Description
technical field:
The present invention relates to technical field of pharmaceuticals, particularly relate to a kind of chicken-raising method of broiler chicken.
background technology:
In the breeding process of broiler chicken, easily because ascites symptoms causes the large quantities of death of chicken fowl, cause heavy losses to raiser.This illness is generally infect peak period when 15-20 days.Dorking abdominal dropsy, (Ascites syndrome, AS), also known as pulmonary hypertension syndrome (Pulmonary hypertension syndrome, PHS), be a kind of syndrome Hou Qun mainly betiding commercial generation Broiler chicks being formed as feature with hypertrophy of right heart-ascites.(seventies is to the mid-80) is mainly reported in High aititude anoxic area at first, and the report nearly ten years in low altitude area about this disease also increases increasingly, and the broiler breeding industry of China in serious harm.The risk factor of dorking abdominal dropsy: definitely the partial pressure of oxygen of anoxic high altitude localities is low, Broiler chicks makes the incidence of disease of AS increase substantially because of atmospheric anoxic.When thoracic deformity during Ca,P metabolism obstacle and the serious mycotic infection of respiratory system, the incidence of disease of AS can be made to raise because of respiratory hypoxia.Relatively hypoxia: the AS incidence of disease can be made obviously to increase because increasing weight fast when feeding particulate material.Male broiler chicken metabolic rate is higher, and oxygen demand is large, and the AS incidence of disease is high.Cold makes animal oxygen demand increase (test shows, increases by 93% when Broiler chicks oxygen demand is than 23 DEG C when 7 DEG C), and the incidence of disease of AS can increase considerably.The factor of broiler chicken to be the basis that AS occurs: AS be modern goods itself is for the product of Broiler chicks structure and function contradiction.The heredity of broiler chicken is selected mainly to concentrate on meat production in the past, the aspect such as the price of deed and the speed of growth, and ignoring the concern that each organ is developed in harmony, result causes the breathing of commercial generation Broiler chicks and the circulatory system greatly to reduce the adaptability that the poor environment such as anoxic, cold stimulates.Particularly often bring out hypertrophy of right heart and exhaustion-Ascites because of right cardiac load increase.Paragonimus cyst (lung weight/body weight) as Broiler chicks only has 60% of laying hen of the same age, therefore it is lower to the compensatory adaptive capacity of anoxic; Under the stimulation of cold and anoxic, cardiac muscle easily damages (the burst size increase of the Cardiac troponin T NT of specificity reflection cardiac structure infringement).This factor is in the main cause of plains region cultivation chicken fowl.As: diet excessive concentration, grows too fast, causes anoxic, cause the generation of Ascites to the increase in demand of oxygen; Sodium salt content in feed is too high, the osmotic pressure between body tissue cell and blood can be made obviously to strengthen Humoral immunity hypodynamia, thus cause the generation of Ascites.The clinical symptoms of AS and pathological change can summarize three aspects: (1) whole body hemostasis and congestive liver malnutrition (cirrhosis).It is that belly expands that AS suffers from the typical clinical symptoms of chicken, and skin of abdomen is shinny, has fluctuation when pressing with hand, and sick chicken is fluffy by hair, is reluctant to stand, slow in action, walks about like penguin shape.Expiratory dyspnea, several cases cockscomb, wattle is aubergine, skin cyanosis.Cut open the visible liver hemostasis of inspection, enlargement and fibroid sclerosis, a large amount of limpid or bale of straw liquid is amassed in abdominal cavity, can be mixed with cellulose mass or floccule in liquid.(2) right cardiomegaly, expansion, heart valve occurs that pathologic changes.(3) lungs hemostasis oedema.These are all the characteristic features of cor pulmonale.Therefore, generally at present explain the morbidity link of AS with the pathogenesis of cor pulmonale: namely risk factor → pulmonary hypertension (namely right cardiac load increases) → hypertrophy of right heart and exhaustion → whole body hemostasis and congestive liver malnutritive, posterior vena cava backflow obstruction and ascites formation.
For avoiding this illness, in existing cultural method, usually adopt following means: 1, add selenium pellet 500 grams in every double centner feed, and add vitamin E in right amount.The method of this microelement-supplementing, preventive effect is good, but too late for the then treatment of having fallen ill.2 pairs of sick severe one can gavage with Aquarium every chicken half, vitamin C 10 milligrams.To the available hydrochlorothiazide tablet of chicken group 100 milligrams, add glucose 125 grams, after mixing, add water 20 kilograms, every day 2 times, serve on 3 days, use No. 16 syringe needles to carry out abdominocentesis to the obvious sick chicken of ascites, release hydrops, the death time can be made 2 ~ 4 days to postpone.This method can only be pushed into the death time, for treatment broiler chicken leaves the time.3, Chinese medicinal formulae is with two ugly, rhizoma alismatis, akebi, pokeberry root, rhizoma atractylodis, umbellate pore furgus, millet, each 500 grams of rush, and 250 grams, the leaf of bamboo, grinds to the powder altogether, and every chicken feeds 1 gram at every turn, is used in conjunction 3 days.This method has certain effect for dorking abdominal dropsy, but, find through overtesting, be efficiently only 60% about, be i.e. effect deficiency.
On the basis of existing technology, aim to provide a kind of method simple, easy to use, prevention and cure dorking abdominal dropsy is effective, obviously can reduce the chicken-raising method cultural method of the broiler chicken of the loss that therefore illness is brought to raiser in the present invention.
