Embodiment 1

[0028] For a bustard aged 90-450 days, the feed ingredients are: 30 parts of corn bread, 200 parts of meat food, 40 parts of eggs, 20 parts of fruits and vegetables, 2 parts of vitamins, 0.2 parts of trace elements, 2 parts of bone meal, calcium tablets 2 parts, 1 part cod liver oil, 0.5 part salt.

Embodiment 2

[0030] For bustards over 450 days old, the feed ingredients are: 40 portions of corn bread, 220 portions of meat, 40 portions of eggs, and 30 portions of fruits and vegetables.

[0031] Table 1 is the daily average nutritional requirement of bustard during the growing period, and Table 2 is the comparison of several commercially available feed formulas and the formula of the application feed on the daily weight gain of the bustard during the growing period. It can be seen that the formula of the application feed is adopted, and the feed utilization rate is 99%, the increase in daily weight gain is 23%, the ratio of the number of diseased individuals to the total number of cultured individuals is 0%, the feed utilization rate of the feed of this application and the increase in daily weight gain are much higher than other formulas, and the number of diseased individuals is higher than the total number of cultured individuals The ratio is 0%, much lower than other formulations.

Abstract

The invention discloses feedstuff for a rearing stage of bustards and other large-sized birds. The feedstuff is characterized by comprising the following ingredients in parts by mass: 30-40 parts of steamed corn bread, 200-220 parts of meat food, 40 parts of hen's eggs and 20-30 parts of fruits and vegetables. After a brooding stage ends up, growth and development of the bustards and other large-sized birds enter a relative slow rearing stage, needs of the bustards and other large-sized birds on physiological development should be met, and too-fast increase of body weight of the bustards and other large-sized birds should also be controlled; and the feedstuff for the rearing stage of the bustards and other large-sized birds, disclosed by the invention, is quantitatively fed according to different ages in days, so that the bustards at the rearing stage can be in line with standards in body weight and have sufficient energy and nutrient backup.

Description

technical field [0001] The invention relates to the field of artificial breeding of large birds, in particular to a feed for bustards and other large birds in the breeding period. Background technique [0002] The great bustard (Otis tarda) belongs to the bustard family (Otidae) of the order Gruiformes, and is commonly known as ground 鵏, sheep 鵏 (male bird), chicken 鵏(female bird), and often lives on grasslands and desert grasslands. It is a typical Indicator species of grassland birds and grassland ecology. It is classified as VU (Vulnerable) by IUCN (BirdLife International, 2013). my country has listed it as a national first-class key protected species. China's Red Book ranks it as a V-level species, which is a globally threatened species. [0003] The great bustard is a representative species of clean grasslands. At the beginning of the 20th century, it was widely distributed in grasslands, forest grasslands and semi-desert areas of Eurasia. However, with the increase ...
