Embodiment 1

[0040] Embodiment 1, the meat quality improver provided by the present invention is to the carcass quality of growing and finishing pig and the impact test of meat quality

[0041] Experimental pigs: In the pig breeding farm of Jiangsu Province, the Landrace*Xiaomeishan hybrid piglets (10 males and 10 females) born to Xiaomeishan sows of the disease-free inbred line with similar age and body weight were selected. ± 1 kg) into the 8-day pre-trial period, deworming, castration, immunization, body weight (20 ± 1) kg into the formal test period, a total of 118 days.

[0042] The composition and calculation level of the basic diet: with 60 kg body weight as the boundary, it is divided into No. I feed in the early stage and No. II feed in the later stage. The specific composition is shown in Table 1.

[0043] Feeding management: The test pigs are kept in two adjacent pens in the same fat pig building, and special personnel are in charge. Free feeding, No. I material in the early st...

Embodiment 2

[0068] Embodiment 2, the comparative feeding test of adding the meat quality improver provided by the present invention in the fattening pig ration

[0069] Experimental pigs: select fattening pigs with the same age and similar body weight as the three-way cross between Du and Long.

[0070] Feed: Powdered compound feed was produced according to the fattening composition provided by Xiantao pig farm, and the composition of the experimental diet is shown in Table 6.

[0071] Table 6, Test pig diet composition and nutritional level (%)

[0072]

[0073] Wherein, the concrete composition of 1044 premix is ​​as shown in table 7; The concrete composition (parts by weight) of meat quality improver is as follows: vitamin C: 60 parts, vitamin E: 25 parts, ferrous fumarate: 40 parts, selenous Sodium nitrite: 0.04 parts, betaine: 70 parts, L-carnitine: 12 parts, lysine: 40 parts, methionine: 30 parts, threonine: 30 parts.

Abstract

The invention discloses a meat quality modifier as well as a preparation method and an application thereof. The meat quality modifier provided by the invention comprises the following components: vitamin C, vitamin E, ferrous fumarate, sodium selenite, betaine, L-carnitine and lysine, as well as methionine and threonine. The parts by weight of the components are shown as follows: 30-100 parts of vitamin C, 3-50 parts of vitamin E, 20-60 parts of ferrous fumarate, 0.02-0.1 part of sodium selenite, 30-100 parts of betaine, 3-20 parts of L-carnitine, 18-80 parts of lysine, 10-50 parts of methionine, and 10-50 parts of threonine. The method for preparing the meat quality modifier is implemented by evenly mixing the above components to obtain the meat quality modifier. The addition of the meat quality modifier to pannage can obviously improve lean meat percentage of growing-finishing pigs, improve meat quality and flesh color, and prevent beta exhilarant from harming human beings, thus ensuring good production benefit of farmers and sound development of hog industry.

Description

technical field [0001] The invention relates to a meat quality improver and its preparation method and application. Background technique [0002] With the improvement of people's living standards, the demand for meat products is no longer just an increase in quantity, but more attention is paid to the improvement of quality, requiring meat products to be rich in nutrition, with good taste and sensory properties. However, the stress caused by genetic selection and routine management to improve production performance has reduced the quality of meat products. Meat products contain high unsaturated fatty acids, which are prone to fat oxidation, which accelerates the color loss of meat products and the ability to retain water. Therefore, improving the quality of livestock and poultry meat has become another hot spot in animal nutrition research. The harm done to people by the illegal use of beta-stimulants is well known. [0003] 1. Toxic and side effects of β-agonists and thei...
