What Should Be Done for Cows to Show Estrus?
Among the most frequently asked questions by those working in the livestock sector and raising dairy cows is what should be done for cows to show estrus. Livestock breeders generally expect at least one calf per year from each cow. Therefore, they often seek answers to the question: “What should be done for cows to come into estrus?”
The display of estrus in cows is a critical factor for successful insemination and a healthy pregnancy process. In this article, we would like to support you at various stages—from understanding the signs of estrus to natural and medical interventions.
What Is the Estrus Period in Cows?
The estrus period in cows is the time when female animals are ready to mate. Estrus cycles typically repeat every 18 to 24 days. During this period, behavioral and physical changes observed in cows indicate that they are in heat.
The Physiological Process of the Estrus Period
The physiological process of the estrus period can be summarized with the following points:
Ovarian activity and hormonal balance,
Increase in estrogen levels,
Changes in the uterus and mucosal structure are related to physiological processes.
Cows naturally display signs of estrus; however, not every animal shows symptoms at the same intensity.
What Are the Signs of Estrus?
The signs of estrus, which are part of each cow’s natural cycle, are as follows:
Frequent bellowing and signs of restlessness,
Tail raising and redness around the vulva area,
Mounting behavior toward other animals,
A temporary decrease in milk yield,
Vaginal discharge indicates that your cows are in heat and ready for mating.
However, the signs may not be equally evident in every animal. Your cow might have entered estrus and shown some signs, but they could be subtle and easily missed. Especially in tied or confined cows, the outward signs of estrus can be less visible even when the cycle has started. Additionally, during the summer months, reduced activity levels or uncomfortable living conditions can prevent cows from displaying estrus behaviors clearly. For example, cows may not show estrus signs when standing on muddy ground.
How to Recognize the Signs of Estrus?
If there are no conditions preventing your cow from showing estrus, we recommend following these steps:
Observe your cow at least 5 to 6 times a day, each observation lasting about 15 minutes.
Minimize changes in the grouping of your cows. Try to keep their positions as stable as possible.
Do not change the milking schedule. Perform milking at the same time every day. Cows prefer a disciplined routine and feel more comfortable with consistency.
Avoid frequently changing your veterinarian, and unless absolutely necessary, do not allow unfamiliar people among your cows.
If, despite following all these steps, you still do not observe any signs of estrus, you can try the methods used by farmers and livestock breeders, which we will outline step by step.
What Are the Methods Used to Induce Estrus in Cows?
You can try natural methods, appropriate nutrition, supplementary additives, as well as hormone therapy and medication to help your cows enter and show signs of estrus. Before trying any of these approaches, don’t forget to consult with your veterinarian and communicate with expert teams regarding the products you use.
Supporting the Estrus Display Process with Natural Methods
You can support cows’ estrus display by enhancing their living conditions and comfort. Natural methods include:
Providing a natural light cycle,
Ensuring adequate space for movement and reducing stress,
Maintaining an ideal Body Condition Score (BCS),
Improving nutritional balance.
With our product İnteFertil, you can improve the quality of your animals’ feed, just like humans use supplements and vitamins to support their health. İnteFertil contains vitamin A and beta-carotene, which support ovarian activity, increase fertility, and enhance estrus expression. This way, it boosts your cows’ reproductive performance and fully meets their trace mineral requirements for fertility.
Hormone Therapy and Injections
Hormone therapy, medications, and injections are processes that must be carried out in consultation with a veterinarian. Under the guidance and protocols recommended by veterinarians, hormones such as Prostaglandin and GnRH can be used to induce estrus.
Care and Management During the Estrus Period
Feeding and Nutritional Needs of Cows
During estrus periods, it is essential to maintain the energy, protein, and mineral balance of your cows. Support with vitamin A, E, and selenium supplements is recommended. Irregular estrus cycles may be observed in cows that are overweight or underweight, so appropriate measures should be taken accordingly.
Social and Physical Activity of Cows
Just as nutrition is important for cows to show estrus and be comfortable during their heat periods, their social and physical activities are also crucial. The social structure of the herd affects estrus behaviors. Being tied up, restricted movement, or living in an unclean environment can negatively impact the estrus period. Therefore, it is important to provide your cows with daily access to areas where they can move and walk regularly, as well as clean, comfortable shelters free from stress.
