Technical Field

The invention belongs to the technical field of feed preparation, and particularly relates to beef cattle feed and a preparation process thereof.

Background

The beef cattle, namely beef cattle, is a kind of cattle mainly producing beef and is characterized by full body, fast weight increment, good meat production performance and good meat quality and taste. In the process of breeding beef cattle, in order to prevent and treat the epidemic situation of a cattle group, synthetic antibiotics, synthetic hormones and sulfonamide chemical additives are generally added into feed, and after long-term use, the feed can destroy the autoimmune regulation system of the beef cattle, generate drug resistance, cause drug residues and reduce the beef quality; in addition, the traditional beef cattle feed also has the problems of poor palatability, low feed conversion rate and the like.

Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide a beef cattle feed and a preparation process thereof.

The technical scheme of the invention is summarized as follows:

the beef cattle feed comprises the following raw materials in parts by mass: 100 parts of corn flour, 50-60 parts of fermented soybean meal, 15-25 parts of puffed feather meal, 40-60 parts of wheat bran, 20-30 parts of celery juice, 0.3-0.5 part of xanthan gum, 0.05-0.2 part of rumen bypass choline, 0.1-0.4 part of rumen bypass methionine, 0.3-0.5 part of rumen bypass lysine, 1-2 parts of feed additive and 0.1-0.3 part of composite vitamin;

the feed additive comprises the following components in percentage by mass: 20-45% of mulberry leaf extract, 20-25% of chlorella extract, 20-25% of haematococcus pluvialis extract, 6-10% of saccharicterpenin, 4-10% of phytase, 3-6% of antibacterial peptide and 2-4% of rumensin.

Preferably, the compound vitamin comprises the following components in percentage by mass: 15-45% of vitamin A, 15-20% of vitamin C and vitamin D₃10-15% vitamin CBiotin E10-15%, nicotinic acid 10-15%, calcium pantothenate 5-10%, and biotin 5-10%.

A preparation process of beef cattle feed comprises the following steps:

s1: preparing celery juice: cutting fresh celery into pieces, adding water with equal mass, mixing and juicing;

s2: preparing mulberry leaf/chlorella/haematococcus pluvialis extract: crushing and pulping folium mori/chlorella/haematococcus pluvialis, adding the crushed and pulped folium mori/chlorella/haematococcus pluvialis into a 75% ethanol solution with the volume of 3-4 times, carrying out ultrasonic leaching at 25 ℃ for 2-4 hours, filtering the obtained product with double-layer gauze, adding filter residues into a 50% ethanol solution with the volume of 5-8 times, carrying out reflux extraction at 85 ℃ for 2-3 hours, combining filtrate and reflux liquid, carrying out rotary evaporation to recover ethanol, and carrying out vacuum freeze drying to obtain a folium mori/chlorella/haematococcus pluvialis extract;

s3: dissolving xanthan gum in celery juice in advance, adding corn flour, fermented soybean meal, puffed feather powder, wheat bran, rumen bypass choline, rumen bypass methionine, rumen bypass lysine, feed additive and compound vitamin, mixing, and granulating to obtain beef cattle feed.

The invention has the beneficial effects that:

1. the beef cattle feed can obviously improve the disease resistance of beef cattle, has good feed conversion rate and palatability, can obviously improve the feed intake rate of beef cattle, does not contain any chemical antibiotic, is green and safe, does not generate drug resistance, improves the autoimmune regulation system of beef cattle, and does not cause drug residue.

2. The beef cattle feed contains celery juice, and the celery has special feeding attraction fragrance, can stimulate the beef cattle to eat, improves the feed intake rate and improves the palatability; meanwhile, celery also contains rich dietary fibers and can promote gastrointestinal peristalsis and rumination of beef cattle, and active ingredients such as apigenin, flavone and coumarin derivatives and the like are contained in the celery, so that the antiviral and antibacterial performance of the beef cattle can be improved, and the immunity of the beef cattle can be improved.

3. The invention takes the fermented soybean meal and the puffed feather powder as protein sources, is easy to digest and absorb, avoids abnormal fermentation of the traditional protein raw materials in the rumen of beef cattle, and prevents the occurrence of rumen turgor. Wherein, the fermented soybean meal is a product decomposed and metabolized by microorganisms, most protein molecules are degraded into micromolecular polypeptides, oligopeptides, free amino acids and the like, and can be directly absorbed and utilized; the puffed feather powder is high-temperature puffed feather powder, and in the puffing process, the firm spatial structure and the broken disulfide bonds of the keratin are destroyed, so that the keratin fiber is changed into smaller protein subunits and linearly arranged peptide chain groups, and the keratin fiber is changed into a state of being easily digested and absorbed by beef cattle.

4. According to the invention, the mulberry leaf extract, the chlorella extract, the haematococcus pluvialis extract, the saccharicterpenin, the phytase, the antibacterial peptide and the rumensin are compounded into the feed additive, so that the disease resistance and stress resistance of beef cattle are synergistically improved, the neuroendocrine immunity and the organism oxidation resistance of the beef cattle are improved, and the feed conversion rate is improved. The mulberry leaf extract is rich in rare elements, namely organic selenium and germanium, is a natural strong antioxidant, can remove free radicals of beef cattle organisms, accelerates metabolism and discharge of toxins and wastes accumulated in the beef cattle bodies, and improves microcirculation; the chlorella extract is rich in chlorella growth factors, and can activate immunocytes, enhance the phagocytic capacity of cells, enhance the immunity of organisms, and improve the antiviral and antibacterial capacities of beef cattle; the haematococcus pluvialis extract is rich in astaxanthin and can effectively remove free radicals of organisms.
