Etiology and control measures of goose producing soft shell eggs

First, schistosomiasis goose began to produce thin shell eggs, soft shell eggs or misshapen eggs. Afterwards, the mental quivering, drowsy, loss of appetite, abdomen enlargement, discharge of eggshell fragments or flow out of lime-like fluids, and eventually the body temperature rises, the desire to drink increases, the cloacal outgrowth, and the onset of illness is 2 to 7 days.

Prevention

(1) Strengthen prevention. Check the feces regularly and find that the eggs are immediately isolated and treated.

(2) Goose dung must be fermented in order to kill the eggs.

(3) Use hexachloroethane (fluthizone), 0.2~0.5g per goose, stir in a small amount of concentrate, make a small pill, take it once a day, and even serve 3 times.

(4) Combustion of carbon tetrachloride, 5 to 7 days apart, compounded once (preferably with equal amounts of liquid paraffin each time).

Second, the lack of vitamin D or calcium in the feed, phosphorus goose fodder lack of vitamin D (especially vitamin D3), or calcium content in the feed is not enough, improper ratio of calcium and phosphorus, or cloudy rain for quite some time, the sun goes less than the sun , can cause metabolic disorders of the goose and onset. The production of thin-shelled eggs and soft-shelled eggs began, and then the egg production decreased and even completely stopped production. Goose's legs are weak and weak, often squat on the ground, the cerumen becomes soft, feeding difficulties, poor growth, joint swelling.

Prevention

(l) Normal amounts of mineral additives are added to the feed to provide sufficient green fodder.

(2) More than the sun, the lighting time per day must not be less than 6 hours.

(3) intramuscular injection of vitamin A, D.

(4) Feed cod liver oil, 1 or 2 times a day, in order to speed up the treatment, you can feed vitamin D3, taking 150,000 international units at a time.

(5) Waste sugar (molasses) fed sugar cane sugar seeds: When it is found that egg geese have metabolized soft shell eggs, they should immediately mix 5% of the waste sugar in the feed, or increase it for every 50 kg of drinking water. Five kilograms of waste sugar were fed to the geese after dissolution. After 7 days, the geese had normal egg production. This is due to the addition of a large amount of sugar in the waste sugar, as well as a variety of vitamins, calcium, phosphorus, yeast, not only helps to increase the appetite of the goose, but also added the required vitamin D, calcium, phosphorus in the goose, also increased The high-calorie sugar content meets the needs of egg geese for various nutrients, and at the same time enhances the cold-resistance ability, thus achieving the effect of curing soft shell eggs of geese.

In the case where it is difficult to determine the cause of the disease, a treatment diagnosis can be carried out. After the diseased geese are fed with anthelmintic drugs, if the condition is improved, it is caused by the infection of parasites, otherwise it is a metabolic disease.
