Description
본 발명은 사료 내 데옥시니발레놀의 농도를 이용한 양돈의 사양 상태를 진단하는 방법에 관한 것이다.The present invention relates to a method for diagnosing the feeding condition of pigs using the concentration of deoxynivalenol in feed.
최근 축산업의 추세에 따라 양돈 농장도 집단화, 대규모화되어 가고 있으며, 이에 따라 과학적이고 효율적인 사양관리의 필요성이 더욱 대두되고 있다. 실제로 양돈 농장의 주요한 생산성 지표인 MSY(Marketted-pigs per Sow per Year, 모돈 두당 연간 출하두수)를 양돈 선진국과 비교하면 60~80% 수준에 머무르고 있으며, 국내 농가의 상·하위간 격차도 크게 벌어지고 있다. 이에 따라, 과거 50년에 걸쳐, 가축 영양 제공에 대한 접근이 변화되었다. 대부분의 동물 사료는 이를 공급받는 동물을 연명시키기 위한 영양소의 적어도 최소 요구량을 공급하는 것을 주목적으로 하고 있다. 영양소의 수준에 대해 사료를 분석하고 사료가 의도된 동물의 에너지 및 영양소 요건을 충족시키는 경우를 결정하는 필요성이 존재한다. 동물 사료 내의 영양소는 동물의 위장관 내에서 사료의 소화(digestion)에 의해 동물에게 이용 가능하게 된다. 소화되는 영양소는 흡수되고 에너지, 성장, 및 발생을 위해 동물에 의해 사용된다. 소화되지 않는 영양소는 대부분 동물의 장관을 통과하여 사료의 영양소 이용 수준을 감소시킨다. 시험관내 또는 생체내 소화 모델을 사용하고 소화된 사료 내에 잔류하는 영양소를 습식 화학 분석 방법에 의해 분석함으로써 동물 사료의 소화율을 평가할 수 있다. 이와 같은 노력에도 불구하고, 고품질의 양돈 생산을 위한 사양 상태의 개선이 어려운 이유는 양돈의 등급 판정이 도축 후에 이루어진다는 점에서 찾아볼 수 있다. 따라서, 사양 중에 양돈의 상태를 예측하고 그 원인을 찾아 양돈의 상태를 향상시키는 것이 중요하다.In accordance with the recent trend in the livestock industry, pig farms are also becoming collectivized and large-scaled, and accordingly, the need for scientific and efficient breeding management is emerging. In fact, MSY (Marketted-pigs per Sow per Year), a major productivity indicator of pig farms, compared to pig farming developed countries, remains at 60-80%, and the gap between the upper and lower ranks of domestic farms has widened significantly. are losing Accordingly, over the past 50 years, approaches to providing livestock nutrition have changed. Most animal feeds have the primary purpose of supplying at least the minimum requirement of nutrients to sustain the animal receiving them. There is a need to analyze feed for levels of nutrients and determine if the feed meets the energy and nutrient requirements of the animal for which it is intended. Nutrients in animal feed are made available to the animal by digestion of the feed within the animal's gastrointestinal tract. Nutrients that are digested are absorbed and used by animals for energy, growth, and development. Most undigested nutrients pass through the animal's intestinal tract, reducing nutrient availability in the feed. Digestibility of animal feed can be assessed using in vitro or in vivo digestion models and analyzing residual nutrients in the digested feed by wet chemistry methods. Despite such efforts, the reason why it is difficult to improve the specifications for high-quality pig production can be found in the fact that the grade of pigs is determined after slaughtering. Therefore, it is important to predict the condition of pigs during breeding and find the cause to improve the condition of pigs.
