Embodiment 1
[0015] Example 1 : a kind of feed additive that slows down transportation and slaughtering stress and produces adverse effects on pork quality, it is characterized in that: be made by pulverizing after mixing the raw material of following weight part: Albizia julibrissin 4 parts, Poria cocos 12 parts, Radix chinensis 6 parts, large 3 parts of fennel, 4 parts of pumpkin seeds, 3 parts of pork quality regulator, 18 parts of corn gluten meal. Wherein said pork quality regulating agent is composed of 20% magnesium sulfate, 30% magnesium aspartate, 10% vitamin E, 1% zinc glutamate and 39% yeast extract according to mass percentage.
Embodiment 2
[0016] Example 2 : a kind of feed additive that slows down transportation and slaughter stress to produce adverse effect on pork quality, it is characterized in that: it is made by pulverizing after mixing the raw material of following parts by weight: 5 parts of albizia julibrissinus, 10 parts of poria cocos, 5 parts of fennel, large 4 parts of fennel, 3 parts of pumpkin seeds, 4 parts of pork quality regulator, 19 parts of corn gluten powder. Wherein said pork quality regulating agent is composed of 20% magnesium sulfate, 30% magnesium aspartate, 10% vitamin E, 1% zinc glutamate and 39% yeast extract according to mass percentage.
Embodiment 3
[0017] Embodiment 3: animal test
[0018] Select 2,000 bred pigs with basically similar growth and development status, divide them into five groups, 400 pigs in each group, and feed the following feeds respectively 5 days before slaughter: Group 1 is the blank control group, and the basic diet is fed with the following feeds: Add 1.0wt% corn gluten meal to the weight percentage of the ration; Groups 2 and 3 are experimental groups, and add 1.0wt% of the slowing-down method described in Examples 1 and 2 in the basal ration by weight percentage of the basal ration respectively. Feed additives that are adversely affected by transportation and slaughter stress on pork quality; Groups 4 and 5 are comparative test groups, and 1.0wt% is added to the basal ration according to the weight percentage of the basal ration as described in Comparative Test Examples 1 and 2. Other feeding methods and management conditions were the same, and the pork quality after slaughter was observed. The...
