Description

Functional feed composition for poultry containing ginseng extract as an active ingredient and a method for producing the same

The present invention relates to a functional feed composition for poultry comprising an extract of sophora koreensis as an active ingredient and a method for preparing the same.

Food consumption in Korea has shifted to a qualitative growth stage since the 1980s due to an increase in income level and increased interest in health. Although the quality of food itself is important, as the population is concentrated in cities, preference for food with high storability and simplification of food consumption is increasing. In addition, the consumption of grain-centered consumption has shifted to meat-centered consumption, and the consumption of meat is continuously increasing. In particular, chicken has continued to grow so that the actual slaughter count has increased from about 400 million per year in 2000 to 1 billion by 2020. are doing As the consumption of broilers increases, interest in native chickens is also increasing. Compared to broilers, native chickens have a lower fat content and are lighter, and their meat is firmer and contains a large amount of amino acids and nucleic acids. have. However, due to the longer breeding period and higher price than broilers, consumers cannot easily access them. Therefore, there is a need for a method to shorten the breeding period or increase the weight gain in breeding native chickens.

In order to increase the supply, it is most effective to increase the number of breeding per unit area, but in the case of high-density breeding, it becomes a problem due to social stress due to competition for feed and drinking water. It is known that such stress causes a decrease in skeletal muscle development and an increase in fat accumulation along with a decrease in the breeding performance of chickens. In addition, oxidative stress was induced by the poor breeding environment, causing problems such as destroying the structure and function of proteins and fat cells. Research on the development of antioxidants as substances that can control free radicals is being actively conducted. Vitamin E or synthetic antioxidants are mainly added as antioxidants to relieve oxidative stress, but vitamin E has limited use in economic terms, and the safety of synthetic antioxidants has been raised. Due to these safety concerns, studies are underway to use natural plants as antioxidants. Most of the natural plant-derived feed additives have antioxidant functions, and Jamroz et al. (2005) reported that the use of plants for antioxidant activity as a feed additive for poultry increases feed intake and immunity. There is also a study report that the addition of grape seed extract as an antioxidant to chicken prevented the formation of lipid peroxide and discoloration of the meat. In addition, when wormwood powder was added to broiler feed, effects such as a decrease in lipid peroxide content and a significant increase in blood antioxidant activity were found, but the mechanism was not clearly elucidated.

On the other hand, Sophora koreensis is a deciduous shrub of the family Rosaceae, a dicotyledonous plant, classified as a Korean endemic plant, and distributed in Yanggu and Inje, Gangwon-do, and South Pyongan Province and South Hamgyong Province in the northern region. Ginseng is known to contain alkaloids and flavonoids with excellent antibacterial and antioxidant effects. It also contains scopoletin, a powerful antioxidant, and scopoletin, a coumarin-based substance, is the main component of plant antioxidants such as noni and wormwood. However, ginseng was designated as an endangered wild plant and animal class II and protected, and although it was released in 2012, the number of individuals was very small and the cultivation method was not developed. Therefore, in this study, carcass characteristics, blood characteristics, meat quality and antioxidant activity of native chickens were investigated when ginseng was added to the feed.

That is, the present invention relates to a functional feed composition for poultry comprising an extract of sophora koreensis as an active ingredient and a method for preparing the same. It was confirmed that the quality of chicken meat was also improved compared to that fed with general feed. That is, based on these results, it will be able to be used as a functional feed composition for poultry containing the ginseng extract as an active ingredient.

Hereinafter, the present invention will be described in more detail using examples. These examples are only for illustrating the present invention in more detail, and it will be apparent to those of ordinary skill in the art that the scope of the present invention is not limited thereto.

Preparation Example 1. ginseng ( sophora koreensis ) Preparation of extract

After adding 10 times 70% ethanol to the above-ground parts (leaf and stem) of ginseng, 10 times 70% ethanol was added, extracted by immersion at room temperature for 24 hours, filtered using filter paper (Watman No. The solvent was removed. The concentrated sample was dried with a freeze dryer to form a powder and added to the feed.

Preparation Example 2. Test design, test animals and breeding management

This study was conducted with the approval of the Institutional Animal care and use committee, Kangwon National University, Korea. In order to examine the effect according to the level of ginseng added in the feed (0, 10, 20, 30ppm), 4 treatments, 6 repetitions, 13 numbers per repetition, a total of 312 native chickens (male, 1914 ±1.7g, 49 days of age) were disclosed. Thus, the specification experiment was performed for a total of 35 days (Table 1). The test feed was in the form of powder, and the nutrient level was formulated to meet or exceed the nutrient requirements suggested in the Korean specification standard (Table 2).

