Description

Technical Field

[0001] The invention belongs to the field of feed additives, and relates to a feed additive for improving the quality of meat products, and a preparation method and application thereof. Background Art

[0002] The quality issues of animal meat products have become a hot issue affecting the profits of the breeding industry. May to October each year is the peak period for quality issues of animal meat products. Pork products may have serious problems with white muscle and watery meat, which not only affects the output of pork but also reduces the taste of pork. Similar problems will also occur in poultry, beef and mutton, greatly reducing the output value of the breeding industry.

[0003] At present, the additives for improving meat quality problems are generally vitamins, organic selenium, plant extracts, etc. The starting point of these solutions is to help animals remove free radicals in the body and control the meat quality problems caused by further deterioration due to stress, which can reduce meat quality problems to a certain extent. However, since the sensitivity of animals to stressors and the number of free radicals produced by animals are not fundamentally reduced, it is difficult to guarantee the stability of the effects and the degree of improvement of the above additives for meat quality problems caused by breed or environmental stress. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology and provide a feed additive for improving the quality of meat products and a preparation method and application thereof.

[0005] In order to solve the above technical problems, the technical solution proposed by the present invention is: A feed additive for improving the quality of meat products, wherein the raw materials thereof include the following components by weight: 10-50 parts of organic trace elements, 5-30 parts of inorganic magnesium minerals, 20-60 parts of functional raw materials and 2-10 parts of carriers; the functional raw materials include any one or more of magnesium threonate, magnesium hydroxymethionine and manganese nicotinate.

[0006] In the above feed additive, preferably, the organic trace elements include any one or more of hydroxymethionine copper, hydroxymethionine iron, hydroxymethionine zinc, hydroxymethionine manganese, hydroxymethionine chromium, methionine copper, methionine iron, methionine zinc, methionine manganese, methionine chromium, glycinate copper, glycinate iron, glycinate zinc, glycinate manganese, threonine copper, threonine iron, threonine zinc, threonine manganese, protein copper, protein iron, protein zinc, protein manganese, yeast chromium and yeast selenium. These organic trace elements can increase the anti-oxidative stress ability of the animal body, such as organic zinc source, organic manganese source and yeast selenium are all involved in the synthesis and function of antioxidant enzymes such as SOD enzyme, metallothionein and glutathione peroxidase in the body, and greatly improve the anti-oxidative stress ability of the animal body through various ways.

[0007] Preferably, the inorganic magnesium minerals include any one or more of magnesium oxide, magnesium sulfate and magnesium chloride. These inorganic magnesium minerals can inhibit excessive nerve excitement to a certain extent, reduce the production of mineralocorticoids and catecholamine hormones in animals, and further reduce the production of oxidative free radicals caused by external stimuli in animals.

[0008] Preferably, the functional raw materials are magnesium hydroxymethionine and manganese nicotinate. The combination of these functional raw materials such as manganese nicotinate and manganese hydroxymethionine can promote the conversion of nutrients in feed from synthetic fat to synthetic protein by increasing the activity of pyruvate carboxylase, thereby promoting the synthesis of lean meat and reducing the synthesis of fat.

[0009] Preferably, the carrier is any one or more of medical stone, zeolite powder, stone powder and rice husk powder.

[0010] Compared with the existing technology, the feed additive of the present invention has the advantage that the present invention controls the generation of oxidative free radicals from the source, rather than increasing the scavenging ability of the animal body by waiting for the generation of free radicals. This function has a good effect on improving the meat quality of animal species prone to meat quality problems and animals in relatively abnormal environments.

[0011] Based on a general inventive concept, the present invention provides a method for preparing the above feed additive, comprising the following steps: (1) The organic trace elements are sieved through a 40-200 mesh sieve and mixed evenly to obtain a small package 1 for later use; (2) The inorganic magnesium mineral is passed through a 40-200 mesh sieve and mixed evenly with the small package 1 to obtain the small package 2 for standby use; (3) After the functional raw material is passed through a 40-200 mesh sieve, it is mixed evenly with 1 / 3 to 2 / 3 of the carrier to obtain a small package 3 for standby use; (4) The remaining carrier is added to the small package 2 obtained after step (2) and the small package 3 obtained after step (3), and the mixture is evenly mixed to obtain a feed additive.

