The early age of early-matching ducks has a premature age, which not only has adverse effects on their own growth and development, but also has a low fertilization rate. General egg-type ducks are sexually mature earlier, and the first-age ducks are suitable for more than 5 months of age. The meat-type ducks have a more mature sex, and the first age is more than 6 months. Ducks are generally about 1 year old and have a strong libido and strong breeding ability. At this time, the proportion of the duck population can be reduced. The matching performance of ducks with males and females varies greatly depending on the type of duck. Generally, the appropriate ratio of males to females is 1:20 to 1:25 for egg-type ducks, 1:15 to 1:20 for ducks for combined use, and 1:5 to 1:8 for meat-type ducks. Seasonal factors The cold weather in early spring affects the sexual activity of ducks. The proportion of male ducks should be increased by about 2% (based on the number of female ducks). Feeding and management Under good husbandry conditions, especially for grazing ducks, due to the availability of rich animal feed, breeding performance is enhanced. Therefore, the proportion of male ducks can be reduced appropriately. When the male and female gregarious time comes before the breeding season, appropriate early gregary can increase the fertilization rate of female ducks. The proportion of male ducks at the beginning of the gregarious period may be slightly higher. For example, the male to female ratio for egg-type ducks may be 1:14 to 1:16; after 20 days, it may be changed to 1:25. When a large group of ducks are mated, it is often seen that part of the male ducks do not disperse in the mother duck group for a longer period of time, and it takes more than 10 days to mate. Therefore, the male duck should be put into the mother duck group as early as possible in large group breeding. Digital 60m short range laser rangefinder is a laser measurement device which is supposed to replace tape measure, ruler, and other traditional length meauring tool.
