TABLE 5 Performance test results for different feeds
The detection results in the table 5 show that when the feed containing the feed additive obtained by the method is fed, the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are respectively 0.83kg, 1.52kg and 67.4% at most, so that the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are improved; the feed-meat ratio and the back fat thickness are respectively 1.83 cm and 2.47cm, and the growth performance of the fattening pigs is improved.
In application examples 1-3, when the feed obtained in application example 2 is fed, the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are respectively 0.67kg, 1.43kg and 61.4 percent, which are higher than those of application example 1 and application example 2, so that the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are improved; the feed-meat ratio and the backfat thickness of the fattening pig fed in the application example 2 are respectively 2.13 cm and 2.66cm, which are lower than those of the application example 1 and the application example 3; the result shows that the mixing amount of the eucommia ulmoides leaf extract in the raw materials of the feed additive for the fattening pigs in the example 2 is proper, and the growth performance of the fattening pigs is improved. May be related to the fact that the eucommia ulmoides leaf extract contains protein, fat, vitamins, minerals, trace elements and other nutrient components which can obviously increase the function of collagen in the animal body.
In application examples 4-7, when the feed obtained in application example 5 is fed, the average daily gain, daily average feed intake and lean meat percentage of the fattening pigs are respectively 0.70kg, 1.45kg and 62.3 percent, which are higher than those of application example 4 and application examples 6-7, so that the average daily gain, daily average feed intake and lean meat percentage of the fattening pigs are improved; the feed conversion ratio and the back fat thickness of the fattening pigs fed in the application example 5 are respectively 2.07 and 2.62cm, and are lower than those of the application example 4 and the application examples 6-7; the weight ratio of the astragalus polysaccharide to the composite probiotics in the raw materials of the feed additive for fattening pigs in the embodiment 5 is 1: and when 9 hours, the growth performance of the fattening pigs is improved. May be related to the regulation of the weight portion proportion of the astragalus polysaccharide and the composite probiotics, the side effect on the fattening pigs after the composite probiotics are added can be further reduced, and the growth performance of the fattening pigs is improved.
In application examples 8-10, when the feed obtained in application example 9 is fed, the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are respectively 0.72kg, 1.46kg and 63.6%, which are higher than those of application example 8 and application example 10, so that the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are improved; the feed-meat ratio and the backfat thickness of the fattening pig fed in application example 9 are respectively 2.03 and 2.59cm, and are lower than those of application example 8 and application example 10; the result shows that the red date polysaccharide in the raw materials of the feed additive for the fattening pigs in the example 9 is relatively appropriate in mixing amount, so that the growth performance of the fattening pigs is improved. The red jujube polysaccharide has the effects of immunoregulation, antibiosis, flora regulation and the like, particularly can promote the proliferation of beneficial bacteria and improve the intestinal function, and can induce organisms to generate specific vitamins and high-quality amino acid and improve the growth performance of fattening pigs.
The results of the feed detection data of application example 9 and application example 11 show that when the feed obtained in application example 11 is fed, the average daily gain, daily average feed intake and lean meat percentage of the fattening pigs are respectively 0.75kg, 1.47kg and 63.6 percent, which are higher than those of application example 9, so that the average daily gain, daily average feed intake and lean meat percentage of the fattening pigs are improved; the feed-meat ratio and the backfat thickness of the fattening pig fed in the application example 11 are respectively 1.96 cm and 2.57cm, which are lower than those of the application example 11; the results show that the growth performance of the fattening pigs is improved when the composite probiotics in the feed additive raw materials for the fattening pigs comprise 30kg of lactobacillus plantarum powder, 30kg of bifidobacterium longum powder and 40kg of pediococcus pentosaceus powder. The bifidobacterium longum powder can adjust the balance of beneficial bacteria of gastrointestinal microbial strains with lactobacillus plantarum powder, improve the immunologic function of the fattening pigs and possibly reduce certain disease risks through specific immune stimulation and intestinal environment acidification, improve diarrhea and constipation of the fattening pigs, reduce anxiety and depression so as to improve the feed conversion rate, improve the feed intake of animal organisms and promote the growth and development of animals.
In application examples 12-15, when the feed obtained in application example 15 is fed, the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are respectively 0.81kg, 1.50kg and 66.9 percent, which are higher than those of application examples 12-14, so that the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are improved; the feed-meat ratio and the backfat thickness of the fattening pig fed in the application example 15 are respectively 1.85 cm and 2.51cm, which are lower than those of the application examples 12-14; the result shows that the feed additive for the fattening pigs in the example 15 has proper mixing amount of the cassava dregs in the raw materials, and improves the growth performance of the fattening pigs. The feed conversion rate can be improved and the cost can be reduced with the cassava residue; the feed macromolecular substances can be decomposed into monosaccharide, amino acid and other micromolecular substances which are easy to digest and absorb, and a large amount of microbial thalli with rich nutrition and useful metabolites such as acid, vitamins, trace elements and the like are generated and accumulated, and in addition, the existence of the thalli and substances such as active enzyme secreted and synthesized by the thalli and the like greatly improves the nutritional value of the feed.
The results of the feed detection data of the application example 15 and the application example 16 show that when the feed obtained in the application example 16 is fed, the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are respectively 0.83kg, 1.52kg and 67.4 percent, which are higher than those of the application example 15, so that the average daily gain, the daily average feed intake and the lean meat percentage of the fattening pigs are improved; the feed-meat ratio and the back fat thickness of the fattening pig fed in the application example 16 are respectively 1.83 cm and 2.47cm, which are lower than those of the application example 15; the results show that the cassava residue is subjected to fermentation pretreatment in the feed additive raw materials for fattening pigs in example 16, so that the growth performance of the fattening pigs is improved. Is probably related to the fact that the cassava dregs after fermentation treatment have less mixed bacteria and toxic substances, can adjust and improve the functions of various organs of animal organisms and improve the feed conversion rate.
In addition, by combining the index data of comparative examples 1-3 and example 1, the growth performance of the fattening pigs can be improved to different degrees by adding the eucommia ulmoides leaf extract, the cordycepin and the astragalus polysaccharide into the feed additive raw materials.
