Nutritional needs and compound feed
Geese need to consume more nutrients, especially energy, protein, calcium, phosphorus, etc. due to continuous egg production and reproduction. Therefore, the level of feed nutrition and whether it is balanced have a direct impact on the production performance of the mother goose. The geese began to feed egg-laying feeds about 20 days prior to laying eggs. As China's geese are mainly raised extensively, the southern part is mainly grazing, and the feeding of rations is only a supplement. Therefore, according to the local feed resources and geese in the growth and production stages of nutritional requirements in accordance with local conditions to design feed formulations.
Under the condition of feeding mainly, it is recommended that the dietary nutrition level of the laying goose is metabolic energy 10.88 kJ ~ 12.3 kJ/kg, crude protein 14% ~ 16%, crude fiber 5% ~ 8% (not high At 10%), lysine 0.8%, methionine 0.35%, cystine 0.27%, calcium 2.25%, available phosphorus 0.3%, table salt 0.5%. According to the experiment, the geese were fed with a formulated feed prepared at a ratio of 40% of corn, 12% of soybean cake, 25% of rice bran, 5% of rapeseed cake, 1% of bone meal, and 7% of shell powder. The average egg production and fertilized eggs were used. Fertilization rates of egg and egg were respectively increased by 3.1%, 3.5% and 2% compared with single rice.
In addition, domestic and foreign geese production practices and trials have proven that female goose feeding on green and juicy feed has a good impact on improving reproductive performance of female geese. Therefore, where conditions permit, more green feed should be fed during the breeding season.
The feed is generally fed with 150 g to 200 g of supplements per day, and fed three times, one at night and one at the end of the egg production.
Drinking water
Breeding and metabolism of geese requires a large amount of water, so it is necessary to provide sufficient drinking water for geese. Always keep clean drinking water inside. Egg-laying geese drink as much water at night as they do during the day, so they need to drink enough water at night to meet the water requirements of the goose body. Environmental Management
Creating a good living environment for geese and careful management are the basic conditions for guaranteeing high yields and stable production of geese.
Suitable ambient temperature. The physiological characteristics of the goose are: plump and plump, with more velvet feathers; subcutaneous fat and no sebaceous glands, only developed tail fat glands, heat dissipation difficulties, so cold and not heat, sensitive to high temperature reactions. In summer, the temperature is high, and the goose often stops production. The male goose sperm is not active. In the management of egg-laying geese, attention should be paid to the ambient temperature, especially in summer heat-stroke cooling work.
Appropriate lighting time. The length and intensity of the illumination time have a great influence on the breeding ability of breeding geese. Adding light to the geese can increase egg production at a suitable ambient temperature. The use of natural light plus artificial light should be no less than 15 hours per day, usually 16 hours to 17 hours, until the end of egg production. At present, most of the breeding of many kinds of geese adopts open goose house and natural light system. The lack of illumination time has a certain impact on the production of eggs. Therefore, in order to increase the egg production rate, light should be supplemented, and generally it is better to start one month before the start of production, from less to more, until a suitable illumination time is reached. The time for adding artificial lighting is arranged in the morning and evening respectively. Different species need different lighting conditions in different seasons, according to the season, region, species, natural lighting and age of egg production, the development of lighting plan, according to the plan, can not be arbitrarily adjusted.
Feeding geese can supplement light sources when there is insufficient sunlight. The light source intensity is 2 watts to 3 watts per square meter. It is better to install one 40 watt to 60 watt bulb per 20 square meters, and the distance between the lamp and the ground is 1.75. Meters around.
Reasonable ventilation. As the geese during the laying period are reduced by grazing, they live longer in the goose house and have a lot of food intake and excretion. This will make the air inside the house dirty and reduce oxygen, which will not only affect the health of the goose, but also reduce the production of eggs. In order to maintain fresh air in the geese, in addition to controlling the rearing density (1.3 to 1.6 birds per square meter, 2 animals per square meter under grazing conditions), timely removal of excrement and bedding, the doors and windows must be frequently ventilated.
