3.5 Test data and sorting: Daily record of the number of deaths, feed consumption, temperature, humidity, medication and epidemic prevention in each group. When the chicks enter the fair, all the chicks are weighed; 3% of the chicks are weighed every week, and the weekly report is compiled; the weight of the broiler is converted according to carcass weight at the time of slaughter, and finally the performance indicators and economic benefits are analyzed.
4. Test results (schedule 1, 2, 3) 4.1 Weight gain: As can be seen from Table 1, 0-21 days of age: daily weight gain, average weight, the test group was slightly worse than the control group, but the difference was not significant; 22-35 days of age: daily gain, the test group was better than the control group, the average body weight test group was slightly better than the control group; 36 days old - slaughter, the test group daily gain was significantly better than the control group, the average body weight was better than In the control group, there was a large gap between the two groups. During the whole process, the daily weight gains. The experimental group also showed that the experimental group was significantly better than the control group. Table 1 Daily gain weight, average body weight, and feed conversion index of the test chickens Daily average weight gain (g) Average body weight (g) Feed conversion ratio (?:1) 0-21 days old 22-35 days old 36-52 days old Full-term 21 days of age, 35 days of age, 52 days of age, 0-21 days of age, 22-35 days of age, 36-52 days, full-term B test group, 27.36666.568.851.4614154527141.4301.7451.8991.740F control group 27.6465.062.948.9621153025161.4251.7292.0481. 784 Note: The control group slaughtered at 51 days and the test group slaughtered at 52 days. 4.2 Feed conversion rate: As can be seen from Table 1, from 0 to 21 days of age, the flesh ratio is slightly higher than that of the control group, but the difference is not significant; the feed-to-meat ratio of the 22-35 day-old experimental group is slightly lower than that of the control group. In the control group, the difference was not significant; in the 36-52 slaughter, the feed-to-meat ratio of the experimental group was significantly lower than that of the control group. During the whole process, the meat of the experimental group was 0.044 lower than the control group, and the feed conversion rate was improved by 2.5%. 4.3 Death and survival rate of chickens: (Table 2) Table 2 Bird mortality and survival rate Statistical stage Treatment 0-21 days old 22-35 days old 36-52 days old (0-52 days old) Number of deaths (only) Survival rate (%) Number of deaths (only) Survival rate (%) Number of deaths (only) Survival rate (%) Number of deaths (only) Survival rate (%) Test group B16497.528398.7123096.3847792.77 Control group F21496 .8010298.4319097.0250992.40 As can be seen from Table 2, the 0-21 day old experimental group and the control group are all eliminated, and there is no significant difference in the survival rate; between 22 and 35 days, the difference in the number of deaths between the groups is not large, and the survival rate is not significant. There was also a large gap between the experimental group and the control group; at 36 days of age-slaughter, there was not much difference in the survival rate between the experimental group and the control group. During the whole process, there was no significant difference in mortality between the experimental group and the control group. High, but basically belong to the normal elimination range, the survival rate test group and the control group is equivalent. 4.4 Evaluation of economic benefits: (Annex 3) As can be seen from Table 3, the experimental group has better economic benefits, and the chicken gross profit is 0.76 yuan higher than that of the control group. This benefit is calculated at the same feed price. Table 3 Economic Benefit Assessment Indicators Target Treatment Carcass Gross Weight (Kg) Chicken Sales Revenue (yuan) Feed Consumption (tons) Feed Cost (yuan) Chicken Stock (yuan) Drug Cost (yuan) Gross Profit (yuan) Chicken Gross Profit (yuan ) profit difference (yuan) B test group 11621.6115976.828.9662167.414671.88572.230565.44.990.76F control group 10993.4109752.127.9260003.8514905.88667.426175.054.230 5. Analysis of test results: 5.1 From the point of view of weight gain, from the comparison of growth status of normal chickens, although the experimental group was slightly worse in the early period, the weight gain in the middle and later stages was significantly better than the control group, demonstrating that the use of enzymes was promoted. The growth of broilers has a better effect, especially for the performance of weight gain in the middle and later stages. 5.2 From the perspective of feed conversion ratio, the final feed ratio of the experimental group was significantly lower than that of the control group, and the nutritional level of the experimental diet was slightly lower than that of the control group, demonstrating that the improvement effect of the enzyme preparation on the feed conversion ratio was also significant; 5.3 In terms of the health status and survival rate of chickens, the health status of chickens in both the experimental group and the control group was basically normal, and there was no significant difference in mortality, titer, feces and so on. Feeding enzymes are comparable to Everwin-1502 in improving the health of broilers. 5.4 In view of the overall effect, the performance of the chickens and the raising of the breeding efficiency have obvious advantages in the experimental group. Although the dietary nutrient level of the experimental group has been reduced (the cost of the ton feed has dropped by more than 20 yuan), the The results were unaffected, and it is undeniable that the effect of the enzyme applied on the feed was present. 6. Discussion and summary: Feeding enzyme adopts special solid culture technology and advanced zymogen production and processing technology. Through specific formulation technology, it will be high unit protease, amylase, cellulolytic enzyme, lipase, pectin decomposing enzyme, etc. High-purity active enzyme complex enzyme preparation. Non-starch polysaccharides (NPS), glial proteins and other anti-nutritional components contained in plant feedstuffs for animal feeds affect the digestion and absorption of other nutrients by animals. Different enzymes in enzyme preparations can improve the anti-nutritional components. Negative effects, promote the digestion and absorption of nutrients, feed enzyme has a wide range of effects, a strong ability to decompose, good thermal stability and high temperature stability. This feeding experiment was not accidental because of the production performance of broilers and the performance test of broilers. It was also a further verification of the effects of the enzyme preparation. It was combined with previous tests on lovage enzymes, either alone or in combination with The use of other products in combination, whether it is the comparison of the same level of nutrition, or the verification of lowering the level of nutrition, the effects of the feed enzyme are reflected to varying degrees. Based on the results of multiple experiments, the use of feed enzyme is appropriate to reduce the level of feed nutrition. It is feasible to reduce the cost of feed, and it is recommended to promote it.
Flavor: Ningxia goji berry is astringent at first bite then sweet, without ill-smell.
