Abstract
The invention discloses a compound feed additive for fattening beef cattle and a preparation method thereof, relates to the field of feed additives, and is composed of a feed additive at the early fattening stage and a feed additive at the later fattening stage. The functional fattening beef cattle feed additive provided by the invention can effectively prevent and treat subacute rumen acidosis and improve the economic benefit of beef cattle, and is particularly important. The invention provides a compound feed additive for fattening beef cattle and a preparation method thereof, which are mainly used for preventing subacute rumenic acidosis at the early fattening stage, promoting the quick fattening effect at the early fattening stage, improving the calcium and magnesium levels of beef cattle at the late lactation stage and improving the beef quality. Compared with the prior art, the composite additive disclosed by the invention can improve the liver injury caused by high concentrated feed at the early fattening stage, improve the immunity and oxidation resistance level of the organism, improve the calcium and magnesium content of beef cattle, obviously improve the daily gain of the beef cattle at the fattening stage, and has obvious economic benefit.
Description
The technical field is as follows:
the invention relates to the field of feed additives, in particular to a compound feed additive for fattening beef cattle and a preparation method thereof.
Background art:
the beef cattle breeding industry in China is developing in a large-scale, intensive and ecological circulating breeding direction, and is one of the fastest-developing industries in the livestock industry at present. The feed additive is an important component of daily ration of beef cattle, and is particularly important for developing products capable of improving the feed utilization efficiency and promoting the quick fattening of beef cattle in a plurality of fattening beef cattle feed additives, because the feed cost occupies most of the production cost of animals, the production cost can be effectively reduced by reducing the feed cost, and the aims of cost saving, efficiency improvement and quick development of the industry are fulfilled. Therefore, the additive is scientifically and reasonably used, so that the production cost can be reduced, and the incidence rate of diseases easy to occur and nutritional metabolic diseases in beef cattle production can be prevented, so that the overall economic benefit of beef cattle producers is improved, and the healthy development of the beef cattle industry is promoted. In the management of fattening beef cattle, the addition of high concentrated feed at the early fattening stage is very easy to cause the occurrence of subacute rumenic acidosis of the beef cattle, and the quick fattening effect of the beef cattle is seriously influenced; the beef quality can be effectively improved and the economic benefit can be improved through the feed addition in the later fattening period.
The invention content is as follows:
in view of the current situation of beef cattle breeding, the development of a functional fattening beef cattle feed additive which can effectively prevent and treat subacute rumen acidosis and improve the economic benefit of beef cattle is particularly important. The invention provides a compound feed additive for fattening beef cattle and a preparation method thereof, which are mainly used for preventing subacute rumenic acidosis at the early fattening stage, promoting the quick fattening effect at the early fattening stage, improving the calcium and magnesium levels of beef cattle at the late lactation stage and improving the beef quality.
The technical scheme for solving the technical problems is as follows:
the invention relates to a fattening beef cattle compound additive, which consists of a feed additive at the early fattening stage and a feed additive at the later fattening stage;
the feed additive for the early fattening period is prepared by mixing the following components in parts by weight: 5-15 parts of initial mixed material, 1-5 parts of amylase and 1-5 parts of selenium yeast;

1. laboratory animal
In an intensive thousand-head cattle farm, 14 healthy Simmental beef cattle are selected according to the principle that the ages, body conditions and the fetal times are similar, and randomly divided into two groups, wherein each group comprises 7 cattle. The experimental group had 7 heads, and the control group had 7 heads. The experimental group is fed with 20 g/head/day of the feed additive at the early fattening stage, 20 days, 20 g/head/day of the feed additive at the later fattening stage, 20 days, and 60 days in the whole experimental period on the basis of feeding the basic ration.
2. Sample collection
The experimental group and the control group collect 10ml of tail root vein blood collected 7d, 20 days and 60 days after the experiment is started respectively, centrifuge for 10min at the room temperature of 4000 gamma-pm/min to separate serum, and detect indexes of serum alanine Aminotransferase (ALT), aspartate Aminotransferase (AST), Total Protein (TP), Albumin (ALB), Globulin (GLO), urea (U gamma-ea), Malondialdehyde (MDA), glutathione peroxidase activity (GSH-Px), magnesium (Mg) and calcium (Ca) by using a biochemical analyzer. And recording the initial and final weights of the beef cattle experiment.
3. Data processing
Data analysis was performed using the sps 19.0 data processing software and results are expressed as "mean ± standard deviation".
4. Results of the experiment
The influence on the main biochemical indexes and the weight increment of the beef cattle is shown in tables 1 and 2:
TABLE 1 Effect on biochemical indicators of beef cattle blood (3d)
Note that shoulder marks indicate significant differences (P < 0.05), that shoulder marks indicate very significant differences (P < 0.01), and that no shoulder marks indicate insignificant differences (P > 0.05) compared to the control group.
TABLE 2 Effect on beef cattle weight gain (7d)
Note that shoulder marks indicate significant differences (P < 0.05), that shoulder marks indicate very significant differences (P < 0.01), and that no shoulder marks indicate insignificant differences (P > 0.05) compared to the control group.
5. Analysis of test results
From the analysis results of the indexes, compared with a control group, after the health-care granules are fed for 20 days, the content of aspartate aminotransferase of the beef cattle is obviously lower than that of the control group, the levels of total protein, globulin and GSH-Px are obviously higher than that of the control group, and the average of the blood calcium and blood magnesium levels of the beef cattle at the end of fattening is higher than that of the control group.
