Problems solved by technology

[0004] When the brown horse chicken is not nutritious when laying eggs, the specific gravity of the brown horse egg will be low, the gap in the eggshell will be large and not full, the calcium content in the brown horse chicken will be insufficient, and the calcium content of the brown horse egg will be insufficient. The shell is thin, which will affect the hatching rate and survival rate of brown eared pheasant in severe cases

Embodiment 1

[0070] In this embodiment, taking brown-eared pheasant breeding in Taiyuan Zoo over the years as an example, the effects of poultry granules and rice corn bread in the feed formula of the present invention are illustrated through the feeding methods over the years and the changes in the hatching rate and survival rate of brown-eared pheasants.

[0071] In 2013, Taiyuan Zoo adopted conventional artificial machine hatching and artificial brooding methods, and fed ordinary poultry feed. As a result, the probability of brown-eared pheasant hatching failure was more than 90%, and almost none survived. Since 2014, brown horse eggs have been hatched by taking out the breeding eggs for storage and foster relatives, and the method of enriching brown-eared pheasants has been continuously improved. Since 2015, poultry pellets and rice cornbread have been used to replace traditional poultry feed, and the formula of poultry pellets and rice cornbread for brown eared pheasants has been conti...

Embodiment 2

[0083] In this example, on the basis of Example 1, the feeding and management of brown eared pheasants is carried out using the feed formula finally optimized, and at the same time, many measures such as other sites, breeding egg maintenance, hatching, and small brown eared pheasant management are carried out. Optimized.

[0084] In the past, brown-eared pheasant breeders in Taiyuan Zoo used boiled and mashed eggs to feed brown-eared pheasants during the breeding period, intending to supplement protein. However, brown-eared pheasants often eat their own eggs in the later stage, so the brown-eared pheasant feed was canceled. Add eggs. In 2017, Taiyuan Zoo added silkworms and mulberry leaves to the diet of brown-eared pheasants during the breeding season, respectively replacing mealworms and rapeseed in the feed formula in 2016, aiming to supplement the protein, vitamins and trace elements in brown-eared pheasants and reduce brown Egg-eating risk of horse chickens, improving th...

Abstract

The present invention discloses a feed and breeding method for improving egg production and hatching rate of crossoptilon mantchuricum. A daily feed formula of the crossoptilon mantchuricum is optimized. Mulberry leaves are added in a feed used in an estrus period and egg production period of the crossoptilon mantchuricum, and young silkworms are used to replace tenebrio molitor, so that protein and fatty acid of the feed are enriched. The feed provides high-quality nutrients for the crossoptilon mantchuricum in the egg production period, especially sufficient trace elements, vitamins and calcium, supplement of extra eggs is not needed for the crossoptilon mantchuricum, and a risk of the crossoptilon mantchuricum eating own eggs after egg production is reduced. The provided method scientifically manages the crossoptilon mantchuricum according to habits of the crossoptilon mantchuricum, simulates wild life of the crossoptilon mantchuricum to the greatest extent, and adopts various waysto enrich and increase sense of security of the crossoptilon mantchuricum, and reduce stress behaviors. The method for artificially feeding the crossoptilon mantchuricum is established and by simulating the wild life and enriching feed nutrition of the crossoptilon mantchuricum, the hatching rate of the crossoptilon mantchuricum is finally improved by about 10%.

Description

technical field [0001] The invention relates to the field of domestication of wild animals, in particular to a feed and a feeding method for improving the egg production and hatching rate of brown-eared chickens. Background technique [0002] Brown-eared pheasant, which belongs to the genus Horse-pheasant of Galliformes Phasianidae, also known as black pheasant, horned pheasant, and pheasant, is a rare wild bird unique to China. The brown-eared pheasant is a national first-level key protected wild animal and is listed as a vulnerable species by the IUCN Red List. [0003] The problem of low reproductive rate of artificially raised brown-eared pheasants at home and abroad may be due to the extensive breeding of brown-eared pheasants, single feed, and improper nutrient ratio, which lead to poor growth of brown-eared pheasants, low egg fertilization rate, and low reproduction rate. rate drops. In particular, after several generations of breeding, brown eared pheasants raised ...
