Aflatoxin과 비타민D₃의 相互作用을 究明하기 위하여 브로이러 병아리 336 首를 8區로 나누고 aflatoxin B₁을 0 또는 0.5ppm, 비타민D₃를 0, 500, 1,000 또는 1,500IU/Kg 給與하는 3週間의 2×4 要因試驗을 實施하였다. 增體量, 飼料攝取量, 飼料轉換率, 정강이 色相,斃死率 및 脚弱症發生率에 있어서 各區間 有意差를 나타내지 않았다. 乾物, 組蛋白質, 組脂肪, 可溶無室素物 및 組灰分의 利用率에 있어서 各 區間 有意差를 나타내지 않았다. 組織維의 利用率에 있어서 對照區에 比하여 aflatoxin 給與區가 매우 낮은 값을 보였다(P < .01). 그러나 비타민D₃가 添加水準間에는 有意差를 나타내지 않았으며 aflatoxin과 비타민D₃間의 交互作用도 認定되지 않았다. Ca, P 및 Na의 利用率에 있어서 各 區間 有意差를 보이지 않았으나 aflatoxin 給與區의 Ca 利用率이 無給與區보다 약간 높았다. 脫脂乾燥脛骨의 灰分含量은 各 處理間 有意差가 없었으나 Ca含量에 있어서도 aflatoxin 0.5ppm區에서 無給與區보다 더 많았으며(P < .05), 비타민D₃를 더 많이 給與할수록 조금씩 높게 나타났다. Aflatoxin과 비타민D₃가 脛骨內 Ca을 加速的으로 增加시킨다는 것을 보여 주었다(P < .01). 그리고 P의 含量에 있어서도 aflatoxin給與로 增加되었다(P < .05). 그러나 비타민D₃水準間에는 有意差가 없었으나 2要因間의 交互作用도 없었다. Aflatoxin給與는 Na含量에 影響을 주지 않았으나 비타민D₃水準間에는 有意差가 나타나(P < .01) 1,000IU/Kg水準이 가장 높게 나타났다. 2要因間의 交互作用은 認定되지 않았다. 血淸中의 Ca濃度에 있어서 aflatoxin給與區에서 매우 높게 나타났으며(P < .01), 有意性은 없었으나 비타민D₃添加水準이 높아질때 조금씩 增加되는 傾向을 보였다. 2要因間의 交互作用이 認定되었다(P < .05). P의 含量은 各 處理間에 有意差가 없었으며 Alkaline Phosphatase 力價에 있어서 aflatoxin給與區가 높은 값을 보였다(P < .01). 그리고 비타민D₃水準이 높아짐에 따라 조금씩 增加하는 趨勢를 보였으나 有意差는 없었으며 Aflatoxin과 비타민 D₃間에는 交互作用이 없었다. A 2×4 factorial study was carried out to investigate the interaction of aflatoxin and vitamin D₃in broiler chicks. The day-old 336 chicks were allocated to triplicate 8 treatments. The 0 or 0.5ppm of aflatoxin B₁(AFB) and 0, 500, 1,000 or 1,500 IU/Kg of vitamin D₃(VD) were supplemented to the basal diet. There were no significant differences among treatments in respect to the body weight gain, feed intake, feed conversion, shank color, mortality and incidence of weak legs. The utilization efficiencies of dry matter, crude protein, ether extract, N-free extract and crude ash showed also no significant differences among treatments, respectively. The mean utilization efficiency of crude fiber in AFB group was lower than that in normal group(P <.01). However, no significant difference was found among groups fed different levels of VD, and no interaction between AFB and VD was found. The utilization efficiency of Ca in AFB group was somewhat higher than that in normal group without statistical significance, and the similar values were found among groups fed different VD. The utilization efficiencies of P and Na were not significantly different among treatments, respectively. The tibia ash appeared to be similar among treatments fed different levels of AFB and VD. However, the Ca content in tibia of birds fed 0.5ppm of AFB was higher than that of normal chicks (P <.05). The slightly increasing trend was shown in Ca contents when fed increasing level of VD, and the interaction between AFB and VD was recognized(P <.01). The P content of tibia was increased by feeding AFB(P <.05). However, there was no significant difference among groups fed different level of VD and no interaction between AFB and VD in respect to the P content of tibia. Feeding AFB did not affect the Na content in tibia. However, there was a highly significant difference among groups fed different levels of VD(P <.01), the highest values were at 1,000 IU/Kg group, and the interaction between AFB and VD was not significant. The Ca content in serum of birds fed AFB was higher than in control group(P <.01). The Ca of serum increased when fed more VD, although no significance was found among groups, and there was an interaction between AFB and VD(P <.05). The P content of serum showed no significant difference among treatments. The alkaline phosphatase activity in serum of chicks fed AFB was higher than that of control group(P <.01). The enzyme activity increased slightly with increasing level of VD, however, there was no interaction between AFB and VD.

