발정동기화에 의해 분만된 한국재래산양의 인공포유시험 = A Trial on Artificial Suckling of Korean Native Goat Kid Born by Estrus Synchronization

다국어 초록 (Multilingual Abstract)

This trial was conducted on 10 Korean native goat kids which were born by estrus synchrozation and seperated from their dams at 8 days of age. The kids were fed mesh raw milk from Holstein cows at regular intervals of three times daily by infant nursing bottle from 8 up to 59 days of age, and also provided pre-starter as well as Italian ryegrass hay from 14 days of age.
Throughout the experimental period, daily amount of milk, pre-starter and Italian ryegrass hay consumed per kid was recorded. Live weight was measured at regular intervals of 3 days from 5 days of age till weaning, and thereafter at intervals of 15 days up to 119 de s of age. Growth rate per day were calculated during the total gain in weight.
The average daily amount of milk consumed per kid was about 474 ml at the beginning and thereafter increased progressively until kids reached their peak(about 1,300 ml) by 41 days of age. The average total milk consumption per kid over the experimental period was about 51,000 ml.
The kids started eating pre-starter and Italian ryegrass hay regularly around 32 days of age. The average daily amount of pre-starter consumed per kid was 10-l3g during 32-47 days of age and reached about 70g at weaning. The average daily amount of Italian ryegrass hay consumed per kid was 30g around 32 days and reached about 80g at weaning.
The average birth weight of experimental kids was 1.79(±0.23) kg. The average daily gains of experimental kids showed 0.1 kg througout the experimental period and the average body weight of kids reached 8.14 kg at weaning .After weaning, the average body weight of kids reached 8.53 kg at 74 days, 9.55 kg at 89 days, 13.3 kg at 119 days of age, respectively.
