[0032] 1.1.4 Experimental Design

[0033] Sixty Tan lambs were randomly divided into three groups: a control group, experimental group I, and experimental group II, with 20 lambs in each group and an equal number of males and females. In addition to freely moving in the pen every day, the experimental lambs in group I carried out aerobic exercise of 8 - 10 km along the ecological ranch running track, and those in group II carried out aerobic exercise of 4 - 6 km along the ecological ranch running track. The control group only moved freely in the pen every day. Each group of experimental lambs wore a Beidou locator to record the daily movement trajectory and walking distance. The experimental period was 6 months, and each group of experimental lambs used a Beidou movement trajectory recorder to record their daily exercise volume. During the experimental period, the daily feeding amount and nutritional composition of the experimental lambs in each group were exactly the same. During the experiment, the growth performance, blood routine, blood biochemical indexes, immune and antioxidant performance indexes of the experimental lambs were measured to analyze the effects of aerobic exercise volume on the above indexes of the experimental Tan sheep. The composition and nutritional level of the basal diet are shown in Table 1.

[0034] Table 1 Composition and nutritional level of the basal diet (air-dried basis)

[0035]

[0036] Note: The premix provided 8,000 IU of vitamin A, 1,000 IU of vitamin D, 20 IU of vitamin E, 46.8 mg of copper sulfate pentahydrate, 2.88 mg of calcium iodate, 257.22 mg of ferrous sulfate monohydrate, 130.5 mg of manganese sulfate monohydrate, 1.44 mg of cobalt chloride hexahydrate, 135.54 mg of zinc sulfate monohydrate, and 71.84 mg of yeast selenium per kilogram of diet; the metabolizable energy in the nutritional level was a calculated value, and the rest were measured values, and the measured values were determined with reference to the references.

[0037] 1.1.5 Determination of indexes

[0038] 1.1.5.1 Determination of growth indexes

[0039] On the first and last days of the experiment, the lambs in each group were weighed on an empty stomach and recorded as the initial weight and final weight respectively; the daily feed intake of each group of experimental lambs was recorded, and the average daily gain, average daily feed intake, feed-to-gain ratio, etc. were calculated. Feed intake = amount of feed fed - amount of feed remaining in the trough, average daily gain = (final weight - initial weight) / number of experimental days, average daily feed intake = sum of daily feed intakes during the experimental period / (number of experimental days × 20), feed-to-gain ratio = average daily feed intake / average daily gain.

[0040] 1.1.5.2 Determination of blood routine and blood biochemical indexes

[0041] On the day when the experiment ended, 10 mL of whole blood was collected from the jugular vein of the experimental sheep in each group, and was respectively filled into a 5 mL anticoagulant tube and a 5 mL coagulant-promoting tube. The anticoagulated blood was stored at 4 °C for standby; the coagulant-promoting blood was allowed to stand at room temperature for 30 min, centrifuged at 2000 r / min for 5 min, and the serum was stored at -20 °C for standby. An automatic five-category animal blood cell analyzer was used to measure the indicators of white blood cells, neutrophils, lymphocytes, monocytes, eosinophils, basophils, red blood cells, hemoglobin, hematocrit, mean corpuscular volume, mean hemoglobin concentration, platelets, mean platelet volume, and plateletcrit in the anticoagulated blood. An automatic biochemical analyzer was used to measure the serum biochemical indicators, including alanine aminotransferase, aspartate aminotransferase, aspartate aminotransferase / alanine aminotransferase, alkaline phosphatase, γ-glutamyl transferase, total protein, albumin, globulin, albumin / globulin ratio, urea, creatinine, uric acid, glucose, total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, lactate dehydrogenase, creatine kinase, creatine kinase isoenzyme, total bile acid and other indicators.

[0042] 1.1.5.3 Determination of serum immune factors, vitamins and antioxidant indicators

[0043] ELISA kits were used to measure the indicators of interleukin 2, interleukin 3, interleukin 5, interleukin 6, interleukin 8, immunoglobulin A, immunoglobulin E, immunoglobulin M, vitamin A, vitamin D, vitamin E, endothelin, superoxide dismutase, glutathione peroxidase, urinary amylase, apolipoprotein A, apolipoprotein B, total antioxidant capacity, malondialdehyde, etc.

[0044] 1.1.6 Statistical analysis of data

[0045] Excel 2007 software was used to preprocess the experimental data, and SPSS 25.0 software was used to conduct a normal distribution test on the experimental data. The experimental data that conformed to the normal distribution were subjected to one-way analysis of variance, and the LSD method was used for multiple comparisons of the differences between groups. The results were expressed as "mean ± standard deviation". P < 0.01 indicated extremely significant differences, P < 0.05 indicated significant differences, and P > 0.05 indicated no significant differences.

