The main predators of domestic goats are coyotes, dogs, mountain lions, foxes, eagles, and bobcats. Humans provide the most protection by keeping them in fences; however even that is not impenetrable. The main defense from predation which domestic goats have is living in herds. They can also be aggressive and will use their horns in defense.

Known Predators:

  • coyotes (Canis latrans)
  • domestic dogs (Canis lupus familiaris)
  • mountain lions (Puma concolor)
  • red fox (Vulpes vulpes)
  • bald eagles (Haliaeetus leucocephalus)

Morphology

provided by Animal Diversity Web

Because of its long history of domestication, there are many different breeds of C. hircus. Different breeds can have many different attributes. Typically, adults weigh 45 kg and be 64 cm tall. C. hircus is 1150 to 1700 mm in length. However, weight can vary between 9 and 113 kg and height can vary between 26 and 107 cm in different breeds.

Capra hircus is sexually dimorphic. Males have a beard, horns, a rank odor, and are generally larger than the females. The odor stems from sex glands. The horns are hollow, and grow either scimitar or corkscrew. The hair is generally straight, however some breeds have a wool undercoat. Coat color varies, and can be black, white, red, and brown. Color patterns include solid color, spotted, striped, blended shades, and facial stripes. The nose can be either straight or convex. European breeds have erect ears and Indian breeds do not. The LaMancha breed has no external ear. The tail is short and curved upward.

The average heart rate for C. hircus is 83 beats per minute, and the body temperature is 103.6 degrees F. C. hircus is born with 6 lower incisors and by 4 weeks old have a full set of milk teeth consisting of the 6 lower incisors and 24 molars. The upper jaw does not develop milk teeth, rather it has bony plates to articulate with the lower teeth.

Range mass: 9 to 113 kg.

Average mass: 45 kg.

Range length: 1150 to 1170 mm.

Other Physical Features: endothermic ; homoiothermic; bilateral symmetry

Sexual Dimorphism: male larger; ornamentation

Habitat

provided by Animal Diversity Web

Capra hircus is a domesticated animal and has been raised in almost all habitats. Goats do require grass for grazing, but can thrive in areas of thin growth that would not support other grazers such as sheep or cows. Also, C. hircus can be kept in dry lots as long as they are constantly fed by humans. Some sort of clean and ventilated shelter is necessary, but it does not have to be extravagant. For sleeping, C. hircus prefers a bedded area of at least 15 feet. Goats require exercise; optimally a goat should have at least 25 square feet per animal for this. Due to a well-developed herding instinct, C. hircus prefers to be in groups of 2 or more. As a domesticated species, C. hircus is very susceptible to predation. Therefore, it is best situated in a fenced in area. Feral groups are found usually in rugged mountain country, rocky crags, and alpine meadows.

Habitat Regions: temperate ; tropical ; terrestrial

Terrestrial Biomes: taiga ; desert or dune ; savanna or grassland ; chaparral ; forest ; rainforest ; scrub forest ; mountains

Other Habitat Features: agricultural

Distribution

provided by Animal Diversity Web

Domestic goats, Capra hircus, most likely descended from C. aegagrus which is from Central Asia. Since the domestication of this species, goats have been spread all over the world by humans. C. hircus requires grass for grazing, but can survive on very thin deposits of grass. Therefore, the only areas C. hircus cannot inhabit are tundras, deserts, and aquatic habitats. There are some feral groups on Hawaii and on other islands.

Biogeographic Regions: nearctic (Introduced ); palearctic (Native ); oriental (Introduced ); ethiopian (Introduced ); neotropical (Introduced ); australian (Introduced ); oceanic islands (Introduced )

Other Geographic Terms: cosmopolitan

Trophic Strategy

provided by Animal Diversity Web

Domestic goats are ruminants and eat grasses and shrubs. Goats can choose what grasses they will eat and generally avoid grass covered in feces. In captivity they eat roughage all year round. When the season is warm they can graze, but during the winter they are fed by humans. Farmers feed males and females different quantities and different types of foods on farms.

Associations

Because goats are a domestic species and non-native throughout most of their current range, their grazing can be detrimental to natural ecosystems. Goat overgrazing can cause erosion, spread of deserts, and the disappearance of natural wildlife. This was documented in New Zealand and scientists believe grazing by goats is preventing revegetation. A feral population of C. hircus led to the extinction of many forest bird species in Hawaii and feral goat populations may most severely impact their wild cousins, other members of the genus Capra. However, in some managed grasslands, goats have been used to prevent the spread of introduced weeds.

