Description

Technical Field

[0001] The invention relates to the technical field of pig feed, and specifically relates to a feed formula for improving the color of pig fur. Background Art

[0002] 1. The importance of pig hair color 1. Variety characteristics and quality identification The coat color of a pig is one of the important appearance characteristics of a breed. For purebred pigs, a specific coat color is a direct reflection of the purity of the breed. For example, the Landrace pig, its iconic white coat is a typical feature of the breed. In the process of breeding and selling breeding pigs, the purity of coat color is often a reference factor in measuring the quality of breeding pigs, which helps to maintain the purity of the breed and the inheritance of excellent traits.

[0003] In the live pig trading market, coat color also affects the price and sales of pigs. Consumers and buyers usually have a higher preference for pigs with uniform and beautiful coat color, because this to some extent implies the health status and quality of the pigs.

[0004] 2. Indirect reflection of health status The coat color of a pig can indirectly reflect its health status. Healthy pigs usually have shiny and smooth coats, while dull, rough coats or coats with patches of different colors may be a sign of nutritional deficiency, illness or stress. For example, when pigs lack vitamins or trace elements, their coats may become rough and faded; when they are infected with parasites or diseases, their coat color may change, such as red spots and scabs, which may affect the appearance and market value of the pigs.

[0005] 2. The influence and limitations of traditional feed on pig hair color 1. The role and deficiency of basic nutrients Traditional pig feeds mainly focus on the growth rate and meat quality of pigs, and contain basic nutrients such as carbohydrates, protein, and fat. Protein is the raw material for the synthesis of keratin, the main component of pig hair, and sufficient protein intake is necessary for the growth of pig hair. However, the protein in the basic feed alone may not meet the needs of high-quality growth of pig hair. For example, some inferior protein sources may not provide enough sulfur-containing amino acids (such as cystine and cysteine), which are essential for maintaining the strength and gloss of pig hair.

[0006] Carbohydrates and fats mainly provide energy, but if the energy supply is excessive or unbalanced, it may affect the overall health of the pig, which in turn indirectly affects the coat color. For example, high-energy feed may cause pig obesity, trigger metabolic problems, and reduce the quality of the pig's coat.

[0007] 2. Lack of targeted nutritional elements Conventional feeds often do not adequately consider specific nutrients that have an important impact on pig hair color. Some vitamins and trace elements play a key role in the formation and maintenance of pig hair color, but may be insufficient or lack a reasonable ratio in conventional feeds. For example, vitamin E is a powerful antioxidant that protects pig skin and hair follicle cells from free radical damage and plays an important role in maintaining the brightness of hair color. However, in conventional feeds, the amount of vitamin E added may not be optimized according to the needs of improving pig hair color.

[0008] Trace elements such as zinc, copper, and selenium also have a significant effect on pig hair color. Zinc is involved in the synthesis of multiple enzymes in the body, which play a key role in the metabolism of skin and hair; copper is a component of key enzymes involved in pigment synthesis; and selenium helps maintain cell health through its antioxidant function, thereby affecting hair color. However, the addition of these trace elements in traditional feeds often focuses on meeting basic growth needs rather than specifically improving hair color. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. Improve the color of pig fur through glycine iron In the pig's physiological system, iron is a key component of hemoglobin, myoglobin and a variety of enzymes. Glycine iron improves the synthesis efficiency of hemoglobin, ensures the efficient transport of oxygen, enables hair follicle cells to work normally, and promotes healthy hair growth.

[0019] 2. Improving the color of pig fur by adding sulfur-containing amino acids Methionine is a type of sulfur-containing amino acid. It is one of the essential amino acids for pigs, which means that pigs cannot synthesize it themselves and must ingest it from the outside. In the pig's body, methionine is involved in the synthesis of overall protein. Pig hair is mainly composed of keratin, and the synthesis of keratin depends on an adequate supply of amino acids. Methionine plays an important role in the synthesis of keratin.