[0070] 1.3 Discussion

[0071] 1.3.1 Effects of aerobic exercise on the growth performance of Tan sheep

[0072] Body weight is an important indicator for evaluating the growth performance of livestock and poultry. The research results of J.A. Hawley et al. show that exercise has an impact on the growth performance of chickens. The research results of B. Strasser et al. show that the number of argentaffin cells in each part of the small intestine of mice increases significantly after aerobic exercise. Argentaffin cells can secrete gastrointestinal hormones that play an important regulatory role in physiological processes such as digestion and absorption. It can be seen that aerobic exercise can enhance the intestinal absorption capacity of nutrients. This study found that the average daily gain and feed-to-weight ratio of Group I in the experiment were better than those of Group II and the control group, which is consistent with the research results of Zhang Xingxing et al. who found that grazing Charolais cattle have higher growth performance, indicating that aerobic exercise of 8 - 10 km per day can enhance the ability of Tan sheep to digest and absorb nutrients in the intestine, improve feed utilization rate and the growth performance of Tan sheep during the fattening period.

[0073] 1.3.2 Effects of aerobic exercise on the blood routine of Tan sheep

[0074] Blood routine examination is the main method to observe the changes in the components and morphological distribution of blood cells in animals. Granulocytes in white blood cells are one of the important components of the body's immune defense system. This study found that the contents of eosinophils, platelets, and plateletcrit in the blood cells of Tan sheep in Group I (Tan sheep with 8 - 10 km of aerobic exercise per day) were higher than those in Group II. Higher levels of eosinophils, platelets, and plateletcrit improved the immune response and tissue regeneration and repair ability of Tan sheep during the fattening period and reduced the inflammatory response. This result is consistent with the research results of Luo Jun et al. that aerobic exercise can improve the systemic low-grade inflammatory response in elderly patients with stable angina pectoris. Aerobic exercise can also promote the synthesis and release of nitric oxide (NO), inhibit platelet aggregation and the synthesis of endothelin, and reduce the formation of thrombus. This study found that the mass concentration of endothelin in the serum of Tan sheep in Group I was extremely significantly lower than that in the control group, indicating that aerobic exercise of 8 - 10 km per day can reduce the synthesis of endothelin in the serum. It has been found that excessive exercise will cause the weakening of the red blood cell clearance function and affect the normal immune function. There was no significant difference in the red blood cell content among the three groups in this experiment. From the results of the blood routine examination in this experiment, it can be seen that 8 - 10 km of exercise per day for Tan sheep during the fattening period is a relatively appropriate amount of exercise.

[0075] 1.3.3 Effects of aerobic exercise on the blood biochemical indexes of Tan sheep

[0076] The levels of blood biochemical indicators can reflect the animal's nutritional metabolism and the health status of the body. This study found that aerobic exercise of 8-10 km per day for fattening Tan sheep can reduce the mass concentrations of blood biochemical markers urea and triglyceride, and increase the blood glucose concentration. The mass concentration of urea in serum is mainly affected by kidney function, protein intake, and catabolism. The research results of Li M.M. et al. and P.R. Beatson et al. showed that the serum urea mass concentration can accurately reflect the protein metabolism and amino acid balance in the body. Guo Rong et al. found that when the body's utilization and synthesis of protein accelerate and the amino acid utilization rate increases, the serum urea mass concentration will decrease accordingly. Clinically, the level of blood glucose content is used as one of the important indicators for judging the health of the body. The long-term high level of triglyceride concentration in serum is closely related to excessive body fat. Excessive adipose tissue will also develop chronic inflammation and release a large amount of inflammatory mediators into the blood, causing the occurrence of obesity-related metabolic diseases. In this experiment, the blood triglyceride concentration of the control group of Tan sheep was 0.22 μmol / L, and the blood triglyceride concentrations of Tan sheep with aerobic exercise of 4-6 km and 8-10 km per day were 0.14 and 0.11 μmol / L respectively. Under the condition of the same daily ration feeding amount and nutritional components, the blood triglyceride concentration of Tan sheep with aerobic exercise of 8-10 km per day was only 50% of that of the control group. The research results of Chen J et al. showed that moderate-intensity training can significantly improve the blood lipid metabolism of obese people. Both triglyceride and glucose in serum are converted in the animal liver. In this experiment, the triglyceride in the serum of the experimental group I of Tan sheep was significantly lower than that of the control group, while the glucose concentration (1.89 μmol / L) was much higher than that of the control group (1.21 μmol / L), indicating that aerobic exercise of 8-10 km per day can improve the liver metabolic function of fattening Tan sheep, improve blood glucose and blood lipid metabolism, and increase the protein synthesis amount.

