1. Breeding period
(1) Feeding methods The daily activities of ostriches raised by hand are more regular. Therefore, feeding should be done regularly and quantitatively according to the rules of life. Every morning when the sky shines, the ostriches run around the nets on the sports grounds and mate and feed after 1520 minutes. Therefore, the first feeding time is from 6:30 to 7:30. Feed 4 times a day. The intervals of each feeding are as equal as possible. The feeding sequence can be followed by coarsening and finishing, and the concentrate can also be fed together with green feed. The amount of concentrate feed is generally controlled at about 1.5 kg each to prevent over-fertilization resulting in decreased egg production or discontinuation of production.
(2) Feed and Nutrition The average protein content in compound feed for ostriches during the egg production period is 18%, and metabolic energy is 10,5 MJ/kg. Green feed is mainly free-feeding. Special attention should be paid to the intake of calcium by the breeding birds. In addition to sufficient calcium and phosphorus in the feed, a food trough fed with bone meal can be set in the pens, and any type of ostrich can freely feed.
2. Egg production management
(1) Female ostriches reach sexual maturity at 2430 months of age, and male ostriches reach sexual maturity at 36 months of age. Before sexual maturation, they were reared in large groups of 2030 individuals and their spouses were grouped 1 month before laying. Usually 4 (1 male and 3 female) are a feeding unit. The grouping work is usually carried out in the evening. The female ostriches are first introduced into the aviary, and then the males are introduced. This can reduce the disparity between males and females and between populations.
(2) The size of the ostrich in the sports ground is large, and the area of ​​the sports field required is also correspondingly large. A feeding unit (1 male and 3 female) takes about 1,500 square meters. This will give ostriches a relatively free range of activities, which will help increase the fertility rate and prevent over-fertilization. Ostriches are generally free and do not need to drive away. If the breeding herd is larger, 7 or more than 14 are a breeding unit, then it is necessary to drive out the sport. It is best to drive 12 hours each morning and in the afternoon.
The stadium must maintain good sanitation. Remove feces and debris from the stadium at any time. Do not place debris around the bird bar and the trough so as to avoid eating hard foreign bodies, leading to obstruction of the stomach and perforation of the intestines, resulting in extreme death. It is best to disinfect the playground and sheds once a week.
(3) Resting production In order to maintain the excellent egg production performance of female ostriches and extend their useful life, mandatory production is required. It is generally held in the period from November to January of the following year. At the beginning of the abortion period, the male and female birds were reared separately, and the breeding was stopped. The female angels of the five angels stopped feeding and stopped laying, and then fed the perinatal period feed.
(4) Take care when you want to change the playing field or sell ostriches that need to be caught. Because the ostrich skull is very thin and spongy, the connection between the head and neck is also relatively fragile and can not withstand the impact. One day before catching, feed in the shed, and when it is ingested, close it in the shed. When capturing, 34 people need to cooperate. Hold the neck and wing feathers, hold the chest, and put a black hood on the head. Make it stable. Once the ostrich has put on the hood and blindfolded it, it will be able to hold the cage and load it. However, special attention must be paid to ferocious ostriches, and some sedative drugs should be given in the first 34 hours before capture.
(5) Before transporting ostriches, transportation must be stopped and the production must be stopped. Ensure that there are no mature eggs in the fallopian tubes during transportation. The feed was stopped 34 hours before transportation and vitamin C, salt, and sedatives were added to drinking water to prevent stress reactions. The autumn, winter and spring seasons are suitable for the transportation season. It is best to choose to perform at night. Because ostriches cannot see the outside scenery, they can reduce the disturbance. Transport tools and cages are to be sterilized, and the cages are required to be sturdy and ventilated, with black fences on top. Observe the dynamics of ostriches at any time during transportation and pay attention to regular water supply for long-distance transportation. Keep the interior of the car well ventilated and wear a black hood on the restless ostrich. Due to stress, the delivered ostrich often showed a decline in appetite and a granular appearance in 13 days. Vitamins and electrolytes should be added in a timely manner, and feed should be fed gradually to facilitate the recovery of ostrich transportation after stress.
