Example 6 Effect of Chinese medicinal granule on growth Performance of fattening pig
1. Materials and methods
1.1, experimental design and feed:
a single-factor completely random experimental design is adopted, 216 dux long x big binary hybrid fattening pigs with the average weight of (30.0 +/-2.0) kg are selected and randomly divided into 6 groups, namely I, II, III, IV, V and VI groups. Each group had 6 replicates, each replicate 6 pigs. Group I is control group, fed with basal feed, group II-VI is test group, and 1, 2, 3,4, 5g/kg of Chinese medicinal granule (corresponding to examples 1-5) are added into the basal feed. The corn-soybean meal type basic diet is adopted, the feeding level is prepared by stages according to the feeding standard of pigs (NY/T65-2004) and the feeding standard of NRC (1998) growing-finishing pigs, and the composition and the nutrition level are shown in Table 1.
TABLE 1 basic diet composition and nutritional levels (air-dried basis)
Figure BDA0001508484840000091
The Premix is prepared from 8000IU of VA, 2000IU of VD, 30IU of VE, 31.5mg of VK, 11.6 mg of VBE, 61.5 mg of VBE, 1212 ug of VB, 15mg of D-pantothenic acid, 20mg of nicotinic acid, 80mg of Zn, 100mg of Fe, 20mg of Cu, 25mg of Mn, 0.3mg of I and 0.2mg of Se per kilogram of feed.
1.2, feeding management and sample collection:
the feeding test is carried out in a certain pig farm of the city of the various varieties in Sichuan province from 2016 (9 months) to 2016 (12 months), and the feeding period is 60 days. Free intake and drinking water, and conventional management. After the feeding test is finished, 1 test pig is randomly selected for each repetition to be slaughtered. The longissimus dorsi of the left carcass half within 2h after slaughter was taken for meat quality assessment.
1.3 detection index of growth Performance
At the beginning and end of the feeding trial, the test pigs were fasted (free drinking) for 12h and then weighed on an empty stomach in the morning of the day, and the initial and final weights of the test pigs were recorded and the feed consumption was counted in duplicate. The Average Daily Gain (ADG), Average Daily Feed Intake (ADFI) and feed to weight ratio (F/G) were calculated for each group.
1.4 data processing
The experimental data were analyzed for one-way anova using SPSS 18.0 statistical software and multiple comparisons of mean values between groups were made using the Duncan method. The test results are expressed as "mean ± sem", and P <0.05 is used as the criterion for judging the significance of the difference.
2. The influence of Chinese medicinal granule on growth performance of fattening pig
The influence result of the traditional Chinese medicine granules on the growth performance of the fattening pigs is shown in table 2; as can be seen from table 2, the end weight and average daily gain of each experimental group added with the Chinese medicinal granules tend to increase compared with the control group. Wherein the average daily gain of the IV group, the V group and the VI group is obviously higher than that of the control group (P <0.05), and the average daily gain of the II group and the III group is not significantly different from that of the control group (P > 0.05); the material weight ratio of the groups except the group II and the group III is obviously lower than that of the control group (P < 0.05).
