Table 3 experimental grouping protocol for examples 1-10:

(1) test examples (growth performance feeding experiments of 30-60kg growing pigs) the experimental results:

the test was performed in 5 treatment groups, each treatment group was performed in 4 replicates, each replicate for 6 pigs, and each half of the boar and the female. Treatment 1 was a control group (0.75 kg of microencapsulated (coated) aureomycin and 0.4 kg of bacitracin zinc premix per ton of feed) fed 30-60kg of type a growing pigs diet of example 1. Treatment 2 was a test group with 5 wt.% of the a high-end growing pig compound feed composition of example 2 (oven-dried high-end biological feed product) added on the basis of the control group ration without antibiotics. Treatment 3 was a test group to which 5 wt% of the a high-end exo-growing pig formula feed composition of example 3 (a high-end fermented biological feed product having a water content of 38.82 wt%) was added on a control group diet type a. Treatment 4 was a test group to which 5% of the growing-pig type a compound feed composition of example 4 (oven-dried high quality biological feed product) was added on a daily basis to a control group containing no antibiotics. Treatment 5 was a test group to which 5 wt% of the high quality exo-growing pig compound feed composition of example 5 a (high quality fermented biological feed product having a water content of 38.67 wt%) was added on a control group ration basis.

0.75 kg of micro-capsule (coating) aureomycin, 0.4 kg of bacitracin zinc premix and 0.3 kg of complex enzyme preparation are added into each ton of the control group growing pig A daily ration, and the two antibiotics are not added into other growing pig daily ration A high-end and high-quality biological feeds (see table 2).

The test adopts the mode of flat culture in an isolation fence, natural illumination and free food intake and water drinking. Temperature, ventilation and immunization were performed as prescribed in the field.

Test detection index

Pigs were weighed at the beginning and end of the trial. The feed intake of each pigsty, the number of pigs with diarrhea, the number of pigs dead, and the age and weight of the pigs dead were recorded daily. The weight of the remaining material in each column was recorded at the end of the test. And calculating average daily gain, average daily feed intake, material-weight ratio and profit. The calculation formula is as follows:

average daily gain is (final weight-initial weight + weight of culled pigs)/total number of test days;

average daily food intake is the sum of material consumption/test days;

the feed weight ratio is the average daily feed intake/average daily gain.

The results obtained are shown in Table 4:

TABLE 4 Effect of different biological feeds on the growth behavior of growing pigs

The test data are analyzed by adopting a GLM model of SAS 8.2 statistical software, the results are represented by mean values and average standard errors of all treatments, and the difference is obvious when P is less than 0.05.

The test results are shown in Table 4. Initial body weights of treatment groups were not significantly different at the start of the experiment (p > 0.05). At the end of the trial, the average individual weight of the pigs was maximized in the 5 treatment groups, and the results were higher in each trial group than in the control group, but showed insignificant differences between the treatment groups (p > 0.05). The result of the pig average daily gain treatment 4 added with 5 wt% of the dried high-quality biological feed product group is worse than that of other treatment groups, and the difference between the treatment groups is not obvious (p is more than 0.05). The differences between the mean food intake of the treatment groups appeared insignificant (p >0.05), but the mean food intake of the test groups was higher than that of the control group from the data point of view. The feed-meat ratio also appeared to be not significantly different (p >0.05) in statistical analysis between treatment groups.

From the test results, each test group showed superior results in terms of end body weight and average feed intake data to the control group, but showed insignificant differences between the treatment groups (p > 0.05). The difference between the feed-meat ratio and the average daily gain data was also shown to be insignificant (p > 0.05). The weight and feed intake of the biological feed pigs added in the test have a certain positive effect, but the product ability of the biological feed pigs is to be further improved.

The biological feed contains small peptides, and the live bacteria and lactic acid reduce the pH value, improve the palatability and improve the feed intake, thereby improving the production performance of the growing pigs due to the action of the live bacteria and the small peptides. Because no aureomycin, an antimicrobial peptide zinc premix and a complex enzyme preparation are added into high-end and high-quality biological feeds, the functional effects of small peptides, lactic acid, live bacteria and the like in fermentation products in the biological feeds can replace or reduce the usage amount of antibiotics and enzyme preparations.

(2) Test example (60-90kg fattening pig growth performance feeding experiment) the experimental results are as follows:

the test was performed in 5 treatment groups, each treatment group was performed in 4 replicates, each replicate for 6 pigs, and each half of the boar and the female. Treatment 1 was a control group (0.75 kg of microencapsulated (coated) aureomycin and 0.4 kg of bacitracin zinc premix per ton of feed) fed to a conventional 60-90kg growing pig ration (type B of example 6) without added biological feed from the diet feed (Chengdu) limited. Treatment 2 was a test group to which 8 wt% of the B high-end type fattening pig compound feed composition of example 7 (oven-dried high-end biological feed product) was added on the basis of the daily ration of the antibiotic-free control group. Treatment 3 is a test group in which 8 wt% of the B high-end finishing pig formula feed composition of example 8 (a high-end fermented biological feed product having a water content of 38.82 wt%) was added on the basis of the control group ration. Treatment 4 was a test group to which 8% of the high-quality type B fattening pig compound feed composition of example 9 (oven-dried high-quality biological feed product) was added on the basis of the daily ration of the antibiotic-free control group. Treatment 5 was a test group to which 8 wt% of the high-quality exterior finishing pig compound feed composition of example 10 (high-quality fermented biological feed product having a water content of 38.67 wt%) was added on a control group ration basis.

