Description

Feed formula for improving meat quality of broiler chickens

Technical Field

The invention relates to a feed formula, in particular to a feed formula for improving the quality of broiler meat.

Background

The final purpose of broiler chicken production and cultivation is to provide chicken food for people, and for cultivation manufacturers, the growth speed of broiler chickens is particularly important, and the faster the growth speed is, the shorter the output cycle is, and the higher the benefit brought to the cultivation manufacturers is. Therefore, in order to improve the growth performance of the broiler chickens, breeders carry out long-term high-strength breeding on the broiler chickens, the period that the weight of broiler chicken breeding stocks reaches the standard and is on the market is greatly shortened, the carcass composition is changed, the yield of breast chicken is increased, the fat deposition of carcasses is reduced, but the meat quality is indirectly influenced, the chicken fiber composition is changed, and the carcass quality is reduced.

With the continuous improvement of the production performance of broilers and the annual increase of the market share of poultry meat, the meat quality problems of meat color, mouthfeel, shearing force and the like are more and more concerned by consumers, people are more and more favored to favor chicken products with bright color and fresh mouthfeel, and are reluctant to purchase chicken with dark color, hard muscle texture, layering, and woody mouthfeel and firewood. How to ensure the chicken quality on the premise of ensuring the growth rate of the broilers becomes a technical problem to be urgently solved by breeding manufacturers. At present, in the prior art of the market, measures such as adding plant extracts and traditional Chinese medicines into the feed are mostly adopted for improvement, the cost is high, and the effect is very little.

Disclosure of Invention

In order to solve the problems in the background art, the invention provides a feed formula for improving the quality of meat of broiler chickens, and the formula has low production cost, can promote the growth of the broiler chickens and improve the quality of the meat.

In order to achieve the purpose, the invention adopts the technical scheme that: a feed formula for improving the quality of broiler meat comprises the following components in percentage by weight: 55 to 60 percent of corn; 25-30% of soybean meal; 3 to 5 percent of flour; 3% -5% of cottonseed protein; 1% -4% of peanut meal; 1-2% of corn protein powder; 1% -4% of soybean oil; 1.5 to 1.8 percent of stone powder; 1 to 1.2 percent of calcium hydrophosphate; 0.15 to 0.2 percent of methionine; 0.08% of threonine; lysine (content 70%) 0.8%; 0.12 percent of trace elements; 0.26% of salt; 0.1% of baking soda; 0.04 percent of broiler chicken compound multivitamins; 0.01 percent of phytase; 0.03 percent of arginine; 0.05% of valine; 0.03 percent of vitamin C phosphate; 0.01 percent of vitamin E.

Compared with the prior art, the invention has the beneficial effects that:

the invention fully considers the balance of amino acid, particularly the balance of arginine and valine, additionally adds vitamin C phosphate and vitamin E, adopts the combination of the four nutritional additives, can effectively promote the growth of broiler chickens, improves the chicken quality, and produces the chicken which has fresh and tender meat color, good texture and good taste, is more beneficial to the health of eaters, is green, safe and healthy, and is deeply loved by the majority of consumers.

Detailed Description

The invention provides a feed formula for improving the quality of broiler meat, which comprises the following components in percentage by weight: 55 to 60 percent of corn; 25-30% of soybean meal; 3 to 5 percent of flour; 3% -5% of cottonseed protein; 1% -4% of peanut meal; 1-2% of corn protein powder; 1% -4% of soybean oil; 1.5 to 1.8 percent of stone powder; 1 to 1.2 percent of calcium hydrophosphate; 0.15 to 0.2 percent of methionine; 0.08% of threonine; lysine (content 70%) 0.8%; 0.12 percent of trace elements; 0.26% of salt; 0.1% of baking soda; 0.04 percent of broiler chicken compound multivitamins; 0.01 percent of phytase; 0.03 percent of arginine; 0.05% of valine; 0.03 percent of vitamin C phosphate; 0.01 percent of vitamin E.

The balance of arginine and valine is fully considered in the formula, and vitamin C phosphate and vitamin E are additionally added, so that the formula has the following main effects:

arginine: arginine has important effects on animal growth and nitrogen balance. Most mammals can synthesize arginine by themselves to meet the requirements of the mammals, however, broiler chickens cannot synthesize arginine by themselves and completely depend on daily ration arginine to meet protein synthesis and other functions. The performance of the broiler chickens is influenced by various factors such as density, cold and heat stress, diseases, vaccination, infection, illumination and the like in the feeding process. For example, shock treatment during slaughter of broiler chickens significantly increases cholesterol and increases oxidative damage to the pectoral muscles, thereby affecting carcass quality. The daily ration supplemented with arginine can directly or indirectly relieve stress of poultry through metabolism. Arginine supplementation can regulate fat deposition through citrate metabolism. First, citric acid, the most major metabolic prerequisite for arginine, helps to reduce the deposition of undesirable fats. High arginine diets increased pectoral muscle rate and muscle fiber diameter.

Valine: belonging to the group of branched chain amino acids which are essential amino acids for maintaining the normal growth of animals, but cannot be synthesized by humans and animals themselves and must be supplied with feed, the main biological actions of valine include: regulating the synthesis and degradation of proteins; oxidation, decomposition and energy supply in certain special physiological periods such as hunger, exercise, lactation and the like; improving the immunity of the organism, and the like; the optimum addition amount and the addition effect of the valine required in the feed are determined in each growth stage of the livestock and the concentration or the level of other nutrient substances under the determined valine level are important.

Vitamin C phosphate ester: vitamin C is required for synthesizing collagen, so that VC is deficient, collagen cannot be normally synthesized, cell connection is obstructed, and VC mainly participates in a plurality of redox reactions of an organism. Participate in the generation of intercellular substance, and have good anti-inflammatory, antiallergic, anti-stress and antidotal effects.

Vitamin E: in the modern high-density culture production process, the poultry has reduced ability to resist external stressors, and once the balance between oxidants and antioxidants of the body is broken, the poultry is easy to cause the growth performance of the poultry caused by oxidative stress, and during the immune response of the poultry, phagocytes of the body can also generate active oxygen to kill pathogenic bacteria, but in this case, the excessive generation of free radicals can also cause the oxidative damage of normal cells of the body, including immune cells. It is therefore important that the body maintains good antioxidant capacity, both during normal metabolism and during the immune response. The vitamin E added into the daily ration of the broiler chicken can play a role in improving the oxidation resistance and the meat quality

In order to obtain better production performance, people can increase the content of unsaturated fatty acid in poultry meat by adjusting the nutrient concentration of a feed formula, but the unsaturated fatty acid can make the meat and meat products easily deteriorate due to fat oxidation, and experiments prove that vitamin E can reduce the lipid oxidation speed, maintain the integrity of cell membranes after slaughter, improve the meat color and reduce the ratio of woody breast.
