Induced factors of chicken disease Many chicken diseases have two causes: one is the actual cause and the other is the cause. The incentive to make chickens more susceptible to a specific disease is the following.
Feeding poorly nutrient-balanced diets, the absence of one or more ingredients, or excessive amounts of any one ingredient can cause illnesses such as rickets, short bones, softening of the brain, and visceral gout. Improper feeding will make the chicken susceptible to disease. For example, uneven blending of vitamin additives can cause certain chickens to overeat, while other chickens exhibit symptoms of vitamin deficiency; improper mixing of salt causes sporadic birds to suffer salt intoxication; olaquindox or furazolid mixed feed causes uneven or excess Chicken poisoning, too short a "feeding tank length" will cause only strong chickens to eat enough feed, weaker chickens will not eat or eat enough feed, so that the chicken population uniformity is poor, and easy to get sick; feed grinding too Fine, chicken poor palatability.
Insufficient vitamin A in dietary nutrient-deficient diets reduces chicken resistance to various respiratory diseases and helminth infections; dietary vitamin E deficiency, chickens are susceptible to exudative quality disease; dietary vitamin D deficiency, chicken Susceptibility to rickets; lack of methionine in laying hens' diets, low chicken egg production rate and easy quail eggs.
Stress factors Various stress factors, such as abrupt transitions, debriding, changing feeds, intimidation, large temperature differences in chicken coops, parasites, and heat stress, can increase metabolic stress in chickens and cause disease outbreaks.
Poor ventilation Due to the poor ventilation of the stifling chicken house, chickens are susceptible to respiratory diseases such as rhinitis and mycoplasma. Poor ventilation during the hot season causes chicken heat stroke and heat stress; the house is poorly ventilated, and the concentration of ammonia gas and carbon dioxide gas in the house is increased, which seriously affects the chicken's production performance. Therefore, it is very important to provide ventilation properly.
Overcrowding of crowded chickens can easily cause respiratory infections. Severe worms and chicken gizzards can cause chicken litter to become damp, moldy, and the air is hot and sweltering.
Parasite infestation Chicken internal parasites such as tapeworms and mites affect the health of the bird and reduce resistance to disease. When used in marginally qualified diets, they can cause nutritional deficiency in chickens. Exoparasites can cause irritation, lead to inadequate chicken rest, reduced resistance to disease, and they can spread pathogenic microorganisms.
Unclean chicken house This is an important factor that can easily cause many diseases such as chicken coccidia and decreased egg production rate. The broiler house is disinfected. The chicken house is not sterilized for a long time. The disinfection is not complete or comprehensive. A disinfectant is often used, causing viruses, bacteria, and parasites to parasite in the shed to varying degrees, causing chicken disease or infectious diseases.
The spread of chicken disease
Many factors and factors have played a major role in the transmission of chicken disease. Infectious factors can be detached from diseased chickens in the feces of infected chickens or in the excretions of infected organs and parts. After the body, the infection will be transmitted from several ways to susceptible individuals.
Drinking Water Spread If you do not pay attention to prevent pollution, infectious feces or parasite eggs that fall into the sink are easily eaten by the chicken.
Litter Infestation Under normal conditions, litter provides ready-made hiding places for bacteria and parasite eggs. Some of them live in this environment for a long time. Since chickens have the habit of continuously feeding pellets from the ground, they pick up infectious substances. The opportunity will always exist.
By vector insects "vehicle insects" are those that do not themselves infect, but can transmit infections from a chicken or an animal to another chicken, such as flies, mosquitoes, ticks, and fleas. In the clinic, chickenpox spread more through vector insects.
Air It can spread the infection from one chicken farm to another. Diseases such as chicken Newcastle disease, infectious bronchitis and laryngotracheitis can spread through the air.
Contaminated incubators and poultry house contaminated incubators or brooders spread infectious diseases to newly hatched healthy chicks such as chicken white quail.
Co-infection of co-infected chickens and susceptible chickens provides a ready-made route for the spread of the disease, not only through physical contact, but also through exposure of chickens to contaminated soil and water. In this case, the diseased chicken should be isolated or eliminated immediately.
People infected by bacteria carriers are those chickens whose infection symptoms are not obvious but still carry certain diseases, especially those chickens that have been infected and recovered but still carry the pathogenic factor. Chicken is a very difficult thing, such as early infection of Marek's disease chicks.
Mechanized carrier carriers include all pathways that accidentally transport pathogenic agents from one place to another, ie, humans, animals, insects, sand, moving vehicles, feed bags, poultry boxes, and contamination. Equipment and so on.
By transporting chickens or chickens off-site to transport certain diseases such as chicken flies, infectious bronchitis, avian encephalomyelitis, and mycoticosis, it is possible to introduce chicken farms without these diseases through these pathways.
The above is a preliminary analysis of the cause of the disease. It can be seen that the occurrence and spread of chicken disease is complicated. In order to maintain a healthy and profitable chicken group, chicken farmers should also be aware of the causes of chicken diseases and the ways of transmission, and take corresponding measures to address different situations. Fowls do not develop or have fewer diseases, so that the benefit of raising chickens continues to increase.
Food Additives are substances added to food. Some additives have been used for centuries. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin.
The advantages of food additives are these followed:
1. Improve the appearance of food.
2. Keep and enhance the nutrition value of food.
3. Increase the variety and conveniences of food.
4. Miantain freshness and prolong shelf life.
5. Provide leavening or control acidity and alkalinity.