Broiler 사료의 영양밀도 및 Zeolite 수준이 증체 , 영양소 이용율 및 혈액성상에 미치는 영향

장윤환,여영수 ( Y . H . Chiang,Y . S . Yeo ) 한국축산학회 1983 한국축산학회지 Vol.25 No.6

A factorial experiment was carried out to investigate the effect of two nutrition densities and three zeolite levels ( 0, 1.5 and 3.0 percent) on body weight gain, feed efficiency, nutrient utilization, mineral balance, serum characteristics and feed cost of broilers. The day-old Hubbard chicks were$quot; allocated to tripilcate of six treatments. The body weight gain of chicks was not influenced by zeolite level in diets of high nutrition density. However, an increasing body weight performance was recognized when increasing levels of zeolite were supplemented to the diets of low nutrition density, even though no significant difference was found among these treatments. Feed efficiency was improved by the addition of 1.5% zeolite to the ration with high nutrition density. However, similar efficiencies were recorded for chicks fed diets containing different zeolite levels and low nutrition density. The utilization efficiencies of proximate nutrients were highest for chicks receiving no zeolite. Similarly the utilization efficiencies of calcium, phosphorus, potassium and sodium were highest with diets containing no zeolite, whereas for magnesium, manganese and zinc the efficiency of utilization was highest for diets containing zeolite. The calcium contents of serum taken from chicks fed no zeolite were higher than those of treatments containing zeolite. There was no significant difference among phosphorus content of serum from any treatment. The level of alkaline phosphatase in serum from high nutrition density diets was higher than chicks fed low nutrition density diets, while in serum from chicks fed increasing levels of zeolite these levels increased in high nutrition density group, but not significantly. The reverse trend was recognized in low nutrition density treatment, also not significantly. The mean feed cost per Kg body weight gain of chicks fed ration with I.5% zeolite was lowest for treatments from high nutrition density diets and that with 3.0% zeolite was lowest in chicks fed low nutrition density diets. The high nutrition density diet cost more per unit gain of body weight than the low nutrition density diets.

