Embodiment 1

[0015] Example 1: A feed additive for alleviating the adverse effects of transportation and slaughter stress on pork quality, characterized in that: it is made of the following raw materials in parts by weight after mixing and crushing: 4 parts of Albizia Julibrissin, 12 parts of Poria cocos, 6 parts of Rhizoma chinensis 3 parts of anise, 4 parts of pumpkin seeds, 3 parts of pork quality regulator, 18 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

[0018] Embodiment 3: animal test

[0019] 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 s...

Abstract

The invention relates to a feed additive capable of relieving unfavorable influence of transport and slaughter stress on pork quality. The invention is characterized in that the feed additive is prepared by mixing and crushing the following raw materials by weight: 3 to 5 parts of silktree flower, 9 to 15 parts of Poria cocos, 4 to 7 parts of aromatic madder, 2 to 4 parts of aniseed, 3 to 5 parts of pumpkin seed, 3 to 4 parts of a pork quality regulating agent and 10 to 25 parts of a carrier. The feed additive capable of relieving unfavorable influence of transport and slaughter stress on pork quality is used before slaughtering, can reduce occurrence the phenomena of PSE, DFD and other meat quality deterioration caused by stress in the process of slaughtering and enables the incidence rate of PSE meat and DFD meat to be obviously decreased; furthermore, feeding of the feed additive before transporting of fattened pigs enables stress caused by transporting to be alleviated, especially diarrhoea of the pigs after transporting to be alleviated and adaptive capacity of the pigs to a new environment to be improved.

Description

technical field [0001] The invention belongs to the field of feed, and relates to a feed additive for fattening pigs, in particular to a feed additive for alleviating the adverse effects of transportation and slaughter stress on pork quality. Background technique [0002] Because the breeding of high-lean meat breeds or lines has a significant negative impact on the sensory quality of pork, poor quality pork such as PSE meat (pale, soft and oozing), DFD meat (dark, hard and dry), yellow fat Meat (fat is yellow) and sour pork, etc. occur from time to time, especially under strong stress conditions of transportation and slaughter. During the period from the breeding farm to the slaughterhouse, pigs have to go through a series of processes such as fasting, water deprivation, driving, mixing, getting on, getting off and transporting before slaughtering. Stressors such as shaking, uneven speed, crowding, unfavorable temperature and unfavorable humidity can cause behavioral and p...