0.75 kg of microcapsule (coating) aureomycin and 0.4 kg of bacitracin zinc premix are added into each ton of the control group growing pig B type daily ration, and the two antibiotics are not added into other growing pig B high-end and high-quality biological feeds (see table 2).

Test detection index

average daily food intake is the sum of material consumption/test days;

the feed weight ratio is the average daily feed intake/average daily gain.

The results obtained are shown in Table 5:

TABLE 5 influence of the addition of different biological feeds on the growth performance of fattening pigs

Note: all means are ranked in order from large to small using the SPASS significant difference alphabetical difference method. The maximum average is labeled with the letter a, and each average, if not significantly different, is labeled with the letter a. The difference in the mean is marked with the letter b. Between the averages, the differences are not significant if there is a same marked letter, and the differences are significant if there are different marked letters.

The test results are shown in Table 5. Initial body weights of treatment groups were not significantly different at the start of the experiment (p > 0.05). At the end of the trial the average individual weight of the pigs was greatest for treatment 5 groups, but showed no significant difference between treatment groups (p > 0.05). The average daily gain of pigs treated with 2% of the oven-dried high-end biological feed product was worse than that of the other treated groups, and the difference between the treated groups was not significant (p > 0.05). The value of the average daily food intake was the highest in the treatment group 5, and the difference between the treatment group 5 and the treatment groups 2 and 4 was significant (p <0.05), while the average daily food intake of the control group was not significant (p >0.05) from the test groups. The feed-meat ratio also appeared to be not significantly different (p >0.05) from treatment group to treatment group in statistical analysis, but the feed-meat ratio of treatment group 5 appeared to be optimal. The comparison between the groups fed with the high-quality fermented biological feed shows that the indexes of the 5 groups treated by adding the high-quality fermented biological feed with 8 percent of water content and 38.67 percent of water content are all better than those of the 4 groups treated by adding the 8 percent of dried high-quality biological feed, and the same result is shown between the high-end fermented biological feed groups, which indicates that the production performance of the pigs is better than that of the biological feed group fed with the dry base by adding the wet-base biological feed with the water content of 38.67 percent or 38.82 percent.

According to test results, the test group added with the high-quality fermented biological feed with 8 percent of water content and 38.67 percent of water content is superior to other treatment groups in the weight of the test pigs at the end, the average daily gain, the average feed intake and the feed-meat ratio. The indexes of the treatment group externally added with the high-quality or high-end fermented biological feed with the water content of 38.67 percent or 38.82 percent are superior to those of the treatment group added with the high-quality or high-end biological feed with 8 percent of drying, which indicates that the production performance of the pigs externally added with the wet-based biological feed with the water content of 38.67 percent or 38.82 percent is superior to that of the biological feed group fed with dry base.

The biological feed contains small peptides, and the living bacteria and lactic acid reduce the pH value, improve the palatability and the feed intake, thereby improving the production performance of the fattening pigs due to the effects of the living bacteria and the small peptides. Because no aureomycin and nisin zinc premix is added in the high-end and high-quality biological feeds, the functional effects of small peptides, lactic acid, viable bacteria and the like in the fermentation products in the biological feeds can replace or reduce the use amount of antibiotics.

As can be seen from tables 4 and 5, the feed conversion ratio can be significantly lower by using the compound feed composition for growing-finishing pigs, the feed conversion ratio can reach a better level in the field by using the compound feed composition for growing-finishing pigs which is more preferable in the invention, and the feed conversion ratio can be significantly reduced by using the wet biological feed by comparing examples 1 and 6 with examples 5 and 10.

(3) And (3) calculating the cost:

taking 60-day-old growing pigs and 90-day-old fattening pigs as examples, the cost calculation formula of each pig is as follows: cost (yuan/pig) is the price of feed, feed-meat ratio and weight gain (kg/pig). The results obtained are shown in Table 6.

TABLE 6

As can be seen from Table 6, the cost of the compound feed composition for the growing and fattening pigs can be effectively saved, even 0.68 yuan can be saved for each growing and fattening pig on average, and 13600 yuan can be saved by taking the number of the growing and fattening pigs in a growing and fattening pig farm as 20000. On the basis of ensuring the breeding effect and not increasing the formula cost of the pig feed, the invention can completely replace the aureomycin microcapsules (coating) and the bacitracin zinc premix (10%) used in the compound feed composition for pigs, thereby achieving the effect of partially replacing antibiotics.
