Feeding management of ostrich breeding period
Female ostriches in captivity are generally mature at the age of 2 to 3 years. Less eggs are produced in the first year, generally 20-40 pieces, and then increase year by year. When it reaches 7 years old, it reaches the peak of egg production, reaching about 80-100 pieces, and the effective breeding period is 40-50 years. Male ostrich sexual maturity slightly later than female ostrich, so pay attention to the introduction, male ostrich must be more than six months or one year old female ostrich, in order to achieve a more ideal reproductive effect. Female ostriches start egg production every March-April and continue until September. The length of its duration is affected by food, climate and its own conditions. In natural conditions, at the beginning of the breeding season, a male ostrich carrying 2-3 female ostriches (commonly known as "one wife, two hens") forms a unit and moves alone. When male and female ostriches courtship, they will make beautiful moves and show off their feathers. The mating time is about 30 seconds to 1 minute. Male ostriches usually mate 4-6 times a day, but also have strong sexual desire up to 8 times. Female ostriches lay their eggs very soon after mating. They usually produce 1 egg every other day, usually producing 12-16 eggs and begin to hatch naturally. In order to allow female ostriches to hatch more eggs, eggs can be removed after the ostriches produce eggs, so that eggs can be laid continuously during the entire breeding season, and the male ostriches should be prevented from attacking when taking eggs. Insufficient food supply, female ostriches produce fewer eggs, body condition is too fat, reproductive performance is poor, and there are no more lean eggs. Usually 12 to 20 breaks for a week, and then begin the next laying cycle, but high-yield ostriches can produce 40 consecutive breaks. Mainly related to feeding management. Low-yield ostriches and older ostrich eggs have almost no regularity. Normal fertilization rate is 60%-85%
