What is Nutrient supplements?
- Protein (e.g. protein powder)
- Fish oil (contains omega-3 fatty acids such as DHA)
- Various vitamins (such as vitamin A, B vitamins, vitamin C, vitamin D, vitamin E, etc.)
- Minerals (e.g. calcium, iron, zinc, selenium, etc.)
- Dietary fiber
- Other specific nutrients, such as Amino Acids, enzymes, probiotics, plant extracts, etc
The purpose of nutritional supplements is to meet the nutritional deficiencies that individuals may have due to special needs, dietary habits, digestive and absorption problems, health conditions (such as disease, pregnancy, aging, etc.) or other reasons. They are usually available in the form of tablets, capsules, oral liquids, powders, etc.
When choosing a nutritional supplement, one should consider an individual's physical condition, diet, and possible side effects. Although nutritional supplements can provide additional nutrients, it does not mean that they are a substitute for a balanced diet. The best strategy is usually to get most of your nutrients through a varied diet and use nutritional supplements when necessary under the guidance of a medical or professional. In addition, excessive consumption of certain nutritional supplements may also pose health risks, so it is recommended to consult a professional before use.
Laying chicken breeding points
The natural mating behavior of chickens involves both roosters and hens engaging in reproductive activities during their breeding season. During this time, the male's reproductive system is fully developed, with the vas deferens ending in a cloacal mucosa that can swell with lymph and become slightly erect. When a rooster mates with a hen, he deposits semen onto the hen’s cloaca, which then travels through the oviduct. As the sperm moves upward, it reaches the infundibulum, where it may meet an egg cell if one is present.
If no eggs are in the fallopian tubes, the sperm can travel unimpeded, reaching the infundibulum within about 30 minutes. Once there, the sperm can remain viable for several hours, waiting to fertilize an egg. Hens typically produce fertilized eggs approximately 20 hours after mating with a rooster. In a flock, the highest fertilization rates usually occur around three days after the breeding period begins. However, once roosters and hens are separated, the percentage of fertilized eggs gradually declines, with the rate of decline increasing after five days.
In terms of sexual maturity, primary spermatocytes appear in the testes of roosters at 6 weeks of age, secondary spermatocytes develop by 10 weeks, and by 12 weeks, they begin dividing into sperm cells. By 20 weeks, the rooster is sexually mature. Mating at 22 weeks generally results in higher fertilization rates. If roosters and hens are mated too early, the fertilization success tends to be lower. Fertilization is most effective when both the rooster and hen are in their peak reproductive phase.
Roosters can be used for breeding starting at 22 weeks of age and can remain productive until 72 weeks. Their fertility does not significantly decrease over time, and they can be used for up to three years. Hens, on the other hand, should start breeding at 26 weeks and can be kept in production for up to 48 weeks. During this period, their fertilization rate can exceed 86.3%. High-quality hens can continue to lay fertile eggs for two to three years.
The ratio of roosters to hens plays a crucial role in determining egg fertility. Larger, older roosters should be paired with fewer hens, while lighter, healthier roosters in peak condition can mate with more hens. Seasonal adjustments also matter—fewer hens are needed in summer, while more can be added in autumn, winter, and spring. A general guideline is 1 rooster per 12–15 light-layer hens, and 1 rooster per 10–12 heavy-layer hens.
Hens tend to lay the most eggs between 9 a.m. and 1 p.m., with a drop in egg production in the afternoon. The peak mating activity occurs after most hens have laid their eggs, typically between 4 p.m. and 6 p.m. This timing helps ensure that the majority of hens are available for mating when the rooster is active, increasing the chances of successful fertilization.
