Problems solved by technology

Among them, nutrition plays an important role in the regulation of pork quality, but it is relatively high to improve the growth rate and lean meat percentage through the selection and proportion of nutrients, and comprehensively consider factors such as pork quality and feeding costs to obtain a scheme suitable for large-scale application. challenging

preparation example Construction

[0027] A preparation method of the functional feed, comprising the steps of:

[0028] (1) Preparation of matrix feed;

[0029] The protein feed, energy feed, minerals and vitamins used as raw materials are respectively crushed, mixed evenly, and mechanically pressed to form granules;

[0030] Among them, the particle size of the crushed raw materials should be above 40 mesh; uniform mixing means that various raw materials need to be fully stirred when mixing, and the coefficient of variation should not be greater than 7%; the diameter of the particles is 2 to 4 mm, and the length is the diameter of 1.5 to 2 times;

[0031] (2) The addition of additives;

[0032] The feed additive is mixed and prepared in advance, and then uniformly added to the matrix feed; or added to the matrix feed one by one by mass.

[0033] The functional feed is applied to the breeding of three-element hybrid fattening pigs.

Embodiment 1

[0035] A feed additive for improving pork quality, comprising betaine, vitamin E and chromium picoline; the mass ratio between betaine, vitamin E and chromium picoline is 1000: 100 : 0.2.

Embodiment 2

[0037] A feed additive for improving pork quality, comprising betaine, vitamin E and chromium picoline; the mass ratio of betaine, vitamin E and chromium picoline is 1000: 150 : 0.2.

Abstract

The invention discloses a feed additive, functional feed and a preparation method and application thereof. The feed additive comprises betaine, vitamin E and chromium picolinate in a mass ratio of (1250: 100)-(200: 0.2); when the feed additive is added into matrix feed according to a weight proportion of 0.14% and fed to a ternary crossbred finishing pig (about 60kg), the pork quality can be obviously removed; and the matrix feed comprises 65.5% of corn, 19% of soybean meal, 4% of rapeseed meal, 5% of No. 4 meal, 4% of wheat bran, 6% of calcium hydrogen phosphate, 0.5% of stone powder, 0.4% of salt, 0.1% of lysine, 0.25% of composite trace elements and 0.02% of multivitamins. The feed additive can reduce or reassign fat in the body of the pig, prolong the preservation time of fresh meat, reduce animal stress in transit and at a transfer place and increase glycogen storage in muscles, thereby reducing the generation of PSE (pale, soft and exudative) meat and DFD (dry, firm and dark) meat; and the chromium picolinate can increase lean meat rate and improve the carcass quality.

Description

technical field [0001] The invention relates to the field of pork quality nutrition control, in particular, the invention relates to a feed additive for improving pork quality, a functional feed and a preparation method and application thereof. Background technique [0002] In recent decades, through the selection of genetic breeding, the improvement of nutritional level, and the control of environmental conditions, the meat production performance of pigs has been improved, especially the lean meat percentage and growth rate of pigs have been greatly improved. However, the improvement of growth rate and lean meat rate may reduce the muscle quality of pigs, especially the appearance of PSE and DFD meat, which has caused great harm to the vital interests of pig industry, meat food processing industry, wholesale and retail business and consumers Huge loss. Animal nutrition researchers have also increased lean meat percentage and meat quality by adding clenbuterol to feed, and ...
