During the breeding process of ducks and ducks, the sudden drop in egg production and the low egg production rate occur frequently, resulting in huge losses to the duck farmers. The main reasons are as follows.
1, feeding and management
1.1 The feeding method is unreasonable. Due to the persistently depressed market prices, most of the duck farmers are in a loss state. To reduce the breeding cost, self-made feeds or duck feeds from multiple manufacturers are often used; some farmers are The use of ducks in different egg-laying periods (such as the initial production and the peak egg-feeding ducks) is mixed; even direct feeding of ducks and ducks with pig feeds can hardly guarantee nutrient requirements for normal production of ducks and ducks, leading to the constitution of duck-duck. Too weak, resistance decreased, egg production decreased.
1.2 Poor feed quality and unbalanced nutrition. Some small feed mills are not very good in terms of technical strength, testing methods, or raw material checks. The quality of their products cannot be effectively guaranteed. After laying ducks feed on these inferior feeds, Easy to cause thin and wet ducks, wet hair, off feathers, low disease resistance, egg production decreased, it is difficult to return to normal levels in a short time.
1.3 extensive management, excessive breeding density, poor sanitary conditions, duck house damp, poor ventilation, indoor ammonia concentration is too high, poor ranch water quality, decreased feed intake can cause decreased egg production.
1.4 Illumination is unreasonable. Excessive light or lack of light is one of the important factors affecting the production efficiency of ducks. The light is too strong for ducks, which can easily cause spasms, irritability, and misshapen eggs. Insufficient light can make drinking water available. The decrease of feed intake will affect the increase of egg production rate.
1.5 Stress factors. Mutation of the climate, thunderstorms, hot and cold stimuli, vaccination, stranger or animal startle, feed or keeper replacement, etc., can reduce egg production.
1.6 Nutrition. Ritual amino acid imbalance, lack of sulfur-containing amino acids, lack of minerals, vitamins, electrolytes, calcium and phosphorus imbalance is an important factor in the decline in egg production.
1.7 medication. Sulfa drugs, streptomycin have an effect on the production of eggs, clinical medication should be cautious.
2, disease factors
2.1 viral disease. Egg drop syndrome, caused by adenovirus, its clinical features is a sudden drop in duck egg production, a large number of soft shell eggs and deformed eggs, the common color becomes lighter.
2.2 bacterial diseases. E. coli infection caused by fallopian tube inflammation, resulting in reduced egg production. Salmonella, Pasteurella multocida, mycoplasma infection caused by tubal inflammation or atrophy, making egg production decreased.
2.3 Parasitic diseases. Coccidia, nematodes, aphids, and ectoparasite infections make ducks weaker in body constitution, lower disease resistance, poor appetite, and lower egg production rate.
2.4 Moldy feed poisoning. Aflatoxin poisoning can inhibit the development of the thymus and the bursa of Fabricius, reduce the body's resistance, affect the egg production of ducks, resulting in the short term can not be restored to normal levels.
3, prevention measures
3.1 to strengthen feeding and management. Improve the feeding environment, do a good job of environmental sanitation, regular disinfection, housing feces should be promptly cleaned up, maintain a suitable breeding density, strengthen ventilation and warm, reasonable adjustment of light intensity and light distribution.
3.2 Reducing stress factors. Feed replacement, vaccine injection, and sudden weather changes should increase the supply of electrolysis multidimensional and probiotics to minimize the adverse effects of stress factors.
3.3 Strengthen nutrition and feed high-quality full-price diets. When the duck population appears to be decease, the amount of egg production should be reduced in time to supplement nutrition, increase the use of vitamins, minerals, electrolytes, and sulfur-containing amino acids, and increase the protein in the feed. Level, supplement the cod liver oil, etc., in order to enhance the egg duck physique, increase egg production.
3.4 attention to disease prevention and control. Regular deworming, prenatal injection of egg drop syndrome vaccine; when the duck population has an epidemic disease, the diseased duck should be promptly isolated treatment, the threatened duck group feeding preventive drugs in the prevention and treatment Medications should avoid the use of drugs that can cause decreased egg production, such as sulfonamides.
3.5 Other measures: To adjust the normal flora in the body, reduce the ammonia concentration in the house, improve water quality, reduce the spread of the disease, and have a positive effect on the recovery of egg production.