Aflatoxin $B_1$과 Vitamin $D_3$ 결여가 Broiler병아리의 중족골 무기물함량에 미치는 영향

장윤환,여영수 한국가금학회 1990 韓國家禽學會誌 Vol.17 No.4

This study was conducted to investigate the interaction of aflatoxin B$_1$($AFB_1$) and vitamin D$_3$($VD_3$) in broiler chicks. The 336 broiler chicks(Hubbard line) of equally mixed sex were allocated to triplicate 8(2$\times$4 factorial) treatment groups. The 0 or 1ppm of AFB$_1$and 0, 500, 1,000 or 1,500IU/kg of VD$_3$ were supplemented to the basal diet Fourteen broilers of equally mixed sex were allocated to each replica and 24 groups were arranged in a randomized block design After 3 weeks of feeding the metatarsus were collected from the right and left legs of 4 chicks (2 for each sex) per group. The bone ash and minerals were measured. 1. In respect to the fresh weight of metatarsus bone no significant difference was found between 0 and 1ppm $AFB_1$ treatments, however, decreasing trend was recognized when fed increasing level of $VD_3$(P<.01). 2. The ash content in non-fat dry metatarsus bone decreased when fed 1ppm $AFB_1$(P<.01). However, that increased according to the increasing amount of $VD_3$(P<.01). Although there was no interaction between $AFB_1$ and $VD_3$ it was shown that the 1500IU/kg of $VD_3$ was neccessary to cover the decrease in ash content of metatarsus. when fed 1ppm of $AFB_1$. 3. The Ca contents in metatarsus were not influenced by feeding $AFB_1$ but an increasing trend was verified by feeding increasing levels of $VD_3$(P<.05). 4. The P content decreased as $AFB_1$ was fed(P<.01), while no response was found when fed'different levels of $VD_3$ 5. The Cu content decreased when fed $AFB_1$(P<.05). 6. The Na, Mg, K, Zn, Fe and Mn contents were not affected by feeding $AFB_1$ and /or $VD_3$. Aflatoxin $B_1$($AFB_1$ 0 또는 1ppm)과 Vitamin $D_3$($VD_3$0, 500, 1,000 또는 1,500IU/kg)의 교호작용을 조사코자, Hubbard계통 broiler 병아리 336수를 이용, 2$\times$4 요인시험이 실시되었으며, 전체8처리가 3반복으로 설계되어 탈지건조 중족골의 회분 및 무기물함량과 중량 등을 측정하였다. 얻어진 결과를 요약하면 다음과 같다. L 중족골의 신선중량에 있어서 $AFB_1$ 급여에 의한 차이는 나타내지 않았으며 $VD_3$의 수준이 증가됨에 따라 감소되는 경향을 보였다(P<.01). 2. 탈지건조 중족골의 회분함양을 보면 $AFB_1$의 급여로 인하여 감소되었으며(P<.01), $VD_3$수준이 증가될 때 반대로 증가되었다(P<.01). 교호효과는 인정되지 않았으나 $AFB_1$ 1ppm 급여로 인한 회분감소를 극복하기 위하여 $VD_3$ 1,500IU/kg의 급여가 필요하다는 것이 증명되었다. 3. Ca의 함양은 AFB$_1$급여의 영향을 받지 않았으나 $VD_3$에 의하여 증가되는 경향을 보였다(P<0.05). 4. P의 함양은 $AFB_1$급여로 감소되었으나(P<.01) $VD_3$의 영향은 없었다. 5. Cu의 함양은 AFB$_1$$AFB_1$에 의하여 감소되었다(P<.05). 6. Na Mg, K, Zn, Fe 및 Mn의 함량은 $AFB_1$이나 $VD_3$에 의하여 영향을 받지 않았다.

Two experiments were conducted to investigate the effents of feeding single or combined probiltics on performance and intestinal micreflora of broiler chicks for five weeks. Diets based on corn and soybean meal contained 21.50, 19% CP and 3,100, 3,150kcal/kg ME for starting and finishing period, respectively. Lactobacillus salvarius isolated from chicks intestine(LSC), Lactobacillus salvarius isolated from piglet(LSP), Bacillus polyfermenticus(BP) were fed with alone and mixed ones at the level of 0.21 and 0.1% in experiment 1 and 2, respectively. Three hundred eighty four chicks were randomly assigned to eight treatments with four replicates of 12 chicks each per treatment. Weight gain, feed consumption, feed conversion ratio(FCR) were weekly measured for 5 weeks. The number of intestinal micreflora was examined at the end of experiment. In both experiments, weight gain of chicks fed probiltics tended to be similar or higher than control, but was not in LSC+LSP treatment. Feed intake was not consistent among treatments. In experiment 1, FCR of chicks fed LSC alone was the lowest of all treatments, whereas it was significantly higher in LSC+LSP treatments than control(P〈0.05). In experiment 2, LSP supplemental groups tended to increase FCR compared to the control. The number of ileal E. coli was the lowest in LSP alone treatment of experiment 1, whereas cecal E. coli was higher concentration in probiotics supplemental groups than control. Total Lactobacillus of chicks fed probiotics was decreased in ileum, but was no consestency in cecum. In experiment 2, ileal total yeast tended to be higher in probiotics supplemental groups except LSP alone supplement than control. Total Lactobacillus of chicks fed LSC or LSP alone treatments was significantly higher than control(P〈0.05).