[0077] 1.3.4 Effects of aerobic exercise on blood immune factors, vitamins and antioxidant indexes of Tan sheep

[0078] Animal blood immune factors and antioxidant indexes can reflect the health level of the animal body. I. Vogiatzis et al. found that aerobic exercise can change the blood biochemical indexes and inflammatory factor levels in the human body, thus affecting human health. Zeng Yungui found that aerobic exercise can improve the proliferation ability of rat spleen lymphocytes, inhibit the excitability of the sympathetic nerve regulation pathway in the rat spleen, and regulate the secretion of stress hormones and neurotransmitters, thereby enhancing the body's immunity. This study found that compared with the control group, the mass concentrations of interleukin-2 and immunoglobulin in the blood of fattening Tan sheep that performed 8 - 10 km and 4 - 6 km of aerobic exercise per day were extremely significantly increased, while the mass concentrations of interleukin-5, interleukin-6, interleukin-8, and endothelin were extremely significantly decreased. Interleukin-2 is a polypeptide immune enhancer mediated by T cells, which can induce the secretion of interferon and various cytokines in the body, promote the differentiation of immune cells, and enhance the body's immunity. Xu Ping found that the method of grazing plus supplementary feeding can increase the mass concentrations of interleukin-2 and immunoglobulin in calves, which is consistent with the results of this experiment. J. Sarparanta et al. found that aerobic exercise can reduce the levels of pro-inflammatory factors in experimental mice. M. L. Moy et al. found that appropriate exercise can reduce the level of interleukin-6 in the serum of patients with chronic obstructive pulmonary disease. In this experiment, the concentration of triglyceride in the blood of fattening Tan sheep in the control group was significantly higher than that in experimental group Ⅰ, resulting in enhanced body fat oxidation metabolism in the control group Tan sheep, increased secretion of inflammatory factors interleukin-6 and interleukin-8, and at the same time stimulating the transcription of preproendothelin, causing a large release of endothelin and an increased risk of cardiovascular system diseases. It can be seen that aerobic exercise per day in fattening Tan sheep can reduce the content of pro-inflammatory factors and endothelin in the body, increase the content of anti-inflammatory factors and immunoglobulins, reduce the inflammatory reaction in the body, and avoid the occurrence of diseases.

[0079] Vitamins are essential organic compounds for the nutrition and growth of humans and animals, and play an important role in the body's metabolism, growth, development, and health. This study found that compared with the control group, the contents of vitamin A, vitamin D, and vitamin E in the blood of fattening Tan sheep that performed 8 - 10 km and 4 - 6 km of aerobic exercise per day were extremely significantly increased. Song G. et al. found that exercise plays a positive role in the absorption of nutrients and energy metabolism in the animal intestine. Although the mechanism of action is still under study, regular moderate-intensity aerobic exercise can increase the digestion and absorption of nutrients and vitamins in the animal intestine. R. Jorde et al. found that the mass concentration of vitamin D in the serum is negatively correlated with the concentration of triglyceride. It can be seen that obesity can affect the mass concentration of vitamins in the serum. This study found that the serum amylase concentration in the experimental group of Tan sheep was extremely significantly higher than that in the control group, indicating that aerobic exercise can improve pancreatic function, increase the secretion of amylase, and thus increase the amylase concentration in the blood.

[0080] Antioxidants refer to any substances that can effectively inhibit free radical oxidation reactions even at low concentrations. They can directly and indirectly consume free radicals to counteract the oxidative attack of free radicals on animal cells. The stronger the body's antioxidant capacity, the healthier it is. This study found that compared with the control group, the activities of antioxidant substances superoxide dismutase and glutathione peroxidase and the total antioxidant capacity in the blood of fattening Tan sheep that performed aerobic exercise of 8 - 10 km and 4 - 6 km per day were extremely significantly increased. After the Tan sheep were fattened in the drylot, excessive fat deposition in the body led to an increase in lipid peroxidation expression, triggering an inflammatory response and generating excessive free radicals. The expression of enzymes such as serum superoxide dismutase and glutathione peroxidase was too low, breaking the homeostasis between free radical production and elimination in the body. Therefore, sufficient superoxide dismutase, glutathione peroxidase, etc. in the body can help maintain the free radical homeostasis. This study also found that the concentration of the oxidative stress product malondialdehyde also increased with the increase in antioxidants, indicating that aerobic exercise during the fattening period of Tan sheep can improve the body's antioxidant performance and the homeostasis of the antioxidant system. The reason may be that aerobic exercise can help the body cope with antioxidant stress by increasing the activity of antioxidant enzymes, thereby increasing the production of antioxidant substances in the body, maintaining the homeostasis of the body's antioxidant system, and improving the body's health level.

[0081] In summary, aerobic exercise of 8 - 10 km per day for fattening Tan sheep improved the growth performance of Tan sheep, enhanced the activity of blood cells, the digestive and absorption capacity of the intestine for nutrients and fat-soluble vitamins, and the liver metabolism function, and improved the blood glucose and lipid metabolism capacity; reduced the content of serum pro-inflammatory factors, increased the content of anti-inflammatory factors, immunoglobulins, antioxidants and amylase, and played an important role in maintaining the homeostasis of the antioxidant system of fattening Tan sheep, reducing the inflammatory reaction in the body, inhibiting the excitability of the sympathetic nerve, regulating the secretion of glandular hormones, and preventing the occurrence of diseases in fattening Tan sheep, providing technical support for the production of high-quality, healthy and green Tan mutton.

[0082] The above experiments proved that the present invention can effectively evaluate the influence of aerobic exercise factors on the growth performance of Tan sheep by analyzing the growth performance of Tan sheep using blood big data.

[0083] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
