Signs Of Heat In Goats In General livestock
The heat period in livestock is commonly termed the Estrus cycle. In the simple’s explanation, the estrus cycle/heat period is the period/time at which Doe’s/ewes will stand and allow bucks to mount and breed them. If a doe does not receive a buck to breed her in this time period, then the Estrus cycle will re-occur. The re-occurrence of the estrus cycle happens every 18-24 days, and it is extremely important that the farmer knows this time will only last for a certain amount of time, which is 18-36 hours. Due to the heat period lasting such a short time, it is therefore important for farmers to be able to identify the various Signs Of Heat that the doe/ewe displays and at this point the farmer must ensure that he/she has their breeding bucks ready to service the female within this time.
Farmers, please do note that – Estrus cycle refers to the period from one heat cycle to the next.
Signs Of Heat
I. Mucous discharge from the v***a.
II. Swollen V***a & reddened.
III. Bloating.
IV. Doe/ewe wags her tail.
V. Doe is seen to be pacing along the fence line & standing in the heat.
VI. Tail gets sticky- Vaginal discharge during heat causes hair at the tail sides to appear damp or to clamp together.
VII. Doe acts Bucky – if a doe/ewe enters their heat period in the absence of a buck, then the does will be seen to mount other doe’s. However and very importantly, I encourage farmers to monitor and observe this behavioural pattern very closely, because in some cases if this pattern lasts for more than two days, it could be an indication of the onset/oncoming of a disease rather than as a sign of heat.
VIII. Frequent Urination – Doe’s in heat have a chemical in their urine which is referred to as pheromones. These pheromones are the chemical queues that let the buck know that the doe/ewe has entered her heat period. It is during this time the doe urinates more times than normal and bucks are seen to stick their head in the urine, throw their heads back in the air and curl their upper lip (known as flehmen) in order to get a good smell of the pheromones.
IX. Buck Behavior changes – when a buck is in the presence of a doe that is in heat, his behaviour changes. Bucks are often seen to wag their tongue, stomp their front hoof on the ground, urinate on their own face and all other abnormal behaviours.
X. Doe stands for mating – This is considered to be the most significant sign of heat and also the easiest for farmers to confirm that a doe has entered heat. The doe will stand for bucks to mount and will sometimes even manoeuvre herself into position for the buck to mount/breed her.
The act of mating only lasts a few seconds, and the easiest way for a farmer to rule between what is called a ‘’Trial run’’ and actual mating is simply through the farmer observing the buck if actual mating took place the buck will arch his back during ej*******on and will also throw his head back.
I would also like to let farmers know that, some farmers are known to keep doe’s in the heat with bucks for up to two (2) months, even if her heat cycle was over. This is done with the intention of getting the doe to cycle again, and if she failed to get fertilized in the first cycle, she will surely get pregnant/settle in the next cycle.
Farmers are also encouraged to know that (day length) also has an effect on the reproduction of both bucks and doe’s.
In Bucks, the day length will affect libido (s*x drive), fertility, and semen quality and semen volume. As the photoperiod gets longer, less s***m is made and also the probability of abnormal s*x cells in the semen increases.
3. Important information on the Heat period.
i. For Successful breeding does & bucks should be joined for a period of 40-45 days, which is the length required for a doe to complete two estrus cycles.
ii. A Ratio of 20-30 does/Buck should be maintained for successful breeding results.
iii. Standing heat ( time doe stand in a position to let buck mount) will last approximately 48 hours
iv. Ovulation will occur at 12-36 hours from the onset of standing heat
v. At the beginning of standing heat, the vaginal discharge is clear and colourless, it becomes progressively clearer, whiter and more opaque towards the end of standing heat.
vi. Does reach puberty and may be ready to breed at 7-10 months of age
vii. Does/ewes should not be bred until they reach 60-75% of their expected mature body weight. This is to avoid stunted Growth and Dystocia (difficulty giving birth).
viii. Before breeding doe’s/ewes, farmers must consider AGE , Size , when they were last bred including Body Condition.
ix. I advise Farmers to carefully consider their breeding season as kids born in the hot summer & spring do not thrive well and will experience more health problems than kids born in cooler parts of the year.
x. Lastly, give the doe ample time to nurse kids that are born in seasons where they grow fastest. This will also allow the doe time to rest and to return to a good body condition score for the next breeding season.Signs Of Heat In Goats In General
