METHOD FOR BREEDING BUSTARD OTIS TARDA Russian patent published in 2022 - IPC A01K67/00 

FIELD: biotechnology.

SUBSTANCE: invention constitutes a method for breeding bustards (Otis tarda), including the selection of sexually mature groups of birds to form the breeding stock, feeding the birds daily with a mixture of plant-based and animal feeds, organising the mating of the birds, the females laying eggs and hatching them in the nest until chicks are hatched, or the eggs being artificially incubated in incubators, or under hatching females of other bird species, followed by rearing the hatched chicks. In order to implement the reproductive potential and successfully organise the mating in the winter and summer keeping of the birds in enclosures, a male bustard needs to have eye contact with the females. In order to stimulate a female bustard refusing to hatch to incubate, her eggs in the nest are replaced with fakes made of coloured goose eggs imitating bustard eggs, and when the female feels comfortable hatching the fakes and the incubation mode nears to normal: the female bustard sits on eggs all night and for the most of the daylight hours, gets up only for feeding, for a short walk and to protect the nest, then the fake eggs in the nest are replaced with bustard eggs. In the rearing period of the young stock over 3 months of age, the birds are fed 3 times a day with different types of feed containing a dry grain mixture; wet bulk mash; fresh vegetables: pumpkin, squash, beetroot, cabbage; fresh meat or mice; black chokeberry and/or currant berries, and/or grapes; fresh or, in winter, hydroponic greens, with the following ratio of components of the feed per day: the diet of an adult male is twice the diet of an adult female. In the first days after hatching, the young stock are given, alternately: several drops of water, 3 to 4 grains of sand about 2 mm in diameter, small pieces of hard-boiled eggs, several recently moulted mealworms or chafers, curd, with a feeding frequency of 12 to 15 times in 2 to 3 g portions of feed in the first 1 to 3 days after hatching; from the 3rd day, finely chopped tender green lettuce poured over with water, small insects, or soft body parts of large Acridoidea are added to the diet of the young stock, then ingredients from the diet of adult bustards are gradually added to the diet, such as steamed cereals, boiled meat, boiled fish, vegetables, greens, fresh meat, young mice, combining the feeding of fresh meat, mice, and mealworms with simultaneous feeding of fresh greens to appetite. By the age of one month, the frequency of feeding the young stock is reduced to 4 times a day, and feed portions are increased. By the age of three months, the young stock are put on the diet of adult birds. In the summer period (June to September), in addition to mass-produced feeds such as grain mixture and wet mash, various field-caught arthropods are introduced into the diet of the young stock, promoting the additional exercise and development of the chicks, facilitating the adaptation of birds on their reintroduction into nature.

EFFECT: invention raises the efficiency of bustard breeding and provides the possibility of managing bustard breeding.
