How to treat proventriculitis in broiler chickens? Detailed treatment options
Because in recent years the price and market of broiler chickens have been booming all the way, many people have been attracted to raise broiler chickens. However, some of them are not professional livestock farmers, so they do not know about disease prevention and control in poultry, which has thus caused irreparable losses and therefore also sounded a loud warning bell for those breeders who are just starting out in the livestock profession.
Treatment options for proventriculitis in broiler chickens
Treatment option one: Add Yinhuang oral liquid to the drinking water. It treats both proventriculitis and ventriculitis caused by all causes. After 2 days, the swelling of the proventriculus subsides, yellow droppings and red droppings disappear, and feed intake rises. Use continuously for 3-5 days for a cure.
Treatment option two: For areas with a high incidence of proventriculitis and ventriculitis: add it preventively from 1-10 days of age. Within 20 days, no signs of proventriculitis and ventriculitis are found, and droppings color, growth rate, and feed intake are completely normal.
Treatment option three: Add Beinuo throughout the entire rearing period; it can be used for prevention.
Immunization program for broiler chickens
1 day of age: Within 24 hours of hatching, inject 1 dose of Marek's vaccine subcutaneously.
4 days of age: Infectious bronchitis virus nephropathogenic attenuated vaccine, infectious bronchitis H120, 2 times the dose in drinking water or by eye drop.
7 days of age: Inject 1 dose of Marek's vaccine subcutaneously (fast-growing broiler chickens such as AA chickens, Avian, and Redbro can be exempted).
8 days of age: Newcastle disease strain II at 2 times the dose or strain IV vaccine at 1.5 times the dose in drinking water, or by nasal drop or eye drop.
10 days of age: To prevent Newcastle disease, use strain IV vaccine. Method of use: nasal drop or eye drop. In Newcastle disease epidemic areas or on farms with severe outbreaks, the live vaccine can be used together with the inactivated vaccine, that is, 1 dose of live vaccine by nasal drop, and at the same time 0.2 milliliters of Newcastle disease oil-adjuvant inactivated vaccine by intramuscular injection.
11 days of age: IBD intermediate-virulence vaccine at 1 times the dose by oral drop or 1.5 times the dose in drinking water.
13 days of age: Chick triple oil-emulsion vaccine (Newcastle disease, infectious bursal disease, infectious bronchitis bivalent triple vaccine) injected subcutaneously at 0.3—0.5 milliliters per bird.
14 days of age: To prevent infectious bronchitis, use respiratory-type, nephropathogenic-type, and proventriculotropic-type infectious bronchitis oil-emulsion inactivated vaccine 0.3 milliliters. Method of use: intramuscular injection.
17 days of age: To prevent infectious bursal disease, use an intermediate-strain infectious bursal disease vaccine (Fabelling). Method of use: administer in drinking water.
20—25 days of age: Fowl cholera oil-emulsion vaccine injected subcutaneously at 0.5 milliliters per bird (fast-growing chickens can be exempted).
28 days of age: To prevent Newcastle disease, use strain IV vaccine. Method of use: administer in drinking water.
40—45 days of age: Newcastle, paramyxovirus, and bronchitis (Newcastle disease, paramyxovirus, infectious bronchitis bivalent) triple oil-emulsion vaccine injected subcutaneously at 0.5 milliliters per bird.
Sustainable development of broiler chickens
Broiler chicken is now a common dish on people's dining tables. Compared with red meat such as pork, chicken, as white meat, has the nutritional characteristics of “high protein, low fat, and low calories.” From the perspective of environmental protection and energy saving, chicken also has advantages. Compared with livestock such as pigs and cattle, broiler chickens have a higher feed conversion rate and consume fewer resources. Compared with beef, mutton, and pork, chicken production is more low-carbon and more conducive to sustainable development.
With China's economic development and the continuous improvement of people's living standards, the meat consumption structure of the general public's diet is also changing. Red meat consumption represented by pork is decreasing year by year, while chicken sales are rising day by day with the popularity of trendy fast food such as KFC and McDonald's. As long as it can gradually shake off the negative impact of “mutant chickens” and “hormone-raised chickens,” the development of China's chicken industry will usher in spring.
Methods for preventing bruising during transfer of broiler breeder chickens
When broiler breeder chickens are transferred after the rearing period ends, quite a few breeders are culled due to crushing injuries and bruising, especially breeder roosters. The selection requirements for breeder roosters are very high; if there is even a slight injury to the wings or legs, they will be culled. In response to the technical requirements for transfer, the following measures to prevent bruising are summarized:
① Feed 5-6 hours before transfer to avoid the chickens eating too full during transfer and causing greater stress. First remove all the feed troughs from the chicken house, continue supplying drinking water, and then remove the drinkers from the chicken house before catching the chickens.
② To reduce commotion in the flock, it is best to catch the chickens and put them into crates during a time with dimmer light. When catching chickens, first turn off 60% of the lights in the brooding and rearing house. Red or blue light can be used to reduce the chickens' visual sensitivity, dim the light intensity, keep the flock quiet, and make them easier to catch.
③ A chicken-catching net can be used to herd part of the chickens into a corner of the chicken house. Do not herd too many at a time. Then grasp the chicken by the legs with your hands. When catching, be fast, accurate, and steady. Do not pull hard, and do not grab the chicken's wings, head, or neck, so as to avoid injuring the chickens.
④ It is best to use plastic crates for loading the chickens, and do not pack each crate too crowdedly. When catching chickens, putting them into crates, loading, and unloading, movements should be gentle. Do not throw them roughly. Drive smoothly during transport to prevent the chickens from being bruised.
Although the price and market of broiler chickens have been good in recent years, it must be said that poultry, as a kind of poultry, basically cannot escape the diseases that poultry commonly suffer from. Therefore, although breeders cannot prevent broiler chickens from ever getting sick during the raising process, basic defensive measures still need to be taken.
