Description

Technical Field

[0001] The invention relates to the technical field of livestock and poultry breeding, and in particular to a method for efficiently fattening beef cattle in summer and autumn under a southern pen breeding mode. Background Art

[0002] Vigorously developing the beef cattle industry and promoting the adjustment of the national animal husbandry industry structure are important measures to effectively alleviate the competition between people and animals for food, ensure the supply of meat products in my country, and promote the security of national meat product supply; people's demand for beef is constantly increasing, especially in the developed southern regions, where beef consumption is increasing year by year. The vigorous development of the beef cattle industry in the south is of great significance for the efficient use of water, heat, industrial, agricultural and sideline resources in the south. However, the climate in the south is hot and humid, and the fattening effect of beef cattle in summer and autumn is poor, the growth rate is slow, and heat stress seriously affects the health level of beef cattle. In addition, the abdominal fat rate is as high as 15%, which seriously affects the fattening effect.

[0003] In order to solve the problem of summer heat stress, the existing technology uses physical cooling to improve the comfort of beef cattle to promote health, but the cost is high, the cost performance is low, and the operability is poor, and the scope of beef cattle breeding activities is large; more importantly, even if the heat stress problem is solved, fattening beef cattle still has the technical problem of high abdominal fat rate. The use of Chinese herbal medicine extracts added to beef cattle feed can alleviate the problem of summer heat stress to a certain extent, but it cannot effectively solve the technical problem of high abdominal fat rate in fattening beef cattle in summer, and the effect of using a small amount is not ideal, and the use of a large amount significantly increases the cost and has a single function. The use of medicinal residues or other agricultural and sideline resources for fattening beef cattle in summer and autumn has a certain effect of reducing heat stress in beef cattle, but has a negative impact on the growth and meat quality of beef cattle. At the same time, with regard to reducing abdominal fat in southern beef cattle during fattening, the existing technology adopts a fermentation bed breeding mode, but this mode is not conducive to the health of beef cattle in the hot and humid climate in the south, and even causes the disease and death of cattle; at the same time, the fermentation bed is prone to dead beds, the maintenance cost of bedding is high, and the effect of reducing abdominal fat in beef cattle is limited.

[0004] Therefore, there is an urgent need for a low-cost technology that can solve heat stress and achieve efficient fattening of beef cattle and reduce the high abdominal fat rate in fattening of beef cattle in the south. In view of this, the present invention is proposed. Summary of the invention

[0005] (1) Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a method for efficient fattening of beef cattle in summer and autumn under the southern captive breeding mode, which solves the technical bottlenecks of poor health level of beef cattle due to heat stress and high abdominal fat rate and poor fattening effect in fattening of beef cattle in southern summer and autumn. Starting from the low added value of environmental pollution caused by the accumulation of industrial, agricultural and sideline resources in southern summer and autumn, the present invention achieves low-cost and efficient fattening of captive beef cattle in summer and autumn, improves breeding efficiency, and increases the added value of industrial, agricultural and sideline resources.

[0007] (3) Beneficial effects Firstly, the present invention overcomes the technical difficulty of the prior art in using Chinese herbal medicine extracts or other feed additives for fattening beef cattle to reduce the abdominal fat of beef cattle at high cost, and realizes the use of regional characteristic agricultural and sideline resources such as herbal tea residues, Chinese herbal medicine residues, distiller's grains and high-quality forage plant feed mulberry as roughage for beef cattle, without adding high-cost Chinese herbal medicine extracts or other feed additives, and from the perspective of roughage, achieves the effect of efficiently fattening beef cattle in summer and autumn and reducing the abdominal fat of beef cattle at low cost and high efficiency.

[0008] Secondly, the present invention overcomes the technical difficulty that the prior art uses only medicinal residues or other raw materials as roughage, which has poor effect in reducing abdominal fat in beef cattle. By synergizing multiple raw materials at high efficiency and low cost, the present invention achieves efficient fattening of beef cattle in summer and autumn and reduces the abdominal fat rate to 1.48%.

[0009] Thirdly, the present invention solves the technical problem that the prior art cannot achieve efficient synergistic solution to heat stress and efficient fattening of beef cattle to reduce abdominal fat of beef cattle. The above effects cannot be achieved by using medicinal residues and mulberry part of feed alone or in combination. Through efficient fermentation and coordinated use of multiple raw materials, and different technologies are adopted according to the degree of heat stress at different indoor temperatures, the goal of solving heat stress and efficiently fattening and reducing abdominal fat of southern beef cattle in summer and autumn is achieved.

