Whether it's from sleeping weird, working out too hard, or sitting hunched over for hours staring at your computer, most of us have dealt with kinks in our necks from time to time. According to a peer-reviewed article from Marco Funiciello and Zinovy Meyler, Doctors of Osteopathic Medicine, one of the best ways to soothe aches and pains in your neck is through massage therapy.

While going to a massage therapist can be a relaxing experience, it can also be quite expensive. So if you don't have the time or money to get a professional massage, investing in a portable, at-home neck massager is a cost-effective alternative. The handy gadgets can knead out tight knots and melt stress away with ease.
There are many kinds of neck massagers on the market, including portable handheld models, devices that wrap around your neck, and even manual massager rollers. Some boast special features like adjustable heating controls so you can apply heat therapy to painful spots, while others are designed to target pressure points for migraine relief.
Improve management of breeder fertility
First, the breeder's age should be appropriate. Typically, breeders between 200 to 400 days old have a higher fertilization rate. After 60 weeks of age, the quality of the rooster’s semen tends to decline, and the hen’s egg production decreases, which ultimately leads to lower fertility rates. It's important to select breeders at the optimal age to ensure successful breeding outcomes.
Second, the quality of the rooster’s semen must meet certain standards. Healthy roosters produce semen that is milky white in color and has a creamy texture. Any deviation from this—such as discoloration, presence of blood, feces, or urine, or if the semen is too clear—is considered substandard. In addition, good semen quality also includes high sperm concentration and strong sperm motility, both of which are crucial for successful fertilization.
Third, it's essential to ensure that the hen’s reproductive tract is free from disease. Some hens may lay eggs regularly but due to physiological issues or underlying health problems, their eggs may not become fertile even after artificial insemination. These infertile hens should be identified and removed from the breeding program to maintain overall fertility levels.
Fourth, proper insemination techniques are critical. The amount of semen per chicken should not exceed 0.4 ml. The best time for insemination is between 3 to 4 pm, when the hen's body is more receptive. The interval between inseminations should be 5 to 7 days; extending or shortening this interval can reduce fertility. The insemination depth should be about 1.5 cm into the oviduct. Also, the semen should be used within 30 minutes of collection, with shorter times being better for maintaining viability. Lastly, having skilled and experienced inseminators and assistants is vital for achieving consistent results.
Fifth, environmental factors play a significant role. The storage time of the eggs should not be too long—ideally 5 to 7 days in summer and 7 to 10 days in other seasons. It's advisable to avoid artificial insemination during hot summer months, as heat can negatively affect both the semen quality and the hen's ability to conceive. By considering all these factors, breeders can significantly improve the success rate of their artificial insemination programs.