한편, 데옥시니발레놀(Deoxynivalenol, DON)은 트리코세신(trichothecene) 그룹에 속하는 곰팡이독소로, 푸사리움(Fusarium) 속의 곰팡이의 2차 대사물질이며, 농작물 특히 밀, 보리, 옥수수 같은 곡류에서 발생한다. 데옥시니발레놀의 오염은 돼지에게 구토를 유발할 수 있어, 종종 구토독소(vomitoxin)라고 불리기도 한다. DON에 의한 중독증은 오염된 농산물 및 가공식품을 직접 섭취함으로써 1차적으로 발생하고, 오염된 농산물이 함유된 사료를 먹은 가축으로부터 생산된 축산물을 2차적으로 사람이 섭취한 경우에도 각종 건강장해 (간장 장애, 신경장애, 신장 장애, 면역기능 저하 등)가 발생할 수 있다. DON은 면역계, 생식기계에 특이적으로 영향을 미치는 물질로서 림프조직의 세포괴사, 위축을 유발하고 리보좀(ribosome)과 결합하여 활발히 분열하고 있는 골수, 비장, 흉선 및 림프세포 등 면역계 장기의 단백질 합성을 저해하여 면역기능을 저하시킨다. 아울러 DON은 구토독소로서 소화기능도 현저히 저하시키고 심한 경우 장 출혈까지 유발한다. 가축에서는 특히 돼지가 민감하며 사료섭취량감소, 구토, 증체량 감소, 면역기능 저하 등을 유발하여 체중증가 감소를 유발하고 성장 지연을 일으켜 생산성 저하를 초래한다.On the other hand, Deoxynivalenol (DON) is a mycotoxin belonging to the trichothecene group. It is a secondary metabolite of fungi of the genus Fusarium, and occurs in crops, especially grains such as wheat, barley and corn. do. Contamination with deoxynivalenol can cause vomiting in pigs, so it is often referred to as vomitoxin. Toxicosis caused by DON is primarily caused by direct consumption of contaminated agricultural products and processed foods, and various health disorders (soybean disorders, neurological disorders, renal disorders, reduced immune function, etc.) may occur. DON is a substance that specifically affects the immune system and reproductive system. It induces cell necrosis and atrophy of lymphoid tissue, and binds to ribosome to inhibit protein synthesis in organs of the immune system, such as actively dividing bone marrow, spleen, thymus and lymph cells. Inhibits and lowers the immune function. In addition, DON is an emetic toxin, which significantly reduces digestive function and, in severe cases, even induces intestinal bleeding. In livestock, pigs are particularly sensitive, and it causes a decrease in feed intake, vomiting, a decrease in weight gain, and a decrease in immune function, thereby causing a decrease in weight gain and a delay in growth, resulting in a decrease in productivity.

하기의 실시예를 통하여 본 발명을 보다 상세하게 설명한다. 그러나 하기 실시예는 본 발명의 내용을 구체화하기 위한 것일 뿐 이에 의해 본 발명이 한정되는 것은 아니다. The present invention will be described in more detail through the following examples. However, the following examples are only for specifying the content of the present invention, and the present invention is not limited thereto.
실시예 1. 기존 방정식의 정확도 검증Example 1. Accuracy Verification of Existing Equations
양돈 사료내 데옥시니발레놀(DON) 농도에 따른 돼지의 사료섭취량 변화량과 체중 증가의 변화량에 대한 정보를 기록한 문헌들을 수집하고, 이로부터 총 59개의 데이터를 수집하고, 이를 기존 방정식 (Mok et al., 2013)의 정확도의 검증에 사용하였다. 기존 방정식 검증은 SAS (SAS Inst. Inc., Cary, NC, USA)의 REG procedure를 이용하여 수행되었다.Literatures that recorded information on the change in feed intake and weight gain of pigs according to the concentration of deoxynivalenol (DON) in pig feed were collected, and a total of 59 data were collected from them, and the existing equation (Mok et al. al., 2013) was used to verify the accuracy. Verification of the existing equations was performed using the REG procedure of SAS (SAS Inst. Inc., Cary, NC, USA).
배합 사료내 데옥시니발레놀(DON) 농도에 따른 체중증가 변화량에 관한 이전 방정식의 검증 결과, 선형 편향(linear bias)을 나타내는 기울기 (-0.27±0.09, P < 0.01)가 통계학적으로 0과 다른 것으로 나타났다 (도 1). 또한, 배합 사료내 데옥시니발레놀(DON) 농도에 따른 사료섭취량 변화량에 관한 이전 방정식의 검증 결과, 선형 편향을 나타내는 기울기 (-0.61±0.07, P < 0.01)와 평균 편향(mean bias)을 나타내는 절편 (-7.75±1.19, P < 0.01)은 통계학적으로 0과 다른 것으로 나타났다 (도 2). 따라서, 기존의 두 방정식의 정확도가 유의미하게 낮은 것을 확인하였다. As a result of verification of the previous equation on the change in weight gain according to the concentration of deoxynivalenol (DON) in the formulated diet, the slope representing the linear bias (-0.27±0.09, P < 0.01) was statistically 0 and 0.09. found to be different (Fig. 1). In addition, as a result of verifying the previous equation regarding the change in feed intake according to the concentration of deoxynivalenol (DON) in the formulated feed, the slope (-0.61±0.07, P < 0.01) and the mean bias representing the linear bias were found. The indicated intercept (−7.75±1.19, P < 0.01) was found to be statistically different from zero (FIG. 2). Therefore, it was confirmed that the accuracy of the two existing equations was significantly low.
