Chicken meat and eggs are a kind of indispensable food on the market. China's demand for chicken meat and eggs is also constantly increasing, so this has high requirements for the concentrated breeding of broilers and layer chickens. Need to pay attention to quality control, so when you encounter problems in the chicken breeding process, you must carefully figure out exactly where the problem lies and solve it in a timely manner. The following is a brief description of some of the problems and their causes during the chicken raising process, so that farmers can find out the problem in time.
6. How long is the light time of laying hens generally suitable?
Under normal circumstances, the laying time of the laying hen is between 16.5 and 17 hours per day. Too much light will not help the laying of eggs, and too little light will reduce the egg production rate.
7. How to improve the egg production and laying rate of laying hens?
There are many factors that affect egg production and egg production rate, which can be divided into: environment, management, disease and feed. In terms of feed, feed digestibility, methionine lysine content, metabolic energy content, various vitamin content, Daily feed intake has the most impact. Only by increasing these indicators can high egg production and egg production be achieved.
8. How can we use protein feed more effectively?
First, the digestibility of raw materials is an important indicator. Only raw materials with high digestibility can make full use of animals. Second, the balance of energy and amino acids in full-price materials is important. When energy is high compared to amino acids, animals use Reduced food intake results in poor animal performance, and conversely, reduced protein utilization. In addition, when the amino acid content of protein raw materials is unbalanced, the utilization rate of protein feed becomes low; in addition to the above factors, some trace nutrients related to protein metabolism, such as vitamin pantothenic acid, B6, biotin, etc., should be considered. These ingredients If the content is not enough, the utilization rate of protein feed will decrease. The solution to the above problem is to use computer software and reliable vitamins and trace elements.
9. Why do chickens often die in cages?
The chicken is undead. In fact, what we have seen is internal bleeding caused by liver rupture, and the cause of liver rupture is fatty liver. The dead chicken is pale and the anatomy shows that the abdominal cavity is full of blood clots. Observe the liver surface carefully It can be seen that there is a rupture mouth. This situation is due to the accumulation of large amounts of fat on the liver, which makes the liver very brittle and easy to rupture. When there are certain factors that frighten the chickens (such as the movement of mice at night), chickens Only severe activity led to the death of liver rupture. Fatty liver in chickens is caused by energy metabolism disorders in chickens. Chickens with fatty livers show decreased egg production rate, short peak maintenance time, and delayed flock production time. Energy metabolism disorders are mainly involved in energy metabolism. It is caused by a decrease in the synthesis of an enzyme, which is most likely caused by a decrease in the body content of coenzymes (mainly vitamins such as biotin, pantothenic acid, choline, etc.). The solution is to add these vitamins to the feed species, or choose A multivitamin with more reasonable formula and more reliable quality.
10. What are the effects of protein feed and energy feed on egg production?
In general, the level of energy to egg production is related to the peak maintenance time, and the protein content has a great relationship with the egg-to-feed ratio. The above theory is based on the normal metabolism of various substances in animals.
11. How to solve the problem of cleft palate and bleeding among young chickens?
Cleft palate and bleeding in young chickens are caused by lack of biotin in the feed or poor quality of biotin, uneven mixing of the feed, and some chickens cannot eat biotin. The above problems have brought great difficulties to the weight management of reared chickens. The solution is to add good biotin to the feed, or use a compound multidimensional with high biotin content.
