred Boer goats should have a wide and long rump, and it should not be too sloping. The fleshy buttocks should not be too flat. The legs should be full and muscular. The tail is straight, grows from the tail base, and can swing to both sides. Characteristic defects that should be excluded: a rump that is too drooping or too short, and shins that are too long and can swing to both sides.

5. Limbs

The limbs are strong and well structured; those with too much muscle are not ideal. So-called strong limbs mean firm and highly adaptable, which is an important basic characteristic of Boer goats. Characteristic defects that should be excluded: X-shaped limbs and outwardly curved limbs, and limbs that are too slender or have too much meat. Weak pasterns, and hoof tips pointing outward or inward.

6. Skin and coat

Loose, soft skin with sufficient folds on the neck and chest, especially in rams, is a basic characteristic. The eyelids and hairless parts are pigmented, and the hairless skin under the tail should have a 75% pigmented area; 100% pigmentation is ideal. The hair is short and glossy. A small amount of down hair is beneficial for tolerating winter cold. Characteristic defects that should be excluded: a coat that is too long and coarse, and too much down hair.

7. Sexual organs

① Ewes: have a well-structured udder, with no more than two teats on each side.

② Rams: have two relatively large, normal, well-structured and equal-sized testicles in one scrotum. The circumference of the scrotum is not less than 25 cm. Characteristic defects that should be excluded: teats that are string-like, gourd-shaped or double teats. Small testicles, and a scrotum with a cleft greater than 5 cm.

8. Body color

The ideal type should be a white goat with a red head and ears. It has abundant pigmentation and obvious gloss, and light red to deep red is allowed. Breeding goats should have red patches of at least 10 cm in diameter on both sides of the head except for the ears, and both ears should have at least a 75% red area and the same proportion of pigmented area.
