Eyesight knowledge of low-yield chicken

The low egg production rate of chickens is often caused by part of discontinued chickens and sick chickens. They only consume no eggs or produce few eggs. If large groups are eliminated, it will inevitably cause great economic losses. If chickens continue to be raised, Due to the existence of this part of the chicken, it can't make ends meet. In order to improve economic efficiency and ensure a high-yielding and efficient flocks, it is determined to eliminate some of the low-yield, discontinued, and sick chickens, and the egg production rate will reach 90%. This will not only reduce feed consumption, but also increase the elimination of these chickens. The egg production rate is about 10%. For this reason, the following describes several methods for identifying low-producing chickens.

1. See crown gall: High-yielding cocks are large, plump, and bright red. The upper part of the crown is often turned to one side; low-yield, discontinued chicken cocks are small and shrunk, pale red, dark red, or white, sometimes with a bran-like shedding substance. , There are squats.

2. Look at pigments: The yellow pigments of the anus, gills, face, gills, and toes of high-yielding chickens are moved to the yolk, so the color of these sites changes from yellow to light yellow or white; the yellow pigment of low-yielding chickens is not clearly deposited. White shell chickens are more pronounced than brown ones.

3. Look at the anus: The relaxation of the anal sphincter muscles, elasticity around the squeezing contractor muscles, a moist sensation, and immediate contraction, out of viscous secretions, such chickens are high-yielding chickens; anal tightening, abdominal muscle compression around Elasticity, without a moist sensation, is a low-yielding chicken.

4. Look at the feathers: High-yielding chicken feathers are earthy, unkempt, unsmooth, not smooth, and the feathers on the neck, back, and chest are shed or discolored; chickens that are on or off production are plump, tidy, and have few broken feathers.

5. To see the feces: high-yield chicken manure and more soft, large water content, landing forming; stop chicken and manure dry, was strips, some chickens pull yellow or white green dilute feces, feather contamination around the anus.

6. To see the spirit: high-yield chicken eyes round and spirited, quick response, strong appetite; low-yield chicken, semi-closed eyes of chicken eyes, depressed, loss of appetite.
