Description

Technical Field

[0001] The invention relates to the technical field of feed preparation, in particular to a total mixed diet fermented with traditional Chinese medicine residues and application thereof in sika deer breeding. Background Art

[0002] Deer antler has high medicinal value and nourishing function. It is the king of traditional Chinese medicine. It has the functions of promoting growth and development, strengthening the body, immune regulation, anti-inflammatory, anti-aging, and promoting wound healing. Deer farmers and scientific researchers have conducted a lot of research on the nutritional metabolism, nutritional needs, and feed development of adult male deer through feeding, digestion and metabolism experiments since the early 1980s. They have achieved certain technical results in the feed and feeding management of male deer. Grass powder, fermented feed, and related additives have been applied in the efficient breeding of male deer. Light control deer breeding, FTMR daily diet feeding and other technologies have also been gradually applied, effectively reducing the cost of deer breeding and increasing the yield of deer antlers. The successful research on artificial insemination technology of deer has greatly accelerated the expansion and breeding of excellent deer species. Deer antler preservation and deep processing technology have played a huge role in improving the quality of deer antlers and reducing losses.

[0003] At present, due to poor palatability, unclear anti-nutritional factors and toxin residues, and unknown optimal addition ratios, the treatment methods for Chinese medicine residues are mainly stacking, burying or incineration, resulting in low resource utilization and secondary pollution to the environment. The utilization methods are mainly organic fertilizer production, biochar production, edible fungus cultivation, etc., and feed resource applications are relatively rare. Nowadays, in the process of producing Chinese medicine preparations, manufacturers are more strict and more standardized in the selection of Chinese medicinal materials, which makes the indicators of heavy metals and toxins in the Chinese medicine residues they produce far lower than those stipulated in the "Feed Hygiene Standards". Therefore, the utilization of Chinese medicine residue feed resources has a high feasibility.

[0004] At present, there are few mature technologies and cases for the industrial utilization of Chinese medicine residues in feed, and most of them are in the integrated research stage of fermentation technology and fermentation strains. Most of the research reports on the application of Chinese medicine residues in feed production are about adding a small amount to the diet formula or using it as an additive, mainly focusing on the apparent digestibility, growth performance, reproductive performance, slaughter performance, blood biochemical indicators and immune function of pigs, beef cattle, sheep and other animals. However, there are few reports on the impact of the utilization of Chinese medicine residues in feed on sika deer.

[0005] Therefore, how to reasonably utilize the Chinese medicine residues, prepare them into feed components, and apply them to the breeding of sika deer is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The purpose of the present invention is to provide a complete mixed diet fermented with Chinese medicinal residues and its application in sika deer breeding.

[0085] 2. Experimental process

[0086] A total of 39 male Shuangyang sika deer aged 3 to 4 years old were selected, with similar expected time of shedding and antler growth cycle. They were divided into three groups according to the CRD experimental design based on their age, with 13 deer in each group. Each group was kept in the same pen and fed with the FTMR diet of the corresponding group.

[0087] The trial period is 140 days, including 10 days for the pre-trial period and 130 days for the formal period. During the pre-trial period, deworming, immunization, numbering and other operations are completed.

[0090] like Figure 1 As shown, when the sika deer were fed with the FTMR particles of the present invention, Bacteroidetes, Firmicutes, Proteobacteria and Desulfobacterota were the main dominant bacteria in the rumen microorganisms at the phylum level. With the increase of the amount of traditional Chinese medicine residue added, the abundance of Firmicutes increased significantly, and the microbial diversity and abundance at the phylum level were significantly improved.

[0091] like Figure 2 As shown, when the sika deer were fed with the FTMR particles of the present invention, Bacferoidia, Clostridia, Molicutes and Spirochaetes were the main dominant bacteria in the rumen microorganisms at the class level. With the increase of the amount of traditional Chinese medicine residue added, the abundance of Clostridia increased significantly, and the microbial diversity and abundance at the class level were significantly improved.

[0092] like Figure 3As shown, when the sika deer were fed with the FTMR particles of the present invention, the rumen microorganisms at the order level were Bacteroidales, Clostridiales, Mollicules_RF9 and Spirochaetales as the main dominant bacteria. With the increase of the amount of Chinese medicine residue added, the abundance of Clostridiales increased significantly, and the diversity and abundance of microorganisms at the order level were significantly improved.

[0093] like Figure 4 As shown, when the FTMR particles of the present invention were fed, the rumen microorganisms of sika deer were mainly dominated by Prevotellaceae, Lachnospiraceae, Ruminococcus and UCG-014 at the genus level. With the increase of the amount of Chinese medicinal residue added, the abundance of Lachnospiraceae and Ruminococcus increased significantly, and the microbial diversity and abundance at the genus level were significantly improved.

[0094] (2) The number of days of sika deer off the antler plate in different experimental groups was counted, and the weight of the first antler, the second antler and the total weight of the antler were investigated. The average daily weight gain of the antler was calculated. The results are shown in Table 4.

[0096]

[0097]

[0098] As shown in Table 4, compared with the control group, feeding conventional FTMR pellets significantly shortened the number of days to leave the tray and significantly increased the average daily weight gain (g / d) and total antler production (kg / head) of sika deer antlers.

[0099] (3) The quality of velvet antlers obtained from different experimental groups of sika deer was measured. The results are shown in Table 5.

[0101]

[0102] The product of the invention makes the calcium content in the yarn slices, bone slices and powder slices higher than that of the standard sika deer two-bar antler by 116.75%, 121.11%, 80.33% and 1.72% respectively; the magnesium content is higher than that of the control group by 5.90‰, 5.08‰, 10.24‰ and 39.32‰ respectively; the potassium content is higher than that of the control group by 13.38‰, 11.41‰, 23.81‰ and 51.56‰ respectively; the zinc content is higher than that of the control group by more than 14.17%; the total amino acid content is higher than that of the control group by 18.85%, 50.86% and 70.28% respectively, but the total amino acid content in the bone slices is lower than that of the control group by 8.94%.
