When do boer goats come in heat
This is a fairly unreliable method when used alone, but can be helpful if used along with other approaches. For extended natural breeding or accelerated breeding, sexually mature does and bucks should be housed separately and exposed to at least 18 hours of light for a period of 40 to 50 days.
Dark periods must be completely dark, with no natural or artificial light even a very small amount of light can disrupt this program and prevent goats from cycling on schedule. After this period, daylight exposure is shortened to ten hours of light per day for forty days. This mimics shorter days and causes does and bucks to begin cycling. This program can increase energy bills and may require management changes to create buck housing out of sight and smell of does as well as reduce light entering goat housing from artificial light outside such as security lighting during the dark period and to prevent goats from accessing dark areas during the light period.
Hormones can be used to bring does into heat as well. Hormones are used to replicate the natural cycle of the doe. Caution: hormones are not approved for use in goats. Always consult your herd veterinarian before use. It is important to remember that hormones are used off-label for goats, so producers must have a prescription from the herd veterinarian in order to use these protocols [1].
As the products are off-label, milk and meat withdrawals are not known for many of these products. Your herd veterinarian can determine safe withdrawal times as well as correct dosages and protocols for your herd.
The breeding strategy that works best for you and your herd will depend on many factors, including market demands, management system, preferred kidding period, and willingness to invest time and money in reproductive technologies. Your herd veterinarian is an essential component to establishing successful breeding program. Always consult your veterinarian when considering a new breeding strategy.

The genetic makeup of the animal also determines when puberty occurs in the female. Puberty is reached when the female exhibits her first heat estrus and ovulation. Estrus, or heat, is the period in which the doe will stand and allow the buck to breed her.
This phase of the reproductive cycle may last between 12 to 36 hours. The period from one heat cycle to the next is referred to as the estrous cycle. In goats, the estrous cycle occurs every 18 to 24 days, or 21 days on average.
Does that are in heat may exhibit signs of mucous discharge from the vulva, swollen vulva, bleating, frequent tail wagging, pacing down the fence line and standing in heat. If the herd is checked twice a day, marked females can then be separated and mated to the appropriate stud male.
The duration of estrus varies from 12 to as long as 48 hours. Within that duration standing heat the period the doe stands firmly when a buck attempts to mount lasts approximately 24 hours. For some unknown reasons, some does in estrus will not stand to be bred by certain bucks. Ovulation usually occurs 12 to 36 hours from the onset of standing heat. At the beginning of estrus, the vaginal discharge is clear and colorless. It becomes progressively whiter and more opaque towards the end of standing heat.
Does reach puberty and may be ready to breed at 7 to 10 months of age. Therefore, in deciding when to breed does, producers should consider their age and size, but also when they were bred last, and their body condition. Season should also be taken into consideration because kids born during the hot spring or summer months do not thrive and experience more health problems than kids born during cooler parts of the year.
Meat goats are often bred every 8 months. Such frequent breeding requires excellent management, good nutrition, and breeds that effectively breed out of season. However, breeding once a year will result in increased litter size per breeding and over the lifetime of the doe, give the doe more time to nurse kids when they grow the fastest, and will give the doe time to rest to replenish its body condition for the next breeding season.
