1、 Preliminary preparation

1. Market research

Laying hens always provide eggs to the market. Eggs can only become commodities if they are accepted by the market and needed by consumers. Therefore, market research must be carried out before purchasing chicken seedlings. For example, consumers prefer brown eggs, white eggs, pink eggs or green eggs. Buy the products required by the market. Only in this way can chicken products have a market. In addition, we should have certain market forecasting ability.

2. Adaptability of chicken breeds

Different varieties have different requirements for environmental conditions. No matter how high the production performance of a variety is, if it can not survive healthily in the local area, its productivity cannot be brought into full play. That is to say, it is not suitable to breed such varieties locally. For example, some light-weight laying hens have high production performance, but they are sensitive and vulnerable to shock, so they can not be raised in noisy places, and should be raised in slow response chicken breeds. In short, before raising chickens, chicken breeders should know the environmental requirements of some breeds and other technical data.

3. Production performance of chicken breeds

The production performance of chicken breeds directly affects the economic benefits of chicken farms. Therefore, only by selecting high-yield breeds, scientific breeding management and strict sanitation and epidemic prevention system can we obtain the possibility of high yield. With an annual production of more than 280 eggs; However, many varieties can not reach this level, and the production performance of different strains of the same variety is also different. If the production performance of the variety itself is not high, and the feeding management and environmental conditions are good, there will be no high production level. Therefore, it is necessary to investigate the production performance of varieties before introduction. The method is to go to the nearby chicken farm to know which varieties have high production performance and strong adaptability, which can be used as the basis for purchasing chicken seedlings, and strictly prevent blind purchase of seedlings. In addition, it should be understood that some imported varieties from abroad are difficult to achieve high production performance in China due to poor adaptability, so attention should be paid when purchasing seedlings. Although purebred is a high-yield variety, due to the long time of breeding, there will also be degradation phenomenon without selection, and the production performance will be reduced. Therefore, it is necessary to be careful when purchasing seedlings, and buy seedlings in a reputable large chicken farm.

4. Investigate the feeding management and disease prevention of the purchased chicken farms

Years of practice has proved that the production performance of the purchased chicken farm is good, the level of raising and management is high, and there are few epidemics. In the future, the survival rate of the chicken farm is high, and the production performance of the adult chicken is good. Therefore, before purchasing the chicken farm, we must investigate the production level and epidemic prevention of the purchased chicken farm. Especially for chicken farms that raise chickens for the first time. A disease - once brought into the chicken farm, it is difficult to survive. This is why the mortality rate of the older chicken farms is higher.

2、 Select high-quality varieties

Different local chicken breeds have different prices. For example, some high-quality native chicken varieties have unique appearance, and the quality of meat and eggs has obvious advantages. When selling, the price is high and the sales is good, the breeding efficiency will be significantly better than the ordinary varieties, so it is reasonable that the price of chicken seedlings is high.

3、 How to select male and female chicken seedlings?

The price of male and female seedlings will vary. If you buy chicken seedlings with high price for female seedlings, half of them are male and half of them are female, but the black-hearted manufacturer sends you 90% of the male seedlings. The price is cheap, but it is the farmers who suffer greatly.

The appearance of male and female chicks' reproductive protuberance has the following significant differences:

Appearance: compared with the cock chicks, the female chicks' reproductive bulge outline is not obvious, atrophy, the surrounding tissues are weak, unrelated, and the feel is soft; The male chick's reproductive bulge is clear and substantial, and its surrounding tissues are firmly connected.

Gloss: In contrast, the reproductive bulge of hen chicks is soft and transparent; The male chick's reproductive bulge surface is tense and shiny.

Elasticity: the reproductive bulge of the female chick is almost inelastic, and it is easy to deform once the external force presses or stretches slightly; The male and female reproductive bulges are elastic, and a certain amount of compression and extension will not make it deformed.

Congestion: The blood vessels of the reproductive bulge of the mother and baby are not developed and do not reach the surface, even if stimulated, it is not easy to be congested; However, the male chick's reproductive protuberance has developed blood vessels, and there are also fine blood vessels on the surface, which can easily be congested with a little stimulation.

Protuberance: the front end of the female chick's reproductive protuberance; Male chicks have rounded reproductive protuberances.

General experience tells us that the male and female can be judged according to the morphological difference of the chicken reproductive bulge. If there is insufficient experience and it is difficult to distinguish it with the visual method for a while, the method of finger touch can be used to check the reproductive bulge of the chicks, and observe the degree of congestion and elasticity at the same time. The combination of these methods can basically identify the male and female of chicks, and also prepare for the clustering plan formulated by farmers. It should be emphasized that for chicks, the appropriate identification time is 2-12 hours after hatching, not more than 24 hours.

4、 Selection method of chicken seedlings

1. Look at the individual appearance; The weak chicks of broilers are not neat, most of them are thin and dry, and they don't like to be open or blind, and their feathers are messy and shiny, so they can't be used.

2. Look at the abdomen; When the yolk is not completely absorbed, the abdomen is enlarged, the umbilical cord is not well contracted, the umbilical cord or the umbilicus is large, there is mucus or blood stains, and the yolk is exposed, which cannot be used.

3. Touch and listen; The touch is soft and weak, the voice is hoarse or noisy, and the grip is inelastic and weak, which is not necessary;

4. Look at the anus; There is more dirt or feces sticking at the anus, so you can't take it.

5. Look at the spirit; He is in low spirits, shrinks his head, stays in a daze, does not like to move, stands unsteadily on his feet, is slow in response, and is afraid of cold.
