CATDOLL : CATDOLL: What should I feed hens to make them lay more eggs and bigger eggs?

Hens can increase their egg laying rate by feeding them the following:

1. Adding feather powder to feed: Adding 3%-5% feather powder to feed can reduce chicken fat, increase lean meat, and increase egg production by about 20%.

2. Feeding gypsum powder method. Feeding chickens with about 0.5-3 grams of raw gypsum powder every day can accelerate the molting of chickens that are molting and resume egg laying earlier; for chickens that are laying eggs, it can increase the egg production rate by more than 12%.

3. Zinc addition method: During the molting period of hens, add 2% zinc (such as zinc sulfate) to the feed every day for 7 consecutive days. After 1 week, the egg production rate will increase by 5%, and after 2 weeks, the egg production rate will increase by 10%.

4. Feeding fly maggots: Add 10% fly maggots to the feed and feed twice a day, morning and evening, and the egg production rate can be increased by about 20%.

5. Feeding healthy pig blood or placenta. Adding 15% healthy pig blood or pig placenta to the feed can increase the egg production rate of chickens by 20-50%.

6. Feeding small fish: Adding 20% ​​of small fish to the feed can increase the egg production rate of chickens by about 25%.

7. Feeding green vegetables: Adding 10% green vegetables to the feed can increase the egg production rate of chickens by about 10%.

8. Feeding sprouted feed. In winter and spring, green feed is scarce. Frequently feeding chickens with sprouted feed can make hens lay more eggs. According to experiments, feeding chickens with sprouted feed in winter can increase the egg production rate by 10%-20%.

Additional information:

Not only can the above methods be used to increase the egg-laying rate of hens, the following methods are also very effective:

1. Starvation method. In the first month before the laying period of hens, gradually reduce the feeding amount to less than 20% of the normal food intake in the first week, mainly feed water. After one month, gradually increase the feed to the normal food intake of laying hens within one week, and the egg production can be increased by about 30%.

2. Wing amputation. At the second joint outside the wings, the outer end of the wings is amputated by conventional surgery, bandaged, disinfected and anti-inflammatory, and strengthened management to prevent chickens from infection. This can increase the average weight of chickens by 5-8% and increase egg production by 8-20%. However, this method requires certain veterinary surgical knowledge to prevent infection caused by inadequate technology.

3. Earth material method: Adding 3-5% bentonite to the diet of laying hens can increase feed intake and egg production. Adding 3% to the diet of broilers can increase the weight gain rate by an average of 15%.

4. Add vitamin C. Adding 50 grams of vitamin C per ton of feed can increase the egg production rate by 11%.

5. Cold drink method: Giving chickens cold water to drink in hot seasons can increase their food intake and increase egg production by about 12%.

6. Color seduction: Feeding laying hens with colorful troughs can stimulate their appetite and increase egg production by about 10%.

7. Light and dark method: Expose the hens to light for 2 hours and then darkness for 6 hours, and repeat this process to make the hens lay eggs evenly and in large sizes.

8. Aromatic method: Evenly adding 10% aromatic plants, such as onions, garlic, ginger, leeks, celery, etc., to the feed during the laying period can increase the egg production rate of chickens by 10%.

9. Feeding rapeseed cake: Adding 7% boiled and detoxified rapeseed cake to the feed of laying hens can increase the egg production rate by 10-15%.

1. Feeding Acanthopanax senticosus leaf powder. Russian agricultural experts found through experiments that feeding 0.15 grams of Acanthopanax senticosus leaf powder per kilogram of body weight to hens aged 13 to 14 months in the late egg-laying period can produce 242.8 more eggs per thousand chickens on the 10th day of feeding, which is 4% higher than the control group; after 10 days, the egg production is 5.7% to 17.8% higher than the control group.

2. Feeding red pepper. Research by Hungarian animal husbandry scientists shows that drying red peppers, grinding them into powder and mixing them into feed to feed laying hens can not only increase egg production, but also change the color of egg yolks from light yellow to dark yellow or earthy red. The specific method is: add 1% red pepper powder and alfalfa powder to chicken feed, add a small amount of vegetable oil, and then use it to feed chickens, the egg production rate can be increased by 7% to 8%. 3. Starvation method. Experiments by the Ukrainian Institute of Agriculture and Animal Husbandry have shown that the starvation method can increase the egg production of hens. The method is: starve the hens one month before they enter the egg-laying period, that is, gradually reduce the amount of feed from the first week, and control the amount of feed to 1/20 of the normal amount after one week, mainly drinking water, so that the hens are in a highly hungry state. After starvation for one month, gradually add feed to the normal amount, and enter the egg-laying period after returning to the normal amount. Because the nutritional growth of hens is controlled during the starvation stage and turns to reproductive growth, reproductive development and estrogen secretion are promoted, thereby increasing egg production by about 40%.

