How to improve the laying rate of native chickens?

Native chickens generally refer to chickens raised in rural areas, and native eggs are also a necessity for every family, not to mention the difference in nutritional value between native eggs and foreign eggs, but the taste will still be different. Native eggs are more fragrant than foreign eggs, and the color of egg yolk is also different. Therefore, people are more in pursuit of buying native eggs, which opens up a market for native chicken farmers and does not worry about selling at all. In this way, to increase the laying rate of native chickens is to increase economic income, so let's take a look at it with the editor.

How to improve the laying rate of native chicken

1. Add thermal insulation and lighting facilities

Cover the wind barrier around the chicken house, keep the floor clean, spread the grass, paste the doors and windows, put down the straw curtain at night to keep warm or ignite to heat up, so that the room temperature is always above 10 ℃. If you raise a small number of native chickens, you can drive them back to the house at night.

2. Strengthen the management

There should be a playground outside the chicken coop, and rest stands should be set up inside the chicken coop, with a breeding density of 5 per square meter. Before releasing the chickens in the morning, you should pay attention to adjust the temperature difference inside and outside the house to prevent the chickens from catching cold. Usually to feed hanging food, that is, feed high, in order to promote its exercise, help digestion, strong chicken body. Persist in lighting for 13 to 14 hours a day, and turn on the electric lights when the natural light is insufficient. In winter, it is appropriate to increase the number of feeding times, so that less frequent feeding, feeding 3 to 5 times a day, to ensure that each chicken is fed fully, which is not only conducive to its own heat production, but also conducive to weight gain.

3. Feed diversification

The fine feed of native chicken should be based on corn, sorghum, wheat bran, etc., and green feed should be based on carrots, cabbage, spinach and so on. In the local chicken laying period, but also feed some bean cakes, corn flour, shell meal, fish bone meal and other protein and mineral feed, and ensure adequate drinking water every day.

4. Mix the material with liquor

The laying rate of native chicken can be increased by about 18% and its disease resistance can be enhanced by adding 30 grams of liquor of about 60 degrees per kilogram of feed and mixing it well.

5. Make full use of feed additives

Adding 0.05% choline chloride, 0.15% methionine and appropriate amount of natural yeast to the feed can increase the laying rate of native chickens by 3%.

6. Do a good job of disinfection and epidemic prevention

Often clean the feces and sundries of the chicken coop, change the cushion regularly, usually pay attention to disinfect and feed Chinese herbal medicine with sue water, or drink water with 0.5% potassium permanganate solution.

How to prolong the laying of native chicken

1. Provide enough protein. A chicken needs about 1215g of protein for every egg it lays. In general, for every 10% increase in the laying rate, the dietary protein level should be increased by about 1%. In addition, when the egg production rate was expected to increase, the diet with higher protein level should be fed one week in advance, and when the egg production rate began to decline, the dietary protein level would be postponed to lower standard by one week.

2. Make up the light. Light has obvious stimulating effect on gonadal activity. Artificial light supplement generally starts from 21 weeks old, increases light by half an hour a week at 21-24 weeks, and increases light by half an hour every 2 weeks after 25 weeks, until the light time reaches 16 hours a day. In the last 4 weeks of laying, add another hour of light every day until the end of the first laying year. It is better to replenish the light from early morning to before dawn every day.

3. Control energy. When the laying rate reaches 90%, the metabolic energy per kilogram of feed should be controlled at 2700-2750 kcal, so that increasing feed protein can promote the rapid arrival of the egg laying peak.

4. Make up the green. Green feed is rich in protein, vitamins, chlorophyll and many unknown nutritional factors. Proper feeding of some green feed can activate the reproductive function of chickens and increase egg production.

5. Supplement calcium. According to the study, the effect of calcium supplementation to laying hens is the best at 12: 18 every day. The content of calcium in the diet of laying hens is generally higher than 3%. During the peak laying period (the laying rate is more than 80%), the content of calcium in the diet can be increased to 3.5% and 4%. When the laying rate is 80% and 65%, the calcium in the diet should be kept at 3% and 3.25%. In addition to supplementing calcium in the feed, placing calcium basins containing shells and bone powder in the house or on the playground to allow chickens to eat freely also has good results.

6. Reduce stress. Laying hens are very sensitive to environmental changes, especially light laying hens are particularly neurotic. Any change in environmental conditions can cause stress response and lead to a sharp decrease in the peak of egg production. Therefore, in the critical period when the flock reaches the peak of egg production, all effective measures should be taken to reduce stress and keep the flock high and stable production.

7. Skillful use of additives. Feeding baking soda can increase the laying rate and eggshell strength, reduce egg breaking; adding 0.15% choline chloride can maintain the laying rate of more than 79%.

8. Ensure the health of the flock. The hens in the peak period of egg production have the most vigorous reproductive function and the strongest metabolism, which is the period of the most protein synthesis. At this time, the chicken body is under huge production stress, the resistance is weak, easy to get sick, we must pay special attention to the environment and beverage hygiene, so that the chickens will not be infected by pathogens.

What kind of native chicken lays high eggs?

Generally speaking, native chickens can lay about 120 eggs a year because they have to hug their nests, while some improved breeds can lay 180 eggs a year, such as Gushi Chicken and Xianju Chicken in Xijiang.

Five black chickens lay about 180 eggs a year, with a peak laying rate of 86%. Five black chicken "black hair, black skin, black meat, black bone, black viscera", the egg is green, is a collection of natural black food and green food as one of the rare birds, its green shell eggs are known as "Oriental Divine Egg, Huaxia Pearl". It is an ideal nutrition and health product.

In breeding, we should mainly pay attention to the early heat preservation work and vaccines, pay attention to weather changes before stocking, and try to choose sunny days to open.

How to choose eggs

1. Eye identification: the eggshell of fresh eggs is rougher than that of old eggs. Smooth, moldy eggs have stains.

2. Identification by hand: the weight of good eggs is moderate and the weight of low-quality eggs is lighter.

3, smell identification: you can take a breath of hot air on the egg and then smell the good egg with your nose. There will be a slight smell of quicklime.

4. Ear identification: shake the egg in your ear and shake it with your hand. the sound of a good egg sounds more solid, or you can gently touch a shoddy egg with a few eggs in your hand. The rattling sound is hatched eggs or empty water eggs.

So we know that if we want to improve the laying rate of native chickens, we should give them more nutrition and give them a good environment. As long as the laying rate is increased, the income will be increased. For laying hens, eggs are valuable. In short, farmers must work hard on management and nutrition, the editor summed up these knowledge points hope to help you.