[0012] In the above preparation method, preferably, in step (1), step (2) and step (3), the mixing time is 150-300 seconds; and in step (4), the mixing time is 15-25 minutes.

[0013] Based on a general inventive concept, the present invention also provides an application of the above-mentioned feed additive, which is used to prepare animal feed for livestock, poultry or ruminants, specifically animal feed for growing and fattening pigs, yellow-feathered broilers, white-feathered broilers, beef cattle or sheep.

[0014] In the above application, preferably, the amount of the feed additive added to each ton of livestock feed is 0.5-1.0 Kg; the amount of the feed additive added to each ton of poultry feed is 0.3-1.0 Kg; and the amount of the feed additive added to each ton of ruminant feed is 0.5-1.0 Kg.

[0015] The application of the above feed additive in the preparation of livestock, poultry or ruminant feed can effectively improve the feed conversion of animals, reduce the feed-to-meat ratio, effectively reduce the fat content and drip loss of animal carcasses after slaughter, and effectively improve the meat color of animal carcasses after slaughter.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The feed additive of the present invention contains inorganic magnesium minerals which can inhibit excessive nerve excitement to a certain extent, reduce the production of mineralocorticoids and catecholamine hormones in animals, and further reduce the production of oxidative free radicals in animals due to external stimuli; organic trace elements can increase the anti-oxidative stress ability of animals, such as organic zinc sources, organic manganese sources, and yeast selenium, which are involved in the synthesis and function of antioxidant enzymes such as SOD enzymes, metallothioneins, and glutathione peroxidase in the body, and greatly improve the anti-oxidative stress ability of animals through various pathways; functional raw materials such as nicotinic acid manganese and hydroxymethionine manganese can promote the conversion of nutrients in feed from synthetic fat to synthetic protein by increasing the activity of pyruvate carboxylase, promote the synthesis of lean meat, and reduce the synthesis of fat; overall, it can improve the quality of animal carcasses, increase feed remuneration, and reduce meat production costs.

[0017] 2. The feed additive of the present invention is used for feeding livestock, poultry or ruminants. Compared with the existing technology, the advantage is that the generation of oxidative free radicals is controlled from the source, rather than waiting for the generation of free radicals to increase the scavenging ability of the animal body. The prepared feed additive product can improve the meat color grade of beef cattle and reduce drip loss. It has a good meat quality improvement effect on animal breeds prone to meat quality problems and animals in abnormal environments.

[0029] Application Example 1: Animal experiment on improving the quality of white-feathered broiler meat 1000 double AA broilers were randomly divided into four treatments, each with 5 replicates and 50 broilers in each replicate. Treatment 1 did not add the feed additive prepared by the present invention, and treatments 2 to 4 added 0.3 kg / T, 0.65 kg / T, and 1.0 kg / T of the feed additive prepared by Example 1 of the present invention, respectively. The broilers were fed from 22 days of age until market release, and the test period was 21 days. After 42 days of age, the broilers and the consumed feed were weighed, and the effects on the final body weight, feed-to-meat ratio, survival rate, and abdominal fat rate were compared. The test results are shown in Table 1: Table 1: Effects of different amounts of feed additives on the quality of white-feathered broiler meat

[0030] From the test results in Table 1, it can be seen that adding the feed additive product of the present invention can improve the feed-to-meat ratio, the drip loss of broilers after slaughter and reduce the abdominal fat rate. The best effect of improving the feed-to-meat ratio can be achieved by adding 0.3 kg of the feed additive product prepared by the present invention. For the improvement of drip loss and abdominal fat rate, the effects of adding 0.3 kg and 0.65 kg of the feed additive product prepared by the present invention are equivalent. Adding 1 kg of the feed additive product prepared by the present invention is better than the other two addition groups.

