Abstract
The invention provides a pig feed additive for improving meat quality. The pig feed additive consists of sprouted bean flour, fermentation culture and glycine betaine according to a mass ratio of 1:(0.5-1):(0.2-0.5). The pig feed additive for improving meat quality disclosed by the invention is used for preparing pig feed, the commodity lean meat percentage can be improved, the meat quality is improved, the palatability of the feed is improved, and ingestion and pig growth are promoted.
Description
(1) technical field
The present invention relates to a kind of feed addictive, particularly a kind of safe, efficient, pig's feed additive of improving meat and application.
(2) background technology
Along with the raising of people's living standard, meat quality is more and more subject to the attention of consumers in general.Consumer likes lean meat percentage high, the pork that metabolism of lipid and cholesterol content is low, requires again that its color and luster is good, tenderness is high, succulence, local flavor delicious, unsaturated fatty acid content is suitable simultaneously.And the factor affecting meat quality is a lot, comprise heredity, environment, nutrition and feeding and management etc.
Wherein raising raising and Nutrition Management level are the important channels of improving meat:
1, raise competence directly affects the speed of growth of livestock and poultry and the ratio of body internal protein and fat, thus affects meat.As to 20 ~ 80kg pig, free choice feeding, the speed of growth improves 20%, and in muscle, fat content improves, and meat quality improves, but lean meat percentage declines.
2, energy level improves and can increase body fat content, thus may improve meat tenderness and local flavor, but can reduce lean meat percentage equally.
3, High protein diet can improve pig lean meat percentage, reduce level of intramuscular fat, and meat tenderness declines; Low-protein level can improve meat quality, improves meat tenderness, and its reason may be that the rising of fat content in muscle and Low-protein diet impel body internal protein to have enough to meet the need to accelerate, reduce collagen quantity and crosslinking degree structure.
4, mineral element and vitamin diet add magnesium can alleviate pig stress, improve muscle endpoint pH, increase Coefficient shrinkage, reduce PSE incidence, improve meat quality.Add organic-magnesium, Organic Chromium etc. and can improve production performance, lean meat percentage and yellowish pink.In pig diet, add Organic Selenium significantly to reduce pork and drip juice loss, improve the tenderness of meat and total acceptable.The level improving zinc and manganese in diet also contributes to the generation preventing PSE pork.Sodium bicarbonate, as the electrolyte regulating blood and muscle acid-base balance, can improve muscle pH value and have alleviation stress, improves meat.Study in vitamin more and to meat be significantly improved effect be vitamin E.Vitamin E, on the one hand as biomembranous primary anti-oxidant, can maintain the integrality of cell membrane; On the other hand, vitamin E effectively can suppress the formation of ferrihemoglobin in fresh pork, strengthens the stability of oxyhemoglobin, thus extends the fresh meat desirable yellowish pink holding time.VC can make the aqueous phase in body play antioxidation, has resisting stress, slows down effect that pig butchers rear pH decrease speed, improve the meat of pig.Increase thiamine ration master in the fattening later stage to react if it were not in order to catalytic decarboxylation, but strengthen thiamine flavour precursors effect in meat.
5, natural plant extracts is to the value improving meat and local flavor
Natural plant extracts is improved effect to meat, but different natural plants effects differs, and be exactly same natural plants because the place of production, harvest time, extraction process are different, effect is also different.
Improving meat is a comprehensive problem, only has system and considers correlative factor all sidedly, just can improve constantly the lean meat percentage of animal, improve carcass quality.
The present invention uses the principle of animal nutrition and modern biochemistry, a series of research has been carried out on the principal element affecting meat quality, have studied fermentation culture medium, germination bean powder and betaine to the impact of meat quality and mechanism, through a large amount of feeding experiments, slaughter experiment and laboratory testing analysis, repeatedly screening and optimization, have developed a kind of speed of growth and the lean meat percentage that can improve pig, a kind of feed addictive improving meat of meat can be improved again.
(3) summary of the invention
The invention provides a kind of pig's feed additive improving meat, described pig's feed additive is made up of fermentation culture medium, germination bean powder and betaine.Fermentation culture medium is rich in yeast iron, yeast magnesium, Active Regulation peptide, and germination bean powder is rich in daizeol.The pig's feed additive that the present invention improves meat can improve the speed of growth and the lean meat percentage of pig, can improve meat again.
The technical solution used in the present invention is:
Improve a pig's feed additive for meat, described pig's feed additive is made up of with mass ratio 1:0.5 ~ 1:0.2 ~ 0.5 germination bean powder, fermentation culture medium and betaine;
Wherein, described germination bean powder prepares as follows: soybean and mung bean are mixed 1:0.5 ~ 1.5 in mass ratio, soak, the development stage is entered after immersion terminates, when growing the tender shoots of 2 ~ 4mm, the soybean and mung bean that contain tender shoots are dried, pulverize, the germination bean powder described in acquisition;
