[0042] Example 1

[0043] 1. Materials and Methods

[0044] Experimental design

[0045] Nine healthy mature perinatal giraffes weighing 735±37.83kg were randomly divided into three groups, each with three animals, and each group was a replicate, namely control group (CK, supplemented with 2.5kg / d / head of concentrated feed), experimental group I (H, fed with 4kg / d / head of concentrated feed), and experimental group II (W, fed with 4kg / d / head of concentrated feed and supplemented with 1.2g / d / head of 2% capsaicin); all experimental animals were raised in single pens (8×8m 2 ).

[0046] The entire conservation experiment was conducted in a giraffe animal conservation area in Qingyuan City, Guangdong Province. The pre-feeding period was 7 days and the main trial period was 30 days. During the entire trial period, all giraffes were guaranteed free access to roughage and drinking water. Concentrated feed was supplied at 8:00am and 16:00pm respectively. During the trial, the immunization and disinfection procedures were carried out in accordance with the relevant standards of the giraffe conservation base. All experimental animals enjoyed the welfare of free exercise. The composition and nutritional level of the concentrated feed, as well as the nutritional level of the roughage (alfalfa hay) are shown in Tables 1 and 2.

[0048]

[0049]

[0050] Among them, the premix provides per kilogram of feed: VA 8000IU, VB14mg, VB23.6mg, VB540mg, VB64mg, VB120.02mg, VD33000IU, VE20IU, VK32mg, biotin 0.15mg, folic acid 1.0mg, D-pantothenic acid 11mg, niacin 10mg, antioxidant 100mg, Cu10mg, Fe80mg, Mn80mg, Zn75mg, I0.40mg, Se0.30mg.

[0053] 1.2. Test materials

[0054] Capsaicin was purchased from Guangdong Lidaer Company.

[0055] 1.3. Sample collection and indicator testing

[0056] (1) Before morning feeding on the first day of the pre-feeding period and the last day of the test period, the animals were weighed on an empty stomach. Since the food supply mode for giraffes in the nursery area is a regular and quantitative supply of concentrated feed, this embodiment only records the amount of roughage fed and the remaining amount of each giraffe every day during the test period, and the daily feed intake is counted. The results show that the average roughage intake of the control group (CK) is 16.59±2.02kg / d, the average roughage intake of the test group I (H) is 17.31±3.02kg / d, and the average feed intake of the test group II (W) is 18.07±2.41kg / d, and the P value is 0.089. Adding capsaicin can increase the feed intake of giraffes.

[0057] (2) On the last day of the experiment, 10 mL of blood was collected from the jugular vein 2 h before eating in the morning using a procoagulant blood collection tube. The blood sample was centrifuged at 3500 r / min for 15 min in a low-speed centrifuge to separate the serum, which was collected in a 1.8 mL centrifuge tube and stored at -20°C. The serum total protein (TP), albumin (ALB), globulin (GLB), total cholesterol (TC), triglycerides (TG), creatinine (CREA), urea nitrogen (BUN), blood glucose (GLU), β-hydroxybutyric acid (β-HB), and free fatty acids (NEFA) were measured. The above tests were performed using a Mindray BS-420 fully automatic biochemical analyzer and a kit produced by Biosino Biotechnology Co., Ltd. The test results are shown in Table 3.

[0058] Table 3 Blood metabolic index test results

[0059]

[0060]

[0061] Note: The P values ​​in the table are for multiple comparisons. If there is a difference between any two groups of indicators in each treatment group, P will be <0.05, the same below.

