  • This study was undertaken to assess dietary crude protein (CP) and amino acid (AA) concentrations for growth performance and carcass characteristics in Korean native ducks. In a $2{\times}3$ factorial arrangement, 1-d-old Korean native male ducks were allotted to 6 dietary treatments in a completely randomized design. Experimental diets contained 23 or 21% CP with 1.31/1.09, 1.21/1.00, 1.11/0.91 and 1.11/0.91, 1.02/0.83, 0.92/0.75 AA (Lysine/Total sulfur amino acid, Lysine/TSAA), respectively, from 0 to 3 wk of age. From 4 to 8 wk of age, experimental diets had 19 or 17% of diet; each contained 1.00/0.79, 0.94/0.75, 0.88/0.71 and 0.88/0.71, 0.82/0.67, 0.76/0.63 AA (Lysine/TSAA), respectively. Each dietary treatment has 6 replicates and feed and water were provided ad libitum. Body weight (BW), feed intake and uniformity were measured at 3 wk and 8 wk and carcass characteristics were evaluated at 8 wk of age. As CP increased from 21 to 23%, the BW and BW gain significantly increased (P<0.05) during 0 to 3 wk of age. From 4 to 8 wk of age, BW, feed intake, BW gain, feed conversion rations (FCR) and uniformity were not different (P>0.05) between treatments. Carcass yield and relative weights of liver, spleen, right breast and leg per 100 of BW were not different (P>0.05) between treatments. The meat color, shear force value, cooking loss and pH were not affected by dietary treatments (P<0.05). Korean native ducks require relatively low levels of dietary CP and AA for late growth and carcass yield due to low daily weight gain. This suggests the possible differences in CP and AA needs between Korean native ducks and commercial breeds from foreign breeding companies, especially late growth stage.

  • This study was carried out to evaluate performance and uniformity of White Korean native ducks collected from two areas in Korea. White ducklings were selected from all ducklings that were hatched from hatchery eggs of Korean native ducks. A total of two hundred forty white ducklings (1-d-old) were used in this work and were divided into 4 groups (4 replicates/group, 15 birds/replicate) with $2{\times}2$ factors (2 groups, J, H; genders, male and female). Weekly body weight of H groups was higher than that of J groups (P<0.05). Also, weekly body weight of male ducks was higher compared to that of female at 6~8 wk old (P<0.05). Uniformity of J groups was higher than that of H groups at the age of 1 wks old (P<0.05), and that of female duck was higher than that of male at the age of 6 wks old (P<0.05). Body weight gain of H group was higher than that of J group (P<0.05), and that of male duck was higher compared to that of female at 6~7 wks old (P<0.05). Feed intake of H group was higher compared to that of J group (P<0.05), but there was no significant difference between male and female on feed intake. On feed conversion ratio, J group was higher than H group at 4~5 wks, 7~8 wks and 0~8 wks old (P<0.05), and feed conversion ratio of male duck was higher than that of female at 1~2 wks, 5~6 wks and 6~7 wks old. Finally, these results was tended to show that performance of H groups was higher than that of J groups. Further researches need to carry out to commercial White Korean native ducks on performance and uniformity as well as meat quality and genetic characteristic.

  • This work was carried to evaluate effect of different raising periods on fatty acids and amino acids properties of Korean native commercial ducks. Korean native ducks (n = 90) from National Institute of Animal Science (RDA, Korea) were divided into 6 groups (15 birds/group) and were fed with meat-type duck diets for 8 wk old. When ducks grew at specific wk (6, 7 and 8 weeks), 2 ducks per group were slaughtered at 6, 7 and 8 wk old. Myristic acid (C14:0) and palmitic acid (C16:0) of saturated fatty acid (SFA) were the highest and arachidonic acid of unsaturated fatty acid (USFA) was the lowest at the age of 6 weeks old (P<0.05) at the age of 6 weeks old among treatments. Stearic acid of SFA was the highest at the age of 7 weeks old among treatments. There was no significant difference on other fatty acids among treatments. SFA and USFA have significant difference at the age of 8 weeks (P<0.05). Histidine, leucine, lysine, methionine, phenylalanine and threonine of essential amino acid increased with passing weeks (P<0.05). There was no significant difference on isoleucine and valine (P>0.05). Every non-essential amino acids were the highest at the age of 8 weeks among treatments (P<0.05). In conclusion, fatty acid contents and amino acid contents increased until the age of 8 weeks old, but further research was needed because of deficiency of data to suggest the correct shipping time.

