Embodiment 1

[0025] Weigh 300g of threonine (98%), 200g of guanidinoacetic acid (30%), 40g of L-carnitine (50%), 30g of chromium picolinate (0.2%), add cornstarch or calcium carbonate to 1000g, fully After uniform mixing, the feed additive premix for improving meat quality is obtained.

[0026] The feed additive premix for improving meat quality was added to the complete feed of fattening pigs with the same week age and similar body weight in Du long three-way hybridization according to the proportion of 0.5%, and its effect on growth performance and meat quality was studied. The research results showed that the feed-to-meat ratio decreased by 9.56%; average daily gain increased by 11.2%; lean meat rate increased by 10.48%; 24-hour muscle drip loss decreased by 17.62%; meat color increased by 13.76%; the pH value of longissimus dorsi muscle, crude protein However, there was no significant difference in fat content; the selenium content in serum, muscle, and liver showed an obvious upward t...

Embodiment 2

[0028] Weigh 500g of threonine (98%), 300g of guanidinoacetic acid (30%), 60g of L-carnitine (50%), 30g of chromium picolinate (0.2%), add cornstarch or calcium carbonate to 1000g, fully After uniform mixing, the feed additive premix for improving meat quality is obtained.

[0029] The feed additive premix for improving meat quality was added to the complete compound feed of broiler chickens at a ratio of 0.5%, and its effect on the quality of broiler chicken was studied. The results of the study showed that the breast muscle rate increased by 12.64%; the flesh color increased by 11.69%; the 24-hour muscle drip loss decreased by 17.62%; the selenium content in the muscle tended to increase, but the difference was not significant. The MDA level in the muscle was significantly reduced.

Embodiment 3

[0031] Weigh 400g of threonine (98%), 250g of guanidinoacetic acid (30%), 50g of L-carnitine (50%), 30g of chromium picolinate (0.2%), add cornstarch or calcium carbonate to 1000g, fully After uniform mixing, the feed additive premix for improving meat quality is obtained. This meat quality improving feed additive premix was added to the complete compound feed of meat ducks at a ratio of 0.05%, and its effect on the quality of broiler meat was studied. Results of the study showed a 13.21% increase in pectoral muscle rate; a 12.05% increase in flesh tone; a 15.38% reduction in 24-hour muscle drip loss; and a significant reduction in muscle shear force of 15.67%.

[0032] In summary, the present invention combines threonine, guanidinoacetic acid, L-carnitine, and chromium picolinate according to scientific compatibility, and fully exerts the effects of reducing fat deposition, increasing lean meat percentage and improving meat quality. Much higher than the effect of a single in...

Abstract

The invention discloses a meat quality improving feed additive premix. The meat quality improving feed additive premix is prepared from, by mass, 20-40% of threonine, 20-40% of guanidinoacetic acid, 4-8% of L-carnitine, 2-4% of chromium picolinate and a carrier. A utilization method of the meat quality improving feed additive premix includes that the premix is added into animal complete feed according to a proportion of 0.25%-0.5%. By scientific compatibility, threonine, guanidinoacetic acid, L-carnitine and chromium picolinate are combined; according to repeated experiments, synergistic effects of the four components in scientific compatibility are verified, joint use of threonine, guanidinoacetic acid, L-carnitine and chromium picolinate is remarkably superior to single use of the four components, and reasonable cost performance is realized.

Description

technical field [0001] The invention relates to a feed additive premix for improving meat quality and a using method thereof. Background technique [0002] With the improvement of people's living standards, consumers have put forward higher requirements for the quality of pork. Pigs from local excellent breeds are highly appreciated for their bright red meat color, strong water strength, rich marbling, fresh and juicy taste, good flavor, and low incidence of PSE (pale-soft-exudative) meat and DFD (dark-firm-dry) meat. Consumer favorite. How to increase the growth rate and lean meat percentage while improving pork quality has become a problem faced and concerned by the majority of animal husbandry and veterinary workers. [0003] Although hybridization improvement, variety selection, nutritional control and other methods have achieved significant results in improving production performance and lean meat percentage, they have also brought about a decline in meat quality, mai...
