Description

Special compound premix feed for green-shell laying hens in egg producing period and preparation method thereof Technical Field The invention belongs to the technical field of breeding feeds, and particularly relates to a special compound premix feed for green-shell laying hens in an egg producing period. Background The green-shell layer takes the green eggs with high nutritive value as the core characteristic, and common varieties are Dongxiang black-feather green-shell layer, thre green-shell layer, lushi green-shell layer, changshun green-shell layer, shendan No. 6 green-shell layer and the like. Compared with common eggs, the green shell eggs are rich in lecithin, vitamin A, vitamin E, zinc, iodine, selenium and other microelements, and simultaneously contain rich amino acids, especially lysine, aspartic acid, glutamic acid and the like, and in addition, the green shell eggs have lower cholesterol content, so that the green shell eggs more meet the requirements of people on healthy diet. However, the green-shell layer chicken has the characteristics of lively and active and easy-to-fry groups, and is easy to cause intestinal problems, so that the management is difficult and the laying rate fluctuates greatly, thereby increasing the breeding cost and reducing the final income. In addition, the green-shell egg consumers have higher attention to the color of eggshells, but the color of eggshells of the green-shell eggs quickly lightens after the peak period of laying eggs (after 40 weeks of age), and the market selling value of eggs is seriously influenced. At present, the solution to the eggshell color problem is mainly focused on brown-shell laying hens, namely, additionally supplementing porphyrin iron to provide protoporphyrin which is a main component of eggshell pigment, and using nutrients, chinese herbal medicines, polysaccharide substances and the like with blood replenishing function to promote the health of organisms and pigment synthesis so as to improve the eggshell color. However, unlike brown-shell layers, the eggshell pigment of green-shell layers is mainly composed of biliverdin IX and zinc chelate of biliverdin, and is 2 times that of protoporphyrin, and the pigment metabolic pathway is also significantly different from that of brown-shell layers. In addition, the lightening of eggshells of the green-shell laying hens in the later period of laying eggs is mainly related to the aging of organisms, and comprises the steps of increasing the methylation rate of genes and reducing the expression level of related genes, so that the metabolic production of pigments is changed. In view of the above, there is a need to solve the problems of easy frying groups of green-shell layer chicken and light eggshell color in the later period of laying eggs. Disclosure of Invention The invention provides a compound premix feed (hereinafter referred to as premix) suitable for a green-shell layer chicken in an egg producing period, which can improve the anti-stress capability of a chicken flock, improve the stability of the flock, solve the problem of easy frying of the flock, delay the aging of the layer chicken, improve the production performance and the egg quality of the green-shell layer chicken in the egg producing period, further improve the eggshell color for a long time and improve the market value of products. The invention adopts the following technical scheme to solve the above-mentioned problems: In a first aspect, the invention provides a special compound premix feed for green-shell laying hens in an egg producing period, which comprises the following components in parts by weight: 10.0 to 20.0 parts by weight of green tea, 10.0 To 20.0 parts by weight of nucleotide residues, 15.0 To 25.0 parts by weight of calcium hydrophosphate, 15.0 To 30.0 parts by weight of stone powder, 0.5 To 1.0 weight portion of soybean lecithin oil, 5.0 To 8.0 parts by weight of sodium chloride, 2.0 To 8.0 parts by weight of heme protein powder, 0.5 To 2.0 parts by weight of taurine, 0.5 To 3.0 parts by weight of choline chloride, 0.5 To 2.0 parts by weight of turmeric, 0.2 To 1.0 weight parts of enzyme preparation, 0.2 To 1.0 weight parts of phytase, 0.2 To 0.8 weight portion of oregano fragrant phenol, 2.5 To 4.0 parts by weight of DL-methionine, 2.0 To 5.0 parts by weight of amino acid composite package, 2.8 To 3.2 parts by weight of microelement premix, 0.5 To 2.0 parts by weight of organic mineral composite bag, 0.6 To 0.8 weight portion of vitamin premix, 0.1 To 0.5 weight portion of vitamin C, 0.02-0.15 Parts by weight of vitamin E, 0.2-0.4 Parts by weight of an antioxidant. As a specific embodiment of the invention, the compound premix feed consists of the following components in parts by weight: 10.0 to 15.0 parts by weight of green tea, 15.0 To 20.0 parts by weight of nucleotide residues, 15.0 To 25.0 parts by weight of calcium hydrophosphate, 15.0 To 30.0 parts by weight of stone powder, 0.5 To 0.8 weight por