  • This study was conducted to compare and analyze meat quality of Korean native duck (KND) meat relative to stocking density. The stocking densities under investigation were 4, 5, 6, 7, 8 and 9 birds/㎡. The experiment comprised six treatments and four replications, wherein the breast meat (pH, meat color, and physicochemical properties) and leg meat (fatty acid contents) of 8-week-old KNDs (2.8±0.2 kg) were used. pH of breast meat decreased linearly and quadratically (P<0.05) as stocking density increased. Ash content also decreased linearly (P<0.05) as stocking density increased; however, moisture, fat, and protein contents did not differ significantly among treatments. Furthermore, meat color and cooking loss (CL) increased linearly (P<0.05) as stocking density increased whereas neither shear force (SF) nor water holding capacity (WHC) displayed a significant difference among treatments. Palmitic acid (C16:0) and stearic acid (C18:0) contents decreased quadratically (P<0.05) as stocking density increased whereas, conversely, linoleic acid (C18:1n9) and eicosenoic acid (C20:1n9) contents increased linearly (P<0.05) as stocking density increased. Additionally, γ-linoleic acid (C18:3n6) content increased linearly and quadratically (P<0.05) as stocking density increased, but a decrease (P<0.05) was observed in arachidonic acid (C20:4n6) content. Saturated fatty acid (SFA) and total unsaturated fatty acid (TUFA) contents did not show significant differences among treatments relative to stocking density. However, monounsaturated fatty acid (MUFA) content increased linearly (P<0.05) and polyunsaturated fatty acid (PUFA) content decreased linearly (P<0.05) as stocking density increased. These results can be utilized as basic data for research on the effect of stocking density on KNDs.

  • This study was undertaken to assess dietary CP and ME concentrations for optimum growth performance and carcass characteristics of Korean Native male ducks. In a $3{\times}3$ factorial arrangement, 1-d-old Korean Native male ducks were completely randomized design to experimental diets with 3,000, 2,900, and 2,800 kcal of ME/kg of diet; each contained 23, 22, and 21% CP, respectively, from 0 to 3 wk of age. From 4 to 8 wk of age, experimental diets had 3,100, 3,000, and 2,900 kcal of ME/kg of diet, and each contained 19, 18, and 17% CP, respectively. Each dietary treatment was replicated 4 times, and feed and water were provided ad libitum. Body weight, feed intake and uniformity were measured at 3 wk and 8 wk, and carcass characteristics were evaluated at 8 wk. As CP increased from 21 to 23 %, the body weight, BW gain and feed conversion ratios (FCR) linearly improved (P<0.01) during 0 to 3 wk of age. From 4 to 8 wk of age, the body weight, feed intake, BW gain, FCR and uniformity were not different (P>0.05). Carcass ratios of birds fed 3,000 kcal of ME/kg diets from 3 to 8 wk of age were quadratically increased significantly (P<0.01). As ME and CP increased, respectively, relative weight of liver weight per 100 g of BW was linearly decreased (P<0.01). Relative weights of left breast, thigh and drumstick weight per 100 of BW were not different (P>0.05). Also, breast meat color, pH, cooking loss and shear force were not different (P>0.05). Thus, diets with 2,800 kcal of ME/kg and 23% CP or with 2,900 kcal of ME/kg and 17% CP at 0 to 3 wk and 4 to 8 wk, respectively, were used more efficiently. However, diets with 3,000 kcal of ME/kg at 4 to 8 wk in carcass rate was quadratically increased.