[0031] Application Example 2: Animal test on improving the quality of medium-speed yellow-feathered rooster meat 1000 57-day-old medium-speed Lingnan yellow jade broiler chickens were randomly divided into four treatments, each treatment had 5 replicates, and each replicate had 50 broilers. Treatment 1 did not add the feed additive product prepared by the present invention, and treatments 2 to 4 added 0.3 kg / T, 0.65 kg / T, and 1.0 kg / T of the feed additive product prepared by the present invention, respectively. The broilers were fed from 57 days to 84 days of age, and the test period was 28 days. After 84 days of age, the broilers and the consumed feed were weighed, and the effects on the final body weight, feed-to-meat ratio, survival rate, and abdominal fat rate were compared. The test results are shown in Table 2: Table 2: Effects of different amounts of feed additives on the quality of yellow-feathered rooster meat

[0032] From the test results in Table 2, it can be seen that adding the feed additive product prepared by the present invention can improve the drip loss of yellow-feathered broilers after slaughter and reduce the abdominal fat rate, and the feed-to-meat ratio of yellow-feathered broilers has a downward trend. The improvement effect of the feed-to-meat ratio has a downward trend when 0.3Kg is added. The effects of adding 0.3Kg and 0.65Kg of the feed additive product prepared by the present invention on the improvement of drip loss and abdominal fat rate are equivalent, and the effect of adding 1Kg of the feed additive product prepared by the present invention is better than the other two addition groups.

[0033] Application Example 3: Animal Test for Improving the Quality of Growing and Fatten Pork Thirty Duchangdawai Sanyuan pigs with an initial body weight of 91.5Kg±0.5Kg were randomly divided into three treatments, with 10 pigs in each treatment. Group 1 was the control group, which was added with the feed additive product prepared by the present invention. Groups 2-3 were added with 0.5Kg / T and 1.0Kg / T of the feed additive product prepared by the present invention, respectively. The test period was 30 days, and the production performance of each group, back fat at point p2 and meat quality related indicators were tested respectively. The test results are shown in Table 3: Table 3: Effects of different amounts of feed additives on the quality of growing and fattening pork

[0034] Note: L is the brightness index of meat, and A is the redness index.

[0035] From the test results in Table 3, it can be seen that the feed additive product prepared by the present invention has a significant effect on reducing the feed-to-meat ratio and improving the back fat at the p2 point, and the effect of adding 1.0Kg of the feed additive product prepared by the present invention is more obvious than that of adding 0.5Kg of the feed additive product prepared by the present invention. From the results of improving meat color and drip loss, adding 0.5Kg of the feed additive product prepared by the present invention is effective, but adding 1.0Kg of the feed additive product prepared by the present invention is more significant.

[0036] Application Example 4: Animal experiment on improving the quality of mutton 24 F1 mutton sheep of Durbin × Han hybrid weighing about 20 kg were selected and randomly divided into two groups, each with 8 sheep (half male and half female). The three groups were raised separately, one group was fed without adding the feed additive product prepared by the present invention, and the second and third groups were fed with 0.5 kg and 1.0 kg of the feed additive product prepared by the present invention, respectively. The test period was 150 days, and the daily weight gain, feed-to-meat ratio, and related indicators of meat color and drip loss after slaughter were observed throughout the whole period. The test results are shown in Table 4: Table 4: Effects of different amounts of feed additives on mutton quality

[0037] From the test results in Table 4, adding the feed additive product prepared by the present invention can improve the feed return of goats and reduce abdominal fat, and can effectively improve the meat color grade and reduce drip loss. From the effect, the effect of adding 1.0 kg of the feed additive product prepared by the present invention is better than that of adding 0.5 kg.

[0038] Application Example 5: Animal Test for Improving Beef Quality 36 beef cattle aged 6-8 months with an average weight of about 210 kg were selected and randomly divided into three groups, each with 12 cattle. One group was fed without the feed additive product prepared by the present invention, and the second and third groups were fed with 0.5 kg and 1.0 kg of the feed additive product prepared by the present invention, respectively. The test period was 120 days, and the daily weight gain, feed-to-meat ratio, and meat color and drip loss related indicators after slaughter were observed throughout the whole period. The test results are shown in Table 5: Table 5: Effects of different amounts of feed additives on beef quality

[0039] From the test results in Table 5, it can be seen that adding 0.5 kg of the feed additive product prepared by the present invention to beef cattle feed can reduce the feed-to-meat ratio and correspondingly reduce the backfat thickness. In terms of improving the quality of meat products, adding 0.5 kg of the feed additive product prepared by the present invention can improve the meat color grade of beef cattle and reduce drip loss. The test results show that the effect of adding 1.0 kg is better than that of 0.5 kg.
