Abstract

An experiment was conducted at AZ-Zahra Farm, Sandakan, Sabah, Malaysia to investigate the productive and reproductive performance of Saanen dairy goat. Body weight at different ages were collected once while birth weight was collected when does gave birth. On the other hand, milk production of each individual per day was received continuously for three months. The data on reproductive parameters such as length of estrus cycle, duration of estrus period, age at puberty, gestation length, age at first kidding, litter size, birth weight and kid mortality were noted. Descriptive statistics such as number, percentage, mean, standard deviation were performed. T-test was also conducted to know the statistical difference between the groups. Result demonstrated that body weight increases significantly (p<0.01) with the advancement of the age. The highest daily milk yield was found in 2-3 years of age. Dam with multiple kids produced more milk than dam with single kid. Estrus cycle of Saanen goats was found 21 days, the average estrus period duration was 2.75 days, age at puberty was 8.33 months, first kidding age was 14.2 months and gestation period was 150 days on an average. With the increase of the age of dam litter size increased. Meanwhile average birth weight increased as age of dam increased from 2.85 kg in 1 year to 3.26 kg in 3 years. Male kids born heavier than females (3.23±0.62 vs. 2.75±0.58 kg) and single kids were heavier than twin kids (3.07±0.66 kgvs2.70±0.28 kg). Low mortality rate of kids was recorded in this study (6.4%). It can be concluded that the overall productive and reproductive performances of Saanen goat at AZ-Zahra farm were within the acceptable level and the variation recorded in different parameters is very much usual.

马来西亚山打根AZZahra农场Saanen山羊的生产和繁殖性能
在马来西亚沙巴州山打根的AZ-Zahra农场进行了一项试验,以调查Saanen奶山羊的生产和繁殖性能。在不同年龄收集一次体重,在分娩时收集出生体重。另一方面,每个个体每天的产奶量连续三个月。记录了发情周期长短、发情期持续时间、青春期年龄、妊娠期长短、初开玩笑年龄、产仔数、出生体重和儿童死亡率等生殖参数的数据。进行描述性统计,如数量、百分比、平均值、标准差。并进行t检验,了解组间的统计学差异。结果显示,随着年龄的增长,体重显著增加(p<0.01)。日产奶量在2 ~ 3岁时最高。有多个孩子的大坝比只有一个孩子的大坝产出更多的牛奶。沙嫩山羊发情周期21天,平均发情期2.75天,发情年龄8.33个月,初开胎龄14.2个月,平均妊娠期150天。随着坝龄的增加,凋落物大小也随之增加。平均出生体重随着坝龄的增加而增加,从1年的2.85 kg增加到3年的3.26 kg。男婴比女婴重(3.23±0.62 vs 2.75±0.58 kg),单胞胎比双胞胎重(3.07±0.66 kgvs2.70±0.28 kg)。儿童死亡率较低(6.4%)。综上所述,AZ-Zahra农场萨南山羊的生产和繁殖性能总体处于可接受的水平,各参数记录的变化非常普遍。爆炸。j .似的。科学》2018。47 (1): 1-12
