Embodiment 1

[0025] According to the feed additives of the present invention to prepare the corresponding feed, the specific steps are as follows:

[0026] (1) Preparation of active liquid: Lactic acid bacteria solution and 98% aqueous sodium selenite according to the volume ratio of 2%.

[0027] Preparation of lactic acid bacteria solution: according to weight, 10.0 parts of peptone, 10.0 parts of beef extract, 5.0 parts of yeast extract, 20.0 parts of glucose, 5.0 parts of sodium acetate, 2.0 parts of diamine citrate, 80 parts of Tween 1.0 parts, dipotassium hydrogen phosphate 0.4 parts, magnesium sulfate 0.58 parts, manganese sulfate 0.29 parts, calcium carbonate 20.0 parts h and agar 15.0 parts as the base substrate for mixing evenly, control pH to 6.3 parts, stir and heat, boil for 2 minutes, at 121 °C, Sterilize at 0.1Mpa to ensure that the bacterial content in the substrate does not exceed the preset range, then inoculate the target lactic acid bacteria, culture, and dilute by normal sa...

Embodiment 2

[0035] The trial selected 240 25-week-old 25-week-old eggs with similar egg laying rates, randomly divided into 3 groups of 5 replicates and 16 replicates each. According to the feed prepared in Example 1, the control group fed the basic feed, the test group fed the feed with 1%, 1.5% feed additives added to the base diet, the pre-trial period is 1 week, and the positive trial period is 6 weeks. The test layer chickens are divided into two layers of ladder cages, each repeatedly distributed evenly in the chicken coop, free to eat and drink water, natural light and artificial light combined, natural ventilation and lateral negative pressure ventilation combined, cleaning chicken manure and egg picking twice a day, according to the conventional procedures for chicken immunization and pen disinfection.

[0036] During the trial period, the average feed intake of each group of layer chickens, their daily egg production and total egg weight were recorded every day. At the end of the ex...

Abstract

The invention discloses a feed and a feed additive for improving egg quality, the feed additive comprises selenium-rich dark tea, a microecological preparation, organic trace elements and raspberry seed polyphenol extract, the feed additive comprises the following components in parts by weight: 45-60 parts of selenium-rich dark tea, 18-25 parts of microecological preparation and 15-25 parts of raspberry seed polyphenol extract, and 1-5 parts of organic trace elements. By adding the feed additive into the feed, the body function of the laying hens is improved, so that the oxidation resistance and the immunity of the laying hens are improved, the disease resistance and the nutrient absorption and conversion capacity of the laying hens are improved, the egg laying performance of the laying hens is promoted, and the egg quality is improved.

Description

Technical field [0001] The present invention relates to the field of feed technology, in particular to a feed and feed additive for improving egg quality. Background [0002] At present, China's layer chicken industry scale, intensification continues to increase, eggs have become an important source of protein intake, in the traditional breeding industry, feed usually contains a large number of added antibiotic drugs, in order to reduce the incidence of livestock and poultry, improve production efficiency, but this move will also reduce the quality of livestock products, and cause harm to human health. With the complete ban on the use of antibiotics in feed in China, the resulting decline in livestock and poultry production performance and the rise in the rate of dead sales have become urgent problems to be solved. The existing invention application number CN110881566A discloses a black tea feed, preparation method and method of breeding layer chickens with black tea leaves soak...