Except for the ginseng used in this test, no other additives or drugs were used. The test food was fed ad libitum, and water was freely drinkable through the nipple. Lighting was performed intermittently (1L:2D) during the test period, and the illuminance was adjusted to 10~15lux. During the test period, the average temperature in the house was maintained at 24°C, and the average humidity was maintained at about 70%. Management of other specifications was carried out according to the practice of this laboratory.

Experimental Example 1. Conductor Characteristics

At 70 days of age, 6 animals per treatment were randomly selected, slaughtered through cervical dislocation, exsanguinated, feathers and legs were removed, and carcass characteristics and relative organ weights were investigated. The carcass percentage was calculated by dividing the carcass from which the intestines were removed by the live weight and converted into a percentage.

Table 2 shows the effects of the addition of ginseng by level in the feed for native chickens on carcass characteristics. In case of carcass performance, no significant difference was found according to the addition of ginseng ( p< 0.05). However, intra-abdominal fat was significantly decreased according to the level of ginseng addition ( p >0.05), and the effect was highest in the treatment group added with 20 ppm. In the case of relative organ weight, the addition of ginseng by level increased the relative weights of the spleen, F sac, and thyroid gland ( p <0.05), and there was a significant difference in the ratio of spleen/F sac ( p <0.05). However, it was found that the addition of ginseng in native chicken feed did not affect the liver weight ( p <0.05).

The spleen and F sac are the main immune-related organs of broilers and are known to improve immune function as their weight increases. The ratio of spleen/F cyst is an indicator of immunosuppression in poultry, and if the spleen is larger, respiratory infections, etc. easily appear as an immunosuppressed state. The thyroid gland is an organ that regulates hormone metabolism in the body by secreting thyroid hormone. Selye et al. (1951) reported that the weight of the thyroid gland, spleen, and F sac decreased when livestock was given a strong and prolonged stressor. In this experiment, the addition of ginseng increased the weight of the spleen and F sac, which is thought to have a positive effect on strengthening the immunity of native chickens.

Experimental Example 3. Meat quality analysis

3-1. pH

The pH was measured after adding 90 ml of distilled water to 10 g of leg meat according to the method of Kim et al. (2018). All samples were homogenized for 30 seconds at 7,000 rpm with a homogenizer (Bihon seiki, Ace, Japan), and then measured with a pH meter (Orion 230A, Thermo Fisher Scientific, Inc., Waltham, MA, USA).

3-2. Water holding capacity

According to the method of Jang et al. (2011), about 0.5 g of leg meat with fascia removed was measured in a test tube and heated in a constant temperature water bath at 80° C. for 20 minutes. After heating, it was allowed to cool at room temperature for 10 minutes, centrifuged at 2,000 × g for 20 minutes, and then the weight of the sample was measured. The water holding capacity was calculated using Equation 1 below.

[Equation 1]

Water holding capacity (%) = [(total moisture - free moisture)/total moisture] × 100

Free moisture = [(weight before centrifugation - weight after centrifugation)/(sample × fat coefficient)] × 100

Fat coefficient = 1 - (fat content)/100

3-3. Cooking loss

According to the method of Kim et al. (2017), about 0.5 g of leg meat with fascia removed was weighed in a test tube and heated in a constant temperature water bath at 80° C. for 45 minutes. The heating loss value was calculated as a percentage of the weight difference before *?* after heating (Equation 2).

[Equation 2]

Loss on heating (%) = (weight before heating - weight after heating)/weight before heating × 100

3-4. six colors

The color of the breast meat was determined by using a Minolta Chromameter CR-300 (Minolta Camera Co., Ltd., Osaka, Japan) to determine the L ^* value indicating the lightness, the a ^* value indicating the redness, and the yellowness (Yellowness) b ^* value was measured by repeating each three times. For standardization of the Minolta chroma meter, a standard color plate (Y = 92.8, x = 0.3134, y = 0.3193) was used.

3-5. Experiment result

Table 4, Figs. 1 and 2 show the effects of the addition of ginseng by level in native chicken feed on the color of breast meat and meat quality of leg meat. There was no significant difference in the color change of breast meat according to the addition of ginseng ( p <0.05). However, in the case of changes in the meat quality of leg meat according to the addition of ginseng, water holding capacity, heating loss, shearing force and pH were improved according to the addition of ginseng ( p <0.05).

