Abstract
A method for improving the marble pattern class of beef features that the feed of beef cattle, whose contents of VA and carrotene are lower than the standard (2200 IU/kg) is applied to the beef cattle for more than 90 days to increase the content of intramuscular fat by 90.6-280.3%, so improving the marble pattern by one class.
Description
One technical field
The present invention relates to increases intramuscular fat content in the beef cattle beef by changing the content of vitamin A and carrotene in the feed, improves beef marbling grade, belongs to the technical field of nutrition regulation beef quality.
Two background technologies
Beef high protein, low fat meet the requirement that people pursue nutrition, health care, and be very high at the western developed country consumption figure.Raising in China along with people's living standard, beef particularly top grade beef consumption figure present the impetus of quick growth always, but top grade beef is because the production cycle is long, production cost and specification requirement height, serious always dependence on import.
It is relevant with Animal lipid metabolism to have reported vitamin A abroad very early.Its acceptor of one of the member of vitamin A family retinoic acid structurally belongs to same super family with steroid hormone receptor and Thyroid Hormone Receptors, and steroid hormone and thyroid hormone and fat metabolism are closely related.Cell in vitro is cultivated and is shown that vitamin A can change and the differentiation and the maturation of beef fat cell.In Japan the investigation with Niu Jinhang is shown that also the concentration of vitamin A in the blood and the marbling grade of beef are remarkable negative correlation.Because the vitamin A utilization rate of adding in the daily ration is subjected to the influence of carotene carotene content in the daily ration very big,, can't determine the amount of the actual obtainable vitamin A of beef cattle if do not consider the content of carrotene in the feed at all.Also accurately do not study vitamin A to other index influence report of beef marbling grade, intramuscular fat content and beef both at home and abroad, yet do not improve the beef intramuscular fat content, improve marbling grade and do not influence the patent of beef cattle health both at home and abroad by vitamin A in the regulation feedstuff and carotene carotene content by feed regulation and control vitamin A and carotene carotene content.
The present invention is directed to above technology to improve intramuscular fat content in the beef, to improve marbling grade and safeguard that beef cattle health is target, a kind of rational feed modulator approach is provided, as reducing production costs, improve beef marbling grade, the key technology of production top grade beef.Adopt the highest longissimus dorsi muscle intramuscular fat content 90.6% that improves of this method, marbling improves one more than the grade, improves gluteus medius intramuscular fat content 280.3%.
Three summary of the invention
A kind of method of improving beef marbling grade, it is characterized in that in beef ox fattening feed, using and be lower than the vitamin A of beef cattle trophic level recommended amounts (2200IU/ kilogram of feed dry) and the content of carrotene, feed more than 90 days, can significantly increase the content of intramuscular fat in the muscle, improving the marbling grade in beef 12-13 intercostal longissimus dorsi muscle cross section, is that the ratio of fatty percentage of liveweight in waterpower, beef nutritional labeling, the pelvic cavity has no significant effect to weightening finish, feedstuff-meat ratio, beef color and luster, beef oxidation resistance, the beef of beef cattle.Adopt this experimental basis daily ration (seeing Table 1), change the vitamin A addition, the test of fattening with 32 12 monthly ages and 16 24 monthly age limousin cows and Luxi Yellow cattle first-filial generation shows, the highest longissimus dorsi muscle intramuscular fat content 90.6% that improves, marbling improves one more than the grade, improves gluteus medius intramuscular fat content 280.3%.

1 technical problem to be solved by this invention
Top grade beef is long owing to the production cycle, production cost height, the serious always dependence on import of China.Therefore, seek a kind of rational nourishing regulate and control technique and method, reduce the top grade beef production cost, shorten the production cycle, extremely important.Existing investigation shows that the content of vitamin A in the beef cattle blood and beef marbling grade are remarkable negative correlation, but cross low vitamin A and can have a strong impact on beef cattle health, vitamin A is the vitamin that need add in cattle feed of generally acknowledging in the world at present, the addition that China and U.S.'s beef cattle trophic level are recommended is every kilogram of feed dry 2200 international units, the external trend that also has addition continuation raising.Simultaneously because the beef cattle liver has the ability of very strong storage vitamin A, therefore control vitamin A addition suitable in the feed, make the blood vitamin A content be controlled at proper level, both guaranteed beef cattle health, it is extremely important to improve beef marbling grade again.
2 technical schemes that address the above problem
For addressing the above problem, key is a suitable vitamins A addition in the control daily ration.By reducing the addition of vitamin A in the cattle feed significantly, control the content of carrotene in the feed simultaneously, make vitamin A in the feed can in the long time, guarantee the health of beef cattle, can increase substantially the content of intramuscular fat again, improve marbling grade.
The technical program is very simple and practical, main method is at first to determine the kind of kind, particularly roughage of the feedstuff of beef cattle, if roughage is adopted high quality forage, adopt the method for exposure in sunshine to make hay, in beef ox fattening feed, do not add or add on a small quantity vitamin A; If roughage is forage grasses inferior such as corn stalk, Wheat Straw, then the content with the vitamin A in the cattle feed additive is reduced to below the trophic level recommended amounts (2200IU/ kilogram of feed dry); The quantity control that vitamin A adds in other roughage feed also is being controlled at below the trophic level recommended amounts.Avoid using fresh high quality forage as far as possible.If carotene carotene content in the strict limiting feed of feed period does not add vitamin A simultaneously, the time is advisable to be no more than 180 days.
3 advantage of the present invention and beneficial effects
Improve the intramuscular fat content in the beef as far as possible under the prerequisite that does not influence the healthy and little amplitude increase of beef cattle production cost, improve marbling grade, this is the key of production top grade beef.Advantage of the present invention is simple, practical, can also reduce production costs, and does not influence the health of beef cattle simultaneously.Adopt technical thought of the present invention to compare with normal diet, the highest longissimus dorsi muscle (commercial west by name the is cold) intramuscular fat content 90.6% that improves, marbling improves one more than the grade, improves gluteus medius intramuscular fat content 280.3%.Other production performance and beef quality index to beef cattle do not have harmful effect simultaneously.
The present invention improves the marbling grade aspect and obtains outstanding effect, and can reduce feed cost improving the beef intramuscular fat content, and method is simple and practical, has broad application prospects in top grade beef is produced.