  • This study was carried out to investigate the growth performance and the carcass ratio of meat-type Korean Native Ducks. Four hundred twenty Korean Native Ducks' chicks were selected and divided into four treatments (7 replications/ treatment, 15 birds/replication) by strains (A and B) and gender(male and female) with $2{\times}2$ fractal factors. There was no significant difference between A and B on the body weight at 2, 4, 6, and 8 weeks old (P>0.05). However, body weight of female was higher at 2 weeks old than male while that of male was higher at the 8 weeks old (P<0.01). Daily feed intake of male was higher compared to female during 6~8 weeks (P<0.05). On weekly body weight gain, there was no significant difference between strains, but gained body weight of male was higher until 2 weeks old while that of female was higher during 6~8 weeks (P<0.01). On the live body weight and carcass weight by strains and genders, B strain was higher than A strains at the 8 weeks of age (P<0.01). Carcass yield was the highest at 8 weeks of age in both strains (P<0.05). These results may provided the basic data on growth performance and carcass ratio of meat-type Korean Native Ducks.

  • This work was carried out to investigate the performance of growing period of large-type Korean native ducks. A total of four hundred twenty female and male duck chicks generated from A and B strains of ducks. Groups were four crossbreds (3 replications/crossbred, 35 birds/replication) as $2{\times}2$ factors (2 strains, A and B; 2 genders, female and male). On the body weight, male of B strains was the highest among 4 treatments after the age of 4 week (P<0.05). Body weight of B strain was higher than that of A strain at all period (P<0.05). Body weight of male was higher compared to that of female after the age of 4 week (P<0.05). On the body weight gain, male of B strain was the highest and female of A strain was the lowest among 4 treatments at 0~8, 0~12, 0~16 and 0~20 weeks (P<0.05). Body weight gain of male was higher than that of female after the age of 4 week (P<0.05). On the feed intake, male of B strain was the highest among 4 treatments from the age of 0 week and to the age of 4, 12, 16 and 20 week (P<0.05). Feed intake of male was higher than that of female at 0~12, 0~16 and 0~20 weeks (P<0.05). On the feed conversion ratio, male of B strain was the highest among other treatments 0~4 weeks and female of A strain was at 0~8 and 0~12 weeks (P<0.05). Feed intake of female was higher compared to that of female at 0~8 weeks and male was high at 0~20 weeks. These results provided the basic data on the record of growing phase of large-type Korean native ducks.

  • This work was carried out to investigate the performance of early laying period of large-type Korean native ducks. One hundred sixty eight ducks were used in this work and divided into A and B strains (6 replications/strain, 14 birds/replication). The days at first egg of A and B strains were the age of 154.5 and 154.7 days, egg weights were 69.1 g and 65.5 g, and body weights were 3,187 g and 3,105 g at the period of laying the first egg, respectively. The days at sexual maturity of A and B strains were the age of 175.8 and 171.5 days, egg weights were 75.2 g and 74.9 g, and body weights were 3,245 g and 3,225 g at the period of laying the first egg, respectively. There were no significant differences on the day of first egg, the day of sexual maturity, egg weight and body weight at first egg and the sexual maturity, average body weight, and daily feed intake between A and B strains (P>0.05). The day of the sexual maturity of B strain was earlier than that of A strain (P<0.05). However, weekly body weight was the highest at the age of 28 weeks (P<0.05), and weekly feed intake increased after 26 weeks old (P<0.05). Egg production (%) of B strain was higher than that of A strain at the age of 22~24 weeks (P<0.05), but there was no significant difference on egg production (%) the other weeks. A number of egg laid of B strain was higher than A strain at 22~24 weeks old (P<0.05). Feed conversion ratio of A and B strains were 10.7 and 6.53 at 24~24 weeks old, respectively, so feed conversion ratio of A strain was higher than that of B strain (P<0.05). Weekly feed conversion ratio wes the highest at 20~22 weeks old, and significantly decreased until 24~24 weeks old, but were lowly maintained from the age of 24 weeks to the age of 30 weeks. These results provided the basic data on the record of early laying period of large-type Korean native ducks.
