Why not chicken produce much egg

Egg-laying chickens, where are the profits? Certainly the higher the egg production rate and the longer the peak period, the more we make money, so why do some egg breeders have no peak egg production period? Today we mainly talk about this issue.

Improper lighting for a long time

Recently, customers often responded to me. When young chickens were given 16 hours of light all day long, and some even gave 24 hours of light for a long time, so long time the light goes on. It can be imagined that the late production will be good or bad. it is good? In fact, there are not many such cases, but there are many customers who spend more than 12 hours of long-term lighting for a long time in order to achieve weight. This situation will result in a light refractory period to the light stimulus at the time of opening due to a longer light period during the breeding period, causing the laying hens to be insensitive to light production and delaying production.

Weight and uniformity are not up to standard

Due to the high density of chickens, poor environment or low nutritional levels, poor raw materials, or disease problems, chicken populations may not be able to meet the standards for weight and uniformity.

The development of the chicken body has a sequential nature. The more important the organs are, the sooner it will develop, and it will be irreversible. From the day of hatching, immunity and digestive organs develop around 6 weeks. From the hatching to 15 weeks, it is the golden period of bone development. After 15 weeks, the length and thickness of the bone are basically fixed; then the muscles and reproductive organs develop. Immune organs of chickens with a body weight of 5 to 6 weeks were well developed. The body weight at this stage was positively correlated with the final production of eggs, and was negatively correlated with the rate of death. This was the 35-day life-long concept.

For the degree of uniformity, first affect the peak speed after the start of production, the peak of the peak period and the final production of eggs, it was confirmed that the uniformity is 3% lower, and each chicken needs to produce 4 eggs less; then the chicken with poor uniformity is inferior. The rate of death scouring is high, the group is bullied, and the scrofula and licking are serious.

Improper physical development

Physical = Robust Muscles + Compatible Tibias + Compatible Weights. Body size is related to body weight but not to body weight. Relatively speaking, physique is far more important than weight. The main cause of poor physical development is the level of nutrition, especially the early amino acids (methionine, lysine, tryptophan and its derivatives, etc.), crude protein, organic calcium and phosphorus, energy level, quality of feed ingredients, freshness, etc. Impact; There is also the flock density, whether in time to group management (at least divided into large, medium and small groups, large with the big can be developed together, small and small together can also be well developed, afraid of the size together); Chicken health status.

Chickens are prone to "big and thin" chickens and "small and fat" chickens. "Large and thin" chickens do not have enough nutrition for the development of reproductive organs. The body is in poor condition and the fullness of the pectoral muscles is not enough, so that it cannot be opened normally. Although “small and fat” chickens have a large amount of fat, but their genital organs are too late to grow, they cannot only start production at the right time, but they also have no eggs for life because of the transitional deposition of fat; they do not respond well to light stimulation. Delayed chicken production, affect the speed of the peak, the duration of the peak period and the peak level; easy to produce double yellow eggs, rectal prolapse, licking and other anal sex rate increased.

Use inferior feed, biological products

Poor quality of feed raw materials, toxic and harmful substances such as mycotoxins exceeded standards, not only affect the intake, prone to glandular gastritis and other diseases, and then affect the future weight and uniformity of chickens, and the toxic and harmful substances such as mycotoxins affect the immune organs. Function, resulting in immunosuppressant, makes chickens susceptible to disease, and is not easy to treat after onset. There is also the choice of vaccine, but also to choose a relatively new type of strain, the regular manufacturers of vaccines, otherwise it will cause immune failure or what disease to prevent what disease. Unhealthy chickens, or being in a sub-healthy state for a long time, will eventually result in low egg production rates and even no peaks.