Behavior

provided by Animal Diversity Web

Capra hircus uses the five senses of sight, hearing, smell, taste, and touch to experience the world. To communicate with each other sight, smell, and hearing are primarily used, although touch is important when males are butting heads to determine dominance status. During the mating season the males emit pheromones. Due to domestication, C. hircus has learned to interact with other species such as humans and dogs. Vocal and visual signals from humans and dogs can control where and when members of C. hircus walk, eat, and reproduce.

Communication Channels: visual ; tactile ; acoustic ; chemical

Other Communication Modes: pheromones

Perception Channels: visual ; tactile ; acoustic ; chemical

Reproduction

provided by Animal Diversity Web

Humans usually control the breeding behavior of C. hircus. Under human control C. hircus follows a polygynous reproductive system. In nature, feral groups follow this same pattern. In captivity, certain males may be chosen by humans to sire the young of several females. The females are then inseminated either directly by those males or by artificial insemination. Left to their own devices, male goats compete for rank, and the highest ranking males have access to mate with the females. Males fight by butting heads until one competitor surrenders. Sex glands are used to produce pheromones.

Mating System: polygynous

The breeding season for C. hircus is from late summer to early winter. The female estrus cycle is 18 days long. However, in the tropics certain breeds reproduce all year long. By manipulating the amount of light goats are exposed to during the day, the estrus cycle can be artificially induced. Twins are extremely common to this species, otherwise 1 or 3 offspring is the typical brood size. Gestation differs between breeds, but is between 145 and 152 days. The young are born precocious and able to walk and follow the mother just hours after birth. About 10 months after birth the young are weaned from their mother’s milk and graze independently. Females become reproductively mature around the age of 1 year, whereas males reach reproductive maturity around 5 months of age.

Breeding interval: C. hircus breeds every 18 months from late summer to early winter.

Breeding season: Copulation occurs from late summer to early winter.

Range number of offspring: 1 to 3.

Average number of offspring: 1.25.

Range gestation period: 4.83 to 5.07 months.

Average gestation period: 5 months.

Range weaning age: 4 to 5 months.

Average time to independence: 10 months.

Average age at sexual or reproductive maturity (female): 1 years.

Range age at sexual or reproductive maturity (male): 3 to 10 months.

Average age at sexual or reproductive maturity (male): 5 months.

Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; induced ovulation ; fertilization ; viviparous

Average birth mass: 2250 g.

Average number of offspring: 1.5.

Average age at sexual or reproductive maturity (female)
Sex: female:
406 days.

Mothers of C. hircus nurse their young for 10 months after birth. The main source of parental care is the mother. She provides milk for the young. Since this is a grazing species grass is readily availiable to the young and no solid food needs to be delivered by a parent. Once the young are grown, they will remain in the herd and compete for rank.

Parental Investment: no parental involvement; altricial ; female parental care ; pre-fertilization (Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); post-independence association with parents

Brief Summary

provided by EOL authors

The Domestic Goat (Capra hircus or C. aegagrus hirca) was derived from the Wild Goat (C. aegagrus). At the beginning of this century, the United Nations Food and Agriculture Organization compiled a summary of domestic breeds of mammals and identified nearly 600 Domestic Goat breeds. The Wild Goat was likely domesticated around 10,000-11,000 years agomainly in eastern Anatolia (in modern day Turkey) and secondarily in the Central Iranian Plateau and Southern Zagros Mountains. Large-scale studies of mitochondrial DNA have indicated that all haplotypes now found in domestic goats are present in Wild Goats and more than 90% of domestic goats share the same haplotype (a haplotype that is common today in Wild Goats in the eastern Anatolia region of Turkey). Today there are an estimated 700 million domestic goats, perhaps 20% of them on the Indian subcontinent.

Goat Behaviour

provided by EOL authors

Goats are extremely curious and intelligent. Goats are easily house trained and you can teach them to pull carts and walk on leads. Goats are also known for escaping their pens. If you have unsecured fencing, be warned your goats will be inquisitive and test it out and soon you will know where the gaps are. Goats are very coordinated and can climb and hold their balance in the most awkward places. Goats are also widely known for their ability to climb trees, although the tree generally has to be at a slight angle.

If goats are raised correctly and disciplined from an early age, they never develop any bad habits. Goats will butt each other, this is quite natural and normal as they develop an order of dominance in the herd. However if corrected from an early age they never butt humans or other animals.

A goat that has been teased may butt people as part of their ‘play’, which may start as kids, when it is no problem. It can be a problem if this behaviour extends to adult age and size. Hence start correctly: if a small kid pushes against your legs, never push back.

Goats make a bleating sound much like a sheep. All in all, goats make wonderful companions and pets. Goats are a pleasure to keep and give you many hours of fun watching them with their humourous ways. Goats all have very different personalities and different little habits which can be very interesting to observe.