[0010] Fourthly, the present invention also effectively solves the technical problems of environmental pollution caused by the accumulation of agricultural and sideline resources in summer and autumn, low added value, and high cost of efficient fattening of beef cattle in summer and autumn. Moreover, the present invention can reduce the use of concentrated feed (soybean meal, corn) in beef cattle breeding, reduce feeding costs, and help reduce the amount of soybean meal and corn in beef cattle breeding.

[0036] Table 1 Effects of different feeding methods in summer and autumn on production performance, abdominal fat rate, heat stress resistance and health status of beef cattle:

[0037] From Table 1, it can be seen that in Example 1, the abdominal fat rate is reduced to 1.48% by using the technology in this patent, and the daily weight gain, antioxidant capacity, and feed conversion rate (the lower the feed-to-weight ratio, the higher the feed conversion rate) are all the highest, and the incidence rate and heat stress are the lowest. In Examples 2-4, the same measures were taken for heat stress in different environments, and the best solution was not taken for different degrees of heat stress. It was impossible to achieve the best in efficiently reducing heat stress and promoting the growth of beef cattle and reducing abdominal fat. Although the abdominal fat rate of beef cattle was much lower than that of the control group, it was still relatively high, and the heat stress and morbidity rates increased significantly, and the health level decreased. From the comparison between Examples 2-4, it was found that the daily weight gain and feed conversion rate of beef cattle in Examples 2, 3, and 4 were gradually higher than those in the latter, but the heat stress and morbidity rates of the former were gradually lower than those in the latter. Therefore, Examples 2-4 did not achieve the organic unity of resisting heat stress, increasing growth rate and reducing abdominal fat. This shows that in order to achieve the unity of efficient fattening, reducing abdominal fat and alleviating heat stress in summer and autumn, when using feed mulberry fermentation products, herbal tea residues and composite Chinese medicine residues, adjusting the type and concentration of raw materials used and the method when the heat stress is different at different house temperatures has a significant effect.

[0038] In Example 5, since the type, concentration and fermentation method of the bacterial enzymes used in the raw material fermentation technology are different from those in Example 1, the fermentation effect is worse, the active substances and nutrients are lower, and the effects on reducing the abdominal fat of beef cattle, increasing the growth rate and resisting heat stress are worse. In the fermentation method of Example 6, the raw materials were not pretreated, and mixed fermentation was directly carried out, and the fermentation effect was also worse, the active substances and nutrients were also lower, and the effects on reducing the abdominal fat of beef cattle, increasing the growth rate and resisting heat stress were also worse. This shows that the staged fermentation of raw materials pretreatment and the efficient bacterial enzyme synergistic fermentation in the present invention have significant effects on effectively improving the fermentation effect, increasing the active substances and nutrients, thereby increasing the growth rate and heat stress resistance of beef cattle, and reducing the abdominal fat of beef cattle.

[0039] In Examples 7-9, two types of raw materials, namely, fermented mulberry, herbal tea residue, and composite Chinese medicine residue, were used to prepare roughage for feeding beef cattle. The effects of reducing abdominal fat and alleviating heat stress in beef cattle were also significantly worse than the combined use of the three types of raw materials in Example 1. A comparison between Examples 7, 8, and 9 showed that some examples had fast growth rate, high feed conversion rate, and better fattening effect for beef cattle, but poor anti-heat stress effect and high incidence rate; some examples were better in reducing heat stress and incidence rate in beef cattle, but worse in fattening beef cattle.

[0040] Example 10 uses mulberry fermentation product, and Examples 11-13 use composite Chinese medicinal residues (different combinations of Chinese medicinal residues). The effects of reducing abdominal fat and relieving heat stress in beef cattle using a single type of raw material cannot achieve the effects of the above examples, and they cannot achieve the unity of efficient fattening of beef cattle, reducing abdominal fat and keeping beef cattle healthy.

[0041] At the same time, the above embodiments significantly reduce the abdominal fat rate and improve the stress resistance of beef cattle compared with the comparative examples (including comparative example 1 using ordinary measures to reduce heat stress; comparative example 2 using a single herbal tea residue; comparative example 3 using a single feed mulberry; comparative examples 4-5 Chinese medicine residues consisting of 2 kinds without compatibility; comparative example 6 using brewer's grains); this shows that some raw materials have the effects of increasing growth rate and fattening effect, reducing abdominal fat, resisting heat stress and improving health level in fattening of beef cattle in summer and autumn, but the effect is limited, and there is a possibility that efficient synergy of heat stress resistance and efficient fattening and reducing abdominal fat cannot be achieved.

[0042] Obviously, the above embodiments are only examples for clear explanation, and are not limited to these examples. The different forms of changes made in the field are not listed here, so the derived changes are all within the protection scope of the present invention.