Water holding capacity is the ability to retain moisture from external stimuli (Trout, 1988), and it has been reported that the lower the pH, the lower the water holding capacity and increase the loss on heating (Northcutt et al., 1994; Palansk and Nosal, 1991). consistent with the results.

Experimental Example 4. Investigation of antioxidant activity of serum and leg meat

Malondialdehyde (MDA), Superoxide dismutase (SOD), Catalase (CAT), and Total antioxidant (TA) were investigated to determine the antioxidant activity of serum and leg meat. First, about 5 g of leg meat from which the fascia was removed was used for analysis after homogenization with 15 mL of PBS. MDA measurement in serum and homogenized leg meat was performed using the method of Buege and Aust (1978). 50 μL of 7.2% BHA was added to 1 mL of homogenized leg meat and serum, and after stopping the oxidation reaction, 2 mL of 20 mM 2-thiobarbituric acid (15% trichloroacetic acid) reagent was added, followed by heating at 85° C. in a constant temperature water bath for 15 minutes. After heating and standing on ice for 10 minutes, centrifugation was performed at 2,000 × g for 10 minutes using a centrifuge. The upper layer of the centrifuged sample was recovered and absorbance was measured at 531 nm to calculate the TBARS value. SOD, CAT, and TA were analyzed using Cayman's kit (SOD: 706002; CAT: 707002; TA: 709001), respectively.

Table 5 shows the results of analysis of antioxidant activity in serum and leg meat added by level of ginseng in native chicken feed. In the case of serum, MDA, SOD and TA were significantly increased with the addition of ginseng ( p >0.05). However, there was no significant difference in CAT (p<0.05). In the case of leg meat, MDA decreased and SOD and TA significantly increased with the addition of ginseng ( p >0.05). In the case of CAT, there was no significant difference, but the addition of ginseng showed a tendency to increase the activity of CAT ( p = 0.078).

As reactive oxygen species react with the cell membrane, lipid peroxidation occurs, and as a result, MDA is produced. This causes damage to cell membranes and tissues, and is a major factor in cell aging and cell destruction. Han et al. (2012) found that MDA in the blood was significantly reduced in the study result of adding mulberry leaves to broilers, and Kim et al. (2014) found that MDA in chicken meat was significantly reduced in an experiment in which yacon by-product powder and mugwort powder were added to broiler feed. In this experiment, MDA was significantly decreased in chickens fed with ginseng extract-added feed. SOD is an antioxidant enzyme that catalyzes the conversion of intracellular reactive oxygen species to hydrogen peroxide. . Hydrogen peroxide generated by SOD is decomposed into harmless water molecules by CAT and is known to protect the living body from harmful oxygen. Kim et al. (2015) showed that SOD-like activity in blood was significantly increased in an experiment in which quercetin, a metabolite of plants, was added to broiler feed, and this experiment also increased SOD-like activity.

Experimental Example 5. ABTS ⁺ scavenging activity

The ABTS ⁺ measurement method is the method of Kim et al. (2013), which utilizes the phenomenon that the absorbance of the cationic radical of ABTS is suppressed by an antioxidant and thus discolors to a characteristic blue-green color. ABTS ⁺ radical scavenging activity was measured by the method of Roberta et al. (2011). 7mM ABTS solution and 2.45mM potassium persulfate solution were reacted at room temperature for 16 hours in a state of blocking light to form ABTS cations. After reacting for minutes, the absorbance value was measured at 750 nm using a microplate reader (Molecular Devices). As for the antioxidant activity, ascorbic acid (Ac), a solvent in which the sample was dissolved, was used as a control, and the radical scavenging ability of the control was expressed as a percentage.

The results of analysis of ABTS ⁺ scavenging ability in serum and leg meat added by level of ginseng in native chicken feed are shown in FIG. 3 . In the case of serum, ABTS ⁺ scavenging ability was significantly increased according to the addition of ginseng ( p <0.05). In the case of leg meat, there was no significant difference when 10 ppm of ginseng was added, but ABTS ⁺ scavenging ability was significantly increased when 20 and 30 ppm was added ( p <0.05).

In the experiment of Cho et al. (2009), when 0.3% or 1.0% of medicinal plant extracts were fed to broilers, the results of this experiment were consistent with the results of increasing ABTS ⁺ scavenging ability in leg meat according to the storage period.

Experimental Example 6. Statistical Analysis

One-way ANOVA was performed for statistical analysis of the data obtained in this study using SAS (2012), and Tukey's multiple test was performed for comparison between means.