[0062] According to Table 3, the addition of only high-concentrate diets to experimental group I increased the concentration of serum albumin, but the addition of capsaicin to experimental group II reduced the albumin concentration. Capsaicin can reduce the concentration of aspartate aminotransferase. Albumin is the most abundant protein in plasma and is mainly synthesized by the liver. It plays an important role in maintaining plasma colloidal osmotic pressure, transporting a variety of metabolites, regulating the physiological effects of substances, and the body's immune function. The addition of only high-concentrate diets to experimental group I can increase the content of blood albumin. Long-term use of high-concentrate diets increases the burden on animal liver function while increasing animal energy intake. After feeding capsaicin to experimental group II, the serum albumin concentration of giraffes decreased significantly, indicating that capsaicin can reduce the risk of liver damage. The concentration of alkaline phosphatase is closely related to liver function. The decrease in alkaline phosphatase activity reduces the burden on the giraffe liver and reduces the burden on liver function.

[0063] (3) On the afternoon of the 30th day of the experiment, all experimental giraffes were restrained and induced to defecate. The fresh feces were divided into two parts. One sample was collected in a 50mL centrifuge tube and stored in a -20℃ refrigerator for the determination of fecal volatile acid. The results are shown in Table 4. The other sample was stored in a 1.8mL cryotube and immediately immersed in liquid nitrogen. The sample was then transferred to the laboratory and stored in a -80℃ refrigerator for a long time.

[0064] Table 4 Fecal volatile acid test results

[0065]

[0066] According to Table 4, there was no statistically significant difference in the contents of acetic acid, propionic acid, isobutyric acid, butyric acid, isovaleric acid and valeric acid between the control group (CK) and the experimental groups (Ⅰ and Ⅱ), and no adverse effects were produced on the hind intestine of giraffes.

[0067] (4) Take another sample preserved in step (3) and use Chao1, Observed_species, Simpson and Shannon indices to characterize richness, evenness and diversity, respectively, in order to comprehensively evaluate the α diversity of the microbial community. The results are shown in Figure 2. Figure 1 The beta diversity of the microbial community was comprehensively evaluated based on the Bray-Curtis distance algorithm. The results are shown in Figure 2 Based on LEfSe analysis, and taking LDA value greater than 2 as the threshold, the species differences between different groups were analyzed. The results are shown in Figure 3 shown.

[0068] according to Figure 1It can be seen that in the experimental group II, the Chao1 index, Observed_specie index, and Shannon index were significantly lower than those in the experimental group I (P<0.05), but there was no significant difference between the experimental group II and the control group (p>0.05). Figure 2 It can be seen that when the contribution rate of principal component 1 is 21.7% and the contribution rate of principal component 2 is 14.7%, the distance between experimental group II and experimental group I is close to that of the control group, indicating that the community composition between the groups is similar in the dimension with a principal contribution rate of 21.7%. Escherichia is a common microorganism that is widely colonized in the hind intestine of humans and other animals, but usually Escherichia can also cause diarrhea in animals. According to Figure 3 It can be seen that a total of 9 characteristic differential microorganisms were found. The markers of the control group were HUN007, Lactobacillaceae, Ligilactobacillus, and Acinetobacter. The markers of experimental group I were Faecousia, Lentisphaeria, and Escherichia. The markers of experimental group II were CAG_313. Experimental group I was fed concentrated feed, which caused an increase in Escherichia coli in the hind intestine, which would increase the risk of diarrhea in giraffes. Experimental group II ingested capsaicin, which significantly reduced the abundance of Escherichia. Capsaicin reduced potentially harmful bacteria, which may help improve intestinal health, enhance intestinal barrier function, reduce the risk of inflammation, and may have a positive effect on the immune system.

[0069] Based on the above content, it can be seen that capsaicin can increase the attractiveness or nutritional value of feed to giraffes, and will not have a negative impact on the intestinal fermentation function of perinatal giraffes. On the contrary, it will reduce the risk of liver damage caused by high-concentrate diets, reduce the burden on the giraffe's liver, and reduce the risk of intestinal inflammation. It has a positive effect on maintaining the liver health of perinatal giraffes.

[0070] Although the above embodiment describes the present invention in detail, it is only a part of the embodiments of the present invention, not all of the embodiments. People can also obtain other embodiments based on this embodiment without creativity, and these embodiments all fall within the protection scope of the present invention.
