Faced with the long-term downturn in egg prices, feed mills are struggling with product management. The market for layer chickens is very large, and manufacturers are reluctant to operate egg yolks because of high raw material costs and low egg prices. Farmers are still bitter. The weather has low food intake, the eggs become smaller, and the peak egg production time is short. After the peak season, the egg production drops rapidly. The reason is that the amount of nutrients needed by a chicken in a certain period of time is certain. Because the amount of caloric intake is reduced, the feed nutrients that are eaten cannot get its growth and production needs, thus leading to the aforementioned series of problems. In fact, the ability of livestock and poultry to digest feed nutrients is mainly determined by the type and activity of digestive enzymes in the digestive tract. In response to this feature, manufacturers at home and abroad have produced a variety of compound enzyme preparations to improve the digestibility of nutrients in feed and to achieve low input and high output. After comparison of various experiments, the compound enzyme preparation produced by SinSui Corporation of Japan, which has the most significant effect, has been used for reference in order to enable it to be used rationally during the laying period of laying hens.
Goji Berry is taken as one of the most famous plants, which can be both for medical and eating use. The history of goji berry up-picking and for eating use has a long history of 4000years in China. People from different social hierarchies, from the emperor to ordinary people, take goji berry as a good component of medical prescriptions. Goji berry enjoys a great popularity from ancient to modern times, at home and abroad and it has a long lasting and profound life preservation culture.
Ningxia Goji Berry enjoys a great fame around the global due to its high quality standard; meanwhile, it is the only protected product of geographical identity in China, goji berry has a great popularity describes as "goji berry of the world is in China, goji berry of China is in Ningxia and Ningxia`s goji berry is the best".

First, materials and methods:
1. Test compound enzyme:
SLEFEED The enzyme activity developed and produced by SINSUI of Japan is labeled as: Protease 5,000,000 IU/kg
Amylase 37,500,000 IU/kg
Cellulase 2,000,000IU/kg
Lipase 1,500,000 IU/kg
Colloidal enzyme 1,000,000 IU/kg
Active rare earth (appropriate amount)
2. Test objects and grouping:
1800 laying hens (later peak of egg production) were selected and divided into experimental groups according to the same species (Rohman white) and the same age (332 days old), and the same family (three rows in total, each group is divided into 600 groups). , Control group 1, control group 2, pre-test 3 days into the formal test.
3. Test diet composition and nutritional level: (see Table 1)
Feed composition test group plus fungus enzyme (200g/T) Control group (1) Control group (2) Nutrition level test group Control group (1) Control group (2) Corn 62.71 62.71 60.6 Metabolic energy 2600 2600 2735 Soybean meal 16.5 16.5 3 Crude protein 16 16 16.8 Cottonseed 5 5 3 Calcium 3.45 3.45 3.45 Vegetable pod 3 3 3 Available phosphorus 0.37 0.37 0.38 Fishmeal 2 .5 Lysine 0.71 0.71 0.75 Mycelial protein 2 2 2 Methionine 0.35 0.35 0.38 Stone powder 8.1 8.1 8 Calcium hydrogen phosphate 1.39 1.39 1.30 Salt 0.3. 0.3. 0.3. Premix 1 1 1 The test group and the control group 1 have the same ratio and nutritional level, and the control group 2 has a 5% higher nutrition standard than the test group (calculated at a price of 0.06 yuan per kilogram of feed).
4. Test time and test cycle:
From July 2 to July 30, 2000, the 28-day statistical intake of food intake, egg weight, egg production rate, and material-to-egg ratio. test results:
1. Daily feed intake, egg production rate, egg weight, and egg to egg ratio during the trial: see (Table 2)
Table 2 Average daily feed intake of the project group (g) Average egg production rate (%) Average egg weight (g) Egg to egg ratio during the test period 92 80.2 Experimental group 56 2.04:1 Control group 1 98 73.6 54 2.46:1 Control group 2 94 80 56.5 2.08:1 2. Feed intake:
The total food intake of the experimental group, the control group 1 and the control group 2 during the whole period was: 2596 g per chicken; 2744 g; 2632 g; the test group decreased by 5.7% compared to the control group 1 and decreased by 1.39% compared to the control group 2.
3. Egg production rate:
The average egg production rates of the experimental group and the control group 1 and the control group 2 were 80.2%, 73.6% and 80%, respectively, and the average egg production rate of the test group was 8.97% higher than that of the control group 1. The test group was more than the control group 2 The average egg production rate is 0.25% higher.
4. Egg weight:
The average egg weights of the test group and the control group 1 and the control group 2 were 56 g, 54 g, and 56.5 g, respectively. The experimental group had an average egg weight of 3.7%, and was 0.89% lighter than the control group 2.
5. The material-to-egg ratio of the test group to the control group 1 and the control group 2 during the ratio test was 2.04:1; 2.46:1; 2.08:1. If the feed per kg was calculated at 0.63 yuan (current price), the test The cost of changing a pound of eggs between the group and the control group was 1.3117 yuan (enzyme plus) and 1.5496 yuan, and the cost of the control group 2 was 1.3728 yuan (feed cost 0.66 yuan/kg). summary:
In this experiment, the compound enzyme-feeding enzyme was used, and the effect was very significant. Compared with the feed with the same level of nutrition, the feed intake was reduced by 5% after the feed enzyme was added; the egg production rate was increased by 897%; the egg weight increased by 3.7% The cost of the final exchange of 1 pound of eggs was reduced by 18.0%, and the cost per kilogram of eggs that was 5% higher than the nutritional level was also 4.71% lower. From the comparison between the test group and the control, the energy levels differ by more than 100 kcal/Kg. Similar production results can still be obtained, showing that the addition of feed enzymes can increase the energy level of the feed.
According to reports, adding 200 grams of feed enzyme per ton of feed can increase the digestion and absorption rate of protein and other nutrients in the feed by more than 10%, and can increase the metabolic level of the feed by more than 100 kcal/Kg, which is a high-yielding chicken group in summer. It is undoubtedly a good additive to produce poorly nutritious chickens. When the feed contains many raw materials with low digestibility, such as cotton amaranth, the addition of feed enzyme should also be more effective.
