Embodiment 1

[0020] Egg duck additive premix for alleviating the hard heart of salted egg yolk, wherein the premix includes the following ingredients: containing soybean isoflavones 10mg / kg, vitamin E 40mg / kg, the carrier of the premix is ​​stone powder, zeolite powder or bentonite. The feed additive premix is ​​added to the complete feed for laying ducks at a ratio of 200-300 g / ton.

[0021] The feed additive premix is ​​suitable for laying ducks and laying ducks with both meat and eggs. The salted egg yolk hardness test was carried out on duck eggs produced by feeding laying ducks with the feed additive premix. A total of 360 19-week-old Longyanshan shelducks with average body weight were selected and randomly divided into 2 groups, with 6 replicates in each group and 30 ducks in each replicate. The test ducks were reared in double-layer stepped single cages in 40×40×60 cm galvanized wire duck cages. Feed the basal ration (control group) and basal ration+300g / ton of laying duck additi...

Embodiment 2

[0051] Egg duck additive premix for alleviating the hard heart of salted egg yolk, wherein the premix includes the following ingredients: soybean isoflavone 6mg / kg, vitamin E 60mg / kg, the carrier of the premix is ​​stone powder, zeolite powder or bentonite. The feed additive premix is ​​added to the complete feed for laying ducks at a ratio of 200-300 g / ton.

Embodiment 3

[0053] Egg duck additive premix for alleviating the hard heart of salted egg yolk, wherein the premix includes the following ingredients: containing soybean isoflavones 15mg / kg, vitamin E 20mg / kg, the carrier of the premix is ​​stone powder, zeolite powder or bentonite. The feed additive premix is ​​added to the complete feed for laying ducks at a ratio of 200-300 g / ton.

Abstract

The invention discloses a laying duck additive premix for relieving salted egg yolk core hardening and a use thereof and relates to the field of feed additive premix production. The laying duck additive premix comprises additives and a carrier. The additives comprise 6-15mg / kg of soy isoflavone and 20-100mg / kg of vitamin E. The carrier is cob powder, zeolite powder or bentonite. The laying duck additive premix is rich in biologically active substances and vitamins, has biological functions of improving a body antioxidation capability, has no toxic or side effect, is beneficial for laying duck laying and human health and is prepared and used through simple and convenient processes. The laying duck additive premix is used for laying duck and laying breeding duck feed, improves a body antioxidation capability, improves duck egg quality, reduces salted egg yolk fat and protein oxidation, promotes salted egg yolk oil production and arenaceous taste formation, reduces salted egg yolk core hardening and is environmentally friendly and safe.

Description

technical field [0001] The invention relates to the field of feed additive premix production, in particular to an egg duck additive premix for alleviating the hard core of salted egg yolk and an application thereof. Background technique [0002] In recent years, with the advancement of my country's waterfowl industrialization process, conventional energy and protein feed resources are in short supply. Unconventional feed is widely used in laying duck feed to alleviate the shortage of feed resources such as corn and soybean meal, reduce feeding costs, and improve economic benefits. , the quality of salted egg yolk has declined year by year. It is mainly manifested in the hard heart of salted egg yolk, the increase of white heart rate, and the decrease of the proportion of oil and sand, which has caused huge economic losses to the food industry such as moon cakes, zongzi, and egg yolk pies related to salted egg yolk. The nutrition of unconventional feed is unbalanced. The by-p...