실시예 2. 양돈 사료 내 데옥시니발레놀의 농도에 따른 돼지의 사양 성적 분석 Example 2. Analysis of pig performance according to the concentration of deoxynivalenol in pig feed
상기 실시예 1에서 확인한 바와 같이, 기존의 추정방정식은 새로운 데이터를 잘 반영하지 못하였으므로, 정확한 추정 방정식을 새로 도출하기 위해, 양돈 사료 내 데옥시니발레놀의 농도에 따른 돼지의 사양 성적을 분석하였다. 구체적으로, 기존의 문헌들로부터 수집한 상기 59개의 데이터와 실험 데이터를 포함한 총 156개의 데이터를 이용하여 SAS의 CORR procedure를 이용하여 배합 사료내 데옥시니발레놀 (DON) 농도 (0 내지 14.6 mg/kg), 사료섭취량 변화량, 체중증가 변화량, 개시체중, 평균체중과 실험기간 변수들의 상관관계를 결정하고 (통계적 유의성은 P < 0.05일 때로 설정), SAS (SAS Inst. Inc., Cary, NC, USA)의 REG procedure를 이용하여, 배합 사료내 데옥시니발레놀(DON) 농도에 따른 체중증가 변화량을 예측하는 방정식 및 배합 사료내 데옥시니발레놀(DON) 농도에 따른 사료섭취량 변화량을 예측하는 방정식을 도출하였다. As confirmed in Example 1, the existing estimation equation did not reflect the new data well. Therefore, in order to derive a new accurate estimation equation, pig breeding performance was analyzed according to the concentration of deoxynivalenol in pig feed. did Specifically, using a total of 156 data including the above 59 data and experimental data collected from existing literature, the CORR procedure of SAS was used to determine the concentration of deoxynivalenol (DON) in formulated feed (0 to 14.6 mg). /kg), determine the correlation between feed intake change, weight gain change, initial weight, average weight, and experimental period variables (statistical significance is set when P < 0.05), SAS (SAS Inst. Inc., Cary, NC) , USA) using the REG procedure, the equation for predicting the change in weight gain according to the concentration of deoxynivalenol (DON) in the formulated feed and the change in feed intake according to the concentration of deoxynivalenol (DON) in the formulated feed A predictive equation was derived.
(BW: body weight; *P < 0.05, **P < 0.01.)(BW: body weight; * P < 0.05, ** P < 0.01.)
그 결과, 배합 사료내 데옥시니발레놀(DON) 농도는 돼지의 체중증가 변화량 (ΔWG, r = -0.79; P < 0.01) 및 사료섭취량 변화량 (ΔFI, r = -0.71, P < 0.01)과 음의 상관관계를 나타냈다 (표 1). As a result, the concentration of deoxynivalenol (DON) in the formulated feed was significantly different from the change in pig weight gain (ΔWG, r = -0.79; P < 0.01) and feed intake (ΔFI, r = -0.71, P < 0.01). showed a negative correlation (Table 1).

상기 실시예 2의 분석 결과를 기반으로, 독립변수는 배합 사료내 데옥시니발레놀(DON) 농도로 설정하고 종속변수는 돼지의 체중증가 변화량과 사료섭취량 변화량으로 설정하여 하기의 2개의 회귀 추정방정식 (수학식 1 및 2)을 제작하였다 (표 2). 추정 회귀식에서 데옥시니발레놀 (DON) 농도의 범위는 0 내지 14.6 mg/kg이었다.Based on the analysis results of Example 2, the independent variable was set to the concentration of deoxynivalenol (DON) in the formulated feed, and the dependent variable was set to the change in weight gain and feed intake of pigs, and the following two regression estimations were made Equations (Equations 1 and 2) were prepared (Table 2). The range of deoxynivalenol (DON) concentrations in the estimated regression equation was 0 to 14.6 mg/kg.
(1Y-intercept was forced to zero; ΔWG: weight gain changes (%); ΔFI: feed intake changes (%); n = 156)( 1 Y-intercept was forced to zero; ΔWG: weight gain changes (%); ΔFI: feed intake changes (%); n = 156)
*r2 = 0.77 및 P < 0.01*r 2 = 0.77 and P < 0.01
*r2 = 0.68 및 P < 0.01*r 2 = 0.68 and P < 0.01
