Description
Technical Field
The invention relates to the technical field of feeds (IPC (industrial personal computer) classification number is A23K 50/75), in particular to a low-bean pulp grain-saving feed for improving egg laying performance of laying hens and a preparation method thereof.
Background
The traditional feed formula structure in China mainly comprises corns and bean pulp, the bean pulp is a main feed protein source, the bean pulp for feed in China mainly comes from imported soybean squeezing production, and the yield of the soybean in China is less than 2000 ten thousand tons at present, but the demand is more than 1 hundred million tons, and 90% of the soybean needs to be imported. In recent years, the price of soybean meal in the international market rises faster and is unstable, a certain trouble is brought to the development of the laying hen breeding industry, and the multi-component formula, the low consumption of soybean meal and the reduction of risks become industry consensus. For this reason, the related departments are also actively advocating and advancing the reduction replacement of the fodder bean pulp. The unconventional feed raw material resources in China are rich, so that the application practice of the low-bean pulp laying hen feed is developed by combining the existing protein-rich raw material products in China, and the feed has important economic significance. The oil crops are rich in unsaturated fatty acid and plant active ingredients, have certain effects on improving immunity of laying hens, promoting intestinal health and improving production performance, and can produce remarkable effects on promoting health of chickens and improving egg laying performance through reasonable collocation and nutrition balance.
With the increasing demands of market consumers on the quality of eggs, high quality branded eggs are becoming the subject of egg consumption. As the special layer variety in China, the pink shell layer chicken is in line with the consumption habit of brand eggs, the stock quantity is increased year by year, and the 2022 quantity exceeds the feeding quantity of the traditional brown shell layer chicken. But the laying hens of the pink shell layer chicken strain have the problems of small majority of body types, low feed intake, poor stress resistance, high death and panning rate, short egg laying peak maintenance time, faster later-stage egg quality reduction and the like. Therefore, the feed needs to be designed with higher and more accurate nutrition level so as to meet the nutrition requirement of the feed for exerting the genetic potential of the feed, and more and better high-quality eggs with high and balanced nutrition content are obtained. In addition, the more accurate fodder nutrition design also can improve fodder conversion efficiency better, practices thrift grain, reduces the dirty emission of excrement and eases the environmental pressure that breeds and bring.
The invention patent with publication number of CN110012984A discloses a preparation method of pea-type laying hen egg-producing period ration, which can effectively improve egg white concentration and half units under a pea ration structure and produce high-quality and safe eggs; effectively promote intestinal mucosa function and avoid intestinal injury; the maximum nutrient digestion rate and the deposition rate of the pea-type ration are improved by adopting an enzyme preparation; the digestibility of pea starch is improved through an ultrafine grinding process, and the addition amount of bean pulp in daily ration is effectively reduced and the dependence on the bean pulp is reduced through scientific compounding of various raw materials and nutrients. Unlike the present invention, the present invention has mainly peas to replace bean pulp, and has low domestic peas yield and limitation. In addition, the invention adds 1-2 synthetic amino acids, only considers the balance of amino acid nutrition level, and does not consider the functional effect of amino acid.
The invention patent with publication number of CN110089625A discloses a laying hen feed containing waste culture medium of cordyceps militaris fruiting bodies and a preparation method thereof, and the composition comprises the following steps: 30-40 parts of cordyceps militaris fruiting body waste culture medium particles, 30-35 parts of corn, 10-15 parts of bean pulp, 1-2 parts of wheat bran, 8-10 parts of stone powder, 1-2 parts of calcium hydrophosphate, 5-8 parts of cotton pulp and 0.5-1 part of salt, wherein the cordyceps militaris fruiting body waste culture medium particles are prepared by mixing cordyceps militaris fruiting body waste culture medium with xanthan gum with concentration of 0.2-0.4% according to a weight ratio of 1:0.5-0.6. The invention also reduces the adding amount of bean pulp, but the waste culture medium particles of the cordyceps militaris fruiting bodies have limited sources on one hand, and special processing equipment and technology are needed on the other hand, so that the invention is not suitable for common laying hen farms.

Control group: the feed is prepared according to the conventional corn-soybean meal type laying hen feed in the market, and comprises the following components in parts by weight:
61.2 parts of corn, 25 parts of bean pulp, 8.7 parts of stone powder, 1 part of calcium hydrophosphate, 2.8 parts of bran, 0.3 part of soybean oil, 0.3 part of feed-grade sodium chloride, 0.2 part of multi-mineral egg chicken, 0.2 part of sodium bicarbonate, 0.1 part of sodium sulfate, 0.05 part of choline, 0.15 part of methionine, 0.03 part of compound egg chicken enzyme, 0.03 part of multi-vitamin egg chicken and 0.02 part of phytase.
The multi-mineral layer, the compound enzyme layer and the multi-dimensional layer are the same as in example 3.
Nutrient index of control group: 16.7% of crude protein, 2650kcal/kg of metabolic energy of laying hens, 3.6% of calcium, 0.52% of total phosphorus, 0.75% of digestible lysine, 0.65% of digestible methionine+digestible cystine, 0.53% of digestible threonine, 0.17% of digestible tryptophan, 0.60% of digestible isoleucine and 0.71% of digestible valine.
2. Measuring the index:
(1) Production performance index
During the test, the weight of eggs, the number of eggs laid and the number of stock chickens are recorded every day by taking the repetition as a unit, the average weight of eggs, the daily weight of eggs and the laying rate are calculated, the consumption of materials is recorded every week by taking the repetition as a unit, and the average daily feed intake is calculated.
(2) Egg quality index
Egg samples were collected every 4 weeks in duplicate units of 5 eggs each, and 4 egg quality indexes of eggshell strength, yolk color, egg freshness and pass rate were measured using a full-automatic egg quality tester (DET-6000, nabel corporation, japan).
(3) Feather scoring
At the end of the test period, 5 chickens were randomly selected for each repeat, and the feather status of the chickens was scored for neck, back, tail, wings, chest and abdomen with reference to the scoring method adopted by Tauson et al (Animal Science Papers and Reports, 2006) in Applied Scoring of Integument and Health in Laying Hens, with a score of 0 indicating no feather coverage at this location and a score of 4 indicating complete feather coverage.
The test results are as follows:
(1) Production performance results:
(2) Egg quality results:
| project | Control group | Experimental group |
| Freshness for 36 weeks | 89.1 | 90.3 |
| 48 weeks newFreshness degree | 86.7 | 87.8 |
| 36 weeks yolk colour | 7.2 | 7.1 |
| Color of 48-week yolk | 7.8 | 8.3 |
| 36 weeks eggshell strength kg | 3.75 | 3.81 |
| Eggshell strength kg 48 weeks | 3.62 | 3.73 |
| 36 weeks yield% | 99.2 | 99.1 |
| Yield per 48 weeks% | 97.6 | 97.8 |
(3) Feather scoring
| Project | Control group | Experimental group |
| Feather scoring | 3.2 | 3.7 |
Conclusion of experiment: after the laying hen uses the experimental formula, the egg laying performance and the egg quality are not obviously different, and the feather coverage is better than that of the conventional corn-soybean meal type daily ration. When the price of the bean pulp is high and the source of goods is in shortage, the soybean pulp can completely replace the conventional daily ration using the bean pulp.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
