First, many reasons, resulting in excessive burden on chicken liver and kidneys.
▷ Due to the rapid growth rate of chicken in the early stage, the burden of chicken liver and kidney is too heavy, and the function is also sharply weakened. Coupled with frequent and long-term use of antibacterial drugs in large doses, it will seriously aggravate the damage to organs such as chicken liver and kidneys.
☞ For this reason, many toxins accumulate in the body and cannot be discharged in time, so once there is some stress or other abnormal situations, the chicken can immediately cause the onset of the disease. In fact, in the later stage of breeding, it is also a symptom of many unfavorable factors accumulating to a certain extent and concentrating on outbreaks.
Second, the existing breeding mode has led to a high incidence of chicken diseases.
▷ The current broiler breeding model is still based on "small-scale large groups". In layman's terms, there are more breeders, but the scale of each household is not large, which causes a fierce infectious disease caused by poor management of one family, then this epidemic will soon spread to other breeders, bringing great uncertainty to chickens.
Third, the influence of mold and its toxins.
▷ At present, the most serious mold pollution is that the raw materials used in the production of feed have been seriously contaminated by mold before processing. Then after the accumulation of mycotoxins in the first 30 days, it is easy to appear after 30 days of concentrated symptoms of mycotoxin poisoning, which is the most important.
To this end, it is recommended that every 5 days after the seven days of age of chickens, mix a deenzyme preparation, each time for seven consecutive days. (Repeat until out of the bar) This minimizes the serious effects of mycotoxin poisoning on the chickens.
☞ In addition, a small amount of mold and its toxins can cause chicken immunosuppression, low antibody levels, poor growth and development, and substandard weight, which is one of the main triggers for the high ratio of materials and meat.
If a large number of mold and its toxins can lead to the onset of disease in chickens, toxins into the body can cause different degrees of pathological changes in the body's organs, and the main damage to the target organs are: gastrointestinal, intestinal, liver, kidney, bone marrow, etc. Common gastrointestinal erosive ulcers, as well as prominent erosions of the muscular stratum corneum, liver bleeding, yellowing, and renal bleeding or anemia are common.
Such as: can cause liver lesions, weight loss, death spike increase;
Can cause mouth ulcers, hepatomegaly degeneration, abnormal feathers, decreased daily weight gain;
, which can cause a decrease in immune performance;
, which can cause reduced feed intake in chickens, slow growth, immunosuppression;
Ochre mycotoxin A can cause enteritis, renal degeneration, and slow growth in broiler chickens.
▶ In summary, the bacteria and their toxins accumulate in the chicken body for a long time, and the impact on the chicken cannot be underestimated, and it is also one of the main precipitating factors for the frequent occurrence of chicken problems after the age of 30 days.
Fourth, the surrounding environment of feeding has not been well purified.
▷ Such as the pile-up of chicken farm manure everywhere, as well as the flow of sewage inside and outside the chicken farm, the random dumping of sick and dead chickens, and the littering of immunization vaccine bottles, these have made the chicken farm environment worse and worse. Over time, it will become more and more difficult to raise good chickens.
Fifth, management factors.
▷ Regarding management factors, focus on the "humidity" problems that are easy to be ignored, such as low humidity in the early stage, which can cause the chicks to dry the respiratory mucosa, the brittleness of the tracheal mucosa is enhanced, and pathogenic bacteria can take advantage of the deficiency at any time; and in the later stage, due to the increase in chicken excrement and the inability to clean up in time, the humidity in the house is too high, and the high temperature and high humidity environment in the house can lead to the occurrence of diseases of chicken air cystitis, coccidiosis and bronchial embolism.
To this end, it is recommended that breeders and friends should slowly summarize a set of standardized feed management processes suitable for themselves according to the actual characteristics of their own chicken coops, which is actually a sum.
