Problems solved by technology

At the same time, transportation stress puts the livestock and poultry body in a strong stress state, which intensifies the energy metabolism and lipid peroxidation process of the skeletal muscle, the rapid accumulation of lactic acid in the muscle, the pH value changes, and the meat quality is reduced.

Embodiment 1

[0047] Liquidambar leaves were ultrafinely pulverized to 5 μm, and then mixed with chitosan and water at a ratio of 1g:0.4g:15mL for 5h at 55°C to remove the precipitate, and then sequentially used 20wt%, 40wt% and 60wt% Eluted with ethanol solution, collected the eluent, and dried to obtain the extract of liquidambar gum leaves.

[0048] Separately pulverize liquidambar leaf extract, wolfberry polysaccharide, stachyose, burdock oligosaccharide, yeast iron and diatomaceous earth and pass through a 100-mesh sieve. Mix 0.05 parts by weight of Bifidobacterium longum, 0.05 parts by weight of Lactobacillus fermentum, 0.1 parts by weight of Clostridium butyricum and 0.2 parts by weight of the above-mentioned diatomaceous earth to obtain the first mixture. Mix 0.2 parts by weight of the above-mentioned sweetgum gum leaf extract, 1 part by weight of the above-mentioned Lycium barbarum polysaccharide, 0.05 parts by weight of the above-mentioned yeast iron and part of the carrier to obt...

Embodiment 2

[0052] The difference between this embodiment and Example 1 is that each raw material ratio is 0.4 parts by weight of liquidambar leaf extract, 2 parts by weight of Lycium barbarum polysaccharide, 15 parts by weight of stachyose, 15 parts by weight of burdock oligosaccharide, 0.1 parts by weight Bifidobacterium longum, 0.1 part by weight of Lactobacillus fermentum, 0.2 part by weight of Clostridium butyricum, 0.4 part by weight of diatomaceous earth, 0.1 part by weight of yeast iron and 66.7 parts by weight of carrier.

Embodiment 3

[0054] The difference between this embodiment and Example 1 is that each raw material ratio is 0.6 parts by weight of liquidambar leaf extract, 3 parts by weight of Lycium barbarum polysaccharide, 20 parts by weight of stachyose, 20 parts by weight of burdock oligosaccharide, 0.15 parts by weight Parts by weight of Bifidobacterium longum, 0.15 parts by weight of Lactobacillus fermentum, 0.3 parts by weight of Clostridium butyricum, 0.6 parts by weight of diatomaceous earth, 0.15 parts by weight of yeast iron and 55.05 parts by weight of carrier.

Abstract

The invention relates to a pre-slaughter feed additive for relieving fattening pig transportation stress and improving meat quality, a preparation method and an application, and belongs to the field of feed. The feed additive comprises Chinese sweet gum leaf extracts, lycium barbarum polysaccharide, stachyose, burdock oligosaccharide, bifidobacterium longum, lactobacillus fermenti, clostridium butyricum, diatomite, yeast iron and the rest carriers. Selected components of the feed additive are safe and free from hazard residues and drug resistance and have synergistic complementation, matched use effects are good, the transportation stress is relieved, and the meat quality is improved. The preparation method of the additive includes the step: mixing the raw materials according to matching ratio. The method is simple and rapid, good in condition controllability. The feed additive is used for preparing fattening pig feed, appetite and growth performances of fattening pigs can be improved,intestinal flora balance is maintained, the meat colors and the meat quality of the fattening pigs are improved, and transportation stress response of the fattening pigs is relieved, and the slaughtering meat quality after transportation is ensured.

Description

technical field [0001] The invention relates to the field of feed, and in particular to a pre-slaughter feed additive for alleviating the transportation stress of fattening pigs and improving meat quality, as well as its preparation method and application. Background technique [0002] In recent years, through measures such as genetic breeding, high-quality compound feed, and environmental condition control, the pork production in my country has been greatly increased, which can fully meet people's demand for pork. However, driven by the current breeding goals and feeding concepts such as high growth rate, high carcass lean meat percentage and low feed-to-meat ratio, some pork quality traits have gradually deteriorated. At the same time, with the continuous improvement of living standards and consumption levels, people pay more and more attention to the quality of pork. [0003] Transportation stress is one of the most important stress factors in animal husbandry production...
