4 common intestinal diseases in broilers

With the increase of environmental protection and control, the difficulty in finding aquaculture land and the increase in labor costs, cages have gradually become the mainstream mode of cage broiler farming because of their small footprint, low cost and high performance recently . How to do a good job for broiler cages and achieve maximum production benefits requires solving a series of related problems.


1 Intestinal flora imbalance

The intestinal flora of broilers is dysfunctional. The main clinical manifestations are foam cecal feces, orange feces or large cecal faeces; the amount of drinking water increases. When dysbacteriosis occurs, the performance of broiler chickens may not be affected or the feed intake may be reduced, thereby affecting growth; foot disease is more common. After using antibiotics, sometimes it will return to normal, but it will still be susceptible to the whole growth period and it will not form permanent immunity. If the cause is not removed, it will still recur.


2 Coccidia

Because caged broilers grow in cages and the feces are cleaned regularly, there is less chance of exposure to feces than ground-level and net-fed, and the chance of coccidiosis is lower than that of ground-level and net-fed. However, for broiler farms that have been caged for many years, the prevention and control of coccidia must be highly valued due to the incomplete cleaning and disinfection of chicken manure on cages, cages and scraping manure plates.


3 Necrotic enteritis

There are many factors that cause necrotic enteritis, but Clostridium perfringens is a ubiquitous anaerobic microorganism that causes necrotic enteritis. When broilers are infected with subclinical coccidiosis, the content of starch and protein in the feed is too high. When some wheat, barley and oats are used instead of corn as energy feed, Clostridium perfringens can breed in the intestine. It produces toxic alpha-toxins that are sensitive to broilers and cause disease.


4 Mycotoxin accumulation poisoning

The most common type of feed pollution is corn pollution, followed by the contamination of soybean meal and chowder, followed by pollution in the trough and contamination of the finished material. The contamination of mold and its toxins can cause damage to various tissues of the chicken system, especially the digestive system such as muscle ulcer, glandular stomach enlargement, intestinal mucosal shedding, intestinal flora imbalance. Clinical manifestations are diarrhea and pull digestion of feed feces. The popular glandular gastritis and musculoskeletal gastritis are basically caused by the current mold and its toxins. However, due to the fact that feed moldy factors cannot be completely eliminated, commercial broilers often face the current situation of unhealthy intestinal tract and digestive system dysfunction.


What are the causes of intestinal diseases in broilers?

 1 Waterline management is not in place

The waterline cleaning is not complete, especially in the summer, the temperature is high. During the feeding process of the chickens, vitamins and other nutrients are added to the chickens, resulting in a large number of bacteria in the waterline. Due to the large amount of bacteria in the waterline, it is easy to appear in the medicine for a few days after the drug is administered. The chickens will have repeated symptoms such as encapsulation of the liver and glandular gastritis caused by E. coli.

2 The facilities and equipment in the chicken house are not flushed and disinfected.

In order to increase the density between the batches of chickens and save the chicken time, the cages are specially used to wash the chicken houses. Due to the inconspicuous flushing, chicken droppings and feathers remain in the grid from time to time. The sewage that washes the chicken house also has residual residue that cannot be hanged on the scraping board. These factors cause the coccidia to persist in the chicken house, which causes the chicken to be infected with coccidia.

 3 What are the effects of mycotoxins on broilers?

At present, the most harmful mycotoxins to chickens are: aflatoxin, zearalenone, T-2 toxin, ochratoxin. There is a synergistic effect between various mycotoxins in the feed. The synergistic effects of several mycotoxins on animal health and production performance are greater than the side effects of any single mycotoxin alone, and feed ingredients and full-price materials often coexist. Several mycotoxins make the clinical symptoms more complicated when the chickens are poisoned, resulting in damage to the liver of the chickens, decreased feed intake, and increased feed-to-meat ratio.



01 Strengthen the scouring and disinfection management of chicken houses

Strengthen the management of the hedge team. After scouring a chicken house, the management personnel should check the narrow angle between the corners, equipment, cages, net frame and scraping belt in the chicken house. Clean and clean again, resolutely put an end to chicken dung, feather residue and so on.

 02 Thorough immersion disinfection

It is especially important to thoroughly soak and disinfect the waterline before the chicken. The immersion and disinfection is not complete, which will cause the chickens to be infected with the stomach and stomach glandular gastritis, anti-repeated drugs, and the effect is not good, increasing the cost of medication and affecting the meat of the chickens. ratio. It can lead to intestinal diseases that are easy to flock, and the intestinal inflammation is diarrhea, which affects the weight gain of the flock and affects the performance of the pen.

 03 Feeding coccidiosis with broad-spectrum antibiotics

In the newly built caged broiler farm, a coccidiosis drug was administered at 13 to 14 days to prevent coccidiosis. For many years, cage chicken farms need to feed two coccidiosis drugs to prevent coccidia. According to the feces of the flock, determine whether to use broad-spectrum antibiotics to treat the diarrhea of enteritis.

 04 Feed mold

(1) It is necessary to strictly control the procurement of raw materials, prevent moldy materials from entering the warehouse, control feed processing, preparation and transportation, control the storage environment of feed, minimize storage time, and prevent mold and deterioration of feed in poultry houses.

(2) Add mold adsorbent to the feed in summer and autumn.

(3) After the chicken is passed, the chickens are patrolled in the daily house, and the weakly disabled chickens are examined. If there is a suspected mold infection, the chickens are fed a mold inhibitor.
