Abstract
The invention discloses a laying duck special feed for improving yolk color, which is prepared by mixing the following raw materials in parts by weight: 30-35 parts of corn, 20-30 parts of bean pulp, 0-5 parts of palm dregs, 30-40 parts of sub-powder, 0-4 parts of rice bran, 8-10 parts of stone powder, 0.6-1.5 parts of calcium hydrophosphate, 0.30-0.32 part of table salt and 1 part of premixing material. By meticulously matching various raw materials in the special feed, particularly adding certain amount of riboflavin into the premixing material, the invention meets nutrition requirements on energy, protein, amino acid, vitamin, and the like needed by laying duck, strengthens body immunity, improves the laying performance and has bright yellow duck yolk. Compared with other feeds, the laying duck special feed for improving yolk color of the invention can improve the laying rate by 5 percent or so, improve the yolk color grade by 15 percent or so and improve laying duck breeding benefit by 3-5 percent.
Description
Technical field
The present invention relates to a kind of feed, relate in particular to a kind of laying duck special feed that improves yolk color.
Background technology
The egg duck needs the nutritional labeling of multiple balances such as lot of energy, albumen, amino acid in the process of laying eggs, if energy shortage or excessive in the feed, perhaps various essential nutritional labeling imbalances, to directly influence egg duck production performance and body condition, and cause egg laying performance to descend, build is thin partially or overfertilization, immunity degradation, raise benefit decline.At present, disclosed egg duck feed document is a lot, differs from one another, and still, in order to improve production performance, strengthens immunity of organisms, ensures egg product safety, improves raiser's economic benefit, and improve egg duck feed is an immortal problem with suiting measures to local conditions.
The egg duck is an aquatic bird, mainly puts in a suitable place to breed over the past thousands of years at southern water area, and by predation fishes and shrimps, pasture and water life, the duck's egg delicate mouthfeel, the yolk Chinese red gives off a strong fragrance.Along with Developing of Animal Industry, egg duck large-scale cultivation engenders also that at northern area the egg duck has also become stable breeding by southern putting in a suitable place to breed, and feed has also become mixed feed by fishes and shrimps, pasture and water.It is yellowish that these variations have directly caused the variation, particularly yolk of duck's egg quality to be become by dried tangerine peel, and yolk color is no longer so tempting.Under existing raising condition, how to improve production performance, improve the duck's egg quality, particularly improve yolk color and just become an important research project, the regulation and control of feed nutrition are key technologies wherein.
The feed addictive that improves yolk color has multiple, as natural colorant marigold, marine alga, pimiento, yellow maize etc., chemical synthesis colouring agent lutein, capsanthin, astaxanthin etc. is arranged also.But the content of pigment in natural colorant is less, the extraction cost height.Though the chemical synthesis colouring agent is safety, stable in certain amount ranges, consumption is excessive, and most meetings produce harmful effect.And along with of the expansion of egg duck in northern stable breeding scale, people recognize gradually that also the duck's egg majority with Chinese red yolk is the cause of having added colouring agent in feed, so for the food security of duck's egg, increasing people no longer pursues yolk when eating duck's egg color is Chinese red.Even now, people wish that still the Ovum Anas domestica yolk color is bright orange rather than yellowish.
The present invention is according to the nutrition principle, adopt feeding experiment, metabolic test and laboratory to detect the method that combines, filter out and to improve production performance, improve the duck's egg quality, particularly improve the laying duck special feed of yolk color, the egg duck laying rate ratio that scale is raised is put in a suitable place to breed and is improved about 5%, duck's egg nutritionally and put no significant difference in a suitable place to breed, yolk color is glassy yellow, color grade is than the duck's egg raising about 15% of other stable breedings.Contain in the special feed more than the riboflavin 30mg/kg, do not contain any chemical synthesis colouring agent, the duck's egg edible safety.
Summary of the invention
The purpose of this invention is to provide a kind of laying duck special feed that improves yolk color,, make yolk be glassy yellow, improve egg duck laying rate, strengthen immunity of organisms, improve and support the duck economic benefit to improve yolk color.
Technical scheme of the present invention is: a kind of laying duck special feed that improves yolk color, it is characterized in that, be mixed and made into by following raw materials according by weight: corn 30-35, dregs of beans 20-30, palm kernel meal 0-5, inferior powder 30-40, rice bran 0-4, stone flour 8-10, calcium monohydrogen phosphate 0.6-1.5, salt 0.30-0.32 and premix 1.
Wherein, described premix is to be fit to the premix product that the egg duck is raised, riboflavin content 〉=3000mg/kg in the premix.
From improving the effect of yolk color and raising laying rate, its optimum weight proportioning is: corn 30, dregs of beans 22, inferior powder 38, stone flour 8, calcium monohydrogen phosphate 0.7, salt 0.3 and premix 1.
Because the cost of the relative corn of cost, dregs of beans and the inferior powder of rice bran and palm kernel meal is lower, therefore under the situation that yolk color and laying rate are more or less the same, can increase part rice bran and palm kernel meal to reduce cost.
Take all factors into consideration from economic benefit (cost, yolk color and laying rate), the weight proportion of the preferred laying duck special feed of the present invention is: corn 30, dregs of beans 21, inferior powder 33, palm kernel meal 5, fresh rice bran 1, stone flour 8, calcium monohydrogen phosphate 0.7, salt 0.3 and premix 1.
After testing, every nutritive index of the laying duck special feed made of the present invention is: crude protein 〉=18%, lysine 〉=1.0%, methionine+cystine 〉=0.7%, calcium 3.0%, phosphorus 0.4%, moisture≤12%, riboflavin 〉=30mg/kg.
The invention has the beneficial effects as follows: the present invention is by the meticulous collocation to various raw materials in the special feed, particularly additionally added a certain amount of riboflavin in the premix, both satisfy the egg duck and produced nutritional needs such as required energy, albumen, amino acid, vitamin, strengthened immunity of organisms, improved production performance, made Ovum Anas domestica yolk be glassy yellow again.Compare with using other feed, use the laying duck special feed that improves the Ovum Anas domestica yolk color and luster of the present invention, can make laying rate improve about 5%, the yolk color grade improves about 15%, and egg duck culture benefit improves 3-5%.
