Duck habits to adapt to different habits day and night

The duck's living environment alternates day and night. Affected by this, some of the duck's habits also have a corresponding circadian change pattern. To comply with this pattern of change, do a good job of feeding and management of ducks to obtain better economic benefits. First, the law of diurnal variation of ducks' intake. Under natural light, the ducks have 3 ornithals in one night, respectively, in the morning, at noon, and in the evening. According to another report, under intensive farming conditions, in order to fast fatten the Muscovy ducks, they were exposed to light for 24 hours. As a result, there were two peaks and two troughs. The former was at 18-22 and 22-24. At 2-6 and 10-14. Feeding management: (1) Strengthen early feeding. The appetite of the duck group is particularly strong at dawn. At this time, feeding and feeding can make the duck increase its long flesh. (2) timing grazing. Grazing should be carried out when the duck eats peaks in the early, middle, and late times. The rest of the time allows the ducks to rest or to drive them into the water. (3) Feeding meat ducks under continuous light for 24 hours should use two peaks as the key feeding period and only a small amount of feed during the low season. For drinking or feeding, it is best to schedule the duck during the peak period of feeding. Second, ducks, eggs, day and night changes in the law According to reports, ducks eggs are mainly concentrated in the period from midnight to dawn before this time, usually not in the daytime eggs. Feeding management: (1) Turn off the lights at 10 o'clock at night and stop lighting to ensure that the ducks lay eggs in a quiet environment from 1-4 pm the next day. (2) If it is found that ducks generally produce eggs later than 5 o'clock, and the eggs are small, it indicates that the concentrate in the diet is insufficient, and the fine material should be increased in time according to the standard. (3) If the ducks lay eggs during the day, they are mostly caused by poor feed, lack of nutrition, premature grazing in the morning, or high temperatures in the duck houses and high humidity. Targeted improvements should be made to their feeding and management conditions, and the ducks should be postponed until 8 o'clock each day. Third, the diurnal variation of breeder duck mating It has been reported that mating ducks are generally selected in the morning or evening and are carried out on vast water surfaces. Feeding management: make full use of the peak of the mating ducks in the morning and evening to drive them to deeper waters to increase the fertilization rate of the breeding eggs. Fourth, the circadian rhythm of the disease when the law of day and night sickness is caused by transport stress, because the ducks every day in the afternoon when the incidence of 17-19 was named. During the onset of the disease, the ducks clashed violently and quickly piled up, causing some of the weak ducks to be trampled to death. Mortality rates ranged from 17% to 24%. Feeding management: Minimize the stress of ducks before and after long-distance transportation. Within a few days after the arrival of the duck, anti-stress medications, such as chlorpromazine, are added to the diet 1-2 hours before each day of the day in order to promptly stop outbreaks in the pupa. V. Circadian variation of immune response According to reports, the sensitivity of poultry to immune agents (vaccines, bacterins, etc.) is cyclically changed day and night, daytime sensitivity is poor, immune response is dull; at night close to midnight, the adrenaline in the body The most secreted, immune response is the most sensitive. Feeding management: Immunization of poultry (including ducks, geese, and chickens) works best in the early morning hours. There are two benefits: (1) Poultry stops moving at night, it is easy to catch, and the stress response is small. (2) Vaccination when the immune response of the poultry is sensitive can make it faster and better to produce immunity.
