Premix feed for promoting development of ovary of laying hen

Abstract

The invention discloses a premix feed for promoting development of ovary of a laying hen. The premix feed is prepared from the following components in parts by weight: 150-200 parts of calcium hydrophosphate, 240-300 parts of stone meal, 40-60 parts of table salt, 20-40 parts of sodium sulfate, 15-20 parts of choline, 40-50 parts of compound microelements, 8-10 parts of compound vatimins, 10-20 parts of lysine, 25-30 parts of methionine, 150-250 parts of bone meal and 40 parts of an additive, wherein the additive is prepared from the following raw materials in parts by weight: 10 parts of soy isoflavone, 6 parts of calcium formate, 5 parts of lecithin, 4 parts of probiotics, 3 parts of phytase, 2 parts of an complex enzyme preparation, 1 part of chromium picolinate, 2 parts of VE, 2 parts of VC and 5 parts of Chinese herbal medicines; the Chinese herbal medicines are prepared from the following components in parts by weight: 0.5 part of ligusticum wallichii, 0.5 part of angelica sinensis, 0.5 part of caulis spatholobi, 0.5 part of radix sophorae flavescentis, 0.5 part of elecampane, 0.5 part of radix paeoniae alba, 0.5 part of codonopsis pilosula, 0.5 part of astragalus membranaceus, 0.5 part of acanthopanax and 0.5 part of leonurus. The feed disclosed by the invention is rih in nutrition, so that intake of nutritional ingredients of the laying hen in a special period from 90 days to 130 days, and moreover, the immunity of the laying hen is improved, and the death and culling rate of the lay hen is reduced.

Description

Technical field

[0001] The invention relates to a premixed feed for promoting the ovarian development of laying hens, in particular to a premixed feed for promoting the ovarian development of laying hens (90-130 days old). Background technique

[0002] Laying hens 90-130 days of age are the fastest growing period of ovaries and fallopian tubes. Before 90 days of age, the fallopian tubes are only 10 cm long. After 90 days of age, the fallopian tubes develop rapidly and become thick and large in a short period of time, 80-90 cm long. . The ovary weighs only about 3 grams before 90 days of age, and rapidly increases to about 50-60 grams after 130 days of age. Therefore, during this period, adequate nutrition must be provided so that the hens have sufficient nutrition reserves to meet the rapid growth of ovaries and fallopian tubes.

[0003] However, the existing layer feed lacks special feed for the specific growth period of 90-130 days old layer, and ordinary layer feed cannot meet...
