Abstract

The invention discloses a purely natural egg yolk colorant and the application thereof, which belongs to the technical field of feed additive. The colorant is characterized in that chili coarse powder with 60-80 meshes and chemical agents are mixed and crushed with the weight proportion of 4-6%, thereby obtaining the egg yolk colorant. When in use, 1-10 grams of the egg yolk colorant is added into every 1,000 grams of basic ration, thereby obtaining a powdery feed which is used for laying hens and is rich in capsanthin. The effects and advantages of the colorant are: optimal addition of the egg yolk colorant used in the laying hens feed is that 8 grams of the egg yolk colorant is added into every 1,000 grams of basic ration, the price is low, the raw material source is stable; the color of the egg yolk is obviously improved, the chroma of the egg yolk (in Roche colorimetry) can be higher than 13 with permanent stability; the productivity of laying hens is improved, the average weight of an egg is increased by 8.48%; the colorant increases the utilization rate of feed, has no bad effect on the palatability of the feed and has no toxic and side effect.

Description

A kind of pure natural yolk colorant and application thereof
Technical field
The invention belongs to field of feed additive technology, relate to a kind of pure natural yolk colorant, significantly improve the plant type yolk colorant of egg redness degree, laying hen production performance and egg product matter.
Background technology
Along with the scale of aviculture, intensification make that the mode of raising scattered can not extensive use, the shallow partially problem of cage bird yolk ubiquity color and luster, it directly has influence on the economic benefit of laying hen production.Extra interpolation yellow and pink group carrotene become the method that extensively adopts in the feed industry in egg feedstuff.Seed feed commonly used all can not satisfy chicken to Pigmented needs as the lutein content of wheat, soybean and corn etc.The feed value of capsicum mainly is as the natural colouring matter source, deepens yolk color; Also contain certain nutrition simultaneously, can be used as the feed nutrition hardening agent, to promoting the good effect of growing of livestock and poultry.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of pure natural yolk colorant and application process thereof, this yolk colorant uses in the cycle at layer breeding as feed addictive, significantly improve yolk color, improve laying hen production performance and egg product matter, and improve efficiency of feed utilization.
Technical scheme of the present invention is as follows: the mass ratio of 60~80 order pimiento meal and chemical assistant is 4~6%; Usually use pimiento meal 200~300g and chemical assistant 8~15g, after mixing is pulverized, get yolk colorant.Prepare egg feedstuff in the ratio that adds 1~10g yolk colorant in every 1000g basal diet.
Effect of the present invention and benefit are: use in egg feedstuff as yolk colorant (1), and optimum addition is the yolk colorant that adds 6~10g in every 1000g basal diet, and is cheap, raw materials enjoy stable sources; (2) obviously improve yolk color, yolk colourity can reach more than 13, and the colourity lasting stability; (3) improve the laying hen production performance, the egg average egg weight has improved 8.48%; (4) improve efficiency of feed utilization, the palatability of feed is not had any harmful effect; (5) without any side effects; (6) production technology of the present invention is simple, and is easy to use.
The specific embodiment:
Be described in detail specific embodiments of the invention below in conjunction with technical scheme.
Get 300 purpose yolk colorants, the ratio in adding 1~10g in every 1000g basal diet mixes in mixer, as supplying the examination feed.
The 5-6 month in 2008,, carry out yolk colorant feeding experiment of the present invention at ditch willow man of Daliang City Dong family chicken house.Select 120 the 30 blue brown laying hens in sea in age in week for use, be divided into 4 groups at random, establish 3 repetitions for every group, each repeats 10 chickens.30 days experimental periods,, first week was preliminary trial period, the unified basal diet of feeding; 8~22d test group is fed and is contained the feed of yolk colorant, and 23~30d stops feeding for the examination feed, the unified basal diet of feeding.Re-using Luo Shi colorimetric fan analyzes yolk color, measures egg size with assay balance.
Experiment shows, uses in the cycle at layer breeding, compares with control group, and average egg weight has improved 8.48%; Laying rate improves 5.52%; Feed intake descends 1.66%, and feedstuff-egg ratio has descended 9.55%; Average yelk bepaint index (RYCF) has improved 31.16% (seeing Table 1).Pigment availability height, deposition effect is stable, and yolk color (RYCF) can reach 13.65, stops feeding still can keep more than 9 after 8 days (to see Table 2).
Table 1. uses behind the feed contain yolk colorant of the present invention the influence to egg size, laying rate, feed intake and feedstuff-egg ratio