[0020] 3. Improve fat utilization through bile acid Bile acids play an extremely important role in the digestive system of pigs, especially in improving fat utilization, which has an indirect effect on the overall health and fur quality of pigs. Fat is one of the important sources of energy in pigs. When fat can be fully utilized, pigs can obtain more sufficient energy to maintain normal physiological functions and growth and development. This includes the healthy development of skin and hair follicles, because sufficient energy supply can ensure the normal metabolism and proliferation of hair follicle cells, which helps the normal growth of hair. In addition, some unsaturated fatty acids have special effects in maintaining the health of skin and hair, such as improving the lipid layer structure of the skin and making the hair smoother and more shiny.

[0025] Comparative experiment 1. Purpose of the experiment To explore the effect of this feed on pig hair color, provide a more scientific basis for feed selection for pig breeding, and understand the potential relationship between feed ingredients and pig hair color changes.

[0026] 2. Experimental Subjects Select 40 Landrace pigs of similar age and weight (age about 2-3 months, weight about 30 - 40 kg), in good health and with normal coat color, ensuring that the initial coat color of the pigs is basically the same.

[0027] 3. Experimental Materials Feed preparation Feed A: Ordinary commercial pig feed is used, and its nutritional composition meets the basic needs of this breed of pigs at this growth stage, including appropriate amounts of protein, carbohydrates, fat, vitamins and minerals.

[0028] Feed B: The formula of Example 2 of the feed for improving pig fur color is adopted.

[0029] Experimental equipment Colorimeter: Used to measure the Lab* value of pig hair color to objectively evaluate hair color changes.

[0030] Pig houses and feeding equipment: Provide suitable feeding environment, including clean drinking water equipment, ventilation system and appropriate temperature control system.

[0031] 4. Experimental Grouping 40 pigs were randomly divided into two groups, each with 20 pigs, respectively marked as group A and group B. The pigs in group A were fed with ordinary commercial pig feed, and the pigs in group B were fed with the formula of Example 2 of the feed for improving pig fur color.

[0032] 5. Experimental steps Preliminary preparation (Day 1) An initial coat color measurement was performed on each pig. The Lab* value of coat color was measured at multiple locations on the pig's body (back, abdomen) using a colorimeter and the data were recorded.

[0033] Place the pigs in their respective pig houses, ensure that the breeding environment is the same, and keep the temperature, humidity, light and other conditions consistent in each group of pig houses.

[0034] Feeding process (Day 2 - 90) Feed the A and B groups of pigs with the corresponding feed at the same time every day, ensuring that the feed amount is based on the pigs' weight and growth stage according to the standard feeding procedures, and provide sufficient and clean drinking water.

[0035] Clean and disinfect the pig house every week to maintain a good sanitary environment.

[0036] Coat color measurement (30th, 60th, 90th day) On the 30th, 60th and 90th days, the color of the pigs' hair was measured again using a colorimeter. The measurement method was the same as the initial measurement, and the changes in the Lab* value of the hair color were recorded. At the same time, the appearance changes of the pigs' hair color were observed, such as whether the glossiness changed, the color became darker or lighter, whether there were stray hairs, etc., and they were recorded in detail.

[0041]

[0042] VII. Experimental Results The L* value (brightness) of pigs in group A was gradually increasing and becoming brighter every 30 days, while the L* value of pigs in group B did not change significantly. The data fluctuations were within the normal range. The data showed that the feed in group A had a significant effect on brightening the hair color of pigs. The a* value (redness and greenness) of the pigs in groups A and B was tested every 30 days and increased or decreased within a small range. For normal Landrace pigs, their coat color basically does not contain red or green components. In actual measurement, the a value may fluctuate slightly due to measurement errors or other factors. This is a change value within the normal range. The data shows that the feeds in groups A and B have no effect on the redness and greenness of pigs. The b* (yellow-blue color) value of Group A pigs tested every 30 days is gradually decreasing, while the b* value of Group B pigs is either rising or falling in a disordered state. The hair of Landrace pigs has some yellowish hue. The data shows that Group A feed has an adjusting and reducing effect on the yellow-blue color.