4. Head cooling method. Researchers at the University of Texas found that if the hen's head is kept cool in summer, the egg production can be increased. An air duct is installed on the top of each chicken house to supply cold air and reduce the temperature of the hen's head. As a result, the egg production rate of the hen increased by about 25%.

5. Electrical stimulation. After years of research, Japanese experts have confirmed that the use of electrical stimulation can increase the egg-laying rate of hens, extending the egg-laying period, which is usually only 14 months, to more than 2 years. The electrical stimulation device is a variable DC power supply with an output of 50-70V. The electrical stimulation rod is connected to the positive and negative poles of the power supply. For safety, a ground wire is connected to the negative pole. Based on the principle that the chicken can adapt, 70, 60 and 50V voltages are selected according to the large, medium and small sizes of the chicken. The method is: first connect the power supply and adjust it to the voltage that the chicken body can adapt to, then contact the tips of the positive and negative rods to the corresponding positions of the ovaries on the surface of the chicken body, and then stop for 1 second after 3 seconds of electrical stimulation, and then stimulate for another 3 seconds. Electrical stimulation should be carried out on the 7th day after the start of laying, and the effect is best. After laying eggs (about a year), continue to lay eggs, and follow the above method, but in principle, each chicken can only be electrically stimulated once a year.

Sixth, the feeding trough coloring method. Israeli experts found that chickens like colorful colors. Therefore, the feeding troughs for feeding hens are painted with various colors to make the colors alternate. The hens' appetite is greatly increased and the egg production can be increased by about 12%.

It is also good to feed more grains and shell crumbs. Crush the seafood residue and mix it with the food. This way the chickens will have nutritious food, and they will love to eat and be willing to lay eggs. Feeding vegetables in a fixed amount is also beneficial. Another important point is to give the chickens enough space to move around. This way the chickens will love to lay eggs and be bigger!

There are many ways for chicken farms to control the egg production of laying hens, such as temperature and light regulation, feed ratio and water control, etc. The most important is the use of hormones. Everyone knows the harm of hormones, so we will not recommend or introduce them to you. There are many other factors that affect the egg production of chickens, such as the stress response of animals. When chickens are transferred from one environment to another, or when they are frightened, they will reduce their feed intake, resulting in a decrease in egg production or even a stop in egg production. The strength and duration of the stress response vary from individual to individual. If the hens caught more than 20 days ago are carefully raised, the stress response should have disappeared. Another important factor affecting the egg production of hens is the age of the chickens. Hens raised under factory conditions can reach the peak of egg production in less than 200 days, while free-range chickens in rural areas need more than 300 days to start laying eggs. The chicks raised in the spring of the year will not start laying eggs until the spring of the second year, and will stop laying eggs in the hot summer. They will enter the peak egg production period after molting in the autumn, and the egg production will drop sharply in the autumn of the third year, entering the elimination period. If the hens you caught from the countryside are three years old or older, it is recommended that you eliminate them. If you want to continue raising them, you should pay attention to the temperature. The appropriate temperature for hens to enter the egg-laying period is about 24 degrees. Now it is winter and the temperature is relatively low. Most of the native chickens in the countryside have stopped laying eggs. In order to keep the hens from stopping laying eggs in winter, the chicken farm uses heating to keep the temperature in the chicken house at about 24 degrees. So you should also pay attention to the temperature of the chicken coop, not too low. If the temperature of the chicken coop is too low, even if you feed the hens with hormones to promote production, it will have little effect. Haha, of course, eggs for babies should not have hormones. Just feed the hens some rice, leftovers and leaves thrown away when picking vegetables, nothing special. By the way, put some sand next to the chicken coop for them to eat, which helps them digest food.

1. Insects are a good feed for chickens. Insects are rich in nutrients and chickens grow fast. Chickens fed with insects have delicious meat and strong disease resistance. Farmers feed chickens with maggots, mealworms, and earthworms to supplement the nutrients needed by chickens, promote chickens to grow more meat and lay more eggs. Feeding chickens with earthworms and earthworm manure can not only reduce the waste of nutrients in earthworm manure, but also save labor and time, which is worth promoting. 2. Chickens are very sensitive to light. In winter, the days are short and the nights are long, and the sunshine time is short, so chickens lay fewer eggs or even stop. If the light time is extended, the brain of the hen is stimulated, which promotes ovulation, and the chickens lay more and larger eggs.
