Jin-ding duck is noted for egg-production in Fujien Province. Jin-ding village, the native place of the Jin-ding duck, offers favorable environmental conditions for raising ducks. It has a long history of duck breeding of more than 200 years, and possesses a complete controlling system for rearing(?)ducks on the sea-shore. A high record of egg-production averaging 250 eggs per duck per year has been creared by this village.With the cooperation of the Jin-ding production team, we attempted to increase the Jin-ding duck's egg-production. In October, 1958, 240 fernale ducks of good quality were selected to carry out the first experiment. As a result of improving the method of feeding and controlling, and of artificial acceleration of the metabolic rate, a high record of annual production(346,2 eggs per female)was attained. The success of the experiment was achieved mainly by the elimination of the resting period, i. e. the period without egg production.Upon the basis of the experience gained in the first experiment, second experiment was carried out in April, 1959, with the object of giving better care arid rearing during the duckling stage. The outcome of the experiment was shown in the further increase of egg-productlon, reaching a higher record of annual production(average 360.9 eggs per female).The two experiments mentioned above were not only successful in eliminating the resting period in egg-production but also in altering the habit of moulting, i. e. change of feathers independent of seasons.

本文报导本教研组与福建省龙海县金定生产大队协作,大搞土洋结合,就提高金定鸭产蛋量的问题进行了试验研究的成果。 1958年10月,我们精选240只优良母鸭组成第一试验鸭(?)进行实验,在金定村原有养鸭经验的基础上,从加强饲养管理的措拖及人工地促进鸭子新陈代谢入手,突破了鸭子的秋冬季休产期,创造了鸭(?)平均每只年产蛋量346.2枚的成绩。 1959年4月,在第一试验鸭(?)已取得的经验基础上建立第二试验鸭(?)。试验系自雏鸭阶段开始,就给予良好的培育和训练。实践的结果产蛋量达到更高的水平,大(?)饲养平均每只母鸭的年产蛋量360.9枚,年平均产蛋率达到98.63%。 (?)阵鸭(?)试验的结果,除了突破休产期,产蛋量显著提高外,同时,换羽特(?)也发生改变,换羽不集中在一个季节,并是边换羽边产蛋。

The purpose of this experiment is trying to find out the best economical hybridized combination of partridge sichuan ducks, which would grow faster, have heavier body weight and higher meat production as well as be fit for running in the paddy fields. The results showed that jian-chuan hybrid had a number of favourable attributes over Jing-Chuan and Di-Chuan hybrids. The former reached 1. 5kg of market body weight about 15 days earlier than the control group of partridge sichuan duck nomadizing in the paddy...

The purpose of this experiment is trying to find out the best economical hybridized combination of partridge sichuan ducks, which would grow faster, have heavier body weight and higher meat production as well as be fit for running in the paddy fields. The results showed that jian-chuan hybrid had a number of favourable attributes over Jing-Chuan and Di-Chuan hybrids. The former reached 1. 5kg of market body weight about 15 days earlier than the control group of partridge sichuan duck nomadizing in the paddy fields under the same conditions. The muscle weight of breast and thigh of Jian-Chuan hybrid ducks at 60 days of age was20% heavier than that of partridge sichuan ducks. Jian-chuan, therfore, is an ideal combination for developing duck industry in Sichuan Province.

本试验的目的在于试图筛选出生长快、体重较大、产肉量较高并适于稻田放牧的四川麻鸭经济杂交组合。试验结果表明,建川杂交鸭比京川和狄川杂交鸭具有许多有利的特质。在相同的放牧条件下,建川杂交鸭比四川麻鸭提早15天达到1.5公斤的上市体重,胸鸭肌重比四川麻鸭高出20%以上。这是适于我省发展稻田养鸭业,与水稻收获季节紧密配合,节约用粮,短期内可提供优质肉用仔鸭上市的一个比较理想的经济杂交组合。1984年已在名山县推广20余万只。

Partridge Sichuan(S)ducks were crossed with Jianchang (J), Peking(P) and Tegel (T) drakes, with the purebreds intermated as control groups. The Body weights(B.W.) of 368 ducklings in all of the breeds and crossbreds were recorded from day-old to 60 and 70 days of age in every 10 days under the condition of nomadizing in paddy fields, and then slaughtered for carcass analysis.The B.W.of J×S, P×S and T×S were 1458.0, 1500.0 and 1436.0 g at 60 days of age, and 1638.5, 1792.05 and 1648.0 g at 70 days of...

J×S and P X S were heavier than their parents.The heterosis for the B.W. were generally positive and statistically significant. The weights of carcass, breast muscl and thigh muscle were higher for crosses than for their parents and significant heterosis was observed for the former two traits at 60 days of of age. The contents of Lysine and Methionine in the breast plus thigh muscle were the highest for J×S, and Tegel ducks were the fattest in the breeds and crossbreds.

用四川麻鸭母鸭与建昌鸭、北京鸭和狄高鸭公鸭杂交,纯种设平行的对照。在放牧为主、人工给饲为辅的条件下每隔10日龄测定鸭群至70日龄的体重,并于60和70日龄分别屠宰一半,进行屠体分析。建川、京川和狄川鸭60日龄体重分别为1458.0、1500.0和1436.0克,70日龄分别为1638.5、1792.5和1648.0克,均显著高于四川麻鸭(p<.05)建川和京川还具超双亲表现。自出壳至70日龄体重的杂种优势一般较高而显著。60日龄建川、京川和狄川鸭屠体重(分别为884.0、887.0和882.5克),胸肌重(分别为59.2、49.7和50.5克)和腿肌重(分别为142.4、140.2和136.6克)均超过各自的双亲,屠宰性状的杂种优势,建川和狄川70日龄比60日龄明显下降,而京川则有上升之势。建川鸭胸腿肌赖氨酸和蛋氨酸含量居参试品种和杂种之首,屠体脂肪含量以狄高鸭最高。试验还观察到三个优良肉用品种在放牧为主的条件下不能发挥其快速生长潜力。据此,在四川稻田养鸭条件下推广这三个杂种,可获较大的经济效益。
