Layer chicken feed：Layer chicken feed in the present invention.
1.2 experimental design
Blue brown laying hen 5340 of 52 week old sea, is randomly divided into 3 groups, every group of 5 weights similar in this test selection health, weight It is multiple, every repetition 356.
Preliminary trial period is 10 days, and each group feeds basal diet.Experimental period is 60 days, and blank control group continues to feed basic day Grain, the above-mentioned layer chicken feed of test group.The phosphoric acid Thailand of blank control group addition 80% in daily ration from positive the 7th day examination phase is happy 62.5g/ tons of rhzomorph pre-mixing agent, i.e. Tylosin phosphate 50mg, continuous feeding 5 days are added in every kilogram of daily ration.
1.3 feeding management
For laying hen using three layers of iron cage raising, it is suitable for well-ventilated that the temperature humidity in henhouse is kept during test, and daily 16 Hour illumination, 3 hand feds manually pick egg 2 times, and chicken free water is immune by vaccination programs for poultry health.
1.4 testing indexs and method
1.4.1 performance in layers index determining
Experimental period, records inventory and surplus doses daily, and when off-test calculates average daily gain；Egg is collected daily, Record, which is laid eggs, piece number and weighs, and records broken egg number, calculates average egg weight and feedstuff-egg ratio.
1.4.2 egg quality index determining
On-test and at the end of, 3 pieces of eggs of each repeated collection, measurement shell thickness, eggshell strength, Hough unit and Yolk color.
1.5 data processing
Test data carries out one-way analysis of variance using SPSS19.0, carries out Multiple range test, difference with Duncan ' s method Significance is set as P<0.05, test data is indicated with " mean+SD ".
2 results and analysis
Influence of 2.1 egg feedstuffs to performance in layers is shown in Table 1
Table 1
Note：With the female different expression significant difference (P of column data shoulder marking-up<0.05), same letter indicates the not significant (P of difference > 0.05), following table is same.
As shown in Table 4, test group average daily gain is 2.7g fewer than control group, and the amplitude that reduces is 2.3%；Test group material egg Than all reducing by 0.05 than control group, the amplitude that reduces is 2.2%；The average egg weight of test group improves 0.09g.Compare between two groups Difference, not significant (p>0.05).
Influence of 2.2 layer chicken feeds to egg quality see the table below
Table 2
As shown in Table 2, three groups of egg shape indexes are close；The shell thickness of test group is 1.36 × 10-2mm higher than control group, mentions High-amplitude is 3.9%；The eggshell strength of test group is 2.46N higher than control group, has been respectively increased 9.1%；Test group Hough unit Lower than control group 2.0, reduce 2.5%；Test group yolk color is higher than control group by 1.1, has been respectively increased 16.7%, test group Yolk color is deeper.Egg shape index, eggshell strength, shell thickness, albumen height, Hough unit and yolk color between two groups Difference it is not significant (p > 0.05).
3 conclusions
Using the layer chicken feed that the present invention develops, remove prevention antibiotic, to the egg laying performance and Egg Quality of laying hen And it does not make significant difference.Wherein feedstuff-egg ratio has decreasing trend, and average egg weight is improved trend, and eggshell strength also increased.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with Understanding these embodiments can be changed without departing from the principles and spirit of the present invention, the scope of the present invention by The following claims and their equivalents limit.

The preparation step of S1, saccharomyces cerevisiae seed：By saccharomyces cerevisiae in mass ratio 1：10 inoculum concentration accesses seed culture medium, Temperature is 25-35 DEG C, revolving speed is 16~18hr of culture under 150-200rpm, and the saccharomyces cerevisiae kind of fermentation palm kernel meal can be made Son, wherein the seed culture medium includes the glucose that mass ratio is 1.8-2.2%, the yeast extract and 1-3% of 0.8-1.2% Peptone；
S2, fermentation step：By the saccharomyces cerevisiae seed access fermentor in bottom sugar culture-medium, temperature be 25-35 DEG C, turn Speed is 200~600rpm, ventilatory capacity 130-150m3Fermented and cultured r for 24 hours under/hr, wherein the bottom sugar culture-medium includes quality Than for：The sugar of 3-5%, the urea of 0.05-0.06%, the magnesium sulfate of 0.05-0.15%, 0.005-0.015% calcium chloride and The potassium dihydrogen phosphate of 0.05-0.15%, the pH value of the bottom sugar culture-medium are 6-7；Start stream after the 4hr that ferments to add, flows the added-time Between be 5hr, flow acceleration 1200ml/hr, stream plus the fed-batch medium that uses include that mass ratio is：Sugar, the 1- of 23-25% 1.5% urea, the magnesium sulfate of 0.05-0.15%, the calcium chloride of 0.005-0.015% and 0.05-0.15% biphosphate Potassium, the pH value of the fed-batch medium are 6-7；When the dissolved oxygen amount of culture medium in the fermentor drop to by volume 15% with When lower, the mixing component and dissolved oxygen electrode collaborative work for providing the revolving speed are greater than the dissolved oxygen amount of the culture medium by volume 15~20%, ventilatory capacity variation is 15~30L/min；
S3, solid fermentation step：Fermentation liquid in the fermentor is inoculated by the 10-20% of solid medium quality described On solid medium, ferment 24-72hr under anaerobic, then carries out drying and processing, and the leaving air temp of drying and processing is 70 DEG C, charging rate 2.5r/min.
