Problems solved by technology

In addition, under the conditions of modern genetics and feeding management, inferior meat of commercial pigs (such as PSE meat, DFD meat) occurs from time to time, and the meat color, tenderness and moisture retention of pork after slaughter are significantly reduced, which affects the normal sales of pork and seriously reduces production. benefit

Abstract

The invention discloses an ante-mortem feed for improving the carcass composition and the meat quality of fattening pigs as well as a preparation method and application thereof, and belongs to the technical field of feeds. Each kilogram of the feed is prepared from the following components in parts by weight: 640-680 g of corn, 120-150 g of soybean meal, 120-170 g of soybean hull or bran, 2-3 g ofL-lysine hydrochloride, 0.4-0.6 g of L-threonine, 15-25 g of conjugated linoleic acid, 8-12 g of calcium hydrophosphate, 6.4-12 g of mountain flour, 8.5-10 g of table salt, 0.1-0.2 mg of selenium yeast, 0.05-0.1 g of a free radical scavenger, 20-40 mg of vitamin E and 8-15 g of compound vitamin and mineral premix. According to the ante-mortem feed, the subcutaneous fat percentage of the fatteningpigs can be decreased, the lean meat percentage and the intramuscular fat content can be increased, and the meat quality can be improved. The feed is mainly used in the later fattening period (2-4 weeks before slaughtering), and the input-output ratio is high.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to an ante-mortem feed for improving carcass composition and meat quality of finishing pigs, a preparation method and application thereof. Background technique [0002] The carcass composition and meat quality of commercial pigs are mainly affected by factors such as genetics (breed), nutrition and feeding management. The crossbreeding and intensive breeding mode adopted for a long time to reduce the cost of meat production have had a relatively large negative impact on pork quality, so it is necessary to improve the carcass composition and meat quality of lean pigs through nutritional intervention. The quality of meat is mainly reflected in the intramuscular fat content, meat color, tenderness, moisture content, pH value, etc. Among them, the intramuscular fat content is the most critical factor in determining the quality of pork, and its value is often the same as that of...
