Choose good chicken seedlings in order to raise healthy chickens, how to choose chicken seedlings?

If farmers want to raise chickens, they must first choose chicken seedlings, which are related to the growth and development of their offspring. The selection of chicken seedlings is related to the follow-up development and the income of breeding. So how to choose the chicken seedlings?

I. preliminary preparation

1. Market research

Laying hens eventually supply eggs to the market. Eggs can become a commodity only if they are accepted by the market and are needed by consumers. Therefore, market research must be conducted before buying chicken seedlings. For example, consumers like brown finished eggs, white shell eggs, pink shell eggs or green shell eggs. Buy products that are in market demand. Only in this way can chicken products have a market. In addition, there must be a certain degree of 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 cannot survive healthily locally, its productivity will not be brought into full play. In other words, it is not suitable to raise such a variety locally. For example, some light laying hens have high production performance, but they are sensitive and easy to be frightened, so they can't raise this kind of chicken in noisy places, but should raise slow-reflecting breeds. In short, before raising chickens, chicken breeders should first know the environmental requirements of some varieties, as well as some other technical materials.

Second, select high-quality varieties

The price of chicken seedlings varies with different native chicken breeds. Like some high-quality native chicken breeds, the appearance is unique, the quality of meat and eggs have obvious advantages, when the sale price is high, good sales, breeding efficiency will be significantly better than ordinary varieties, so the high price of chicken seedlings is also reasonable.

Third, the selection method of male and female chicken seedlings

There will be a difference in the price of male and female seedlings. You buy female seedlings with high prices, half male and female, but black-hearted manufacturers give you 90% of the male seedlings, the price is cheap, but it is the farmers who suffer big losses.

There are significant differences in the appearance of reproductive protuberance between male and female chicks.

Appearance: compared with rooster chicks, the outline of reproductive protuberance of female chicks is not obvious, atrophy, the surrounding tissue is weak, there is no connection, and the feel is soft; while the outline of reproductive eminence of male chicks is obvious and substantial, and the connection between the surrounding tissue is stable.

Luster: in contrast, the reproductive bulge of the hen is soft and transparent; the surface of the reproductive bulge of the rooster is tight and shiny.

Elasticity: the reproductive bulge of the female chick is almost inelastic, and it is easy to deform once the external force is oppressed or stretched a little; while the reproductive bulge of the male chick is elastic, coupled with a certain amount of pressure and extension, it will not deform.

Hyperemia: the blood vessels of the reproductive eminence of the female chicks are not developed and do not reach the surface, even if stimulated, it is not easy to be congested, while the reproductive eminence of the male chicks has well-developed blood vessels and small blood vessels on the surface, and it is easy to be congested with a little stimulation.

Protuberance: the front end of the reproductive eminence of the female chicks is pointed; the front end of the reproductive protuberance of the male chicks is round.

Male and female can be judged according to the morphological difference of reproductive eminence of chicks. If you are inexperienced and it is difficult to distinguish with the eye, you can use the method of finger touch to check the reproductive eminence 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 chicks and prepare for the grouping plan made by farmers. Finally, it is emphasized that for chicks, the most appropriate identification time is 2-12 hours after hatching, preferably no more than 24 hours.

Fourth, the method of selecting individual chicken seedlings

1, look at the appearance of individuals: broiler weak individual is not neat, mostly thin and withered, eyes do not like to open or blind, feathers dishevelled, no luster, such can not be.

2. Look at the abdomen: when the yolk is not absorbed completely, the abdomen is dilated, the umbilical cord does not contract well, the umbilical cord or umbilical hole is very large, there is mucus or with blood stains, and the yolk is exposed.

3. Listen after touching: feel soft and weak, cry hoarse or cry endlessly, hold in the hand inelastic, weak, this can not be taken.

4. Look at the anus: there are many dirt or feces sticking to the anus, which can not be taken.

5. Look at the spirit: depressed, dull, inactive, unstable on both feet, slow to react, afraid of the cold, can not want.
