An Overview Of Artificial Insemination for Boer Goat Breeders

What Is Artificial Insemination for Boer Goats?

Boer and Angora goats have an estrous cycle and can be artificially inseminated with a coconut water-based diluent. Although this method is not recommended for all goats, it is widely used in some countries. The main drawback of artificial vaginalization is its lack of reproducibility. It can also damage sperm motility and require anesthesia. In Sweden, however, the practice is legal.

Do Angora or Boer Goats Have Estrous Cycles?

The estrous cycle is an important part of the reproductive activity in goats. The goat’s ovarian system undergoes a series of changes during its estrous cycle, which lasts about 21 days. During this period, the ovaries undergo a series of physiological, biochemical, endocrine regulation, and morphological changes. The follicular wave occurs during this time and is characterized by a series of gonadotropin-dependent events.
Angora goats’ estrous cycles differ from those of sheep. In contrast to sheep, ewes of Angora goats’ estrus periods occur only once per year, lasting anywhere from 19 to 21 days. During this time, they are receptive to buck’s attention and may become pregnant.
Angora and Boer goats’ estrous cycles differ from that of other goat breeds. The cycle lengths can vary from 17 to 25 days, although a 19-day cycle is a norm. It is extremely helpful to track the cycles of your goats so that you can breed them successfully. While goats do not usually make much noise, when they are in heat, they will scream and wag their tails.
Synchronization of estrus in goats can be achieved outside and within breeding seasons by utilizing artificial insemination. Estrus synchronization may also be accomplished using light hours, male effects, or hormones. Nonetheless, the use of artificial insemination is limited throughout the world, primarily due to the lack of resources and trained technicians.
Angora goats are very profitable and can produce five to 10 pounds of mohair twice a year. Younger goats yield the highest quality mohair, while older goats produce the coarsest. They can be used for a variety of uses, including clothing.
Unlike sheep, angora and Boer goats’ estrous cycles differ from sheep’s. The angora ewes, for example, do not exhibit silent heat until a ram is introduced to the herd. After introducing a ram, angora ewes ovulate 16-17 days later.
Angora and Boer goats undergo an estrous cycle in the spring. The duration of their standing estrus varies depending on age, breed, and season. During the breeding season, the period can last as little as four hours or as long as 48 hours. After breeding, the goats require additional care, including feeding extra protein and maintaining a clean water environment.
When they are introduced to males, the females respond to the male’s scent and complete contact. Unlike sheep, goats do not require complete shearing of the male. The presence of a buck increases the secretion of luteinizing hormone, which stimulates folliculogenesis and ovulation.
The natural timing of mating corresponds with good natural grazing. Natural grazing will normally satisfy the feeding requirements of a “dry” ewe. Stimulatory feeding, however, can increase conception figures and eventually kidding percentages. Its effect is greatest in young two-tooth ewes. The effects will be most dramatic during the first mating.

Can Boer Goats Be Artificially Inseminated?

One of the easiest ways to breed genetically pure Boer goats is through artificial insemination. This method involves a breeding stand with facilities for restraining the doe and a sterile insemination gun. Both disposable and metallic guns are available. To ensure sterility, the gun should produce minimum heat and use a sterile light source.
Boer goats are naturally ovulated, but artificial insemination increases breeding efficiency. The process requires a high estrus response in the females. Despite the potential benefits, artificial insemination does not guarantee high pregnancy rates. However, it can improve the breeding output of your goats and improve economic profitability.
A successful artificial insemination procedure requires quality semen. The quality of semen is dependent on its collection, extension, and storage. There are several ways to collect semen in goats, including the use of an electro ejaculator. The electro ejaculator stimulates the ampullae, which then stimulates erection and ejaculation. Once the semen is collected, it should be tested for mass motility, individual progressive motility, volume, and quality.
In some countries, this method is used. Although it is not widely used, it was considered the least effective method for reproducibility. It affects sperm motility and requires anesthesia. However, this method is permitted in Sweden under the proper permission. So, if you’re planning to artificially inseminate your goats, remember to follow these tips.
If you’re planning on artificially inseminating Boer goats, there are several steps you need to follow. First, you must carefully evaluate your buck. A poor buck may have undesirable traits and will spread throughout the population. Second, you’ll have to select the appropriate does to mate with the performance-tested ram.
Third, keep meticulous records of reproductive cycles and treatments. A good record will reveal whether or not your goat has a normal cycle. Record when she’s ovulating, when she’s having follicle growth and when she’s in her proestrus. The mature egg is surrounded by a fluid-filled sac on the outside of the ovary, which looks like a blister on the skin. The blood estrogen level rises during this time.
Artificial insemination can be a hit-or-miss process. To be successful, your producer needs to have a good heat detection program. This helps the technician time the insemination correctly to coincide with the time the female ovulates. Other tips include thawing the semen before the female is restrained.
Artificial insemination is an easy procedure, but it’s important to choose a method that’s safe and reliable. The specula can be sterilized with boiling or air-drying. You should use sterile gloves when using the specula. A good idea is to purchase disposable plastic-type specula from mail-order companies to avoid the risk of infection.
The donor goat should be at least two years old and have a clean pedigree. This will help you determine if any genetic disorders have occurred in the family. A donor goat should also have a clean background record, containing no medical issues. Lastly, a donor goat should be examined visually for signs of disease, infections, parasites, and injuries.

Can Boer Goats be Artificially Inseminated With Diluent?

Coconut water-based diluent is an excellent way to preserve the quality of the liquid semen. This method allows liquid semen to be stored at 4 to 5oC and maintain its quality over time. A recent study confirmed the feasibility of using coconut water as a diluent. The research team used a Boer buck that was three years old and 30 does to be the acceptor. They also compared coconut water with a control diluent (Tris-aminomethane with 10% egg yolk) to determine the success rate of insemination.
The cases were presented to the University of Missouri Veterinary Teaching Hospital. Three of the animals had blepharospasm, euryblepharon, and entropion, while two had a deep stromal corneal ulcer. All the affected eyelids were surgically removed at MU-VMTH, and the animals recovered after undergoing surgery.
Boer goats can be artificially inbred in a laboratory using a coconut water-based diluent. This method has a low mortality rate, and the results are consistent. The process is more effective than conventional methods of insemination.
The gestation period of a Boer goat is 148.2 +/-3.7 days. Multiple births do not affect gestational length significantly. Moreover, the uterus is almost fully involuted by day 28 post-partum. During this period, the post-partum anoestrous period lasts 55.5 +/ 24.9 days. Therefore, the mean interval from partus to conception is 62.0 +/ 20.2 days.
In recent studies, Boer goats can be artificially inseminated with a coconut water-based diluent. However, there are a few caveats to this technique. It is important to note that the procedure is not a permanent solution and requires anesthesia.
A small amount of selenium (Se) in the diet did not affect the quality of the sperm. The sperm of control bucks had more abnormal mitochondria than those of Se-supplemented bucks. In addition, nano-Se supplementation increased testicular Se content and GSH-Px activity. It also preserved the tight array of mitochondrial membranes.
The study was not conclusive due to the small number of animals and herds in the study. Smaller herds in the study reduced the statistical power of the study to detect higher seroprevalence in C. burnetii. More research is necessary to confirm the findings and determine the public health risks posed by C. burnetii infection.
